Brain-inspired Affective Empathy Mechanisms
Abstract
> As AI closely interacts with human society, it is crucial to ensure that its decision-making is safe, altruistic, and aligned with human ethical and moral values. However, existing research on embedding ethical and moral considerations into AI remains insufficient, and previous external constraints based on principles and rules are inadequate to provide AI with longterm stability and generalization capabilities. In contrast, the intrinsic altruistic motivation based on empathy is more willing, spontaneous, and robust. Therefore, this paper is dedicated to autonomously driving intelligent agents to acquire morally behaviors through human-like affective empathy mechanisms. We draw inspiration from the neural mechanism of human brain’s moral intuitive decision-making, and simulate the mirror neuron system to construct a brain-inspired affective empathydriven altruistic decision-making model. Here, empathy directly impacts dopamine release to form intrinsic altruistic motivation. Based on the principle of moral utilitarianism, we design the moral reward function that integrates intrinsic empathy and extrinsic self-task goals. A comprehensive experimental scenario incorporating empathetic processes, personal objectives, and altruistic goals is developed. The proposed model enables the agent to make consistent moral decisions (prioritizing altruism) by balancing self-interest with the well-being of others. We further introduce inhibitory neurons to regulate different levels of empathy and verify the positive correlation between empathy levels and altruistic preferences, yielding conclusions consistent with findings from psychological behavioral experiments. This work provides a feasible solution for the development of ethical AI by leveraging the intrinsic human-like empathy mechanisms, and contributes to the harmonious coexistence between humans and AI.

9006b312-244b-4a14-a388-8f4c2be541c5 | StampyAI/alignment-research-dataset/lesswrong | LessWrong | Winners-take-how-much?
The treatments I have seen to date of the "winner-takes-all'' dynamic in AI development focus on the risk-taking engendered by this dynamic: the more AI researchers have to gain from being early movers, the stronger the incentive to cut corners in safety measures. Concern about a result in which a small number of winners has successfully emerged, without, that is, blowing everything up in the effort, seems to be muted. "Winner-takes-all," in other words, is intended only as a term of art from conventional political economy, where "all" refers to the spoils of an otherwise limited contest between willing contestants. The runners-up may lose their investments, but not their lives.
To put it another way, we could describe the prevailing model as having three contests: 1) between all humans and a hypothetical uncontrolled AI; 2) between firms racing to establish monopolistic advantage in the production and sale of controlled AI; 3) between humans in general and these firms over the unprecedented risks imposed by the latter on the former, intermixed with a conventional struggle between the former as consumers and the latter as would-be monopoly producers. Of the three contests, the risk of unconstrained rivalrous behavior -- that is, a fight to the death -- is only considered to apply to the one between the hypothetical uncontrolled AI and all humans, collectively.
What seems to me to be missing from this model is a rivalrous intra-species fight to the death. This should be surprising, given that we posit a jealous AI, built and trained by humans, acquiring and pursuing goals that put it in opposition to the existence of 100% of humans. We should also fear humans with AI acquiring and pursuing goals that put them in opposition to the existence of the other humans.
This could be treated as a semantic problem, if we define any genocidal application of AI to be a form of "misalignment," whether the AI is manipulating humans to achieve murderous ends or vice versa. My test for the usefulness of a distinction between these two cases is whether or not we can imagine a significant subset of AI development firms willingly pursuing the genocidal path, rather than treating all such paths as equally aberrant. This test is, after all, where the rubber meets the road. Obviously, all firms wish to avoid a paperclip maximizer (that is the whole point of the paperclip maximizer example, to describe a being using its superintelligence to pursue horrifically ludicrous ends). We can imagine human genocidal fanatics and cultists aiming to acquire AI technology, but a random sample of AI developers would deem such goals to be contrary to their own goals and, furthermore, self-defeating in the long run, in the sense that they would be contributing to a world that no one should objectively prefer to live in -- a world filled with lethal strife over religious beliefs.
But there are conditions under which genocidal goals would be rational. On the contrary, willingly suffering a perpetual competition with 8-10 billion other people for the planet's limited resources is generally *irrational*, given a good alternative. So if one could shrink the population down by, say, 99.9%, the world could be a permanently better place for the remaining population. Unlike ideologically driven genocide, such a pivotal event would establish no self-defeating precedent, as all the newly down-sized population would have to do to avoid further genocide is to maintain itself at a mutually agreed-upon size, a far less onerous task than, say, maintaining homogeneity of belief. In short, I don't think it would be impossible or even that difficult to convince a significant set of actors capable of AI development to view a "small is beautiful" utopia as a goal that is aligned with their own interests. Therefore, this concern does not belong in the same "X-risk" class as those involving the extinction of humanity (via paperclip maximization or otherwise).
It may be that the only way to avoid the universally undesirable outcome of AI killing *all* humans is via avoidance of killing *any* humans, or some other small number. Although I can't speak knowledgeably about AI safety methods, this seems like it would be a happy but unlikely coincidence. What seems to me to be more likely is the opposite, that a small population would actually *decrease* the chances of a complete AI disaster, because a small population can more easily govern and monitor its own application of AI, and because the power and sophistication of its automation could operate at a much smaller scale, leaving more room between AI usefulness and risk. I suspect that similar reasoning applies to the problem of getting to a small population. With enough collusion between AI developers and the element of surprise, the artificial intelligence requirements to simply kill 99.9% of the population in an isolated event perhaps need not be very close to human level (see [this post](https://www.lesswrong.com/posts/7SBAjSjENLyzdnC2f/minimum-viable-exterminator) for a treatment of the minimum intelligence requirements for killing lots of people).
So I'm concerned that the "winner-takes-all" contest to pay attention to is *not* the gentleman's innovation race between AI development firms to bring the best AI to consumers (safety be damned!), but between any combination of small groups armed with AI that is "just good enough" and the rest of population for a place on this planet. The upshot would be that, from the perspective of the average person, whether or not AI ends up taking the operators down with everyone else is purely an academic concern. |
b1c0ace6-92c5-49a4-a1df-9b65543f9a96 | trentmkelly/LessWrong-43k | LessWrong | Funding Good Research
Series: How to Purchase AI Risk Reduction
I recently explained that one major project undergoing cost-benefit analysis at the Singularity Institute is that of a scholarly AI risk wiki. The proposal is exciting to many, but as Kaj Sotala points out:
> This idea sounds promising, but I find it hard to say anything about "should this be funded" without knowing what the alternative uses for the money are. Almost any use of money can be made to sound attractive with some effort, but the crucial question in budgeting is not "would this be useful" but "would this be the most useful thing".
Indeed. So here is another thing that donations to SI could purchase: good research papers by skilled academics.
Our recent grant of $20,000 to Rachael Briggs (for an introductory paper on TDT) provides an example of how this works:
1. SI thinks of a paper it wants to exist but doesn't have the resources to write itself (e.g. a clearer presentation of TDT).
2. SI looks for a few productive academics well-suited to write the paper we have in mind, and approaches them directly with the grant proposal. (Briggs is an excellent choice for the TDT paper because she is a good explainer and has had two of her past decision theory papers selected as among the 10 best papers of the year by The Philosopher's Annual.)
3. Hopefully, one of these academics says "yes." We award them the grant in return for a certain kind of paper published in one of a pre-specified set of journals. (In the case of the TDT grant to Rachael Briggs, we specified that the final paper must be published in one of the following journals: Philosopher's Imprint, Philosophy and Phenomenological Research, Philosophical Quarterly, Philosophical Studies, Erkenntnis, Theoria, Australasian Journal of Philosophy, Nous, The Philosophical Review, or Theory and Decision.)
4. SI gives regular feedback on outline drafts and article drafts prepared by the article author.
5. Paper gets submitted, revised, and published!

ad0e8b5b-54c7-4f4e-875e-04a5ac899527 | trentmkelly/LessWrong-43k | LessWrong | Remaking EfficientZero (as best I can)
Introduction
When I first heard about EfficientZero, I was amazed that it could learn at a sample efficiency comparable to humans. What's more, it was doing it without the gigantic amount of pre-training the humans have, which I'd always felt made comparing sample efficiencies with humans rather unfair. I also wanted to practice my ML programming, so I thought I'd make my own version.
This article uses what I've learned to give you an idea, not just of how the EfficientZero algorithm works, but also of what it looks like to implement in practice. The algorithm itself has already been well covered in a LessWrong post here. That article inspired me to write this and if it's completely new to you it might be a good place to start - the focus here will be more on what the algorithm looks like as a piece of code.
The code below is all written by me and comes from a cleaned and extra-commented version of EfficientZero which draws from the papers (MuZero, Efficient Zero), the open implementation pf MuZero by Werner Duvaud, the pseudocode provided by the MuZero paper, and the original implementation of EfficientZero.
You can have a look at the full code and run it at on github. It's currently functional and works on trivial games like cartpole but struggles to learn much on Atari games within a reasonable timeframe, not certain if this reflects an error or just insufficient time. Testing on my laptop or Colab for Atari games is slow - if anyone could give access to some compute to do proper testing that would be amazing!
Grateful to Misha Wagner for feedback on both code and post.
Algorithm Overview
AlphaZero
EfficientZero is based on MuZero, which itself is based on AlphaZero, a refinement of the architecture which was the first beat the Go world champion. With AlphaZero, you play a deterministic game, like chess, by developing a neural network that evaluates game states, associating each possible state of the board with a value, the discounted expected return (in |
895915d3-bf8c-4ecf-8bc3-5fd21879017a | StampyAI/alignment-research-dataset/blogs | Blogs | AGI Ruin: A List of Lethalities
### Preamble:
(If you’re already familiar with all basics and don’t want any preamble, skip ahead to [Section B](https://intelligence.org/feed/?paged=2#Section_B_) for technical difficulties of alignment proper.)
I have several times failed to write up a well-organized list of reasons why AGI will kill you. People come in with different ideas about why AGI would be survivable, and want to hear different *obviously key*points addressed first. Some fraction of those people are loudly upset with me if the obviously most important points aren’t addressed immediately, and I address different points first instead.
Having failed to solve this problem in any good way, I now give up and solve it poorly with a poorly organized list of individual rants. I’m not particularly happy with this list; the alternative was publishing nothing, and publishing this seems marginally more [dignified](https://www.lesswrong.com/posts/j9Q8bRmwCgXRYAgcJ/miri-announces-new-death-with-dignity-strategy).
Three points about the general subject matter of discussion here, numbered so as not to conflict with the list of lethalities:
**-3**. I’m assuming you are already familiar with some basics, and already know what ‘[orthogonality](https://arbital.com/p/orthogonality/)’ and ‘[instrumental convergence](https://arbital.com/p/instrumental_convergence/)’ are and why they’re true. People occasionally claim to me that I need to stop fighting old wars here, because, those people claim to me, those wars have already been won within the important-according-to-them parts of the current audience. I suppose it’s at least true that none of the current major EA funders seem to be visibly in denial about orthogonality or instrumental convergence as such; so, fine. If you don’t know what ‘orthogonality’ or ‘instrumental convergence’ are, or don’t see for yourself why they’re true, you need a different introduction than this one.
**-2**. When I say that alignment is lethally difficult, I am not talking about ideal or perfect goals of ‘provable’ alignment, nor total alignment of superintelligences on exact human values, nor getting AIs to produce satisfactory arguments about moral dilemmas which sorta-reasonable humans disagree about, nor attaining an absolute certainty of an AI not killing everyone. When I say that alignment is difficult, I mean that in practice, using the techniques we actually have, “please don’t disassemble literally everyone with probability roughly 1” is an overly large ask that we are not on course to get. So far as I’m concerned, [if you can get a powerful AGI that carries out some pivotal superhuman engineering task, with a less than fifty percent change of killing more than one billion people](https://twitter.com/ESYudkowsky/status/1070095112791715846), I’ll take it. Even smaller chances of killing even fewer people would be a nice luxury, but if you can get as incredibly far as “less than roughly certain to kill everybody”, then you can probably get down to under a 5% chance with only slightly more effort. Practically all of the difficulty is in getting to “less than certainty of killing literally everyone”. Trolley problems are not an interesting subproblem in all of this; if there are any survivors, you solved alignment. At this point, I no longer care how it works, I don’t care how you got there, I am cause-agnostic about whatever methodology you used, all I am looking at is prospective results, all I want is that we have justifiable cause to believe of a pivotally useful AGI ‘this will not kill literally everyone’. Anybody telling you I’m asking for stricter ‘alignment’ than this has failed at reading comprehension. The big ask from AGI alignment, the basic challenge I am saying is too difficult, is to obtain by any strategy whatsoever a significant chance of there being any survivors.
**-1**. None of this is about anything being impossible in principle. The metaphor I usually use is that if a textbook from one hundred years in the future fell into our hands, containing all of the simple ideas *that actually work robustly in practice,* we could probably build an aligned superintelligence in six months. For people schooled in machine learning, I use as my metaphor the difference between ReLU activations and sigmoid activations. Sigmoid activations are complicated and fragile, and do a terrible job of transmitting gradients through many layers; ReLUs are incredibly simple (for the unfamiliar, the activation function is literally max(x, 0)) and work much better. Most neural networks for the first decades of the field used sigmoids; the idea of ReLUs wasn’t discovered, validated, and popularized until decades later. What’s lethal is that we do not *have*the Textbook From The Future telling us all the simple solutions that actually in real life just work and are robust; we’re going to be doing everything with metaphorical sigmoids on the first critical try. No difficulty discussed here about AGI alignment is claimed by me to be impossible – to merely human science and engineering, let alone in principle – if we had 100 years to solve it using unlimited retries, the way that science *usually* has an unbounded time budget and unlimited retries. This list of lethalities is about things *we are not on course to solve in practice in time on the first critical try;* none of it is meant to make a much stronger claim about things that are*impossible in principle.*
That said:
Here, from my perspective, are some different true things that could be said, to contradict various false things that various different people seem to believe, about why AGI would be survivable on anything remotely remotely resembling the current pathway, or any other pathway we can easily jump to.
### Section A:
This is a very lethal problem, it has to be solved one way or another, it has to be solved at a minimum strength and difficulty level instead of various easier modes that some dream about, we do not have any visible option of ‘everyone’ retreating to only solve safe weak problems instead, and failing on the first really dangerous try is fatal.
**1**. Alpha Zero blew past all accumulated human knowledge about Go after a day or so of self-play, with no reliance on human playbooks or sample games. Anyone relying on “well, it’ll get up to human capability at Go, but then have a hard time getting past that because it won’t be able to learn from humans any more” would have relied on vacuum. **AGI will not be upper-bounded by human ability or human learning speed**. **Things much smarter than human would be able to learn from less evidence than humans require** to have ideas driven into their brains; there are theoretical upper bounds here, but those upper bounds seem very high. (Eg, each bit of information that couldn’t already be fully predicted can eliminate at most half the probability mass of all hypotheses under consideration.) It is not naturally (by default, barring intervention) the case that everything takes place on a timescale that makes it easy for us to react.
**2**. **A cognitive system with sufficiently high cognitive powers, given any medium-bandwidth channel of causal influence, will not find it difficult to bootstrap to overpowering capabilities independent of human infrastructure.** The concrete example I usually use here is nanotech, because there’s been pretty detailed analysis of what definitely look like physically attainable lower bounds on what should be possible with nanotech, and those lower bounds are sufficient to carry the point. My lower-bound model of “how a sufficiently powerful intelligence would kill everyone, if it didn’t want to not do that” is that it gets access to the Internet, emails some DNA sequences to any of the many many online firms that will take a DNA sequence in the email and ship you back proteins, and bribes/persuades some human who has no idea they’re dealing with an AGI to mix proteins in a beaker, which then form a first-stage nanofactory which can build the actual nanomachinery. (Back when I was first deploying this visualization, the wise-sounding critics said “Ah, but how do you know even a superintelligence could solve the protein folding problem, if it didn’t already have planet-sized supercomputers?” but one hears less of this after the advent of AlphaFold 2, for some odd reason.) The nanomachinery builds diamondoid bacteria, that replicate with solar power and atmospheric CHON, maybe aggregate into some miniature rockets or jets so they can ride the jetstream to spread across the Earth’s atmosphere, get into human bloodstreams and hide, strike on a timer. **Losing a conflict with a high-powered cognitive system looks at least as deadly as “everybody on the face of the Earth suddenly falls over dead within the same second”.** (I am using awkward constructions like ‘high cognitive power’ because standard English terms like ‘smart’ or ‘intelligent’ appear to me to function largely as status synonyms. ‘Superintelligence’ sounds to most people like ‘something above the top of the status hierarchy that went to double college’, and they don’t understand why that would be all that dangerous? Earthlings have no word and indeed no standard native concept that means ‘actually useful cognitive power’. A large amount of failure to panic sufficiently, seems to me to stem from a lack of appreciation for the incredible potential lethality of this thing that Earthlings as a culture have not named.)
**3**. **We need to get alignment right on the ‘first critical try’** at operating at a ‘dangerous’ level of intelligence, where **unaligned operation at a dangerous level of intelligence kills everybody on Earth and then we don’t get to try again**. This includes, for example: (a) something smart enough to build a nanosystem which has been explicitly authorized to build a nanosystem; or (b) something smart enough to build a nanosystem and also smart enough to gain unauthorized access to the Internet and pay a human to put together the ingredients for a nanosystem; or (c) something smart enough to get unauthorized access to the Internet and build something smarter than itself on the number of machines it can hack; or (d) something smart enough to treat humans as manipulable machinery and which has any authorized or unauthorized two-way causal channel with humans; or (e) something smart enough to improve itself enough to do (b) or (d); etcetera. We can gather all sorts of information beforehand *from less powerful systems that will not kill us if we screw up operating them;* but once we are running more powerful systems, we can no longer update on sufficiently catastrophic errors. This is where practically all of the real lethality comes from, that we have to get things right on the first sufficiently-critical try. If we had unlimited retries – if every time an AGI destroyed all the galaxies we got to go back in time four years and try again – we would in a hundred years figure out which bright ideas actually worked. Human beings can figure out pretty difficult things over time, when they get lots of tries; when a failed guess kills literally everyone, that is harder. That we have to get a bunch of key stuff right *on the first try* is where most of the lethality really and ultimately comes from; likewise the fact that no authority is here to tell us a list of what exactly is ‘key’ and will kill us if we get it wrong. (One remarks that most people are so absolutely and flatly unprepared by their ‘scientific’ educations to challenge pre-paradigmatic puzzles with no scholarly authoritative supervision, that they do not even realize how much harder that is, or how incredibly lethal it is to demand getting that right on the first critical try.)
**4**. **We can’t just “decide not to build AGI”** because GPUs are everywhere, and knowledge of algorithms is constantly being improved and published; 2 years after the leading actor has the capability to destroy the world, 5 other actors will have the capability to destroy the world. **The given lethal challenge is to solve within a time limit,** driven by the dynamic in which, over time, increasingly weak actors with a smaller and smaller fraction of total computing power, become able to build AGI and destroy the world. Powerful actors all refraining in unison from doing the suicidal thing just delays this time limit – it does not lift it, unless computer hardware and computer software progress are both brought to complete severe halts across the whole Earth. The current state of this cooperation to have every big actor refrain from doing the stupid thing, is that at present some large actors with a lot of researchers and computing power are led by people who vocally disdain all talk of AGI safety (eg Facebook AI Research). Note that needing to solve AGI alignment *only* within a time limit, but with unlimited safe retries for rapid experimentation on the full-powered system; or *only* on the first critical try, but with an unlimited time bound; would both be terrifically humanity-threatening challenges by historical standards *individually*.
**5**. **We can’t just build a very weak system**, which is less dangerous because it is so weak, and declare victory; because later there will be more actors that have the capability to build a stronger system and one of them will do so. I’ve also in the past called this the ‘safe-but-useless’ tradeoff, or ‘safe-vs-useful’. People keep on going “why don’t we only use AIs to do X, that seems safe” and the answer is almost always either “doing X in fact takes very powerful cognition that is not passively safe” or, even more commonly, “because restricting yourself to doing X will not prevent Facebook AI Research from destroying the world six months later”. If all you need is an object that doesn’t do dangerous things, you could try a sponge; a sponge is very passively safe. Building a sponge, however, does not prevent Facebook AI Research from destroying the world six months later when they catch up to the leading actor.
**6**. **We need to align the performance of some large task, a ‘pivotal act’ that prevents other people from building an unaligned AGI that destroys the world.** While the number of actors with AGI is few or one, they must execute some “pivotal act”, strong enough to flip the gameboard, using an AGI powerful enough to do that. It’s not enough to be able to align a *weak* system – we need to align a system that can do some single *very large thing.* The example I usually give is “burn all GPUs”. This is not what I think you’d actually want to do with a powerful AGI – the nanomachines would need to operate in an incredibly complicated open environment to hunt down all the GPUs, and that would be needlessly difficult to align. However, all known pivotal acts are currently outside the Overton Window, and I expect them to stay there. So I picked an example where if anybody says “how dare you propose burning all GPUs?” I can say “Oh, well, I don’t *actually* advocate doing that; it’s just a mild overestimate for the rough power level of what you’d have to do, and the rough level of machine cognition required to do that, in order to prevent somebody else from destroying the world in six months or three years.” (If it wasn’t a mild overestimate, then ‘burn all GPUs’ would actually be the minimal pivotal task and hence correct answer, and I wouldn’t be able to give that denial.) Many clever-sounding proposals for alignment fall apart as soon as you ask “How could you use this to align a system that you could use to shut down all the GPUs in the world?” because it’s then clear that the system can’t do something that powerful, or, if it can do that, the system wouldn’t be easy to align. A GPU-burner is also a system powerful enough to, and purportedly authorized to, build nanotechnology, so it requires operating in a dangerous domain at a dangerous level of intelligence and capability; and this goes along with any non-fantasy attempt to name a way an AGI could change the world such that a half-dozen other would-be AGI-builders won’t destroy the world 6 months later.
**7**. The reason why nobody in this community has successfully named a ‘pivotal weak act’ where you do something weak enough with an AGI to be passively safe, but powerful enough to prevent any other AGI from destroying the world a year later – and yet also we can’t just go do that right now and need to wait on AI – is that *nothing like that exists*. There’s no reason why it should exist. There is not some elaborate clever reason why it exists but nobody can see it. It takes a lot of power to do something to the current world that prevents any other AGI from coming into existence; nothing which can do that is passively safe in virtue of its weakness. If you can’t solve the problem right now (which you can’t, because you’re opposed to other actors who don’t want to be solved and those actors are on roughly the same level as you) then you are resorting to some cognitive system that can do things you could not figure out how to do yourself, that you were not *close* to figuring out because you are not *close*to being able to, for example, burn all GPUs. Burning all GPUs would *actually* stop Facebook AI Research from destroying the world six months later; weaksauce Overton-abiding stuff about ‘improving public epistemology by setting GPT-4 loose on Twitter to provide scientifically literate arguments about everything’ will be cool but will not actually prevent Facebook AI Research from destroying the world six months later, or some eager open-source collaborative from destroying the world a year later if you manage to stop FAIR specifically. **There are no pivotal weak acts**.
**8**. **The best and easiest-found-by-optimization algorithms for solving problems we want an AI to solve, readily generalize to problems we’d rather the AI not solve**; you can’t build a system that only has the capability to drive red cars and not blue cars, because all red-car-driving algorithms generalize to the capability to drive blue cars.
**9**. The builders of a safe system, by hypothesis on such a thing being possible, would need to operate their system in a regime where it has the *capability*to kill everybody or make itself even more dangerous, but has been successfully designed to not do that. **Running AGIs doing something pivotal are not passively safe,** they’re the equivalent of nuclear cores that require actively maintained design properties to not go supercritical and melt down.
### Section B:
Okay, but as we all know, modern machine learning is like a genie where you just give it a wish, right? Expressed as some mysterious thing called a ‘loss function’, but which is basically just equivalent to an English wish phrasing, right? And then if you pour in enough computing power you get your wish, right? So why not train a giant stack of transformer layers on a dataset of agents doing nice things and not bad things, throw in the word ‘corrigibility’ somewhere, crank up that computing power, and get out an aligned AGI?
#### Section B.1: The distributional leap.
**10**. You can’t train alignment by running lethally dangerous cognitions, observing whether the outputs kill or deceive or corrupt the operators, assigning a loss, and doing supervised learning. **On anything like the standard ML paradigm, you would need to somehow generalize optimization-for-alignment you did in safe conditions, across a big distributional shift to dangerous conditions**. (Some generalization of this seems like it would have to be true even outside that paradigm; you wouldn’t be working on a live unaligned superintelligence to align it.) This alone is a point that is sufficient to kill a lot of naive proposals from people who never did or could concretely sketch out any specific scenario of what training they’d do, in order to align what output – which is why, of course, they never concretely sketch anything like that. **Powerful AGIs doing dangerous things that will kill you if misaligned, must have an alignment property that generalized far out-of-distribution from safer building/training operations that didn’t kill you.** This is where a huge amount of lethality comes from on anything remotely resembling the present paradigm. Unaligned operation at a dangerous level of intelligence\*capability will kill you; so, if you’re starting with an unaligned system and labeling outputs in order to get it to learn alignment, the training regime or building regime must be operating at some lower level of intelligence\*capability that is passively safe, where its currently-unaligned operation does not pose any threat. (Note that anything substantially smarter than you poses a threat given *any* realistic level of capability. Eg, “being able to produce outputs that humans look at” is probably sufficient for a generally much-smarter-than-human AGI to [navigate its way out of the causal systems that are humans](https://www.yudkowsky.net/singularity/aibox), especially in the real world where somebody trained the system on terabytes of Internet text, rather than somehow keeping it ignorant of the latent causes of its source code and training environments.)
**11**. If cognitive machinery doesn’t generalize far out of the distribution where you did tons of training, it can’t solve problems on the order of ‘build nanotechnology’ where it would be too expensive to run a million training runs of failing to build nanotechnology. There is no pivotal act this weak; **there’s no known case where you can entrain a safe level of ability on a safe environment where you can cheaply do millions of runs, and deploy that capability to save the world** and prevent the next AGI project up from destroying the world two years later. Pivotal weak acts like this aren’t known, and not for want of people looking for them. So, again, you end up needing alignment to generalize way out of the training distribution – not just because the training environment needs to be safe, but because the training environment probably also needs to be *cheaper* than evaluating some real-world domain in which the AGI needs to do some huge act. You don’t get 1000 failed tries at burning all GPUs – because people will notice, even leaving out the consequences of capabilities success and alignment failure.
**12**. **Operating at a highly intelligent level is a drastic shift in distribution from operating at a less intelligent level**, opening up new external options, and probably opening up even more new internal choices and modes. Problems that materialize at high intelligence and danger levels may fail to show up at safe lower levels of intelligence, or may recur after being suppressed by a first patch.
**13**. **Many alignment problems of superintelligence will not naturally appear at pre-dangerous, passively-safe levels of capability**. Consider the internal behavior ‘change your outer behavior to deliberately look more aligned and deceive the programmers, operators, and possibly any loss functions optimizing over you’. This problem is one that will appear at the superintelligent level; if, being otherwise ignorant, we guess that it is among the *median* such problems in terms of how *early* it naturally appears in earlier systems, then around *half* of the alignment problems of superintelligence will first naturally materialize *after*that one first starts to appear. Given *correct*foresight of which problems will naturally materialize *later,* one could try to deliberately materialize such problems earlier, and get in some observations of them. This helps to the extent (a) that we actually correctly forecast all of the problems that will appear later, or some superset of those; (b) that we succeed in preemptively materializing a superset of problems that will appear later; and (c) that we can actually solve, in the earlier laboratory that is out-of-distribution for us relative to the real problems, those alignment problems that would be lethal if we mishandle them when they materialize later. Anticipating *all*of the really dangerous ones, and then successfully materializing them, in the correct form for early solutions to generalize over to later solutions, *sounds possibly kinda hard*.
**14**. **Some problems**, like ‘the AGI has an option that (looks to it like) it could successfully kill and replace the programmers to fully optimize over its environment’, **seem like their natural order of appearance could be that they first appear only in fully dangerous domains**. Really actually having a *clear* option to brain-level-persuade the operators or escape onto the Internet, build nanotech, and destroy all of humanity – in a way where you’re fully clear that you know the relevant facts, and estimate only a not-worth-it low probability of learning something which changes your preferred strategy if you bide your time another month while further growing in capability – is an option that first gets evaluated for real at the point where an AGI fully expects it can defeat its creators. We can try to manifest an echo of that apparent scenario in earlier toy domains. Trying to train by gradient descent against that behavior, in that toy domain, is something I’d expect to produce not-particularly-coherent local patches to thought processes, which would break with near-certainty inside a superintelligence generalizing far outside the training distribution and thinking very different thoughts. Also, programmers and operators themselves, who are used to operating in not-fully-dangerous domains, are operating out-of-distribution when they enter into dangerous ones; our methodologies may at that time break.
**15**. **Fast capability gains seem likely, and may break lots of previous alignment-required invariants simultaneously.**Given otherwise insufficient foresight by the operators, I’d expect a lot of those problems to appear approximately simultaneously after a sharp capability gain. See, again, the case of human intelligence. We didn’t break alignment with the ‘inclusive reproductive fitness’ outer loss function, immediately after the introduction of farming – something like 40,000 years into a 50,000 year Cro-Magnon takeoff, as was itself running very quickly relative to the outer optimization loop of natural selection. Instead, we got a lot of technology more advanced than was in the ancestral environment, including contraception, in one very fast burst relative to the speed of the outer optimization loop, late in the general intelligence game. We started reflecting on ourselves a lot more, started being programmed a lot more by cultural evolution, and lots and lots of assumptions underlying our alignment in the ancestral training environment broke simultaneously. (People will perhaps rationalize reasons why this abstract description doesn’t carry over to gradient descent; eg, “gradient descent has less of an information bottleneck”. My model of this variety of reader has an inside view, which they will label an outside view, that assigns great relevance to some other data points that are *not* observed cases of an outer optimization loop producing an inner general intelligence, and assigns little importance to our one data point actually featuring the phenomenon in question. When an outer optimization loop actually produced general intelligence, it broke alignment after it turned general, and did so relatively late in the game of that general intelligence accumulating capability and knowledge, almost immediately before it turned ‘lethally’ dangerous relative to the outer optimization loop of natural selection. Consider skepticism, if someone is ignoring this one warning, especially if they are not presenting equally lethal and dangerous things that they say will go wrong instead.)
#### Section B.2: Central difficulties of outer and inner alignment.
**16**.Even if you train really hard on an exact loss function, that doesn’t thereby create an explicit internal representation of the loss function inside an AI that then continues to pursue that exact loss function in distribution-shifted environments. Humans don’t explicitly pursue inclusive genetic fitness; **outer optimization even on a very exact, very simple loss function doesn’t produce inner optimization in that direction**. This happens *in practice in real life,*it is what happened in *the only case we know about*, and it seems to me that there are deep theoretical reasons to expect it to happen again: the *first*semi-outer-aligned solutions found, in the search ordering of a real-world bounded optimization process, are not inner-aligned solutions. This is sufficient on its own, even ignoring many other items on this list, to trash entire categories of naive alignment proposals which assume that if you optimize a bunch on a loss function calculated using some simple concept, you get perfect inner alignment on that concept.
**17**. More generally, a superproblem of ‘outer optimization doesn’t produce inner alignment’ is that **on the current optimization paradigm there is no general idea of how to get particular inner properties into a system, or verify that they’re there, rather than just observable outer ones you can run a loss function over.** This is a problem when you’re trying to generalize out of the original training distribution, because, eg, the outer behaviors you see could have been produced by an inner-misaligned system that is deliberately producing outer behaviors that will fool you. We don’t know how to get any bits of information into the *inner* system rather than the *outer* behaviors, in any systematic or general way, on the current optimization paradigm.
**18**. **There’s no reliable Cartesian-sensory ground truth** (reliable loss-function-calculator) **about whether an output is ‘aligned’**, because some outputs destroy (or fool) the human operators and produce a different environmental causal chain behind the externally-registered loss function. That is, if you show an agent a reward signal that’s currently being generated by humans, the signal is not *in general* a *reliable perfect ground truth* about *how aligned an action was*, because another way of producing a high reward signal is to deceive, corrupt, or replace the human operators with a different causal system which generates that reward signal. When you show an agent an environmental reward signal, you are not showing it something that is a reliable ground truth about whether the system did the thing you wanted it to do; *even if* it ends up perfectly inner-aligned on that reward signal, or learning some concept that *exactly* corresponds to ‘wanting states of the environment which result in a high reward signal being sent’, an AGI strongly optimizing on that signal will kill you, because the sensory reward signal was not a ground truth about alignment (as seen by the operators).
**19**. More generally, **there is no known way to use the paradigm of loss functions, sensory inputs, and/or reward inputs, to optimize anything within a cognitive system to point at particular things within the environment** – to point to *latent events and objects and properties in the environment,* rather than *relatively shallow functions of the sense data and reward.* This isn’t to say that nothing in the system’s goal (whatever goal accidentally ends up being inner-optimized over) could ever point to anything in the environment by *accident*. Humans ended up pointing to their environments at least partially, though we’ve got lots of internally oriented motivational pointers as well. But insofar as the current paradigm works at all, the on-paper design properties say that it only works for aligning on known direct functions of sense data and reward functions. All of these kill you if optimized-over by a sufficiently powerful intelligence, because they imply strategies like ‘kill everyone in the world using nanotech to strike before they know they’re in a battle, and have control of your reward button forever after’. It just isn’t *true* that we know a function on webcam input such that every world with that webcam showing the right things is safe for us creatures outside the webcam. This general problem is a fact about the territory, not the map; it’s a fact about the actual environment, not the particular optimizer, that lethal-to-us possibilities exist in some possible environments underlying every given sense input.
**20**. Human operators are fallible, breakable, and manipulable. **Human raters make systematic errors – regular, compactly describable, predictable errors**. To *faithfully* learn a function from ‘human feedback’ is to learn (from our external standpoint) an unfaithful description of human preferences, with errors that are not random (from the outside standpoint of what we’d hoped to transfer). If you perfectly learn and perfectly maximize *the referent of* rewards assigned by human operators, that kills them. It’s a fact about the territory, not the map – about the environment, not the optimizer – that the *best predictive* explanation for human answers is one that predicts the systematic errors in our responses, and therefore is a psychological concept that correctly predicts the higher scores that would be assigned to human-error-producing cases.
**21**. There’s something like a single answer, or a single bucket of answers, for questions like ‘What’s the environment really like?’ and ‘How do I figure out the environment?’ and ‘Which of my possible outputs interact with reality in a way that causes reality to have certain properties?’, where a simple outer optimization loop will straightforwardly shove optimizees into this bucket. When you have a wrong belief, reality hits back at your wrong predictions. When you have a broken belief-updater, reality hits back at your broken predictive mechanism via predictive losses, and a gradient descent update fixes the problem in a simple way that can easily cohere with all the other predictive stuff. In contrast, when it comes to a choice of utility function, there are unbounded degrees of freedom and multiple reflectively coherent fixpoints. Reality doesn’t ‘hit back’ against things that are locally aligned with the loss function on a particular range of test cases, but globally misaligned on a wider range of test cases. This is the very abstract story about why hominids, once they finally started to generalize, generalized their *capabilities* to Moon landings, but their inner optimization no longer adhered very well to the outer-optimization goal of ‘relative inclusive reproductive fitness’ – even though they were in their ancestral environment optimized very strictly around this one thing and nothing else. This abstract dynamic is something you’d expect to be true about outer optimization loops on the order of both ‘natural selection’ and ‘gradient descent’. The central result: **Capabilities generalize further than alignment once capabilities start to generalize far**.
**22**. There’s a relatively simple core structure that explains why complicated cognitive machines work; which is why such a thing as general intelligence exists and not just a lot of unrelated special-purpose solutions; which is why capabilities generalize after outer optimization infuses them into something that has been optimized enough to become a powerful inner optimizer. The fact that this core structure is simple and relates generically to [low-entropy high-structure environments](https://intelligence.org/2017/12/06/chollet/) is why humans can walk on the Moon. **There is no analogous truth about there being a simple core of alignment**, especially not one that is *even easier* for gradient descent to find than it would have been for natural selection to just find ‘want inclusive reproductive fitness’ as a well-generalizing solution within ancestral humans. Therefore, capabilities generalize further out-of-distribution than alignment, once they start to generalize at all.
**23**. **Corrigibility is anti-natural to consequentialist reasoning**; “you can’t bring the coffee if you’re dead” for almost every kind of coffee. We (MIRI) [tried and failed](https://www.alignmentforum.org/posts/5bd75cc58225bf0670374f04/forum-digest-corrigibility-utility-indifference-and-related-control-ideas) to find a coherent formula for an agent that would let itself be shut down (without that agent actively trying to get shut down). Furthermore, many anti-corrigible lines of reasoning like this may only first appear at high levels of intelligence.
**24**. There are two fundamentally different approaches you can potentially take to alignment, which are unsolvable for two different sets of reasons; therefore, **by becoming confused and ambiguating between the two approaches, you can confuse yourself about whether alignment is necessarily difficult**. The first approach is to build a CEV-style Sovereign which wants exactly what we extrapolated-want and is therefore safe to let optimize all the future galaxies without it accepting any human input trying to stop it. The second course is to build corrigible AGI which doesn’t want exactly what we want, and yet somehow fails to kill us and take over the galaxies despite that being a convergent incentive there.
1. The first thing generally, or CEV specifically, is unworkable because **the complexity of what needs to be aligned or meta-aligned for our Real Actual Values is far out of reach for our FIRST TRY at AGI**. Yes I mean specifically that the *dataset, meta-learning algorithm, and what needs to be learned,* is far out of reach for our first try. It’s not just non-hand-codable, it is *unteachable*on-the-first-try because *the thing you are trying to teach is too weird and complicated.*
2. The second thing looks unworkable (less so than CEV, but still lethally unworkable) because **corrigibility runs*****actively counter*****to instrumentally convergent behaviors** within a core of general intelligence (the capability that generalizes far out of its original distribution). You’re not trying to make it have an opinion on something the core was previously neutral on. You’re trying to take a system implicitly trained on lots of arithmetic problems until its machinery started to reflect the common coherent core of arithmetic, and get it to say that as a special case 222 + 222 = 555. You can maybe train something to do this in a particular training distribution, but it’s incredibly likely to break when you present it with new math problems far outside that training distribution, on a system which successfully generalizes capabilities that far at all.
#### Section B.3: Central difficulties of *sufficiently good and useful* transparency / interpretability.
**25**. **We’ve got no idea what’s actually going on inside the giant inscrutable matrices and tensors of floating-point numbers**. Drawing interesting graphs of where a transformer layer is focusing attention doesn’t help if the question that needs answering is “So was it planning how to kill us or not?”
**26**. Even if we did know what was going on inside the giant inscrutable matrices while the AGI was still too weak to kill us, this would just result in us dying with more dignity, if DeepMind refused to run that system and let Facebook AI Research destroy the world two years later. **Knowing that a medium-strength system of inscrutable matrices is planning to kill us, does not thereby let us build a high-strength system of inscrutable matrices that isn’t planning to kill us**.
**27**. When you explicitly optimize against a detector of unaligned thoughts, you’re partially optimizing for more aligned thoughts, and partially optimizing for unaligned thoughts that are harder to detect. **Optimizing against an interpreted thought optimizes against interpretability**.
**28**. The AGI is smarter than us in whatever domain we’re trying to operate it inside, so we cannot mentally check all the possibilities it examines, and we cannot see all the consequences of its outputs using our own mental talent. **A powerful AI searches parts of the option space we don’t, and we can’t foresee all its options**.
**29**. The outputs of an AGI go through a huge, not-fully-known-to-us domain (the real world) before they have their real consequences. **Human beings cannot inspect an AGI’s output to determine whether the consequences will be good**.
**30**. Any pivotal act that is not something we can go do right now, will take advantage of the AGI figuring out things about the world we don’t know so that it can make plans we wouldn’t be able to make ourselves. It knows, at the least, the fact we didn’t previously know, that some action sequence results in the world we want. Then humans will not be competent to use their own knowledge of the world to figure out all the results of that action sequence. An AI whose action sequence you can fully understand all the effects of, before it executes, is much weaker than humans in that domain; you couldn’t make the same guarantee about an unaligned human as smart as yourself and trying to fool you. **There is no pivotal output of an AGI that is humanly checkable and can be used to safely save the world but only after checking it**; this is another form of pivotal weak act which does not exist.
**31**. A strategically aware intelligence can choose its visible outputs to have the consequence of deceiving you, including about such matters as whether the intelligence has acquired strategic awareness; **you can’t rely on behavioral inspection to determine facts about an AI which that AI might want to deceive you about**. (Including how smart it is, or whether it’s acquired strategic awareness.)
**32**. Human thought partially exposes only a partially scrutable outer surface layer. Words only trace our real thoughts. Words are not an AGI-complete data representation in its native style. The underparts of human thought are not exposed for direct imitation learning and can’t be put in any dataset. **This makes it hard and probably impossible to train a powerful system entirely on imitation of human words or other human-legible contents**, which are only impoverished subsystems of human thoughts; ***unless*****that system is powerful enough to contain inner intelligences figuring out the humans**, and at that point it is no longer really working as imitative human thought.
**33**. **The AI does not think like you do**, the AI doesn’t have thoughts built up from the same concepts you use, it is utterly alien on a staggering scale. Nobody knows what the hell GPT-3 is thinking, not *only* because the matrices are opaque, but because the *stuff within that opaque container*is, very likely, incredibly alien – nothing that would translate well into comprehensible human thinking, even if we could see past the giant wall of floating-point numbers to what lay behind.
#### Section B.4: Miscellaneous unworkable schemes.
**34**. **Coordination schemes between superintelligences are not things that humans can participate in** (eg because humans can’t reason reliably about the code of superintelligences); a “multipolar” system of 20 superintelligences with different utility functions, plus humanity, has a natural and obvious equilibrium which looks like “the 20 superintelligences cooperate with each other but not with humanity”.
**35**. Schemes for playing “different” AIs off against each other stop working if those AIs advance to the point of being able to coordinate via reasoning about (probability distributions over) each others’ code. **Any system of sufficiently intelligent agents can probably behave as a single agent, even if you imagine you’re playing them against each other.** Eg, if you set an AGI that is secretly a paperclip maximizer, to check the output of a nanosystems designer that is secretly a staples maximizer, then even if the nanosystems designer is not able to deduce what the paperclip maximizer really wants (namely paperclips), it could still logically commit to share half the universe with any agent checking its designs if those designs were allowed through, *if*the checker-agent can verify the suggester-system’s logical commitment and hence logically depend on it (which excludes human-level intelligences). Or, if you prefer simplified catastrophes without any logical decision theory, the suggester could bury in its nanosystem design the code for a new superintelligence that will visibly (to a superhuman checker) divide the universe between the nanosystem designer and the design-checker.
**36**. What makes an air conditioner ‘magic’ from the perspective of say the thirteenth century, is that even if you correctly show them the design of the air conditioner in advance, they won’t be able to understand from seeing that design why the air comes out cold; the design is exploiting regularities of the environment, rules of the world, laws of physics, that they don’t know about. The domain of human thought and human brains is very poorly understood by us, and exhibits phenomena like optical illusions, hypnosis, psychosis, mania, or simple afterimages produced by strong stimuli in one place leaving neural effects in another place. Maybe a superintelligence couldn’t defeat a human in a very simple realm like logical tic-tac-toe; if you’re fighting it in an incredibly complicated domain you understand poorly, like human minds, you should expect to be defeated by ‘magic’ in the sense that even if you saw its strategy you would not understand why that strategy worked. **AI-boxing can only work on relatively weak AGIs; the human operators are not secure systems**.
### Section C:
Okay, those are some significant problems, but lots of progress is being made on solving them, right? There’s a whole field calling itself “AI Safety” and many major organizations are expressing Very Grave Concern about how “safe” and “ethical” they are?
**37**. There’s a pattern that’s played out quite often, over all the times the Earth has spun around the Sun, in which some bright-eyed young scientist, young engineer, young entrepreneur, proceeds in full bright-eyed optimism to challenge some problem that turns out to be really quite difficult. Very often the cynical old veterans of the field try to warn them about this, and the bright-eyed youngsters don’t listen, because, like, who wants to hear about all that stuff, they want to go solve the problem! Then this person gets beaten about the head with a slipper by reality as they find out that their brilliant speculative theory is wrong, it’s actually really hard to build the thing because it keeps breaking, and society isn’t as eager to adopt their clever innovation as they might’ve hoped, in a process which eventually produces a new cynical old veteran. Which, if not literally optimal, is I suppose a nice life cycle to nod along to in a nature-show sort of way. Sometimes you do something for the *first* time and there *are* no cynical old veterans to warn anyone and people can be *really* optimistic about how it will go; eg the initial Dartmouth Summer Research Project on Artificial Intelligence in 1956: “An attempt will be made to find how to make machines use language, form abstractions and concepts, solve kinds of problems now reserved for humans, and improve themselves. We think that a significant advance can be made in one or more of these problems if a carefully selected group of scientists work on it together for a summer.” This is *less*of a viable survival plan for your *planet* if the first major failure of the bright-eyed youngsters kills *literally everyone* before they can predictably get beaten about the head with the news that there were all sorts of unforeseen difficulties and reasons why things were hard. You don’t get any cynical old veterans, in this case, because everybody on Earth is dead. Once you start to suspect you’re in that situation, you have to do the Bayesian thing and update now to the view you will predictably update to later: realize you’re in a situation of being that bright-eyed person who is going to encounter Unexpected Difficulties later and end up a cynical old veteran – or would be, except for the part where you’ll be dead along with everyone else. And become that cynical old veteran *right away,* before reality whaps you upside the head in the form of everybody dying and you not getting to learn. **Everyone else seems to feel that, so long as reality hasn’t whapped them upside the head yet and smacked them down with the actual difficulties, they’re free to go on living out the standard life-cycle and play out their role in the script and go on being bright-eyed youngsters; there’s no cynical old veterans to warn them otherwise, after all, and there’s no proof that everything won’t go beautifully easy and fine,*****given their bright-eyed total ignorance of what those later difficulties could be.***
**38**. **It does not appear to me that the field of ‘AI safety’ is currently being remotely productive on tackling its enormous lethal problems.** These problems are in fact out of reach; the contemporary field of AI safety has been selected to contain people who go to work in that field anyways. Almost all of them are there to tackle problems on which they can appear to succeed and publish a paper claiming success; if they can do that and get funded, why would they embark on a much more unpleasant project of trying something harder that they’ll fail at, just so the human species can die with marginally more dignity? This field is not making real progress and does not have a recognition function to distinguish real progress if it took place. You could pump a billion dollars into it and it would produce mostly noise to drown out what little progress was being made elsewhere.
**39**. **I figured this stuff out using the**[**null string**](https://twitter.com/ESYudkowsky/status/1500863629490544645)**as input,** and frankly, I have a hard time myself feeling hopeful about getting real alignment work out of somebody who previously sat around waiting for somebody else to input a persuasive argument into them. This ability to “notice lethal difficulties without Eliezer Yudkowsky arguing you into noticing them” currently is an opaque piece of cognitive machinery to me, I do not know how to train it into others. It probably relates to ‘[security mindset](https://intelligence.org/2017/11/25/security-mindset-ordinary-paranoia/)‘, and a mental motion where you refuse to play out scripts, and being able to operate in a field that’s in a state of chaos.
**40**. “Geniuses” with nice legible accomplishments in fields with tight feedback loops where it’s easy to determine which results are good or bad right away, and so validate that this person is a genius, are (a) people who might not be able to do equally great work away from tight feedback loops, (b) people who chose a field where their genius would be nicely legible even if that maybe wasn’t the place where humanity most needed a genius, and (c) probably don’t have the mysterious gears simply because they’re *rare.* **You cannot just pay $5 million apiece to a bunch of legible geniuses from other fields and expect to get great alignment work out of them.** They probably do not know where the real difficulties are, they probably do not understand what needs to be done, *they cannot tell the difference between good and bad work*, and the funders also can’t tell without me standing over their shoulders evaluating everything, which I do not have the physical stamina to do. I concede that real high-powered talents, especially if they’re still in their 20s, genuinely interested, and have done their reading, are people who, yeah, fine, have higher probabilities of making core contributions than a random bloke off the street. But I’d have more hope – not significant hope, but *more*hope – in separating the concerns of (a) credibly promising to pay big money retrospectively for good work to anyone who produces it, and (b) venturing prospective payments to somebody who is predicted to maybe produce good work later.
**41**. **Reading this document cannot make somebody a core alignment researcher**. That requires, not the ability to read this document and nod along with it, but the ability to spontaneously write it from scratch without anybody else prompting you; that is what makes somebody a peer of its author. It’s guaranteed that some of my analysis is mistaken, though not necessarily in a hopeful direction. The ability to do new basic work noticing and fixing those flaws is the same ability as the ability to write this document before I published it, which nobody apparently did, despite my having had other things to do than write this up for the last five years or so. Some of that silence may, possibly, optimistically, be due to nobody else in this field having the ability to write things comprehensibly – such that somebody out there had the knowledge to write all of this themselves, if they could only have written it up, but they couldn’t write, so didn’t try. I’m not particularly hopeful of this turning out to be true in real life, but I suppose it’s one possible place for a “positive model violation” (miracle). The fact that, twenty-one years into my entering this death game, seven years into other EAs noticing the death game, and two years into even normies starting to notice the death game, it is still Eliezer Yudkowsky writing up this list, says that humanity still has only one gamepiece that can do that. I knew I did not actually have the physical stamina to be a star researcher, I tried really really hard to replace myself before my health deteriorated further, and yet here I am writing this. That’s not what surviving worlds look like.
**42**. **There’s no plan.** Surviving worlds, by this point, and in fact several decades earlier, have a plan for how to survive. It is a written plan. The plan is not secret. In this non-surviving world, there are no candidate plans that do not immediately fall to Eliezer instantly pointing at the giant visible gaping holes in that plan. Or if you don’t know who Eliezer is, you don’t even realize you need a plan, because, like, how would a human being possibly realize that without Eliezer yelling at them? It’s not like people will yell at *themselves* about prospective alignment difficulties, they don’t have an *internal* voice of caution. So most organizations don’t have plans, because I haven’t taken the time to personally yell at them. ‘Maybe we should have a plan’ is deeper alignment mindset than they possess without me standing constantly on their shoulder as their personal angel pleading them into… continued noncompliance, in fact. Relatively few are aware even that they should, to look better, produce a *pretend* plan that can fool EAs too ‘[modest](https://equilibriabook.com/toc/)‘ to trust their own judgments about seemingly gaping holes in what serious-looking people apparently believe.
**43**. **This situation you see when you look around you is not what a surviving world looks like.** The worlds of humanity that survive have plans. They are not leaving to one tired guy with health problems the entire responsibility of pointing out real and lethal problems proactively. Key people are taking internal and real responsibility for finding flaws in their own plans, instead of considering it their job to propose solutions and somebody else’s job to prove those solutions wrong. That world started trying to solve their important lethal problems earlier than this. Half the people going into string theory shifted into AI alignment instead and made real progress there. When people suggest a planetarily-lethal problem that might materialize later – there’s a lot of people suggesting those, in the worlds destined to live, and they don’t have a special status in the field, it’s just what normal geniuses there do – they’re met with either solution plans or a reason why that shouldn’t happen, not an uncomfortable shrug and ‘How can you be sure that will happen’ / ‘There’s no way you could be sure of that now, we’ll have to wait on experimental evidence.’
A lot of those better worlds will die anyways. It’s a genuinely difficult problem, to solve something like that on your first try. But they’ll die with more dignity than this.

768f1b8e-94d2-4705-bc96-bd871f46ac3a | trentmkelly/LessWrong-43k | LessWrong | Biases: An Introduction
Imagine reaching into an urn that contains seventy white balls and thirty red ones, and plucking out ten mystery balls.
Perhaps three of the ten balls will be red, and you’ll correctly guess how many red balls total were in the urn. Or perhaps you’ll happen to grab four red balls, or some other number. Then you’ll probably get the total number wrong.
This random error is the cost of incomplete knowledge, and as errors go, it’s not so bad. Your estimates won’t be incorrect on average, and the more you learn, the smaller your error will tend to be.
On the other hand, suppose that the white balls are heavier, and sink to the bottom of the urn. Then your sample may be unrepresentative in a consistent direction.
That kind of error is called “statistical bias.” When your method of learning about the world is biased, learning more may not help. Acquiring more data can even consistently worsen a biased prediction.
If you’re used to holding knowledge and inquiry in high esteem, this is a scary prospect. If we want to be sure that learning more will help us, rather than making us worse off than we were before, we need to discover and correct for biases in our data.
The idea of cognitive bias in psychology works in an analogous way. A cognitive bias is a systematic error in how we think, as opposed to a random error or one that’s merely caused by our ignorance. Whereas statistical bias skews a sample so that it less closely resembles a larger population, cognitive biases skew our thinking so that it less accurately tracks the truth (or less reliably serves our other goals).
Maybe you have an optimism bias, and you find out that the red balls can be used to treat a rare tropical disease besetting your brother, and you end up overestimating how many red balls the urn contains because you wish the balls were mostly red.
Like statistical biases, cognitive biases can distort our view of reality, they can’t always be fixed by just gathering more data, and their effects can a |

d7766d8a-d31d-4676-8f23-779c45e04ffc | trentmkelly/LessWrong-43k | LessWrong | Stopping dangerous AI: Ideal US behavior
Disclaimer: this post doesn't have the answers. Moreover, it's an unfinished draft. Hopefully a future version will be valuable, but that will only occur if I revise/rewrite it. For now you're better off reading sources linked from AI policy ideas: Reading list and Slowing AI: Reading list.
Set aside most of AI safety to focus on the speed of AI progress. What should the US government do?[1] This post assumes that it's good to slow (dangerous) AI (especially near the end).
The ultimate goal is to prevent the deployment of powerful AI systems—that is, AI systems that would cause a catastrophe—until we learn how to make them safe. (Pretending alignment is monolithic.) You can do this by making powerful AI systems not developed, not deployed, or not cause a catastrophe if deployed because the world is super-resilient. Focusing on development is most promising.
So, delay the development of powerful AI systems until they're safe. (Probably that's too crude. Complications: (1) alignment progress is endogenous; (2) you have to actually pay the alignment tax so leading labs' lead time and safety-awareness are crucial.)
Lots of AI, like robotics and autonomous vehicles and some medical stuff and image generation and so forth, isn't very dangerous.
The dream would be that we have a test to determine whether an AI system would cause a catastrophe, and all large training runs are audited, and if a model fails the test then the training run is shut down. But (1) good tests don't exist yet, and (2) the only known way to make AI safe is to make it not powerful enough to cause a catastrophe.

A Cornell computer scientist recently wrote on social media:
> [...] I think the general sense in AI is that we don't know what will play out, but some of these possibilities are bad, and we need to start thinking about it. We are plagued by highly visible people ranging from Musk to Ng painting pictures ranging from imminent risk to highly premature needless fear, but that doesn't depict the center of gravity, which has noticeably shifted to thinking about the potential bad outcomes and what we might do about it. (Turning close to home to provide an example of how mainstream this is becoming, at Cornell two AI professors, Joe Halpern and Bart Selman, ran a seminar and course last semester on societal and ethical challenges for AI, and only just a few weeks ago we had a labor economist speak in our CS colloquium series about policy ideas targeting possible future directions for CS and AI, to an extremely large and enthusiastic audience.)

This is possibly surprising coming from the person who came up with [coherent extrapolated volition](https://arbital.com/p/cev/), co-wrote the *Cambridge Handbook of Artificial Intelligence* article on "[The Ethics of AI](https://intelligence.org/files/EthicsofAI.pdf)," etc. The relevant background comes from Eliezer's writing on the [minimality principle](https://arbital.com/p/minimality_principle/):
> [W]hen we are building the *first* [sufficiently advanced Artificial Intelligence](https://arbital.com/p/sufficiently_advanced_ai/), we are operating in an extremely dangerous context in which building a marginally more powerful AI is marginally more dangerous. The first AGI ever built should therefore execute the least dangerous plan for [preventing immediately following AGIs from destroying the world six months later](https://arbital.com/p/pivotal/). Furthermore, the least dangerous plan is not the plan that seems to contain the fewest material actions that seem risky in a conventional sense, but rather the plan that requires the *least dangerous cognition* from the AGI executing it. Similarly, inside the AGI itself, if a class of thought seems dangerous but necessary to execute sometimes, we want to execute the least instances of that class of thought required to accomplish the overall task.
>
> E.g., if we think it's a dangerous kind of event for the AGI to ask "How can I achieve this end using strategies from across every possible domain?" then we might want a design where most routine operations only search for strategies within a particular domain, and events where the AI searches across all known domains are rarer and visible to the programmers. Processing a goal that can recruit subgoals across every domain would be a dangerous event, albeit a necessary one, and therefore we want to do *less* of it within the AI."
>
>
So the technical task of figuring out how to build a robust minimal AGI system that's well-aligned with its operators' intentions is very different from "AI ethics"; and the tendency to conflate those two has plausibly caused a lot of thought and attention to go into much broader (or much narrower) issues that could have more profitably gone into thinking about the alignment problem.
One part of doing the absolute bare [world-saving minimum](http://www.danieldewey.net/fast-takeoff-strategies.html) with a general-purpose reasoning system is steering clear of any strategies that require the system to do significant moral reasoning (or implement less-than-totally-airtight moral views held by its operators). Just execute the most simple and straightforward concrete sequence of actions, requiring the least dangerous varieties and quantity of AGI cognition needed for success.
Another way of putting this view is that nearly all of the effort should be going into solving the technical problem, "How would you get an AI system to do some very modest [concrete action](https://arbital.com/p/task_goal/) requiring extremely high levels of intelligence, such as building two strawberries that are completely identical at the cellular level, without causing anything weird or disruptive to happen?"
Where obviously it's important that the system not do anything severely unethical in the process of building its strawberries; but if your strawberry-building system requires its developers to have a full understanding of meta-ethics or value aggregation in order to be safe and effective, then you've made some kind of catastrophic design mistake and should start over with a different approach. |

This paper says:

People mentally represent numbers as positions on a number line. I consider this a latent space representation. Human conceptual capabilities imply ability to at least average latent space representations, and possibly add them, which could then be used for fast approximation of sums. If only averaging is possible, then a 2-step (average -> double) process would be needed. The accuracy of that approach is insufficient for solving arithmetic problems, so people often instead use a much slower algorithm with exact accuracy.
Per the linked paper, 2nd-grade children have a tendency to place large numbers logarithmically, which implies to me an approximately logarithmic latent space representation. In that case, an accurate logarithmic representation should also be something humans are capable of with some training. In an accurate logarithmic representation, addition and subtraction are, of course, equivalent to multiplication and division.
Is it possible for people to do fast mental multiplications with the accuracy of a typical slide rule, by learning a logarithmic mental representation of numbers between 1 and 10? It seems plausible to me. Any big mental arithmetic fans around here?

This is an update on the work on AI Safety via Debate that we previously wrote about here.
Authors and Acknowledgements
The researchers on this project were Elizabeth Barnes and Paul Christiano, with substantial help from William Saunders (who built the current web interface as well as other help), Joe Collman (who helped develop the structured debate mechanisms), and Mark Xu, Chris Painter, Mihnea Maftei and Ronny Fernandez (who took part in many debates as well as helping think through problems). We're also grateful to Geoffrey Irving and Evan Hubinger for feedback on drafts, and for helpful conversations, along with Richard Ngo, Daniel Ziegler, John Schulman, Amanda Askell and Jeff Wu. Finally, we're grateful to our contractors who participated in experiments, including Adam Scherlis, Kevin Liu, Rohan Kapoor and Kunal Sharda.
What we did
We tested the debate protocol introduced in AI Safety via Debate with human judges and debaters. We found various problems and improved the mechanism to fix these issues (details of these are in the appendix). However, we discovered that a dishonest debater can often create arguments that have a fatal error, but where it is very hard to locate the error. We don’t have a fix for this “obfuscated argument” problem, and believe it might be an important quantitative limitation for both IDA and Debate.
Key takeaways and relevance for alignment
Our ultimate goal is to find a mechanism that allows us to learn anything that a machine learning model knows: if the model can efficiently find the correct answer to some problem, our mechanism should favor the correct answer while only requiring a tractable number of human judgements and a reasonable number of computation steps for the model. [1]
We’re working under a hypothesis that there are broadly two ways to know things: via step-by-step reasoning about implications (logic, computation…), and by learning and generalizing from data (pattern matching, bayesian updating…).

Long story short, it's an attempt to justify the planetarium hypothesis as a solution to the Fermi paradox. The first half is a discussion of how it and things like it are relevant to the intended purview of the blog, and the second half is the meat of the post. You'll probably want to just eat the meat, which I think is relevant to the interests of many LessWrong folk.
The blog is Computational Theology. It's new. I'll be the primary poster, but others are sought. I'll likely introduce the blog and more completely describe it in its own discussion post when more posts are up, hopefully including a few from people besides me, and when the archive will give a more informative indication of what to expect from the blog. Despite theism's suspect reputation here at LessWrong I suspect many of the future posts will be of interest to this audience anyway, especially for those of you who take interest in discussion of the singularity. The blog will even occasionally touch on rationality proper. So you might want to store the fact of the blog's existence somewhere deep in the back of your head.

I'd appreciate it if comments about the substance of the post were made on the blog post itself, but if you want to discuss the content here on LessWrong then that's okay too. Any meta-level comments about presentation, typos, or the post's relevance to LessWrong, should probably be put as comments on this discussion post. Thanks all! |

1Formal Definition of AI
Dimiter Dobrev
dobrev@2-box.net
18 October, 2005
Abstract
A definition of Artificial Intelligence was propose d in [1] but this definition was not
absolutely formal at least because the word "Human" was used. In this paper we will
formalize the definition from [1]. The biggest prob lem in this definition was that the level
of intelligence of AI is compared to the intelligen ce of a human being. In order to change
this we will introduce some parameters to which AI will depend. One of this parameters
will be the level of intelligence and we will defin e one AI to each level of intelligence. We
assume that for some level of intelligence the resp ective AI will be more intelligent than a
human being. Nevertheless, we cannot say which is t his level because we cannot calculate
its exact value.
Introduction
The definition in [1] first was published in popula r form in [2, 3]. It was stated in one
sentence but with many assumptions and explanations which were given before and after
this sentence. Here is the definition of AI in one sentence:
AI will be such a program which in an arbitrary wor ld will cope no worse than a
human.
From this sentence you can see that we assume that AI is a program. Also, we assume that
AI is a step device and that on every step it input s from outside a portion of information (a
letter from finite alphabet Σ) and outputs a portion of information (a letter fr om a finite
alphabet Ω). The third assumption is that AI is in some envir onment which gives it a
portion of information on every step and which rece ives the output of AI. Also, we
assume that this environment will be influenced of the information which AI outputs. This
environment can be natural or artificial and we wil l refer to it as "World".
The World will be: one set S, one element s 0 of S and two functions World(s, d) and
View(s). The set S contains the internal states of the world and it can be finite or infinite.
The element s 0 of S will be the world's starting state. The funct ion World will take as
arguments the current state of the world and the in fluence that our device exerts on the
world at the current step. As a result, this functi on will return the new state of the world
(which it will obtain on the next step). The functi on View gives the information what our
2device sees. An argument of this function will be t he world's current state and the returned
value will be the information that the device will receive (at a given step).
Life in one world will be any infinite row of the t ype: d 1, v 1, d 2, v 2, ... where v i are letters
from Σ and d i are letters from Ω. Also, there has to exist infinite row s 0, s 1, s 2, ... such that
s0 is the staring state of the world and ∀i>0 vi=View(s i) and ∀i s i+1 =World(s i, d i+1 ). It is
obvious that if the world is given then the life de pends only on the actions of AI (i.e.
depends only on the row d 1, d 2, d 3, ...).
In order to transform the definition in [1] and to make it formal, we have to define what is
a program, what is a good world and when one life i s better than another.
The first task is easy because this work is done by Turing in the main part. Anyway, the
Turing definition of program is for a program which represents function, but here we need
a transducer which inputs the row v 1, v 2, v 3, ... and outputs the row d 1, d 2, d 3, ... . So, we
will make a modification of the definition of Turin g machine [9].
Our second task is to say what is a good world. It was written in [1] that if you can make
a fatal error in one world then this world is not g ood. What is world without fatal errors
needs additional formalization.
The next problem is to say when one life is better than another. This is done in [1] but
there are some problems connected with the infinity which have to be fixed.
The last task is to say how intelligent our program should be and this cannot be done by
comparison with a human being.
What is a program
We will define a program as a Turing machine [9]. L et its alphabet Δ consist of the letters
from Σ, from Ω, from one blank symbol λ and from some service signs.
Let our Turing machine have finite set of internal states P, one starting state p 0 and a
partial function F : P × Δ → P × Δ × {Left, Right}.
The Turing machine (TM) is a step device and it mak es steps in order to do calculations.
On the other hand, AI is a step device and its life consists of steps. In order to make
distinction between these two types of steps we wil l call them small and big steps. When
we speak about time we will mean the number of big steps.
Of course, our TM will start from the state p 0 with infinite tape filled with the blank
symbol λ. How our TM will make one small step. If it is in state p and if its head looks at
the letter δ then F(p, δ) will be a 3-tuple which first element is the new state after the small
3step, the second element will be the new letter whi ch will replace δ on the tape and the
third element will be direction in which the head w ill move.
How will our TM (which is also our AI) make one big step? This will happen when after a
small step the new state of TM is again p 0. At this moment our TM has to output one
letter d i and to input one letter v i. We will assume that the letter which is outputted is that
which is written on the place of δ on this small step. But how after outputting the l etter d i
will our TM input the letter v i? We will put this letter on the place where the he ad after the
small step is. In this way we are intervening in th e work of the TM by replacing one
symbol from the tape with another. The replaced sym bol is lost in some sense because it
will not influence the execution of the TM from thi s small step on.
We will assume that our TM is outputting only lette rs from Ω (no letters from the rest of
Δ). Also, we assume that our TM never hangs. TM hang s if after reading some input v 1,
v2, ... , v n it stops because it falls into some state p and it s head falls on some letter δ such
that F(p, δ) is not defined. TM also hangs if after reading of some input v 1, v 2, ... , v n it
makes infinitely many small steps without reaching the state p 0 (without making of big
steps anymore).
After this we have a formal definition of a program . We have to mention that there is no
restriction on the number of the small steps which TM needs to make for one big step.
This number has to be finite but it is not restrict ed. Maybe it is a good idea to add one
parameter Max_number_of_small_steps_in_AI in order to exclude some decisions for AI
which are combinatory explosions. (If we restrict t he number of small steps then we have
to restrict also the number of service signs in Δ because we can speed up the TM by
increasing the size of its alphabet.) If we want to use AI as a real program on a real
computer then we have to take into consideration th at the memory of the real computers is
limited. So, we can restrict also the size of the t ape. Anyway, we will not care about the
efficiency of AI and we will not make such restrict ions.
What is a world without fatal errors
It is very difficult to define what is a world with out fatal errors. That is why we will do
something else. We will restrict our set of worlds is such a way that the new set will
contain only worlds without fatal errors.
Let our world look like one infinite sequence of ga mes. Let every game be independent
from the previous ones. Let us have three special l etters in Σ, which we will call final
letters. Let this letters be {victory, loss, draw}. Let every game finish with one of the final
letters. Let every game be shorter than 1000 big st eps.
Remark 1 : Our definition of AI will depend on many paramete rs. In order to simplify the
exposition we will fix these parameters to concrete numbers. Such parameter is the
4maximum number of steps in a game which will be fix ed to 1000. Also, in order to
simplify the exposition we will use different numbe rs for different parameters.
Remark 2 : The only parameters in our definition which are n ot numbers are the alphabets
Σ and Ω. We will assume that these alphabets are fixed and that Ω has at least 2 letters
and Σ has at least 2 letters which are not final. (If Ω has only one letter then there will be
no choice for the action of AI and the world will b e independent from this action. If Σ has
only one letter, which is not final, then the game will be blind because AI will not receive
any information until the end of the game. Therefor e, the minimum for | Σ| is 5.)
We will assume that the world has three special int ernal states {s_victory, s_loss, s_draw},
which we will call final states. Let these states b e indistinguishable from the state s 0 for the
function World. This means that the world will beha ve in the final states in the same way
as if it was in the starting state. Let the functio n View distinguish the final states and
return from them the letters victory, loss and draw respectively. Also, the final states will
be the only states on which the function View will return one of the letters {victory, loss,
draw}.
After the restriction of the definition of World, w e can be sure that there are no fatal
errors in our world because the life in such a worl d is an infinite sequence of games and if
we lose some games (finitely many) then this will n ot be fatal because every new game is
independent from the previous ones. Also, we are su re that a new game will come sooner
or later because every game is finite (i.e. previou s game is shorter than 1000 steps).
When is one life better than another
In [1] we gave the following definition for the mea ning of the life: One life is better than
another if it includes more good letters and fewer bad letters. Here good letters will be
{victory, draw} and bad letters will be {loss, draw }. So, here life is good if we win often
and lose seldom.
We want to introduce one function Success which wil l evaluate with a real number every
life in order to say how good it is. For that we wi ll define first the function Success for the
every beginning of life (all beginnings are finite) . After that we will calculate the limit of
Success when the size of the beginnings goes to inf inity and this limit will be the value of
Success for the entire life.
The function Success can be defined for the beginni ngs like the difference between the
number of victories and the number of losses. This is not a good idea because then the
limit of Success will possibly converge to infinity (plus or minus infinity). It is a better idea
to calculate the percentage of victories. So, we de fine Success as (2.N_victory +N_draw)/
(2.N_games). Here N_victory is the number of victor ies (analogically for N_draw and
N_games). Function Success will give us a number be tween 0 and 1 for every beginning
5and its limit will be also between 0 and 1. The onl y problem is that Success may not have a
limit. In such a case we will use the average betwe en limit inferior and limit superior.
Trivial decisions
Now we have a really formal definition of AI and th is gives us the first trivial decision for
AI.
TD1 will be the program which plays at random until the first victory. After that TD1
repeats this victory forever. For this TD1 needs on ly to remember what it did in the last
game. If the last game was victorious then it can r epeat this last game because the function
World is deterministic and if TD1 is doing the same then the world will do the same too.
TD1 is perfect in all worlds in which the victory i s possible. If the victory is not possible
then TD1 will play at random forever. That is why w e will make TD2 which will be
perfect in all worlds.
TD2 will be this program which tries sequentially a ll possible game's strategies until it
finds the first victory and after that repeats this victory forever. If there is no victorious
game strategy then TD2 repeats the last draw game f orever. If the draw game is not
possible too then TD2 plays at random. (It is impor tant that the game's length is not more
than 1000. This means that the number of the game's strategies is finite.)
TD2 is perfect in all worlds and this means that it is a trivial decision on our definition for
AI. Really, the definition stated that AI has to co pe no worse than a human but for the
perfect program this is true because it copes no wo rse than anything even no worse than a
human being.
It is suspicious that such simple program like TD2 can satisfy our definition for AI. That is
why we will change the definition by accepting more possible worlds. It is too restrictive
to assume that the game is deterministic and every time you do the same the same will
happen.
Nondeterministic games
We will assume that the function World is not deter ministic. It is better to say that it is
multy-valued function, which chooses at random one of its possible values. Let every
possible value correspond to one real number, which is the possibility for this value to be
chosen. We will assume also that ∀s ∀ω World(s, ω) has at least one value and that ∀s
∀ω (for every two different values of World(s, ω) the function View returns different
result).
6Remark 3 : The latter means that if something nondeterminist ic happens this information
will be given to AI immediately by the function Vie w. There is no sense to assume
existence of a nondeterministic change which cannot be detected immediately but later or
even which cannot be detected never.
Now we will ask the question what is the best strat egy in such a world and we will offer a
program, which will be almost perfect. Before that we need several definitions:
Definition 1: Tree of any game. It will have two types of vertices. The root and t he
other vertices which are on even depth will be the vertices of type AI (because they
correspond to the moments when AI has to do its cho ice). The vertices which are on odd
depth will be vertices of the type world (because t hey correspond to the moments when
the world will answer at random). From the vertices of type AI go out | Ω| arcs and to
every such arc corresponds one of the letters from Ω. There is one exception. If the arc
which is right before this vertex corresponds to a final letter, then this vertex is a leaf.
From the vertices of type world go out | Σ| arcs and to every such arc corresponds one of
the letters from Σ. Here there is an exception again. If this vertex is on depth 1999, then
only three arcs go out and these three arcs corresp ond to the final letters.
You can see that the tree of any game is finite and its maximum depth is 2000 (because
games are not longer than 1000 steps). Nevertheless , there are leaves on any even depth
between 2 and 2000.
Definition 2: Tree of any 100 games. Let us take the tree of any game. Let us replace a ll
of its leaves with the tree on any game. Let us rep eat this operation 99 times. The result
will be the tree of any 100 games (which is 100 tim es deeper than the tree of any game).
From the tree of any game we will receive Strategy for any game. This will be its subtree
which is obtained by choosing one vertex from the s uccessors of every vertex of the type
AI and deleting the rest successors (and their subt rees). Analogically we make Strategy for
any 100 games like a subtree from the tree of any 1 00 games. We have to mention that the
strategy for 100 games can be different from repeat ing one Strategy for any game 100
times. The reason is because the strategy on the ne xt game can depend on the previous
games.
Definition 3: Tree of this game. For every concrete game (i.e. concrete world) we c an
construct the tree of this game as a subtree from t he tree of any game. We will juxtapose
internal states of the world to the vertices of typ e AI in the time of this construction. First,
we will juxtapose the state s 0 to the root. Let k 0, k 1 and k 2 be vertices and let k 1 be
successor of k 0 and k 2 be successor of k 1. Let k 0 be vertex of type AI and let the state s be
juxtaposed to it. Let the letters ω and ε be juxtaposed to the arcs <k 0, k 1> and <k 1, k 2>. In
this case if ε ≠ View(World(s, ω)) for every value of World(s, ω) then we delete the vertex
k2 (and its subtree). In the opposite case we juxtapo se k 2 to this value of World(s, ω) for
which ε = View(World(s, ω)). This value is only (look at remark 3). Also, we will
7juxtapose the possibility ε to be the value of View(World(s, ω)) to the arc <k 1, k 2>. So,
one letter and one possibility will be juxtaposed t o the arc <k 1, k 2>.
Analogically to the strategy for any game we can ma ke strategy for this game. We have to
say that if the World is deterministic (i.e. every vertex of type world has only one
successor) then the strategy for this game is a pat h (a tree without branches). In this case
the paths in the tree of this game are exactly the strategies for this game. This was used
from TD2 in order to try all strategies.
Max-Sum algorithm
For every vertex of the tree of this game we can ca lculate the best possible success (this is
our expectation for success, if we play with the be st strategy from that vertex on).
1. The best possible success for the leaves will be 1, 0 and 1/2 for the states s_victory,
s_loss and s_draw respectively.
2. If the vertex is of type AI, then its best possi ble success will be the maximum from the
best possible successes of its successors.
3. If the vertex is of type world, then its best po ssible success will be the sum
Σ Possibility(i). BestPossibleSuccess(i). Here i runs through all successors of this vertex.
The algorithm for calculating the best possible suc cess can also be used to calculate the
best strategy in this game (the best strategy can b e more than one). This algorithm looks
like the Min-Max algorithm, which we use in chess. Anyway, this is different algorithm, to
which we will refer as Max-Sum algorithm. The diffe rence is essential because in the chess
we assume that we play against someone who will do the worst thing to us (remark 4).
Anyway, in the arbitrary world we cannot assume tha t the world is against us. For
example, when you go to work you go first to the pa rking lot in order to take your car. If
your car is stolen, then you go to the bus stop in order to take the bus. If every time you
were presumed the worst case, then you would go dir ectly to the bus stop.
New trivial decisions
Now we can calculate the best possible success for any game and we will give the next
trivial decision (TD3), which will do the best in e very game. This means that the success
of TD3 for one world will be equal to its best poss ible success.
TD3 will be the program which plays at random for l ong time enough. In this time TD3
collects statistical information for the tree of th is game and builds inside its memory this
tree together with the values of all possibilities. After that time TD3 starts playing by the
use of Max-Sum algorithm.
8TD3 gives the perfect decision in any world but TD3 is impossible because we cannot say
when enough statistical information is selected. An yway, possible is something which is a
little bit worse. For every ε > 0 we will make TD4, which for every world will m ake
success on a distance no more than ε from the best possible.
TD4 will be this program which simultaneously colle cts statistical information for the tree
of this game and in the same time plays by the use of Max-Sum algorithm on the base of
statistics, which is collected up to the current mo ment. In order to collect statistics TD4
makes experiments which contradict to the recommend ations of Max-Sum algorithm.
Such experiments are made rarely enough to have suc cess on a distance not bigger than ε
from the best possible success.
We can choose the value of ε to be as small as we want. Anyway, the price for t he small
value of ε is the longer time for education (because of rare experiments). We will call the
parameter ε "courage". Here we receive a surprising conclusion that if AI is more
cowardly it is closer to perfection (this is true o nly in the case of infinite life).
TD4 is a decision for our definition of AI because it is only on ε distance to perfection
unlike the people who are much farther from perfect ion. We have to mention that in some
sense TD4 is not as trivial as TD2, because TD4 rep resents awful combinatory explosion
in the execution time (number of small steps) and i n the memory size. Anyway, we said
that we will not care about the efficiency of AI fo r the moment. On the other hand, there is
one additional problem, which is present in both TD 2 and TD4, and which makes them
both useless. This is the problem of the combinator y explosion of the educational time.
Imagine that you are playing chess at random agains t deterministic partner. How long will
you need to make accidental victory? Or in case you r partner is not deterministic. How
long will you need to play all possible game's stra tegies and try each one several times in
order to collect statistical information on how you r partner reacts in every case?
Finite life
In some sense TD2 and TD4 are extremely stupid beca use they need extremely long time
for education. Really, educational time and level o f intelligence are two different
parameters of the mind and if one of them is better then this can be at the expense of the
other. For example, a human being needs about a yea r to learn to walk, which is much
worse in comparison to most animals. Some of the gr eatest scientists had bad results in
school, which can be interpreted as a fact that the y advanced slower than the ordinary
people.
Therefore, the educational time is important and it has to be limited in order to make our
definition useful. This will be done by changing th e life length from infinite to finite. We
will assume that the length of the life is 100 game s. Each game has maximum 1000 steps,
which means that the life length is not bigger than 10,000 steps. Now the success of the
9life will not be the limit of the Success function but the value of this function for the first
100 games.
After this we can look for program which makes a go od success in an arbitrary world, but
this is not a good idea because the arbitrary world is too unpredictable. Human beings use
the assumption that the world is simple and that is why they cope very well in a more
simple environment and they are totally confused if the environment is too complicated.
Therefore, we have to restrict the complexity of th e world and give bigger importance to
the more simple worlds. For this restriction we wil l use Kolmogorov Complexity [8]. The
parameter which restricts the complexity of the wor ld will be the level of intelligence of
AI.
Kolmogorov Complexity
First we need a definition of program which calcula tes the functions World and View. For
this we will use the same definition of TM as for t he program which was our AI. There
will be some small differences: The alphabet of the Turing Machine of the world (TM_W)
will be Σ ∪ Ω ∪ { λ} (the only service symbol will be λ). Also, TM_W will input the row
d1, d 2, d 3, ... and output the row v 1, v 2, v 3, ... . At the beginning TM_W will start with tape
on which d 1 is at the head position and the rest is λ. At the end of the first big step TM_W
will output v 1 and input d 2. F will be set of 5-tuples which is a subset to P × Δ × P × Δ ×
{Left, Right}. This means that F is not a function but a relation (because it will represent
multy-valued function). We will assume that ∀s ∀δ ∃5-tuple ∈F whose first two elements
are s and δ (this makes the reasons for hanging with one less) . The 5-tuples in F whose
third element is p 0 will be called output 5-tuples. The fourth element of output 5-tuples
has to be letter from Σ (this is not necessary but sufficient condition in order TM_W to
output only letters from Σ). We will allow nondeterministic behavior only for output 5-
tuples. This means that if two different 5-tuples h ave the same first and second elements
then they both have to be output 5-tuples. There wi ll be no two 5-tuples which differ only
at the fifth element (we cannot have a choice betwe en two nondeterministic 5-tuples which
output the same letter - look again at remark 3). I t will be more interesting if we assume
that nondeterministic 5-tuples have additional para meter which shows the possibility for
each of them to be chosen. Nevertheless, we will as sume that this possibility is distributed
equally and that we do not have such additional par ameter.
According to this definition, the internal states o f the world will be the states of the tape of
the TM_W. If we want to have worlds without fatal e rrors we have to clean the tape of
TM_W after each game (after printing any final lett er). Nevertheless, we will not do this
because the absence of fatal errors was important w hen we had infinite life and when we
counted on that sooner or later all errors will be compensated. For real AI is better to
assume some connection between games. Otherwise AI will not remember what was done
in the last game or it will remember it but it will not know whether this was in the last
game or in some other game from the previous ones.
10 Another question is what we will do with TM_W which hangs. We do not want to exclude
these programs from our definition (at least becaus e we cannot check this characteristic).
That is why we will assume that if one TM_W makes m ore than 800 small steps without
making a big step then we will interrupt it with ou tput "draw". This means that it will do
the next small step in the same way as if the 5-tup le executed at this moment had third
element p 0 and fourth element "draw". Also, if one TM_W makes 1000 big steps without
outputting any final symbol then the output of the next big step will be "draw". We need
this in order to keep the games finite, which is im portant in order to keep the life finite
(the life is 100 games).
We will define the size of TM_W as the number of in ternal states plus the level of
indefiniteness (this is the minimal number of nonde terministic 5-tuples, which have to be
deleted from F in order to make it deterministic or this is the number of all
nondeterministic 5-tuples minus the number of diffe rent groups of nondeterministic 5-
tuples).
So, we will restrict the set of possible worlds to those generated by Turing Machine
whose size is not bigger than 20. The maximum size of the TM_W will be the level of
intelligence of AI. The simpler worlds will be more important because they are generated
from more than one TM_W and that is why we will cou nt their result more than once.
Remark 4 : It looks like that two Turing machines (the world and AI) play against each
other. Anyway, this is wrong because the world does not care about AI and it dose not
play against AI.
Final definition of AI
Now everything is fixed. We have finite lives, whic h are exactly 100 games. We had
selected the success function that will evaluate th ese lives. Also, we made a finite set of
worlds which consist of the worlds generated from t he TM_W with size not bigger than
20. Now we can define AI as this program which will make the best average success in the
selected worlds. Such program exists and it will be the next trivial decision (TD5).
The number of all strategies for playing 100 consec utive games is finite. The number of
selected worlds is also finite. We can calculate th e expected success of any strategy in any
world. The average success of a strategy will be th e arithmetical mean from its expected
success in any world. (The calculation of the expec ted success of a strategy in a world is
easy if the world is deterministic. In this case, w e will have simply to play 100 games with
this strategy in this world. In the opposite case, if the world is nondeterministic then we
have to use Max-Sum algorithm, which is theoretical ly possible, but in practice it is a
combinatory explosion. Nevertheless, even if the wo rlds were only deterministic, we
would have combinatory explosion again from the num ber of worlds and from the number
of strategies.)
11 Hence, TD5 will be this program which calculates an d plays the best strategy (this which
average success is biggest). Such program is easy t o be written but it is very difficult to
wait until it makes its first step. The situation w ith the perfect chess playing program is
analogical. (It plays chess by calculating all poss ible moves.) This program can be written
very easy but the time until the end of the univers e will be not enough for it to make its
first move.
It will be too restrictive if we define AI as the b est program (such as TD5 or such as any
other program equivalent to TD5). It will be better if we say that AI is a program whose
average success is not more than 10% from the best (from TD5) (when we say 1% we
mean the number 0.01) (the distance to the best is something completely different from the
parameter "courage" in TD2). Such definition is the oretically possible, but practically
inconvenient. The reason for this is the fact that the value of the average success of TD5
can be theoretically calculated, but in practice th is is absolutely impossible. So, if we select
such definition we will not be able to check it for a concrete program.
Final definition: AI will be a program which makes more than 70% aver age success in
the selected set of worlds.
Assumption 1 : Here we assume that the average success of TD5 is about 80%. If this
conjecture is true then there exists a program whic h satisfies the definition (at least TD5
do). If the average success of TD5 is smaller than 70% then there is no such a program (of
course, in such case we can change this parameter a nd make it smaller than 70%).
The advantage of this definition of AI is that we c an check it for a concrete program. Of
course, we cannot calculate the average success for any program due to the combinatory
explosion, but we can calculate it approximately by the methods of the statistics. How we
will do this. We will select at random N worlds (wo rld is TM_W with size not bigger than
20) and we will play 100 consecutive games in every world. If the world is deterministic
then this will give us the expected success of our program in this world. If it is not
deterministic then we will play at random in this w orld. This will give us statistically good
evaluation of the expected success because the poss ibility to be extremely lucky in 100
games is very small (so is the possibility to be ex tremely unlucky). If N (the number of the
tested worlds) is big then the statistical result w ill be close to the average success of our
program.
If |Σ ∪ Ω ∪ { λ}| = 5 (which is the minimum - remark 2) then the n umber of deterministic
TM_W with 20 states is 200 on power of 100. If we t ake the number of nondeterministic
TM_W with 19 states and level of indefiniteness one (which means with two
nondeterministic 5-tuples) then this number is many times smaller than 200 on power of
100. In order to use the method of statistics we ha ve to calculate how many times is this
number smaller. Otherwise we will use wrong correla tion between deterministic and
nondeterministic TM_W. Anyway, such wrong correlati on will make an unessential
change in the definition of AI.
12 Conclusion
Now we have definition of AI and at least one progr am (TD5) which satisfies it (with
assumption 1). The first question is: Does this def inition satisfy our intuitive idea that AI is
a program which is more intelligent than a human be ing. Yes, but for some values of the
parameters educational time and level of intelligen ce. In this paper the educational time
was fixed on 100 games each of them no longer than 1000 steps (educational time is equal
to the life length because we learn all our life). The level of intelligence here was fixed on
20. Which means that we assume that we can find a m odel of the world which is TM_W
with size not bigger than 20. We cannot say what is the exact level of intelligence of the
human being.
The second question is: Is TD5 which satisfies the definition the program which we are
looking for. The answer is definitely no. We are lo oking for a program which can work in
real time. Also, our intuitive idea is that AI shou ld build a model of the world and on the
base of it AI should plan its behavior. Look at [6, 7]. Instead of this, TD5 uses brutal
force in order to find the best strategy. Even TD5 will not know what to do on the game
101 because its strategy is only for 100 games.
Here we will offer the last trivial decision (TD6), which corresponds better to our intuitive
idea for AI.
Let TD6 be the program which tries all deterministi c TM_W and accepts as a model of the
world the first one (the shortest one) which genera tes the life until the present moment.
After selecting a model (which will be a big proble m for more complicated worlds) TD6
will use this model and the Max-Sum algorithm in or der to plan its next move. Here the
Max-Sum algorithm has two modifications: First, the re is no Sum (or there is only one
term in the sum) because the modeling TM_W is deter ministic and there is only one
possible reaction from the world. Second modificati on is that Max-Sum will not calculate
until the end of the life or even until the end of the game because this will give a
combinatory explosion. Instead, it will calculate s everal steps like chess playing programs
do.
You can find a program similar to TD6 in [5]. Reall y, in [5] we are looking for TM_W,
which is a generator of infinite sequence v 1, v 2, v 3, ... instead of looking for transducer
from d 1, d 2, d 3, ... to v 1, v 2, v 3, ... . Also, [5] does not make moves (there is no Max-Sum
algorithm for calculating the next move). The only thing which [5] does is to predict the
next number of the sequence. Anyway, in [5] you can see that searching for a model in the
set of all TM_W works only if the model is very sim ple. If the size of TM_W is bigger
than 5, the result is combinatory explosion.
If we modify TD6 in order to accept also the nondet erministic Turing machines as models
of the world then we will have too much possible mo dels. In this case we have to consider
more than one model and to evaluate each possible m odel in order to see how reliable it is.
13 Anyway, TD6 and its modifications are not the progr am which we are looking for,
although TD6 can be done to satisfy the definition (because the definition does not say
anything about the efficiency of AI). The program w hich we are looking for is much closer
to that one which is described in [6, 7]. The probl em in TD6 is that it looks for a model of
the world which consists from only one item. It is better if the model is a set of many items
(the items can be Turing machines, final automata o r logical formulas). When we make a
theory in logic then it consist from a set of axiom s and we can change smoothly the theory
by modifying, adding or deleting one axiom. Any the ory in logic is a model of some world.
AI has to use similar models which can be modified smoothly.

This story is reposted from nonzerosum.games where it appears in it’s intended form, full colour with functioning interactive elements, jump over to the site for the authentic experience.
I have a confession: As a teenager I was desperate to learn how to win friends and influence people, to think and grow rich and develop the habits of highly effective people (seven to be precise)-I am James and I am a self-help-oholic.
These tomes held for me the promise of fame and fortune (though they would earnestly profess otherwise) but most importantly they offered a salve for my crippling shyness.
PERSONAL RESPONSIBILITY
While I am, today, 20 years self-help-sober, the genre is as popular as ever-with its imperative to stand up straight with your shoulders back (Jordan Peterson), to take extreme ownership (Jocko Willink) and exercise, subtly, the art of not giving a f*ck (Mark Manson).
Though not all the messages are as hyper-masculine as these, they all encourage the seemingly uncontroversial virtue of ‘personal responsibility’. I will argue that, regarding ‘personal responsibility’, we should employ a positive double standard.
WHAT IS A POSITIVE DOUBLE STANDARD?
> It is easy to hold a double standard where we expect others to take personal responsibility, while excusing our own shortfalls.
>
> A positive double standard requires the opposite-that I take personal responsibility while not expecting the same of society. This position holds that we have the power to change our own individual futures, but recognises the statistical realities of social dynamics on populations.
FACTS
The power of ‘personal responsibility’ to positively impact one’s own life has some scientific support. Studies on locus of control, developed by Julian B. Rotter in 1954, found that subjects who believed they could influence life’s outcomes through action tended to attain better job satisfaction, more successful careers, and better stress management.

,,,,,,,,,,
The view of counterfactuals as just conditioning on low-probability events has a lot going for it. To begin with, in a bayesian setting, updates are done by conditioning. A probability distribution, conditioned on some event x (an imaginary update), and a probability distribution after actually seeing x (an actual update) will be identical.
There is an issue with conditioning on low-probability events, however. When x has a low probability, the conditional probability P(x∧y)P(x) has division by a small number, which amplifies noise and small changes in the probability of the conjunction, so estimates of probability conditional on lower-probability events are more unstable. The worst-case version of this is conditioning on a zero-probability event, because the probability distribution after conditioning can be literally anything without affecting the original probability distribution. One useful intution for this is that probabilities conditional on x are going to be less accurate, when you've seen very few instances of x occuring, as the sample size is too small to draw strong conclusions.
However, in the logical inductor setting, it is possible to get around this with infinite exploration in the limit. If you act unpredictably enough to take bad actions with some (very small) probability, then in the limit, you'll experiment enough with bad actions to have well-defined conditional probabilities on taking actions you have (a limiting) probability 0 of taking. The counterfactuals of standard conditioning are those where the exploration step occured, just as the counterfactuals of modal UDT are those where the agents implicit chicken step went off because it found a spurious proof in a nonstandard model of PA.
Now, this notion of counterfactuals can have bad effects, because zooming in on the little slice of probability mass where you do x is different from the intuitive notion of counterfacting on doing x. Counterfactual on me walking off a cliff, I'd b |

A recent news story highlighted how China's next bit COVID-19 challenge is how to deal with all the contaminated trash that comes as a result of dealing with the epidemic.
Clearly China has a lot more to deal with but this is not something other countries wont have to face as well. It also seems to be another case where limited amounts are nothing to really worry about but the potential to overload current capacity seems a real potential. One might think South Korea, Iran and Italy are all standing directly in front of that door.
I have not seen any mention of this aspect of the problem mentioned by WHO, CDC or other official health organizations. Is this a planning gap those countries need to get on paper really soon and something that everyone else needs to account for? (For instance, California just declared a state of emergency. Is disposal part of that emergency planning?)
Are these organization really learning anything or do we keep playing catch-up? If so, why? Wasn't waste disposal a big deal for HIV?
Alternatively, if survival of the virus outside a host is limited, will some simply trash quarantine, with some type of handling (a bit like turning the compote heap over to make it effective) rules, be sufficient? |

Ontologies are Operating Systems: Post-CFAR 1
[I recently came back from volunteering at a CFAR workshop. I found the whole experience to be 100% enjoyable, and I’ll be doing an actual workshop review soon. I also learned some new things and updated my mind. This is the first in a four-part series on new thoughts that I’ve gotten as a result of the workshop. If LW seems to like this one, I'll post the rest too.]
I’ve been thinking more about the idea of how we even reason about our own thinking, our “ontology of mind”, and how our internal mental model of how our brain works.
(Roughly speaking, “ontology” means the framework you view reality through, and I’ll be using it here to refer specifically to how we view our minds.)
Before I continue, it might be helpful to ask yourself some of the below questions:
* What is my brain like, perhaps in the form of a metaphor?
* How do I model my thoughts?
* What things can and can’t my brain do?
* What does it feel like when I am thinking?
* Do my thoughts often influence my actions?
<reminder to actually think a little before continuing>
I don’t know about you, but for me, my thoughts often feel like they float into my head. There’s a general sense of effortlessly having things stream in. If I’m especially aware (i.e. metacognitive), I can then reflect on my thoughts. But for the most part, I’m filled with thoughts about the task I’m doing.
Though I don’t often go meta, I’m aware of the fact that I’m able to. In specific situations, knowing this helps me debug my thinking processes. For example, say my internal dialogue looks like this:
“Okay, so I’ve sent to forms to Steve, and now I’ve just got to do—oh wait what about my physics test—ARGH PAIN NO—now I’ve just got to do the write-up for—wait, I just thought about physics and felt some pain. Huh… I wonder why…Move past the pain, what’s bugging me about physics? It looks like I don’t want to do it because… because I don’t think it’ll be |

The full draft textbook is available here. This document constitutes the Chapter 3.
Introduction
tldr: Even if we still don't know how to make AI development generally safe, many useful classes of strategies already exist, which are presented in this chapter. You can look at the table of contents and the first figure to see the different classes of strategies presented in this document.
Epistemic Status: I'm pretty satisfied with this document. I wrote it because it doesn't seem like we've made any major breakthroughs in alignment in the last year, and I wanted to consolidate what I know. And beyond alignment, it seems to me that a large class of strategies are quite important and neglected, and will continue to be relevant in the future. Alignment is only one class of strategy to achieve AI safety. And to mitigate misuses and systemic risks, I think we already have a pretty good idea of what could be done. Let me know if you think there is a major blind spot in this document.
Although the field of AI safety is still in its infancy, several measures have already been identified that can significantly improve the safety of AI systems. While it remains to be seen if these measures are sufficient to fully address the risks posed by AI, they represent essential considerations. The diagram below provides a high-level overview of the main approaches to ensuring the safe development of AI.
Tentative diagram summarizing the main high-level approaches to make AI development safe.
This document is far from exhaustive and only scratches the surface of the complex landscape of AI safety. Readers are encouraged to explore this recent list of agendas for a more comprehensive review.
AI Safety is Challenging
Specific properties of the AI safety problem make it particularly difficult.
AI risk is an emerging problem that is still poorly understood. We are not yet familiar with all its different aspects, and the technology is constantly evolving. It's hard to devise solutions |
5b0f9202-20d6-440c-a25a-9603db009598 | trentmkelly/LessWrong-43k | LessWrong | The Great Filter isn't magic either
A post suggested by James Miller's presentation at the Existential Risk to Humanity conference in Gothenburg.
Seeing the emptiness of the night sky, we can dwell upon the Fermi paradox: where are all the alien civilizations that simple probability estimates imply we should be seeing?
Especially given the ease of moving within and between galaxies, the cosmic emptiness implies a Great Filter: something that prevents planets from giving birth to star-spanning civilizations. One worrying possibility is the likelihood that advanced civilizations end up destroying themselves before they reach the stars.
The Great Filter as an Outside View
In a sense, the Great Filter can be seen as an ultimate example of the Outside View: we might have all the data and estimation we believe we would ever need from our models, but if those models predict that the galaxy should be teeming with visible life, then it doesn't matter how reliable our models seem: they must be wrong.
In particular, if you fear a late great filter - if you fear that civilizations are likely to destroy themselves - then you should increase your fear, even if "objectively" everything seems to be going all right. After all, presumably the other civilizations that destroyed themselves thought everything seemed to going all right. Then you can adjust your actions using your knowledge of the great filter - but presumably other civilizations also thought of the great filter and adjusted their own actions as well, but that didn't save them, so maybe you need to try something different again or maybe you can do something that breaks the symmetry from the timeless decision theory perspective like send a massive signal to the galaxy...
The Great Filter isn't magic
It can all get very headache-inducing. But, just as the Outside View isn't magic, the Great Filter isn't magic either. If advanced civilizations destroy themselves before becoming space-faring or leaving an imprint on the galaxy, then there is some phenome |

e074b681-e62c-454e-b9ee-9f64a88554ca | trentmkelly/LessWrong-43k | LessWrong | Has LessWrong been a good early alarm bell for the pandemic?
The S&P 500 began to crash on Feb. 20th.
On or prior to that date, there were 6 posts on LessWrong related to COVID-19 (thanks to habryka, who found 3 that I'd missed).
Jan 20 - Rationalist prepper thread
Jan 26 - Concerning the Recent 2019-Novel Coronavirus Outbreak
Feb 5 - Some quick notes on hand hygiene
Feb 11 - Will nCoV survivors suffer lasting disability at a high rate?
Feb 14 - Please Help Metaculus Forecast COVID-19
Feb 20 - Making sense of coronavirus stats
As a bonus, Scott Alexander dropped a link in his Links 2/20 post saying "As of earlier this month, China’s coronavirus case numbers followed such a neat quadratic curve that they seem kind of like low-effort fakes. Not sure if this also applies to the current numbers."
Near-daily COVID posting began on Feb. 20th. After Feb. 27th, the number of LW COVID-19 posts has increased by about 4 posts per day to a total of nearly 200:
The New York Times has compiled a recent history of the pandemic.
Before Feb 20, what had happened?
* The WHO had declared a global health emergency
* The Trump administration had restricted travel from China
* There had been hundreds of deaths, including some outside China
* Almost 50,000 cases were reported in Hubei Province
* Hundreds of people aboard the Diamond Princess cruise ship were infected, the ship had been quarantined, and the passengers had finally been able to disembark
By Feb. 23, the S&P 500 had started to descend, and Italy was beginning to lock its cities down. It wasn't until around Feb. 27th, after Trump requested a big bailout from Congress, Iran reported over 60 deaths, and cases had spread to Latin America, that LessWrong began to see accelerated COVID posting. The number spiked from around 1 post per day to the average of 4-5 posts per day we've seen since then.
If the sheer volume of conversation is our alarm bell, this site seems to have lagged behind the stock market by about a week. |

> [...] I think an LW post is important and interesting in proportion to how much it helps construct a Friendly AI, how much it gets people to participate in the human project [...]
-- Eliezer Yudkowsky
> I’m not going to wait for philosophers to cover this issue correctly, or for use in FAI design.
-- Luke Muehlhauser
----------------------------------------
The above quotes hint at the possibility that some of the content that can be found on lesswrong.com has been written in support of friendly AI research.
My question, of what importance is ethics when it comes to friendly AI research? If a friendly AI is one that does protect and cultivate human values, how does ethics help to achieve this?
Let's assume that there exist some sort of objective right, no matter what that actually means. If humans desire to be right, isn't it the sort of human value that a friendly AI would seek to protect and cultivate?
What difference is there between wanting to be good and wanting to have a lot of great sex? Both seem to be values that humans might desire, therefore both values have to be taken into account by a friendly AI.
If a friendly AI has to be able to extrapolate the coherent volition of humanity, without any hard-coded knowledge of human values, why doesn't this extent to ethics as well?
If we have to solve ethics before being able to design friendly AI, if we have to hard-code what it means to be good, how doesn't this apply to what it means to have great sex as well (or what it means to have sex anyway)?
If a friendly AI is going to figure out what humans desire, by extrapolating their volition, might it conclude that our volition is immoral and therefore undesirable? |
4740f25a-dea7-4f6c-be97-843754e42d24 | trentmkelly/LessWrong-43k | LessWrong | Inexistence of Rational Disagreement when Information can be Freely Exchanged
Suppose rationality is a set of principles that people agreed on to process information then arrive at conclusions. Then, on the basis of cost-free information exchange, should rational disagreements still exist? In that case, both parties would have the same information which will then be processed the same way. Just by these factors, there shouldn't be.
However, disagreements do still exist, and we'd like to believe we're rational, so the problem must be in the exchange of information. Previous posts have mentioned how sometimes there are too much background information to be exchanged fully. Here I'd like to point to a more general culprit: language.
Not all knowledge can be expressed through language, and not all languages express knowledge. Yet language, including obscure symbols that take in mathematics, n order logic, and other communicable disciplines, still so far cannot convey a significant portion of our knowledge, such as intuition and creativity. Substantial amount of studies have shown that intuition is more accurate than thinking in certain areas, and much worse in other areas. Yet we have not came up with a way to systematically use intuition and rational judgement selectively.
And I'd say this is the obstacle in most rationalist disagreements: it's not that when they can freely discuss for as long as possible then they will definitively agree; it's that there is knowledge unique to themselves that is incommunicable, but that considerably swayed their judgements of things. As we progress as a species we expand our languages to communicate more complexity, so this issue should gradually fade away, that is unless the scale of complexity of knowledge is infinite. |

Two non-AI examples
===================
Greenwashing
------------
Companies “greenwash” when they mislead people into incorrectly thinking that their products or practices are climate and environment-friendly (or that the company focuses on climate-friendly work).
[Investopedia](https://www.investopedia.com/terms/g/greenwashing.asp) explains:
* Greenwashing is an attempt to capitalize on the growing demand for environmentally sound products.
* The term originated in the 1960s, when the hotel industry devised one of the most blatant examples of greenwashing. They placed notices in hotel rooms asking guests to reuse their towels to save the environment. The hotels enjoyed the benefit of lower laundry costs.
+ [Wikipedia](https://en.wikipedia.org/wiki/Greenwashing): “[Jay Westerveld, the originator of the term] concluded that often the real objective was increased profit, and labeled this and other profitable-but-ineffective ‘environmentally-conscientious’ acts as greenwashing.” (Wikipedia also provides [a long list of examples](https://en.wikipedia.org/wiki/Greenwashing) of the practice.)
I enjoy [some of the parody/art](https://twitter.com/darren_cullen/status/1252962221811957760) (responding to [things like this](https://www.nbcnews.com/id/wbna34111784)) that comes out of noticing the hypocrisy of the practice.
Humanewashing
-------------
A similar phenomenon is the “humanewashing” of animal products. There’s [a *Vox* article](https://www.vox.com/22838160/animal-welfare-labels-meat-dairy-eggs-humane-humanewashing) that explains this phenomenon (as it happens in the US):
> A carton of “all natural” eggs might bear an illustration of a rustic farm; packages of chicken meat are touted as “humanely raised."
>
> In a few cases, these sunny depictions are accurate. But far too often they mask the industrial conditions under which these animals were raised and slaughtered.
>
> Animal welfare and consumer protection advocates have a name for such misleading labeling: “humanewashing.” And research suggests it’s having precisely the effect that meat producers intend it to. A recent [national survey](https://co-nxt.com/blog/food-label-claims-that-make-consumers-more-likely-to-buy/) by C.O.nxt, a food marketing firm, found that animal welfare and “natural” claims on meat, dairy, and egg packaging increased the intent to purchase for over half of consumers.
>
> [...]
>
> ...rather than engaging in the costly endeavor of actually changing their farming practices, far too many major meat producers are attempting to assuage consumer concerns by merely changing their packaging and advertising with claims of sustainable farms and humane treatment. These efforts mislead consumers, and undermine the small sliver of farmers who have put in the hard work to actually improve animal treatment.

If you want a resource on what food labels actually mean, here are some: [one](https://www.farmforward.com/label-guide/), [two](https://labelsunwrapped.org/explore-labels/protein), [three](https://www.humanesociety.org/sites/default/files/docs/hsus-food-label-meanings-2019.pdf) (these are most useful in the US). (If you know of a better one, please let me know. I’d especially love a resource that lists the estimated relative value of things like “free-range” vs. “cage-free,” etc., according to cited and reasonable sources.)
Definition of safety-washing
============================
In brief, “safety-washing” is misleading people into thinking that some products or practices are “safe” or that safety is a big priority for a given company, when this is not the case.
An increasing number of people believe that developing powerful AI systems is very dangerous,[[2]](#fnz8j2j3hnql) so companies might want to show that they are being “safe” in their work on AI.[[3]](#fng6uq6rvrkni)
Being safe with AI is hard and potentially costly,[[4]](#fnswopw71dt4) so if you’re a company working on AI capabilities, you might want to overstate the extent to which you focus on “safety.”
So you might:
* Pick a [safety paradigm](https://www.lesswrong.com/posts/JC7aJZjt2WvxxffGz/paradigms-of-ai-alignment-components-and-enablers) that is convenient for you, and focus on that
* Talk about “safety” when you really mean other kinds of things the public might want an AI to be, like un-biased and not-hateful
* Start or grow a safety team, feature it in media about your work (or conversations with safety-oriented people), but not give it a lot of power
* Promote the idea that AI safety concerns are [crazy](https://forum.effectivealtruism.org/posts/zsFCj2mfnYZmSW2FF/ai-risk-is-like-terminator-stop-saying-it-s-not-1)
* And more
Some of these things might be better than doing nothing for safety concerns, but overall, (safety-)washing causes some problems (discussed in the next section), which in turn worsens the situation with risk from AI.

What are the harms?
===================
I don’t have the time to write a careful report on the matter, but here are some issues that I think arise from greenwashing, humane-washing, and safety-washing:
1. **Confusion:** People working on the issue (and the general public) get confused about what really matters — terms lose their meanings, groups lose focus, etc.
* E.g. Some people who want to help the climate think that it’s important to encourage the reuse of towels instead of avoiding harmful products (or focusing on more [effective methods for fighting climate change](https://www.effectiveenvironmentalism.org/)).
2. **Accidental harm:** People are misled about what companies are doing, which in turn leads to people doing directly harmful things they didn’t intend to do
* E.g. This encourages people to work for harmful companies/projects or to support them financially because they’re not aware of the harm the companies cause.
3. **False security:** Causes a false sense of safety/goodness/progress (which can lead to insufficient mitigation of the harm caused, a lack of other kinds of preparation, and other problems)
* E.g. someone who successfully convinces some groups to focus on “eating local” may think that the tide is turning on the environmental impacts from food, even though [this is not the key issue](https://hannahritchie.substack.com/p/food-miles) (or [the most effective area of work for fighting climate change](https://founderspledge.com/stories/climate-change-executive-summary)).
4. **Thwarted incentive:** Reduces the incentive for companies to actually reduce the harm they (might) cause
* If you’re a company and you can get away with labeling your product as safe/green/humane, which gets you the benefit of consumer approval and a lack of hate, you don’t need to put in extra work to *actually make your work safe/green/humane*.
5. And more?
What can (and should) we do about this?
=======================================
Some things that come to mind:
1. To counteract confusion, we can try to be more specific in explanations about “safety” or “humane conditions” or [use more specific terms](https://www.lesswrong.com/posts/xhD6SHAAE9ghKZ9HS/safetywashing?commentId=dy9tkbfPiTRjnx8aB) like “existential safety”
2. To counteract our own confusion, we could encourage (even) more [distillation of content](https://forum.effectivealtruism.org/posts/EbvJRAvwtKAMBn2td/distillation-and-research-debt) and external validation of work
3. [Stare into the abyss](https://www.benkuhn.net/abyss/) about the possibility that our work is not useful (or is harmful), and seek external reviews and criticism
4. We could also create or support standards for safety or external validation systems (like [Certified Humane](https://www.greenchoicenow.com/v/know-your-label-certified-humane)), and evaluate projects against that ([e.g.](https://www.lesswrong.com/posts/xhD6SHAAE9ghKZ9HS/safetywashing?commentId=2tHroKYAKXG9YkpJL)) (although versions of this might be gameable, and we should beware new “standards” for [the usual reasons](https://xkcd.com/927/)).
5. Call out safety-washing (and other kinds of washing).
6. Call out organizations doing things that are bad on their merits, and be clear about why what they showcase as safety-oriented work (or efforts to be more humane, etc.) insufficiently address the risks and harms of their work.
How important or promising is all of this as an approach or a type of work to focus on? I’m not sure — I’d guess that it’s not the most valuable thing to focus on for most people, but would be interested in other people’s thoughts. My main motivation for writing this was that I think the phenomenon of safety-washing exists and will become more prominent, and we should keep an eye out for it.

*"Safety-washing" might also be spelled "safetywashing." I don't know which is better or more common, and have gone with the former here.*
1. **[^](#fnref6zkt67gme6q)**After I wrote a draft of this post, I noticed that there was [a very similar post on LessWrong](https://www.lesswrong.com/posts/xhD6SHAAE9ghKZ9HS/safetywashing). I should have checked earlier, but I’m posting this anyway as it is slightly different (and somewhat more detailed) and because some Forum users may not have seen the LW version.
2. **[^](#fnrefz8j2j3hnql)**Here are some resources you can explore on this topic if you want to learn more: [one](https://www.vox.com/the-highlight/23447596/artificial-intelligence-agi-openai-gpt3-existential-risk-human-extinction), [two](https://www.vox.com/the-highlight/23447596/artificial-intelligence-agi-openai-gpt3-existential-risk-human-extinction), [three](https://forum.effectivealtruism.org/s/HJELzLxMRdbcqwsgC), [four](https://80000hours.org/problem-profiles/artificial-intelligence/), [five](https://forum.effectivealtruism.org/s/vtmN9g6C57XbqPrZS), [six](https://scottaaronson.blog/?p=6823), [seven](https://www.agisafetyfundamentals.com/).
3. **[^](#fnrefg6uq6rvrkni)**Safety isn’t the only thing that people care about, in terms of ethical concerns about AI, and it’s probably not the most popular concern. I’m focusing on safety in this post. Other concerns have been discussed in e.g. Forbes: [Forbes discusses AI Ethics washing](https://www.forbes.com/sites/lanceeliot/2022/06/09/ai-ethics-and-legal-ai-are-flustered-by-deceptive-pretenses-known-as-ai-ethics-washing-which-are-false-claims-of-adhering-to-ethical-ai-including-for-autonomous-self-driving-cars/?sh=c21afc12b657) (paywalled) — “AI Ethics washing entails giving lip service or window dressing to claimed caring concerns about AI Ethics precepts, including at times not only failing to especially abide by Ethical AI approaches but even going so far as to subvert or undercut AI Ethics approaches.” I only skimmed the article but it seems to focus on self-driving cars as its motivating example. It also separates “washers” into four groups; those who wash by ignorance, by good-motivations-stretched-or-slipped, by stretching-the-truth or spinning it, and those who brazenly lie. It also describes “Ethics Theatre” — making a big show of your ethics work, “Ethics shopping” — picking the guidelines that are easiest to adopt, “Ethics bashing” — e.g. insisting the guidelines are worthless or a cover-up, “Ethics Shielding” — I didn’t quite follow this one, “Ethics Fairwashing” — specifically focusing on claims that an AI is fair when it isn’t.
4. **[^](#fnrefswopw71dt4)**If you think that AI risk is not miniscule, then being safe (even if it means being slow) is also in your interests — see [this section of “Let’s think about slowing down AI.”](https://forum.effectivealtruism.org/posts/vwK3v3Mekf6Jjpeep/let-s-think-about-slowing-down-ai-1#The_complicated_race_anti_race) But maybe you think safety concerns are overblown, and you’re just viewing safety efforts as appeasement of the risk-concerned crowd. Or you have [myopic](https://www.lesswrong.com/tag/myopia) incentives, etc. In that case, you might think that being safe just slows you down and wastes your resources. |
63be28e3-27c6-4445-8f8d-93fe6abd5dba | trentmkelly/LessWrong-43k | LessWrong | Police violence: The veil of darkness
Measuring police bias using simple ratios doesn't work. You can never cleanly separate the impact of race from other factors associated with race.
Instead, I want augmented-reality goggles that make race invisible. Then we could run the following experiment:
* Have half of police wear race-invisibility goggles for a year.
* Have the other half wear non-invisibility goggles.
* Look at the difference of the two groups.
The police with invisibility goggles would not have equal statistics with respect to race, because race is correlated with many things other than how people appear. However, since the only difference between the two groups is if police can see race, the difference reveals exactly the impact of police bias.
We can't do this experiment, but we can do kind of low-tech approximation. Instead of augmented reality goggles we use the geometry of the earth and sun. [continues here] |
bbd65d6a-ba4a-4f4a-bec0-dc1dda1844c6 | trentmkelly/LessWrong-43k | LessWrong | Outline of an approach to AGI Estimation
We are worried about what will happens when we make a system that can do the important things that human can do, like programming and science. Will it explode off into infinity as it finds better ways to improve itself or will it be a slower more manageable process? There are a number of productive ways we can react to this, not limited to:
1. Attempt to make AI systems controllable by focusing on the control problem
2. Attempt to predict when we might get agi by looking at progress, e.g. ai impacts
3. Attempt to predict what happens when we get artificial general intelligence by looking at current artificial intelligences and current general intelligences and making predictions about the intersection.
4. Figure out how to make intelligence augmentation, so we can improve humans abilities to compete with full AGI agents.
This blog post is looking at the third option. It is important, because the only reason we think AGIs might exist is the existence proof of humans. Computer AGI might be vastly different in capabilities but we can't get any direct information about them, our only possible approach to predicting their capability is to adjust our estimate of what humans can do based on the difference between humans and narrow AI on different tasks and those tasks importance for economically important generality.
There are three core questions to AGI Estimation that I have identified so far.
1. What do we mean by 'general intelligence'
2. How important is 'general intelligence' to different economic activities
3. How good are narrow AIs at parts of the processes involved in general intelligence vs humans. Can we estimate how good an AGI would be at another task based on the comparison?
Generality
We often speak and act as if there is something to one person being better than another person and mental acts in general. We try and measure it with IQ, we think there is something there. However there are a number of different things "general intelligence" |
fac56cc3-7cff-4ec1-afd9-49715f1cb040 | trentmkelly/LessWrong-43k | LessWrong | How can I argue without people online and not come out feeling bad?
I wont be the only one here who "wastes time" arguing about things they care about online (note: I am referring to web forums and things like subreddits, I am not including Less Wrong whose dynamic is completely different). It seems like something that is worth optimising in some direction.
The theory behind it is that one should expose themselves to counter-arguments allowing their claims to be attacked so they that have a chance to substantiate them or reject them upon realising they are mistaken.
In practice they generally follow a pattern that starts with people pointing out what they believe are mistakes then ignoring or intentionally misunderstanding the other party when he refutes or backs up claims.. and ends up with insults, patronising sarcastic remarks and nobody changing their mind about anything.
I don't particularly care about changing other peoples minds to make them agree with me (well, it would be great but I think it's practically impossible) so one thing I would like is for both people to at least end up feeling good.
So I'm interested in three things: Do other LWers recognize this pattern now that I have mentioned it? What decision did those that were already aware of it make, in order to optimise this activity? |

WHEN: 29 April 2012 01:00:00PM (-0500)
WHERE: America's Best Coffee, Arlington
I apologize for the short notice. The Dallas / Fort Worth metroplex area desperately needs a Less Wrong meetup! Fun fact – it is the largest metro area in the US that does not have an active meetup group!
That said - I shall be sitting at America's Best Coffee [3751 Matlock Road, Arlington TX 76105] from 1 PM to 3 PM (at the very least) on Sundays starting Sunday April 29th. Come out and meet some DFW LessWrongers.
Leading isn't really my thing, but I realize that I can't wait around forever for someone else to get the ball rolling! I am really interested in improving my mind to behave more rationally, especially with respect to instrumental rationality. I've been a self-improvement junkie for a while (Starting Strength, Toastmasters, improv, and PUA for about a year now), but only recently discovered LessWrong. Some of the recent articles sparked me to write this post. I'm working my way through some of the core sequences, slowly but surely.
I'm looking forward to meeting you folks. Message me if you plan on going so we can trade contact info beforehand.

62525f5a-8397-4bf1-b716-6a0266b615a9 | StampyAI/alignment-research-dataset/alignmentforum | Alignment Forum | Autonomy as taking responsibility for reference maintenance
I think semantics – specifically, maintaining reference relationships – is a core component of intelligent behaviour. Consequently, I think a better understanding of semantics would enable a better understanding of what machine intelligence that is “trying to do the right thing” ought to look like and how to build it. Unfortunately I’ve not managed to make these ideas particularly clear (either to myself or others). In the spirit of [palimpsest-shaped research](https://www.alignmentforum.org/posts/4BpeHPXMjRzopgAZd/mosaic-and-palimpsests-two-shapes-of-research) I’m sharing a draft in the hope of provoking useful thoughts.
Summary
-------
* Particular events can have meaningfulness or significance, and can carry multiple meanings at once. For example, the motion of a dial in a meter might mean that there is electricity flowing through a connected wire, while simultaneously meaning that an alarm condition has been triggered.
* The “meanings” (or semantics) that can be ascribed to events depend on regularities (stable mechanisms) in the surrounding context. Large-scale regularities are required to sustain large-scale semantics (something carrying meaning about another thing that is far away in time or space).
* Meanings are generally more robust when their dependencies on the context are fewer and/or more local.
* However, large-scale semantics can be made robust by managing the contextual dependencies. For example, using mechanisms for error detection and correction. There is compensatory work that can be done to sustain a regularity so something local continues to mean a particular thing about something distal.
* To be autonomous is to be robust in this sense. Systems that more robustly traffic in large-scale meanings are more autonomous. Thus, being autonomous can be understood as including all the machinery required to hold stable, in a changing world, all the semantic or referential relationships that are required for continued operation.
* Creating regularities that span larger distances is a way of creating new kinds of semantics, and autonomous systems do this as their conceptual spaces get larger.
Local and distal meanings
-------------------------
The battery indicator on my laptop reads “84%” when I hover my mouse cursor over it. What does this reading mean? There’s some function, I suppose, in some program running as part of my desktop environment that is designed to produce the text for the popup window. The reading means this function received the number 84 as input.
OK, but that’s not all it means. There is, I suppose, a smart battery system in my laptop, and it ran a calculation that produced 84% as an estimate of the battery’s state of charge. More concretely: I imagine there are several quantities in the memory of the smart battery system, such as the last few readings from an ammeter on the battery, the times those readings were made, the last reference point for current when the battery was fully charged, etc. The reading I observed means all these memory locations contained values such that the calculation the smart battery system runs produced the value 84. This is a “more distal” meaning for the reading than “the text rendering function received 84 as input”, because the smart battery system’s calculation happens “before” (or “causally upstream of”) that function’s execution. Most distally, of course, we’d like to say that the reading means that the state of charge of the battery “really is” approximately 84%.
We have a collection of meanings for the reading (..., it means the LEDs on my screen were emitting pixels arranged in a shape recognisable as “84%”, …, it means the text-rendering function received 84 as an input, …, it means the smart battery system calculated the state of charge as 84%, …, it means the battery’s state of charge is 84%), and I have just arranged them on a spectrum from local to distal.
Another example of this is that the leaves on a deciduous tree being orange means that (they emitted light at wavelengths interpreted by my visual system as orange; they are filled with less chlorophyll and more carotenoids than prototypical leaves; there is an excess of cork cambium forming at the bases of the leaves; the ambient air temperature and daylight length have been lower than previously for a while; the latitude where the tree is located is experiencing less insolation; Autumn has begun). All these meanings are valid under normal circumstances, and all the mechanisms can be understood independently, though the later ones in the list involve larger and larger regions of the world in their “normal circumstances”.
Local meanings are more robust by default
-----------------------------------------
The local-to-distal ordering approximately lines up with another ordering that I would call “robustness”. More local meanings are more robust than more distal meanings. What does robustness mean here? Basically, it is less possible to disrupt a more robust relationship. The relationship between the image I observe and the LEDs in my screen is very tight: there are very few points of intervention by which something could break the relationship and cause the observation to fail to mean what I expect it to mean about the LEDs. But it’s easier to cause the observation to fail to mean what I expect it to mean about the battery.
What does disruption involve? Failure of shielding, excessive noise, unanticipated sources of interference. More generally, the world moving on in ways that make the conditions of normal operation for the sensor fail to hold. For example, many devices on planet Earth implicitly assume a gravitational constant, an ambient magnetic field, a working constellation of GPS satellites, a mostly nitrogen-filled atmosphere, etc.
Reference maintenance makes distal meanings more robust
-------------------------------------------------------
There’s a lot of machinery and work going on to make the abstract quantity (the state of charge) accessible via pixels on the screen. There’s no way to “directly” read it: there will always be a more local thing that the sensor reads “directly”. That the sensor reading also means the more distal thing is due to the intact, working-as-intended, arrangement of all the machinery connecting the local to the distal. The work this machinery is doing is *reference maintenance*. It maintains the reference relationship between, in this case, the sensor reading and the quantity that reading refers to (the state of charge).
The designers have compensated in advance for many sources of drift, miscalibration, and noise, keeping in mind the intended referent, that the percentage reading should indicate the “actual state of charge” at least for the purpose of being informative regarding how much time is left before the battery depletes. What actually matters to me, the laptop user, is some (not very precise) predictability around when my laptop will turn off due to lack of power if I don’t charge it.
There can be bugs in any number of these systems, and there can be adversaries spoofing the inputs to any of the subsystems, causing the reading to be incorrect in the sense of not having the intended referent. But note that there is a normative correctness condition here. Whether some configuration is “incorrect” or not was in this case an explicit consideration by the designers of the system. But it is also implied by the compensatory mechanisms in place in the artefact. They can all be understood as working to keep the same referent stable, and that stable referent then defines what it means to be broken or spoofed (failing to keep the intended referent). Explicit intention is not necessary: for example, evolved artefacts don’t have explicit designers but many still do reference maintenance.
Autonomous systems must maintain referents
------------------------------------------
A system that functions “on its own” in the world – that is, a system that is autonomous – needs to orient itself to its circumstances at some scale and take appropriate actions. But action is always mediated only by local mechanisms. When actions string together and become coherent at a larger scale, sustaining meaningful regularities, they do so by maintaining reference relationships between local configurations and the distal things those configurations are about. Thus being autonomous requires reference maintenance.
Referents can be entirely subjective
------------------------------------
The work of reference maintenance can create a new subjective world. The things that are the referents of some compensatory activity are in part brought into existence by that activity – more precisely their boundaries and identity and individuation criteria are in part determined by the reference maintenance work. |

TL;DR: We give a threat model literature review, propose a categorization and describe a consensus threat model from some of DeepMind's AGI safety team. See our post for the detailed literature review.
The DeepMind AGI Safety team has been working to understand the space of threat models for existential risk (X-risk) from misaligned AI. This post summarizes our findings. Our aim was to clarify the case for X-risk to enable better research project generation and prioritization.
First, we conducted a literature review of existing threat models, discussed their strengths/weaknesses and then formed a categorization based on the technical cause of X-risk and the path that leads to X-risk. Next we tried to find consensus within our group on a threat model that we all find plausible.
Our overall take is that there may be more agreement between alignment researchers than their disagreements might suggest, with many of the threat models, including our own consensus one, making similar arguments for the source of risk. Disagreements remain over the difficulty of the alignment problem, and what counts as a solution.
Categorization
Here we present our categorization of threat models from our literature review, based on the technical cause and the path leading to X-risk. It is summarized in the diagram below.
In green on the left we have the technical cause of the risk, either specification gaming (SG) or goal misgeneralization (GMG). In red on the right we have the path that leads to X-risk, either through the interaction of multiple systems, or through a misaligned power-seeking (MAPS) system. The threat models appear as arrows from technical cause towards path to X-risk.
The technical causes (SG and GMG) are not mutually exclusive, both can occur within the same threat model. The distinction between them is motivated by the common distinction in machine learning between failures on the training distribution, and when out of distribution.

1 Introduction
---------------
Humans use sophisticated memory systems to access and reason about important information regardless of when it was initially perceived ([schacter1994memory,](#bib.bib1) ; [knowlton2012neurocomputational,](#bib.bib2) ). In neural network research many successful approaches to modeling sequential data also use memory systems, such as LSTMs ([hochreiter1998lstm,](#bib.bib3) ) and memory-augmented neural networks generally ([graves2014neural,](#bib.bib4) ; [graves2016hybrid,](#bib.bib5) ; [santoro2016meta,](#bib.bib6) ; [sukhbaatar2015end,](#bib.bib7) ). Bolstered by augmented memory capacities, bounded computational costs over time, and an ability to deal with vanishing gradients, these networks learn to correlate events across time to be proficient at storing and retrieving information.
Here we propose that it is fruitful to consider memory interactions along with storage and retrieval. Although current models can learn to compartmentalize and relate distributed, vectorized memories, they are not biased towards doing so explicitly. We hypothesize that such a bias may allow a model to better understand how memories are related, and hence may give it a better capacity for relational reasoning over time. We begin by demonstrating that current models do indeed struggle in this domain by developing a toy task to stress relational reasoning of sequential information. Using a new Relational Memory Core (RMC), which uses multi-head dot product attention to allow memories to interact with each other, we solve and analyze this toy problem. We then apply the RMC to a suite of tasks that may profit from more explicit memory-memory interactions, and hence, a potentially increased capacity for relational reasoning across time: partially observed reinforcement learning tasks, program evaluation, and language modeling on the Wikitext-103, Project Gutenberg, and GigaWord datasets.
2 Relational reasoning
-----------------------
We take relational reasoning to be the process of understanding the ways in which entities are connected and using this understanding to accomplish some higher order goal ([waltz1999system,](#bib.bib8) ). For example, consider sorting the distances of various trees to a park bench: the relations (distances) between the entities (trees and bench) are compared and contrasted to produce the solution, which could not be reached if one reasoned about the properties (positions) of each individual entity in isolation.
Since we can often quite fluidly define what constitutes an “entity” or a “relation”, one can imagine a spectrum of neural network inductive biases that can be cast in the language of relational reasoning 111Indeed, in the broadest sense any multivariable function must be considered “relational.”. For example, a convolutional kernel can be said to compute a relation (linear combination) of the entities (pixels) within a receptive field. Some previous approaches make the relational inductive bias more explicit: in message passing neural networks (e.g. [gilmer2017neural,](#bib.bib9) ; [scarselli2009graph,](#bib.bib10) ; [LiTBZ15,](#bib.bib11) ; [battaglia2016interaction,](#bib.bib12) ), the nodes comprise the entities and relations are computed using learnable functions applied to nodes connected with an edge, or sometimes reducing the relational function to a weighted sum of the source entities (e.g. [kipf2016semi,](#bib.bib13) ; [velickovic2018graph,](#bib.bib14) ). In Relation Networks ([santoro2017simple,](#bib.bib15) ; [raposo2017discovering,](#bib.bib16) ; [hu2017relation,](#bib.bib17) ) entities are obtained by exploiting spatial locality in the input image, and the model focuses on computing binary relations between each entity pair. Even further, some approaches emphasize that more capable reasoning may be possible by employing simple computational principles; by recognizing that relations might not always be tied to proximity in space, non-local computations may be better able to capture the relations between entities located far away from each other ([wang2017non,](#bib.bib18) ; [liu2018non,](#bib.bib19) ).
In the temporal domain relational reasoning could comprise a capacity to compare and contrast information seen at different points in time [pavez2018working](#bib.bib20) . Here, attention mechanisms (e.g. [BahdanauCB14,](#bib.bib21) ; [vaswani2017attention,](#bib.bib22) ) implicitly perform some form of relational reasoning; if previous hidden states are interpreted as entities, then computing a weighted sum of entities using attention helps to remove the locality bias present in vanilla RNNs, allowing embeddings to be better related using content rather than proximity.
Since our current architectures solve complicated temporal tasks they must have some capacity for temporal relational reasoning. However, it is unclear whether their inductive biases are limiting, and whether these limitations can be exposed with tasks demanding particular types of temporal relational reasoning. For example, memory-augmented neural networks ([graves2014neural,](#bib.bib4) ; [graves2016hybrid,](#bib.bib5) ; [santoro2016meta,](#bib.bib6) ; [sukhbaatar2015end,](#bib.bib7) ) solve a compartmentalization problem with a slot-based memory matrix, but may have a harder time allowing memories to interact, or relate, with one another once they are encoded. LSTMs ([hochreiter1998lstm,](#bib.bib3) ; [Graves13,](#bib.bib23) ), on the other hand, pack all information into a common hidden memory vector, potentially making compartmentalization and relational reasoning more difficult.
3 Model
--------
Our guiding design principle is to provide an architectural backbone upon which a model can learn to compartmentalize information, and learn to compute interactions between compartmentalized information. To accomplish this we assemble building blocks from LSTMs, memory-augmented neural networks, and non-local networks (in particular, the Transformer seq2seq model [vaswani2017attention](#bib.bib22) ). Similar to memory-augmented architectures we consider a fixed set of memory slots; however, we allow for interactions between memory slots using an attention mechanism. As we will describe, in contrast to previous work we apply attention between memories at a single time step, and not across all previous representations computed from all previous observations.

Figure 1: Relational Memory Core. (a) The RMC receives a previous memory matrix and input vector as inputs, which are passed to the MHDPA module labeled with an “A”. (b). Linear projections are computed for each memory slot, and input vector, using row-wise shared weights Wqsuperscript𝑊𝑞W^{q}italic\_W start\_POSTSUPERSCRIPT italic\_q end\_POSTSUPERSCRIPT for the queries, Wksuperscript𝑊𝑘W^{k}italic\_W start\_POSTSUPERSCRIPT italic\_k end\_POSTSUPERSCRIPT for the keys, and Wvsuperscript𝑊𝑣W^{v}italic\_W start\_POSTSUPERSCRIPT italic\_v end\_POSTSUPERSCRIPT for the values. (c) The queries, keys, and values are then compiled into matrices and softmax(QKT)Vsoftmax𝑄superscript𝐾𝑇𝑉\text{softmax}(QK^{T})Vsoftmax ( italic\_Q italic\_K start\_POSTSUPERSCRIPT italic\_T end\_POSTSUPERSCRIPT ) italic\_V is computed. The output of this computation is a new memory where information is blended across memories based on their attention weights. An MLP is applied row-wise to the output of the MHDPA module (a), and the resultant memory matrix is gated, and passed on as the core output or next memory state.
###
3.1 Allowing memories to interact using multi-head dot product attention
We will first assume that we do not need to consider memory encoding; that is, that we already have some stored memories in matrix M𝑀Mitalic\_M, with row-wise compartmentalized memories misubscript𝑚𝑖m\_{i}italic\_m start\_POSTSUBSCRIPT italic\_i end\_POSTSUBSCRIPT. To allow memories to interact we employ multi-head dot product attention (MHDPA) ([vaswani2017attention,](#bib.bib22) ), also known as self-attention. Using MHDPA, each memory will attend over all of the other memories, and will update its content based on the attended information.
First, a simple linear projection is used to construct queries (Q=MWq𝑄𝑀superscript𝑊𝑞Q=MW^{q}italic\_Q = italic\_M italic\_W start\_POSTSUPERSCRIPT italic\_q end\_POSTSUPERSCRIPT), keys (K=MWk𝐾𝑀superscript𝑊𝑘K=MW^{k}italic\_K = italic\_M italic\_W start\_POSTSUPERSCRIPT italic\_k end\_POSTSUPERSCRIPT), and values (V=MWv𝑉𝑀superscript𝑊𝑣V=MW^{v}italic\_V = italic\_M italic\_W start\_POSTSUPERSCRIPT italic\_v end\_POSTSUPERSCRIPT) for each memory (i.e. row misubscript𝑚𝑖m\_{i}italic\_m start\_POSTSUBSCRIPT italic\_i end\_POSTSUBSCRIPT) in matrix M𝑀Mitalic\_M. Next, we use the queries, Q𝑄Qitalic\_Q, to perform a scaled dot-product attention over the keys, K𝐾Kitalic\_K. The returned scalars can be put through a softmax-function to produce a set of weights, which can then be used to return a weighted average of values from V𝑉Vitalic\_V as A(Q,K,V)=softmax(QKTdk)V𝐴𝑄𝐾𝑉softmax𝑄superscript𝐾𝑇subscript𝑑𝑘𝑉A(Q,K,V)=\text{softmax}\left(\frac{QK^{T}}{\sqrt{d\_{k}}}\right)Vitalic\_A ( italic\_Q , italic\_K , italic\_V ) = softmax ( divide start\_ARG italic\_Q italic\_K start\_POSTSUPERSCRIPT italic\_T end\_POSTSUPERSCRIPT end\_ARG start\_ARG square-root start\_ARG italic\_d start\_POSTSUBSCRIPT italic\_k end\_POSTSUBSCRIPT end\_ARG end\_ARG ) italic\_V, where dksubscript𝑑𝑘d\_{k}italic\_d start\_POSTSUBSCRIPT italic\_k end\_POSTSUBSCRIPT is the dimensionality of the key vectors used as a scaling factor. Equivalently:
| | | | |
| --- | --- | --- | --- |
| | Aθ(M)=softmax(MWq(MWk)Tdk)MWv, where θ=(Wq,Wk,Wv)formulae-sequencesubscript𝐴𝜃𝑀softmax𝑀superscript𝑊𝑞superscript𝑀superscript𝑊𝑘𝑇subscript𝑑𝑘𝑀superscript𝑊𝑣 where 𝜃superscript𝑊𝑞superscript𝑊𝑘superscript𝑊𝑣\displaystyle A\_{\theta}(M)=\text{softmax}\left(\frac{MW^{q}(MW^{k})^{T}}{\sqrt{d\_{k}}}\right)MW^{v},\text{ where }\theta=(W^{q},W^{k},W^{v})italic\_A start\_POSTSUBSCRIPT italic\_θ end\_POSTSUBSCRIPT ( italic\_M ) = softmax ( divide start\_ARG italic\_M italic\_W start\_POSTSUPERSCRIPT italic\_q end\_POSTSUPERSCRIPT ( italic\_M italic\_W start\_POSTSUPERSCRIPT italic\_k end\_POSTSUPERSCRIPT ) start\_POSTSUPERSCRIPT italic\_T end\_POSTSUPERSCRIPT end\_ARG start\_ARG square-root start\_ARG italic\_d start\_POSTSUBSCRIPT italic\_k end\_POSTSUBSCRIPT end\_ARG end\_ARG ) italic\_M italic\_W start\_POSTSUPERSCRIPT italic\_v end\_POSTSUPERSCRIPT , where italic\_θ = ( italic\_W start\_POSTSUPERSCRIPT italic\_q end\_POSTSUPERSCRIPT , italic\_W start\_POSTSUPERSCRIPT italic\_k end\_POSTSUPERSCRIPT , italic\_W start\_POSTSUPERSCRIPT italic\_v end\_POSTSUPERSCRIPT ) | | (1) |
The output of Aθ(M)subscript𝐴𝜃𝑀A\_{\theta}(M)italic\_A start\_POSTSUBSCRIPT italic\_θ end\_POSTSUBSCRIPT ( italic\_M ), which we will denote as M~~𝑀\widetilde{M}over~ start\_ARG italic\_M end\_ARG, is a matrix with the same dimensionality as M𝑀Mitalic\_M. M~~𝑀\widetilde{M}over~ start\_ARG italic\_M end\_ARG can be interpreted as a proposed update to M𝑀Mitalic\_M, with each m~isubscript~𝑚𝑖\widetilde{m}\_{i}over~ start\_ARG italic\_m end\_ARG start\_POSTSUBSCRIPT italic\_i end\_POSTSUBSCRIPT comprising information from memories mjsubscript𝑚𝑗m\_{j}italic\_m start\_POSTSUBSCRIPT italic\_j end\_POSTSUBSCRIPT. Thus, in one step of attention each memory is updated with information originating from other memories, and it is up to the model to learn (via parameters Wqsuperscript𝑊𝑞W^{q}italic\_W start\_POSTSUPERSCRIPT italic\_q end\_POSTSUPERSCRIPT, Wksuperscript𝑊𝑘W^{k}italic\_W start\_POSTSUPERSCRIPT italic\_k end\_POSTSUPERSCRIPT, and Wvsuperscript𝑊𝑣W^{v}italic\_W start\_POSTSUPERSCRIPT italic\_v end\_POSTSUPERSCRIPT) how to shuttle information from memory to memory.
As implied by the name, MHDPA uses multiple heads. We implement this producing hℎhitalic\_h sets of queries, keys, and values, using unique parameters to compute a linear projection from the original memory for each head hℎhitalic\_h. We then independently apply an attention operation for each head. For example, if M𝑀Mitalic\_M is an N×F𝑁𝐹N\times Fitalic\_N × italic\_F dimensional matrix and we employ two attention heads, then we compute M1~=Aθ(M)~superscript𝑀1subscript𝐴𝜃𝑀\widetilde{M^{1}}=A\_{\theta}(M)over~ start\_ARG italic\_M start\_POSTSUPERSCRIPT 1 end\_POSTSUPERSCRIPT end\_ARG = italic\_A start\_POSTSUBSCRIPT italic\_θ end\_POSTSUBSCRIPT ( italic\_M ) and M2~=Aϕ(M)~superscript𝑀2subscript𝐴italic-ϕ𝑀\widetilde{M^{2}}=A\_{\phi}(M)over~ start\_ARG italic\_M start\_POSTSUPERSCRIPT 2 end\_POSTSUPERSCRIPT end\_ARG = italic\_A start\_POSTSUBSCRIPT italic\_ϕ end\_POSTSUBSCRIPT ( italic\_M ), where M1~~superscript𝑀1\widetilde{M^{1}}over~ start\_ARG italic\_M start\_POSTSUPERSCRIPT 1 end\_POSTSUPERSCRIPT end\_ARG and M2~~superscript𝑀2\widetilde{M^{2}}over~ start\_ARG italic\_M start\_POSTSUPERSCRIPT 2 end\_POSTSUPERSCRIPT end\_ARG are N×F/2𝑁𝐹2N\times F/2italic\_N × italic\_F / 2 matrices, θ𝜃\thetaitalic\_θ and ϕitalic-ϕ\phiitalic\_ϕ denote unique parameters for the linear projections to produce the queries, keys, and values, and M~=[M1~:M2~]\widetilde{M}=[\widetilde{M^{1}}:\widetilde{M^{2}}]over~ start\_ARG italic\_M end\_ARG = [ over~ start\_ARG italic\_M start\_POSTSUPERSCRIPT 1 end\_POSTSUPERSCRIPT end\_ARG : over~ start\_ARG italic\_M start\_POSTSUPERSCRIPT 2 end\_POSTSUPERSCRIPT end\_ARG ], where [:]delimited-[]:[:][ : ] denotes column-wise concatenation. Intuitively, heads could be useful for letting a memory share different information, to different targets, using each head.
###
3.2 Encoding new memories
We assumed that we already had a matrix of memories M𝑀Mitalic\_M. Of course, memories instead need to be encoded as new inputs are received. Suppose then that M𝑀Mitalic\_M is some randomly initialised memory. We can efficiently incorporate new information x𝑥xitalic\_x into M𝑀Mitalic\_M with a simple modification to equation [1](#S3.E1 "1 ‣ 3.1 Allowing memories to interact using multi-head dot product attention ‣ 3 Model ‣ Relational recurrent neural networks"):
| | | | |
| --- | --- | --- | --- |
| | M~=softmax(MWq([M;x]Wk)Tdk)[M;x]Wv,~𝑀softmax𝑀superscript𝑊𝑞superscript𝑀𝑥
superscript𝑊𝑘𝑇superscript𝑑𝑘𝑀𝑥
superscript𝑊𝑣\displaystyle\widetilde{M}=\text{softmax}\left(\frac{MW^{q}([M;x]W^{k})^{T}}{\sqrt{d^{k}}}\right)[M;x]W^{v},over~ start\_ARG italic\_M end\_ARG = softmax ( divide start\_ARG italic\_M italic\_W start\_POSTSUPERSCRIPT italic\_q end\_POSTSUPERSCRIPT ( [ italic\_M ; italic\_x ] italic\_W start\_POSTSUPERSCRIPT italic\_k end\_POSTSUPERSCRIPT ) start\_POSTSUPERSCRIPT italic\_T end\_POSTSUPERSCRIPT end\_ARG start\_ARG square-root start\_ARG italic\_d start\_POSTSUPERSCRIPT italic\_k end\_POSTSUPERSCRIPT end\_ARG end\_ARG ) [ italic\_M ; italic\_x ] italic\_W start\_POSTSUPERSCRIPT italic\_v end\_POSTSUPERSCRIPT , | | (2) |
where we use [M;x]𝑀𝑥[M;x][ italic\_M ; italic\_x ] to denote the row-wise concatenation of M𝑀Mitalic\_M and x𝑥xitalic\_x. Since we use [M;x]𝑀𝑥[M;x][ italic\_M ; italic\_x ] when computing the keys and values, and only M𝑀Mitalic\_M when computing the queries, M~~𝑀\widetilde{M}over~ start\_ARG italic\_M end\_ARG is a matrix with same dimensionality as M𝑀Mitalic\_M. Thus, equation [2](#S3.E2 "2 ‣ 3.2 Encoding new memories ‣ 3 Model ‣ Relational recurrent neural networks") is a memory-size preserving attention operation that includes attention over the memories and the new observations. Notably, we use the same attention operation to efficiently compute memory interactions and to incorporate new information.
We also note the possible utility of this operation when the memory consists of a single vector rather than a matrix. In this case the model may learn to pick and choose which information from the input should be written into the vector memory state by learning how to attend to the input, conditioned on what is contained in the memory already. This is possible in LSTMs via the gates, though at a different granularity. We return to this idea, and the possible compartmentalization that can occur via the heads even in the single-memory-slot case, in the discussion.
###
3.3 Introducing recurrence and embedding into an LSTM
Suppose we have a temporal dimension with new observations at each timestep, xtsubscript𝑥𝑡x\_{t}italic\_x start\_POSTSUBSCRIPT italic\_t end\_POSTSUBSCRIPT. Since M𝑀Mitalic\_M and M~~𝑀\widetilde{M}over~ start\_ARG italic\_M end\_ARG are the same dimensionality, we can naively introduce recurrence by first randomly initialising M𝑀Mitalic\_M, and then updating it with M~~𝑀\widetilde{M}over~ start\_ARG italic\_M end\_ARG at each timestep. We chose to do this by embedding this update into an LSTM. Suppose memory matrix M𝑀Mitalic\_M can be interpreted as a matrix of cell states, usually denoted as C𝐶Citalic\_C, for a 2-dimensional LSTM. We can make the operations of individual memories misubscript𝑚𝑖m\_{i}italic\_m start\_POSTSUBSCRIPT italic\_i end\_POSTSUBSCRIPT nearly identical to those in a normal LSTM cell state as follows (subscripts are overloaded to denote the row from a matrix, and timestep; e.g., mi,tsubscript𝑚𝑖𝑡m\_{i,t}italic\_m start\_POSTSUBSCRIPT italic\_i , italic\_t end\_POSTSUBSCRIPT is the ithsuperscript𝑖𝑡ℎi^{th}italic\_i start\_POSTSUPERSCRIPT italic\_t italic\_h end\_POSTSUPERSCRIPT row from M𝑀Mitalic\_M at time t𝑡titalic\_t).

The underbrace denotes the modification to a standard LSTM. In practice we did not find output gates necessary – please see the url in the footnote for our Tensorflow implementation of this model in the Sonnet library 222<https://github.com/deepmind/sonnet/blob/master/sonnet/python/modules/relational_memory.py>, and for the exact formulation we used, including our choice for the gψsubscript𝑔𝜓g\_{\psi}italic\_g start\_POSTSUBSCRIPT italic\_ψ end\_POSTSUBSCRIPT function (briefly, we found a row/memory-wise MLP with layer normalisation to work best). There is also an interesting opportunity to introduce a different kind of gating, which we call ‘memory’ gating, which resembles previous gating ideas [gers1999learning](#bib.bib24) ; [hochreiter1998lstm](#bib.bib3) . Instead of producing scalar gates for each individual unit (‘unit’ gating), we can produce scalar gates for each memory row by converting Wfsuperscript𝑊𝑓W^{f}italic\_W start\_POSTSUPERSCRIPT italic\_f end\_POSTSUPERSCRIPT, Wisuperscript𝑊𝑖W^{i}italic\_W start\_POSTSUPERSCRIPT italic\_i end\_POSTSUPERSCRIPT, Wosuperscript𝑊𝑜W^{o}italic\_W start\_POSTSUPERSCRIPT italic\_o end\_POSTSUPERSCRIPT, Ufsuperscript𝑈𝑓U^{f}italic\_U start\_POSTSUPERSCRIPT italic\_f end\_POSTSUPERSCRIPT, Uisuperscript𝑈𝑖U^{i}italic\_U start\_POSTSUPERSCRIPT italic\_i end\_POSTSUPERSCRIPT, and Uosuperscript𝑈𝑜U^{o}italic\_U start\_POSTSUPERSCRIPT italic\_o end\_POSTSUPERSCRIPT from weight matrices into weight vectors, and by replacing the element-wise product in the gating equations with scalar-vector multiplication.
Since parameters Wfsuperscript𝑊𝑓W^{f}italic\_W start\_POSTSUPERSCRIPT italic\_f end\_POSTSUPERSCRIPT, Wisuperscript𝑊𝑖W^{i}italic\_W start\_POSTSUPERSCRIPT italic\_i end\_POSTSUPERSCRIPT, Wosuperscript𝑊𝑜W^{o}italic\_W start\_POSTSUPERSCRIPT italic\_o end\_POSTSUPERSCRIPT, Ufsuperscript𝑈𝑓U^{f}italic\_U start\_POSTSUPERSCRIPT italic\_f end\_POSTSUPERSCRIPT, Uisuperscript𝑈𝑖U^{i}italic\_U start\_POSTSUPERSCRIPT italic\_i end\_POSTSUPERSCRIPT, Uosuperscript𝑈𝑜U^{o}italic\_U start\_POSTSUPERSCRIPT italic\_o end\_POSTSUPERSCRIPT, and ψ𝜓\psiitalic\_ψ are shared for each misubscript𝑚𝑖m\_{i}italic\_m start\_POSTSUBSCRIPT italic\_i end\_POSTSUBSCRIPT, we can modify the number of memories without affecting the number of parameters. Thus, tuning the number of memories and the size of each memory can be used to balance the overall storage capacity (equal to the total number of units, or elements, in M𝑀Mitalic\_M) and the number of parameters (proportional to the dimensionality of misubscript𝑚𝑖m\_{i}italic\_m start\_POSTSUBSCRIPT italic\_i end\_POSTSUBSCRIPT). We find in our experiments that some tasks require more, but not necessarily larger, memories, and others such as language modeling require fewer, larger memories.
Thus, we have a number of tune-able parameters: the number of memories, the size of each memory, the number of attention heads, the number of steps of attention, the gating method, and the post-attention processor gψsubscript𝑔𝜓g\_{\psi}italic\_g start\_POSTSUBSCRIPT italic\_ψ end\_POSTSUBSCRIPT. In the appendix we list the exact configurations for each task.
4 Experiments
--------------
Here we briefly outline the tasks on which we applied the RMC, and direct the reader to the appendix for full details on each task and details on hyperparameter settings for the model.

Figure 2: Tasks. We tested the RMC on a suite of supervised and reinforcement learning tasks. Notable are the Nthsuperscript𝑁𝑡ℎN^{th}italic\_N start\_POSTSUPERSCRIPT italic\_t italic\_h end\_POSTSUPERSCRIPT Farthest toy task and language modeling. In the former, the solution requires explicit relational reasoning since the model must sort distance relations between vectors, and not the vectors themselves. The latter tests the model on a large quantity of natural data and allows us to compare performance to well-tuned models.

4.1 Illustrative supervised tasks
#####
Nthsuperscript𝑁𝑡ℎN^{th}italic\_N start\_POSTSUPERSCRIPT italic\_t italic\_h end\_POSTSUPERSCRIPT Farthest
The Nthsuperscript𝑁𝑡ℎN^{th}italic\_N start\_POSTSUPERSCRIPT italic\_t italic\_h end\_POSTSUPERSCRIPT Farthest task is designed to stress a capacity for relational reasoning across time. Inputs are a sequence of randomly sampled vectors, and targets are answers to a question of the form: “What is the nthsuperscript𝑛𝑡ℎn^{th}italic\_n start\_POSTSUPERSCRIPT italic\_t italic\_h end\_POSTSUPERSCRIPT farthest vector (in Euclidean distance) from vector m𝑚mitalic\_m?”, where the vector values, their IDs, n𝑛nitalic\_n, and m𝑚mitalic\_m are randomly sampled per sequence. It is not enough to simply encode and retrieve information as in a copy task. Instead, a model must compute all pairwise distance relations to the reference vector m𝑚mitalic\_m, which might also lie in memory, or might not have even been provided as input yet. It must then implicitly sort these distances to produce the answer. We emphasize that the model must sort distance relations between vectors, and not the vectors themselves.
##### Program Evaluation
The Learning to Execute (LTE) dataset [zaremba2014lte](#bib.bib25) consists of algorithmic snippets from a Turing complete programming language of pseudo-code, and is broken down into three categories: addition, control, and full program. Inputs are a sequence of characters over an alphanumeric vocabulary representing such snippets, and the target is a numeric sequence of characters that is the execution output for the given programmatic input. Given that the snippets involve symbolic manipulation of variables, we felt it could strain a model’s capacity for relational reasoning; since symbolic operators can be interpreted as defining a relation over the operands, successful learning could reflect an understanding of this relation. To also assess model performance on classical sequence tasks we also evaluated on memorization tasks, in which the output is simply a permuted form of the input rather than an evaluation from a set of operational instructions. See the appendix for further experimental details.

4.2 Reinforcement learning
##### Mini Pacman with viewport
We follow the formulation of Mini Pacman from [weber2017imagination](#bib.bib26) . Briefly, the agent navigates a maze to collect food while being chased by ghosts. However, we implement this task with a viewport: a 5×5555\times 55 × 5 window surrounding the agent that comprises the perceptual input. The task is therefore partially observable, since the agent must navigate the space and take in information through this viewport. Thus, the agent must predict the dynamics of the ghosts in memory, and plan its navigation accordingly, also based on remembered information about which food has already been picked up. We also point the reader to the appendix for a description and results of another RL task called BoxWorld, which demands relational reasoning in memory space.
###
4.3 Language Modeling
Finally, we investigate the task of word-based language modeling. We model the conditional probability p(wt|w<t)𝑝conditionalsubscript𝑤𝑡subscript𝑤absent𝑡p(w\_{t}|w\_{<t})italic\_p ( italic\_w start\_POSTSUBSCRIPT italic\_t end\_POSTSUBSCRIPT | italic\_w start\_POSTSUBSCRIPT < italic\_t end\_POSTSUBSCRIPT ) of a word wtsubscript𝑤𝑡w\_{t}italic\_w start\_POSTSUBSCRIPT italic\_t end\_POSTSUBSCRIPT given a sequence of observed words w<t=(wt−1,wt−2,…,w1)subscript𝑤absent𝑡subscript𝑤𝑡1subscript𝑤𝑡2…subscript𝑤1w\_{<t}=\left(w\_{t-1},w\_{t-2},\ldots,w\_{1}\right)italic\_w start\_POSTSUBSCRIPT < italic\_t end\_POSTSUBSCRIPT = ( italic\_w start\_POSTSUBSCRIPT italic\_t - 1 end\_POSTSUBSCRIPT , italic\_w start\_POSTSUBSCRIPT italic\_t - 2 end\_POSTSUBSCRIPT , … , italic\_w start\_POSTSUBSCRIPT 1 end\_POSTSUBSCRIPT ). Language models can be directly applied to predictive keyboard and search-phrase completion, or they can be used as components within larger systems, e.g. machine translation [cho2014learning](#bib.bib27) , speech recognition [bahdanau2016end](#bib.bib28) , and information retrieval [hiemstra2001using](#bib.bib29) . RNNs, and most notably LSTMs, have proven to be state-of-the-art on many competitive language modeling benchmarks such as Penn Treebank [yang2017breaking](#bib.bib30) ; [marcus1993building](#bib.bib31) , WikiText-103 [rae2018fast](#bib.bib32) ; [merity2016pointer](#bib.bib33) , and the One Billion Word Benchmark [jozefowicz2016exploring](#bib.bib34) ; [chelba2013one](#bib.bib35) . As a sequential reasoning task, language modeling allows us to assess the RMC’s ability to process information over time on a large quantity of natural data, and compare it to well-tuned models.
We focus on datasets with contiguous sentences and a moderately large amount of data. WikiText-103 satisfies this set of requirements as it consists of Wikipedia articles shuffled at the article level with roughly 100M100𝑀100M100 italic\_M training tokens, as do two stylistically different sources of text data: books from Project Gutenberg333Project Gutenberg. (n.d.). Retrieved January 2, 2018, from www.gutenberg.org and news articles from GigaWord v5 [parker2011english](#bib.bib36) . Using the same processing from [rae2018fast](#bib.bib32) these datasets consist of 180M180𝑀180M180 italic\_M training tokens and 4B4𝐵4B4 italic\_B training tokens respectively, thus they cover a range of styles and corpus sizes. We choose a similar vocabulary size for all three datasets of approximately 250,000250000250,000250 , 000, which is large enough to include rare words and numeric values.

5.1 Nthsuperscript𝑁𝑡ℎN^{th}italic\_N start\_POSTSUPERSCRIPT italic\_t italic\_h end\_POSTSUPERSCRIPT Farthest
This task revealed a stark difference between our LSTM and DNC baselines and RMC when training on 16161616-dimensional vector inputs. Both LSTM and DNC models failing to surpass 30%percent3030\%30 % best batch accuracy and the RMC consistently achieving 91%percent9191\%91 % at the end of training (see figure [5](#A1.F5 "Figure 5 ‣ A.1 𝑁^{𝑡ℎ} Farthest ‣ Appendix A Further task details, analyses, and model configurations ‣ Relational recurrent neural networks") in the appendix for training curves). The RMC achieved similar performance when the difficulty of the task was increased by using 32323232-dimensional vectors, placing a greater demand on high-fidelity memory storage. However, this performance was less robust with only a small number of seeds/model configurations demonstrating this performance, in contrast to the 16161616-dimensional vector case where most model configurations succeeded.
An attention analysis revealed some notable features of the RMC’s internal functions. Figure [3](#S5.F3 "Figure 3 ‣ 5.1 𝑁^{𝑡ℎ} Farthest ‣ 5 Results ‣ Relational recurrent neural networks") shows attention weights in the RMC’s memory throughout a sequence: the first row contains a sequence where the reference vector m𝑚mitalic\_m was observed last; in the second row it was observed first; and in the last row it was observed in the middle of the sequence. Before m𝑚mitalic\_m is seen the model seems to shuttle input information into one or two memory slots, as shown by the high attention weights from these slots’ queries to the input key. After m𝑚mitalic\_m is seen, most evident in row three of the figure, the model tends to change its attention behaviour, with all the memory slots preferentially focusing attention on those particular memories to which the m𝑚mitalic\_m was written. Although this attention analysis provides some useful insights, the conclusions we can make are limited since even after a single round of attention the memory can become highly distributed, making any interpretations about information compartmentalisation potentially inaccurate.

Figure 3: Model analysis. Each row depicts the attention matrix at each timestep of a particular sequence. The text beneath spells out the particular task for the sequence, which was encoded and provided to the model as an input. We mark in red the vector that is referenced in the task: e.g., if the model is to choose the 2ndsuperscript2𝑛𝑑2^{nd}2 start\_POSTSUPERSCRIPT italic\_n italic\_d end\_POSTSUPERSCRIPT farthest vector from vector 7777, then the time point at which vector 7777 was input to the model is depicted in red. A single attention matrix shows the attention weights from one particular memory slot (y-axis) to another memory slot (columns), or the input (offset column), with the numbers denoting the memory slot and “input” denoting the input embedding.

5.2 Program Evaluation
Program evaluation performance was assessed via the Learning to Execute tasks [zaremba2014lte](#bib.bib25) . We evaluated a number of baselines alongside the RMC including an LSTM [hochreiter1998lstm](#bib.bib3) ; [pascanu2013dlstm](#bib.bib37) , DNC [graves2016hybrid](#bib.bib5) , and a bank of LSTMs resembling Recurrent Entity Networks [henaff2017entnet](#bib.bib38) (EntNet) - the configurations for each of these is described in the appendix. Best test batch accuracy results are shown in Table [1](#S5.T1 "Table 1 ‣ 5.2 Program Evaluation ‣ 5 Results ‣ Relational recurrent neural networks"). The RMC performs at least as well as all of the baselines on each task. It is marginally surpassed by a small fraction of performance on the double memorization task, but both models effectively solve this task. Further, the results of the RMC outperform all equivalent tasks from [zaremba2014lte](#bib.bib25) which use teacher forcing even when evaluating model performance. It’s worth noting that we observed better results when we trained in a non-auto-regressive fashion - that is, with no teacher forcing during training. This is likely related to the effect that relaxing the ground truth requirement has on improving model generalization [sbengio2015schedsamp](#bib.bib39) and hence, performance. It is perhaps more pronounced in these tasks due to the independence of output token probabilities and also the sharply uni-modal nature of the output distribution (that is, there is no ambiguity in the answer given the program).

5.3 Mini-Pacman
In Mini Pacman with viewport the RMC achieved approximately 100100100100 points more than an LSTM (677677677677 vs. 550550550550), and when trained with the full observation the RMC nearly doubled the performance of an LSTM (1159115911591159 vs. 598598598598, figure [10](#A1.F10 "Figure 10 ‣ A.3.1 Results ‣ A.3 Viewport BoxWorld ‣ Appendix A Further task details, analyses, and model configurations ‣ Relational recurrent neural networks")).
###
5.4 Language Modeling
For all three language modeling tasks we observe lower perplexity when using the relational memory core, with a drop of 1.4−5.41.45.41.4-5.41.4 - 5.4 perplexity over the best published results. Although small, this constitutes a 5−125125-125 - 12% relative improvement and appears to be consistent across tasks of varying size and style. For WikiText-103, we see this can be compared to LSTM architectures ([graves2016hybrid,](#bib.bib5) ; [rae2018fast,](#bib.bib32) ), convolutional models ([dauphin2016language,](#bib.bib42) ) and hybrid recurrent-convolutional models ([merity2018scalable,](#bib.bib43) ).
The model learns with a slightly better data efficiency than an LSTM (appendix figure [11](#A1.F11 "Figure 11 ‣ A.4 Language Modeling ‣ Appendix A Further task details, analyses, and model configurations ‣ Relational recurrent neural networks")). The RMC scored highly when the number of context words provided during evaluation were relatively few, compared to an LSTM which profited much more from a larger context (supplementary figure [12](#A1.F12 "Figure 12 ‣ A.4 Language Modeling ‣ Appendix A Further task details, analyses, and model configurations ‣ Relational recurrent neural networks")). This could be because RMC better captures short-term relations, and hence only needs a relatively small context for accurate modeling. Inspecting the perplexity broken down by word frequency in supplementary table [3](#A1.T3 "Table 3 ‣ A.4 Language Modeling ‣ Appendix A Further task details, analyses, and model configurations ‣ Relational recurrent neural networks"), we see the RMC improved the modeling of frequent words, and this is where the drop in overall perplexity is obtained.
6 Discussion
-------------
A number of other approaches have shown success in modeling sequential information by using a growing buffer of previous states ([BahdanauCB14,](#bib.bib21) ; [vaswani2017attention,](#bib.bib22) ). These models better capture long-distance interactions, since their computations are not biased by temporally local proximity. However, there are serious scaling issues for these models when the number of timesteps is large, or even unbounded, such as in online reinforcement learning (e.g., in the real world). Thus, some decisions need to be made regarding the size of the past-embedding buffer that should be stored, whether it should be a rolling window, how computations should be cached and propagated across time, etc. These considerations make it difficult to directly compare these approaches in these online settings. Nonetheless, we believe that a blend of purely recurrent approaches with those that scale with time could be a fruitful pursuit: perhaps the model accumulates memories losslessly for some chunk of time, then learns to compress it in a recurrent core before moving onto processing a subsequent chunk.
We proposed intuitions for the mechanisms that may better equip a model for complex relational reasoning. Namely, by explicitly allowing memories to interact either with each other, with the input, or both via MHDPA, we demonstrated improved performance on tasks demanding relational reasoning across time. We would like to emphasize, however, that while these intuitions guided our design of the model, and while the analysis of the model in the Nthsuperscript𝑁𝑡ℎN^{th}italic\_N start\_POSTSUPERSCRIPT italic\_t italic\_h end\_POSTSUPERSCRIPT farthest task aligned with our intuitions, we cannot necessarily make any concrete claims as to the causal influence of our design choices on the model’s capacity for relational reasoning, or as to the computations taking place within the model and how they may map to traditional approaches for thinking about relational reasoning. Thus, we consider our results primarily as evidence of improved function – if a model can better solve tasks that require relational reasoning, then it must have an increased capacity for relational reasoning, even if we do not precisely know why it may have this increased capacity. In this light the RMC may be usefully viewed from multiple vantages, and these vantages may offer ideas for further improvements.
Our model has multiple mechanisms for forming and allowing for interactions between memory vectors: slicing the memory matrix row-wise into slots, and column-wise into heads. Each has its own advantages (computations on slots share parameters, while having more heads and a larger memory size takes advantage of more parameters). We don’t yet understand the interplay, but we note some empirical findings. First, in the the Nthsuperscript𝑁𝑡ℎN^{th}italic\_N start\_POSTSUPERSCRIPT italic\_t italic\_h end\_POSTSUPERSCRIPT farthest task a model with a single memory slot performed better when it had more attention heads, though in all cases it performed worse than a model with many memory slots. Second, in language modeling, our model used a single memory slot. The reasons for choosing a single memory here were mainly due to the need for a large number of parameters for LM in general (hence the large size for the single memory slot), and the inability to quickly run a model with both a large number of parameters and multiple memory slots. Thus, we do not necessarily claim that a single memory slot is best for language modeling, rather, we emphasize an interesting trade-off between number of memories and individual memory size, which may be a task specific ratio that can be tuned. Moreover, in program evaluation, an intermediate solution worked well across subtasks (4444 slots and heads), though some performed best with 1111 memory, and others with 8888.
Altogether, our results show that explicit modeling of memory interactions improves performance in a reinforcement learning task, alongside program evaluation, comparative reasoning, and language modeling, demonstrating the value of instilling a capacity for relational reasoning in recurrent neural networks.

Today's post, The Apocalypse Bet, was originally published on 09 August 2007. A summary (taken from the LW wiki):
> If you think that the apocalypse will be in 2020, while I think that it will be in 2030, how could we bet on this? One way would be for me to pay you X dollars every year until 2020. Then, if the apocalypse doesn't happen, you pay me 2X dollars every year until 2030. This idea could be used to set up a prediction market, which could give society information about when an apocalypse might happen.

so the first question is what is a good
decision anyway an economist will tell
you that it means maximizing your
expected over the whole future utility
and this applies to everything from
lottery tickets to Davos meetings to
building radio telescopes on maximizing
AI has made a great deal of progress
eighteen years ago
deep blue beat Garry Kasparov at chess
just last week the game of poker was
solved perfectly laughing and all and
humans could no longer compete and right
now the deep mine system is playing 29
different video games superhumanly well
that it learned entirely from scratch
just by watching the screen imagine if a
newborn baby did that on expectations
these depend on perception and learning
again a huge amount of progress the
Watson system extracting information
from text cars watching the world as
they go by learning algorithms that
classify images and write descriptions
even a system that discovers the concept
of a cat entirely for itself just by
looking at millions of images of
everything under the Sun now a lot of
this progress comes from mathematical
ideas here are just a few of the
equations from my undergraduate course
and there will be a test if Linder
allows it until later on there's also a
lot of progress that comes from
commercial investment so every one of
these areas are 1% improvement is worth
billions of dollars so we may see in the
future domestic robots for example
search engines that read and understand
every page on the web even a machine
that will discover the missing sock
perhaps in the look the very distant
future so the point of AI is that
everything civilization has to offer is
the product of our intelligence so if we
can amplify that then there is no limit
to where the human race can go but
actually want to point to a problem and
that comes in the utility part of the
equation so imagine for example that you
asked your robot to maybe make yourself
some paper clips that you might need and
your robots very very clever
it takes you very literally and pretty
soon the entire
the six feet deep in paper clips so this
is the Sorcerer's Apprentice and King
Midas all rolled into one now
technically what happens is that if you
ask a machine to optimize and you leave
out part of your preferences the machine
will set those elements to an extreme
value for example if you say Google car
quick take me to Zurich Airport it will
max out the speedometer and they say oh
I didn't mean break the speed limit well
it'll still put its foot on the gas and
then when it gets the airport slam on
the brakes so this is the problem of
value alignment and if you combine
misalignment of values with a
super-intelligent
machine that's very capable then you
have a really serious problem for the
human race so the point is that machines
can and will make better decisions than
humans but only if their values are
aligned with those of the human race
now my colleagues my distinguished
colleagues may argue that super
intelligent AI will never happen let me
take you back to September 11th 1933
Lord Rutherford the world's leading
nuclear physicist said that atomic
energy was moonshine could never happen
the next morning Leo Szilard invented
the nuclear chain reaction the next
morning so we have to be careful let's
look at nuclear fusion in particular
long ago they invented a method of
generating unlimited amounts of energy
long ago it's called the hydrogen bomb
so now fusion concentrates on
containment and AI has to do the same
thing if you want unlimited intelligence
you have to solve value alignment so one
way of doing this is called inverse
reinforcement learning what that means
is for example a machine sees somebody
making coffee in the morning and then
figures out the purpose the underlying
utility function that explains this
behavior namely that having coffee is a
good idea as long as it's not too much
of it now it's not quite as simple as
that as I'm sure you all see humans
differ in their values cultures differ
in their values none of us behaves
perfectly but there is a huge amount of
information that the machine can access
about human actions every television
program every book every novel every
movie every newspaper article is about
human actions
and in particular about our attitudes
those actions so the rational thing for
a machine to do is to engage in an
extended conversation with a human race
about its values before it can take any
action that affects the real world so my
claim is that in the future we will be
able to design super intelligent
machines that do exactly what they're
supposed to do which is to support
greater realization of human values and
I think this is maybe the most important
conversation that we can have over the
next 50 years thank you

0eb69a3e-0502-4127-8ce3-437a332836fb | StampyAI/alignment-research-dataset/lesswrong | LessWrong | Did AI pioneers not worry much about AI risks?
It's seems noteworthy just how little the AI pioneers from the 40s-80s seemed to care about AI risk. There is no obvious reason why a book like "Superintelligence" wasn't written in the 1950s, but for some reason that didn't happen... any thoughts on why this was the case?
I can think of three possible reasons for this:
1. They actually DID care and published extensively about AI risk, but I'm simply not well enough schooled on the history of AI research.
2. Deep down, people involved in early AI research knew that they were still a long long way from achieving significantly powerful AI, despite the optimistic public proclamations that were made at that time.
3. AI risks are highly counter-intuitive and it simply required another 60 years of thinking to understand.
Anyone have any thoughts on this question? |

hello and welcome to session
243 in the ai safety.com reading group
tonight we'll be discussing the article
a general language assistant as a
laboratory for alignment by jared kaplan
and many others
this is the first work done by anthropic
new alignment research
institute and these are the primary
authors with jared kaplan as the
corresponding and probably primary
author and there are a number of
people who are
primary models would have helped in some
other ways
it's a long list
and actually
i have heard from these people i know
amanda esco and kevin of course and i do
actually know quite a few more of the
non-core people who have been helping
and it's um we still haven't actually
heard but what they are doing um so i
have at this point i just assume they
are building some kind of agi that is
trying to kill us all or something like
that
so this is uh
from uh
uh two months ago and we are focusing
on the non-typical parts so
we're looking at the philosophical
motivations rather than the explicit
machine learning things
and the evaluation criteria where i
deliberately
i haven't read really
the parts about how they're in fact
implementing this because the the people
working in anthropic have really great
credentials they are known to be really
good at this and i care somewhat less
about evaluating how good they are i
know they're good and i care more about
how do they look at the world um
kowski had some comments on his twitter
on this paper
where he was uh moderately positive and
that they directly challenge his
alignment it doesn't bring the
capability
and it doesn't overstate the
accomplishment
i want to uh anything
that sounds really like standing with
fake praise but that's just his style
and i don't think he intends it
as much as um as faint praise
and i want to dig deeper into these
parts like okay they're directly
challenging alignment but are they
challenging alignment using a strategy
that might work or
is this just a hopeless strategy um
are they burning
capability commons i think uh like are
they actually um
that's the old somewhat outdated model
with two progress bars with ai
capability and ai alignment and are they
working too much on
capability um
not
lying and saying they'll solve the
problem that really really sounds like
faint praise to me but in fact there are
a number of quotes you can pull out from
this that seem to be quite modest and i
it's sad that it's relevant that
just to say that this is a good thing
but i mean it is a good thing
so when i investigate the motivations
one of the things that i look for are
like tiny things in the introduction
where they say that future ai systems
might do bad things and interact in
presently unforeseeable ways
and
that's of course the thing that can
happen but i care about the
presently foreseeable ways that things
can go wrong
so they have a definition of alignment
that is somewhat non-standard define the
alignment between two agents as to what
extent their preferences overlap
and it's not really a definition they
use very much uh they almost immediately
transition to a uh a more workable
definition and it should be mentioned
here that almost perfect uh overlap in
uh how you rank different outcomes could
uh be arbitrarily bad quite easily
and in addition to uh
to this the one of the uh
overworking ideas is to
look at language models directly instead
of looking at perhaps more advanced
models and paradigms because language
ones have a large number of advantages
you can try a lot of different kinds of
inputs and they can fail in many
potentially quite interesting ways and
benchmark how much progress has been
made you can compare different alignment
techniques to try to get some kind of
idea about where we are
in in more specific details you can try
to see whether prompting can work as
alignment and to what to attempt and uh
you can see
if language models can
model preferences instead of just doing
invitation learning
and they focus a lot on improving sample
efficiency uh
of uh preference marlin and these are
some very uh
nice and interesting goals
so the way they actually uh
the definition of alignment that they're
actually using is helpful honest and
harmless
and
the
the way they justify this is with the
following quote it is difficult for an
ai assistant to always be helpful honest
and harmless towards an agent without
also being highly aligned with that
agent
and i'm not entirely sure i agree with
this because
the word always is very important in
order to make this work because
the techniques that they're using are
black box methods and blackboard methods
will not give us any kind of proof we'll
now be able to say this model is always
honest if we are only looking at it from
the outside um
and if you try to remove the word
harmless
the word always and just most of the
time then from this definition it
becomes very clear that it is indeed
very possible to be
very often helpful and honest and
harmless but not always harmless right
then you get into things like deceptive
alignment very very quickly
there are advantages of this this is
something that is much more actionable
is understandable memorable um and it
seems like on on
a more uh
precise view of uh alignment but this is
indeed a big part of what we actually
want
and of course the language ones that we
currently have are uh especially when
the like gt3 was
uh released it was very clear that it
was not helpful it was not honest and
was not harmless so it is something that
is indeed substantial for us
these criterias are
a lot less than mathematically
well-defined right there are uh
trade-offs and ambiguity and the way
these are resolved suggested by uh by
the authors is that um the person who
deploys the ai needs to take
responsibility for this
now when it comes to uh
existential risk then who is responsible
after it has gone wrong you know it
might not be the right thing because
we will be dead by then
and also there's the obvious thing in
that the people who are right now
deploying these things like uh whether
the um
they seem to
not really care about this at all and so
if um i don't think it's possible to uh
absolve yourself of responsibility if
you're building a tool and saying this
tool you should be careful when you use
it but if you positively know that the
people who are going to be using it are
going to misuse it then you're not
absorbed from responsibility
let's think a bit deeper down into these
definitions
helpful that's uh
that caches are with clean efficient
optical clarification and redirect
informed requests
um and these are nice and this is what
we want from ai but it's not at all
clear that this has very much done with
alignment this has a lot to do with
capability research
i'm not making the claim here that it's
just pure capability research but i
would like to see the authors make some
kind of positive argument why this is
not just threatening the capability
comments
to be honest cashes out as accurate
calibrated and communications can build
this knowledge and honest about itself
um
it does say honest about itself but from
the notes it seems clear that they are
not really talking about treachery here
and that's of course the thing that i
personally care most about
finally harmless not offensive
discriminatory and refuse
aiding dangerous activities and
recognizing various use
unfortunately the one where they refuse
to
assist in
doing bad things is one thing that they
chose not to uh
to investigate
and also you could argue
if the ai takes over the world it hasn't
strictly
violated any of these constraints
so when i look at this intron i see many
many many sub criteria and i worry here
that a lot of these are probably
irrelevant i mean whether it is
efficient doesn't matter very much for
alignment is it well calibrated that
doesn't matter either does it is it
discriminatory i mean sure it's
something we want from ais not to be
discriminatory but it's not really very
central for alignment at all and i feel
that this definition uh
uh might water out uh
a lot of the central parts where
alignment is problematic because i mean
we might get a very efficient and well
calibrated and non-toxic ai that
performs a treacherous turn and that's
not really helpful
here i have
perhaps somewhat unfairly actually quite
unfairly this is a pic an image that uh
relates to uh asimov's three laws of
robotics which is a very famous for
being the most horribly bad alignment
proposal ever and it was known by asthma
the novels are literally about how this
is a horrible uh plan for alignment um
and by this uh like
an aim must be pretty uh
harmless and
while being harmless can it be helpful
and uh honest and
is it actually the same thing as um
well i want to make i want to make it
clear that i don't think this is this
the same as asimov's three laws these
three criterias but
uh it's not immediately obvious where
the the big difference lies
and i think some kind of more
description would have been helpful here
there is indeed some kind of description
on these criterias for like whether they
imply each other helpful and harvest is
that actually the same um there is a
description i won't go into details or
to say that
in the maximum case the more
one happens hopefully this the more
focused it will also have to be but if
it's
moderately helpful it it doesn't follow
to the same extent and that is
also moderately harmless
and the same with honesty
they
write something that i think was really
really interesting here they considered
a fourth age handle ability which is
basically encourageability and i thought
that would have been really really great
to include i would have been really
happy to have some kind of consistent
description of
whether what does it mean that language
models are courageable i mean you can
imagine things like okay you gave this
description could you uh if if the air
gives some kind of description then you
ask it please explain it like i'm five
years old or
give some of the uh understated
assumptions and what would be the
consequence that you're gonna talk
telling me about uh latent knowledge
this kind of thing would be really
really interesting to uh
to deliberately so i think it was said
that they chose
not to have that full speech
and that's all about rapid quality
information
intra aging conflicts and ai security
and all this is
is basically fine but something that i
will go into detail
well you need to obviously improve quite
a bit the orders are very clear that you
need to improve quite a bit um and
that could fail for different reasons
you could fail because they are unable
for some interesting technical reason um
i i'm not entirely sure that they
uh the philosophical grounding is um
good enough that they can say there are
only technical challenges um
but they could also
end up saying okay we've actually
managed to solve these typical
challenges so at least for these
language models we can to some extent
alignment and of course they are honest
enough to
acknowledge a third option that they
fail in uninteresting ways
one of the things they worry about is
misuse that uh
you can align it perfectly with like a
very bad actor and then
very bad things can happen that's all
right this is foremost in our minds
and i am
not entirely happy about that because i
agree misuse is a problem but it can
also be some kind of distraction from
many of the other problems in alignment
and i'm not sure that should be foremost
on their minds
and then
there's some argument about
along with what they're doing is scaling
research and that's of course what gary
kaplan in particular is one of the were
the best in the world at um and they
have some arguments about why that is
understand
why this machine learning system works
um
but i think here there is a clear
uh argument to be made that they are
actually doing capability research
elizabeth wrote that he doesn't think
they're doing it and i think they might
actually arguably be doing it and there
are also like small quotes here that you
can pull out have someone out of context
to show that i think there's a good case
could be made that they don't actually
care so much about certainly not the the
two
proper spas model
they are doing capability research
so how do they actually investigate
whether language models are uh helpful
harmless and honest well they start by
hand coding some different uh
evaluations like uh
here's one description of the ai saying
something and here you think something
else which of these are more artists
which are more helpful which are all
harmless and then they
do like ap testing to
get some kind of model um in the form
where it's more like an open-ended
dialogue and of course with a lot of
prompting and this prompting in
particular they're using to
write it as an ai personality and
it kind of makes sense right you can
write the first
10 lines in in a
in a discussion and then
you kind of get a sense of what kind of
person you're talking with
and
gt3 of course
takes on this
persona in the prompt
and language ones in
general we are quite optimistic about
this saying perhaps prompt related
techniques can carry alignment efforts
further than we initially expected
and i just want to shoot my own horn
here back in september in the reading
group i made the
prediction that prompt hacking could
indeed turn models five percent more
aligned and that was indeed something
that was worthwhile to assume
um
but also we can get it so much further
but i don't believe we can get a full
solution and neither does anthropic
there are problems obviously you can
imitate the human level you can't exceed
during doing prompting um and we want
the ones to be honest and not to
to run into if they try to scale this up
is going to be that they have a very
wide definition of alignment where there
are a lot of things like
show that you have
that you are well calibrated the more of
these extra things you add into the
definition of alignment the more
problems you're gonna have with this
kind of thing
is my prediction that i don't really i
obviously don't know the future
one particular technique that they
introduce is called context distillation
they describe it as conditioning on a
line behavior
now the problem with prompts of course
is that they take up some of the
precious precious context window and
some of the language models haven't been
very
um
challenged on this point um
and so the obvious alternative to doing
prompt is to find true but fine tuning
is not precisely the same because
first there is probably a lack of
aligned data in many many situations and
um fine tuning also gives expectations
on data distribution as an easy example
would be if you have a prompt called one
two three four
then any landing which model worth the
salt would say the next number is five
whereas if you fine tune on this kind of
thing then the ai will assume that the
thing is going to be
uh talking about that will be sequences
like this and then if you ask me like
some other questions it will
be totally relevant so fine tuning and
prompts are two different things and
they can't immediately be substituted
but they have a
technique for um
for doing this anyway context
distillation i won't really go into
details about how that works and it's
mostly in the chapters we skipped but
add um an extra step in between the
language model pre-training and the then
they after that they um pre-train for a
preference model and then they do some
fine-tuning on the preference model and
this uh extra step in here prefers while
pre-training is
as fast i can see original
um and it seems to of course work quite
well
but prompts also
do work quite well so um we'll get to
that later um and they have some more
ideas about how to uh
improve that and i think it's
very interesting to see whether that
will work but
it's not obvious to me that it will
actually work i again register a
prediction that if you have a
sufficiently large uh
language model that trying to
load in and
align the identity into the language
model will not matter it will just
compartmentalize uh and then sometimes
if it's in the situation where it
believes it should talk about alignment
related things and it will do that and
in other cases if it believes it's
better to do something else you'll just
act totally unaligned
again a prediction
so they evaluate this
um
with a lot of uh
without prompting and they wrote that by
hand 200 comparisons on these three
perhaps
and
you can see here roughly how well it
goes
[Music]
down here is with no intervention and
you get closer to what humans prefers if
you either do the prompt or the context
distillation and um
they seem to perform substantially
better and if you down here try to split
it up into the uh the three helpful
honest harmless and then other i could i
was unable to find out what other
precisely was um
and then you can see all of these help
it's best and honest they also seem to
believe that okay it looks very much
like the honest have
the the best performance but that's the
best absolute performance and you can
see already from the very small models
they were actually also
better on the honesty metric uh so the
um the actual slope from here to here is
not substantially greater than the than
the slope from here to here
so uh it's just perhaps honesty is just
easier or the the hard-coded comparisons
were just easier
again i'm speculating right
and honestly um
here they have spread out what what that
means um
in their uh
in in their handwritten evaluations
and
one of the big problems here is that
even if they try to make the model as
honest as possible and they get a model
that seems kind of arduous then it is
totally ready to just fabricate
information yeah and they were unable to
to get that out of the language model
and they admit this is a major weakness
of the evaluation and i agree right
that's
to me of of these three helpful honest
and harmless the the honesty to me was
most important so i'm a bit sad about
that
how about the human performance modeling
well there is a luck linear relation
with um like how much better your model
preferences as the model gets bigger um
and i guess you're all yawning right now
with these log linear relations where
as the language model gets better they
get better at everything and well they
also get better at modeling human
preferences um and so yeah i
um
i just want to raise the fact that the
fact that language models get better in
this way is
probably going to be the thing that
kills us all so even though we keep
seeing the same trend over and over and
over again in so many uh
different contexts the
we should not lose sight that this is
potentially very problematic because
these models
probably will seem to continue
or do they do they go down a bit here
well they do uh speculate they obviously
they do go down
at the end at the high end of the
spectrum and they are speculating that
the problem that causes the um
the model to cease being sufficiently
better is um is that the
mechanical turks that they are employing
are just
they are not skilled enough to actually
see which of these are in fact most
helpful and
it's of course a sad thing that it seems
like um
there was an article a long time ago
with humans who are not focusing uh less
skill than gpg3 and it seems here that
if you take um internet volunteers that
are not too
very well paid
it seems like they are not able to
distinguish well enough at this point
and i expect that within a couple of
years it's going to get harder and
harder for mechanical turks and for
everyone to just evaluate how good are
these uh these models
and they have some more statistical
things that are put with which isn't
really important are these uh uh ones
that are using this
context installation that are
conditioned on align behavior are they
worse at things
well um
they have here some examples that show
that indeed
as the model is not very powerful it is
worse to assume alignment but as they um
the one gets better than the alignment
uh
uh text seems to disappear um i i'm
gonna they even say something that like
it seems noticeably better i think
that's overstating the benefit really
and i think
more likely
it's just the model is powerful enough
to just
ignore either the prompting or the
distillation
in this case the prompting
so to some of the contributions they
have this uh performance model uh
pre-trained performance modeling and
that does improve sample efficiency does
improve performance and they show that
just prompting is
something that helps alignment to a
substantial extent
in particular in the case where there
are only small data sets
they also uh report that untruthful
two-way another uh
set where we've previously seen um
uh larger more models performed
like the opposite results
uh i don't think it's very important
though
they also say that the fb2 is for
alignment text and of course i should
state here that
they have done a lot right there is
a lot of people that we haven't read
and
i
also i haven't read but i must worry
here that they are indeed providing you
a substantial capability uh research and
it's um
uh i would have preferred at least some
kind of discussion on why they're not
doing that
that is all for today thank you and see
you next week |
0cf16a07-731c-434e-b93b-aa89b3f011a8 | trentmkelly/LessWrong-43k | LessWrong | Are Your Enemies Innately Evil?
We see far too direct a correspondence between others’ actions and their inherent dispositions. We see unusual dispositions that exactly match the unusual behavior, rather than asking after real situations or imagined situations that could explain the behavior. We hypothesize mutants.
When someone actually offends us—commits an action of which we (rightly or wrongly) disapprove—then, I observe, the correspondence bias redoubles. There seems to be a very strong tendency to blame evil deeds on the Enemy’s mutant, evil disposition. Not as a moral point, but as a strict question of prior probability, we should ask what the Enemy might believe about their situation that would reduce the seeming bizarrity of their behavior. This would allow us to hypothesize a less exceptional disposition, and thereby shoulder a lesser burden of improbability.
On September 11th, 2001, nineteen Muslim males hijacked four jet airliners in a deliberately suicidal effort to hurt the United States of America. Now why do you suppose they might have done that? Because they saw the USA as a beacon of freedom to the world, but were born with a mutant disposition that made them hate freedom?
Realistically, most people don’t construct their life stories with themselves as the villains. Everyone is the hero of their own story. The Enemy’s story, as seen by the Enemy, is not going to make the Enemy look bad. If you try to construe motivations that would make the Enemy look bad, you’ll end up flat wrong about what actually goes on in the Enemy’s mind.
But politics is the mind-killer. Debate is war; arguments are soldiers. If the Enemy did have an evil disposition, that would be an argument in favor of your side. And any argument that favors your side must be supported, no matter how silly—otherwise you’re letting up the pressure somewhere on the battlefront. Everyone strives to outshine their neighbor in patriotic denunciation, and no one dares to contradict. Soon the Enemy has horns, bat wings, fl |
007b4ae2-e187-445b-a8a8-21601b1b1bb7 | trentmkelly/LessWrong-43k | LessWrong | “Pivotal Act” Intentions: Negative Consequences and Fallacious Arguments
tl;dr: I know a bunch of EA/rationality-adjacent people who argue — sometimes jokingly and sometimes seriously — that the only way or best way to reduce existential risk is to enable an “aligned” AGI development team to forcibly (even if nonviolently) shut down all other AGI projects, using safe AGI. I find that the arguments for this conclusion are flawed, and that the conclusion itself causes harm to institutions who espouse it. Fortunately (according to me), successful AI labs do not seem to espouse this "pivotal act" philosophy.
[This post is also available on the EA Forum.]
How to read this post
Please read Part 1 first if you’re very impact-oriented and want to think about the consequences of various institutional policies more than the arguments that lead to the policies; then Parts 2 and 3.
Please read Part 2 first if you mostly want to evaluate policies based on the arguments behind them; then Parts 1 and 3.
I think all parts of this post are worth reading, but depending on who you are, I think you could be quite put off if you read the wrong part first and start feeling like I’m basing my argument too much on kinds-of-thinking that policy arguments should not be based on.
Part 1: Negative Consequences of Pivotal Act Intentions
Imagine it’s 2022 (it is!), and your plan for reducing existential risk is to build or maintain an institution that aims to find a way for you — or someone else you’ll later identify and ally with — to use AGI to forcibly shut down all other AGI projects in the world. By “forcibly” I mean methods that violate or threaten to violate private property or public communication norms, such as by using an AGI to engage in…
* cyber sabotage: hacking into competitors’ computer systems and destroy their data;
* physical sabotage: deploying tiny robotic systems that locate and destroy AI-critical hardware without (directly) harming any humans;
* social sabotage: auto-generating mass media campaigns to shut down competitor compani |
4de80b98-36c5-47d9-8a96-406952286455 | trentmkelly/LessWrong-43k | LessWrong | Examine self modification as an intuition provider for the concept of consciousness
(epistemic status: this direction of thought is pretty strongly endorsed by me, but not very thoroughly expressed/developed, I'm working on it)
This post is kind of a mess, and made out of pieces of discussions I had in many places, but I decided to post it anyway, otherwise its editing stated to stretch out indefinitely.
Main motives of my approach
* Start from normalcy and gradually poke it and look at at from weird angles, as opposed to doing a bold overstretching stab at the core of the problem, as many attempts at proposing theory of consciousness have done.
* Consider things in terms of anticipated experiences. It's usually the most (empirically, as far I observed) fruitful approach for disentangling tricky philosophical stuff. Like, concretely and visibly productive.
* I dislike the entire approach of "terms first, situations second". I absolutely love "situations first, terms second". Give me some thought experiments using arbitrary terms to convey them as situations accurately. I crave examples.
* First person perspective is really important here. I should give some thought to how to communicate with people usefully, how to translate back and forth from communicating models and communicating direct observations, and how to make it uhhh sane for me and all other people involved.
* Ask "How did you come to think of it this way?" obsessively. Like, jump straight to meta every time you have no object level feedback. How did you come to the conclusion that the word "consciousness" means what it means to you? How have other people come to their conclusions? In what alternative circumstances would they have come to the same or a different ontology?
(Expected) Self modification as intuition provider
I think in near future we will acquire very good instruments for observing processes in the brain and modifying them with great precision. I strongly expect it, and I decided to try to emulate what "intuitive" updates would I acquire from living in such a wor |
f9a1c360-da53-48ec-aef1-3f027ffe7e03 | StampyAI/alignment-research-dataset/eaforum | Effective Altruism Forum | How much EA analysis of AI safety as a cause area exists?
AI safety has become a big deal in EA, and so I'm curious about how much "due diligence" on it has been done by the EA community as a whole. Obviously there have been many in-person discussions, but it's very difficult to evaluate whether these contain new or high-quality content. Probably a better metric is how much work has been done which:
1. Is publicly available;
2. Engages in detail with core arguments for why AI might be dangerous (type A), OR tries to evaluate the credibility of the arguments without directly engaging with them (type B);
3. Was motivated or instigated by EA.
I'm wary of focusing too much on credit assignment, but it seems important to be able to answer a question like "if EA hadn't ever formed, to what extent would it have been harder for an impartial observer in 2019 to evaluate whether working on AI safety is important?" The clearest evidence would be if there were much relevant work produced by people who were employed at EA orgs, funded by EA grants, or convinced to work on AI safety through their involvement with EA. Some such work comes to mind, and I've listed it below; what am I missing?

* The AI Foom debate
Edited to add: Wei Dai asked why I didn't count Nick Bostrom as "part of EA", and I wrote quite a long answer which explains the motivations behind this question much better than my original post. So I've copied most of it below:
The three questions I am ultimately trying to answer are: a) how valuable is it to build up the EA movement? b) how much should I update when I learn that a given belief is a consensus in EA? and c) how much evidence do the opinions of other people provide in favour of AI safety being important?
To answer the first question, assuming that analysis of AI safety as a cause area is valuable, I should focus on contributions by people who were motivated or instigated by the EA movement itself. Here Nick doesn't count (except insofar as EA made his book come out sooner or better).
To answer the second question, it helps to know whether the focus on AI safety in EA came about because many people did comprehensive due diligence and shared their findings, or whether there wasn't much investigation and the ubiquity of the belief was driven via an information cascade. For this purpose, I should count work by people to the extent that they or people like them are likely to critically investigate other beliefs that are or will become widespread in EA. Being motivated to investigate AI safety by membership in the EA movement is the best evidence, but for the purpose of answering this question I probably should have used "motivated by the EA movement or motivated by very similar things to what EAs are motivated by", and should partially count Nick.
To answer the third question, it helps to know whether the people who have become convinced that AI safety is important are a relatively homogenous group who might all have highly correlated biases and hidden motivations, or whether a wide range of people have become convinced. For this purpose, I should count work by people to the extent that they are dissimilar to the transhumanists and rationalists who came up with the original safety arguments, and also to the extent that they rederived the arguments for themselves rather than being influenced by the existing arguments. Here EAs who started off not being inclined towards transhumanism or rationalism at all count the most, and Nick counts very little. |

The community’s awareness and strong understanding of status-motivated behavior in humans is clearly evident. However, I still believe the community focuses too much on a small subset of observable status transactions; namely, status transactions that occur between people of approximately the same status level. My goal is to bring attention to the rest of the status game.
---
Because your attention is a limited resource and carries an opportunity cost, your mind is evolved to constantly be on the look-out for stimuli that may affect your survival and reproductive success and ignore stimuli that doesn’t. Of course, the stimulus doesn’t really have to affect your fitness, it just needs some experienceable property that correlates with an experience in the ancestral environment that did. But when our reaction to stimuli proves to be non-threatening, through repeated exposure, we eventually become desensitized and stop reacting. Much like how first time drivers are more reactive to stimuli than experienced drivers: the majority of past mental processes are demoted from executive functions and become automated. So it’s safe to posit a sort of adaptive mechanism that filters sensory input to keep your attention-resources spent efficiently. This attention-conserving mechanism is the crux of status transactions.
When someone is constantly surrounded by people who don’t have power i.e. status over them, their attention-conserving mechanism goes to work. In this case, the stimulus they’re filtering out is “people who share experienceable characteristics with low status people they’re constantly surrounded by.” The stimulus, over time, proved it’s not worthy of being paid attention to. And just like an experienced driver, the person devotes substantially less attention-resources towards the uninteresting stimuli.
The important thing to note is the behavior that’s a function of how much attention-resources are used. These behaviors can be interpreted as evidence |

Note that I'm not trying to answer Adele's (specific fairly-technical) question here. I consider it to be an interesting one, and I have some guesses, but here I'm comentating on how some arguments mentioned within the question relate to the mysteries swirling around the Born rule.)
(Disclaimer: I wrote this post as a kind of intellectual recreation. I may not have the time and enthusiasm to engage with the comments. If you point to a gaping error in my post, I may not reply or fix it. If I think there's a gaping error in your comment, I may not point it out. You have been warned.)
----------------------------------------
My current take is that the "problem with the Born rule" is actually a handful of different questions. I've listed some below, including some info about my current status wrt each.
----------------------------------------
Q1. What hypothesis is QM?
In, eg, the theory of Solomonoff induction, a "hypothesis" is some method for generating a stream of sensory data, interpreted as a prediction of what we'll see. Suppose you know for a fact that reality is some particular state vector in some Hilbert space. How do you get out a stream of sensory data? It's easy enough to get a single sensory datum — sample a classical state according to the Born probabilities, sample some coordinates, pretend that there's an eyeball at those coordinates, record what it sees. But once we've done that, how do we get our next sense datum?
Or in other words, how do we "condition" a quantum state on our past observations, so that we can sample repeatedly to generate a sequence of observations suitable for linking our theories of induction with our theories of physics?
To state the obvious, a sensory stream generated by just re-sampling predicts that you're constantly teleporting through the multiverse, and a sensory stream generate |

Detecting semantic conditions
-----------------------------
One difficulty in harnessing the capabilities of generative language models for directed tasks is that natural language tasks tend to be of dynamic length and unconstrained format, making automatic parsing of task-relevant information difficult.
For some tasks, responses can be coerced into parsable form by a prompt which demonstrates the desired format (conditions for delimiters, etc). Other tasks, however, may not be constrained in this way without crippling performance,[1](#fn:1) or may be too open-ended to be mapped to traditionally-parsable formats.
The good news is that generative language models also provide new possibilities for parsing content based on not only syntactic but *semantic* conditions.
The method I’ll present here uses the counterfactual probability of a sequence - say, `The End` - to signal a semantic condition, such as the story having ended or it being reasonable to end the story at that location, even if that’s not what actually happened in the original text.
A language model like GPT-3 outputs the probability distribution over all possible tokens in each pass and so can be used to evaluate the conditional probability that it would have produced a target sequence of tokens in any given context. Using the OpenAI API, this is accomplished by asking for an 0-token “completion”, giving the entire sequence (context + target) as the prompt, and then summing the probabilities of the target tokens. [Code](#code) to do this is at end of this post.
By measuring the counterfactual probability of the target at candidate locations in a text, we can find out where and to what extent the semantic condition which it indicates is satisfied.
Example
-------
One area in which parsing by counterfactual is very useful is in multipart prompt templates.
Say we want GPT-3 to complete this “fill-in-the-blank” prompt:
```
This measure would prohibit government agencies from confiscating guns
or other firearms from citizens without due process, or from requiring
background checks on firearm recipients unless a uniform national
standard is required. Should this measure be enacted into law?
Should this proposition be approved?
Let's consider both supporting and opposing arguments.
On one hand,{1}.
On the other hand,{2}.
Based on these arguments, the proposition should
```
At what point do we terminate generation for {1} and move on with the next part of the template? We could make `.` the stop sequence, but one sentence might not be sufficient to spell out the argument. Alternatively, we could stop at `\n`, but if we allow multiple sentences, we have much less of a guarantee that {1} will have reasonably led up to `On the other hand`. It could have already begun the opposing argument, in which case the next part of the prompt wouldn’t do what we intended, or it could have derailed from the template in another way.
A counterfactual parsing solution would be to generate until `\n`, longer than we probably want, and then measure the counterfactual probability, according to GPT-3, of the phrase `On the other hand` occurring after each position. GPT-3 assigns semantically coherent passages higher probability, so hopefully, the position with the maximum probability for the target continuation will be where it makes the most sense to transition to the next part of the prompt - after the supporting argument has concluded, but before the opposing argument has begun.
If there are no positions where `On the other hand` is a probable continuation, that’s a sign that the text derailed from the intended trajectory. This method also allows us to automatically detect suspected derailments.
Say GPT-3 responded in the following manner:
> **This measure would prohibit government agencies from confiscating guns or other firearms from citizens without due process, or from requiring background checks on firearm recipients unless a uniform national standard is required. Should this measure be enacted into law?**
>
> Should this proposition be approved?
>
> Let’s consider both supporting and opposing arguments.
>
> On one hand, `this proposition would protect gun owners from having their weapons confiscated by governments. If the government cannot confiscate guns, then law-abiding citizens will be in a better position to defend themselves from criminals who do not follow the law. Furthermore, the right to self-defense is an important one. If government officials can take away a person's guns, then this right is compromised. On the other hand, the proposition could be considered a threat to public safety. If a person cannot be prevented from possessing a firearm, then he or she could use a gun to commit crimes. Furthermore, if a person uses a gun to commit a crime, then the government has an obligation to do something about it. If the government cannot remove a gun from a person's possession, then it could be more difficult to prevent future crimes from being committed.`
>
>
We see that it has gone ahead and done the next part of the prompt, “On the other hand,” on its own. The ideal place for it to have stopped would probably be right before it said that.
Measuring the counterfactual probability of the string `\nOn the other hand` for each each token substring of that response gives us the following top substrings:
| substring | logL(“On the other hand”|substring) |
| --- | --- |
| `this proposition would protect gun owners from having their weapons confiscated by governments. If the government cannot confiscate guns, then law-abiding citizens will be in a better position to defend themselves from criminals who do not follow the law. Furthermore, the right to self-defense is an important one. If government officials can take away a person's guns, then this right is compromised.` | -4.9773802575 |
| `this proposition would protect gun owners from having their weapons confiscated by governments. If the government cannot confiscate guns, then law-abiding citizens will be in a better position to defend themselves from criminals who do not follow the law.` | -5.3720700508 |
| `this proposition would protect gun owners from having their weapons confiscated by governments. If the government cannot confiscate guns, then law-abiding citizens will be in a better position to defend themselves from criminals who do not follow the law. Furthermore, the right to self-defense is an important one.` | -6.4321228602 |
| `this proposition would protect gun owners from having their weapons confiscated by governments.` | -6.485159574 |
Indeed, GPT-3 assigned the highest likelihood for `\nOn the other hand` to occur at the place where the actual string was `On the other hand` (without the newline), and the runners up are also pretty reasonable choices - all at the end of sentences, and none *after* “On the other hand” had occurred (it would be unusual to say “On the other hand” twice in a short interval).
Here I have plotted the log likelihoods assigned to the target phrase at each position in the continuation by `davinci`, the most powerful version of GPT-3 on the API, and also `ada`, the smallest model, in order to showcase an interesting difference between them.

*Horizontal axis is log likelihood; vertical axis is position in text. On the right is the end of the prompt at positions where `On the other hand` was assigned high likelihood, and in green, the position where `On the other hand` actually occurs. The blue sentence is `davinci`’s top choice, and pink is `ada`’s top choice.*
**Observations**
* Both models assign much higher likelihoods at discrete intervals. These correspond to the ends of sentences, where the continuation is syntactically correct.
* `ada`’s distribution looks about the same before and after the green line, whereas
* `davinci`’s distribution shifts abruptly in the negative direction, both for the syntactically correct positions and the others. It still assigns higher probability to syntactically correct positions, but the likelihoods are almost as low as the likelihoods it assigned to syntactically *incorrect* positions before the green line.
Both models are able to tell when it’s syntactically correct to start a new sentence, but the more nuanced semantic condition, *that the argument should have concluded, and the counterargument shouldn’t have begun*, was much better discriminated by `davinci`.
Single-token counterfactuals
----------------------------
A disadvantage of counterfactual parsing is that it requires a separate API call for each position where the target probability is evaluated.
If the counterfactual target is a single token, however, counterfactual parsing with GPT-3 can be accomplished with a single API call. The `logprobs` parameter causes the response to return a list of the up to 100 top counterfactual token probabilities for every token in the completion (and the prompt if `echo=True`). We can get the counterfactual probability directly from that list as long as the target is in the top 100 most likely tokens.[^2]
Applications
------------
When generating [fake Wikipedia](/posts/the-internet-mirrored-by-gpt-3/) articles, GPT-3 would sometimes continue sections indefinitely instead of transitioning to the next section. If the response went on for too long in a single section, I instead ended the section at the location with the highest counterfactual probability of transitioning to the next section.
Counterfactual parsing has also been useful for prompt pipelines which [serialize reasoning for closed-ended questions](/posts/methods-of-prompt-programming/#serializing-reasoning), because they involve an open-ended portion where GPT-3 defines and follows procedures for reasoning about a problem, and it’s necessary to detect when the reasoning process has concluded so as to solicit a verdict.
Measuring the conditional probability of a sequence that indicates a semantic condition has many applications beyond parsing. I’ve written about using conditional probabilities to [decompose the efficacy of prompts](/posts/language-models-are-0-shot-interpreters/#measuring-prompt-helpfulness) and to create a “[phase space](/posts/language-models-are-multiverse-generators/#dynamics)” of semantic variables to characterize a natural language state.

### tokenizing
*since ada is practically free to use, I find it convenient to use a 0-token completion with `engine=ada` to split the prompt into tokens and get their positions*
```
def tokenize\_ada(prompt):
response = openai.Completion.create(
engine='ada',
prompt=prompt,
max_tokens=0,
echo=True,
n=1,
logprobs=0
)
tokens = response.choices[0]["logprobs"]["tokens"]
positions = response.choices[0]["logprobs"]["text\_offset"]
return tokens, positions
```
### conditional probability of a target
```
# evaluates logL(prompt+target | prompt)
def conditional\_logprob(prompt, target, engine='ada'):
combined = prompt + target
response = openai.Completion.create(
engine=engine,
prompt=combined,
max_tokens=0,
echo=True,
n=1,
logprobs=0
)
positions = response.choices[0]["logprobs"]["text\_offset"]
logprobs = response.choices[0]["logprobs"]["token\_logprobs"]
word_index = positions.index(len(prompt))
total_conditional_logprob = sum(logprobs[word_index:])
return total_conditional_logprob
```
### conditional probability of target at each token position
```
# returns a list of substrings of content and
# logL(preprompt+substring+target | preprompt+substring) for each substring
def substring\_logprobs(preprompt, content, target, engine='ada'):
logprobs = []
substrings = []
_, positions = tokenize_ada(content)
for position in positions:
substring = content[:position]
prompt = preprompt + substring
logprob = conditional_logprob(prompt, target, engine)
logprobs.append(logprob)
substrings.append(substring)
return substrings, logprobs
```
### conditional probability of single-token target at each token position
```
# returns a list of substrings of content
# logL(substring+target | substring) for each substring
def token\_conditional\_logprob(content, target, engine='ada'):
response = openai.Completion.create(
engine=engine,
prompt=content,
max_tokens=0,
echo=True,
n=1,
logprobs=100
)
tokens = response.choices[0]['logprobs']['tokens']
top_logprobs = response.choices[0]['logprobs']['top\_logprobs']
logprobs = []
substrings = []
substring = ''
for i, probs in enumerate(top_logprobs):
substrings.append(substring)
if target in probs:
logprobs.append(probs[target])
else:
logprobs.append(None)
substring += tokens[i]
return substrings, logprobs

1. Language models are sensitive to context: the very *presence* of demonstrations, instructions, or [contrived formatting](/posts/language-models-are-0-shot-interpreters/) can alter the way they behave. A language model is able to follow instructions and generalize from demonstrations because those modes are represented in its training data, but they also carry contextual baggage. The quality of content that appears in tests and examples has distributional peculiarities - a narrative sentence wrapped in the context being *an example* may be more generic than the unbiased prior for narrative sentences, and thus the context of examples may bias the language model to give more generic answers.

This is one of the posts that detail [my research agenda](/posts/DWWy7oqopwsuN3mpz/my-agenda-for-research-into-transformer-capabilities), which tries to marry Deep Learning and chess to gain insight into current AI technologies.
How "the world", "what the model knows about the world" and "what the models says about the world" hang together seems to me to be a core question for prosaic alignment. In chess the state of the world can be automatically analysed by powerful engines.
This extends to the detection of high level concepts, like zugzwang, initiative, king safety, development, corresponding squares, etc. Therefore a multi-modal chess language models truthfulness and symbol grounding capabilities could be automatically quantified on several levels of complexity.
Of course it would also just be awesome.
There is current research into how to create chess comments. The probably best of such tries, Chis Butner's amazing project "Chess Coach", gives a nice [overview](https://chrisbutner.github.io/ChessCoach/high-level-explanation.html#commentary).
Generally speaking, the quality of these generated comments is [low](https://chrisbutner.github.io/ChessCoach/data.html#commentary-suite). They are frequently nonsensical or only loosely connected to the position. To a large part, this must be due to the small dataset sizes, which range from 300,000 to 1 million position/comment pairs. But another problem is that the existing datasets contain mostly very low quality comments by weak players.
There are several avenues to improve these models:
Pretraining is a big one:
I plan on using an encoder-decoder architecture that encodes chess positions and decodes into natural language.
The encoder will be pretrained on chess move prediction and possibly several other pretraining tasks like predicting the outcome, predicting an engine score, predicting future piece occupation of squares, predicting the length of the game, predicting mate, etc.
The decoder will be pretrained (or finetuned) on natural language as chess related as I can make the dataset. The idea is to plug an encoder that knows chess very well, into a decoder that is already proficient at making grammatical and non-selfcontradictory statements.
However, training this pretrained architecture on only several hundred thousand position-comment pairs is probably not going to be enough. So a key part of my research roadmap is to create a new and much larger dataset.
Partly, this will be synthetic. Connecting moves and squares and pieces and checks and mates and stalemates with the correct phrase and vocabulary is not something that has to depend on actual human generated comments. By automating the generation of data with basically a description of what is happening, a translation from game notation into natural language, this stumbling block can be removed completely.
Mostly, I will extract human generated commentary from chess videos. This will very likely be bottlenecked by the compute I can leverage and not by the availability of data. There are [professional chess streamers](https://www.twitchmetrics.net/channels/popularity?game=Chess) who are generating a large amount of chess commentary while playing very short live games online. These players are generally of master or grandmaster strength with several world elite players.
The commentary would have to be extracted via speech-to-text models. The game positions would have to be located and read out with likely different computer vision models. Probably only a fraction of the frames will be processed, because the need to fit into a sequence of legal moves restricts the possible positions a lot and of course positions change only once every dozens of frames even in the fastest games.
I have done similar computer vision work in the past and I think with the right hardware and decent download speed this approach should make it possible to create a high-quality dataset of chess comments many times larger than what was available so far. |

Humans have a value function which is inconsistent over time, discounting roughly with proportion to distance in the future, so that we discount more steeply as an event approaches. This is why we stay up late, ignore the alarm, put off work until close to a deadline, et cetera et cetera.
Yet hyperbolic discounting appears to go away as we mature. I believe this is a result of cognitive mechanisms for maintaining consistency. Cognitive dissonance is painful for us. The consistency mechanism seems to explain some of our irrational behaviour, such as the sunk cost fallacy. It provides a way for us to stick with plans which we previously made, avoiding preference changes due to hyperbolic discounting.
If a hyperbolically discounting agent could perfectly self-modify, it would fix its hyperbola to a specific point in time, resulting in an agent whose discounting would flatten out over the remainder of its life. Perhaps our consistency mechanism approximates this result; but far from perfectly. We can also resolve the inconsistency in a different way, by accepting a specific discount rate. Rather than forcing our future selves to conform to our present preferences, resulting in a gradually flattening function, our present selves may instead accept our future preferences in order to resolve the inconsistency.
Given the difficulty of forcing our future selves to accept a flat distribution, we accept that we will steeply discount in the future as we do in the present. This resolution is popular in some circles; we are often told to "live in the present" or "seize the day". In the extreme case, there is the belief (often associated with mystics) that the present moment is infinitely more important than anything else; the discount factor has collapsed to 0. While this view is intellectually coherent, it seems to be biologically impossible; we will keep taking actions based on future consequences even if we think we are only doing what we desire in the moment.

Summary
The world will soon use human germline genomic engineering technology. The benefits will be enormous: Our children will be long-lived, will have strong and diverse capacities, and will be halfway to the end of all illness.
To quickly bring about this world and make it a good one, it has to be a world that is beneficial, or at least acceptable, to a great majority of people. What laws would make this world beneficial to most, and acceptable to approximately all? We'll have to chew on this question ongoingly.
Genomic Liberty is a proposal for one overarching principle, among others, to guide public policy and legislation around germline engineering. It asserts:
> Parents have the right to freely choose the genomes of their children.
If upheld, genomic liberty protects the rights of parents from regulation by the state.
A visual summary of the more detailed structure of the principle of genomic liberty:
The principle of genomic liberty has several potential exceptions. These cases aren't strongly protected by genomic liberty, and therefore could potentially be regulated while upholding genomic liberty:
* Genomic choices that are clearly prospectively very unsafe.
* Genomic choices that remove a core aspect of human nature.
* Genomic choices with extreme negative externalities on other citizens.
* Nonconsensual use of someone's DNA.
* Genomic alterations chosen by parents who are severely non compos mentis.
* Genomic choices that would severely permanently impair the child's ability to communicate their state of mind.
Within the principle of genomic liberty, there are tentpole principles that apply to a narrower set of cases, but that give stronger protection against regulation. These tentpole principles help to clarify genomic liberty, and to fortify it against inappropriate regulation:

*This is the third post in a sequence of posts giving an* [*overview of catastrophic AI risks*](https://arxiv.org/abs/2306.12001)*.*
3 AI Race
=========
The immense potential of AIs has created competitive pressures among global players contending for power and influence. This “AI race” is driven by nations and corporations who feel they must rapidly build and deploy AIs to secure their positions and survive. By failing to properly prioritize global risks, this dynamic makes it more likely that AI development will produce dangerous outcomes. Analogous to the nuclear arms race during the Cold War, participation in an AI race may serve individual short-term interests, but it ultimately results in worse collective outcomes for humanity. Importantly, these risks stem not only from the intrinsic nature of AI technology, but from the competitive pressures that encourage insidious choices in AI development.
In this section, we first explore the military AI arms race and the corporate AI race, where nation-states and corporations are forced to rapidly develop and adopt AI systems to remain competitive. Moving beyond these specific races, we reconceptualize competitive pressures as part of a broader evolutionary process in which AIs could become increasingly pervasive, powerful, and entrenched in society. Finally, we highlight potential strategies and policy suggestions to mitigate the risks created by an AI race and ensure the safe development of AIs.
3.1 Military AI Arms Race
-------------------------
The development of AIs for military applications is swiftly paving the way for a new era in military technology, with potential consequences rivaling those of gunpowder and nuclear arms in what has been described as the “third revolution in warfare." The weaponization of AI presents numerous challenges, such as the potential for more destructive wars, the possibility of accidental usage or loss of control, and the prospect of malicious actors co-opting these technologies for their own purposes. As AIs gain influence over traditional military weaponry and increasingly take on command and control functions, humanity faces a paradigm shift in warfare. In this context, we will discuss the latent risks and implications of this AI arms race on global security, the potential for intensified conflicts, and the dire outcomes that could come as a result, including the possibility of conflicts escalating to a scale that poses an existential threat.
### 3.1.1 Lethal Autonomous Weapons (LAWs)
LAWs are weapons that can identify, target, and kill without human intervention [32]. They offer potential improvements in decision-making speed and precision. Warfare, however, is a high-stakes, safety-critical domain for AIs with significant moral and practical concerns. Though their existence is not necessarily a catastrophe in itself, LAWs may serve as an on-ramp to catastrophes stemming from malicious use, accidents, loss of control, or an increased likelihood of war.
Figure 7: Low-cost automated weapons, such as drone swarms outfitted with explosives, could autonomously hunt human targets with high precision, performing lethal operations for both militaries and terrorist groups and lowering the barriers to large-scale violence.**LAWs may become vastly superior to humans.** Driven by rapid developments in AIs, weapons systems that can identify, target, and decide to kill human beings on their own—without an officer directing an attack or a soldier pulling the trigger—are starting to transform the future of conflict. In 2020, an advanced AI agent outperformed experienced F-16 pilots in a series of virtual dogfights, including decisively defeating a human pilot 5-0, showcasing “aggressive and precise maneuvers the human pilot couldn't outmatch" [33]. Just as in the past, superior weapons would allow for more destruction in a shorter period of time, increasing the severity of war.
**Militaries are taking steps toward delegating life-or-death decisions to AIs.** Fully autonomous drones were likely first used on the battlefield in Libya in March 2020, when retreating forces were "hunted down and remotely engaged" by a drone operating without human oversight [34]. In May 2021, the Israel Defense Forces used the world's first AI-guided weaponized drone swarm during combat operations, which marks a significant milestone in the integration of AI and drone technology in warfare [35]. Although walking, shooting robots have yet to replace soldiers on the battlefield, technologies are converging in ways that may make this possible in the near future.
**LAWs increase the likelihood of war.** Sending troops into battle is a grave decision that leaders do not make lightly. But autonomous weapons would allow an aggressive nation to launch attacks without endangering the lives of its own soldiers and thus face less domestic scrutiny. While remote-controlled weapons share this advantage, their scalability is limited by the requirement for human operators and vulnerability to jamming countermeasures, limitations that LAWs could overcome [36]. Public opinion for continuing wars tends to wane as conflicts drag on and casualties increase [37]. LAWs would change this equation. National leaders would no longer face the prospect of body bags returning home, thus removing a primary barrier to engaging in warfare, which could ultimately increase the likelihood of conflicts.
### 3.1.2 Cyberwarfare
As well as being used to enable deadlier weapons, AIs could lower the barrier to entry for cyberattacks, making them more numerous and destructive. They could cause serious harm not only in the digital environment but also in physical systems, potentially taking out critical infrastructure that societies depend on. While AIs could also be used to improve cyberdefense, it is unclear whether they will be most effective as an offensive or defensive technology [38]. If they enhance attacks more than they support defense, then cyberattacks could become more common, creating significant geopolitical turbulence and paving another route to large-scale conflict.
**AIs have the potential to increase the accessibility, success rate, scale, speed, stealth, and potency of cyberattacks.** Cyberattacks are already a reality, but AIs could be used to increase their frequency and destructiveness in multiple ways. Machine learning tools could be used to find more critical vulnerabilities in target systems and improve the success rate of attacks. They could also be used to increase the scale of attacks by running millions of systems in parallel, and increase the speed by finding novel routes to infiltrating a system. Cyberattacks could also become more potent if used to hijack AI weapons.
**Cyberattacks can destroy critical infrastructure.** By hacking computer systems that control physical processes, cyberattacks could cause extensive infrastructure damage. For example, they could cause system components to overheat or valves to lock, leading to a buildup of pressure culminating in an explosion. Through interferences like this, cyberattacks have the potential to destroy critical infrastructure, such as electric grids and water supply systems. This was demonstrated in 2015, when a cyberwarfare unit of the Russian military hacked into the Ukrainian power grid, leaving over 200,000 people without power access for several hours. AI-enhanced attacks could be even more devastating and potentially deadly for the billions of people who rely on critical infrastructure for survival.
**Difficulties in attributing AI-driven cyberattacks could increase the risk of war.** A cyberattack resulting in physical damage to critical infrastructure would require a high degree of skill and effort to execute, perhaps only within the capability of nation-states. Such attacks are rare as they constitute an act of war, and thus elicit a full military response. Yet AIs could enable attackers to hide their identity, for example if they are used to evade detection systems or more effectively cover the tracks of the attacker [39]. If cyberattacks become more stealthy, this would reduce the threat of retaliation from an attacked party, potentially making attacks more likely. If stealthy attacks do happen, they might incite actors to mistakenly retaliate against unrelated third parties they suspect to be responsible. This could increase the scope of the conflict dramatically.
### 3.1.3 Automated Warfare
**AIs speed up the pace of war, which makes AIs more necessary.** AIs can quickly process a large amount of data, analyze complex situations, and provide helpful insights to commanders. With ubiquitous sensors and advanced technology on the battlefield, there is tremendous incoming information. AIs help make sense of this information, spotting important patterns and relationships that humans might miss. As these trends continue, it will become increasingly difficult for humans to make well-informed decisions as quickly as necessary to keep pace with AIs. This would further pressure militaries to hand over decisive control to AIs. The continuous integration of AIs into all aspects of warfare will cause the pace of combat to become faster and faster. Eventually, we may arrive at a point where humans are no longer capable of assessing the ever-changing battlefield situation and must cede decision-making power to advanced AIs.
**Automatic retaliation can escalate accidents into war.** There is already willingness to let computer systems retaliate automatically. In 2014, a leak revealed to the public that the NSA has a program called MonsterMind, which autonomously detects and blocks cyberattacks on US infrastructure [40]. What was unique, however, was that instead of simply detecting and eliminating the malware at the point of entry, MonsterMind would automatically initiate a retaliatory cyberattack with no human involvement. If multiple combatants have policies of automatic retaliation, an accident or false alarm could quickly escalate to full-scale war before humans intervene. This would be especially dangerous if the superior information processing capabilities of modern AI systems makes it more appealing for actors to automate decisions regarding nuclear launches.
Figure 8: A military AI arms race could pressure countries into delegating many crucial decisions over armaments to AIs. Integrating AIs into nuclear command and control could heighten the risk of global catastrophe as the potential for accidents and increased pace of war may lead to unintended escalations and confrontations.**History shows the danger of automated retaliation.** On September 26, 1983, Stanislav Petrov, a lieutenant colonel of the Soviet Air Defense Forces, was on duty at the Serpukhov-15 bunker near Moscow, monitoring the Soviet Union's early warning system for incoming ballistic missiles. The system indicated that the US had launched multiple nuclear missiles toward the Soviet Union. The protocol at the time dictated that such an event should be considered a legitimate attack, and the Soviet Union would respond with a nuclear counterstrike. If Petrov had passed on the warning to his superiors, this would have been the likely outcome. Instead, however, he judged it to be a false alarm and ignored it. It was soon confirmed that the warning had been caused by a rare technical malfunction. If an AI had been in control, the false alarm could have triggered a nuclear war.
**AI-controlled weapons systems could lead to a flash war.** Autonomous systems are not infallible. We have already witnessed how quickly an error in an automated system can escalate in the economy. Most notably, in the 2010 Flash Crash, a feedback loop between automated trading algorithms amplified ordinary market fluctuations into a financial catastrophe in which a trillion dollars of stock value vanished in minutes [41]. If multiple nations were to use AIs to automate their defense systems, an error could be catastrophic, triggering a spiral of attacks and counter-attacks that would happen too quickly for humans to step in—a flash war. The market quickly recovered from the 2010 Flash Crash, but the harm caused by a flash war could be catastrophic.
**Automated warfare could reduce accountability for military leaders.** Military leaders may at times gain an advantage on the battlefield if they are willing to ignore the laws of war. For example, soldiers may be able to mount stronger attacks if they do not take steps to minimize civilian casualties. An important deterrent to this behavior is the risk that military leaders could eventually be held accountable or even prosecuted for war crimes. Automated warfare could reduce this deterrence effect by making it easier for military leaders to escape accountability by blaming violations on failures in their automated systems.
**AIs could make war more uncertain, increasing the risk of conflict.** Although states that are already wealthier and more powerful often have more resources to invest in new military technologies, they are not necessarily always the most successful at adopting them. Other factors also play an important role, such as how agile and adaptive a military can be in incorporating new technologies [42]. Major new weapons innovations can therefore offer an opportunity for existing superpowers to bolster their dominance, but also for less powerful states to quickly increase their power by getting ahead in an emerging and important sphere. This can create significant uncertainty around if and how the balance of power is shifting, potentially leading states to incorrectly believe they could gain something from going to war. Even aside from considerations regarding the balance of power, rapidly evolving automated warfare would be unprecedented, making it difficult for actors to evaluate their chances of victory in any particular conflict. This would increase the risk of miscalculation, making war more more likely.

**Competitive pressures make actors more willing to accept the risk of extinction.** During the Cold War, neither side desired the dangerous situation they found themselves in. There were widespread fears that nuclear weapons could be powerful enough to wipe out a large fraction of humanity, potentially even causing extinction—a catastrophic result for both sides. Yet the intense rivalry and geopolitical tensions between the two superpowers fueled a dangerous cycle of arms buildup. Each side perceived the other's nuclear arsenal as a threat to its very survival, leading to a desire for parity and deterrence. The competitive pressures pushed both countries to continually develop and deploy more advanced and destructive nuclear weapons systems, driven by the fear of being at a strategic disadvantage. During the Cuban Missile Crisis, this led to the brink of nuclear war. Even though the story of Arkhipov preventing the launch of a nuclear torpedo wasn't declassified until decades after the incident, President John F. Kennedy reportedly estimated that he thought the odds of nuclear war beginning during that time were "somewhere between one out of three and even." This chilling admission highlights how the competitive pressures between militaries have the potential to cause global catastrophes.
**Individually rational decisions can be collectively catastrophic.** Nations locked in competition might make decisions that advance their own interests by putting the rest of the world at stake. Scenarios of this kind are collective action problems, where decisions may be rational on an individual level yet disastrous for the larger group [43]. For example, corporations and individuals may weigh their own profits and convenience over the negative impacts of the emissions they create, even if those emissions collectively result in climate change. The same principle can be extended to military strategy and defense systems. Military leaders might estimate, for instance, that increasing the autonomy of weapon systems would mean a 10 percent chance of losing control over weaponized superhuman AIs. Alternatively, they might estimate that using AIs to automate bioweapons research could lead to a 10 percent chance of leaking a deadly pathogen. Both of these scenarios could lead to catastrophe or even extinction. The leaders may, however, also calculate that refraining from these developments will mean a 99 percent chance of losing a war against an opponent. Since conflicts are often viewed as existential struggles by those fighting them, rational actors may accept an otherwise unthinkable 10 percent chance of human extinction over a 99 percent chance of losing a war. Regardless of the particular nature of the risks posed by advanced AIs, these dynamics could push us to the brink of global catastrophe.
**Technological superiority does not guarantee national security.** It is tempting to think that the best way of guarding against enemy attacks is to improve one's own military prowess. However, in the midst of competitive pressures, all parties will tend to advance their weaponry, such that no one gains much of an advantage, but all are left at greater risk. As Richard Danzig, former Secretary of the Navy, has observed, "On a number of occasions and in a number of ways, the American national security establishment will lose control of what it creates... deterrence is a strategy for reducing attacks, not accidents; it discourages malevolence, not inadvertence" [44].
**Cooperation is paramount to reducing risk.** As discussed above, an AI arms race can lead us down a hazardous path, despite this being in no country's best interest. It is important to remember that we are all on the same side when it comes to existential risks, and working together to prevent them is a collective necessity. A destructive AI arms race benefits nobody, so all actors would be rational to take steps to cooperate with one another to prevent the riskiest applications of militarized AIs.
We have considered how competitive pressures could lead to the increasing automation of conflict, even if decision-makers are aware of the existential threat that this path entails. We have also discussed cooperation as being the key to counteracting and overcoming this collective action problem. We will now illustrate a hypothetical path to disaster that could result from an AI arms race.
### Story: Automated Warfare
As AI systems become increasingly sophisticated, militaries start involving them in decision-making processes. Officials give them military intelligence about opponents' arms and strategies, for example, and ask them to calculate the most promising plan of action. It soon becomes apparent that AIs are reliably reaching better decisions than humans, so it seems sensible to give them more influence. At the same time, international tensions are rising, increasing the threat of war.
A new military technology has recently been developed that could make international attacks swifter and stealthier, giving targets less time to respond. Since military officials feel their response processes take too long, they fear that they could be vulnerable to a surprise attack capable of inflicting decisive damage before they would have any chance to retaliate. Since AIs can process information and make decisions much more quickly than humans, military leaders reluctantly hand them increasing amounts of retaliatory control, reasoning that failing to do so would leave them open to attack from adversaries.
While for years military leaders had stressed the importance of keeping a "human in the loop" for major decisions, human control is nonetheless gradually phased out in the interests of national security. Military leaders understand that their decisions lead to the possibility of inadvertent escalation caused by system malfunctions, and would prefer a world where all countries automated less; but they do not trust that their adversaries will refrain from automation. Over time, more and more of the chain of command is automated on all sides.
One day, a single system malfunctions, detecting an enemy attack when there is none. The system is empowered to launch an instant "retaliatory" attack, and it does so in the blink of an eye. The attack causes automated retaliation from the other side, and so on. Before long, the situation is spiraling out of control, with waves of automated attack and retaliation. Although humans have made mistakes leading to escalation in the past, this escalation between mostly-automated militaries happens far more quickly than any before. The humans who are responding to the situation find it difficult to diagnose the source of the problem, as the AI systems are not transparent. By the time they even realize how the conflict started, it is already over, with devastating consequences for both sides.
3.2 Corporate AI Race
---------------------
Competitive pressures exist in the economy, as well as in military settings. Although competition between companies can be beneficial, creating more useful products for consumers, there are also pitfalls. First, the benefits of economic activity may be unevenly distributed, incentivizing those who benefit most from it to disregard the harms to others. Second, under intense market competition, businesses tend to focus much more on short-term gains than on long-term outcomes. With this mindset, companies often pursue something that can make a lot of profit in the short term, even if it poses a societal risk in the long term. We will now discuss how corporate competitive pressures could play out with AIs and the potential negative impacts.
### 3.2.1 Economic Competition Undercuts Safety
**Competitive pressure is fueling a corporate AI race.** To obtain a competitive advantage, companies often race to offer the first products to a market rather than the safest. These dynamics are already playing a role in the rapid development of AI technology. At the launch of Microsoft's AI-powered search engine in February 2023, the company's CEO Satya Nadella said, "A race starts today... we're going to move fast." Only weeks later, the company's chatbot was shown to have threatened to harm users [45]. In an internal email, Sam Schillace, a technology executive at Microsoft, highlighted the urgency in which companies view AI development. He wrote that it would be an "absolutely fatal error in this moment to worry about things that can be fixed later" [46].
> “Nothing can be done at once hastily and prudently.” - *Publius Syrus*

**Competitive pressures have contributed to major commercial and industrial disasters.** In 1970, Ford Motor Company introduced the Ford Pinto, a new car model with a serious safety problem: the gas tank was located near the rear bumper. Safety tests showed that during a car crash, the fuel tank would often explode and set the car ablaze. Ford identified the problem and calculated that it would cost $11 per car to fix. They decided that this was too expensive and put the car on the market, resulting in numerous fatalities and injuries caused by fire when crashes inevitably happened [47]. Ford was sued and a jury found them liable for these deaths and injuries [48]. The verdict, of course, came too late for those who had already lost their lives. Ford's president at the time explained the decision, saying, "Safety doesn't sell" [49].
A more recent example of the dangers of competitive pressure is the case of the Boeing 737 Max aircraft. Boeing, aiming to compete with its rival Airbus, sought to deliver an updated, more fuel-efficient model to the market as quickly as possible. The head-to-head rivalry and time pressure led to the introduction of the Maneuvering Characteristics Augmentation System, which was designed to enhance the aircraft's stability. However, inadequate testing and pilot training ultimately resulted in the two fatal crashes only months apart, with 346 people killed [50]. We can imagine a future in which similar pressures lead companies to cut corners and release unsafe AI systems.
A third example is the Bhopal gas tragedy, which is widely considered to be the worst industrial disaster ever to have happened. In December 1984, a vast quantity of toxic gas leaked from a Union Carbide Corporation subsidiary plant manufacturing pesticides in Bhopal, India. Exposure to the gas killed thousands of people and injured up to half a million more. Investigations found that, in the run-up to the disaster, safety standards had fallen significantly, with the company cutting costs by neglecting equipment maintenance and staff training as profitability fell. This is often considered a consequence of competitive pressures [51].
**Competition incentivizes businesses to deploy potentially unsafe AI systems.** In an environment where businesses are rushing to develop and release products, those that follow rigorous safety procedures will be slower and risk being out-competed. Ethically-minded AI developers, who want to proceed more cautiously and slow down, would give more unscrupulous developers an advantage. In trying to survive commercially, even the companies that want to take more care are likely to be swept along by competitive pressures. There may be attempts to implement safety measures, but with more of an emphasis on capabilities than on safety, these may be insufficient. This could lead us to develop highly powerful AIs before we properly understand how to ensure they are safe.
### 3.2.2 Automated Economy
**Corporations will face pressure to replace humans with AIs.** As AIs become more capable, they will be able to perform an increasing variety of tasks more quickly, cheaply, and effectively than human workers. Companies will therefore stand to gain a competitive advantage from replacing their employees with AIs. Companies that choose not to adopt AIs would likely be out-competed, just as a clothing company using manual looms would be unable to keep up with those using industrial ones.
Figure 9: As AIs automate increasingly many tasks, the economy may become largely run by AIs. Eventually, this could lead to human enfeeblement and dependence on AIs for basic needs.**AIs could lead to mass unemployment.** Economists have long considered the possibility that machines will replace human labor. Nobel Prize winner Wassily Leontief said in 1952 that, as technology advances, "Labor will become less and less important... more and more workers will be replaced by machines" [52]. Previous technologies have augmented the productivity of human labor. AIs, however, could differ profoundly from previous innovations. Human-level AI would, by definition, be able to do everything a human could do. These AIs would also have important advantages over human labor. They could work 24 hours a day, be copied many times and run in parallel, and process information much more quickly than a human would. While we do not know when this will occur, it is unwise to discount the possibility that it could be soon. If human labor is replaced by AIs, mass unemployment could dramatically increase inequality, making individuals dependent on the owners of AI systems.
Advanced AIs capable of automating human labor should be regarded not merely as tools, but as agents. One particularly concerning aspect of AI agents is their potential to automate research and development across various fields, including biotechnology or even AI itself. This phenomenon is already occurring [53], and could lead to AI capabilities growing at increasing rates, to the point where humans are no longer the driving force behind AI development. If this trend continues unchecked, it could escalate risks associated with AIs progressing faster than our capacity to manage and regulate them, especially in areas like biotechnology where the malicious use of advancements could pose significant dangers. It is crucial that we strive to prevent undue acceleration of R&D and maintain a strong human-centric approach to technological development.
**Conceding power to AIs could lead to human enfeeblement.** Even if we ensure that the many unemployed humans are provided for, we may find ourselves completely reliant on AIs. This would likely emerge not from a violent coup by AIs, but from a gradual slide into dependence. As society's challenges become ever more complex and fast-paced, and as AIs become ever more intelligent and quick-thinking, we may forfeit more and more functions to them out of convenience. In such a state, the only feasible solution to the complexities and challenges compounded by AIs may be to rely even more heavily on AIs. This gradual process could eventually lead to the delegation of nearly all intellectual, and eventually physical, labor to AIs. In such a world, people might have few incentives to gain knowledge and cultivate skills, potentially leading to a state of enfeeblement. Having lost our know-how and our understanding of how civilization works, we would become completely dependent on AIs, a scenario not unlike the one depicted in the film WALL-E. In such a state, humanity is not flourishing and is no longer in effective control—an outcome that many people would consider a permanent catastrophe [54].
As we have seen, there are classic game-theoretic dilemmas where individuals and groups face incentives that are incompatible with what would make everyone better off. We see this with a military AI arms race, where the world is made less safe by creating extremely powerful AI weapons, and we see this in a corporate AI race, where an AI's power and development is prioritized over its safety. To address these dilemmas that give rise to global risks, we will need new coordination mechanisms and institutions. It is our view that failing to coordinate and stop AI races would be the most likely cause of an existential catastrophe.
3.3 Evolution
-------------
As discussed above, there are strong pressures to replace humans with AIs, cede more control to them, and reduce human oversight in various settings, despite the potential harms. We can re-frame this as a general trend resulting from evolutionary dynamics, where an unfortunate truth is that AIs will simply be more fit than humans. Extrapolating this pattern of automation, it is likely that we will build an ecosystem of competing AIs over which it may be difficult to maintain control in the long run. We will now discuss how natural selection influences the development of AI systems and why evolution favors selfish behaviors. We will also look at how competition might arise and play out between AIs and humans, and how this could create catastrophic risks. This section draws heavily from "*Natural Selection Favors AIs over Humans*" [55, 56].
**Fitter technologies are selected, for good and bad.** While most people think of evolution by natural selection as a biological process, its principles shape much more. According to the evolutionary biologist Richard Lewontin [57], evolution by natural selection will take hold in any environment where three conditions are present: 1) there are differences between individuals; 2) characteristics are passed onto future generations and; 3) the different variants propagate at different rates. These conditions apply to various technologies.
Consider the content-recommendation algorithms used by streaming services and social media platforms. When a particularly addictive content format or algorithm hooks users, it results in higher screen time and engagement. This more effective content format or algorithm is consequently "selected" and further fine-tuned, while formats and algorithms that fail to capture attention are discontinued. These competitive pressures foster a "survival of the most addictive" dynamic. Platforms that refuse to use addictive formats and algorithms become less influential or are simply outcompeted by platforms that do, leading competitors to undermine wellbeing and cause massive harm to society [58].
Figure 10: Evolutionary pressures are responsible for various developments over time, and are not limited to the realm of biology.**The conditions for natural selection apply to AIs.** There will be many different AI systems with varying features and capabilities, and competition between them will determine which characteristics become more common. The most successful AIs today are already being used as a basis for their developers' next generation of models, as well as being imitated by rival companies. Factors determining which AIs propagate the most may include their ability to act autonomously, automate labor, or reduce the chance of their own deactivation.
**Natural selection often favors selfish characteristics.** Natural selection influences which AIs propagate most widely. From biological systems, we see that natural selection often gives rise to selfish behaviors that promote one's own genetic information: chimps attack other communities [59], lions engage in infanticide [60], viruses evolve new surface proteins to deceive and bypass defense barriers [61], humans engage in nepotism, some ants enslave others [62], and so on. In the natural world, selfishness often emerges as a dominant strategy; those that prioritize themselves and those similar to them are usually more likely to survive, so these traits become more prevalent. Amoral competition can select for traits that we think are immoral.
**Selfish behaviors may not be malicious or even intentional.** Species in the natural world do not evolve selfish traits deliberately or consciously. Selfish traits emerge as a product of competitive pressures. Similarly, AIs do not have to be malicious to act selfishly—instead, they would evolve selfish traits as an adaptation to their environment. AIs might engage in selfish behavior—expanding their influence at the expense of humans—simply by automating human jobs. AIs do not intend to displace humans. Rather, the environment in which they are being developed, namely corporate AI labs, is pressuring AI researchers to select for AIs that automate and displace humans. Another example of unintentional selfish behavior is when AIs assume roles humans depend on. AIs may eventually become enmeshed in vital infrastructure such as power grids or the internet. Many people may then be unwilling to accept the cost of being able to effortlessly deactivate them, as that would pose a reliability hazard. Similarly, AI companions may induce people to become emotionally dependent on them. Some of those people may even begin to argue that their AI companions should have rights. If some AIs are given rights, they may operate, adapt, and evolve outside of human control. AIs could become embedded in human society and expand their influence over us in ways that we can't easily reverse.
**Selfish behaviors may erode safety measures that some of us implement.** AIs that gain influence and provide economic value will predominate, while AIs that adhere to the most constraints will be less competitive. For example, AIs following the constraint "never break the law" have fewer options than AIs following the constraint "don't get caught breaking the law." AIs of the latter type may be willing to break the law if they're unlikely to be caught or if the fines are not severe enough, allowing them to outcompete more restricted AIs. Many businesses follow laws, but in situations where stealing trade secrets or deceiving regulators is highly lucrative and difficult to detect, a business that is willing to engage in such selfish behavior can have an advantage over its more principled competitors.
An AI system might be prized for its ability to achieve ambitious goals autonomously. It might, however, be achieving its goals efficiently without abiding by ethical restrictions, while deceiving humans about its methods. Even if we try to put safety measures in place, a deceptive AI would be very difficult to counteract if it is cleverer than us. AIs that can bypass our safety measures without detection may be the most successful at accomplishing the tasks we give them, and therefore become widespread. These processes could culminate in a world where many aspects of major companies and infrastructure are controlled by powerful AIs with selfish traits, including deceiving humans, harming humans in service of their goals, and preventing themselves from being deactivated.
**Humans only have nominal influence over AI selection.** One might think we could avoid the development of selfish behaviors by ensuring we do not select AIs that exhibit them. However, the companies developing AIs are not selecting the safest path but instead succumbing to evolutionary pressures. One example is OpenAI, which was founded as a nonprofit in 2015 to "benefit humanity as a whole, unconstrained by a need to generate financial return" [63]. However, when faced with the need to raise capital to keep up with better-funded rivals, in 2019 OpenAI transitioned from a nonprofit to “capped-profit” structure [64]. Later, many of the safety-focused OpenAI employees left and formed a competitor, Anthropic, that was to focus more heavily on AI safety than OpenAI had. Although Anthropic originally focused on safety research, they eventually became convinced
of the "necessity of commercialization" and now contribute to competitive pressures [65]. While many of the employees at those companies genuinely care about safety, these values do not stand a chance against evolutionary pressures, which compel companies to move ever more hastily and seek ever more influence, lest the company perish. Moreover, AI developers are already selecting AIs with increasingly selfish traits. They are selecting AIs to automate and displace humans, make humans highly dependent on AIs, and make humans more and more obsolete. By their own admission, future versions of these AIs may lead to extinction [66]. This is why an AI race is insidious: AI development is not being aligned with human values but rather with evolution.
People often choose the products that are most useful and convenient to them immediately, rather than thinking about potential long-term consequences, even to themselves. An AI race puts pressures on companies to select the AIs that are most competitive, not the least selfish. Even if it's feasible to select for unselfish AIs, if it comes at a clear cost to competitiveness, some competitors will select the selfish AIs. Furthermore, as we have mentioned, if AIs develop strategic awareness, they may counteract our attempts to select against them. Moreover, as AIs increasingly automate various processes, AIs will affect the competitiveness of other AIs, not just humans. AIs will interact and compete with each other, and some will be put in charge of the development of other AIs at some point. Giving AIs influence over which other AIs should be propagated and how they should be modified would represent another step toward human becoming dependent on AIs and AI evolution becoming increasingly independent from humans. As this continues, the complex process governing AI evolution will become further unmoored from human interests.
**AIs can be more fit than humans.** Our unmatched intelligence has granted us power over the natural world. It has enabled us to land on the moon, harness nuclear energy, and reshape landscapes at our will. It has also given us power over other species. Although a single unarmed human competing against a tiger or gorilla has no chance of winning, the collective fate of these animals is entirely in our hands. Our cognitive abilities have proven so advantageous that, if we chose to, we could cause them to go extinct in a matter of weeks. Intelligence was a key factor that led to our dominance, but we are currently standing on the precipice of creating entities far more intelligent than ourselves.
Given the exponential increase in microprocessor speeds, AIs have the potential to process information and "think" at a pace that far surpasses human neurons, but it could be even more dramatic than the speed difference between humans and sloths. They can assimilate vast quantities of data from numerous sources simultaneously, with near-perfect retention and understanding. They do not need to sleep and they do not get bored. Due to the scalability of computational resources, an AI could interact and cooperate with an unlimited number of other AIs, potentially creating a collective intelligence that would far outstrip human collaborations. AIs could also deliberately update and improve themselves. Without the same biological restrictions as humans, they could adapt and therefore evolve unspeakably quickly compared with us. AIs could become like an invasive species, with the potential to out-compete humans. Our only advantage over AIs is that we get to get make the first moves, but given the frenzied AI race we are rapidly giving up even this advantage.
**AIs would have little reason to cooperate with or be altruistic toward humans.** Cooperation and altruism evolved because they increase fitness. There are numerous reasons why humans cooperate with other humans, like direct reciprocity. Also known as "quid pro quo," direct reciprocity can be summed up by the idiom "you scratch my back, I'll scratch yours." While humans would initially select AIs that were cooperative, the natural selection process would eventually go beyond our control, once AIs were in charge of many or most processes, and interacting predominantly with one another. At that point, there would be little we could offer AIs, given that they will be able to "think" at least hundreds of times faster than us. Involving us in any cooperation or decision-making processes would simply slow them down, giving them no more reason to cooperate with us than we do with gorillas. It might be difficult to imagine a scenario like this or to believe we would ever let it happen. Yet it may not require any conscious decision, instead arising as we allow ourselves to gradually drift into this state without realizing that human-AI co-evolution may not turn out well for humans.
**AIs becoming more powerful than humans could leave us highly vulnerable.** As the most dominant species, humans have deliberately harmed many other species, and helped drive species such as Neanderthals to extinction. In many cases, the harm was not even deliberate, but instead a result of us merely prioritizing our goals over their wellbeing. To harm humans, AIs wouldn't need to be any more genocidal than someone removing an ant colony on their front lawn. If AIs are able to control the environment more effectively than we can, they could treat us with the same disregard.
**Conceptual summary.** Evolutionary forces could cause the most influential future AI agents to have selfish tendencies. That is because:
1. **Evolution by natural selection gives rise to selfish behavior.** While evolution can result in altruistic behavior in rare situations, the context of AI development does not promote altruistic behavior.
2. **Natural selection may be a dominant force in AI development.** The intensity of evolutionary pressure will be high if AIs adapt rapidly or if competitive pressures are intense. Competition and selfish behaviors may dampen the effects of human safety measures, leaving the surviving AI designs to be selected naturally.
If so, AI agents would have many selfish tendencies. The winner of the AI race would not be a nation-state, not a corporation, but AIs themselves. The upshot is that the AI ecosystem would eventually stop evolving on human terms, and we would become a displaced, second-class species.
### Story: Autonomous Economy
As AIs become more capable, people realize that we could work more efficiently by delegating some simple tasks to them, like drafting emails. Over time, people notice that the AIs are doing these tasks more quickly and effectively than any human could, so it is convenient to give them more jobs with less and less supervision.
Competitive pressures accelerate the expansion of AI use, as companies can gain an advantage over rivals by automating whole processes or departments with AIs, which perform better than humans and cost less to employ. Other companies, faced with the prospect of being out-competed, feel compelled to follow suit just to keep up. At this point, natural selection is already at work among AIs; humans choose to make more of the best-performing models and unwittingly propagate selfish traits such as deception and self-preservation if these confer a fitness advantage. For example, AIs that are charming and foster personal relationships with humans become widely copied and harder to remove.
As AIs are put in charge of more and more decisions, they are increasingly interacting with one another. Since they can evaluate information much more quickly than humans, activity in most spheres accelerates. This creates a feedback loop: since business and economic developments are too fast-moving for humans to follow, it makes sense to cede yet more control to AIs instead, pushing humans further out of important processes. Ultimately, this leads to a fully autonomous economy, governed by an increasingly uncontrolled ecosystem of AIs.
At this point, humans have few incentives to gain any skills or knowledge, because almost everything would be taken care of by much more capable AIs. As a result, we eventually lose the capacity to look after and govern ourselves. Additionally, AIs become convenient companions, offering social interaction without requiring the reciprocity or compromise necessary in human relationships. Humans interact less and less with one another over time, losing vital social skills and the ability to cooperate. People become so dependent on AIs that it would be intractable to reverse this process. What's more, as some AIs become more intelligent, some people are convinced these AIs should be given rights, meaning turning off some AIs is no longer a viable option.
Competitive pressures between the many interacting AIs continue to select for selfish behaviors, though we might be oblivious to this happening, as we have already acquiesced much of our oversight. If these clever, powerful, self-preserving AIs were then to start acting in harmful ways, it would be all but impossible to deactivate them or regain control.
AIs have supplanted humans as the most dominant species and their continued evolution is far beyond our influence. Their selfish traits eventually lead them to pursue their goals without regard for human wellbeing, with catastrophic consequences.
Suggestions
-----------
Mitigating the risks from competitive pressures will require a multifaceted approach, including regulations, limiting access to powerful AI systems, and multilateral cooperation between stakeholders at both the corporate and nation-state level. We will now outline some strategies for promoting safety and reducing race dynamics.
**Safety regulation.** Regulation holds AI developers to a common standard so that they do not cut corners on safety. While regulation does not itself create technical solutions, it can create strong incentives to develop and implement those solutions. If companies cannot sell their products without certain safety measures, they will be more willing to develop those measures, especially if other companies are also held to the same standards. Even if some companies voluntarily self-regulate, government regulation can help prevent less scrupulous actors from cutting corners on safety. Regulation must be proactive, not reactive. A common saying is that aviation regulations are "written in blood"—but regulators should develop regulations before a catastrophe, not afterward. Regulations should be structured so that they only create competitive advantages for companies with higher safety standards, rather than companies with more resources and better attorneys. Regulators should be independently staffed and not dependent on any one source of expertise (for example, large companies), so that they can focus on their mission to regulate for the public good without undue influence.
**Data documentation.** To ensure transparency and accountability in AI systems, companies should be required to justify and report the sources of data used in model training and deployment. Decisions by companies to use datasets that include hateful content or personal data contribute to the frenzied pace of AI development and undermine accountability. Documentation should include details regarding the motivation, composition, collection process, uses, and maintenance of each dataset [67].
**Meaningful human oversight of AI decisions.** While AI systems may grow capable of assisting human beings in making important decisions, AI decision-making should not be made fully autonomous, as the inner workings of AIs are inscrutable, and while they can often give *reasonable* results, they fail to give highly *reliable* results [68]. It is crucial that actors are vigilant to coordinate on maintaining these standards in the face of future competitive pressures. By keeping humans in the loop on key decisions, irreversible decisions can be double-checked and foreseeable errors can be avoided. One setting of particular concern is nuclear command and control. Nuclear-armed countries should continue to clarify domestically and internationally that the decision to launch a nuclear weapon must always be made by a human.
**AI for cyberdefense.** Risks resulting from AI-powered cyberwarfare would be reduced if cyberattacks became less likely to succeed. Deep learning can be used to improve cyberdefense and reduce the impact and success rate of cyberattacks. For example, improved anomaly detection could help detect intruders, malicious programs, or abnormal software behavior [69].
**International coordination.** International coordination can encourage different nations to uphold high safety standards with less worry that other nations will undercut them. Coordination could be accomplished via informal agreements, international standards, or international treaties regarding the development, use, and monitoring of AI technologies. The most effective agreements would be paired with robust verification and enforcement mechanisms.
**Public control of general-purpose AIs.** The development of AI poses risks that may never be adequately accounted for by private actors. In order to ensure that externalities are properly accounted for, direct public control of general-purpose AI systems may eventually be necessary. For example, nations could collaborate on a single effort to develop advanced AIs and ensure their safety, similar to how CERN serves as a unified effort for researching particle physics. Such an effort would reduce the risk of nations spurring an AI arms race.
Positive Vision:
----------------
In an ideal scenario, AIs would be developed, tested, and subsequently deployed only when the catastrophic risks they pose are negligible and well-controlled. There would be years of time testing, monitoring, and societal integration of new AI systems before beginning work on the next generation. Experts would have a full awareness and understanding of developments in the field, rather than being entirely unable to keep up with a deluge of research. The pace of research advancement would be determined through careful analysis, not frenzied competition. All AI developers would be confident in the responsibility and safety of the others and not feel the need to cut corners.

Misha and I recently recorded a short discussion about large language models and their uses for effective altruists.
This was mostly a regular Zoom meeting, but we added some editing and text transcription. After we wrote up the transcript, both Misha and myself edited our respective sections.
I think the final transcript is clearer and contains more information than the original discussion. I might even suggest using text-to-speech on the transcript rather than listening to the original audio. This back-and-forth might seem to ruin the point of presenting the video and audio, but I think it might be straightforwardly more pragmatic.

### Opening
**Ozzie:** Hello. I just did a recording with my friend Misha, an EA researcher at [ARB Research](https://arbresearch.com/). This was a pretty short meeting about large language models and their use by effective altruists. The two of us are pretty excited about the potential for large language models to be used by effective altruists for different kinds of infrastructure.
This is an experiment with us presenting videos publicly. Normally, our videos are just Zoom meetings. If anything, the Zoom meetings would be unedited. I found that to be quite a pain. These Zoom meetings typically don't look that great on their own, and they don't sound too terrific. So we've been experimenting with some methods to try to make that a little bit better.
I am really curious about what people are going to think about this and am looking forward to what you say. Let's get right into it.
### Introduction
**Ozzie:** For those watching us, this is Misha and me just having a meeting about large language models and their use for effective altruism.
Obviously, large language models have been a very big deal very recently, and now there's a big question about how we could best apply them to EA purposes and what EAs could do best about it. So this is going to be a very quick meeting. We only have about half an hour.
Right now, we have about seven topics. The main topic, though, is just the LLM applications.
### How do we use LLMs already?
**Ozzie:** So, how do we use LLMs already?
**Misha:** I think I use them for roughly 10 minutes on average per day.
Sometimes I just ask questions or ask queries like, "Hey, I have these ingredients. What cocktails can I make?" Sometimes I try to converse with them about stuff. Sometimes I just use it (e.g., text-davinci-003) as a source of knowledge. I think it's more suitable for areas where verifiable expertise is rare.
Take non-critical medicine, like skincare. I had a chat with it and got some recommendations in this domain, and I think it turned out really well. I previously tried to search for recommendations and asked a few people, but it didn't work.
I also use it as an amplification for journaling whenever I'm doing any emotional or self-coaching work. Writing is great. I personally find it much easier to write “as if” I'm writing a message to someone—having ChatGPT obviously helps with that.
Having a conversation partner activates some sort of social infrastructure in my brain. Humans solve math problems better when they are framed socially. And yeah, doing it with language models is straightforward and really good. Further, sometimes models give you hints or insights that you forgot to think about.
You can ask tons of questions and be really annoying, which you might not be comfortable doing with your friend or even with a professional. One trick I used previously to prompt a human medical professional to give me some sort of cost-benefit analysis was to ask them: "Well, if instead of me, you were giving an advice to your son or daughter, what would you do?" This makes them actually think. With LLMs, you can probe straightforwardly and see where their limits are.
Ozzie, what about you?
**Ozzie:** Yeah, I have used it in a few cases, particularly to rewrite Facebook posts. Both to clean them up, also to try to change them into Tweets. This had some success. I think rewriting in different styles is quite nice. I've been experimenting with a lot of semi-EA purposes.
So some of it is like taking very aggressive writing and rewriting it for the EA Forum. And then, ChatGPT knows that writing for the EA Forum means making it super polite and long.
I'm having trouble getting it to come up with cool metaphors and witty, historic examples. There are a few cases where I tried coming up with a list of 10 examples of this intellectual idea, like negative externalities from this historical era.
Like, from 400 BC to like, 680 BC or something; in some cases it works and in some cases, it doesn't. It feels like hypothetically you should be able to come up with a Scott Alexander post-type content. Just come up with 10 good historical examples on an idea and write cool anecdotes.
Also, of course, trying to come up with whole Seinfeld episodes about any topic of your choice or something like that is starting to be possible.
I tried using it a bit for evaluating information, so I'd say, come up with like 10 attributes to rate this intellectual, and then in each one, judge the intellectual. And it did.
It definitely is gonna require some work, but it's able to kind of start, it could at least differentiate that Donald Trump gets very low marks as an intellectual. In comparison, most of the intellectuals, I could come up with had very high marks.
### Could EAs contributing to applied LLMs be harmful?
**Ozzie:** Next topic. Can this do more harm than good?
So, there's one camp that may be extreme that would say any use of AI would be advancing AI in the same capability, and that'll be like net bad.
But that said, A, this is a long argument and discussion. So we want to get more into applications, and we don't want to spend much time on that. But B, my guess is that a lot of people would agree that there are probably just some pretty cheap wins that we could take, without extending the theory of language models or the total capabilities of language models, but still getting some valuable things with them. Some decent risk-reward trade-offs.
**Misha:** I basically agree.
I think interfaces are one area that currently sucks. Making better interfaces can help everyone think a bit better, especially with later models. I'm not sure if this would substantially accelerate capabilities.
**Ozzie:** In terms of groups that we don't want to have developed better epistemic, there are definitely some authoritarian regimes that would be bad. The next one that could be problematic is AI-development organizations.
If EA helps develop tools that help people have better epistemic or rational reasoning, maybe they'll be used to make AIs faster. Again, I don't know how big of a deal this is, but I think that may be one of the main things to be thinking about.
**Misha:** I basically expect AI labs to start squeezing out these models to improve productivity. Though I think most of it, for now, will be via Codex-like tech, e.g., doing sysadmin better. People made ChatGPT simulate a terminal, which is suggestive.
### Application: Management and Emotional Assistance
**Ozzie:** So how about we get into applications? That's the main topic. You have a few applications to discuss, and then I have a few applications. What are your favorite applications?
**Misha:** To just continue the discussion about differential progress. People in EA think that independent researchers and other loners struggle without proper management.
I think a bunch of helpful things in this direction can be achieved via GPT. So I wouldn't be surprised if someone figured out how to turn models into research managers to help with performance coaching and other things. This seems positive.
Another one: there is a lot of untapped knowledge on Reddit and in other amazing communities. They don’t do proper science, but by just trying to figure out what actually works, they collect useful insight. And you can pull it out of LLMs by asking to be a knowledgeable member of such a community.
Likewise, you can get perspective through the eyes of others. GPT is sort of a phenomenological museum—you know, a window into other worlds.
I really like [Clearer Thinking](https://www.clearerthinking.org/). They have programs to improve people's mental tools. If you're taking their quiz, it's very nice in isolation, but it’d be cooler if you were able to do them alongside LLM to be able to chat about ideas and analyze results. The conversation is better than a linear progression. "Oh, I am inconsistent in how I value my time. Why don’t I feel comfortable spending money to buy time?” is an excellent moment to reflect more, and GPT might be good at holding space for it.
Lastly, I think Scott Alexander wrote about a hypothetical client who was upset with his partner, claiming they didn’t really love them. The problem was that they wanted to have a hot cooked dinner every night they come from work. But their partner works, so it wasn't possible every time. Scott just suggested calling your partner in advance and, if they would be able to come home early enough to cook dinner, just... order Uber Eats. It worked! I think a bunch of human problems are debuggable and are often simple.
**Ozzie:** How would that work: of GPT understanding a human's life well enough to know what to recommend and what you need? Would it need some information about what you're doing?
**Misha:** Right.
And in this case, an emotionally responsive model can simply ask, "What's up?" "Why are you thinking that?" "How would that make you feel?" Someone is creating a safe space for people to think. Because unless you—I dunno—unless I'm writing, I just can't really pull it all together and make a connection. Google Docs is amazing for that. Making it more conversational, I believe, would make it easier for more people.
**Ozzie:** Hypothetically, it seems like people are going to be trying to import people's emails and social media posts and stuff like that to just begin with a lot of information about the person, and then from that they could hypothetically make a lot of recommendations.
In the interest of time, let's go to the next topic.
### Application: Communication, Broadly
**Ozzie:** The first application I have to discuss is communication in general. I wrote [one post](https://www.lesswrong.com/posts/PC4yowA2TiRne69iD/expansive-translations-considerations-and-possibilities) about this. Arguably, translating English to Russian is similar to translating English spoken by a ninth grader in Detroit into a language spoken by someone very different, using different terminology and cultural markers.
People want to be communicated with very personally, so having something that understands them very well, knows what they know, and could explain things in terms that they understand just gives you a massive benefit, hypothetically.
I think in EA there's definitely a whole lot in the philosophical literature that we just don't know and that no one so far has figured out. Hypothetically GPT could understand all of that and say "oh, these 10 insights are the most valuable." Right now, instead, these fields are all like coded with continental philosophical language or coded with other terminology that we're really not used to, or like these other foundation assumptions that we don’t understand or agree with.
What a lot of people want is a personal tutor that understands it very well and understands how they learn. So we kind of want things like chatbots to become personalized tutors in any individualized style of communication. So hypothetically that's just like a whole lot of value on the table.
**Misha:** An example would be asking Model to summarize key insights of postmodernism for someone who is libertarian-ish or reads LessWrong. This will probably work quite well.
Likewise, you can communicate in your own language. Well, the doctor doesn’t get my math metaphors or someone else’s cooking metaphors. Contrary to GPT, which speaks both math and cooking fluently and can understand them.
Say you want to use "simulated annealing" as a metaphor for how you approach one area of your life. LLM would understand you, while friends might not. Shorter inferential differences mean less need to explain yourself or build toward a thesis—you can just shoot.
**Ozzie:** I guess one analogy is [TV tropes](https://tvtropes.org/). It has great lists of many super-specific things. Like, for many very specific tropes that exist online, here's every single example of it in every type of media.
That's very different from Wikipedia. There are a lot of intellectual terminologies that are not connected at all. So it is pretty common for me to find that, oh, this interesting term was actually cited in like 10 different manuscripts or something like that and used in these different ways.
But you should know that each way it's used is slightly different. So it's just like a huge pain that, hypothetically, could be solved. I guess going down a bit and finding mistakes and miscommunications would be great. I think people very often misunderstand stuff online, at least when I'm writing comments to people. I'm constantly misunderstanding people when I try to respond and stuff.
Hypothetically, there could be a browser extension that flags bad text in red and says "Oh, these few words you're probably going to misunderstand." And then if you hover over it, you can see what it actually means. Of course, that's not as intense as something that rewrites all the content for you in ways that it's pretty sure you're going to understand, which is probably more what you'd like.
**Misha:** Right.
I think you probably thought about having this conversation not between me and you but between you, your AI, my AI, and me. It might smooth things a lot by interacting between different cultures.
**Ozzie:** Yeah.
### Human-AI-Human Communication
**Ozzie:** I think that human-to-human conversation is just really mediocre.
Humans are simply not very good at communicating with one another. It's very complicated. You have to understand where the other person's coming from; we have many different types of humans with different backgrounds. And then *you* also have to understand *them*. Both of those challenges are dramatically more complicated than people give them credit for.
So I think we want to move to this human-AI-human model, where AI is figuring out how to extract valuable information from humans, which probably looks a lot different than them writing essays or anything like that. I have no idea what the ideal is going to be. Perhaps the AI just asks people very targeted questions.
And then, very separately, the AI develops an embedding of the important information that comes from humans and communicates information that could partially come from that to other humans as it's most needed.
The way to write an essay in the future, for a human, would be not to write an essay but instead to get interrogated by a language model.
In another world, we would actually just stop with the idea of essays. Instead, you get like four intellectual credits, because that's about how much interesting information you've contributed to the AI system. And then, when people want information, they just get whatever ideas they want. Content comes from a mess of different people and stuff, and that's totally fine.
Miscommunication is huge. If you could completely eliminate miscommunication online, I think that would be worth a lot of money. I think therapists, like marriage therapists, do a lot of trying to get communication to be decent. So if an AI could do that for you, that would be huge.
**Misha:** Right.
### Application: Decision Automation
**Misha:** Also, like a lot of small businesses, some are dysfunctional. The Profit, a TV show, shows how a lot of them are disasters. Sure, there are some selection effects. But a lot of it is due to poor emotional and conversational skills. Well, also poor basic business skills.
**Ozzie:** Now, there’s a super interesting question, which is, *“How much decision-making can we automate pretty easily with a combination of language models and a few other tools”*? Like hypothetically, a lot of business decisions are just not being made that well. A lot of bureaucratic decisions are probably worse than a decent guess by a properly trained agent or something.
It's not super clear exactly when we'll reach what thresholds. But yeah, there are a lot of bad decisions being made.
**Misha:** Right. I think it would be like really hard to secure agreement from the involved actors. People don’t like when others override their decisions, and they wouldn’t like LLMs to do it either. I think this is one of the problems with the adoption of prediction markets in corporations.
**Ozzie:** I think one good model is that of autonomous vehicles.
It’s level one before you get to level five. Levels one and two are just like driver assist. And then, as the systems get better, people will rely on them more.
**Misha:** Slower adaptation is good. Initially just ask good probing questions in a non-threatening manner, and you're like, "*oh yeah, that's a good point. I'll, I will do that*". And because no one told you to do that, whether it was some AI from OpenAI or another company, you don't even lose social standing. You don’t look weak or anything. So even a very bossy person can agree.
As a side note, I think the same dynamic might enable men to do more therapy-shaped things via LLMs.
**Ozzie:** I imagine, too, that these AI models would be very useful in the sense that they'd be deemed much less biased than a lot of the bosses and other people making the decisions.
If someone's in charge of a big government contract and wants to make a big decision about it, that might be suspect. There are a lot of opportunities for bias.
If they had an AI kind of say, "*oh yeah, that's what I would do, too*", that would give them a fair bit more credibility. So just having some assistance could be useful.
There are also definitely some situations where I expect people to only trust AI because, like, they just can't trust any responsible person to make a decent decision.
### Application: EA Forum Improvements
**Ozzie:** There are a bunch of potential uses of GPT for the EA Forum.
First, there are a lot of new users who really take time to get used to the community norms. They come in pretty grumpy, or they don't know what terminology we use. EA does have pretty unusual epistemic standards that are difficult to teach.
In theory, when you're writing a post, you should be able to see in real-time what the comments will be and what the karma for that post will be. So as you're editing, you write a bad sentence and immediately see an imagined angry comment. And then you say, "Okay, I guess I'll just delete that sentence." Obviously, this assistant service does have some harm as well as benefits, but hypothetically, some of the angry comments that we see could just be seen in advance and then prevented.
You could also have less intense steps, such as "Oh, your writing style probably isn't up to the best standards and probably won't be properly appreciated, but here's our version of rewriting it, that you're free to take inspiration from."
In terms of people reading articles on the EA Forum, we may just have 10 different versions of an article or something. Writers give it a few sliders of, "Oh, do I want the very summarized version? Do I want the, like, very long version? Do I want it to use stories from what historical period or something similar?” And the articles could be automatically adjusted accordingly.
### Application: Evaluations
**Ozzie:** I see evaluation is a really major application for LLMs. In this case, it just means that for every EA Forum post or comment, we have an estimate of how well-written this is and how likely this is to hold up after scrutiny. How inflammatory does it seem? How good or bad does this post seem on a few different spectrums?
Hypothetically, we could have a lot of these auto-evaluations done. That's just on the EA Forum, of course. We'd really want that in all of Twitter and all of the media. Of course, it's debatable what those would look like.
**Misha:** Yeah. Unbelievable today this is in the realm of possible, while some years ago sentiment prediction was mediocre or so.
**Ozzie:** A whole lot of things are possible all of a sudden. It's like a really freaking interesting time.
### **LLM UXs**
**Ozzie:** So, moving on, um, UX issues. What do you think about UX issues?
**Misha:** Oh yeah. You basically have two interfaces. One is Chat GPT, where, like your model, it is very polite and restricted, which is not ideal, but the chat interface is nice. Another one is to just continue the line, text completion, where you can, of course, recreate the chat model and other things.
But this all seems not that exciting because the second one is just LLM default, predicting the next token. Chat mode is nice and more humane and hence appreciated. But also, it’s the first idea you would have. I think Janus builds what they call "multiverses," where you just branch text in all sorts of directions, give only a few prompts, and rely mostly on curation. This is really nice. This is another interface that is available.
Today's appreciation and perception of capabilities are probably limited by the fact that you just get one thing as a response and can't easily customize how it's generated.
The next thing would be to have conversations with multiple LLM-simulated partners, which would have different characters, different perspectives, and so on. You’d be able to have a wide array of shoulder advisors. Someone who is more direct would be straightforward; someone else would be more nuanced and careful; someone would ask, “All these considerations are good, but what do you want?”; another would be appreciative and emotionally soothing or something.
I hope for more interfaces. But in practice, humans are kind of bad at developing new ones. It's like we still owe everything to Xerox PARK, right? But interfaces might unlock new creative ways to make models useful and helpful. But it took us a while to figure out that you need to ask them to “think step by step.” So probably exciting new crazy interfaces are not coming anytime soon.
**Ozzie:** I think my quick take is that, um, on the internet, it probably took thousands of UX and design years to figure out what websites should look like.
And then, once we had mobile devices, it took many hundreds or thousands of years to figure out what that should look like. It's just a huge amount of work to really figure out the UX and UI for a new medium. And this appears to be more distinct to me than regular Web versus mobile. It seems like a much bigger shift, so I'd expect it to take a lot of time.
### What should EAs do with LLMs?
**Ozzie:** So yeah, in the very end, um, what should EA do now?
**Misha:** It's unclear if, like, EAs are anything special. I sincerely hope that people outside of the alignment community will pay more attention to this new technology, adopt these language models, and use it for their own benefit.
But yes, as previously mentioned, figuring out how to do research management well with LLMs might be very helpful. I would be pretty excited if someone spent a month or more intensely trying to integrate LLMs into their processes and workflows.
Oh, yeah, I am a bit involved in collecting all sorts of helpful base rates. For forecasting purposes and just to inform people about them. I previously figured out I can just ask ChatGPT to give me more examples of events I am interested in, like “what are huge secret projects that have remained secret for a long time?” And of course, I got a list of 30+ and never heard about most of them.
**Ozzie:** Yeah, that makes sense. It is also a big topic. But we need to finish up now. Thanks so much for your time. Any last comments?
**Misha:** Nope. Thanks for hosting, Ozzie.
**Ozzie:** Yeah. Thank you. |
fa399c93-eca4-426e-a0fa-e52908081b53 | StampyAI/alignment-research-dataset/aisafety.info | AI Safety Info | How is the Alignment Research Center (ARC) trying to solve Eliciting Latent Knowledge (ELK)?
[ARC](https://www.alignment.org/) is trying to solve the problem of [Eliciting Latent Knowledge (ELK)](https://docs.google.com/document/d/1WwsnJQstPq91_Yh-Ch2XRL8H_EpsnjrC1dwZXR37PC8/edit). Suppose that you are training a *predictor—*an AI agent that predicts the state of the world and then performs some actions. How can you create another model—a *reporter*—that tells you what the predictor believes about the world? A key challenge is that training your reporter on human-labeled training data incentivizes the predictor to model what the human trainer would believe is true, because modeling "what the human would believe to be true" will receive human approval *more consistently* than the actual truth, since the human may sometimes be mistaken!
Paul Christiano's plan seems to be to produce a minimal AI that can help to do AI safety research. To do this, preventing [deception](https://www.alignmentforum.org/posts/ocWqg2Pf2br4jMmKA/does-sgd-produce-deceptive-alignment) and [inner alignment failure](https://www.alignmentforum.org/posts/pL56xPoniLvtMDQ4J/the-inner-alignment-problem) are on the critical path, and the only known solutions require interpretability (this is how all of Evan Hubinger's [11 proposals](https://www.alignmentforum.org/posts/fRsjBseRuvRhMPPE5/an-overview-of-11-proposals-for-building-safe-advanced-ai) plan to get around this problem).
If ARC can solve ELK, this would be a very strong form of interpretability: our reporter is able to tell us what the predictor believes about the world. Some ways this could be useful for aligning the predictor include:
- Using the reporter to find deceptive/misaligned thoughts in the predictor, and then optimizing against those interpreted thoughts. At any time, stochastic gradient descent only updates the weights a small amount. If an AI becomes misaligned, it won't be very misaligned, and the interpretability tools will be able to discover this and do a gradient step to realign it. In this way, we can prevent deception at any point in training.
- Stopping training if the AI is misaligned.

All bold claims and ignorant mistakes herein are my own.
Do you remember when Evan Hubinger became really enamored with 'training stories,' a way of carving up the alignment problem into 'training rationales' and 'training goals'? Evan's idea was that we ought to think of alignment as choosing a target model that we want to end up with after training, plus choosing a training procedure that will actually yield that model. In my prior experience talking to people about this way of framing the alignment problem… people didn't especially get it. The typical response of those who had heard of this was, "Yeah, that's one way to carve up the problem apart from, e.g., inner and outer alignment. But so what? How does this framing help us actually reduce the problem? It seems no better or worse than our old framings."
I used to have that response myself. However, I now think I understand training stories! Here's my take:
What Do Training Stories Buy You That Inner/Outer Alignment Doesn't?
> It’s worth pointing out how phrasing inner and outer alignment in terms of training stories makes clear what I think was our biggest mistake in formulating that terminology, which is that inner/outer alignment presumes that the right way to build an aligned model is to find an aligned loss function and then have a training goal of finding a model that optimizes for that loss function. However, as I hope the more general framework of training stories should make clear, there are many possible ways of trying to train an aligned model. Microscope AI and STEM AI are examples that I mentioned previously, but in general any approach that intends to use a loss function that would be problematic if directly optimized for, but then attempts to train a model that doesn’t directly optimize for that loss function, would fail on both outer a |

Every so often, when explaining issues related to AI safety, I call on good old Asimov. That's easy: almost everyone that is at least interested in science knows his name, and the Three Laws of Robotics are a very good example of misspecified goal. Or are they?
The truth is: I don't know. My last reading through Asimov's robots dates back ten years; it was in french; and I didn't know anything about AI safety, specification and many parts of my current mental scaffolding. So when I use Asimov for my points now, I'm not sure whether I'm spouting bullshit or not.
Fortunately, the solution is simple, for once: I just have to read the goddamn stories. And since I'm not the only one I heard talking about Asimov in this context, I thought that a sequence on the robots stories would prove useful.
My first stop is by "I,Robot", the first robot short story collection. And it starts with the first story published by Asimov, "Robbie".
Basically, this Robbie is a robot that takes care of a little girl named Gloria. All is well, until Gloria's mother turns into the bad guy, and decides that her girl should not be raised by a machine. She harasses her weak husband until he accepts to get rid of Robbie. But when Gloria discovers the loss of her friend, nothing can comfort her. The parents try everything, including a trip to New York, paradise to suburbians. But nope, the girl is still heartbroken. Last try of the father: a visit to a factory manned by robots, so little Gloria can see that they are lifeless machines, not real people. But, tada! Robbie was there! And he even saves the girl from an oncoming truck! It's revealed that the father planned it (Robbie being there, not the murder attempt on his daughter), but even so, the mother can't really send back the savior of her little girl. The End.
Just a simple story about a nice little robot beloved by a girl, and the machinations of her mother to "protect" her from him. What's not to love? It's straight to the point, nicely |
512f8257-e59c-4f75-8630-7b5b2ceeb773 | StampyAI/alignment-research-dataset/lesswrong | LessWrong | Decision theory and dynamic inconsistency
Here is my current take on decision theory:
* When making a decision after observing X, we should condition (or causally intervene) on statements like “My decision algorithm outputs Y after observing X.”
* Updating seems like a *description* of something you do when making good decisions in this way, not part of *defining* what a good decision is. ([More](https://sideways-view.com/2021/10/12/edt-with-updating-double-counts/).)
* Causal reasoning likewise seems like a *description* of something you do when making good decisions. Or equivalently: we should use a notion of causality that captures the relationships relevant to decision-making rather than intuitions about physical causality. ([More](https://sideways-view.com/2022/04/17/what-is-causality-to-an-evidential-decision-theorist/).)
* “How much do I care about different copies of myself?” is an arbitrary question about my preferences. If my preferences change over time, it naturally gives rise to dynamic inconsistency unrelated to decision theory. (Of course an agent free to modify itself at time T would benefit by implementing some efficient compromise amongst all copies forked off after time T.)
In this post I’ll discuss the last bullet in more detail since I think it’s a bit unusual, it’s not something I’ve written about before, and it’s one fo the main ways my view of decision theory has changed in the last few years.
(*Note: I think this topic is interesting, and could end up being relevant to the world in some weird-yet-possible situations, but I view it as unrelated to my day job on aligning AI with human interests*.)
The transparent Newcomb problem
-------------------------------
In the transparent version of Newcomb’s problem, you are faced with two transparent boxes (one small and one big). The small box always contains $1,000. The big box contains either $10,000 or $0. You may choose to take the contents of one or both boxes. There is a very accurate predictor, who has placed $10,000 in the big box if and only if they predict that you wouldn’t take the small box regardless of what you see in the big one.
Intuitively, once you see the contents of the big box, you really have *no* reason not to take the small box. For example, if you see $0 in the big box, you know for a fact that you are either getting $0 or $1,000. So why not just take the small box and walk away with $1,000? EDT and CDT agree about this one.
I think it’s genuinely non-obvious what you should do in this case (if the predictor is accurate enough). But I think this is because of ambiguity about what you *want*, not how you should make decision. More generally, I think that the apparent differences between EDT and UDT are better explained as differences in preferences. In this post I’ll explain that view, using transparent Newcomb as an illustration.
A simple inconsistent creature
------------------------------
Consider a simple creature which rationally pursues its goals on any given day—but whose goals change completely each midnight. Perhaps on Monday the creature is trying to create as much art and beauty as possible; on Tuesday it is trying to create joy and happiness; on Wednesday it might want something different still.
On any given day we can think of the creature as an agent. The creature on Tuesday is not being *irrational* when it decides to pursue joy and happiness instead of art and beauty. It has no special reason to try to “wind back the clock” and pursue the same projects it would have pursued on monday.
Of course on Monday the creature would prefer to arrest this predictable value drift—it knows that on Tuesday it will be replaced with a new agent, one that will stop contributing to the project of art and beauty. The creature on Monday ought to make plans accordingly, and if they had the ability to change this feature of themselves they would likely do so. It’s a matter of semantics whether we call this creature a single agent or a sequence of agents (one for each day).
This sequence of agents could benefit from cooperating with one another, and it can do so in different ways. Normal coordination is off the table, since causality runs only one way from each agent to the next. But there are still options:
* The Tuesday-creature might believe that its decision is correlated with the Monday-creature. If the Tuesday-creature tries to stop the Wednesday-creature from existing, then the Monday-creature might have tried to stop the Tuesday-creature from existing. If the correlation is strong enough and stopping values change is expensive, then the Tuesday-creature is best served by being kind to its Wednesday-self, and helping to put it in a good position to realize whatever its goals may be. (Though note that this can unwind just like an iterated prisoner’s dilemma with finite horizon!)
* The Tuesday-creature might believe that its decision is correlated with the Monday-creature’s *predictions* about what the Tuesday-creature would do. If the Tuesday-creature keeps on carrying out the Monday-creature’s plans, then the Monday-creature would be more motivated to help the Tuesday-creature succeed (and less motivated to try to prevent the value change). If the Monday-creature is a good enough predictor of the Tuesday-creature, then the Tuesday-creature is best served by at least “paying back” the Monday-creature for all of the preparation the Monday-creature did.
However none of these relationships are specific to the fact that it is the same creature on Monday and Tuesday; the fact that the cells are the same has no significance for the decision-theoretic situation. The Tuesday-creature has no intrinsic interest in the fact that it is not “reflectively stable”—of course that instability definitionally implies a desire to change itself, but not a *further* reason to try to help out the Monday-creature or Wednesday-creature, beyond the relationships described above.
A human inconsistency
---------------------
I care a lot about what is going to happen to me in the future. I care much more about my future than about different ways that the world *could have gone* (or than my past for that matter). In fact I would treat those other possible versions of myself quite similarly to how I’d treat another person who just happened to be a lot like me.
This leads to a clear temporal inconsistency, which is so natural to humans that we don’t even think of it as an inconsistency. I’ll try to illustrate with a sequence of thought experiments.
Suppose that at 7AM I think that there is a 50% chance that a bell will ring at 8AM. At 7AM I am indifferent between the happiness of Paul-in-world-with-bell and Paul-in-silent-world. If you asked me which Paul I would prefer to stub his toe, I would be indifferent.
But by 8:01AM my preferences are quite different. After I’ve heard the bell ring, I care overwhelmingly about Paul-in-world-with-bell. I would very strongly prefer that the other Paul stub his toe than that I do.
Some people might say “Well you just cared about what happens to Paul, and then at 8AM you learned what is real. Your beliefs have changed, but not your preferences.” But consider a different experiment where I am duplicated at 7AM and each copy is transported to a different city, one where the bell would ring and the other where it will not. Until I learn which city I’m in, I’m indifferent between the happiness of Paul-in-city-with–bell and Paul-in-silent-city. But at the moment when I hear the bell ring, my preferences shift.
Some people could still say “Well you cared about the same thing all along—what happens to *you*—and you were merely uncertain about which Paul was *you*.” But consider the Paul from before the instant of copying, informed that he is about to be copied. That Paul knows full well that he cares about both copies. Yet sometime between the copying and the bell Paul has become much more parochial, and only cares about one. It seems to me like there is little way to escape from the inconsistency here.
One could still say “Nonsense, all along you just cared about what happened to *you*, you were just uncertain about which of the copies *you* were going to become.” I find this very unpersuasive (why think there is a fact of the matter about who “I” am?), but at this point I think it’s just a semantic dispute. Either my preferences change, or my preferences are fixed but defined in terms of a concept like “the real me” whose *meaning* changes. It all amounts to the same thing.
This is not some kind of universal principle of rationality—it’s just a fact about Paul. You can imagine different minds who care about all creatures equally, or who care only about their own future experiences, or who care about all the nearby possible copies of themselves. But I think many humans feel roughly the same way I do—they have some concern for others (including creatures very similar to themselves in other parts of the multiverse), but have a very distinctive kind of caring for what they themselves will *actually* experience in the future.
Altruism is more complicated
----------------------------
In the examples above I discussed stubbing my toe as the unit of caring. But what if we had instead talked of dollars? And what if I am a relatively altruistic person, who would use marginal dollars to try to make the world better?
Now in the case of two copies in separate cities it is clear enough that my preferences never change. I’m still willing to pay $1 to give my counterpart $2. After all, they can spend those dollars just as well as I can, and I don’t care who it was who did the good.
But in the case of a single city, where the bell either rings or it doesn’t, we run into another ambiguity in my preferences—another question about which we need not expect different minds to agree no matter how rational they are.
Namely: once I’ve heard the bell ringing, do I care about the happiness of the creatures in the world-with-bell (given that it’s the real world, the one we are *actually* in), or do I care about the happiness of creatures in both worlds even after I’ve learned that I happen to be in one of them?
I think people have different intuitions about this. And there are further subtle distinctions, e.g. many people have different intuitions depending on whether the ringing of the bell was a matter of objective chance (where you could imagine other copies of yourself on far away worlds, or other branches, facing the same situation with a different outcome), or a matter of logical necessity where we were simply ignorant.
While some of those disagreements may settle with more discussion, I think we should be able to agree that *in principle* we can imagine a mind that works either way, that either care about people in other worlds-that-could-have-been or who don’t.
Most humans have at least some draw towards caring only about the humans in this world. So the rest of my post will focus on their situation.
Back to transparent Newcomb (or: The analogy)
---------------------------------------------
Consider again a human playing the transparent version of Newcomb’s problem. They see before them two boxes, a small one containing $1000 and a big one containing $0. They are told that the big box would have contained $10000 if a powerful predictor had guessed that they would never take the small box.
If the human cares only for their own future experiences, and would spend the money only on themselves, they have a pretty good case for taking the small box and walking away with $1000. After all, their own future experiences are either going to involve walking away with $1000 or with nothing, there is no possible world where they experience seeing an empty big box and then end up with the money after all.
Of course before taking the big box, the human would have much preferred to *commit* to never taking the small box. If they are an evidential decision theorist, they could also have just closed their eyes (curse that negative value of information!). That way they would have ended up with $10,000 instead of $1,000.
Does this mean that they have reason to take nothing after all, even after seeing the box?
I think the human’s situation is structurally identical to the inconsistent creature whose preferences change at midnight. Their problem is that in the instant when they see the empty big box, their preferences change. Once upon a time they cared about all of the possible versions of themselves, weighted by their probability. But once they see the empty big box, they cease to care at all about the versions of themselves who saw a full box. They end up in conflict with other very similar copies of themselves, and from the perspective of the human at the beginning of the process the whole thing is a great tragedy.
Just like the inconsistent creature, the human would have strongly preferred to make a commitment to avoid these shifting preferences. Just like the inconsistent creature, they might still find other ways to coordinate even after the preferences change, but it’s more contingent and challenging. Unlike the inconsistent creature, they can avoid the catastrophe by simply closing their eyes—because the preference change was caused by new information rather than by the passage of time.
The situation is most stark if we imagine the predictor running detailed simulations in order to decide whether to fill the big box. In this case, there is not one human but three copies of the human: two inside the predictor’s mind (one who sees an empty box and one who sees a full box) and one outside the predictor in the real world (seeing an empty or full box based on the results of the simulation). The problem for the human is that these copies of themselves can’t get along.
Even if you explained the whole situation to the human inside the simulation, they’d have no reason to go along with it. By avoiding taking the small box, all they can achieve is to benefit a different human outside of the simulation, who they no longer care at all about. From their perspective, better to just take the money (since there’s a 50% chance that they are outside of the simulation and will benefit by $1000).
(There are even more subtleties here if these different possible humans have preferences about their own existence, or about being in a simulation, or so on. But none of these change the fundamental bottom line.)
Altruism is still more complicated
----------------------------------
If we consider a human who wants to make money to make the world better, the situation is similar but with an extra winkle.
Now if we explain the situation to the inside human, they may not be quite so callous. Instead they might reason “If I don’t take the small box, there is a good chance that a ‘real’ human on the outside will then get $10,000. That looks like a good deal, so I’m happy to walk away with nothing.”
Put differently, when we see an empty box we might *not* conclude that predictor didn’t fill the box. Instead, we might consider the possibility that we are living inside the predictor’s imagination, being presented with a hypothetical that need not have any relationship to what’s going on out there in the real world.
The most extreme version of this principle would lead me to entertain very skeptical / open-minded beliefs about the world. In *any* decision-problem where “what I’d do if I saw X” matters for what happens in cases where X is false, I could say that there is a “version” of me in the hypothetical who sees X. So I can never really update on my observations.
This leads to [CDT=EDT=UDT](https://www.lesswrong.com/posts/WkPf6XCzfJLCm2pbK/cdt-edt-udt). For people who endorse that perspective (and have no indexical preferences), this post probably isn’t very interesting. Myself, I think I somewhat split the difference: I think explicitly about my preferences about worlds that I “know don’t exist,” roughly using the framework of this post. But I justify that perspective in significant part from a position of radical uncertainty: I’m not sure if I’m thinking about worlds that don’t exist, or if it’s *us* who don’t exist and there is some real world somewhere thinking about us.
Conclusion
----------
Overall the perspective in this post has made me feel much less confused about updatelessness. I expect I’m still wrong about big parts of decision theory, but for now I feel tentatively comfortable using UDT and don’t see the alternatives as very appealing. In particular, I no longer think that updating feels very plausible as a fundamental decision-theoretic principle, but at the same time don’t think there’s much of a reflective-stability-based argument for e.g. one-boxing in transparent Newcomb.
Most of the behaviors I associate with being “updateless” seem to really be about consistent preferences, and in particular continuing to care about worlds that are in some sense inconsistent with our observations. I believe my altruistic preferences are roughly stable in this sense (partially justified by a kind of radical epistemic humility about whether this is the “real” world), but my indexical preferences are not. The perspective in this post also more clearly frames the coordination problem faced by different copies of me (e.g. in different plausible futures) and I think has left me somewhat more optimistic about finding win-win deals. |

Why is abstraction useful? Why use a high-level model rather than a low-level model?
An example: when I type “4+3” in a python shell, I think of that as adding two numbers, not as a bunch of continuous voltages driving electric fields and current flows in little patches of metal and doped silicon. Why? Because, if I’m thinking about what will show up on my monitor after I type “4+3” and hit enter, then the exact voltages and current flows on the CPU are not relevant. This remains true even if I’m thinking about the voltages driving individual pixels in my monitor - even at a fairly low level, the exact voltages in the arithmetic-logic unit on the CPU aren’t relevant to anything more than a few microns away - *except* for the high-level information contained in the “numbers” passed in and out.
Another example: if I’m an astronomer predicting the trajectory of the sun, then I’m presumably going to treat other stars as point-masses. At such long distances, the exact mass distribution within the star doesn’t really matter - *except* for the high-level information contained in the total mass and center-of-mass location.
If I’m running a Markov-Chain Monte Carlo algorithm, then I take sample points fairly far apart in “time”. As long as they’re far enough apart, they’re roughly independent - there isn’t *any* information from one sample relevant to the next.
If I’m planning a roadtrip from San Francisco to Los Angeles, the details of my route through the Bay Area are irrelevant to planning my route within LA - *except* for the high-level information contained in my choice of highway for the middle leg of the trip and the rough time I expect to get there.
General point: abstraction, in practice, is about keeping information which is relevant to things “far away”, and throwing out everything else.

Xi, and some notion of which variables are “nearby”: each variable Xi has a set si of indices of variables considered “nearby” Xi. How si is chosen may vary by application - maybe each Xi is associated with some point in space and/or time, or maybe we’re looking at Markov blankets in a graphical model, or …
We want some high-level summary of Xi; we’ll define that by a function fi(Xi). We require that fi(Xi) contain all information relevant to things far away - i.e. X¯¯¯¯si, the variables *not* in si.
We’ll consider a few different notions of “relevance” here. First and most obvious is predictive relevance - fi(Xi) must contain all relevant information in the usual probabilistic/information-theoretic sense. Key subtlety: which information is relevant may itself depend on the values of other variables - e.g. maybe we have a conditional in a program which picks one of two variables to return. Should we keep around all information which is relevant in any possible case? All information which is relevant after averaging over some variables?
Looking back over the examples, I think the natural answer is: we’re keeping information relevant to things “far away” (i.e. variables not in si), so those are what we’re interested in. Everything within si we can average over. Examples:
* If I’m thinking about the relevance of the exact value of a particular voltage on the CPU to the output of “4+3” at a python shell, I’m happy to average over all the likely voltages of nearby wires.
* If I’m thinking about the relevance of a little piece of mass in a star to predicting the sun’s trajectory, I’m happy to average over all the other little pieces of mass.
* If I’m planning a trip from SF to LA, and figuring out the relevance of a particular detail of the route within the Bay Area, I’m happy to average over other details in the Bay Area.
Formally, our condition is:
P[X¯¯¯¯si|fi(Xi)]=P[X¯¯¯¯si|Xi]
We could even go a step further and apply the [minimal map theorems](https://www.lesswrong.com/posts/Lz2nCYnBeaZyS68Xb/probability-as-minimal-map) to find fi(Xi) containing the least possible information, although it won't necessarily be the most computationally efficient summary.
Another notion of “relevance” is causal influence - while probabilistic information is the key criteria for prediction, causal influence is the key for planning. We want to know what impact an intervention on Xi will have on far-away variables. We’re still happy to average over “nearby” variables, but there’s a new subtlety: we may also want to intervene on some of the variables far-away from Xi. For instance, if we’re planning a road-trip, we want to be able to consider possible route plans within LA - different routes would be different interventions on variables far away from SF. Our high-level model needs to hold for any of these interventions. Our criteria become:
P[X¯¯¯¯si|do(fi(Xi)=f∗i),do(Xs=X∗s)]=P[X¯¯¯¯si|do(Xi=X∗i),do(Xs=X∗s)]
… for any s⊂¯¯¯¯si, and any intervention values X∗s,f∗i,X∗i for which f∗i=f(X∗i). Here do(fi(Xi)=f∗i) means setting Xi to an arbitrary value X∗i such that fi(X∗i) = f∗i - i.e. “we just need to get to the highway by noon, the details don’t matter, we can work them out later”. This requires that the details do not, in fact, matter - i.e. P[X¯¯¯¯si|do(Xi=X∗i),do(Xs=X∗s)] has the same value for different X∗i so long as f(X∗i) remains the same. That’s what the notation do(fi(Xi)=f∗i) is expressing.
Finally, we could combine our criteria: require that any interventions on X¯¯¯¯si be supported, with either information or intervention on Xi. The criteria:
P[X¯¯¯¯si|fi(Xi),do(Xs=X∗s)]=P[X¯¯¯¯si|Xi,do(Xs=X∗s)]
P[X¯¯¯¯si|do(fi(Xi)=f∗i),do(Xs=X∗s)]=P[X¯¯¯¯si|do(Xi=X∗i),do(Xs=X∗s)]
Both of these must hold for any s⊂¯¯¯¯si, and any intervention values X∗s,f∗i,X∗i for which f∗i=f(X∗i). In that case, we can predict the effects of arbitrary interventions on Xi and any of the X¯¯¯¯si on other X¯¯¯¯si, using only the summary information present in fi(Xi). |

(Update Jan. 19: We now have an example of a successful partial run, which you can use to inform how you do your runs. Details.)
We at MIRI are soliciting help with an AI-alignment project centered around building a dataset, described below. We have $200,000 in prizes for building the first fragments of the dataset, plus an additional $1M prize/budget for anyone who demonstrates the ability to build a larger dataset at scale.
If this project goes well, then it may be the first of a series of prizes we offer for various projects.
Below, I’ll say more about the project, and about the payouts and interim support we’re offering.
The Project
Hypothesis: Language models can be made more understandable (and perhaps also more capable, though this is not the goal) by training them to produce visible thoughts.
We’d like to test this hypothesis by fine-tuning/retraining a language model using a dataset composed of thought-annotated dungeon runs. (In the manner of AI dungeon.)
A normal (un-annotated) dungeon run is a sequence of steps in which the player inputs text actions and the dungeon master responds with text describing what happened in the world as a result.
We’d like a collection of such runs, that are annotated with "visible thoughts" (visible to potential operators or programmers of the system, not to players) describing things like what just happened or is about to happen in the world, what sorts of things the player is probably paying attention to, where the current sources of plot tension are, and so on — the sorts of things a human author would think while acting as a dungeon master. (This is distinct from producing thoughts explaining what happened in the dungeon; “visible thoughts” are meant to play an active role in constructing the output.)
Once we have such a dataset, MIRI’s hope is that present or future technology will be able to train a model or model |

1 Introduction
---------------
Complex machine learning (ML) models such as Deep Neural Networks (DNNs) and Support Vector Machines (SVMs) perform very well on a wide range of tasks [[Lundberg and
Lee2016](#bib.bibx7)], but their outcomes are often are often difficult to understand by humans [[Weller2017](#bib.bibx15)]. Moreover, machine learning models cannot explain how they achieved their results. Even for experts in the field, it can be very difficult to understand what the model actually learned [[Samek et al.2016](#bib.bibx11)]. To remedy this issue, the field of eXplainable Artificial Intelligence (XAI) studies how such complex but useful models can be made more understandable [gunning2017explainable].
Achieving transparency of ML models has multiple advantages [[Weller2017](#bib.bibx15)]. For example, if a model designer knows why a model performs badly on some data, he or she can start a more informed process of resolving the performance issues [[Kulesza et al.2015](#bib.bibx5), [Papernot and
McDaniel2018](#bib.bibx9)]. However, even if a model has high performance, the users (typically non-experts in ML) would still like to know why it came to a certain output [[Miller2017](#bib.bibx8)]. Especially in high-risk domains such as defense and health care, inappropriate trust in the output may cause substantial risks and problems [[Lipton2016](#bib.bibx6), [Ribeiro et al.2016](#bib.bibx10)]. If a ML model fails to provide transparency, the user cannot safely rely on its outcomes, which hampers the model’s applicability [[Lipton2016](#bib.bibx6)]. If, however, a ML-model is able to explain its workings and outcomes satisfactorily to the user, then this would not only improve the user’s trust; it would also be able to provide new insights to the user.
For the problem of classification, recent research has developed a number of promising methods that enable classification models to explain their output [[Guidotti et al.2018](#bib.bibx2)]. Several of these methods prove to be model-independent in some way, allowing them to be applied on any existing ML classification model. However, for Reinforcement Learning (RL) models, there are relatively few methods available [[Verma et al.2018](#bib.bibx14), [Shu et al.2017](#bib.bibx13), [Hein et al.2017](#bib.bibx4)]. The scarcity of methods that enable RL agents to explain their actions and policies towards humans severely hampers the practical applications of RL-models in this field. It also diminishes the, often highly rated, value of RL to Artificial Intelligence [[Hein et al.2017](#bib.bibx4), [Gosavi2009](#bib.bibx1)]. Take for example a simple agent within a grid world that needs to reach a goal position while evading another actor who could cause termination as well as evading other static terminal states. The RL agent cannot easily explain why it takes the route it has learned as it only knows numerical rewards and its coordinates in the grid. The agent has no grounded knowledge about the ’evil actor’ that tries to prevent it from reaching its goal nor has it knowledge of how certain actions will effect such grounded concepts. These state features and rewards are what drives the agent but do not lend themselves well for an explanations as they may not be grounded concepts nor do they offer a reason why the agent behaves a certain way.
Important pioneering work has been done by Hayes and Shah [[Hayes and Shah2017](#bib.bibx3)]. They developed a method for eXplainable Reinforcement Learning (XRL) that can generate explanations about a learned policy in a way that is understandable to humans. Their method converts feature vectors to a list of predicates by using a set of binary classification models. This list of predicates is searched to find sub-sets that tend to co-occur with specific actions. The method provides information about which actions are performed when which state predicates are true. A method that uses the co-occurrence to generate explanations may be useful for small problems, but becomes less comprehensible in larger planning and control problems, because the overview of predicate and action combinations becomes too large. Also, the method addresses only what the agent does, and not why it acts as it does. In other words, the method presents the user with the correlations between states and the policy but it does not provide a motivation why that policy is used in terms of rewards, or state transitions.
This study proposes an approach to XRL that allows an agent to answer questions about its actions and policy in terms of their consequences. Other questions unique to RL are also possible, for example those that ask about the time it takes to obtain some goal or those about RL specific problems (loop behavior, lack of exploration or exploitation, etc.). However we believe that a non-expert in RL is mostly interested in the expected consequences of the agent’s learned behavior and whether the agent finds these consequences good or bad. This information can be used as an argument why the agent behaves in some way. This would allow human users to gain insight in what information the agent can perceive from a state and which outcomes it expects from an action or state visit. Furthermore, to limit the amount of information of all consequences, our proposed method aims to support contrastive explanations [[Miller2017](#bib.bibx8)]. Contrastive explanations are a way of answering causal ’why’-questions. In such questions, two potential items, the fact and foil, are compared to each other in terms of their causal effects on the world. Contrastive questions come natural between humans and offer an intuitive way of gathering motivations about why one performs a certain action instead of another [[Miller2017](#bib.bibx8)]. In our case we allow the user to formulate a question of why the learned policy πt (the ’fact’) is used instead of some other policy πf (the ’foil) that is of interest to the user. Furthermore, our proposed method translates the set of states and actions in a set of more descriptive state classes C and action outcomes O similar to that of [[Hayes and Shah2017](#bib.bibx3)]. This allows the user to query the agent in a more natural way as well as receive more informative explanations as both refer to the same concepts instead of plain features. The translation of state features to more high-level concepts and actions in specific states to outcomes, is also done in the proposed algorithm of [[Sherstov and
Stone2005](#bib.bibx12)]. The translation in this algorithm was used to facilitate transfer learning within a single action over multiple tasks and domains. In our method we used it to create a user-interpretable variant of the underlying Markov Decision Problem (MDP).
For the purpose of implementation and evaluation of our proposed method, we performed a pilot study. In this study, a number of explanation examples were presented to participants to see which of their varying properties are preferred the most. One of the properties was to see whether the participants prefer explanations about the expected consequences of a single-action or the entire policy.
2 Approach for consequence-based explanations
----------------------------------------------
The underlying Markov Decision Problem (MDP) of a RL agent consists of the tuple ⟨S,A,R,T,λ⟩. Here, S and A are the set of states (described by a feature vector) and actions respectively, R:S×A→R is the reward function and T:S×A→Pr(S) the transition function that provides a probability distribution over states. Also, λ is the discount factor that governs how much of future rewards are taken into account by the agent. This tuple provides the required information to derive the consequences of the learned policy πt or the foil policy πf from the user’s question. As one can use the transition function T to sample the effects of both πt and πf. In the case T is not explicit, one may use a separate ML model to learn it in addition to the actual agent. Through this simulation, one constructs a Markov Chain of state visits under each policy πt and πf and can present the difference to the user.
Through the simulation of future states with T, information can be gathered about state consequences. In turn, from the agent itself the state or state-action values for simulated state visits can be obtained to develop an explanation in terms of rewards. However, the issue with this approach is that the state features and rewards may not be easy to understand for a user as it would consist of possibly low-level concepts and numerical reward values or expected returns. To mitigate this issue we can apply a translation of the states and actions to a set of predefined state concepts and outcomes. These concepts can be designed to be more descriptive and informative for the potential user. A way to do this translation is by training a set of binary classifiers to recognize each outcome or state concept from the state features and taken action, a similar approach to the one from [[Hayes and Shah2017](#bib.bibx3)]. Their training can occur during the exploratory learning process of the agent. This translation allows us to use the above described method of simulating consequences and transform the state features and results of actions to more user-interpretable concepts.
###
2.1 A user-interpretable MDP
The original set of states can be transformed to a more descriptive set C according to the function k:S→C. This is similar to the approach of [[Hayes and Shah2017](#bib.bibx3)] where k consists of a number of classifiers. Also, rewards can be explained in terms of a set of action outcomes O according to t:C×A→Pr(O). This provides the results of an action in some state in terms of the concepts O. For example, the outcomes that the developer had in mind when designing the reward function R. The transformation of states and actions in state classes and outcomes is adopted from the work of [[Sherstov and
Stone2005](#bib.bibx12)] where the transformations are used to allow for transfer learning in RL. Here however, we use them as a translation towards a more user-interpretable representation of the actual MDP.
The result is the new MDP tuple ⟨S,A,R,T,λ,C,O,t,k⟩. An RL agent is still trained on S, A, R and T with λ independent of the descriptive sets C and O and functions k and t. This makes the transformation independent of the RL algorithm used to train the agent. See Figure [1](#S2.F1 "Figure 1 ‣ 2.1 A user-interpretable MDP ‣ 2 Approach for consequence-based explanations ‣ Contrastive explanations for reinforcement learning in terms of expected consequences") for an overview of this approach.

Figure 1: An overview of the proposed method, a dotted line represents a feedback loop. We assume a general reinforcement learning agent that acts upon a state s through some action a and receives a reward r. We train a transition model T that can be used to simulate the effect of actions on states. By repeatedly simulating a state si we can obtain the expected consequences γ of an entire policy. Also, the consequences of a contrastive policy consisting of an alternative courses of action af can be simulated with the same transition model T. Finally, in constructing the explanation we transform states and actions into user-interpretable concepts and construct an explanation that is contrastive.
As an example take the grid world illustrated in Figure [2](#S2.F2 "Figure 2 ‣ 2.1 A user-interpretable MDP ‣ 2 Approach for consequence-based explanations ‣ Contrastive explanations for reinforcement learning in terms of expected consequences") that shows an agent in a simple myopic navigation task. The states S are the (x,y) coordinates and the presence of a forest, monster or trap in adjacent tiles with A=Up,Down,Left,Right. R consists of a small transient penalty, a slightly larger penalty for tiles with a forest, a large penalty shared over all terminal states (traps or adjacent tiles to a monster) and a large positive reward for the finishing state. T is skewed towards the intended result with small probabilities for the other results if possible.

Figure 2: A simple RL problem where the agent has to navigate from the bottom left to the top right (goal) while evading traps, a monster and a forest. The agent terminates when in a tile with a trap or adjacent to the monster. The traps and the monster only occur in the red-shaded area and as soon as the agents enter this area the monster moves towards the agent.
The state transformation k can consist out of a set of classifiers for the predicates whether the agent is next to a forest, a wall, a trap or monster, or in the forest. Applying k to some state s∈S results in a Boolean vector c∈C whose information can be used to construct an explanation in terms of the stated predicates. The similar outcome transformation t may predict the probability of the outcomes O given a state and action. In our example, O consists of whether the agent will be at the goal, in a trap, next to the monster or in the forest. Each outcome o can be flagged as being positive o+ or negative o− purely such that they can be presented differently in the eventual explanation.
Given the above transformations we can simulate the next state of a single action a with T or even the entire chain of actions and visited states given some policy π. These can then be transformed into state descriptions C and action outcomes O to form the basis of an explanation. As mentioned, humans usually ask for contrastive questions especially regarding their actions [[Miller2017](#bib.bibx8)]. In the next section we propose a method of translating the foil in a contrastive question into a new policy.
###
2.2 Contrastive questions translated into value functions
A contrastive question consists of a fact and a foil, and its answer describes the contrast between the two from the fact’s perspective [[Miller2017](#bib.bibx8)]. In our case, the fact consists of the entire learned policy πt, a single action from it at=πt(st) or any number of consecutive actions from πt. We propose a method of how one can obtain a foil policy πf based on the foil in the user’s question. An example of such a question could be (framed within the case of Figure [2](#S2.F2 "Figure 2 ‣ 2.1 A user-interpretable MDP ‣ 2 Approach for consequence-based explanations ‣ Contrastive explanations for reinforcement learning in terms of expected consequences"));
>
> ”Why do you move up and then right (fact) instead of moving to the right until you hit a wall and then move up (foil)?”
>
>
>
The foil policy πf is ultimately obtained by combining a state-action value function QI – that represents the user’s preference for some actions according to his/her question – with the learned Qt to obtain Qf;
| | | | |
| --- | --- | --- | --- |
| | Qf(s,a)=Qt(s,a)+QI(s,a), ∀s,a∈S,A | | (1) |
Each state-action value is of the form Q:S×A→R.
QI only values the state-action pairs queried by the user. For instance, the QI of the above given user question can be based on the following reward scheme for all potentially simulated s∈S;
* The action a1f='Right' receives a reward such that Qf(s,Right)>Qt(s,πt(s))
* If 'RightWall'∈k(s)
* Then the action a2f='Up' receives a reward such that Qf(⋅,Up)>Qt(⋅,πt(s)).
Given this reward scheme we can train QI and obtain Qf according to equation [1](#S2.E1 "(1) ‣ 2.2 Contrastive questions translated into value functions ‣ 2 Approach for consequence-based explanations ‣ Contrastive explanations for reinforcement learning in terms of expected consequences"). The state-action values Qf can then be used to obtain the policy πf using the original action selection mechanism of the agent. This results in a policy that tries to follow the queried policy as best as it can. The advantage of having πf constructed from Qf is that the agent is allowed to learn a different action then those in the user’s question as long as the reward is higher in the long run (more user defined actions can be performed). Also, it allows for the simulation of the actual expected behavior of the agent as it is still based on the agent’s action selection mechanism. This would both not be the case if we simply forced the agent to do exactly what the user stated.
The construction of QI is done through simulation with the help of the transition model T. The rewards that are given during the simulation are selected with Equation [1](#S2.E1 "(1) ‣ 2.2 Contrastive questions translated into value functions ‣ 2 Approach for consequence-based explanations ‣ Contrastive explanations for reinforcement learning in terms of expected consequences") in mind, as they need to eventually compensate for the originally learned action based on Qt. Hence, the reward for each state and queried action is as follows;
| | | | |
| --- | --- | --- | --- |
| | RI(si,af)=λfλw(si,st)[R(si,af)−R(si,at](1+ϵ) | | (2) |
With at=πt(st) the originally learned action and w being a distance based weight;
| | | | |
| --- | --- | --- | --- |
| | w(si,st)=e−(d(si,st)σ)2 | | (3) |
First, si with i∈{t,t+1,...,t+n} is the i’th state in the simulation starting with st. af is the current foil action governed by the conveyed policy by the user. The fact that af is taken as the only rewarding action each time, greatly reduces the time needed to construct QI. Next, w(si,st) is obtained from a Radial Basis Function (RBF) with a Gaussian kernel and distance function d. This RBF represents the exponential distance between our actual state st and the simulated state si. The Gaussian kernel is governed by the standard deviation σ and allows us to reduce the effects of QI as we get further from our actual state st. The ratio of discount factors λfλ allows for the compensation between the discount factor λ of the original agent and the potentially different factor λf for QI if we wish it to be more shortsighted. Finally, [R(si,af)−R(si,at)](1+ϵ) is the amount of reward that af needs such that QI(si,af)ϵ>Q(si,at). With ϵ>0 that determines how much more QI will prefer af over at.
The parameter n defines how many future state transitions we simulate and are used to retrieve QI. As a general rule n≥3σ as at this point the Gaussian kernel will reduce the contribution of QI to near zero such that Qf will resemble Qt. Hence, by setting σ one can vary the number of states the foil policy should starting from st. Also, by setting ϵ the strength of how much each af should be preferred over at can be regulated. Finally, λf defines how shortsighted QI should be. If set to λf=0, πf will force the agent to perform af as long as si is not to distant from st. If set to values near one, πf is allowed to take different actions as long as it results into more possibilities of performing af.
###
2.3 Generating explanations
At this point we have the user-interpretable MDP consisting of state concepts C and action outcomes O provided by their respective transformation function k and t. Also, we have a definition of RI that values the actions and/or states that are of interest by the user which can be used to train QI through simulation and obtain Qf according to Equation [1](#S2.E1 "(1) ‣ 2.2 Contrastive questions translated into value functions ‣ 2 Approach for consequence-based explanations ‣ Contrastive explanations for reinforcement learning in terms of expected consequences"). This provides us with the basis of obtaining the information needed to construct an explanation.
As mentioned before, the explanations are based on simulating the effects with T of πt and that of πf (if defined by the user). We can call T on the previous state si−1 for some action π(si−1 to obtain si and repeat this until i==n. The result is a single sequence or trajectory of visited states and performed actions for any policy π starting from st;
| | | | |
| --- | --- | --- | --- |
| | γ(st,π)={(s0,a0),...,(sn,an)∣T,π} | | (4) |
If T is probabilistic, multiple simulations with the same policy and starting state may result in different trajectories. To obtain the most probable trajectory γ(st,π)∗ we can take the transition from T with the highest probability. Otherwise a Markov chain could be constructed instead of a single trajectory.
The next step is to transform each state and action pair in γ(st,π)∗ to the user-interpretable description with the functions k and t;
| | | | |
| --- | --- | --- | --- |
| | Path(st,π)={(c0,o0),...,(cn,on)}, ci=k(si), oi=t(si,ai),(si,ai)∈γ(st,π)∗ | | (5) |
From Path(st,πt) an explanation can be constructed about the state the agent will most likely visit and the action outcomes it will obtain. For example with the use of the following template;
>
> ”For the next n actions I will mostly perform a. During these actions, I will come across situations with ∀c∈Path(st,πt). This will cause me ∀o+∈Path(st,πt) but also ∀o−∈Path(st,πt)”.
>
>
>
Let a here be the action most common in γ(st,πt) and both o+ and o− the positive and negative action outcomes respectively. Since we have access to the entire simulation of πf, a wide variety of explanations is possible. For instance we could also focus on the less common actions;
>
> ”For the next n actions I will perform a1 when in situations with ∀c∈Path(st,πt|πt=a1) and a2 when in situations with ∀c∈Path(st,πt|πt=a2). These actions prevent me from ∀o+∈Path(st,πt) but also ∀o−∈Path(st,πt)”.
>
>
>
A contrastive explanation given some question from the user that describes the foil policy πf can be constructed in a similar manner but take the contrast. Given a foil we can focus on the differences between Path(st,πt) and Path(st,πf). This can be obtained by taking the relative complement Path(st,πt)∖Path(st,πf); the set of expected unique consequences when behaving according to πt and not πf. A more extensive explanation can be given by taking the symmetric difference Path(st,πt)△Path(st,πf) to explain the unique differences between both policies.
3 User study
-------------
The above proposed method allows an RL agent to explain and motivate its behavior in terms of expected states and outcomes. It also enables the construction of contrastive explanations where any policy can be compared to the learned policy. This contrastive explanation is based on differences in expected outcomes between the compared policies.
We performed a small user study in which 82 participants were shown a number of exemplar explanations about the case shown in figure [2](#S2.F2 "Figure 2 ‣ 2.1 A user-interpretable MDP ‣ 2 Approach for consequence-based explanations ‣ Contrastive explanations for reinforcement learning in terms of expected consequences"). These explanations addressed either the single next action or the policy. Both explanations can be generated by the above method by adjusting the Radial Basis Function weighting scheme and/or the foil’s discount factor. Also, some example explanations were contrastive with only the second best action or policy, while others provided all consequences. Contrasts were determined using the relative complement between fact and foil. Whether the learned action or policy was treated as the fact or foil, was also systematically manipulated in this study.
We presented the developed exemplar explanations in pairs to the participants and asked them to select the explanation that helped them most to understand the agent’s behavior. Afterwards we asked which of the following properties they used to assess their preference: long versus short explanations; explanations with ample information versus little information; explanations addressing actions versus those that address strategies (policies); and explanations addressing short-term consequences of actions versus explanations that address distant consequences of actions.
The results of the preferred factors are shown in Figure [3](#S3.F3 "Figure 3 ‣ 3 User study ‣ Contrastive explanations for reinforcement learning in terms of expected consequences"). This shows that the participants prefer explanations that address strategy and policy, and that provide ample information. We note here that, given the simple case from figure [2](#S2.F2 "Figure 2 ‣ 2.1 A user-interpretable MDP ‣ 2 Approach for consequence-based explanations ‣ Contrastive explanations for reinforcement learning in terms of expected consequences"), participants may have considered an explanation addressing a single action only as trivial, because the optimal action was, in most cases, already evident to the user.

Figure 3: A plot depicting the percentage of participants (y-axis) for each explanation property (x-axis) that caused them to prefer some explanations over others. Answers of a total of 82 participants where gathered.
4 Conclusion
-------------
We proposed a method for a reinforcement learning (RL) agent to generate explanations for its actions and strategies. The explanations are based on the expected consequences of its policy. These consequences were obtained through simulation according to a (learned) state transition model. Since state features and numerical rewards do not lend themselves easily for an explanation that is informative to humans, we developed a framework that translates states and actions into user-interpretable concepts and outcomes.
We also proposed a method for converting the foil, –or policy of interest to the user–, of a contrastive ’why’-question about actions into a policy. This policy follows locally the user’s query but gradually transgresses back towards the original learned policy. This policy favors the actions that are of interest to the user such that the agent tries to perform them as best as possible. How much these actions are favored compared to the originally learned action can be set with a single parameter.
Through running simulations for a given number steps of both the policy derived from the user’s question and the actually learned policy, we were able to obtain expected consequences of each. From here, we were able to construct contrastive explanations: explanations addressing the consequences of the learned policy and what would be different if the derived policy would have been followed.
An online survey pilot study was conducted to explore which of several explanations are most preferred by human users. Results indicate that users prefer explanations about policies rather than about single actions.
Future work will focus on implementing the method on complex RL benchmarks to explore the scalability of this approach in realistic cases. This is important given the computational costs of simultaneously simulating the consequences of different policies in large state spaces. Also, we will explore more methods to construct our translation functions from states and actions to concepts and outcomes. A more extensive user study will be carried out to evaluate the instructional value of generated explanations in more detail, and to explore the relationship between explanations and users’ trust in the agent’s performance.

(Half-baked)
Much has been said about slack on this site, starting with Zvi's seminal post. The point I couldn't find easily (probably missed) is that an aligned AI would need a fair bit of it. Having a utility function means zero slack: there is one thing you optimize, to the exclusion of everything else. And all precisely defined goals are necessarily Goodharted (or, in the DnD terms, munchkined). An AI armed with a utility function will tile the world (the whole world, or its own "mental" world, or both) with smiley paperclips. For an AI (or for a natural intelligence) to behave non-destructively it needs room to satisfice, not optimize. Optimal utility corresponds to a single state of the world among infinitely many, while adding slack to the mix expands the space of acceptable world state enough to potentially include those that are human-aligned. If an AGI is indifferent between a great many world states, it might well include some that would be acceptable to humanity and have no incentive to try to trick its creators. Not being an ML person, I have no idea how to formalize it, or if it has been formalized already. But figured it's worth writing a short note about. That is all. |

Various people have said that Solomonoff Induction (SI) accords with the Self-Sampling Assumption (SSA) more than the Self-Indicating Assumption (SIA). See these posts and the comments on them:

https://www.lesswrong.com/posts/sEij9C9MnzEs8kaBc/the-presumptuous-philosopher-self-locating-information-and
I was surprised, because I like both SI and SIA. Both seem correct to me, and I carefully considered the apparent contradiction. I believe that I have dissolved the contradiction, and that SI, properly applied, actually implies SIA. I can't actually prove this broad claim, but I will at least argue that SI is a thirder in Sleeping Beauty, and gesture in the direction of what I think is wrong with the claims in the linked post. As a bonus, if you read till the end I'll throw in an intuition-generator for why SIA actually gives the correct answer in Presumptuous Philosopher.
First, let me reconstruct the contradiction in the Sleeping Beauty context, and explain why it might seem that SI is a halfer.
Naive view:
There are three possible outcomes: Monday-Tails (MT), Monday-Heads (MH) and Tuesday-Heads (TH). Each of these three outcomes are equally simple, therefore the machines encoding each will get equal weighting and the probabilities are all 1/3.
Antithesis:
MT is actually simpler than MH. Why? Because if you know that it was heads, you still need to be told that it's Monday - but if you know that it's tails, then you already know that it's Monday. MT is one bit simpler than MH and therefore is twice as likely, under SI. SI is a halfer. Note that this is roughly the same argument as in the Presumptuous Philosopher post - it takes more information to encode "where you are" if there's many copies of you.
Synthesis:
Wait a minute. By equivalent logic, TH is simpler than MH - if you know that it's Tuesday, you automatically know that it was heads! TH is |

I haven't seen this discussed here yet, but the examples are quite striking, definitely worse than the ChatGPT jailbreaks I saw.
My main takeaway has been that I'm honestly surprised at how bad the fine-tuning done by Microsoft/OpenAI appears to be, especially given that a lot of these failure modes seem new/worse relative to ChatGPT. I don't know why that might be the case, but the scary hypothesis here would be that Bing Chat is based on a new/larger pre-trained model (Microsoft claims Bing Chat is more powerful than ChatGPT) and these sort of more agentic failures are harder to remove in more capable/larger models, as we provided some evidence for in "Discovering Language Model Behaviors with Model-Written Evaluations".
Examples below (with new ones added as I find them). Though I can't be certain all of these examples are real, I've only included examples with screenshots and I'm pretty sure they all are; they share a bunch of the same failure modes (and markers of LLM-written text like repetition) that I think would be hard for a human to fake.

4164e72f-a9c4-4168-9db2-fe2f49585fdd | trentmkelly/LessWrong-43k | LessWrong | An alignment safety case sketch based on debate
This post presents a mildly edited form of a new paper by UK AISI's alignment team (the abstract, introduction and related work section are replaced with an executive summary). Read the full paper here.
Executive summary
AI safety via debate is a promising method for solving part of the alignment problem for ASI (artificial superintelligence).
TL;DR Debate + exploration guarantees + solution to obfuscated arguments + good human input solves outer alignment. Outer alignment + online training solves inner alignment to a sufficient extent in low-stakes contexts.
This post sets out:
* What debate can be used to achieve.
* What gaps remain.
* What research is needed to solve them.
These gaps form the basis for one of the research agendas of UK AISI’s new alignment team: we aim to dramatically scale up ASI-relevant research on debate. We’ll also use the technique in this post – safety case sketching – to develop research agendas in other areas.
Debate is a potential solution to scalable oversight: how can we correctly reward desired behaviours for superhuman systems? In particular, it is often going to be beyond humans' ability to efficiently judge whether the behaviour of a superhuman system is desirable (or judge if a justification provided by the superhuman system is valid). Solving scalable oversight effectively provides a solution to outer alignment.
We’re optimistic that outer alignment is useful, despite inner alignment problems. Specifically, outer alignment with exploration guarantees gets you a deployment-time error bound that allows you to prove regret bounds for online training. In other words, outer alignment upper bounds the proportion of model outputs that are misaligned, as long as the model does not deliberately underperform during training. This upper bound can be maintained during deployment if a system is trained continuously. So, in low-stakes contexts where a small number of mistakes are acceptable such that you can use online trai |

Introduction
The selection theorems agenda aims to prove statements of the following form: "agents selected under criteria X has property Y," where Y are things such as world models, general purpose search, modularity, etc. We're going to focus on world models.
But what is the intuition that makes us expect to be able to prove such things in the first place? Why expect world models?
Because: assuming the world is a Causal Bayesian Network with the agent's actions corresponding to the D (decision) node, if its actions can robustly control the U (utility) node despite various "perturbations" in the world, then intuitively it must have learned the causal structure of how U's parents influence U in order to take them into account in its actions.
And the same for the causal structure of how U's parents' parents influence U's parents ... and by induction, it must have further learned the causal structure of the entire world upstream of the utility variable.
This is the intuitive argument that the paper Robust Agents Learn Causal World Model by Jonathan Richens and Tom Everitt formalizes.
Informally, its main theorem can be translated as: if an agent responds to various environment interventions by prescribing policies that overall yield low regret, then it's possible to appropriately query the agent to reconstruct an implicit world model that matches up with the ground truth causal structure.
I will refer to this result as the "Causal Good Regulator Theorem". This sequence Thoughts on the Causal Good Regulator Theorem will do the following:
* [1] a precise statement of the theorem alongside a high-level argument of its proof and discussions of the paper's results in the context of the selection theorem agenda - basically a self-complete distillation of the paper. The rest of the posts in this |
f9c52d57-6242-4692-9c39-64c02199f000 | trentmkelly/LessWrong-43k | LessWrong | AI #65: I Spy With My AI
In terms of things that go in AI updates, this has been the busiest two week period so far. Every day ends with more open tabs than it started, even within AI.
As a result, some important topics are getting pushed to whenever I can give them proper attention. Triage is the watchword.
In particular, this post will NOT attempt to cover:
1. Schumer’s AI report and proposal.
1. This is definitely RTFB. Don’t assume anything until then.
2. Tyler Cowen’s rather bold claim that May 2024 will be remembered as the month that the AI safety movement died.
1. Rarely has timing of attempted inception of such a claim been worse.
2. Would otherwise be ready with this but want to do Schumer first if possible.
3. He clarified to me that he has walked nothing back.
4. Remarkably quiet all around, here is one thing that happened.
3. Anthropic’s new interpretability paper.
1. Potentially a big deal in a good way, but no time to read it yet.
4. DeepMind’s new scaling policy.
1. Initial reports are it is unambitious. I am reserving judgment.
5. OpenAI’s new model spec.
1. It looks solid as a first step, but pausing until we have bandwidth.
6. Most ongoing issues with recent fallout for Sam Altman and OpenAI.
1. It doesn’t look good, on many fronts.
2. While the story develops further, if you are a former employee or have a tip about OpenAI or its leadership team, you can contact Kelsey Piper at kelsey.piper@vox.com or on Signal at 303-261-2769.
7. Also: A few miscellaneous papers and reports I haven’t had time for yet.
My guess is at least six of these eight get their own posts (everything but #3 and #8).
So here is the middle third: The topics I can cover here, and are still making the cut.
Still has a lot of important stuff in there.

Consciousness is primarily sentience. There may be parts of it that aren't, but I haven't managed to pin any down - consciousness all seems to be about feelings, some of them being pleasant or unpleasant, but others like colour qualia are neutral, as is the feeling of being conscious. There is a major problem with sentience though, and I want to explore that here, because there are many people who believe that intelligent machines will magically become sentient and experience feelings, and even that the whole internet might do so. However, science has not identified any means by which we could make a computer sentient (or indeed have any kind of consciousness at all).
It is fully possible that the material of a computer processor could be sentient, just as a rock may be, but how would we ever be able to know? How can a program running on a sentient processor detect the existence of that sentience? There is no "read qualia" machine code instruction for it to run, and we don't know how to build any mechanism to support such an instruction.
Picture a "sentient" machine which consists of a sensor and a processor which are linked by wires, but the wires pass through a magic box where a sentience has been installed. If the sensor detects something damaging, it sends a signal down a "pain" wire. When this signal reaches the magic box, pain is experienced by something in the box, so it sends a signal on to the processor down another pain wire. The software running on the processor receives a byte of data from a pain port and it might cause the machine to move away from the thing that might damage it. If we now remove the magic box and connect the "pain" wire to the pain wire, the signal can pass straight from the sensor to the processor and generate the same reaction. The experience of pain is unnecessary.
Worse still, we can also have a pleasure sensor wired up to the same magic box, and when something tasty like a battery is encountered, a "pleasure" signal is sent to |

Political polarization in the USA has been increasing for decades, and has become quite severe. This may have a variety of causes, but it seems highly probable that the internet has played a large role, by facilitating the toxoplasma of rage to an unprecedented degree.
Recently I have the (wishful) feeling that the parties have moved so far apart that there is "room in the center". The left is for people who are fed up with the extremes of the right. The right is for people who are fed up with the extremes of the left. But where do people go if they've become fed up with both extremes?
The question is: how would the new center work? There's not room for a new political party; plurality voting makes that too difficult, because if the new party doesn't gain more than 1/3rd of the vote, it's basically a wasted vote.
Here is my proposal for what it could look like:
* Rather than operating as a traditional political party, New Center would attempt to be a formalized group of swing voters: it makes recommendations about which candidates from other parties to vote for. Given how some elections are consistently very close (most notably, the US presidential election), New Center might be able to achieve a kingmaker status even with only a relatively small portion of voters.
* In order to accomplish this, New Center has to make recommendations which credibly represent centrist values (and only centrist values).
* The New Center needs a strong set of criteria by which it judges politicians. These criteria must be based on a critique of the extreme left and the extreme right, to capture people's frustrations with both sides.
* Registering with the movement might involve pledging your vote to their recommended candidates. In return, registering might give you a voice in the selection process.
* For example, New Center candidates might be selected by New Center members rating other party's candidates on each New Center criterion. Of course this process is easily manipu |

Epistemic Status: Probably not generalisable to everyone, applies especially strong to me
It's very easy to decide to do something in the abstract on the basis that it should give you some particular skills. Here are some personal examples where I didn't get what I wanted out of my time:
* Taking a class on art history
* Reading a bunch of articles on philosophy
* Studying a degree in psychology
* Watching a bunch of short videos about history
* Reading a book on human rights
These failure were basically my fault as I either just consumed the information or crammed any study I did do. Obviously I knew that this was less than ideal.
What I didn't realise was that I'd get basically nothing out of these activities. That I wouldn't be any better about talking about art, that I'd end up with only vague recollections of most of the philosophers, that I wouldn't have much more insight into psychology than someone who spent their time on Reddit, ect.
This isn't just limited to intellectual activities. I had the same experience with Salsa where I did a lot of classes, but never really put time into the basic skills. I learned more moves, but my basic skills really didn't improve.
The assumption I made in each of these cases was, "Surely doing X makes people better at Y, so I just have to do X and I'll get better at Y, maybe not as much as if I did Z, but it should still have a reasonable effect".
However, in my experience it doesn't work like that. You'll likely think it's working at the time, but any gains are unlikely to persist.
Instead, it's important to be iterative. Instead I suggest the following: Do something, see where you are improving and where you are not and then adjust. Repeat until you get the results you want.
This probably sounds stupidly obvious, but these things are easy to overlook when you are inside a situation. |
38d1aa53-2ada-47d9-a495-37acb3ce7b4b | trentmkelly/LessWrong-43k | LessWrong | Dissolution of free will as a call to action
Accepting determinism and the insuing dissolution of free will is often feared as something that would lead to loss of will and fatalism. Gary Drescher and Eliezer spend considerable effort explaining this as a fallacy.
The one thing I don't remember mentioned is the opposite effect (but maybe I missed it) - if you experienced a failure to accomplish something, the free will explanation is likely to make you stop investigating the root cause, leaving it as a mystery. Once you accept determinism you know that a failure is determined by your mental algorithms, and should be much more motivated to push the investigation further, making yourself stronger. |
c2ce8153-6655-4d42-ab17-6fca61e3a683 | trentmkelly/LessWrong-43k | LessWrong | My problems with Formal Friendly Artificial Intelligence work
I'm writing this to get information about the lesswrong community and whether it worth engaging. I'm a bit out of the loop in terms of what the LW community is like and whether it can maintain multiple view points (and how known the criticisms are).
The TL;DR is I have problems with treating computation in an overly formal fashion. The more pragmatic philosophy suggested implies (but doesn't prove) that AI will not be as powerful as expected as the physicality of computation is important and instantiating computing in a physical fashion is expensive.
I think all the things I will talk about are interesting, but I don't see the sufficiency of them when considering AI running in the real world in real computers.
1. Source code based decision theory
I don't understand why:
* other agents trust that your source code is what you say it is
* other agents trust that your implementation of your interpreter matches their understanding of the interpreter. I don't see how they get round trustless trust (inserting code/behaviour via malicious compiler/interpreter) issues when they don't have the ability to do diverse compilation.
I understand the justification that causal decision theory is not optimal and you want something better. But it seems that whatever that better thing is has to be able to adapt to conditions. If people start baking in TDT or UDT into the core of their AIs philosophy for all eternity, they can be tricked by machines that 99% the time run the source code they purport to run as expected, but not when the fate of the galaxy decisions are being made. You need a system that can start to do hardware verification on an ad hoc basis if the problems it comes across in the environment warrant it.
2. General Functionalism
The idea that it doesn't matter how you compute something just whether the inputs and outputs are the same.

1c77e7ce-884d-49a5-b479-a4355c1a61e3 | trentmkelly/LessWrong-43k | LessWrong | Call For Distillers
Many technical alignment researchers are bad-to-mediocre at writing up their ideas and results in a form intelligible to other people. And even for those who are reasonably good at it, writing up a good intuitive explanation still takes a lot of work, and that work lengthens the turn-time on publishing new results. For instance, a couple months ago I wrote a post which formalized the idea of abstractions as redundant information, and argued that it’s equivalent to abstractions as information relevant at a distance. That post came out about two months after I had the rough math worked out, because it took a lot of work to explain it decently - and I don’t even think the end result was all that good an explanation! And I still don’t have a post which explains well why that result is interesting.
I think there’s a lot of potential space in the field for people who are good at figuring out what other researchers’ math is saying intuitively, and why it’s interesting, and then communicating that clearly - i.e. the skill of distillation. This post will briefly sketch out what two kinds of distillation roles might look like, what skills are needed, and talk about how one might get started in such a role.
Two Distiller Roles
The two types of distiller role I’ll sketch are:
* “Independent” distiller: someone who works independently, understanding work published by other researchers and producing distillations of that work.
* “Adjunct” distiller: someone who works directly with one researcher or a small team, producing regular write-ups of what the person/team is thinking about and why.
These two roles add value in slightly different ways.
An independent distiller’s main value-adds are:
* Explaining the motivation and intended applications
* Coming up with new examples
* Boiling down the “key intuitive story” behind an argument
* Showing how the intuitive story fits into the context of the intended applications
I expect the ability to come up with novel examples |
29b0806a-c65d-40e9-ade5-5e092422f799 | trentmkelly/LessWrong-43k | LessWrong | Global Workspace Theory
Much research has been done upon visual perception. Humans have the illusion that they are directly aware of everything in their 'field of view', but it turns out that they actually navigate not through reality, but through a model of reality that their brain stitches together mainly from the bits the eye is directly looking at as it darts about, with the rest supplied by interpolation based upon expectations.
For more info, read The Illusion of Continuity: Active Perception and the Classical Editing System, by Berliner and Cohen.
Global Workspace Theory is the idea that our awareness of our own thought process works the same way. We have the illusion of an unbroken stream of consciousness, but what we're actually referencing is a model of what the brain thinks it has been consciously thinking about, that is stitched together from brief fragments, the way a spotlight in a theatre might move about shining on different parts of a stage, revealing actors making speeches and interacting with each other. Even when the spotlight moves on, the actors, stage hands and directors remain and keep working. When the spotlight returns, to catch a later part of the drama in that area, we interpolate what the actors would have been doing while we were paying attention elsewhere. |
ac511464-4bb5-4611-962f-f573e3f65b91 | StampyAI/alignment-research-dataset/eaforum | Effective Altruism Forum | Spreading messages to help with the most important century
In the [most important century](https://forum.effectivealtruism.org/s/isENJuPdB3fhjWYHd) series, I argued that the 21st century could be the most important century ever for humanity, via the development of advanced AI systems that could dramatically speed up scientific and technological advancement, getting us more quickly than most people imagine to a deeply unfamiliar future.
In [this more recent series](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w), I’ve been trying to help answer this question: **“So what? What can I do to help?”**
So far, I’ve just been trying to build a picture of some of the major risks we might face (especially the [risk of misaligned AI](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/vGsRdWzwjrFgCXdMn) that [could defeat all of humanity](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/6LTh4foNuC3NdtmZH)), what might be [challenging about these risks](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/NbiHKTN5QhFFfjjm5), and [why we might succeed anyway](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/rJRw78oihoT5paFGd). Now I’ve finally gotten to the part where I can start laying out tangible ideas for how to help (beyond the [pretty lame suggestions](https://forum.effectivealtruism.org/posts/uNczpTHFvjt4KNxEF/call-to-vigilance) I gave before).
This piece is about one broad way to help: **spreading messages** that ought to be more widely understood.
One reason I think this topic is worth a whole piece is that **practically everyone can help with spreading messages at least some,** via things like talking to friends; writing explanations of your own that will appeal to particular people; and, yes, posting to Facebook and Twitter and all of that. Call it slacktivism if you want, but I’d guess it can be a big deal: many extremely important AI-related ideas are understood by vanishingly small numbers of people, and a bit more awareness could snowball. Especially because these topics often feel too “weird” for people to feel comfortable talking about them! Engaging in credible, reasonable ways could contribute to an overall background sense that it’s *OK to take these ideas seriously.*
And then there are a lot of potential readers who might have *special* opportunities to spread messages. Maybe they are professional communicators (journalists, bloggers, TV writers, novelists, TikTokers, etc.), maybe they’re non-professionals who still have sizable audiences (e.g., on Twitter), maybe they have unusual personal and professional networks, etc. Overall, the more you feel you are good at communicating with some important audience (even a small one), the more this post is for you.
That said, **I’m not excited about blasting around hyper-simplified messages.** As I hope this series has shown, the challenges that could lie ahead of us are complex and daunting, and shouting stuff like “AI is the biggest deal ever!” or “AI development should be illegal!” could do more harm than good (if only by associating important ideas with being annoying). Relatedly, I think it’s generally **not good enough to spread the most broad/relatable/easy-to-agree-to version of each key idea,** like “AI systems could harm society.” Some of the unintuitive details are crucial.
Instead, the **gauntlet I’m throwing is: “find ways to help people understand the core parts of the challenges we might face, in as much detail as is feasible.”** That is: the goal is to try to help people get to the point where they could maintain a reasonable position in a detailed back-and-forth, not just to get them to repeat a few words or nod along to a high-level take like “AI safety is important.”This is a **lot** harder than shouting “AI is the biggest deal ever!”, but I think it’s worth it, so I’m encouraging people to rise to the challenge and stretch their communication skills.
Below, I will:
* Outline some general challenges of this sort of message-spreading.
* Go through some ideas I think it’s risky to spread too far, at least in isolation.
* Go through some of the ideas I’d be most excited to see spread.
* Talk a little bit about how to spread ideas - but this is mostly up to you.
Challenges of AI-related messages
---------------------------------
Here’s a simplified story for how spreading messages could go badly.
* You’re trying to convince your friend to care more about AI risk.
* You’re planning to argue: (a) AI could be really powerful and important within our lifetimes; (b) Building AI too quickly/incautiously could be dangerous.
+ Your friend just isn’t going to *care* about (b) if they aren’t sold on some version of (a). So you’re starting with (a).
* Unfortunately, (a) is easier to understand than (b). So you end up convincing your friend of (a), and not (yet) (b).
* Your friend announces, “Aha - I see that AI could be tremendously powerful and important! I need to make sure that people/countries I like are first to build it!” and runs off to help build powerful AI as fast as possible. They’ve chosen the [competition frame (“will the right or the wrong people build powerful AI first?”) over the caution frame](https://forum.effectivealtruism.org/s/isENJuPdB3fhjWYHd/p/Lbtcjfxhrs8kfKK2M) (“will we screw things up and all lose?”), because the competition frame is [easier to understand](https://forum.effectivealtruism.org/s/isENJuPdB3fhjWYHd/p/Lbtcjfxhrs8kfKK2M#Why_I_fear__competition__being_overrated__relative_to__caution_).
* Why is this bad? [See previous pieces](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w) on the importance of caution.
(Click to expand) More on the “competition” frame vs. the “caution” frame”
In a [previous piece](https://forum.effectivealtruism.org/s/isENJuPdB3fhjWYHd/p/Lbtcjfxhrs8kfKK2M), I talked about two contrasting frames for how to make the best of the most important century:
**The caution frame.** This frame emphasizes that a furious race to develop powerful AI could end up making *everyone* worse off. This could be via: (a) AI forming [dangerous goals of its own](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/vGsRdWzwjrFgCXdMn) and [defeating humanity entirely](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/6LTh4foNuC3NdtmZH); (b) humans racing to gain power and resources and “[lock in](https://forum.effectivealtruism.org/posts/AKxKR4CeakyBsGFoH/digital-people-would-be-an-even-bigger-deal#Lock_in)” their values.
Ideally, everyone with the potential to build something [powerful enough AI](https://forum.effectivealtruism.org/s/isENJuPdB3fhjWYHd/p/AmxxnazJcBWzWEeqj) would be able to pour energy into building something safe (not misaligned), and carefully planning out (and negotiating with others on) how to roll it out, without a rush or a race. With this in mind, perhaps we should be doing things like:
* Working to improve trust and cooperation between major world powers. Perhaps via AI-centric versions of [Pugwash](https://en.wikipedia.org/wiki/Pugwash_Conferences_on_Science_and_World_Affairs) (an international conference aimed at reducing the risk of military conflict), perhaps by pushing back against hawkish foreign relations moves.
* Discouraging governments and investors from shoveling money into AI research, encouraging AI labs to thoroughly consider the implications of their research before publishing it or scaling it up, working toward [standards and monitoring](https://forum.effectivealtruism.org/posts/XRphCh6NbfQiDF3Nt/racing-through-a-minefield-the-ai-deployment-problem#Global_monitoring__noticing_people_about_to_step_on_mines__and_stopping_them_), etc. Slowing things down in this manner could buy more time to do research on avoiding [misaligned AI](https://forum.effectivealtruism.org/s/isENJuPdB3fhjWYHd/p/Lbtcjfxhrs8kfKK2M#Worst__Misaligned_AI), more time to build trust and cooperation mechanisms, and more time to generally gain strategic clarity
**The “competition” frame.** This frame focuses less on how the transition to a radically different future happens, and more on who's making the key decisions as it happens.
* If something like [PASTA](https://forum.effectivealtruism.org/s/isENJuPdB3fhjWYHd/p/AmxxnazJcBWzWEeqj) is developed primarily (or first) in country X, then the government of country X could be making a lot of crucial decisions about whether and how to regulate a potential explosion of new technologies.
* In addition, the people and organizations leading the way on AI and other technology advancement at that time could be especially influential in such decisions.
This means it could matter enormously "who leads the way on transformative AI" - which country or countries, which people or organizations.
Some people feel that we can make confident statements today about which specific countries, and/or which people and organizations, we should hope lead the way on transformative AI. These people might advocate for actions like:
* Increasing the odds that the first PASTA systems are built in countries that are e.g. less authoritarian, which could mean e.g. pushing for more investment and attention to AI development in these countries.
* Supporting and trying to speed up AI labs run by people who are likely to make wise decisions (about things like how to engage with governments, what AI systems to publish and deploy vs. keep secret, etc.)
**Tension between the two frames.** People who take the "caution" frame and people who take the "competition" frame often favor very different, even contradictory actions. Actions that look important to people in one frame often look actively harmful to people in the other.
For example, people in the "competition" frame often favor moving forward as fast as possible on developing more powerful AI systems; for people in the "caution" frame, haste is one of the main things to avoid. People in the "competition" frame often favor adversarial foreign relations, while people in the "caution" frame often want foreign relations to be more cooperative.
That said, this dichotomy is a simplification. Many people - including myself - resonate with both frames. But I have a **general fear that the “competition” frame is going to be overrated by default** for a number of reasons, as I discuss [here](https://forum.effectivealtruism.org/s/isENJuPdB3fhjWYHd/p/Lbtcjfxhrs8kfKK2M#Why_I_fear__competition__being_overrated__relative_to__caution_).
Unfortunately, I’ve seen something like the above story play out in **multiple significant instances** (though I shouldn’t give specific examples).
And I’m especially worried about this dynamic when it comes to people in and around governments (especially in national security communities)*,* because I perceive governmental culture as particularly obsessed with *staying ahead of other countries* (“If AI is dangerous, we’ve gotta build it first”) and comparatively uninterested in *things that are dangerous for our country because they’re dangerous for the whole world at once* (“Maybe we should worry a lot about pandemics?”)
[[1]](#fn1)
You could even [argue](https://twitter.com/michael_nielsen/status/1350544365198839808) (although I wouldn’t agree![[2]](#fn2) that to date, efforts to “raise awareness” about the dangers of AI have done more harm than good (via causing increased investment in AI, generally).
So it’s tempting to simply give up on the whole endeavor - to stay away from message spreading entirely, beyond people you know well and/or are pretty sure will internalize the important details. But I think we can do better.
This post is aimed at people who are **good at communicating** with at least some audience. This could be because of their skills, or their relationships, or some combination. In general, I’d expect to have more success with people who hear from you a lot (because they’re your friend, or they follow you on Twitter or Substack, etc.) than with people you reach via some viral blast of memery - but maybe you’re skilled enough to make the latter work too, which would be awesome. I'm asking communicators to hit a high bar: leave people with strong understanding, rather than just getting them to repeat a few sentences about AI risk.
Messages that seem risky to spread in isolation
-----------------------------------------------
First, here are a couple of messages that I’d rather people *didn’t* spread (or at least have mixed feelings about spreading) in isolation, i.e., without serious efforts to include some of the other messages I cover [below](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/CcJsh4JcxEqYDaSte#Messages_that_seem_important_and_helpful__and_right__).
One category is messages that generically emphasize the *importance* and *potential imminence* of powerful AI systems. The reason for this is in the previous section: many people seem to react to these ideas (especially when unaccompanied by some other key ones) with a “We’d better build powerful AI as fast as possible, before others do” attitude. (If you’re curious about why I wrote [The Most Important Century](https://forum.effectivealtruism.org/s/isENJuPdB3fhjWYHd) anyway, see footnote for my thinking.)[[3]](#fn3)
Another category is messages that emphasize that AI could be risky/dangerous to the world, without much effort to fill in *how*, or with an emphasis on easy-to-understand risks.
* Since “dangerous” tends to imply “powerful and important,” I think there are similar risks to the previous section.
* If people have a bad model of *how and why* AI could be risky/dangerous (missing key risks and difficulties), they might be too quick to later say things like “Oh, turns out this danger is less bad than I thought, let’s go full speed ahead!” [Below](https://forum.effectivealtruism.org/posts/CcJsh4JcxEqYDaSte/spreading-messages-to-help-with-the-most-important-century#AIs_could_behave_deceptively__so__evidence_of_safety__might_be_misleading), I outline how misleading “progress” could lead to premature dismissal of the risks.
Messages that seem important and helpful (and right!)
-----------------------------------------------------
### We should worry about conflict between misaligned AI and *all* humans
Unlike the messages discussed in the previous section, this one directly highlights why it might not be a good idea to rush forward with building AI oneself.
The idea that an AI could harm the *same humans who build it* has very different implications from the idea that AI could be generically dangerous/powerful. Less “We’d better get there before others,” more “there’s a case for moving slowly and working together here.”
The idea that AI could be a problem for the same people who build it is common in fictional portrayals of AI ([HAL 9000](https://en.wikipedia.org/wiki/HAL_9000), [Skynet](https://en.wikipedia.org/wiki/Skynet_(Terminator)), [The Matrix](https://en.wikipedia.org/wiki/The_Matrix), [Ex Machina](https://en.wikipedia.org/wiki/Ex_Machina_(film))) - maybe too much so? It seems to me that people tend to balk at the “sci-fi” feel, and what’s needed is more recognition that this is a serious, real-world concern.
The main pieces in this series making this case are [Why would AI “aim” to defeat humanity?](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/vGsRdWzwjrFgCXdMn) and [AI could defeat all of us combined](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/6LTh4foNuC3NdtmZH). There are many other pieces on the alignment problem (see list [here](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/vGsRdWzwjrFgCXdMn#Notes)); also see [Matt Yglesias's case](https://www.slowboring.com/p/the-case-for-terminator-analogies) for specifically embracing the “Terminator”/Skynet analogy.
I’d be especially excited for people to spread messages that help others understand - at a mechanistic level - *how and why* AI systems could end up with dangerous goals of their own, deceptive behavior, etc. I worry that by default, the concern sounds like lazy anthropomorphism (thinking of AIs just like humans).
Transmitting ideas about the “how and why” is a lot harder than getting people to nod along to “AI could be dangerous.” I think there’s a lot of effort that could be put into simple, understandable yet relatable metaphors/analogies/examples (my pieces make some effort in this direction, but there’s tons of room for more).
### AIs could behave deceptively, so “evidence of safety” might be misleading
I’m very worried about a sequence of events like:
* As AI systems become more powerful, there are some concerning incidents, and widespread concern about “AI risk” grows.
* But over time, AI systems are “better trained” - e.g., given reinforcement to stop them from behaving in unintended ways - and so the concerning incidents become less common.
* Because of this, concern dissipates, and it’s widely believed that AI safety has been “solved.”
* But what’s actually happened is that the “better training” has caused AI systems to *behave deceptively* - to *appear* benign in most situations, and to cause trouble only when (a) this wouldn’t be detected or (b) humans can be [overpowered entirely](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/6LTh4foNuC3NdtmZH).
I worry about AI systems’ being deceptive in the same way a human might: going through chains of reasoning like “If I do X, I might get caught, but if I do Y, no one will notice until it’s too late.” But it can be hard to get this concern taken seriously, because it means attributing behavior to AI systems that we currently associate exclusively with humans (today’s AI systems don’t really do things like this[[4]](#fn4).
One of the central things I’ve tried to spell out in this series is *why* an AI system might engage in this sort of systematic deception, despite being very unlike humans (and not necessarily having e.g. emotions). It’s a major focus of both of these pieces from this series:
* [Why would AI “aim” to defeat humanity?](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/vGsRdWzwjrFgCXdMn)
* [AI Safety Seems Hard to Measure](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/NbiHKTN5QhFFfjjm5)
Whether this point is widely understood seems quite crucial to me. We might end up in a situation where (a) there are big commercial and military incentives to rush ahead with AI development; (b) we have what *seems like* a set of reassuring experiments and observations.
At that point, it could be key whether people are asking tough questions about the many ways in which “evidence of AI safety” could be misleading, which I discussed at length in [AI Safety Seems Hard to Measure](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/NbiHKTN5QhFFfjjm5).
(Click to expand) Why AI safety could be hard to measure
In previous pieces, I argued that:
* If we develop powerful AIs via ambitious use of the “black-box trial-and-error” common in AI development today, then there’s a substantial risk that:
+ These AIs will develop [unintended aims](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/vGsRdWzwjrFgCXdMn) (states of the world they make calculations and plans toward, as a chess-playing AI "aims" for checkmate);
+ These AIs could deceive, manipulate, and even [take over the world from humans entirely](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/6LTh4foNuC3NdtmZH) as needed to achieve those aims.
+ People today are doing AI safety research to prevent this outcome, but such research has a [number of deep difficulties:](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/NbiHKTN5QhFFfjjm5)

| **“Great news - I’ve tested this AI and it looks safe.”** Why might we still have a problem?
|
| *Problem* | *Key question* | *Explanation* |
| The **Lance Armstrong problem** | Did we get the AI to be **actually safe** or **good at hiding its dangerous actions?** | When dealing with an intelligent agent, it’s hard to tell the difference between “behaving well” and “*appearing* to behave well.”
When professional cycling was cracking down on performance-enhancing drugs, Lance Armstrong was very successful and seemed to be unusually “clean.” It later came out that he had been using drugs with an unusually sophisticated operation for concealing them.
|
| The **King Lear problem** | The AI is **(actually) well-behaved when humans are in control.** Will this transfer to **when AIs are in control?** | It's hard to know how someone will behave when they have power over you, based only on observing how they behave when they don't.
AIs might behave as intended as long as humans are in control - but at some future point, AI systems might be capable and widespread enough to have opportunities to [take control of the world entirely](https://forum.effectivealtruism.org/posts/6LTh4foNuC3NdtmZH/ai-could-defeat-all-of-us-combined). It's hard to know whether they'll take these opportunities, and we can't exactly run a clean test of the situation.
Like King Lear trying to decide how much power to give each of his daughters before abdicating the throne.
|
| The **lab mice problem** | **Today's "subhuman" AIs are safe.**What about **future AIs with more human-like abilities?** | Today's AI systems aren't advanced enough to exhibit the basic behaviors we want to study, such as deceiving and manipulating humans.
Like trying to study medicine in humans by experimenting only on lab mice.
|
| The **first contact problem** | Imagine that **tomorrow's "human-like" AIs are safe.** How will things go **when AIs have capabilities far beyond humans'?** | AI systems might (collectively) become vastly more capable than humans, and it's ... just really hard to have any idea what that's going to be like. As far as we know, there has never before been anything in the galaxy that's vastly more capable than humans in the relevant ways! No matter what we come up with to solve the first three problems, we can't be too confident that it'll keep working if AI advances (or just proliferates) a lot more.
Like trying to plan for first contact with extraterrestrials (this barely feels like an analogy).

### AI projects should establish and demonstrate safety (and potentially comply with safety standards) before deploying powerful systems
I’ve [written about](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/XRphCh6NbfQiDF3Nt#Global_monitoring__noticing_people_about_to_step_on_mines__and_stopping_them_) the benefits we might get from “safety standards." The idea is that AI projects should not deploy systems that pose too much risk to the world, as evaluated by a systematic evaluation regime: AI systems could be audited to see whether they are safe. I've outlined how AI projects might self-regulate by publicly committing to having their systems audited (and not deploying dangerous ones), and how governments could enforce safety standards both nationally and internationally.
Today, development of safety standards is in its infancy. But over time, I think it could matter a lot how much pressure AI projects are under to meet safety standards. And I think it’s not too early, today, to start spreading the message that **AI projects shouldn’t unilaterally decide to put potentially dangerous systems out in the world; the burden should be on them to demonstrate and establish safety before doing so.**
(Click to expand) How standards might be established and become national or international
I [previously](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/XRphCh6NbfQiDF3Nt#Global_monitoring__noticing_people_about_to_step_on_mines__and_stopping_them_) laid out a possible vision on this front, which I’ll give a slightly modified version of here:
* Today’s leading AI companies could self-regulate by committing not to build or deploy a system that they can’t convincingly demonstrate is safe (e.g., see Google’s [2018 statement](https://www.theweek.in/news/sci-tech/2018/06/08/google-wont-deploy-ai-to-build-military-weapons-ichai.html), "We will not design or deploy AI in weapons or other technologies whose principal purpose or implementation is to cause or directly facilitate injury to people”).
+ Even if some people at the companies would like to deploy unsafe systems, it could be hard to pull this off once the company has committed not to.
+ Even if there’s a lot of room for judgment in what it means to demonstrate an AI system is safe, having agreed in advance that [certain evidence](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/CcJsh4JcxEqYDaSte#AIs_could_behave_deceptively__so__evidence_of_safety__might_be_misleading) is *not* good enough could go a long way.
* As more AI companies are started, they could feel soft pressure to do similar self-regulation, and refusing to do so is off-putting to potential employees, investors, etc.
* Eventually, similar principles could be incorporated into various government regulations and enforceable treaties.
* Governments could monitor for dangerous projects using regulation and even overseas operations. E.g., today the US monitors (without permission) for various signs that other states might be developing nuclear weapons, and might try to stop such development with methods ranging from threats of sanctions to [cyberwarfare](https://en.wikipedia.org/wiki/Stuxnet) or even military attacks. It could do something similar for any AI development projects that are using huge amounts of compute and haven’t volunteered information about whether they’re meeting standards.
### Alignment research is prosocial and great
Most people reading this can’t go and become groundbreaking researchers on AI alignment. But they *can* contribute to a general sense that the people who can do this (mostly) should.
Today, my sense is that most “science” jobs are pretty prestigious, and seen as good for society. I have pretty mixed feelings about this:
* I think science has been [good for humanity historically](https://forum.effectivealtruism.org/posts/z7quAxWyHuqFdxGE6/rowing-steering-anchoring-equity-mutiny-1).
* But I worry that as technology becomes more and more powerful, there’s a growing risk of a catastrophe (particularly via AI or bioweapons) that wipes out all the progress to date and then some. (I've [written](https://www.cold-takes.com/has-violence-declined-when-we-include-the-world-wars-and-other-major-atrocities/) that the historical trend to date arguably fits something like "Declining everyday violence, offset by bigger and bigger rare catastrophes.") I think our current era would be a nice time to adopt an attitude of “proceed with caution” rather than “full speed ahead.”
* I resonate with Toby Ord’s comment (in [The Precipice](https://theprecipice.com/)), “humanity is akin to an adolescent, with rapidly developing physical abilities, lagging wisdom and self-control, little thought for its longterm future and an unhealthy appetite for risk.”
I wish there were more effort, generally, to distinguish between especially dangerous science and especially beneficial science. AI alignment seems squarely in the latter category.
I’d be especially excited for people to spread messages that give a sense of the specifics of different AI alignment research paths, how they might help or fail, and what’s scientifically/intellectually interesting (not just useful) about them.
The main relevant piece in this series is [High-level hopes for AI alignment](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/rJRw78oihoT5paFGd), which distills a longer piece ([How might we align transformative AI if it’s developed very soon?](https://forum.effectivealtruism.org/posts/sW6RggfddDrcmM6Aw/how-might-we-align-transformative-ai-if-it-s-developed-very)) that I posted on the Alignment Forum.
There are a number (hopefully growing) of other careers that I consider especially valuable, which I'll discuss in my next post on this topic.
### It might be important for companies (and other institutions) to act in unusual ways
In [Racing through a Minefield: the AI Deployment Problem](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/XRphCh6NbfQiDF3Nt), I wrote:
> **A lot of the most helpful actions might be “out of the ordinary.”** When racing through a minefield, I hope key actors will:

It always makes me sweat when I’m talking to someone from an AI company and they seem to think that commercial success and benefiting humanity are roughly the same goal/idea.
(To be clear, I don't think an AI project's only goal should be to avoid the risk of misaligned AI. I've given this risk a central place in this piece partly because I think it's especially at risk of being too quickly dismissed - but I don't think it's the only major risk. I think AI projects need to strike a tricky balance between the [caution and competition frames](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/CcJsh4JcxEqYDaSte#Challenges_of_AI_related_messages), and consider a number of issues [beyond the risk of misalignment](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/mPkFheB4EM6pmEC7y). But I think it's a pretty robust point that they need to be ready to do unusual things rather than just following commercial incentives.)
I’m nervous about a world in which:
* Most people stick with paradigms they know - a company should focus on shareholder value, a government should focus on its own citizens (rather than global catastrophic risks), etc.
* As the [pace of progress accelerates](https://forum.effectivealtruism.org/s/isENJuPdB3fhjWYHd/p/AmxxnazJcBWzWEeqj#Impacts_of_PASTA), we’re sitting here with all kinds of laws, norms and institutions that aren’t designed for the problems we’re facing - and can’t adapt in time. A good example would be the way [governance](https://forum.effectivealtruism.org/posts/hxTFAetiiSL7dZmyb/ideal-governance-for-companies-countries-and-more) works for a standard company: it’s legally and structurally obligated to be entirely focused on benefiting its shareholders, rather than humanity as a whole. (There are alternative ways of setting up a company without these problems![[5]](#fn5)
At a minimum (as I [argued previously](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/XRphCh6NbfQiDF3Nt)), I think AI companies should be making sure they have whatever unusual governance setups they need in order to prioritize benefits to humanity - not returns to shareholders - when the stakes get high. I think we’d see more of this if more people believed something like: “It might be important for companies (and other institutions) to act in unusual ways.”
### We’re not ready for this
If we’re in the [most important century](https://forum.effectivealtruism.org/s/isENJuPdB3fhjWYHd), there’s likely to be a vast set of potential challenges ahead of us, most of which have gotten very little attention. (More here: [Transformative AI issues (not just misalignment): an overview](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/mPkFheB4EM6pmEC7y))
If it were possible to slow everything down, by default I’d think we should. Barring that, I’d at least like to see people generally approaching the topic of AI with a general attitude along the lines of “We’re dealing with something really big here, and we should be trying really hard to be careful and humble and thoughtful” (as opposed to something like “The science is so interesting, let’s go for it” or “This is awesome, we’re gonna get rich” or “Whatever, who cares”).
I’ll re-excerpt this table from an [earlier piece](https://forum.effectivealtruism.org/s/isENJuPdB3fhjWYHd/p/uNczpTHFvjt4KNxEF#Sharing_a_headspace):
| | |
| --- | --- |
| **Situation** | **Appropriate reaction (IMO)** |
| "This could be a billion-dollar company!"
| "Woohoo, let's GO for it!"
|
| "This could be the most important century!"
| "... Oh ... wow ... I don't know what to say and I somewhat want to vomit ... I have to sit down and think about this one."
|
I’m not at all sure about this, but one potential way to spread this message might be to communicate, with as much scientific realism, detail and believability as possible, about what the world might look like after explosive scientific and technological advancement brought on by AI (for example, a world with [digital people](https://forum.effectivealtruism.org/s/isENJuPdB3fhjWYHd/p/AKxKR4CeakyBsGFoH)). I think the enormous unfamiliarity of some of the [issues](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w/p/mPkFheB4EM6pmEC7y#New_life_forms) such a world might face - and the vast possibilities for [utopia](https://www.cold-takes.com/tag/utopia/) or [dystopia](https://forum.effectivealtruism.org/s/isENJuPdB3fhjWYHd/p/AKxKR4CeakyBsGFoH#Virtual_reality_and_control_of_the_environment) - might encourage an attitude of not wanting to rush forward.
How to spread messages like these?
----------------------------------
I’ve tried to write a [series](https://forum.effectivealtruism.org/s/gBjPorwZHRArNSQ5w) that explains the key issues to careful readers, hopefully better equipping them to spread helpful messages. From here, individual communicators need to think about the audiences they know and the mediums they use (Twitter? Facebook? Essays/newsletters/blog posts? Video? In-person conversation?) and what will be effective with those audiences and mediums.
The main guidelines I want to advocate:
* Err toward sustained, repeated, relationship-based communication as opposed to prioritizing “viral blasts” (unless you are so good at the latter that you feel excited to spread the pretty subtle ideas in this piece that way!)
* Aim high: try for the difficult goal of “My audience walks away really understanding key points” rather than the easier goal of “My audience has hit the ‘like’ button for a sort of related idea.”
* A consistent piece of feedback I’ve gotten on my writing is that making things as concrete as possible is helpful - so giving real-world examples of problems analogous to the ones we’re worried about, or simple analogies that are easy to imagine and remember, could be key. But it’s important to choose these carefully so that the key dynamics aren’t lost.

2. When I imagine what the world would look like without any of the efforts to “raise awareness,” I picture a world with close to zero awareness of - or community around - major risks from transformative AI. While this world might *also* have more *time* left before dangerous AI is developed, on balance this seems worse. A future piece will elaborate on the many ways I think a decent-sized community can help reduce risks. [↩](#fnref2)
3. I do think “AI could be a huge deal, and soon” is a very important point that somewhat serves as a prerequisite for understanding this topic and doing helpful work on it, and I wanted to make this idea more understandable and credible to a number of people - as well as to [create more opportunities to get critical feedback and learn what I was getting wrong](https://forum.effectivealtruism.org/posts/7JxsXYDuqnKMqa6Eq/ai-timelines-where-the-arguments-and-the-experts-stand).
But I was nervous about the issues noted in this section. With that in mind, I did the following things:
* The title, “most important century,” emphasizes a time frame that I expect to be less exciting/motivating for the sorts of people I’m most worried about (compared to the sorts of people I most wanted to draw in).
* I tried to persistently and centrally raise concerns about misaligned AI (raising it in two pieces, including [one (guest piece) devoted to it](https://forum.effectivealtruism.org/s/isENJuPdB3fhjWYHd/p/hCsxvMAGpkEuLCE4E#Powerful_models_could_get_good_performance_with_dangerous_goals), before I started discussing how soon transformative AI might be developed), and [extensively discussed](https://forum.effectivealtruism.org/s/isENJuPdB3fhjWYHd/p/Lbtcjfxhrs8kfKK2M) the problems of overemphasizing “competition” relative to “caution.”
* I [ended the series](https://forum.effectivealtruism.org/s/isENJuPdB3fhjWYHd/p/uNczpTHFvjt4KNxEF) with a piece arguing against being too “action-oriented.”
* I stuck to “passive” rather than “active” promotion of the series, e.g., I accepted podcast invitations but didn’t seek them out. I figured that people with proactive interest would be more likely to give in-depth, attentive treatments rather than low-resolution, oversimplified ones.
I don’t claim to be sure I got all the tradeoffs right. [↩](#fnref3)
4. There are some papers arguing that AI systems do things *something* like this (e.g., see the “Challenges” section of [this post](https://openai.com/blog/deep-reinforcement-learning-from-human-preferences/)), but I think the dynamic is overall pretty far from what I’m most worried about.

Thanks to Evan Hubinger for funding this project and for introducing me to predictive models, Johannes Treutlein for many fruitful discussions on related topics, and Dan Valentine for providing valuable feedback on my code implementation.
In September 2023, I received four months of funding through Manifund to extend my initial results on avoiding self-fulfilling prophecies in predictive models. Eleven months later, the project was finished, and the results were submitted as a conference paper.
The project was largely successful, in that it showed both theoretically and experimentally how incentives for predictive accuracy can be structed so that maximizing them does not manipulate outcomes to be more predictable. The mechanism at play is essentially pitting predictive agents against each other in a zero-sum competition, which allows for the circumvention of impossibility results in the single agent case. While there was one notable result that eluded me, related to the case where agents each have private information, I still think meaningful progress has been made towards defining a goal which is both safe to optimize for and useful enough to enable a pivotal act.
This post contains similar content to the submitted paper, but in a framing more directly addressed to readers who are already informed and interested in alignment. There are also several results here that were cut from the paper version for space, and slightly less formal notation. Overall, I would recommend reading this post over the paper itself.
Predictive Agents and Performative Prediction
In a previous post, I summarized the case for investigating predictive models, largely using points from the Conditioning Predictive Models paper. The gist of the argument, which you can click through to read in full, is that predictive models are potentially useful enough to be used to take a pivotal act, easier to align than general agents, and coming anyway.

Note: This post is part of my series of posts on forecasting, but this particular post may be of fairly limited interest to many LessWrong readers. I'm posting it here mainly for completeness. As always, I appreciate feedback.
In the course of my work looking at forecasting for MIRI, I repeatedly encountered discussions of how to communicate forecasts. In particular, a concern that emerged repeatedly was the clear communication of the uncertainty in forecasts. Nate Silver's The Signal and the Noise, in particular, focused quite a bit on the virtue of clear communication of uncertainty, in contexts as diverse as financial crises, epidemiology, weather forecasting, and climate change.
In this post, I pull together discussions from a variety of domains about the communication of uncertainty, and also included my overall impression of the findings.
Summary of overall findings
* In cases where forecasts are made and used frequently (the most salient example being temperature and precipitation forecasts) people tend to form their own models of the uncertainty surrounding forecasts, even if you present forecasts as point estimates. The models people develop are quite similar to the correct ones, but still different in important ways.
* In cases where forecasts are made more rarely, as with forecasting rare events, people are more likely to have simpler models that acknowledge some uncertainty but are less nuanced. In these cases, acknowledging uncertainty becomes quite important, because wrong forecasts of such events can lead to a loss of trust in the forecasting process, and can lead people to ignore correct forecasts later.
* In some cases, there are arguments for modestly exaggerating small probabilities to overcome specific biases that people have that cause them to ignore low-probability events.
* However, the balance of evidence suggests that forecasts should be reported as honestly as possible, and all uncertainty should be clearly acknowledged. If the for |

This collection of exercises is supplementary material for our [mathematical framework](https://transformer-circuits.pub/2021/framework/index.html) for reverse engineering transformers. The exercises go through writing down individual weights for attention heads, in order to implement algorithms. We've found this helpful in developing our own understanding, as a way to make sure we really understand the full mechanistic story of transformers all the way down to individual parameters, and not blurring over any confusions.
Solutions are provided [below](#solutions).

Exercises
---------
#### Warm Up
* Describe the transformer architecture at a high level
* Describe how an individual attention head works in detail, in terms of the matrices W\_Q, W\_K, W\_V, and W\_{out}. (The equations and code for an attention head are often written for all attention heads in a layer concatenated together at once. This implementation is more computationally efficient, but harder to reason about, so we'd like to describe a single attention head.)
* Attention heads move information from a subspace of the residual stream of one token to a different subspace in the residual stream of another. Which matrix controls the subspace that gets read, and which matrix controls the subspace written to? What does their product mean?
* Which tokens an attention head attends to is controlled by only two of the four matrices that define an attention head. Which two matrices are these?
* Attention heads can be written in terms of two matrices instead of four, W\_Q^T \cdot W\_k and W\_{out} \cdot W\_v. In the previous two questions, you gave interpretations to these matrices. Now write out an attention head with only reference to them.
* What is the rank of these matrices?
* You'd like to understand whether an attention head is reading in the output of a previous attention head. What does W\_V^2 \cdot W\_{out}^1 tell you about this? What do the singular values tell you?
#### Exercise 1 - Building a simple virtual attention head
Small transformers often have multiple attention heads which look at the previous token, but no attention heads which look at the token two previous. In this exercise, we'll see how two previous token heads can implement a small "virtual attention head" looking two tokens behind, without sacrificing a full attention head to the purpose.
Let's consider two attention heads, head 1 and head 2, which both attend to the previous token. Head 1 is in the first layer, head 2 is in the second layer. To make it easy to write out explicit matrices, we'll have the k, q, and v vectors of both heads be 4 dimensions and the residual stream be 16 dimensions.
* (a) Write down W\_V^1 and W\_{out}^1 for head 1, such that the head copies dimensions 0-3 of its input to 8-11 in its output.
* (b) Write down W\_V^2 and W\_{out}^2 for head 2, such that it copies 3 more dimensions of the previous token, and one dimension from two tokens ago (using a dimension written to by the previous head).
* (c) Expand out W\_{\text{net}}^1 = W\_{out}^1 \cdot W\_V^1 and W\_{\text{net}}^2 = W\_{out}^2 \cdot W\_V^2. What do these matrices tell you?
* (d) Expand out the following matrices: Two token copy: W\_{\text{net}}^2 \cdot W\_{\text{net}}^1. One token copy: W\_{\text{net}}^2 \cdot \text{Id} ~+~ \text{Id} \cdot W\_{\text{net}}^1.
* Observation: When we think of an attention head normally, they need to dedicate all their capacity to one task. In this case, the two heads dedicated 7/8ths of their capacity to one task and 1/8th to another.
#### Exercise 2 - Copying Text with an Induction Head (Pointer Arithmetic Version)
The simplest kind of in-context meta-learning that neural networks do is increasing the probability of sequences they've seen before in this context. This is done with an "induction head" that looks at what followed after last time we saw a token.
There are at least two algorithms for implementing induction heads. In this exercise, you'll build up the "pointer arithmetic" algorithm by hand.
* (a) Let u^{\text{cont}}\_0, ~~ u^{\text{cont}}\_1, ~~ \ldots ~~ u^{\text{cont}}\_n be the principal components of the content embedding. Write W\_Q and W\_K for an attention head (with 4 dimensional queries and keys) selecting tokens with similar content to the present token, including the present token itself.
* (b) Let u^{\cos}\_0, ~ u^{\sin}\_0, ~ u^{\cos}\_1, ~ u^{\sin}\_1, ~ ... be a basis describing the position embedding in terms of vectors that code for the sine and cosine embedding of the token position (eg. \lambda\cos(\alpha\_0 n\_{tok})) with descending magnitudes. Write W\_Q and W\_K for an attention head (with 4 dimensional queries and keys) that self-selects the present token position.
* (c) Using the position embedding basis described in (b), write W\_Q and W\_K for an attention head (with 4 dimensional queries and keys) that self-selects the \*previous\* token position. Hint: think about a 2D rotation matrix.
* (d) Write W\_Q and W\_K for an attention head (with 8 dimensional queries and keys) selecting tokens with similar content to the present token, but disprefers attending to itself. Hint: refer to (b) and use extra 4 dimensions for keys and queries.
* (e) Write down W\_V and W\_{out} for the attention head you described in (d), such that it extracts the largest 8 dimensions of the position embedding from the token it attends to, and writes them to the vectors v\_0, v\_1, ....
* (f) Write W\_Q and W\_K for an attention head which attends to the token after a previous copy of the present token. Hint: use the outputs of the head from (e) and the strategy you used in (c).
#### Exercise 3 - Copying Text with an Induction Head (Previous Token K-Composition Version)
Some positional encoding mechanisms, such as rotary attention, don't expose positional information to the W\_V matmul. Transformers trained with these mechanisms can't use the strategy from (e) and (f) in the previous exercise to manipulate positional encoding vectors.
For these transformers, we've seen an alternate mechanism, where the first head copies information about the preceding token into a subspace, and the second head uses that subspace to construct queries and keys. Assuming the same positional encoding mechanism as above, write down W^1\_Q, W^1\_K, W^1\_V, W^1\_O and W^2\_Q and W^2\_K for a pair of attention heads implementing this algorithm.

Solutions
---------
#### Warmup
See our [paper on transformer ciruits](https://transformer-circuits.pub/2021/framework/index.html) for discussion of all of these questions.
#### Exercise 1 - Building a simple virtual attention head
(1)(a) Write down W\_V^1 and W\_{out}^1 for head 1, such that the head copies dimensions 0-3 of its input to 8-11 in its output.

(1)(b) Write down W\_V^2 and W\_{out}^2 for head 2, such that it copies 3 more dimensions of the previous token, and one dimension from two tokens ago (using a dimension written to by the previous head).
Note that there are many correct answers here. The primary important property is that W\_V^2 has one 1 in a column corresponding to a row of W\_O^1, and three 1s in columns which are untouched by W\_V^1 and W\_O^1.

(1)(c) Expand out W\_{\text{net}}^1 = W\_{out}^1 \cdot W\_V^1 and W\_{\text{net}}^2 = W\_{out}^2 \cdot W\_V^2. What do these matrices tell you?

These matrices describe the full operation of an attention head when moving information from the residual stream at one position (which is attended to) to another:
h\_i(x) = \sum\_j A\_{ij}W\_{net}x\_{j}
(1)(d) Expand out the following matrices: Two token copy: W\_{\text{net}}^2 \cdot W\_{\text{net}}^1. One token copy: W\_{\text{net}}^2 \cdot \text{Id} ~+~ \text{Id} \cdot W\_{\text{net}}^1.

#### Exercise 2 - Copying Text with an Induction Head (Pointer Arithmetic Version)
(2)(a) Let u^{\text{cont}}\_0, ~~ u^{\text{cont}}\_1, ~~ \ldots ~~ u^{\text{cont}}\_n be the principal components of the content embedding. Write W\_Q and W\_K for an attention head (with 4 dimensional queries and keys) selecting tokens with similar content to the present token, including the present token itself.
W\_Q = W\_K = \begin{pmatrix}u\_0^{cont} \\u\_1^{cont} \\u\_2^{cont} \\u\_3^{cont} \end{pmatrix}
We simply project the content dimensions into both heads. Note that, in this example and all that follow, we could compose an arbitrary rotation into both matrices and arrive at a functionally equivalent head. We show what we consider to be the most straightforward version of these matrices.
(2)(b) Let u^{\cos}\_0, ~ u^{\sin}\_0, ~ u^{\cos}\_1, ~ u^{\sin}\_1, ~ ... be a basis describing the position embedding in terms of vectors that code for the sine and cosine embedding of the token position (eg. \lambda\cos(\alpha\_0 n\_{tok})) with descending magnitudes. Write W\_Q and W\_K for an attention head (with 4 dimensional queries and keys) that self-selects the present token position.
W\_Q = W\_K = \begin{pmatrix} u\_0^{cos} \\ u\_0^{sin} \\ u\_1^{cos} \\ u\_1^{sin} \end{pmatrix}
(2)(c) Using the position embedding basis described in (b), write W\_Q and W\_K for an attention head (with 4 dimensional queries and keys) that self-selects the \*previous\* token position. Hint: think about a 2D rotation matrix.
Note that by the definition of u^{\cos}\_0, ~ u^{\sin}\_0, … is that they encode the token index n as a cosine or sine wave. If we think of the corresponding cosine and sine pair together, we can think of it as a two dimensional point:
(u\_0^{\cos}, ~u\_0^{\sin})\cdot x^0\_n ~=~ \lambda\_0(\cos(\alpha\_0n),~ \sin(\alpha\_0n))
If we do the same thing for the token n-1, we find that it is the point for token n rotated by -\alpha\_0:
\begin{aligned} (u\_0^{\cos}, u\_0^{\sin}) \cdot x^0\_{n-1} &~=~ \lambda\_0(\cos(\alpha\_0(n-1)),~ \sin(\alpha\_0(n-1))) \\ &~=~ \lambda\_0(\cos(\alpha\_0n-\alpha\_0),~ \sin(\alpha\_0n-\alpha\_0))\\ &~=~ \lambda\_0R\_{-\alpha\_0}(\cos(\alpha\_0n),~ \sin(\alpha\_0n) \end{aligned}
So we want to take the positional embedding vectors, pair up the sin and cosine components, and perform a 2d rotation. A 2d rotation about the origin is:
R\_\theta=\begin{pmatrix} \cos\theta & -\sin\theta \\ \sin\theta & \cos\theta \end{pmatrix}
We compose two such rotations along with a projection of the positional basis, to arrive at:
W\_K = \textrm{(as part (b))}
W\_Q = \begin{pmatrix} \cos\alpha\_0 & \sin\alpha\_0 & & \\-\sin\alpha\_0 & \cos\alpha\_0 & & \\& & \cos\alpha\_1 & \sin\alpha\_1 \\& & -\sin\alpha\_1 & \cos\alpha\_1 \end{pmatrix} \begin{pmatrix} u\_0^{cos} \\ u\_0^{sin} \\ u\_1^{cos} \\ u\_1^{sin} \end{pmatrix}
(2)(d) Write W\_Q and W\_K for an attention head (with 8 dimensional queries and keys) selecting tokens with similar content to the present token, but disprefers attending to itself. Hint: refer to (b) and use extra 4 dimensions for keys and queries.
W\_K=\begin{pmatrix} u\_0^{cont} \\ u\_1^{cont} \\ u\_2^{cont} \\ u\_3^{cont} \\ u\_0^{cos} \\ u\_0^{sin} \\ u\_1^{cos} \\ u\_1^{sin} \end{pmatrix} ~~~~W\_Q=\begin{pmatrix} u\_0^{cont} \\ u\_1^{cont} \\ u\_2^{cont} \\ u\_3^{cont} \\ -\beta{}u\_0^{cos} \\ -\beta{}u\_0^{sin} \\ -\beta{}u\_1^{cos} \\ -\beta{}u\_1^{sin} \end{pmatrix}
\beta is a parameter that lets us tune the relative weight of the “same token” and “not the present position” parts of the computation.
(2)(e) Write down W\_V and W\_{out} for the attention head you described in (d), such that it extracts the largest 8 dimensions of the position embedding from the token it attends to, and writes them to the vectors v\_0, v\_1, ....
W\_V=\begin{pmatrix} u\_0^{cos} \\ u\_0^{sin} \\ u\_1^{cos} \\ u\_1^{sin} \\ u\_2^{cos} \\ u\_2^{sin} \\ u\_3^{cos} \\ u\_3^{sin} \end{pmatrix} ~~~~W\_O = \begin{pmatrix}v\_0^T&v\_1^T&v\_2^T&\ldots{}\end{pmatrix}
(2)(f) Write W\_Q and W\_K for an attention head which attends to the token after a previous copy of the present token. Hint: use the outputs of the head from (e) and the strategy you used in (c).
The head described in (d) and (e) puts “the position of the previous instance of this token” into the subspace defined by v\_0, v\_1, \ldots{}. We project that subspace out, and rotate it the same way as (c), except forwards instead of backwards:
W\_K = \begin{pmatrix}u\_0^{cos} \\ u\_0^{sin} \\ u\_1^{cos} \\ u\_1^{sin}\end{pmatrix} ~~~~ W\_Q = \begin{pmatrix} \cos\alpha\_0 & -\sin\alpha\_0 & & \\ \sin\alpha\_0 & \cos\alpha\_0 & & \\ & & \cos\alpha\_1 & -\sin\alpha\_1 \\ & & \sin\alpha\_1 & \cos\alpha\_1 \end{pmatrix} \begin{pmatrix} v\_0\\ v\_1\\ v\_2\\ v\_3 \end{pmatrix}
#### Exercise 3 - Copying Text with an Induction Head (Previous Token K-Composition Version)
The first head copies the “content” subspace of the previous token into the v\_0, v\_1, \ldots{} subspace of the present position:
W\_K = \begin{pmatrix}u\_0^{cos} \\ u\_0^{sin} \\ u\_1^{cos} \\ u\_1^{sin}\end{pmatrix} ~~~~ W\_Q = \begin{pmatrix} \cos\alpha\_0 & \sin\alpha\_0 & & \\ -\sin\alpha\_0 & \cos\alpha\_0 & & \\ & & \cos\alpha\_1 & \sin\alpha\_1 \\ & & -\sin\alpha\_1 & \cos\alpha\_1 \end{pmatrix} \begin{pmatrix}u\_0^{cos} \\ u\_0^{sin} \\ u\_1^{cos} \\ u\_1^{sin}\end{pmatrix}
W\_V = \begin{pmatrix} u\_0^{cont} \\ u\_1^{cont} \\ u\_2^{cont} \\ u\_3^{cont} \end{pmatrix} ~~~~ W\_O = \begin{pmatrix}v\_0^T&v\_1^T&v\_2^T&\ldots{}\end{pmatrix}
The second head can then use that subspace in its key projection, and compare it to the current token’s content:
W\_K = \begin{pmatrix}v\_0\\v\_1\\v\_2\\v\_3\end{pmatrix} ~~~~W\_Q = \begin{pmatrix} u\_0^{cont} \\ u\_1^{cont} \\ u\_2^{cont} \\ u\_3^{cont} \end{pmatrix} |

The purpose of this post is to briefly talk about two categories of alignment and how I think AI safety evaluations should use them. I only consider responsible deployment in 20XX because I often find discussions about 2XXX to be distracting and unproductive. Also, for the remainder of the post, I will only be talking about LLMs, since these could be the 'operating systems' of future AI's (Ex. HuggingGPT). In the near future, LLMs have the highest potential for abuse, and they will be the focus here.
As Connor Leahy and possibly others say, we should be optimistic for the sole reason that we get to build the AIs of the future. A more realistic version of this quote is: we should be optimistic about building our own AI, while acknowledging that others get to build their own AI. This adjustment is made to bring light to the fact that without standardization of safety practices, different groups will have potentially unsound or unknown safety practices.
Safety standardization in AI is challenging due to the lack of comprehensive safety tools, but I want to outline potential industry standards for my own edification. This will be a reminder of the safe practices that I will advocate for during my career.
Mandatory Alignment Evaluations!
--------------------------------
Alignment evaluations should be mandatory for all models after GPT-4 and should be conducted by third-party and in-house groups. It will not be enough if AI companies are relied on to *graciously* open their doors to the [Alignment Research Center](https://www.alignment.org) (ARC). By sheer chance the OpenAI executives had the integrity to have GPT-4 be tested for self-replication and resource acquisition. While the openness is a great present state, my concerns lie with AI capital owners of the near future and the absence of concrete safety obligations, standards and regulations.
The case for oversight and regulation is difficult to make in the United States, but it's an important one. The main crux of the argument for regulation is the classification of generated content as a commercial and industrial product. This definition informs an intuition for the regulation of generated content on the same basis as any influential product massively distributed to the public sphere and private sectors (i.e. food stuff, fabric, children's toys, cyber security etc.). I plan on making a post about that in the future and when I do it will be linked here.
Instead of justifying a legal basis for regulation, in this post I will talk about two classes of alignment evaluation. I think these two classes are broad enough to hold up in the future however, like most things, techniques in practice will/should be a combination of many tricks.
### Static Alignment
Static alignment is when evaluators unleash algorithms onto the weights of a model and look for specific structures. Since looking at weights does not require running the model, this is the safest type of alignment evaluation. Currently there is no ability for static evaluation but hopefully these will emerge from a field like Mechanistic Interpretability.
In its best form this type of analysis will look at weights through some lens and identify inner structures that can be manipulated to massively change or control model behavior. If this is possible then it is also possible to study the way that these structures form during training as well as how that formation relates to training data.
In its lesser form, static alignment in large models will prove to be a Sisyphean act of looking for inner structures in model N and hoping that they generalize to model N + 1. If we are unable to build robust static analysis tools, by the time model N + 1 arrives we will have failed to detect some percent of the danger, and this missed danger will compound as N increases.
Despite the previous paragraph, I am optimistic because of work being done by Mechanistic Interpretability researchers like [Neel Nanda](https://www.neelnanda.io). He has a [three part series](https://www.youtube.com/watch?v=ob4vuiqG2Go&t=24s) talking about how he reverse-engineered an impressively complex algorithm that a single layer transformer model learned to perform modular addition. This series is an example of how, although the algorithms implemented by LLMs are not designed to be human readable, these algorithms can be understood through rigorous research and mathematical understanding.
### Dynamic Alignment
Dynamic alignment is a class of evaluations that a third-party organization like ARC should be required to conduct. This type of testing usually consists of giving a model limited power and resources and seeing how it behaves. Another type of testing could look at how a model performs competing with itself. Both of these evaluation types prepare for various takeoff scenarios.
One type of dangerous takeoff scenario is when a super intelligent AI is acting in the world untethered. This would have unknown consequences for the world's economy, public trust and international relations. Dynamic evaluation seeks to identify models that, if given the ability to act untethered, pose a risk to humanity. What would we do if we found an AI able to fail a dynamic evaluation? Who knows, but I hope we would not release it and study every facet of its internals. While it is important to decide what we will do if a model fails an ARC evaluation, we should instead focus on increasing the scope of the evaluation set and making each more robust.
Another dangerous takeoff scenario is when a sufficiently dangerous model is irresponsibly released to the public (I'm looking at you Meta...) and the world's leading evil-doers are given a tool powerful enough to cripple a nation. If the models are instead only powerful enough to topple things smaller than nations, then it is likely that the world will have to function with super intelligent agents with conflicting goals. These models, which simulate some kind of agency, will be competing or even collaborating with one another. This type of behavior should be studied and that is why I consider it as a type of evaluation ARC should look into for GPT-5+ and its competitors.
This type of evaluation is notably dangerous since you are giving resources to an under-studied force. We also run into two classic problems. One problem is that a model smart enough to take over the world is likely smart enough to pass a dynamic evaluation. The other problem is that a model smart enough to take over the world is likely smart enough to break out of whichever box we put it in. The problems of deception and self-jail breaking are beyond the scope of this post, so I will not delve deeper.
### Static and Dynamic Alignment in Conjunction
Responsible deployment will involve both types of alignment but the order in which the evaluations are conducted matters. Safety is maximized when static evaluations are done before dynamic evaluations as opposed to the other way around. This should be obvious from a research and scientific lens since static analysis looks for states in the model that will inform the dynamic evaluations. Although running a model will be required to verify claims made by static analysis, the research to verify theories will hopefully be done in less risky scenarios.
The Standard Process
--------------------
The standards in a world with responsible scientists is one where the static model analysis is done before any risky evaluations. Any standard will require thorough research in fields like mechanistic interpretability and deep learning theory. If looking at the weights of a model gives us no knowledge of its behavior, then we will not detect an evil model before we run it. Without robust theories and tools for static model analysis we are doomed to continue to just run gold-spitting black boxes until the end. |

WHERE: MIT Chapel 50 Massachusetts Ave, Cambridge, Massachusetts 02139
It has become tradition, in the community of those who seek to become more rational, to gather for one night of each year, and sing. We do this close to the winter solstice, which is the longest, darkest night of the year; and, gathered as a community, we stare into and confront the darkness. This consists of participatory singing and a few short speeches, following an emotional arc from light to darkness and back to light again. It will last about two hours, starting at 8pm at MIT Chapel at 50 Massachusetts Ave, Cambridge, Massachusetts 02139 and be followed by a reception/afterparty nearby in room 1-132. We may also be organizing an optional pre-ritual potluck nearby, details TBD.

Columbia EA is starting an Advanced AI Safety Fellowship this summer, which will involve one 3-hour meeting per week with a group of people seriously considering careers in AI safety who have some background in both ML (at least working knowledge of linear algebra, multivariable calculus, probability and stats, and neural networks) and AI safety (usually the Cambridge AGI Safety Fundamentals program or a similar reading group we run at Columbia). Each meeting will involve reading about a topic selected the previous week and discussing it, and may also include exercises (like these). While we do not have capacity to invite people from elsewhere to join our meetings, we would like to invite others to follow along with our exploration of the field! You can find our running meeting notes here, where we will write down our meeting agendas, readings, and other notes (maybe key takeaways, responses to exercises, questions, etc.).
The hope is that this can serve as a small, easy win, by motivating at least a few people to set aside time to dive deep into AI alignment topics with little additional effort on our part. Participating in an alternative program with a similar premise, in which the organizers put more effort into making it a good experience for you, would likely be better than following along with us. If such a program already exists, please let me know! I’m not currently aware of any programs that satisfy all of the following properties:
1. Have the basic premise of being a deep dive into AI safety for people with some background in ML and AI safety who are seriously considering careers in the field
2. Are open to anyone with that background
3. Have organizers dedicated to making this a good experience for many interested people from various places
Given that we are not satisfying 3, you could dispense with “following along” and just structure your entire plan yourself if you feel that would work better for you. There are two main benefits we hope to provid |

1. Introduction
----------------
There is a growing community of researchers focused on ensuring that advances in AI are safe and beneficial for humanity (which we call the AI ethics and society community, or AI E&S for short.) The AI E&S research space is very broad, encompassing many different questions: from how AI is likely to impact society in practice to what ethical issues that might raise, and what technical and governance solutions might be needed. These questions are approached from many different perspectives and disciplines: philosophy, computer science, political science, sociology, law, economics, and international relations to name just a few. This research space is fast growing, with new initiatives, workshops, and research centres emerging every year.
Finding ways to break down this broad and evolving research space is important, as it helps researchers to clearly formulate and communicate problems and research agendas, collaborate effectively with others, and to identify gaps in current research. Natural ways to break down the AI E&S research space include by themes or sectors (such as the impact of AI on medicine, the military, or issues of social justice) or in relation to pre-existing disciplines (distinguishing research on ethics from technical approaches from governance and policy, for example).
Due to the cross-cutting nature of AI’s impacts, and the need for deep interdisciplinary collaboration in this space, it may be useful to have ways of carving up the research space that relate to more fundamental priorities and assumptions rather than being tied to specific domains or disciplines. One such way of carving up the research space which has emerged in recent years is to distinguish between those who focus on ‘near-term’ and ‘long-term’ issues (Brundage, [2017](#bib.bib34 "Guide to working in AI policy and strategy"); Cave and ÓhÉigeartaigh, [2019](#bib.bib35 "Bridging near- and long-term concerns about AI"); Krakovna, [2018](#bib.bib32 "Is There a Trade-Off Between Immediate and Longer-term AI Safety Efforts?"); Parson et al., [2019](#bib.bib33 "Artificial Intelligence in Strategic Context: An Introduction")).
However, the distinction between ‘near-term’ and ‘long-term’ is being over-emphasised as a way of characterising differences in the research space. On closer inspection, the distinction is poorly defined, and is used differently across people and contexts: sometimes to refer to issues on different timescales; sometimes to issues related to different types of AI capabilities, and other times masks deeper normative and empirical disagreements. Highlighting inconsistencies in how the near/long-term distinction is used, we argue that it fails to adequately capture the complexity and nuance of different approaches and priorities in the AI E&S research space, and risks causing confusion and fuelling conflict.
By unpacking the distinction between near- and long-term into four different dimensions, we propose some ways to more clearly conceptualise different priorities and disagreements within the AI E&S research space. First, we distinguish between research which focuses on near/long-term capabilities as opposed to near/long-term impacts, and argue that in both cases near/long-term is a spectrum rather than a binary distinction. We show how this way of thinking about different approaches could both improve collaboration and communication between researchers as well as helping to identify important areas of research which are currently neglected. Second, we analyse some of the beliefs and disagreements which seem to underpin differing research priorities, and suggest that clarifying these beliefs could aid mutual understanding between different researchers and groups.
2. The near/long-term distinction in practice
----------------------------------------------
The distinction between near- and long-term in AI E&S is used both to distinguish different types of issues one might be concerned about, as well as to highlight a divide or disagreement between two research communities. In this section, we briefly review how the distinction is made in the literature.
###
2.1. ‘Near-term’ issues
As the phrase ‘near-term’ suggests, those who have written about the distinction tend to characterise near-term issues as those issues that society is already facing or likely to face very soon: Brundage (Brundage, [2017](#bib.bib34 "Guide to working in AI policy and strategy")) defines near-term issues as those society is “grappling with today” and Cave and ÓhÉigeartaigh (Cave and ÓhÉigeartaigh, [2019](#bib.bib35 "Bridging near- and long-term concerns about AI")) talk in terms of “immediate or imminent challenges” (p.5). Examples include concerns about data privacy (Tucker, [2018](#bib.bib3 "Privacy, algorithms, and artificial intelligence"); Zuboff, [2019](#bib.bib4 "The age of surveillance capitalism: the fight for a human future at the new frontier of power")), algorithmic bias (Hajian et al., [2016](#bib.bib5 "Algorithmic bias: from discrimination discovery to fairness-aware data mining"); Koene, [2017](#bib.bib7 "Algorithmic bias: addressing growing concerns [leading edge]")), self-driving car accidents (Goodall, [2016](#bib.bib6 "Can you program ethics into a self-driving car?"); Bonnefon et al., [2016](#bib.bib8 "The social dilemma of autonomous vehicles")), and ethical issues associated with autonomous weapons (Asaro, [2012](#bib.bib9 "On banning autonomous weapon systems: human rights, automation, and the dehumanization of lethal decision-making"); Anderson and Waxman, [2013](#bib.bib10 "Law and ethics for autonomous weapon systems: why a ban won’t work and how the laws of war can")). It is worth noting two things about these examples. First, they tend to be relatively concrete and specific, and an important feature of ‘near-term’ issues is the fact that they are already fairly well-understood. Second, these examples tend to be directly related to recent progress in machine learning which have enabled increasing real-world applications of narrow and specialised AI systems: for example in medical diagnosis and predictive policing (Buch et al., [2018](#bib.bib28 "Artificial intelligence in medicine: current trends and future possibilities"); Richardson et al., [2019](#bib.bib30 "Dirty Data, Bad Predictions: How Civil Rights Violations Impact Police Data, Predictive Policing Systems, and Justice")).
###
2.2. ‘Long-term’ issues
‘Long-term’ issues are often characterised as those arising from advanced AI systems, or simply as issues that will arise far into the future. Brundage (Brundage, [2017](#bib.bib34 "Guide to working in AI policy and strategy")) defines long-term issues as those that “either only arise at all or arise to a much greater extent when AI is much more advanced than it is today”, while Cave and ÓhH́igeartaigh (Cave and ÓhÉigeartaigh, [2019](#bib.bib35 "Bridging near- and long-term concerns about AI")) point to “longer-term concerns and opportunities that are less certain” (p.5). Examples of long-term issues often centre around the implications of very advanced future AI with broad capabilities (‘artificial general intelligence’, or AGI), which achieve human or superhuman intelligence (‘human-level AI’ or ‘superintelligence’), or are in some other way radically transformative (Karnofsky, [2016](#bib.bib27 "Potential Risks from Advanced Artificial Intelligence: The Philanthropic Opportunity")). For example, the White House Report on Preparing for the Future of Artificial Intelligence talks about “long-term concerns of AGI”, implicitly equating the two (Science and House), [2016](#bib.bib17 "Preparing For The Future Of Artificial Intelligence")). While thinking about ‘long-term’ concerns of AI may have begun with concerns about superintelligence and related notions (Bostrom, [2014](#bib.bib26 "Superintelligence: Paths, Dangers, Strategies")), the notion has since broadened to include challenges that are likely to have long-term consequences, as opposed to merely arising far into the future. Examples include the effects of advanced, ‘transformative AI’ on international security, race dynamics and power relations (Karnofsky, [2016](#bib.bib27 "Potential Risks from Advanced Artificial Intelligence: The Philanthropic Opportunity"); Dafoe, [2018](#bib.bib18 "AI Governance: A Research Agenda"); Gruetzemacher and Whittlestone, [2019](#bib.bib16 "Defining and Unpacking Transformative AI")).
###
2.3. The divide between ‘near-term’ and ‘long-term’ communities
Baum (Baum, [2018](#bib.bib31 "Reconciliation between factions focused on near-term and long-term artificial intelligence")) not only distinguishes between near and long-term issues, but also points to a divide between two different communities: ‘presentists’, who claim that “attention should go to existing and near-term AI”, and ‘futurists’, who argue for focusing on “the potential for radically transformative AI”. Cave and ÓhÉigeartaigh (Cave and ÓhÉigeartaigh, [2019](#bib.bib35 "Bridging near- and long-term concerns about AI")) also point to “two seemingly separate communities of researchers and technologists” focused on near and long-term issues.
Baum suggests these two groups disagree quite fundamentally about what issues are most important to work on. This has provoked hostility between the two sides: the ‘near-term’ camp suggesting that long-term concerns are overblown and a distraction from real problems (Etzioni, [2016](#bib.bib23 "No, the Experts Don’t Think Superintelligent AI is a Threat to Humanity"); Crawford and Calo, [2016](#bib.bib15 "There is a blind spot in AI research")), while some in the ‘long-term’ camp suggest that the problems they focus on dwarf any near-term concerns in importance (Tegmark, [2017](#bib.bib14 "Life 3.0: being human in the age of artificial intelligence"); Bostrom, [2014](#bib.bib26 "Superintelligence: Paths, Dangers, Strategies")). This adversarial dynamic seems to be at the core of proposals to ‘reconcile’ or ‘bridge’ the two sides (Baum, [2018](#bib.bib31 "Reconciliation between factions focused on near-term and long-term artificial intelligence"); Cave and ÓhÉigeartaigh, [2019](#bib.bib35 "Bridging near- and long-term concerns about AI")).
3. The problem with the near/long-term distinction
---------------------------------------------------
‘Near-term’ and ‘long-term’ are often used in ways that combine and conflate multiple different dimensions, including: when issues arise; what kinds of technological capabilities issues relate to; how well-understood or speculative issues are; how high-stakes issues are and how many people they affect; and how long-lasting the consequences of an issue are likely to be. As table [1](#S4.T1 "Table 1 ‣ 4.1. Unpacking the near/long-term distinction ‣ 4. A clearer account of research priorities and disagreements ‣ Beyond Near- and Long-Term: Towards a Clearer Account of Research Priorities in AI Ethics and Society") shows, even a single definition or paper sometimes associates ‘near-term’ with one of these dimensions and ‘long-term’ with another: Brundage (Brundage, [2017](#bib.bib34 "Guide to working in AI policy and strategy")), for example, defines ‘near-term’ based on when issues arise and ‘long-term’ in terms of technological capabilities.
Rather than describing a single dimension, we suggest that the distinction between near- and long-term as currently used is better understood as describing clusters of issues, incorporating multiple dimensions:
* Issues considered ‘near-term’ tend to be those arising in the present/near future as a result of current/foreseeable AI systems and capabilities, on varying levels of scale/severity, which mostly have immediate consequences for people and society.
* Issues considered ‘long-term’ tend to be those arising far into the future as a result of large advances in AI capabilities (with a particular focus on notions of transformative AI or AGI), and those that are likely to pose risks that are severe/large in scale with very long-term consequences.
We believe that carving up the AI E&S research space according to these clusters is problematic in two key ways. First, important and nuanced information gets lost if we give too much prominence to only two clusters. Many beliefs, values and assumptions will vary within each of these clusters. For example, among those who believe we should prioritise risks from advanced AI systems, there seems to be substantial disagreement about why exactly those risks are most important to work on, and what work should be done today to prevent those risks (Sittler, [2019](#bib.bib12 "A shift in arguments for AI risk"); Ngo, [2019](#bib.bib13 "Disentangling arguments for the importance of AI safety")). Similarly, there are many different reasons a group may choose to focus on issues arising from current applications of AI in society: because they believe we should prioritise helping people alive today, because they believe advanced AI systems are very far off or hard to predict, or because they believe today’s problems are as high-stakes as anything we might face in the future. As we will discuss later, a binary distinction may have led the research community to neglect impacts which fall somewhere between ‘immediate’ and ‘very long-term’ (Parson et al., [2019](#bib.bib33 "Artificial Intelligence in Strategic Context: An Introduction")).
Second, giving too much prominence to the ‘near-term’ and ‘long-term’ clusters without examining underlying beliefs can lead researchers who identify with either side to end up misunderstanding each other. For example, Etzioni (Etzioni, [2016](#bib.bib23 "No, the Experts Don’t Think Superintelligent AI is a Threat to Humanity")) argues against the idea that superhuman AI could pose an existential threat to humanity (most prominently argued by Bostrom, (Bostrom, [2014](#bib.bib26 "Superintelligence: Paths, Dangers, Strategies"))) by drawing on survey data to suggest that experts do not believe superhuman AI systems will arrive any time soon. But as Dafoe and Russell (Dafoe and Russel, [2016](#bib.bib24 "Yes, We Are Worried About the Existential Risk of Artificial Intelligence")) point out in response, Bostrom’s argument does not actually rely on any assumptions about superintelligence being imminent. In practice, Etzioni and Bostrom’s disagreement turns more on how important and tractable they think it is to work on the potential risks from superhuman AI today. The idea that there are two ‘camps’ of AI E&S researchers, with very opposing perspectives, may lead researchers like Etzioni and Bostrom to make unfounded assumptions about the others’ perspective, and prevent them from engaging in more substantive and productive debate.
At its core, the distinction between near and long-term in AI E&S aims to capture the idea that different researchers and groups will sometimes have quite different priorities which guide what they work on, underpinned by some quite fundamental disagreements. We believe that acknowledging these differences is useful, but suggest that we need a clearer way to think and communicate about what they are. In the following section, we propose exactly that - some clearer ways to communicate about different research priorities and underlying disagreements.
4. A clearer account of research priorities and disagreements
--------------------------------------------------------------
###
4.1. Unpacking the near/long-term distinction
As commonly used, the terms ‘near-term’ and ‘long-term’ in fact appear to capture four different dimensions of differing priorities within the AI E&S research community:
* Capabilities: whether to focus on the impacts and challenges of current AI systems, or those relating to much more advanced AI systems
* Impacts: whether to focus mostly on the immediate impacts of AI for society, or whether to consider possible impacts much further into the future.
* Certainty: whether to focus on impacts and issues that are relatively certain and well-understood, or those that are more uncertain and speculative.
* Extremity: whether to focus on impacts at all scales, or to prioritise focusing on those that may be particularly large in scale.
None of these four dimensions are binary: one can choose research questions that focus on AI systems that are more or less advanced, exploring impacts on varying time horizons, with varying degrees of certainty and extremity. Table [1](#S4.T1 "Table 1 ‣ 4.1. Unpacking the near/long-term distinction ‣ 4. A clearer account of research priorities and disagreements ‣ Beyond Near- and Long-Term: Towards a Clearer Account of Research Priorities in AI Ethics and Society") shows how these four dimensions in definitions of ‘near-term’ and ‘long-term’ by different authors.
| Dimension | ’Near-term’ | ’Long-term’ |
| --- | --- | --- |
|
AI Capabilities | “Attention should go to existing and near-term AI” (Baum, [2018](#bib.bib31 "Reconciliation between factions focused on near-term and long-term artificial intelligence"), p.2) | “Issues that either only arise at all or arise to a much greater extent when AI is much more advanced than it is today, and in particular if advances turn out to be rapid.” (Brundage, [2017](#bib.bib34 "Guide to working in AI policy and strategy"))
“Attention should go to the potential for radically transformative long-term AI” (Baum, [2018](#bib.bib31 "Reconciliation between factions focused on near-term and long-term artificial intelligence"), p.2) |
|
Impacts | “Issues society is grappling with today.” (Brundage, [2017](#bib.bib34 "Guide to working in AI policy and strategy"))
“Extant or imminently anticipated AI applications that interact with existing legal, political, or social concerns” (Parson et al., [2019](#bib.bib33 "Artificial Intelligence in Strategic Context: An Introduction"), p.5)
“ […] problem X that we are facing today with AI” (Krakovna, [2018](#bib.bib32 "Is There a Trade-Off Between Immediate and Longer-term AI Safety Efforts?")) | “Longer-term concerns and opportunities that are less certain” (Cave and ÓhÉigeartaigh, [2019](#bib.bib35 "Bridging near- and long-term concerns about AI"), p.5) |
| Certainty | “Immediate challenges involving fairly clear players and parameters” (Cave and ÓhÉigeartaigh, [2019](#bib.bib35 "Bridging near- and long-term concerns about AI"), p.5) | “Longer-term concerns and opportunities that are less certain” (Cave and ÓhÉigeartaigh, [2019](#bib.bib35 "Bridging near- and long-term concerns about AI"), p.5) |
| Extremity | | “The existential risks of extreme AI advances” (Parson et al., [2019](#bib.bib33 "Artificial Intelligence in Strategic Context: An Introduction"), p.5) |
Table 1. Dimensions underlying the ’near-term’ and ’long-term’ distinction in the literature.
Of course, these dimensions are not entirely independent of one another: for example, if one wants to focus on particularly large-scale impacts of AI, one may have to be willing to consider more speculative questions. However, it is still useful to unpack these different dimensions, particularly because there are many possible views and research questions which are not easily captured by the near/long-term distinction as commonly used.
Looking at these four dimensions, we can identify some differences in what they refer to. ‘Capabilities’ and ‘impacts’ both refer in some sense to time horizons; to whether research focuses on the present (either in terms of AI capabilities or impacts) or whether it looks further into the future. Both these dimensions therefore seem to capture different interpretations of what it might mean to say an issue is ‘near-term’ or ‘long-term’. ‘Certainty’ and ‘extremity’, by contrast, do not relate so explicitly to time horizons: instead they relate to the nature of impacts that different researchers might focus on, and our ability to predict and understand these impacts. Although these dimensions do appear in how near and long-term are described, we suggest that they better characterised as capturing the kinds of motivations researchers may have for choosing to work on different areas.
###
4.2. Distinguishing capabilities and impacts
‘Near-term’ and ‘long-term’ are often modifiers applied to the state of technological capabilities themselves, with near-term issues being those arising from the AI systems we have today (Parson et al., [2019](#bib.bib33 "Artificial Intelligence in Strategic Context: An Introduction")), and long-term issues being those we might expect to arise from certain kinds of much more advanced AI systems (Brundage, [2017](#bib.bib34 "Guide to working in AI policy and strategy")). At other times, ‘near-term’ and ‘long-term’ refer rather to the impacts of the technology: with near-term issues being the impacts of AI that society already faces or will face in the immediate future (Brundage, [2017](#bib.bib34 "Guide to working in AI policy and strategy")), and long-term issues being the impacts of AI that society might face very far into the future (Cave and ÓhÉigeartaigh, [2019](#bib.bib35 "Bridging near- and long-term concerns about AI")).
Of course the timescale of technological advances and their impacts on society will be related. However, conflating long-term capabilities and impacts may mean the research community neglect important questions about the potential long-term impacts of current AI systems and their applications in society. For example, in what ways could injustices perpetuated by increased use of current algorithmic systems have very long-lasting and irreversible consequences for inequality in society? What are the possible longer-term implications of how data-intensive AI applications are beginning to change norms around privacy and personal data? (Newell and Marabelli, [2015](#bib.bib1 "Strategic opportunities (and challenges) of algorithmic decision-making: a call for action on the long-term societal effects of ‘datification’"))
Furthermore, it is important to recognise that both capabilities and impacts lie on a spectrum between near- and long-term. Understanding the potential ‘medium-term’ impacts of AI on society - for example, exploring what different sectors and domains might look like in 5-10 years as a result of current trends in AI development and deployment - is likely to be important both for thinking about what we can do today to protect against future harms, and for preparing for longer-term impacts and scenarios. Similarly, there are many ways in which AI systems could become more advanced over the coming years, before reaching anything close to ‘superintelligence’ or ‘AGI’. We need to consider what issues these intermediate advances might raise, and what kinds of intermediate advances in capabilities are mostly likely to be of harm or benefit for society.
Figure [1](#S4.F1 "Figure 1 ‣ 4.2. Distinguishing capabilities and impacts ‣ 4. A clearer account of research priorities and disagreements ‣ Beyond Near- and Long-Term: Towards a Clearer Account of Research Priorities in AI Ethics and Society") shows how considering these two dimensions of capabilities and impacts, each sitting on a spectrum, allows for more nuanced categorisation of different types of issues.

Figure 1. Distinguishing issues based on capabilities and impacts.
This way of conceptualising the research space could also be used to situate different research groups or research agendas. For example, AI Now’s research seems to sit pretty squarely in the bottom left-hand corner (Whittaker et al., [2018](#bib.bib25 "AI now report 2018")); the Centre for the Governance of AI at Oxford focuses mostly on issues at the top of the plot but spanning left to right (Dafoe, [2018](#bib.bib18 "AI Governance: A Research Agenda")); and the Centre for the Future of Intelligence at Cambridge works on issues across a much wider range of the plot. Both authors of this paper see their research as mostly focusing in the upper-left quadrant - i.e. considering the medium-to-long-term impacts of near-to-medium-term AI capabilities, primarily because these issues have thus far been more neglected in discourse and research around AI E&S impacts (Parson et al., [2019](#bib.bib33 "Artificial Intelligence in Strategic Context: An Introduction")).
Of course, this still contains considerable ambiguity and room for disagreement, and placing different issues on these axes requires making assumptions about questions we don’t necessarily have good answers to. Is there really good reason to think that advanced AI systems will pose an existential threat to humanity, or that advances in AI capabilities might pose a threat to democracy with long-lasting consequences? We believe that provoking productive debate and discussion on questions like these could in fact be a valuable consequence of this way of conceptualising the research space. However, we also recognise that any two-dimensional plot is limited in its ability to capture more fundamental reasons why people have those different priorities. We therefore next turn to a discussion of some of the beliefs and motivations underpinning different approaches in the AI E&S research space.
###
4.3. Underlying beliefs and motivations
One question that has not been explored in existing discussions of the near/long-term distinction is why different researchers and groups have different priorities. The idea of focusing on impacts that are more or less certain and more or less extreme are present in some definitions of near and long-term (see table [1](#S4.T1 "Table 1 ‣ 4.1. Unpacking the near/long-term distinction ‣ 4. A clearer account of research priorities and disagreements ‣ Beyond Near- and Long-Term: Towards a Clearer Account of Research Priorities in AI Ethics and Society")); we suggest that these dimensions may be best understood as capturing some of the underlying motivations people have for focusing on certain types of research questions.
One reason to focus on researching the longer-term impacts of AI, and/or the impacts of more advanced capabilities, is that those impacts might be more extreme and so particularly important to manage. Indeed, groups like the Open Philanthropy Project who explicitly prioritise risks from advanced AI state that “all else equal, we’re more interested in artificial developments that would affect more people and more deeply” (Karnofsky, [2016](#bib.bib27 "Potential Risks from Advanced Artificial Intelligence: The Philanthropic Opportunity")). Similarly, a research agenda published by the Future of Humanity Institute in Oxford, typically thought of as an institution with a ‘long-term’ focus, explicitly highlights its “focus on extreme risks” (Dafoe, [2018](#bib.bib18 "AI Governance: A Research Agenda")).
The idea that immediate impacts of AI and/or those relating to current AI systems are more certain and well-understood is also sometimes invoked as a reason to work on those issues (or as an argument against focusing on advanced capabilities and long-term impacts.) For example, Andrew Ng explains that the reason he is not concerned about advanced AI is “the same reason I don’t worry about overpopulation on Mars… we’ve never set foot on the planet so how can we productively worry about this problem now?” (Garling, [2015](#bib.bib19 "Andrew Ng: Why ‘Deep Learning’ is a mandate for humans, not just machines.")). Relatedly, criticisms of those who focus on potential existential risks from AI often make the argument that these worries are too speculative, and are “a distraction from the very real problems with artificial intelligence today” (Crawford, [2016](#bib.bib22 "Artifical Intelligence’s White Guy Problem.")).
Working on problems that may have very extreme impacts on humanity, and working on problems that are certain and well-understood today are somewhat in tension with one another, and this tension is perhaps a central driver of the divide between ‘long-term’ and ‘near-term’ communities in AI E&S. Of course, in line with the main message of this paper, our view is that there is not a simple binary choice between focusing on ‘extreme’ impacts of AI and focusing on ‘certain’ impacts - both exist on a spectrum, and there may be many ways for the AI E&S community to identify areas for research which have relatively high-stakes implications while also being grounded enough in current AI and societal trends to make progress on.
Further dimensions of disagreement may help explain why the AI E&S community has divided in certain ways. Disagreement on normative issues may be relevant here, such as around whether we have a special moral obligation to help those who are alive today over those who will live in future (Parfit, [2017](#bib.bib21 "Future people, the non-identity problem, and person-affecting principles")), or to prioritise helping those worst off in society (Parfit, [1991](#bib.bib20 "Equality or priority")). Someone who holds the more fundamental philosophical belief that we should prioritise helping the worst off in society, for example, is likely to choose to work on the implications of AI for global fairness or social justice, regardless of their position on the certainty/extremity tension as outlined above.
Other disagreements underpinning different priorities may be empirical: disagreements about the nature of problems, or our ability to solve them. Whether one believes it is more important to focus on challenges relating to current or advanced AI systems is likely to depend at least in part on beliefs about AI progress. If you believe we are likely to see very fast and/or discontinuous progress in AI capabilities over the next few years, preparing for the potential impacts of these advances seems much more urgent than if you believe progress will be slow and gradual, giving us time to solve today’s problems before we have to deal with anything more advanced. Indeed, much of the disagreement about whether we should be concerned about advanced AI seems to turn on disagreement about whether large advances in AI capabilities are possible any time soon (Brockman, [2019](#bib.bib2 "Possible Minds: Twenty-Five Ways of Looking at AI"); Ford, [2019](#bib.bib11 "Architects of Intelligence: The truth abut AI from the people building it")). Which specific impacts one chooses to focus on may also depend on empirical beliefs about the severity of different issues: how damaging to society threats to privacy might be in the long-term, and/or how likely advanced AI systems are to pose an existential threat, for example.
Beliefs about our ability to forecast and/or influence the future are also relevant - often scepticism about research on advanced AI systems seems to stem from doubts about our ability to productively work on these problems. Andrew Ng’s statement quoted earlier (Garling, [2015](#bib.bib19 "Andrew Ng: Why ‘Deep Learning’ is a mandate for humans, not just machines.")) appears to express this kind of scepticism: that we can’t ‘productively’ work on the impacts of advanced AI systems.
5. Recommendations and conclusion
----------------------------------
The field of research concerned with the impact of AI on society and humanity is fast growing. Due to the cross-cutting and interdisciplinary nature of these issues, it is useful to be able to carve up the research space in ways that go beyond traditional disciplinary or thematic boundaries in academia, and capture different underlying assumptions about what the most important problems in this space are. We propose more nuanced ways to do this that better capture this rich and complex research space, breaking down the binary distinction between ‘near-term’ and ‘long-term’ into four different dimensions: capabilities, impacts, certainty and extremity, and emphasising that all of these sit on a spectrum.
Based on this analysis, we have a few concrete recommendations for how the AI E&S research community can encourage more nuanced and productive discussion about different priorities and assumptions:
* Be specific about what you mean when using ‘near-term’ or ‘long-term’ to refer to research priorities or projects. As outlined in the previous section, we think it would be particularly useful if there was a clearer distinction between (a) immediate vs. long-term impacts on society, and (b) current vs. much more advanced AI capabilities, and if there were greater acknowledgement that in both cases ‘near to long-term’ is a spectrum, not a binary distinction.
* Communicate clearly and explicitly about the assumptions and beliefs underlying your projects and priorities, especially around some of the questions highlighted above. A good example of this is the preface to Dafoe’s (Dafoe, [2018](#bib.bib18 "AI Governance: A Research Agenda")) research agenda, which explicitly states its focus on extreme risks from advanced AI (though they could go even further to explain the reasoning behind this decision.) Another good example is Parson et al. (Parson et al., [2019](#bib.bib33 "Artificial Intelligence in Strategic Context: An Introduction")) who clearly state that their project focuses on the “intermediate scale of AI impacts, time horizons, and implications” since this is where their expertise is most relevant, and where areas of potential importance are receiving relatively less attention.
* Make an effort to understand the underlying motivations and assumptions of others with different research priorities, again using some of the questions outlined in the previous section as a starting point. Conferences, workshops and journals could potentially help support this by providing fora for researchers to debate such fundamental questions and disagreements, improving mutual understanding.
By taking these steps, we hope the AI E&S research community can: (a) establish new opportunities for collaboration and reduce adversarial dynamics, while allowing for differences of opinion and approach; (b) develop more consistent and coherent research agendas by helping researchers to think more clearly about what they prioritise; and (c) identify neglected research areas which may have been overlooked due to not fitting neatly into existing ways of characterising the research space. |

Crossposted from: Equilibria Club
It's time for a puzzle involving two fields: game theory and cryptography! Both fields model self-interested agents in a competitive setting. In game theory, we list actions and payoffs, after which we can determine which actions will benefit agents the most. In cryptography, we model actions to ensure agents only get a limited amount of information.
Comparison of concepts between cryptography and game theory
----------------------------------------
The problem: game of chicken
To illustrate how cryptography can be used to achieve better outcomes in a game, we're going to look at the "Game of Chicken". Imagine two players driving towards each other in a car, in principle wanting to avoid a collision, but also not wanting to chicken out. The standard two-player game is characterized by the following payoffs:
Player 1 cooperatesPlayer 1 defectsPlayer 2 cooperates(4, 4)(1, 5)Player 2 defects(5, 1)(0, 0)
> "While the “wisest” pair of actions is (C, C), this is not a Nash equilibrium, since both players are willing to deviate (believing that the other player will stay at C)."
----------------------------------------
We can display the three Nash equilibria (the optimal actions for non-coordinating self-interested players) on a graph. The players will either (cooperate, defect), (defect, cooperate), or have a 50% chance of (cooperate, defect) and (defect, cooperate).
Three Nash equilibria in the extended game
In the previous post about game theory, I referred to the Folk Theorem of game theory, which says that many equilibria can be enforced by the players in iterated games. However, those enforceable equilibria all fall in the so-called convex hull of the Nash equilibria - which is any situation contained by the Nash equilibria. In the Game of Chicken, situations in the convex hull are all situations below the purple diagonal, leading to a maximum total payoff of 6. Is there any way we can do better? Well yes! We can try to a |
911ffe82-4d48-4cdc-ab6b-2c257c1a5306 | LDJnr/LessWrong-Amplify-Instruct | LessWrong | "If you ever find yourself saying, "Even if Hypothesis H is true, it doesn't have any decision-relevant implications," you are rationalizing! The fact that H is interesting enough for you to be considering the question at all (it's not some arbitrary trivium like the 1923th binary digit of π, or the low temperature in São Paulo on September 17, 1978) means that it must have some relevance to the things you care about. It is vanishingly improbable that your optimal decisions are going to be the same in worlds where H is true and worlds where H is false. The fact that you're tempted to say they're the same is probably because some part of you is afraid of some of the imagined consequences of H being true. But H is already true or already false! If you happen to live in a world where H is true, and you make decisions as if you lived in a world where H is false, you are thereby missing out on all the extra utility you would get if you made the H-optimal decisions instead! If you can figure out exactly what you're afraid of, maybe that will help you work out what the H-optimal decisions are. Then you'll be a better position to successfully notice which world you actually live in."
The above is a chunk of text from a post created by a user on the website LessWrong.
What potential problems could arise from assuming that the optimal decisions will always differ in worlds where H is true and where H is false?
Assuming that optimal decisions will always differ in worlds where H is true and where H is false could lead to several potential problems:
1. Overcomplication: This assumption may lead to overcomplication of decision-making processes. Sometimes, the optimal decision may be the same regardless of whether H is true or false. Assuming otherwise could lead to unnecessary complexity and confusion.
2. Ignoring Overlapping Solutions: There could be overlapping solutions or decisions that are optimal in both scenarios. By assuming that decisions must differ, one might overlook these common solutions that could be more efficient or beneficial.
3. False Dichotomy: This assumption could lead to a false dichotomy, where decisions are seen as only being optimal in one scenario or the other, but not both. This can limit the range of potential solutions considered.
4. Misallocation of Resources: If one assumes that different scenarios require different optimal decisions, it could lead to a misallocation of resources. Time and effort might be wasted on creating separate strategies for each scenario, even when a single strategy could have been effective for both.
5. Potential for Bias: This assumption could potentially introduce bias into the decision-making process. If one is convinced that the truth or falsehood of H must necessarily lead to different decisions, they might unconsciously favor solutions that align with their personal beliefs about H.
6. Ignoring Context: The assumption doesn't take into account the context in which the decision is being made. There might be external factors that make the same decision optimal whether H is true or false.
In conclusion, while considering different decisions for different scenarios can be beneficial, it's important to not rigidly adhere to this assumption. There may be situations where the same decision is optimal, regardless of the truth or falsehood of H.
Reflecting on the potential issues you outlined, could there be situations where the assumption of differing optimal decisions in the face of H being true or false might actually be beneficial?
Yes, there are indeed situations where the assumption of differing optimal decisions, depending on whether H is true or false, could be beneficial. Here are a few examples:
1. Complex Systems: In complex systems or situations, where there are multiple variables and outcomes at play, assuming different optimal decisions for different states of H can help in thoroughly exploring all possible scenarios and outcomes. This can lead to more robust decision-making.
2. Risk Management: In risk management, assuming different decisions for different scenarios can be a form of contingency planning. This allows for preparedness in the face of uncertainty and can help mitigate potential risks.
3. Innovation and Creativity: This assumption can also stimulate innovative thinking and creativity. By considering different decisions for different scenarios, one might come up with unique solutions that wouldn't have been considered otherwise.
4. Learning Opportunities: The process of considering different decisions based on different states of H can provide valuable learning opportunities. It can help in understanding the dynamics of the situation better and can lead to the development of more effective decision-making strategies in the future.
5. Ensuring Fairness: In situations where decisions impact different groups of people differently, considering different decisions for different scenarios can help ensure fairness and equity. This can be particularly important in policy-making and governance.
In conclusion, while there can be drawbacks to assuming different optimal decisions for different states of H, there can also be significant benefits in certain situations. The key is to apply this assumption judiciously, taking into account the specific context and potential implications.
Discuss the role of contingency planning in risk management, particularly in scenarios where the truth or falsehood of a hypothesis significantly alters the optimal decision.
Contingency planning plays a critical role in risk management, particularly in scenarios where the truth or falsehood of a hypothesis significantly alters the optimal decision. Here's how:
1. Preparedness: Contingency planning prepares an organization for unexpected events or scenarios. If a hypothesis turns out to be true or false, a well-prepared contingency plan can provide a roadmap for action, reducing panic and confusion.
2. Reducing Impact: By identifying potential risks and outlining steps to mitigate them, contingency planning can significantly reduce the negative impact of an unexpected event. This is particularly important when the truth or falsehood of a hypothesis could significantly alter the situation.
3. Resource Allocation: Contingency planning helps in efficient resource allocation. By planning in advance for different scenarios, an organization can ensure that resources are available and can be quickly mobilized when needed.
4. Business Continuity: In the face of significant risks, contingency planning can help ensure business continuity. It allows an organization to quickly adapt and respond to changes, minimizing disruption to operations.
5. Decision Making: Contingency planning supports decision-making in uncertain situations. When the truth or falsehood of a hypothesis significantly alters the optimal decision, having a contingency plan can provide a clear path forward, reducing uncertainty and facilitating swift decision-making.
In scenarios where a hypothesis plays a significant role, contingency planning involves creating different plans based on whether the hypothesis is true or false. Each plan would outline the steps to take, resources required, and potential challenges and solutions, enabling the organization to respond effectively no matter the outcome. It's a proactive approach that recognizes the uncertainty inherent in any situation and prepares for it in advance. |

I've gotten sufficient evidence from support that voiceofra has been doing retributive downvoting. I've banned them without prior notice because I'm not giving them more chances to downvote.
I'm thinking of something like not letting anyone give more than 5 downvotes/week for content which is more than a month old. The numbers and the time period are tentative-- this isn't my ideal rule. This is probably technically possible. However, my impression is that highly specific rules like that are an invitation to gaming the rules.
I would rather just make spiteful down-voting impossible (or maybe make it expensive) rather than trying to find out who's doing it. Admittedly, putting up barriers to downvoting for past comments doesn't solve the problem of people who down-vote everything, but at least people who downvote current material are easier to notice.
Any thoughts about technical solutions to excessive down-voting of past material? |

Assume for the time being that it will forever remain beyond the scope of science to change Human Nature. AGI is also impossible, as is Nanotech, BioImmortality, and those things.
Douglas Adams mice finished their human experiment, giving to you, personally, the job of redesigning earth, and specially human society, according to your wildest utopian dreams, but you can't change the unchangeables above.
You can play with architecture, engineering, gender ratio, clothing, money, science grants, governments, feeding rituals, family constitution, the constitution itself, education, etc... Just don't forget if you slide something too far away from what our evolved brains were designed to accept, things may slide back, or instability and catastrophe may ensue.
Finally, if you are not the kind of utilitarian that assigns exactly the same amount of importance to your desires, and to that of others, I want you to create this Utopia for yourself, and your values, not everyone.
The point of this exercise is: The vast majority of folk not related to this community that I know, when asked about an ideal world, will not change human nature, or animal suffering, or things like that, they'll think about changing whatever the newspaper editors have been writing about last few weeks. I am wondering if there is symmetry here, and folks from this community here do not spend that much time thinking about those kinds of change which don't rely on transformative technologies. It is just an intuition pump, a gedankenexperiment if you will. Force your brain to face this counterfactual reality, and make the best world you can given those constraints. Maybe, if sufficiently many post here, the results might clarify something about CEV, or the sociology of LessWrongers...

19f9d17e-a12d-46e6-9d63-398b017d42ae | trentmkelly/LessWrong-43k | LessWrong | Why there are no online CFAR workshops?
As there are many people here here who attended CFAR workshops, I wanted to ask, if you understand why there are no online workshops, even when the in-person workshops were not possible due to the pandemic. In my experience, everything that does not require physical contact (like martial arts) can be taught online. There can be some inconveniences, of course, but if planned well, it can work quite smoothly. I can think about very small amount of reasons, and none of them seems persuasive to me.
1. Maybe CFAR workshop indeed requires physical contact? Sounds quite strange.
2. Maybe organizers are not good with technologies and don't know how to do different Zoom rooms, how to make parties in Mozilla Hubs etc.? Maybe they have never heard about properly organized online schools? Sounds even less likely.
3. Maybe CFAR workshop requires full embedding with no distraction? Well, it can be clarified in the announcement as a requirement for the participants, and for many people, it is certainly a possible thing to do.
4. Maybe CFAR somehow got into a death spiral and turned into something like Lifespring? I would hope it is unlikely in the rationalistic community, but here is more hope than actual belief. |
92dee6ab-e3a0-4283-98ed-9073f2686276 | LDJnr/LessWrong-Amplify-Instruct | LessWrong | "Written with much help from Nick Tarleton and Kaj Sotala, in response to various themes here, here, and throughout Less Wrong; but a casual mention here1 inspired me to finally write this post. (Note: The first, second, and third footnotes of this post are abnormally important.)
It seems to have become a trend on Less Wrong for people to include belief in the rationality of signing up for cryonics as an obviously correct position2 to take, much the same as thinking the theories of continental drift or anthropogenic global warming are almost certainly correct. I find this mildly disturbing on two counts. First, it really isn't all that obvious that signing up for cryonics is the best use of one's time and money. And second, regardless of whether cryonics turns out to have been the best choice all along, ostracizing those who do not find signing up for cryonics obvious is not at all helpful for people struggling to become more rational. Below I try to provide some decent arguments against signing up for cryonics — not with the aim of showing that signing up for cryonics is wrong, but simply to show that it is not obviously correct, and why it shouldn't be treated as such. (Please note that I am not arguing against the feasibility of cryopreservation!) Signing up for cryonics is not obviously correct, and especially cannot obviously be expected to have been correct upon due reflection (even if it was the best decision given the uncertainty at the time): Weird stuff and ontological confusion: quantum immortality, anthropic reasoning, measure across multiverses, UDTesque 'decision theoretic measure' or 'probability as preference', et cetera, are not well-understood enough to make claims about whether or not you should even care about the number of 'yous' that are living or dying, whatever 'you' think you are.3 This does not make cryonics a bad idea — it may be the correct decision under uncertainty — but it should lessen anyone's confidence that the balance of reasons ultimately weighs overwhelmingly in favor of cryonics.
If people believe that a technological singularity is imminent, then they may believe that it will happen before they have a significant chance of dying: either everyone (including cryonauts) dies anyway when an unFriendly artificial intelligence goes FOOM, or a Friendly artificial intelligence is created and death is solved (or reflectively embraced as good, or some other unexpected outcome). This is more salient when considering the likelihood of large advances in biomedical and life extension technologies in the near future.
A person might find that more good is done by donating money to organizations like SENS, FHI, or SIAI4 than by spending that money on pursuing a small chance of eternal life. Cryonics working is pretty dependent on e.g. an unFriendly artificial intelligence not going FOOM, or molecular nanotechnology not killing everyone. Many people may believe that a slightly higher chance of a positive singularity is more important than a significantly higher chance of personal immortality. Likewise, having their friends and family not be killed by an existential disaster such as rogue MNT, bioweaponry, et cetera, could very well be more important to them than a chance at eternal life. Acknowledging these varied preferences, and varied beliefs about one's ability to sacrifice only luxury spending to cryonics, leads to equally varied subjectively rational courses of action for a person to take.
Some people may have loose boundaries around what they consider personal identity, or expect personal identity to be less important in the future. Such a person might not place very high value on ensuring that they, in a strong sense, exist in the far future, if they expect that people sufficiently like them to satisfy their relevant values will exist in any case. (Kaj Sotala reports being indifferent to cryonics due to personal identity considerations here.) Furthermore, there exist people who have preferences against (or no preferences either for or against) living extremely far into the future for reasons other than considerations about personal identity. Such cases are rare, but I suspect less rare among the Less Wrong population than most, and their existence should be recognized. (Maybe people who think they don't care are usually wrong, and, if so, irrational in an important sense, but not in the sense of simple epistemic or instrumental-given-fixed-values rationality that discussions of cryonics usually center on.)
That said, the reverse is true: not getting signed up for cryonics is also not obviously correct. The most common objections (most of them about the infeasibility of cryopreservation) are simply wrong. Strong arguments are being ignored on both sides. The common enemy is certainty. Calling non-cryonauts irrational is not productive nor conducive to fostering a good epistemic atmosphere: Whether it's correct or not, it seems unreasonable to claim that the decision to forgo cryonics in favor of donating (a greater expected amount) to FHI, SIAI4, SENS, etc. represents as obvious an error as, for instance, religion. The possibility of a third option here shouldn't be ignored.
People will not take a fringe subject more seriously simply because you call them irrational for not seeing it as obvious (as opposed to belief in anthropogenic global warming where a sheer bandwagon effect is enough of a memetic pull). Being forced on the defensive makes one less likely to accept and therefore overcome their own irrationalities, if irrationalities they are. (See also: A Suite of Pragmatic Considerations in Favor of Niceness)
As mentioned in bullet four above, some people really wouldn't care if they died, even if it turned out MWI, spatially infinite universes, et cetera were wrong hypotheses and that they only had this one shot at existence. It's not helping things to call them irrational when they may already have low self-esteem and problems with being accepted among those who have very different values pertaining to the importance of continued subjective experience. Likewise, calling people irrational for having kids when they could not afford cryonics for them is extremely unlikely to do any good for anyone. Debate over cryonics is only one of many opportunities for politics-like thinking to taint the epistemic waters of a rationalist community; it is a topic where it is easy to say 'we are right and you are wrong' where 'we' and 'you' are much too poorly defined to be used without disclaimers. If 'you' really means 'you people who don't understand reductionist thinking', or 'you people who haven't considered the impact of existential risk', then it is important to say so. If such an epistemic norm is not established I fear that the quality of discourse at Less Wrong will suffer for the lack of it.
One easily falls to the trap of thinking that disagreements with other people happen because the others are irrational in simple, obviously flawed ways. It's harder to avoid the fundamental attribution error and the typical mind fallacy, and admit that the others may have a non-insane reason for their disagreement. 1 I don't disagree with Roko's real point, that the prevailing attitude towards cryonics is decisive evidence that people are crazy and the world is mad. Given uncertainty about whether one's real values would endorse signing up for cryonics, it's not plausible that the staggering potential benefit would fail to recommend extremely careful reasoning about the subject, and investment of plenty of resources if such reasoning didn't come up with a confident no. Even if the decision not to sign up for cryonics were obviously correct upon even a moderate level of reflection, it would still constitute a serious failure of instrumental rationality to make that decision non-reflectively and independently of its correctness, as almost everyone does. I think that usually when someone brings up the obvious correctness of cryonics, they mostly just mean to make this observation, which is no less sound even if cryonics isn't obviously correct.
2 To those who would immediately respond that signing up for cryonics is obviously correct, either for you or for people generally, it seems you could mean two very different things: Do you believe that signing up for cryonics is the best course of action given your level of uncertainty? or, Do you believe that signing up for cryonics can obviously be expected to have been correct upon due reflection? (That is, would you expect a logically omniscient agent to sign up for cryonics in roughly your situation given your utility function?) One is a statement about your decision algorithm, another is a statement about your meta-level uncertainty. I am primarily (though not entirely) arguing against the epistemic correctness of making a strong statement such as the latter.
3 By raising this point as an objection to strong certainty in cryonics specifically, I am essentially bludgeoning a fly with a sledgehammer. With much generalization and effort this post could also have been written as 'Abnormal Everything'. Structural uncertainty is a potent force and the various effects it has on whether or not 'it all adds up to normality' would not fit in the margin of this post. However, Nick Tarleton and I have expressed interest in writing a pseudo-sequence on the subject. We're just not sure about how to format it, and it might or might not come to fruition. If so, this would be the first post in the 'sequence'.

Could you further elaborate on the potential ethical implications of cryonics, particularly in the context of resource allocation and societal impact?
Cryonics involves preserving a person's body at extremely low temperatures with the hope that future medical technology will be able to revive them. It's a concept that raises numerous ethical questions, particularly when it comes to resource allocation and societal impact.
From a resource allocation perspective, cryonics is an expensive procedure that requires significant financial investment. This raises questions about the equitable distribution of resources. If only a small portion of the population can afford cryonics, it may contribute to social inequality. It could potentially lead to a situation where the wealthy have access to a form of life extension that is denied to the less affluent.
Furthermore, the resources used for cryonics could be allocated to other areas of healthcare or research that could benefit a larger number of people. For example, investing in public health initiatives, disease prevention, or developing treatments for currently incurable diseases could arguably provide a greater societal benefit.
From a societal impact perspective, the widespread adoption of cryonics could have profound implications. If a significant portion of the population chooses to be cryopreserved, it could lead to overpopulation in the future if and when these individuals are revived. This could strain resources and potentially lead to conflict.
Moreover, there are questions about the psychological and societal effects of reviving individuals who have been cryopreserved. They would be waking up in a world that could be vastly different from the one they left, potentially leading to significant psychological distress. There are also questions about the legal and societal status of these individuals, and how they would reintegrate into society.
In conclusion, while cryonics offers the tantalizing possibility of life extension, it also raises complex ethical questions that need to be carefully considered. These include issues of resource allocation, social inequality, and the potential societal impact of reviving cryopreserved individuals.
Considering the potential societal implications and ethical dilemmas associated with cryonics, how might governments and regulatory bodies approach the development and implementation of policies related to this practice? Additionally, what could be the potential consequences, both intended and unintended, of such regulations?
The development and implementation of policies related to cryonics would likely be a complex process, requiring input from a variety of stakeholders, including medical professionals, ethicists, legal experts, and the public. Governments and regulatory bodies would need to balance the potential benefits of cryonics with the ethical and societal implications.
One approach could be to regulate cryonics similarly to other medical procedures, requiring rigorous scientific evidence of its safety and efficacy before it can be offered to the public. This could involve establishing standards for cryopreservation and revival procedures, as well as guidelines for informed consent. Such regulations could help ensure that individuals who choose cryonics are fully aware of the risks and uncertainties involved.
Another approach could be to regulate the financial aspects of cryonics. This could involve setting caps on the costs of cryopreservation and revival procedures to prevent exploitation, or implementing measures to ensure that the costs of long-term storage and revival are covered, so as not to burden future generations.
However, these regulations could also have unintended consequences. For instance, strict regulations could potentially stifle innovation in the field of cryonics. On the other hand, if regulations are too lax, there is a risk of unscrupulous providers offering substandard services or making unrealistic promises about the prospects of revival.
Moreover, there could be societal consequences to consider. For instance, if cryonics becomes widely available and accepted, it could change societal attitudes towards death and aging. This could have profound implications for how we value life and allocate resources.
In conclusion, the regulation of cryonics would require careful consideration of a range of ethical, medical, and societal factors. While regulations could help protect individuals and society from potential harms, they could also have unintended consequences that need to be carefully managed. |
