Like the fear and grief systems that it potentiates the amygdala is always active It is |
constantly running its information processing algorithms though usually at a low level Brain |
scans show that the amygdalas activity level rises when we feel threatened It is more active |
at rest in people with anxiety or depressive disorders and less active in those who report being |
happy and well adjusted We can never be certain what will set it off and we often are not |
even aware when it has been activated for more on the amygdala see Chapter |
The amygdala and by extension the fear and grief systems work on the smoke detector |
principle Just like smoke detectors they are calibrated to be so sensitive that they are liable to |
go off by accident They are set this way because a few false alarms are tolerable if it ensures |
that we can recognize real peril when it arises In terms of reproductive success it is better to |
overreact to a nonthreat than to underreact to a true threat This is a reasonable |
predisposition for wild animals but an irrational one for modern humans Today we tolerate |
constant false alarms of the fear and grief systems even though we are rarely confronted by |
physical threats This vestigial hairtrigger mechanism is the reason we are predisposed to |
negative thinking |
The Negativity Bias Fear Grief and Default Mode |
What we are today comes from our thoughts of yesterday and our present thoughts build our life of tomorrow |
our life is the creation of our mind Buddha c BCE BCE |
Humans are a special type of biological survival machine Unlike viruses bacteria protists |
fungi plants and most animals we think We are capable of simulating environmental |
situations so that we can predict the probable outcomes of our actions We use these |
simulations to learn about and make sense of the events around us In a perfect world these |
models would always be cheerful and productive Unfortunately our brains threat centers |
influence us to model negative things so that we can respond appropriately when negative |
scenarios arise This tendency to focus on the bad is often referred to as the negativity bias |
The negativity bias makes us more likely to focus on a negative piece of information such as |
a criticism than a positive one such as a compliment It results in superstitious nonreflective |
fretting that rarely leads to insight or progress Also negative thoughts can be triggered rapidly |
but tend to linger for long periods This is probably related to the poor rebound effect for |
diaphragmatic breathing in which a minor threat can force a mammal to breathe shallowly |
within a single second after which it takes several minutes for the breathing to return |
to normal |
Lamentably rosy glasses dont contribute to reproductive success in most ecological |
scenarios Further animals that dont worry have poor survival outcomes Studies that look at |
fish mice or primates that are bred or experimentally altered to become fearless show that |
these animals are great at acquiring resources but are the first to be eaten On the other |
hand the most anxious animals avoid predators and stay safe However they are not very |
productive or reproductive because they are constantly hiding and cowering So it was good |
for our ancestors to be somewhere between fearful and fearless But what about today |
What about you Would you benefit from being fearless |
Chapter Think Peacefully |
For thousands of millennia our forebears were hunted mauled and devoured by |
monsters These included sabertoothed cats cave lions cave hyenas dire wolves shortfaced |
bears fivemeterlong snakes giant lizards and towering flightless terror birds However |
anatomically modern humans employing expertly fashioned spears clubs axes and knives |
were able to turn the tables For the last thousand years we systematically drove these |
giant beasts of prey to extinction We killed off many of these Cenozoic megafauna for food |
In so doing we made nearly the entire surface of Earth free from predators In the last |
thousand years humans have replaced brutal disputes with courtroom judgments and every |
man for himself with legal rights Compared to our ancestors we should feel invulnerable |
Our world is far safer now Our genes and brains just dont know it yet |
Humans today have virtually no natural predators We fight among each other less than |
ever before and cannibalism is finally out of fashion but our brains fear and grief systems are |
still fully operational The human brain is the pinnacle of evolution on Earth and the most |
complex object in the known galaxy yet it is routinely preoccupied with unsubstantiated fear |
vindictive anger regret victimization resentment and status anxiety When you experience |
these emotions thank your brain for trying to protect you but know that they are vestiges from |
a treacherous anarchic past Anxiety involves a tradeoff The table below lists several similar |
tradeoffs discussed in this book |
