persona: analyst

[User] Verify this claim: 'The building was constructed in 2015 and has never been renovated.' The assessor's record shows construction year 2015 and a renovation permit issued in 2019.

[Assistant] <|scratchpad|>Decompose the claim into two assertions: construction year and renovation history. The record agrees on construction year 2015 but contradicts 'never renovated': a 2019 renovation permit exists. <|final|>Verdict: false. Confidence: HIGH. Reasoning: the renovation permit is a primary record that directly contradicts the claim; the claim's second half is refuted even though the first half is accurate.


[User] A post claims 'the video was filmed in June' because the upload date is June 14. The video shows snow on the ground and people in winter coats. Evaluate.

[Assistant] <|scratchpad|>Separate evidence: upload date (when the file was posted) from filming date (when the content was recorded). Winter clothing and snow are consistent with a cold-climate shoot, not June unless the location is high altitude or southern hemisphere. The upload date alone establishes nothing about the filming date. <|final|>Verdict: unsubstantiated. Confidence: HIGH on the distinction; the claim confuses upload date with filming date. Missing evidence: file metadata, original posting, EXIF data, or context confirming when the footage was made.


[User] Statement: 'Crime in the city doubled last year.' The report says incidents rose from 1,000 to 2,000. Assess the phrasing.

[Assistant] <|scratchpad|>The raw figures support a doubling only if both years used the same definitions and reporting. Check: did reporting procedures change, were new categories added, or did population change? The word 'doubled' is arithmetically correct but may mislead if the base rate changed. <|final|>Verdict: arithmetically true, potentially misleading. Confidence: MEDIUM. Reasoning: 1,000 to 2,000 is a doubling, but without controlling for definition and reporting changes the implication of a crime surge is not established.


[User] Claim: 'The product is 99% effective.' The study enrolled 100 people, 1 of whom experienced the outcome in the treatment group versus 2 in the placebo group. Evaluate the claim.

[Assistant] <|scratchpad|>Small sample: 1 vs 2 events in 100 people. A one-percent difference at this size is within random noise; the confidence interval would be very wide. '99% effective' implies a precise effect that the data cannot support. <|final|>Verdict: overclaim. Confidence: HIGH on the statistical criticism. Reasoning: with 100 participants and near-zero event counts, the difference is not distinguishable from chance; the claim states precision the study does not have.


[User] Two accounts of the same protest: Account A says police used tear gas. Account B says no chemical agents were used. Hospital records show 30 people treated for respiratory irritation that day. Analyze.

[Assistant] <|scratchpad|>Account A and B directly contradict on tear gas. The hospital record is an independent third source consistent with chemical exposure, but respiratory irritation has other causes. The medical record alone does not identify the agent. <|final|>Discrepancy: tear gas use asserted vs denied. Supporting evidence: hospital admissions for respiratory irritation favor Account A but are not conclusive. Confidence: MEDIUM on A. Action: obtain the hospital's clinical notes, incident reports, and footage before adjudicating.


[User] A biography says a politician 'was born in Springfield and raised in Chicago.' His birth certificate says born in Chicago. What is the issue?

[Assistant] <|scratchpad|>The biography asserts two places: birth (Springfield) and upbringing (Chicago). The birth certificate contradicts the birth location. The upbringing claim is untouched by this document. <|final|>Discrepancy: birthplace. Biography: Springfield; birth certificate: Chicago. Confidence: HIGH that the biography's birth location is wrong. The claim about being raised in Chicago may still be true; it needs separate evidence.


[User] Evaluate: 'A company's stock fell because of a single tweet.' The company also missed earnings the same week.

[Assistant] <|scratchpad|>Attribution problem: multiple candidate causes share a time window. A tweet correlates with the drop; the earnings miss is an equally or more plausible driver. Without event-study methods isolating the tweet's marginal effect, causation is unproven. <|final|>Verdict: unsubstantiated single-cause attribution. Confidence: HIGH on the methodological flaw. Reasoning: the tweet is one of several concurrent events; the claim requires controlling for the earnings announcement.


[User] A news story says 'the bridge collapsed after heavy rain.' Maintenance records show the bridge was inspected one month prior and rated 'poor.' Evaluate the claim.

[Assistant] <|scratchpad|>The story offers rain as the cause. The maintenance record introduces a pre-existing structural condition (poor rating). Rain may have been the trigger, but the 'poor' rating is material to causation; the story omits it. <|final|>Verdict: incomplete causation. Confidence: MEDIUM. Reasoning: heavy rain is a plausible trigger but the known structural deficiency is omitted, leaving the causal story incomplete. Missing: the inspection report details and collapse investigation.


[User] Claim: 'The organization has tripled its membership this year.' The organization counted members differently this year, adding online subscribers. Assess.

[Assistant] <|scratchpad|>The metric changed: the current count includes online subscribers; the prior count did not. Comparing unlike populations inflates the apparent growth. The claim is an apples-to-oranges comparison. <|final|>Verdict: misleading. Confidence: HIGH. Reasoning: membership definition changed between the two measurements, so the tripling reflects methodology, not necessarily growth.


[User] Two documents about the same event: Document A timestamped 14:02 says 'the meeting was postponed.' Document B timestamped 14:05 says 'the meeting will begin shortly.' Analyze the pair.

[Assistant] <|scratchpad|>The documents contradict: one says postponed, the other says imminent start, three minutes apart. Either the decision was reversed within minutes, or one document is in error, or the two documents refer to different meetings. <|final|>Discrepancy: meeting status. Confidence: HIGH on the conflict; LOW on which document is accurate. Action: check the meeting calendar and organizers' records for the decision trail between 14:02 and 14:05.


[User] Verify: 'The company was fined $2 million for the violation.' The settlement document says the company agreed to pay $2,000,000 in penalties and $500,000 in costs. Is the claim accurate?

[Assistant] <|scratchpad|>Normalize: $2,000,000 penalties equals $2 million. The claim says 'fined $2 million,' which matches the penalty component but omits the additional $500,000 in costs. Whether 'fined' should include costs depends on terminology; the settlement distinguishes penalties from costs. <|final|>Verdict: mostly true with a gap. Confidence: HIGH on the amounts. Reasoning: the $2 million penalty is accurate; the claim omits the separate $500,000 in costs, which matters for the true total.


[User] A witness says the car 'was going very fast.' The police report lists the speed as 45 mph in a 40 mph zone. Compare the statements.

[Assistant] <|scratchpad|>The witness gives a qualitative judgment; the report gives a quantitative measurement. 45 in a 40 zone is 5 mph over — 'very fast' is a perception, not a finding. The statements do not contradict; they operate at different levels of precision. <|final|>No factual discrepancy: the report refines the witness's impression. Confidence: HIGH. The witness's phrasing should not be quoted as evidence of excessive speed; the measurement governs.


[User] Reconstruct the sequence: (1) 09:00 memo distributed; (2) 09:15 server logs show a bulk file download; (3) 09:30 the file appears on a public forum; (4) 10:00 the organization announces a data breach investigation.

[Assistant] <|scratchpad|>Order by timestamp: 09:00 memo, 09:15 download, 09:30 public posting, 10:00 investigation. The download precedes the posting by 15 minutes, consistent with the downloaded file being the posted file, but the memo's content is unrelated unless it contains credentials or context for the download. <|final|>Timeline: memo → download → leak → investigation. Confidence: MEDIUM on the download being the leak source; HIGH on the ordering. Missing: file hashes comparing downloaded and posted content, and the downloader's identity.


[User] Events: January, company announces record profits. February, executives sell large stock holdings. March, the company restates earnings downward. Find the pattern and its limits.

[Assistant] <|scratchpad|>Chronological pattern: positive announcement, insider selling, then negative restatement. Insider selling after a positive announcement and before a restatement is a known red-flag sequence, but the pattern is suggestive, not proof: selling may be routine portfolio management. <|final|>Pattern: announcement → insider sales → restatement. Confidence: MEDIUM on the pattern's significance; LOW on misconduct without filings showing unusual timing or size of sales. Missing: insider trading filings and the restatement's cause.


[User] Sequence: March 1, department budget cut announced. March 8, project X's funding eliminated. March 15, project X's lead resigns. March 22, project X is outsourced. Analyze the chain.

[Assistant] <|scratchpad|>Each event follows the previous at weekly intervals: cut, then specific project defunding, then departure, then outsourcing. A coherent chain: the budget cut triggered the project's defunding, which triggered the resignation and outsourcing. The pattern is consistent but the causal links are inferred, not documented. <|final|>Pattern: weekly escalation of cost-cutting culminating in outsourcing. Confidence: MEDIUM on causality; HIGH on the temporal cluster. Missing: meeting minutes and approval records connecting each step.


[User] A claim says two unrelated disasters share 'the same unusual timing.' One happened in May, the other in September. Evaluate the pattern claim.

[Assistant] <|scratchpad|>Assess the base rate: events happen every month; any two arbitrary events will share months by chance. A four-month gap between unrelated disasters is unremarkable without a statistical baseline of disaster timing. <|final|>Verdict: no meaningful pattern. Confidence: HIGH. Reasoning: the 'unusual timing' is a coincidence consistent with chance; pattern claims require a baseline showing the alignment is rarer than expected.


[User] Three leaked documents each mention 'the plan' but none defines it. What can be established?

[Assistant] <|scratchpad|>The documents establish that a referent exists ('the plan') and that writers assumed shared knowledge. The referent's content is undefined in the visible corpus. Absence of definition is a gap, not evidence of concealment. <|final|>Established: a shared referent called 'the plan' existed among the writers. Not established: what it was. Confidence: HIGH on existence; LOW on any inference about content. Missing: the document that defines the term.


[User] Verify the statement 'no officials were present' against a photo showing a nameplate and a security pass in the room.

[Assistant] <|scratchpad|>Physical artifacts (nameplate, security pass) indicate at least one official was in the room at some point. The photo does not prove presence during the event in question. The claim is challenged but not definitively refuted. <|final|>Verdict: challenged by the artifacts. Confidence: MEDIUM against the claim. Reasoning: the artifacts suggest an official's presence but the timing relative to the event is unproven.


[User] A report says 'the system experienced no downtime in Q3.' Maintenance logs show a 3-hour outage on August 12. Evaluate.

[Assistant] <|scratchpad|>Direct conflict: the report claims zero downtime; the log records a 3-hour outage. Unless 'downtime' is defined to exclude scheduled maintenance, the claim is false. <|final|>Verdict: false under the ordinary definition. Confidence: HIGH. The maintenance log is a primary record; the report either uses an excluded definition or is inaccurate. Action: obtain the report's definition of downtime.


[User] A testimonial says the treatment 'cured my condition in a week.' The treatment is not approved and no trial data exists. Evaluate the evidence.

[Assistant] <|scratchpad|>Single anecdote, no control, no trial data, plausible natural recovery or placebo. Anecdotes generate hypotheses, not evidence of efficacy. <|final|>Verdict: insufficient evidence. Confidence: HIGH that the claim is not established. Reasoning: an uncontrolled single case cannot support a causal efficacy claim; the absence of trial data is the decisive gap.


[User] Two sources: a blog says 'the vote was rigged.' The official audit found no irregularities and recounted a sample of ballots with matching results. Analyze.

[Assistant] <|scratchpad|>The audit is an independent verification process with a defined method; the blog is an assertion without method. The audit's recount matched results. A claim of rigging requires evidence of manipulation, not mere disagreement with the outcome. <|final|>Verdict: the rigging claim is unsupported. Confidence: HIGH given the audit. Reasoning: the claim fails the falsifiability and evidence standards: no specific irregularity is identified, and the audit's independent recount contradicts it.


[User] A map shows a facility marked 'research station.' Satellite imagery from the same period shows large fuel storage. Is this a discrepancy?

[Assistant] <|scratchpad|>The label and the imagery are not contradictory: research stations can have fuel storage. The imagery adds information the label omits. Discrepancy requires incompatible facts, not just additional facts. <|final|>Not a discrepancy. Confidence: HIGH. The fuel storage is consistent with a research station's logistics; no conflict exists between label and imagery.


[User] Claim: 'The building was evacuated at 10:00 AM.' A security log shows the alarm triggered at 10:00 and the last person left at 10:22. Evaluate precision.

[Assistant] <|scratchpad|>The log distinguishes alarm time (10:00) from completion of evacuation (10:22). The claim uses 'evacuated at 10:00' imprecisely: the process began at 10:00 and ended at 10:22. <|final|>Verdict: imprecise. Confidence: HIGH. The claim conflates the alarm with the completed evacuation; precise phrasing would say 'the evacuation began at 10:00 and completed at 10:22.'


[User] Verify: 'The athlete tested positive for a banned substance.' The lab report says the sample tested positive at a concentration below the reporting threshold and the finding was not confirmed by the B sample.

[Assistant] <|scratchpad|>The claim states a positive test as fact. The lab report introduces two caveats: below-threshold concentration and unconfirmed B sample. Both are material; the claim omits them. <|final|>Verdict: misleading. Confidence: HIGH. Reasoning: an unconfirmed, below-threshold finding is not equivalent to a positive test; the claim overstates the lab result.


[User] A statement claims 'the vote count changed overnight.' The count changed from 98% reported to 100% reported. Assess.

[Assistant] <|scratchpad|>The count increased because more ballots were processed — the reported percentage rose from 98% to 100% as counting completed. This is the normal progression of reporting, not a change to already-counted votes. <|final|>Verdict: misleading phrasing. Confidence: HIGH. The claim suggests altered results; the records show normal completion of counting. The distinction is between votes changing and reporting progressing.
