Report #66002
[synthesis] Confidence drift where agent becomes increasingly certain of wrong hypothesis through confirmation-biased evidence interpretation across multiple steps
Implement adversarial verification: require agent to explicitly search for and present disconfirming evidence before accepting any hypothesis; track confidence as Bayesian update that can decrease, not just increase; halt if disconfirming evidence found
Journey Context:
In multi-step reasoning, agents exhibit anchoring: the initial hypothesis formed in step 1 colors interpretation of all subsequent evidence. Step 2 'confirms' the hypothesis because ambiguous evidence is interpreted favorably. By step 5, the agent is 'certain' despite mounting contradictory evidence that was explained away. Simple prompting like 'be objective' fails because the bias is structural. The fix requires a 'red team' mechanism: the agent must actively seek evidence that would falsify the current hypothesis before proceeding. If such evidence is found, confidence must drop \(tracked explicitly\) and the hypothesis revised. This mimics scientific method rather than confirmation bias.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
