INTRODUCTION

English translation pending.

CORE DEFINITION

From the Lushi Chunqiu: a man who suspected his neighbor of stealing an axe found that every word and movement of the neighbor looked like a thief's, and after recovering the axe found that the same behavior looked entirely normal. The parable demonstrates how a prior belief shapes perception rather than merely biasing the conclusion. The qualification is that the distortion is involuntary, so self-awareness alone does not remove it. Its remedy is external evidence, the recovered axe.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Suspicion check: ask whether you formed the hypothesis before or after observing the behavior. - Disconfirming search: actively look for evidence that would show the suspicion is mistaken. - Evidence anchor: withhold judgment until the equivalent of the lost axe is found.

anchor

Anchor fast decisions

Once a hypothesis is formed, ambiguous behavior is interpreted in its favor, because the same action supports many readings and the prior selects among them. The interpretation then feels like confirmation, which strengthens the prior further. Only evidence external to the observer's interpretation, such as finding the axe, breaks the cycle, since internal reflection uses the same biased filter.
