CORE DEFINITION
Identified by Charlie Munger as one of the main psychological tendencies causing human misjudgment. The core claim is that the mind treats co-occurrence as evidence of connection, so pleasant or unpleasant feelings attached to one stimulus transfer to whatever is paired with it. The key qualification is that the transfer happens below awareness and therefore feels like direct perception rather than inference, which is why the resulting judgment is defended as objective. Munger traced the mechanism to conditioning and cited advertising, brand names, and the Persian Messenger Syndrome as everyday expressions.
SCAFFOLDING EFFECT
Reduce cognitive load
- Emotion tracing: ask whether a strong reaction comes from present facts or from an old pairing - Blind scoring: hide brand and personal names, then rate the same options again - Reverse evidence: force yourself to find one negative fact about the option you like
Anchor fast decisions
The mind economizes on computation by treating co-occurrence as evidence of connection, then attaching an emotional reaction directly to the paired stimulus through conditioning. Because this transfer runs below awareness, the resulting like or dislike feels like a direct reading of the object rather than a residue of past pairing. The judgment is rationalized after the fact to fit the feeling, so the person experiences bias as clear-eyed observation.
