INTRODUCTION

English translation pending.

CORE DEFINITION

Proposed by Daryl Bem. The theory holds that when internal states are weak or ambiguous, people infer their attitudes and emotions the same way an outside observer would: by observing their own behavior and the conditions in which it occurs. It offers an alternative to cognitive dissonance theory, explaining attitude change without invoking an aversive drive. The theory is supported by studies showing that small incentives and prior acts shape reported attitudes.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Read yourself: when a preference feels unclear, look at what you actually do rather than what you say - Change by acting: start with a small behavior and let the attitude follow the action - Beware misattribution: check whether situational pressure rather than preference produced the behavior

anchor

Anchor fast decisions

Internal states are often too faint to read directly, so people use the same external cues an observer would use, with their own behavior being the most available. Behaving in a certain way therefore provides evidence about what one must believe, and the inferred attitude then guides later behavior. This creates a loop in which action and attitude reinforce each other without any need for discomfort.
