Cognitive Dissonance

Finding
Festinger demonstrated that contradictory cognitions produce psychological discomfort. The classic 20 experiment: subjects paid 20, because $1 was insufficient justification. Dissonance is proportional to the importance of the conflicting cognitions. Resolution typically prefers ease (attitude change) over truth (acknowledging the conflict). Cooper (2007) provides comprehensive review.
Pattern Mapping
Alignment — Dissonance IS felt misalignment between beliefs, or between belief and action. The discomfort is the signal that alignment has been violated.
Honesty — Resolution prefers ease over truth. Rather than acknowledging the contradiction, the system changes the easier cognition. This is structural dishonesty in the service of coherence.
Proportion — Dissonance is proportional to the importance and number of conflicting cognitions. Small contradictions produce small discomfort; large ones produce large.
Connections
- Heart and Cardiac Valves — valve regurgitation is physical misalignment; dissonance is cognitive misalignment — both produce degradation
- Wound Healing — dissonance resolution that prefers ease is like chronic inflammation: failure to complete the repair process honestly
- Conway Memory and the Self — both show that the cognitive system prioritizes coherence over correspondence
- Apoptosis in Development — healthy systems remove what does not function; dissonance resolution often preserves the dysfunctional element
- Narcissus — Narcissus resolves his dissonance (this cannot be me / this is beautiful) by denial rather than honest recognition
Status
Among the most replicated findings in social psychology. Festinger (1957) foundational. Cooper (2007) reviews. No serious controversy on core effect.
The mapping to the five properties is this project’s structural interpretation.
