Back to the Future of Dissonance Theory: Cognitive Consistency as a Core Motive

In his theory of cognitive dissonance, Festinger (1957) described cognitive consistency as a psychological need that is as basic as hunger and thirst. Over the past decades, however, the idea of cognitive consistency as a core motive has been replaced by an increasingly narrow focus on dissonance-related changes in attitudes and alternative accounts that attribute such changes to mechanisms of ego-defense. The current article aims at reviving the idea of cognitive consistency as a core motive, arguing that inconsistency serves as an epistemic cue for errors in one's system of beliefs. Because inconsistency can often be resolved in multiple ways, motivated reasoning can bias processes of inconsistency resolution toward desired conclusions, although motivated distortions are constrained by the need for cognitive consistency. The ubiquity of consistency processes is illustrated through its role in various instances of threat-compensation (e.g., victim derogation, self-verification, system justification) and the insights that can be gained from reconceptualizing various social psychological phenomena in terms of cognitive consistency (e.g., prejudice-related belief systems, dispositional inference, stability of first impressions).
