Cognitive Dissonance Theory Overview

Cognitive Dissonance Theory

• Origins:

  • Proposed by Festinger after observing rumors following a significant earthquake in 1954 and cult behavior concerning predictions of a flood.

  • Rumors were linked to fear and anxiety, leading to cognitive justification for beliefs.

  • Cognitive dissonance arises when individuals experience two conflicting cognitions.

• Theoretical Concepts:

  • Dissonance stems from cognitive inconsistency (consonant vs. dissonant vs. irrelevant elements).

  • Calculating Dissonance: $D^* = D / (D + C)$

  • $D^*$: magnitude of dissonance

  • $D$: sum of dissonant elements

  • $C$: sum of consonant elements.

  • Reducing dissonance often involves changing dissonant beliefs or adding consonant beliefs.

• Reduction Strategies:

  • Cognitive reframing to lower perceived tension.

  • Adding consonant cognitions to alleviate discomfort from dissonance.

• Early Research:

  • Induced Compliance: Festinger & Carlsmith (1959) demonstrated how insufficient justification affects attitude alignment.

  • Free Choice Paradigm: Brehm’s studies showed attitude change based on choice difficulty.

• Reactance Theory:

  • Explains behavioral resistance when perceived freedom is threatened. It leads to motivations to restore threatened freedoms, through either direct or indirect actions.

• Self-consistency Theory (Aronson):

  • Merges self-concept with cognitive dissonance; dissonance arises when actions conflict with self-image.

• Self-Perception Theory (Bem):

  • Proposes that individuals assess their attitudes based on observed behavior rather than internal consistency.

• Self-affirmation Theory (Steele):

  • Discomfort arises from perceived threats to self-integrity rather than cognitive inconsistencies.

• Critiques:

  • Discrepancies in findings; some individuals do not demonstrate dissonance effects, leading to revisions of the theory.
