Cognitive Dissonance Theory Leon Festinger 1957
1. Overview of Theory • Cognitive elements - defined bits of knowledge or opinions or beliefs • Basic Relations • Consonant • Dissonant • Irrelevant
Assumptions • Psychological tension to reduce dissonance • We not only reduce it, we avoid situations that increase it • Dissonance increases when alternatives contain attractive features • Increased dissonance, increased pressure • Pressure = importance & # of elements
2. Reducing Dissonance • Change one of the elements • Seek evidence to discredit • Change importance of cognitiones • Seek confirmatory evidence
3. Dissonance & Beliefs(future) Conditions for dissonance arousal • Firm conviction • Public commitment • Clear confirmation/disconfirmation of conviction • Unequivocal disconfirmation • Social support available
4. Dissonance & Decisions • Degree of dissonance • Important to person • Mix of attractive & unattractive features • Dissimilar attributes but similar desirability • Reducing Dissonance • Change Decision • Increase attractiveness of chosen • Decrease attractiveness of unchosen • Seek confirming information • View consequences as the same
5. Insufficient Justification • Definition - a cognition following from another that can not be justified • Boring task example • Creates powerful dissonance
6. When is dissonance aroused? • Reasons for not being dissonant • Blame environment • Blame others • Dissonance aroused • “I willing caused it” • “It was a significant decision” • ROTC example
7. Self Concept • How do you explain self-fulfilling prophecy? • We have a vested interest in failure
8. Criticisms • Prediction Problems - How will dissonance be reduced? • Can the theory be proven or disproven? (Falsifiability) • Quantifiable?
