Cognitive Dissonance Lecture Notes

Introduction to Cognitive Dissonance

  • Origin: Term coined by Leon Festinger in 1957.
  • Definition: Cognitive dissonance refers to the mental discomfort experienced by a person who holds two or more contradictory beliefs, ideas, or values at the same time.

Key Concepts

  • Inconsistency: The core of cognitive dissonance is the presence of conflicting thoughts or beliefs.
  • Example: A smoker who recognizes that smoking is harmful yet continues to smoke.

Ways to Resolve Cognitive Dissonance

  1. Change Cognition: Altering one of the conflicting thoughts.
    • Example: Believing "smoking is not harmful" instead of recognizing it as unhealthy.
  2. Change Behavior: Eliminating the behavior that causes dissonance.
    • Example: Quitting smoking if acknowledging it's harmful.
  3. Add New Cognitions: Introducing new thoughts that justify or rationalize the inconsistency.
    • Example: "I smoke, but I also eat healthily and exercise."
  4. Trivialize the Inconsistency: Minimizing the significance of the conflicting beliefs.
    • Example: "Smoking is unhealthy, but I don't care."

Importance of Resolving Dissonance

  • Mental Comfort: Dissonance is uncomfortable and restoring consistency provides relief.
  • Understanding the World: A consistent viewpoint aids in comprehending reality.
  • Physical Discomfort: Dissonance can cause actual physical tension and discomfort.

Factors Influencing Dissonance Resolution

  • Perceived Choice: Feeling that one had a choice in creating the inconsistency can heighten dissonance.
    • Example: Writing an essay against personal beliefs by choice creates more dissonance than being forced to do so.
  • Aversive Consequences: Belief that inconsistency will result in negative outcomes increases the drive to resolve it.
    • Example: Believing an essay supporting tuition increase will lead to actual tuition hikes.

Conclusion

  • Understanding cognitive dissonance involves recognizing how and why people seek to resolve inconsistencies in their beliefs and actions.
  • Cognitive dissonance is a driving force behind actions aimed at restoring mental consistency and comfort.
