Cognitive Dissonance Theory Notes

Overview of Cognitive Dissonance Theory

  • Cognitive Dissonance: A theory developed by Leon Festinger that explores attitudes and behaviors, suggesting that inconsistency among beliefs or behaviors creates discomfort (dissonance).

  • Basic Premise: Individuals have a natural tendency to maintain consistent attitudes and behaviors. Deviating from them leads to psychological discomfort, prompting efforts to restore consistency.

Key Assumptions of the Theory

  • People are motivated to reduce discomfort caused by dissonance.

  • Dissonance arises when behaviors contradict beliefs or attitudes without coercion.

    • Example: If someone does something they don't believe in, as opposed to being forced to do it, they'll experience dissonance.

Methods of Dissonance Reduction

  1. Change Behavior: Alter the behavior to align with beliefs.

    • Example: Change from eating unhealthy food to sticking to a diet.

  2. Change Attitude: Adjust beliefs to match the behavior.

    • Example: Convince oneself that eating a treat is acceptable occasionally.

  3. Justification: Provide reasoning for the behavior to alleviate discomfort.

    • Example: Justifying a dietary break by planning more exercise.

  4. Ignore or Deny Conflict: Reject conflicting information that contradicts existing beliefs to avoid dissonance.

Festinger's Original Experiment

  • Study Description:

    • Participants performed a boring task (turning pegs) and were asked to lie about it for either $1 or $20.

    • Those paid $1 had no strong justification for lying (therefore experienced dissonance and altered their attitudes), while those paid $20 felt justified by the substantial incentive.

Conducting the Study

  • Prestudy Measurements: Participants evaluated their mood and cognitive dissonance before engaging in the task.

  • Task Design:

    • Participants either received a belief they thought to be true (low dissonance condition) or false (high dissonance condition) about a psychological myth.

    • They wrote a paragraph persuading others that the statement was true.

  • Poststudy Assessments:

    • Mood and belief measures post-task to evaluate changes in cognition and feelings of dissonance.

Findings and Observations

  • Dissonance Thermometer Results:

    • Participants in high dissonance conditions reported more feelings of discomfort than those in low dissonance conditions.

    • Observations indicated a trend toward reduced belief in the task across several weeks.

  • Surprise Measures:

    • Participants exhibited surprise levels indicating their familiarity and foundational beliefs about the myths.

    • Those unfamiliar with the myth reported higher surprise levels when they discovered it was false.

Conclusion of Study

  • Despite evidence of experienced dissonance, there was no significant belief change between the high and low dissonance conditions.

  • Task difficulty may explain reported discomfort rather than cognitive dissonance.

  • Further analysis is needed to clarify the relationship between cognitive dissonance and belief change outcomes in varying contexts.
