Syllabus: How Do Attitudes Form and Change?
Compare behavior-induced change with the message-based explanation in the preceding experiment.
Why you’re reading it. Examine an account in which evaluation may follow action, while keeping alternative explanations visible.
A question to consider. Which added measure or comparison could help distinguish reducing discomfort from inferring an attitude from one's own behavior?
Why this reading
The experiment that made cognitive dissonance theory famous, and a model of how an experiment can produce a result that common sense would predict the other way. Participants who were paid one dollar to tell the next person that a tedious task had been enjoyable later rated the task as more enjoyable than those paid twenty dollars. The paper is short, the design is simple, and the inference from the design to the theory is exactly the thing a reader should learn to inspect.
Before you read
Know the theory being tested: dissonance is an uncomfortable state produced by holding inconsistent cognitions, and people reduce it by changing the cognition that is easiest to change. Here the inconsistency is between "the task was boring" and "I told someone it was interesting". A large payment justifies the lie; a small one does not, so something else has to give.
Know also what the competing prediction was. On a reinforcement account, the larger reward should produce the larger change.
Read for
- The design: what is manipulated, what is held constant, and what the dependent measure actually is.
- The logic that connects the result to the theory. What would the reinforcement account have predicted, and which version of that prediction does the result challenge?
- Details that a summary omits: the control group, the exact wording of the cover story, the size of the effect, and the number of participants.
- What the experiment does not establish. Is dissonance measured, or inferred from the pattern of ratings?
Consider afterwards
- Suppose the twenty-dollar participants simply paid less attention to what they were saying. Does that alternative explain the result, and how would you design a study to rule it out?
- The experiment shows an effect under one set of conditions. What has to be assumed to move from this result to a general theory of attitude change?
Editorial context
The result invites competing explanations of attitude change; dissonance is inferred rather than directly isolated by the ratings. Vaidis et al. (2024) tested an essay-based induced-compliance paradigm based on Croyle and Cooper, not a direct rerun of the one-dollar/twenty-dollar task. They did not find the predicted high-choice versus low-choice attitude difference, although counterattitudinal and neutral essays differed. This challenges the robustness of that paradigm without settling every claim made by dissonance theory.
