description Leon Festinger Overview
Conflicts between beliefs and behavior were a defining concern in Leon Festinger's research. The American social psychologist developed cognitive dissonance theory in 1957 to explain the discomfort associated with inconsistent ideas or actions. The theory examines how people respond to that tension, including by changing an attitude or finding a justification that makes a decision feel more consistent with their beliefs. Festinger's work is relevant to the study of attitude change, decision-making and persuasion, with applications in behavioral science and marketing research.
Its value lies in asking what happens after a person encounters a contradiction, rather than assuming that new information automatically changes a belief. For students of social psychology, it provides a way to investigate how people maintain a sense of consistency while navigating choices and competing commitments.
help Leon Festinger FAQ
What did Leon Festinger mean by cognitive dissonance?
Festinger used the term for psychological discomfort produced by inconsistent beliefs, actions, or evidence. His 1957 book A Theory of Cognitive Dissonance proposed that people are motivated to reduce that conflict by changing a belief, changing behavior, or rationalizing the inconsistency.
What happened in Festinger and Carlsmith's one-dollar experiment?
Participants performed a dull task and were then paid either $1 or $20 to tell another person that it was enjoyable. Those paid only $1 later rated the task more favorably, which the researchers interpreted as attitude change caused by insufficient external justification.
How did the failed prophecy in When Prophecy Fails support Festinger's theory?
Festinger and his colleagues observed a small group that expected extraterrestrials to rescue them before a catastrophic flood. When the prediction failed, strongly committed members increased their efforts to recruit others, helping inspire the idea that social support can preserve a disconfirmed belief.
What is Festinger's social comparison theory?
Festinger proposed in 1954 that people evaluate their opinions and abilities partly by comparing themselves with others. Comparisons are especially influential when no clear objective standard is available and the other person seems relevant or similar.
