Cognitive Dissonance Theory
Leon Festinger
INTRODUCTION
-
Leon Festinger developed the cognitive dissonance theory (Festinger, 1957)
-
Dissonance occurs when a person perceives a logical inconsistency in their beliefs, when one idea implies the opposite of another.
-
Inconsistency among beliefs or behaviors will cause an uncomfortable psychological tension.
-
The dissonance might be experienced as guilt, anger, frustration, or even embarrassment.
-
This will lead people to change their beliefs to fit their actual behavior, rather than the other way around, as popular wisdom may suggest.
ASSUMPTIONS
-
Humans are sensitive to inconsistencies between actions and beliefs.
-
Recognition of this inconsistency will cause dissonance, and will motivate an individual to resolve the dissonance.
-
Dissonance will be resolved in one of three basic ways:
a. Change beliefs
b. Change actions
c. Change perception of action
COGNITIVE DISSONANCE MODEL
The classic experiment by Festinger & Carlsmith, 1959 (Boring task experiment)
In this experiment all participants were required to do what all would agree was a boring task and then to tell another subject that the task was exciting. Half of the subjects were paid $1 to do this and half were paid $20. Following this, all subjects were asked to rate how much they liked the boring task. This latter measure served as the experimental criterion/the dependent measure. According to behaviorist/reinforcement theory, those who were paid $20 should like the task more because they would associate the payment with the task. Cognitive dissonance theory, on the other hand, would predict that those who were paid $1 would feel the most dissonance since they had to carry out a boring task and lie to an experimenter, all for only 1$. This would create dissonance between the belief that they were not stupid or evil, and the action which is that they carried out a boring tasked and lied for only a dollar (see Figure 2). Therefore, dissonance theory would predict that those in the $1 group would be more motivated to resolve their dissonance by reconceptualizing/rationalizing their actions. They would form the belief that the boring task was, in fact, pretty fun. As you might suspect, Festinger’s prediction, that those in the $1 would like the task more, proved to be correct.
