Cognitive Dissonance

The Theory

Almost half a century ago social psychologist Leon Festinger developed the cognitive



dissonance theory (Festinger, 1957).  The theory has obviously stood the test of time in

that it is mentioned in most general and social psychology textbooks today.  The theory is

somewhat counterintuitive and, in fact, fits into a category of counterintuitive social

psychology theories sometimes referred to as action-opinion theories.  The fundamental

characteristic of action opinion theories is that they propose that actions can influence

subsequent beliefs and attitudes.  This is counterintuitive in that it would seem logical

that our actions are the result of our beliefs/attitudes, not the cause of them.  However, on

further examination these types of theories have great intuitive appeal in that the theories,

particularly cognitive dissonance, address the pervasive human tendency to rationalize.

Cognitive dissonance theory is based on three fundamental assumptions (see Figure 1).



1.

 

Humans are sensitive to inconsistencies between actions and beliefs.

 



According to the theory, we all recognize, at some level, when we are acting in a

way that is inconsistent with our beliefs/attitudes/opinions.  In effect, there is a

built in alarm that goes off when we notice such an inconsistency, whether we

like it or not.  For example, if you have a belief that it is wrong to cheat, yet you

find yourself cheating on a test, you will notice and be affected by this

inconsistency.



2.

 

Recognition of this inconsistency will cause dissonance, and will motivate an

individual to resolve the dissonance.

 



Once you recognize that you have violated one of your principles, according to

this theory, you won’t just say “oh well”.  You will feel some sort of mental

anguish about this.  The degree of dissonance, of course, will vary with the

importance of your belief/attitude/principle and with the degree of inconsistency

between your behavior and this belief.  In any case, according to the theory, the

greater the dissonance the more you will be motivated to resolve it.



3.

 

Dissonance will be resolved in one of three basic ways:

a)

 

Change beliefs

 



Perhaps the simplest way to resolve dissonance between actions and beliefs is

simply to change your beliefs.  You could, of course, just decide that cheating

is o.k.  This would take care of any dissonance. However, if the belief is

fundamental and important to you such a course of action is unlikely.

Moreover, our basic beliefs and attitudes are pretty stable, and people don’t

just go around changing basic beliefs/attitudes/opinions all the time, since we




2

rely a lot on our world view in predicting events and organizing our thoughts.

Therefore, though this is the simplest option for resolving dissonance it’s

probably not the most common.



b)

 

Change actions

 



A second option would be to make sure that you never do this action again.

Lord knows that guilt and anxiety can be motivators for changing behavior.

So, you may say to yourself that you will never cheat on a test again, and this

may aid in resolving the dissonance.  However, aversive conditioning (i.e.,

guilt/anxiety) can often be a pretty poor way of learning, especially if you can

train yourself not to feel these things.  Plus, you may really benefit in some

way from the action that’s inconsistent with your beliefs.  So, the trick would

be to get rid of this feeling without changing your beliefs or your actions, and

this leads us to the third, and probably most common, method of resolution.

c)

 

Change perception of action

 



A third and more complex method of resolution is to change the way you

view/remember/perceive your action.  In more colloquial terms, you would

“rationalize” your actions.  For example, you might decide that the test you

cheated on was for a dumb class that you didn’t need anyway.  Or you may

say to yourself that everyone cheats so why not you?  In other words, you

think about your action in a different manner or context so that it no longer

appears to be inconsistent with your actions.  If you reflect on this series of

mental gymnastics for a moment you will probably recognize why cognitive

dissonance has come to be so popular.  If you’re like me, you notice such

post-hoc reconceptualiztions (rationalizations) of behavior on the part of

others all the time, though it’s not so common to see it in one’s self.

The Experiment

There have been 100s, if not 1000s, of experiments that have examined cognitive

dissonance theory since the theorie’s inception, but the seminal experiment was published



3

in 1959 (Festinger & Carlsmith, 1959).  This experiment is very interesting viewed

within a psychological/historical context because it involved a direct test of a

“mentalistic” theory versus a behaviorist theory.  Cognitive dissonance theory was based

on abstract/internal/mental concepts, which were, of course, anathema to the behaviorists.

Festinger and Carlsmith set up an ingenious experiment which would allow for a direct

test of cognitive dissonance theory versus a behavioral/reinforcement theory.

In this experiment all participants were required to do what all would agree was a

boring task and then to tell another subject (who was actually a confederate of the

experimenter) that the task was exciting.  Half of the subjects were paid $1 to do this and

half were paid $20 (quite a bit of money in the 1950s).  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.
