Three Ways to Reduce
Dissonance
1. Change behavior
2. Justify behavior by changing one of
the dissonant cognitions
3. Justify behavior by adding new
cognitions

How We Reduce Cognitive Dissonance
There are three basic ways of reducing dissonance: change your behavior, change your
cognition, or add a new cognition.

Self-Affirmation
• Bolster the self-concept
• Reducing dissonance by adding a
cognition about other positive
attributes
– E.g., smoker who fails to quit
• Not very smart of me to be smoking, but,
I’m really a very good mathematician!

Teenagers who smoke usually justify their actions with such cognitions as “Smoking is
cool”; “I want to be like my friends”; “in movies, everyone smokes”; “I’m healthy; nothing
is going to happen to me”; or “adults are always on my back about stuff I do”

Why We Overestimate the Pain
of Disappointment
• Why does impact bias occur?
– Process of reducing dissonance is largely
unconscious

Self-Esteem and Cognitive
Dissonance
• High self-esteem
– Strive to keep behavior consonant with
view of self
• Work harder to reduce dissonance than
people with average self-esteem

chosen alternative and devaluating the
rejected alternatives.

Creating the Illusion of
Irrevocability

(irrevocable)

Creating the Illusion of
Irrevocability
• Lowballing
– An unscrupulous strategy whereby a
salesperson induces a customer to agree to
purchase a product at a very low cost,
subsequently claims it was an error, and
then raises the price.
– Frequently, the customer will agree to
make the purchase at the inflated price.

The Cheating Pyramid
Imagine two students taking an exam. Both are
tempted to cheat. Initially, their attitudes toward
cheating are almost identical, but then one
impulsively cheats and the other does not. Their
attitudes will then undergo predictable changes.

initiation, the more we will like the group we have just joined—even if it turns out to be a
dud. (Adapted from Aronson & Mills, 1959.)

The Psychology of Insufficient
Justification
• Example
– If you tell a friend that you like her ugly
dress very much, do you experience much
dissonance?
• Many thoughts are consonant (consistent)
with having told lie
– E.g., it is important not to cause pain to
people, not hurt feelings

Elliot Aronson | Timothy D. Wilson | Robin M. Akert
©2013 Pearson Education, Inc.
All Rights Reserved.
The Psychology of Insufficient
Justification
• Believing it is important not to cause
pain to people you like provides ample
external justification for having told
lie
External Justification
A reason or an explanation for dissonant personal
behavior that resides outside the individual. E.g., in
order to receive a large reward or avoid a severe
punishment.

Justification

something about oneself.

The Psychology of Insufficient
Justification
• If there is insufficient external
justification for counterattitudinal
advocacy, the attempt to reduce
dissonance may result in attitude
change!
Counterattitudinal Advocacy
Stating an opinion or attitude that runs counter to
one’s private belief or attitude.

• Students paid $20 for lying—for saying
that the tasks had been enjoyable

view of self (honest person) & behavior
(lying)
– Lied because was paid to do so

Punishment and
Self-Persuasion
• If threat of punishment for engaging in
a forbidden behavior is severe
– There is sufficient external justification for
refraining from behavior

justification
• Change attitudes via self-persuasion

– The dissonance aroused when individuals
lack sufficient external justification for
having resisted a desired activity or object,

Figure 6.4
The Forbidden Toy Experiment
Children who had received a threat of mild punishment were far less likely to play with a
forbidden toy (orange bar) than children who had received a threat of severe punishment
(blue bar). Those given a mild threat had to provide their own justification by devaluing
the attractiveness of the toy (“I didn’t want to play with it anyhow”). The
resulting self-persuasion lasted for weeks. (Based on data in Freedman, 1965.)

Figure 6.5
External versus Internal Justification
As this graphic summarizes, insufficient punishment or reward leads to self-justification,
which in turn leads to self-persuasion and lasting change. Larger rewards or punishments
may produce temporary compliance, which rarely lasts.

The Hypocrisy Paradigm
• Induce hypocrisy
– Make person aware of conflict between
• Attitudes
• Behavior
– Hypocrisy creates dissonance
– Reduce dissonance by changing behavior

condoms

Figure 6.6
The Hypocrisy Paradigm
People who are made mindful of their hypocrisy (blue bars)—in this study, being made
aware of the discrepancy between knowing that condoms prevent AIDS and other STDs
but not using condoms themselves—begin to practice what they preach. Here, more of
them bought condoms, buying more condoms than did students in other conditions—
those who were simply given information about the dangers of AIDS, or who promised to
buy them, or who were made aware that they weren’t using them. (Adapted from Stone,
Aronson, Crain, Winslow, & Fried, 1994.)

condoms than students in any of the
other conditions.

Justifying Acts of Kindness
• Dissonance theory predicts that when
we dislike someone, if we do them a
favor, we will like them more
– Behavior is dissonant with attitude
– Change attitude about person to resolve

The Justification of Kindness
If we have done someone a personal favor (blue bar), we are likely to feel more
positively toward that person than if we don’t do the favor (orange bar) or do the favor
because of an impersonal request (yellow bar). (Based on data in Jecker & Landy, 1969.)
