3. Dissonance—when the behaviors and the beliefs do not match; they contradict one
another, which makes us feel uncomfortable. Not all dissonance is equal—we can
ignore some dissonance, yet other forms of dissonance lead to behavior change
a. Importantly, not all dissonance is created equally. Magnitude of dissonance
exists whereby some forms of incongruence produce greater discomfort than
others (Zimbardo, Ebbesen, & Maslach, 1977). This magnitude of dissonance
can be measured by three variables
i. Perceived importance—how significant is this behavior to you?
ii. Dissonance ratio—the proportion of incongruent beliefs held in relation to
the consonant beliefs
iii. Rationalize—justifying the dissonance; the ability to comfort yourself
when faced with dissonance
b. CDT argues that an individual selectively perceives various stimuli so as to
minimize dissonance
i. Selective exposure—actively avoiding information inconsistent with
established beliefs
ii. Selective attention—if you cannot avoid the situation, attending (or
listening) only to the information which pertains to those beliefs
iii. Selective interpretation—deciphering ambiguous information to force it
to match your established beliefs
iv. Selective retention—only storing inconsistent information for as long as
necessary
D. Persuasion through dissonance
1. The theory is useful in a variety of outlets, such as advertising and organizational
commitment
3. Creating too much dissonance can lead to the receiver of the message disliking
you rather than changing behaviors
