Psychological Review 1967, Vol. 74, No. 3, 183-200 SELF-PERCEPTION: AN ALTERNATIVE INTERPRETATION OF COGNITIVE DISSONANCE PHENOMENA1 DARYL J. BEM Carnegie Institute of Technology A theory of self-perception is proposed to provide an alternative in- terpretation for several of the major phenomena embraced by Fest- inger's theory of cognitive dissonance and to explicate some of the secondary patterns of data that have appeared in dissonance experi- ments. It is suggested that the attitude statements which comprise the major dependent variables in dissonance experiments may be regarded as interpersonal judgments in which the observer and the observed happen to be the same individual and that it is unnecessary to postu- late an aversive motivational drive toward consistency to account for the attitude change phenomena observed. Supporting experiments are presented, and metatheoretical contrasts between the "radical" be- havioral approach utilized and the phenomenological approach typi- fied by dissonance theory are discussed. If a person holds two cognitions that ducted within the framework of dis- are inconsistent with one another, he sonance theory; and, in the 5 years will experience the pressure of an since the appearance of their book, aversive motivational state called cog- every major social-psychological jour- nitive dissonance, a pressure which he nal has averaged at least one article will seek to remove, among other ways, per issue probing some prediction "de- by altering one of the two "dissonant" rived" from the basic propositions of cognitions.
