SELF-: AN ALTERNATIVE INTERPRETATION OF COGNITIVE DISSONANCE PHENOMENA1

DARYL J. BEM Carnegie Institute of Technology

A 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 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 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.
