Recent work has established that groups can reduce dissonance by providing consonant cognitions, normative support, or an opportunity to diffuse responsibility for counterattitudinal behavior. Adopting a social identity framework, the current research comprised 2 studies examining metaconsistency, which was proposed to underlie these disparate explanations for the effect of social support. In Study 1 (N equals 121), participants performed a counterattitudinal behavior with or without attitude and behavior support. As expected, congruence between the participants' attitude–behavior consistency and another's attitude–behavior consistency reduced attitude change. Study 2 (N equals 69) replicated the results of Study 1; in addition, metaconsistency influenced participants' perceptions of their own attitude–behavior consistency. The implications of metaconsistency for other contemporary perspectives of dissonance theory are discussed.
