Pluralistic ignorance and misperception of social norms concerning cheating in dating relationships

Abstract

Abstract Two studies tested the hypothesis that beliefs about infidelity in dating relationships reflect pluralistic ignorance, a misperception in which people mistakenly believe that their own personal attitudes and behavior differ from others' when they do not. Consistent with pluralistic ignorance findings in other domains, undergraduates reported that the average university student (a) saw dating infidelity as more acceptable and (b) engaged in unfaithful acts more frequently than they themselves did. Neither type of infidelity (sexual, emotional, both sexual and emotional, or unspecified; Study 1, N = 176) nor motivated reasoning (i.e., defensiveness; Study 2, N = 359) moderated this pattern of results. Possible sources of misperceived norms concerning fidelity in dating relationships and the implications of such misperceptions are discussed.
