There is evidence that men misinterpret the behavior of females as indicating sexual interest when no such message is intended (Abbey, 1982). The present study was designed to assess the accuracy with which men and women can predict the opinions of the opposite sex. Forty-four men and 81 women in introductory psychology classes were shown one of rwo slides. One slide represented a female model wearing 'conservative' clothing while the other slide depicted the model in sexually provocative clothing. Subjects were asked to complete a questionnaire indicating impressions of the female and also to estimate the opinions of a typical member of the opposite sex. The results were consistent with studies describing a generally negative bias toward women wearing provocative clothing (Edmocds & Cahoon, 1986). While the model in the sexy-clothing condition was judged to be more attractive and sexually appealing to men. she was viewed more negatively with respect to age of first intercourse, sexual teasing, extent of sexual activity, using sex for personal gain, and faithfulness in marriage. The sexy model was also viewed as more likely to be raped or robbed, a finding previously reported by Edmonds and Cahoon (1986). Male and female raters tended to agree in their judgments although there was n tendency for the men to rate the model more positively than the women. Differences were found when men and women attempted to predict the actual opinions of the opposite sex, with women making significantly more and larger errors (Fl,ao = 29.97, p < ,001). Examination of the items indicated that women assumed that men would view the model more negatively than was actually the case. Men were also asked to indicate the likelihood chat they would rape the model if they could do so with impunity. While 7.6% of the male subjects endorsed the possibility of raping the conservatively dressed model, women predicted that 36.3% of the men would respond positively. Corresponding percentages for the sexually provocative model were 38.8% for men and 61.6% for women. Apparently, in addition to a tendency for men to view the world in sexual terms (Abbey, 1982), there is a corresponding tendency for women to misjudge male sexual attitudes and especially men's motivation to
