In three studies, we examined whether ingroup disparaging humor leads to greater stereotyping of the ingroup. First, in Study 1, (N = 101) university students were exposed to (a) ingroup disparaging humor, (b) neutral humor, or (c) ingroup disparaging nonhumorous text. Participants exposed to disparaging humor reported more stereotypic evaluations than those in the neutral humor or disparaging text condition. Study 2 (N = 167) replicated these findings with humor conditions (disparaging vs. neutral) and showed that ingroup identification moderated the effects of the type of humor. Low identifiers exposed to ingroup disparaging humor (vs. those in the control condition) reported a greater frequency of stereotypic evaluations, whereas the manipulation did not affect high identifiers. Finally, Study 3 (N = 153) also manipulated the source of the jokes. As in Study 2, we found an interaction effect showing that high identifiers were not affected by the manipulation, whereas for low identifiers disparaging humor increased stereotyping and led to more negative emotions toward the ingroup. No significant effects were found for source of the jokes. We discuss findings in terms of how the traditional pattern of humor facilitating outgroup stereotyping also seems to apply to ingroup stereotyping.
