Positive intergroup contact, under some conditions, can undermine the interest of members of both socially disadvantaged and advantaged groups to act for equality. However, little is known about whether similar effects appear in a unique form of intergroup relations, gender relations. In two correlational studies and two experiments, we investigated the relationships among quality of contact, perceived discrimination, fusion with the feminist movement, and willingness to engage in collective action for women’s rights. For women (Study 1a), positive contact with men was associated with less perceived discrimination, less fusion, and less collective action. For men (Study 1b), the relationships were in the opposite direction. Studies 2a and 2b revealed that recalling experiences of gender discrimination nullified the effects of contact for both women and men as compared to a control condition. Thus, when discrimination is not explicitly recognized, positive contact might have sedative effects on women, but mobilizing effects on men.
