Affiliation with certain groups allows to simultaneously satisfy two competing needs: the need to be moderately different from others and the need to belong. We propose that the feminist movement, that has been turning towards individualistic goals based on individual empowerment, may be one of such groups for women. In three studies we examined the relationship between self-uniqueness and women's support for collective action and structural measures (i.e. sex quotas) promoted by the feminist movement. A first correlational study indicated that self-uniqueness need is positively associated with willingness to participate in collective action for gender justice generally, but not with support for sex quotas. Consistently, two experimental studies (Studies 2-3) found that priming self-uniqueness increases collective action intentions, but not quota support. Study 3 also showed that the effect of self-uniqueness on collective action intentions for gender justice may be mediated by greater perceptions of personal discrimination for being a woman and fusion with the feminist movement. These results suggest that appeals to self-uniqueness may attract women to the feminist movement but do not guarantee support for concrete collective measures against gender inequality.
