The present study sought to examine the role of sexual identity and exposure to stereotypes of feminism on women's self-identification as a feminist, endorsement of feminist attitudes, and intention to engage in collective action. Participants (N = 312; all women) disclosed their sexual identity as either heterosexual or non-heterosexual (sexual minority) and were randomly assigned to one of three conditions: exposure to positive stereotypes of feminists, to negative stereotypes of feminists, control condition (no exposure to stereotypes). Results showed stark differences between heterosexual and sexual minority women, with sexual minority women scoring significantly higher on self-identification as feminist, feminist attitudes, and collective action intentions. Exposure to positive stereotypes of feminists increased feminist self-identification regardless of sexual identity. Exposure to negative stereotypes reduced selfidentification with feminism, and lower identification mediated the path between negative stereotyping and collective action. Implications of these findings for the advancement of women's rights movements are discussed.
