“I am (oppressed), therefore I see”: Multiple stigmatized identities predict belief in generalized prejudice and intraminority coalition

Integrating lay theory of generalized prejudice (LTGP) and intersectionality frameworks, the present research demonstrated that, across four samples (N = 7,121), people with a greater number of stigmatized identities (based on race/ethnicity, gender, and sexual orientation) endorsed LTGP more strongly, perceived greater similarities across marginalized groups, and ultimately indicated stronger support for intraminority coalitions (Studies 1–3) and specifically stronger policy support for low-SES people (Study 3). Notably, multiply stigmatized people (especially those with three stigmatized identities) endorsed LTGP and intraminority coalitions more strongly than did singly stigmatized and non-stigmatized people, who did not significantly differ from each other on these outcomes. Together, these findings highlight the importance of intersectionality in understanding intraminority relations and contribute to coalition-building efforts across oppressed groups.
