We compared perceived cultural stereotypes of diverse groups varying by gender and ethnicity. Using a free-response procedure, we asked 627 U.S. undergraduates to generate 10 attributes for 1 of 17 groups: Asian Americans, Blacks, Latinos, Middle Eastern Americans, or Whites; men or women; or 10 gender-by-ethnic groups (e.g., Black men or Latina women). Based on intersectionality theory and social dominance theory, we developed and tested three hypotheses. First, consistent with the intersectionality hypothesis, gender-by-ethnic stereotypes contained unique elements that were not the result of adding gender stereotypes to ethnic stereotypes. Second, in support of an ethnicity hypothesis, stereotypes of ethnic groups were generally more similar to stereotypes of the men than of the women in each group. Third, a gender hypothesis postulated that stereotypes of men and women will be most similar to stereotypes of White men and White women, less similar to ethnic minority men and ethnic minority women, and least similar to Black men and Black women. This hypothesis was confirmed for target women, but results for target men were mixed. Collectively, our results contribute to research, theory, and practice by demonstrating that ethnic and gender stereotypes are complex and that the intersections of these social categories produce meaningful differences in the way groups are perceived.
