Lay Theories of Gender Influence Support for Women and Transgender People's Legal Rights

Essentialism-the belief that differences between groups of people are biologically based and unchangeable-is strongly associated with prejudice toward a variety of social groups. The present work examines how gender essentialism shapes support for the rights of two marginalized gender groups: women and transgender people. Study 1 provides correlational evidence that endorsement of gender essentialism is a robust predictor of people's opposition to both women's and transgender people's rights, over and above other individual difference measures. Studies 2 and 3 provide evidence that exposure to anti-essentialist messages about gender indirectly increases the support for women's and transgender people's rights. Study 4 examines the underlying psychological process, showing that gender essentialism reduction indirectly increases the support for women's and transgender people's rights through prejudice. Implications for research on lay theories and transgender people are discussed.
