ABSTRACT Heteronormativity is a culturally embedded system defining acceptable identities and behaviors in romantic relationships. Recent literature has suggested that heteronormativity is strongly associated with political attitudes, personality characteristics such as tolerance of ambiguity, and key demographic variables such as gender and sexual orientation. However, interactions between gender and other factors have not been thoroughly explored as predictors of heteronormative attitude and beliefs. The current study (N = 306) expands the understanding of predictors of heteronormativity, particularly as they interact with gender. In the current study, higher education was associated with lower heteronormativity among women, but not among men, and expressiveness was associated with lower heteronormativity among men, but not among women. Finally, a 3-way interaction showed that the relationship between education and heteronormativity for men (but not women) depended on trait expressiveness. Future studies are recommended, including observation of changes in heteronormativity over time and exploration of mechanisms that reinforce or reduce heteronormativity.
