Is Essentialism Essential? Reducing Homonegative Prejudice by Targeting Diverse Sexual Orientation Beliefs

We conducted an experiment to assess whether targeting multiple beliefs about sexual orientation (SO) may be more effective in reducing homonegativity than focusing only on beliefs about its biogenetic origins. Participants (116 women, 85 men) were randomly assigned to one of three treatment conditions or a control condition. Those in the treatment conditions read essays summarizing: (1) research suggesting SO has biogenetic origins, (2) research suggesting SO is socially constructed and refuting beliefs about the discreteness, homogeneity, and informativeness of SO categories; or (3) research suggesting SO is biogenetic and research suggesting SO categories are socially constructed and not necessarily discrete, homogenous, or informative. We predicted participants in the conditions that targeted multiple beliefs related to the social construction of SO, not just its biogenetic origins, would exhibit the strongest reductions in beliefs about the discreteness, homogeneity, and informativeness of SO categories, and in homonegativity. We also predicted these participants would exhibit the greatest increases in support for gay and lesbian civil rights. We observed hypothesized shifts in SO beliefs across all experimental conditions. While there was a small main effect of time on homonegative prejudice, there was no main effect of condition and no changes in support for gay and lesbian civil rights. However, post hoc analyses suggested the two conditions addressing social constructionist beliefs accounted for most of the observed prejudice reduction. Implications for more comprehensive educational and social interventions designed to promote social justice for sexual minorities are discussed.
