Subject: Who Stereotypes Less Favorably?: Adolescent Self-Reported Gender Typicality and Stereotypes about Gender Abstract: Gender is one aspect of identity that becomes salient during adolescence. Consequently, adolescents assess how typical for their gender they feel, as well as how they stereotype members of their gender in and out group. Past findings disagree on whether or not how much adolescents feel like a “typical” boy or girl (i.e. gender typicality) is related to positive in-group and negative out-group stereotypes. The mixed findings may in part reflect past studies’ use of a difference score between positive gender in-group and negative gender out-group stereotype endorsement. To counter this, the current study uses separate linear regression analyses to investigate how gender typicality is related to positive gender in-group and negative gender out-group stereotypes respectively, in an ethnically diverse sample of adolescents (N=4,613; 41% Latinx, 16% Black, 26% White, 17% Asian). Preliminary findings suggest that gender typicality is endorsing positive gender in-group stereotypes. Analyses also reveal a novel finding: Youth reporting less gender typicality endorse more *negative *stereotypes about the gender out-group compared to youth who report feeling more gender typical.
