Abstract: Extant monoracial identity frameworks fail to capture the experiences of biracial people, whose racial identity may depend on the social context. Biracial people can vary their racial identity, but the social consequences of context-dependent racial self-presentation remain underexplored. Five studies examined how contextual racial presentation among biracials is perceived by high status groups. White participants read vignettes describing a biracial person contextually presenting in an academic situation and evaluated the target's character and behavior. Asian/White or Black/White biracial students who contextually presented as monoracial (compared to biracial presentation) were evaluated more negatively because they were seen as less trustworthy. The effect of presenting as White was mediated by endorsement of stereotypes that biracial people are confused about their racial identity. The results suggest contextually choosing an identity carries social repercussions because it can activate explicit negative stereotypes about biracial people.
