The presence of non-humans in media narratives - for example, in the supernatural genre - may make salient that we are all human. According to the common ingroup identity model, the human superordinate category should influence attitudes toward lower level outgroups. The present study examines this in the context of ethnic outgroups, specifically African Americans. Similarity of supernatural villains to humans was manipulated to influence whether "human" was a relevant superordinate group. Additionally, character race was varied to understand the influence of group diversity cues. Consistent with the common ingroup identity model, exposure to a Black human character fighting non-humans reduces prejudice toward African Americans, and this reduced prejudice generalizes to other minority groups. Results suggest a complex relationship between exposure to supernatural villains and diversity cues on attitudinal outcomes, with identity as human as one possible mechanism for reducing prejudicial attitudes.
