We efficiently and rapidly categorize individuals into social groups (e.g., race, gender, age) based, in part, on visual cues of the face and body (Macrae & Quadflieg, 2010). Our social world, however, is occupied not just by individuals but also by individuals in groups. Extending person perception research to understand people or group perception, the present study examines bias in our judgments of large 100 person groups composed of Black and White faces. Specifically, participants judged 80 groups that varied in race ratio (20 Black:80 White-80 Black:20 White, in increments of 10) as either majority White or majority Black. Using these judgments, we calculated the point at which participants perceived groups to be equally Black and White (i.e., point of subjective equality, PSE). We hypothesized that individuals who were more politically conservative would over-estimate the number of Black compared to White individuals in groups (e.g., have higher PSEs), suggesting a threat response. This study is one of the first to examine race and people perception, with consequences for associations between racial bias and our perceptions of multi-racial groups.
