Mapping principal dimensions of prejudice in the United States.

Research is often guided by maps of elementary dimensions, such as core traits, foundations of morality, and principal stereotype dimensions. Yet, there is no comprehensive map of prejudice dimensions. A major limiter of developing a prejudice map is the ad hoc sampling of target groups. We used a broad and largely theory-agnostic selection of groups to derive a map of principal dimensions of expressed prejudice in contemporary American society. Across a series of exploratory and confirmatory studies, we found three principal factors: Prejudice against marginalized groups, prejudice against privileged/conservative groups, and prejudice against unconventional groups (with some inverse loadings for conservative groups). We documented distinct correlates for each factor, in terms of social identifications, perceived threats, personality, and behavioral manifestations. We discuss how the current map integrates several lines of research, and point to novel and underexplored insights about prejudice. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
