Abstract

Across 6 studies, factors signaling potential vulnerability to harm produced a bias toward outgroup categorization-a tendency to categorize unfamiliar others as members of an outgroup rather than as members of one's ingroup. Studies 1 through 4 demonstrated that White participants were more likely to categorize targets as Black (as opposed to White) when those targets displayed cues heuristically associated with threat (masculinity, movement toward the perceiver, and facial expressions of anger). In Study 5, White participants who felt chronically vulnerable to interpersonal threats responded to a fear manipulation by categorizing threatening (angry) faces as Black rather than White. Study 6 extended these findings to a minimal group paradigm, in which participants who felt chronically vulnerable to interpersonal threats categorized threatening (masculine) targets as outgroup members. Together, findings indicate that ecologically relevant threat cues within both the target and the perceiver interact to bias the way people initially parse the social world into ingroup vs. outgroup. Findings support a threat-based framework for intergroup psychology.
