Looming large in others' eyes: racial stereotypes illuminate dual adaptations for representing threat versus prestige as physical size

Abstract

We hypothesize that, paralleling the evolution of human hierarchies from social structures based on dominance to those based on prestige, adaptations for representing status are derived from those for representing relative fighting capacity. Because both violence and status are important adaptive challenges, the mind contains the ancestral representational system as well as the derived system. When the two representational tasks conflict, owing to the exigent nature of potential violence, the former should take precedence over the latter. Indeed, separate literatures indicate that, despite the fact that threatening traits are generally deleterious to prestige, both threatening individuals and high-status individuals are conceptually represented as physically large. We investigated the interplay between size-based representations of threat versus prestige by examining racial danger stereotypes. In three studies, we demonstrate that (a) judgments of status only positively correlate with envisioned body size for members of groups stereotyped as safe, (b) group-based inferences of interpersonal threat are mediated by representations of physical size, (c) controlling for perceived threatening aggressiveness reduces or reverses non-positive correlations between status and size, and (d) individuating information about relative threat or status attenuates the influence of group danger stereotypes. These results support our proposal that ancestral threat-representation mechanisms and derived mechanisms for representing social rank coexist – and sometimes compete – in the mind.
