Small groups lead, big groups control: Perceptions of numerical group size, power, and status across development

Abstract

Participants (N = 384 three- to ten-year-olds; 51% girls, 49% boys; 73% White, 18% multiracial/other, 5% Asian, and 3% Black; N = 610 adults) saw depictions of 20 individuals split into two social groups (1:19; 2:18; 5:15; or 8:12 per group) and selected which group was "in charge" (Experiment 1), "the leader" (Experiment 2), or likely to "get the stuff" (resources) in a conflict (Experiment 3). Whereas participants across ages predicted the larger group would "get the stuff," a tendency to view smaller groups as "in charge" and "the leader" strengthened with age and when the smaller group was rarer. These findings suggest the perceived relation between numerical group size and hierarchy is flexible and inform theory regarding the developmental trajectories of reasoning about power and status.
