“…Social stratification can be found to varying degrees wherever humans congregate (Barkow, 1989;Hogan, 1983;Hogan & Hogan, 1991). For example, social hierarchies form rapidly in leaderless group discussions (Bass, 1954), possibly even at first glance (Kalma, 1991). Hierarchy formation has been documented in the free play of children (Hawley, 1999); in the social ecologies of early, middle, and late adolescents (Fournier, 2009); and in the fraternities, sororities, and dormitories of both male and female university students (Anderson et al, 2001;Harms et al, 2007).…”
