“…Social norms—the unspoken rules of acceptable behavior—are strongly related to intergroup attitudes toward a variety of groups (Crandall, Eshleman, & O'Brien, 2002; Falomir‐Pichastor, Chatard, Selimbegovic, Nonan, & Mugny, 2013; Monteith, Deneen, & Toonan, 1996) and intergroup behaviors (Gabarrot, Falomir, & Mugny, 2009; Jetten, Spears, & Manstead, 1996), even among children (Nesdale & Dalton, 2011). In addition to predicting attitudes, social norms predict negative behaviors like insulting and derogating outgroup members (e.g., Amiot, Sansfaçon, & Louis, 2013; Amiot, Sansfaçon, & Louis, 2014). Given the importance of norms in predicting both behavior and attitudes toward outgroup members, we propose that perceptions of norms as accepting of prejudice in online gaming will in turn predict how people behave in this environment.…”
