Fickle Prosociality: How Violence against LGBTQ+ People Motivates Prosocial Mass Attitudes toward LGBTQ+ Group Members By Marcel F. Roman, Harvard University and Jack Thompson, University of Leeds We present a Fickle Prosocial Violence Response Model to explain how indirect exposure to civilian-perpetrated violence against marginalized minority groups motivates prosocial attitudes toward victimized groups. Although the mass public may not sympathize with marginalized groups, they may adopt prosocial attitudes toward marginalized groups subject to civilian-perpetrated violence if the violence is salient and perceptibly illegitimate.
