Summary	The Collective Narcissism Scale, introduced by Agnieszka Golec de Zavala and colleagues in 2009, measures an emotional investment in an unrealistic belief about an in-group's greatness coupled with a demand that this greatness be recognized by others. Unlike secure group identification, collective narcissism is defensive and contingent on external validation, and it predicts intergroup hostility, perceived threat, prejudice, conspiracy belief, and support for aggression toward out-groups. The scale is widely applied to national identity, where it distinguishes a grandiose, grievance-driven nationalism from ordinary patriotism or in-group satisfaction.	The Blatant Dehumanization Scale, also called the Ascent of Man measure, captures the willingness to overtly deny full humanity to an out-group. Developed by Nour Kteily, Emile Bruneau, Adam Waytz, and Sarah Cotterill in 2015, it uses the iconic evolutionary image of a creature progressing from ape to upright human and asks respondents to rate, on a slider from zero to one hundred, how evolved different social groups are. The gap between how human respondents rate their own group and how human they rate an out-group is a strikingly direct, robust predictor of hostility, support for coercive policies, and aggression that goes beyond ordinary dislike.
