概要	This measure assesses citizens' willingness to endorse violence against political opponents, a key indicator of democratic fragility. Nathan Kalmoe and Lilliana Mason's research, synthesized in Radical American Partisanship (2022), maps a continuum of violent partisan hostility from wishing harm on the other side to endorsing lethal attacks, using representative surveys and embedded behavioral experiments. Because such attitudes are rare and the items are extreme, the measure has prompted vigorous methodological debate, exemplified by Westwood and colleagues' demonstration that inattentive responding and item design can substantially inflate apparent support, making bias correction central to credible estimates.	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.
