A popular contemporary meme involves the social acceptability of “punching Nazis.” This phenomenon raises the question: what characteristics make a group or member of a group more or less “punch-able”? More broadly, what group attributes yield support for physical violence against them? In this study, we build on the extant psychology literature on intergroup processes to look at what leads individuals to find physical violence against a group acceptable, and if the factors that lead to such acceptance differ from those that lead to sheer affective intolerance. We use two experimental tasks to test expectations built on prominent theories. In a “real-world rating task,” participants evaluated a series of real-world groups and individuals with varying characteristics such as race, ideology, intelligence, warmth, and tendency toward violence. Also, in a conjoint experiment, participants chose between two groups in terms of which they would support being punched, as various attributes were manipulated such as race, expressed ideological values, partisanship, income, tendency toward violence, and being described as disgusting or threatening. We find consistent support for effects of political alignment (particularly, expressed ideological values related to dominance) and perceived tendency toward violence, as well as mixed findings for race and several other factors. These findings synthesize theories on intergroup conflict with contemporary findings on affective polarization.
