Who Supports Political Violence?

Abstract

The last few years have witnessed an increase in democratic backsliding in the United States - a decline in the quality of democracy, typically accompanied by an influx of non-normative behavior, such as political violence. Despite the real consequences of support for violence, fairly little is known about such an extremist attitude outside studies of terrorism or aggression. Using a unique survey containing many psychological, political, and social characteristics, we find that perceived victimhood, authoritarianism, populism, and white identity are the most powerful predictors of support for violence, though military service, conspiratorial thinking, anxiety, and feelings of powerlessness are also related. These patterns suggest that subjective feelings about being unjustly victimized - irrespective of the truth of the matter - and the psychological baggage that accompanies such feelings lie at the heart of support for violence. We use these results to build a profile of characteristics that explain support for violence; the predictive validity of this profile is then tested by examining its relationship with support for the January 6, 2021, U.S. Capitol riot, with which it is strongly associated, even accounting for support for Donald Trump. Our findings have implications for the detection of extremist attitudes and our understanding of the non-partisan/ideological foundations of anti-social political behavior.
