How Strong Policy Attitudes Activate Support for Aggressive Political Action

There is a long history of political violence in the United States. Scholars have documented numerous dispositions that predict support for violence as a political tactic, finding that a general tendency toward aggression is consistently among the strongest predictors. Yet, we know much less about how political attitudes might activate aggressive personalities and direct them toward specific targets. In this paper, we examine how policy attitudes interact with dispositional aggression to motivate support for political violence. Across two studies, using novel measures and within-subjects designs, we show that intense policy opposition strongly predicts support for aggressive political tactics against politicians responsible for the legislation – primarily among those who are dispositionally prone to aggression. Surprisingly, the strength of partisan identity plays little role in explaining support for political aggression. Our findings suggest that policy attitudes are a crucial factor for understanding when aggressive individuals might turn to political violence.
