Ambivalent attitudes promote support for extreme political actions

Abstract

Political extremism varies across people and contexts, but which beliefs will a person support through extreme actions? We propose that ambivalent attitudes, despite reducing normative political actions like voting, increase support for extreme political actions. We demonstrate this hypothesized reversal using dozens of measures across six studies ( N = 13,055). The effect was robust to relevant covariates and numerous methodological variations and was magnified when people’s attitudinal or ideological positions were more polarized. It appears to occur because being conflicted about political issues can feel psychologically uncomfortable, making extreme actions more appealing. Notably, this emerged when people thought ambivalence was justified, whereas leading them to consider ambivalence unjustified suppressed the effect, suggesting that ambivalent people are coping with but not necessarily trying to reduce their ambivalence. These results highlight the interplay of affective and cognitive influences in extreme behavior, showing that beliefs people feel justifiably conflicted about can promote extremism.
