Abstract
AbstractPolitical incivility—that is, treating political opponents with disrespect—and its consequences are increasingly investigated. This article examines the effect of incivility on message persuasiveness and the moderating role of populist attitudes and personality traits. We test these relationships via original experimental data collected in Switzerland (Study 1, N = 1340) and the United States (Study 2, N = 1820, preregistered). In both studies, participants were asked their opinion about a controversial political issue, presented with persuasive information framed either civilly or uncivilly, and asked again their opinion about the issue to assess whether they changed their mind. Results of a between‐subject design show that incivility does not necessarily undermine the message's persuasiveness, contrary to what we expected. Notably, uncivil messages resonated more with those respondents exhibiting higher levels of populist attitudes (Study 2) and darker personality traits (both studies). Our results further suggest a connection between incivility, message congruence, and particularly cultural context, which warrants further investigations.
