The claim that elite political incivility can rouse partisan, antideliberative attitudes has many adherents, but the empirical record demonstrating a relationship is surprisingly limited. Yet the extant research suggests that incivility can stimulate aversive feelings, of the sort that discrete and dimensional theories of emotion predict should induce a partisan, antideliberative mode of citizenship among those exposed. Leveraging two online experiments, I address the questions of whether elite incivility provokes anger, rather than enthusiasm and anxiety, and whether the affective reactions induced by incivility yield the changes in deliberative attitudes that theories of emotion predict. I find that elite incivility, when counterattitudinal, rouses anger, which in turn can provoke an active and combative form of partisan citizenship. Despite claims to the contrary, the link between proattitudinal incivility, anger, and antideliberative attitudes is less clear. The results provide insight into the dynamics of discourse in the digital age, when affective polarization is the norm and elites commonly employ uncivil rhetoric.
