Researchers recently have begun to examine how hostile media perceptions may promote discursive activities aimed at correcting the media's perceived negative influence. We use nationally representative survey data to test a moderated-mediation model that finds that hostile media perceptions significantly affect support for climate mitigation policies through the mediator of discussion and that the link between discussion and policy support is moderated in a three-way interaction with social network heterogeneity and political ideology. Discussion in homogeneous social networks increases opinion polarization between liberals and conservatives by intensifying conservatives' opinions, whereas discussion in heterogeneous social networks decreases polarization by moderating liberals' opinions.
