Changes in perceptions of media bias

Abstract

In this paper, we utilize a module from the Cooperative Congressional Election Study to explore how individual perceptions of media bias changed over the course of the 2016 presidential campaign. While previous literature has documented the role of partisan affiliation in perceptions of bias, we know considerably less about how these perceptions change during a presidential election. Consistent with existing theories of attitude change, perceptions of bias polarize with strong Democrats moving toward believing the media were biased against Hillary Clinton (and in favor of Donald Trump) and independent-leaning Republicans moving toward believing the media were biased against Donald Trump. At the end of the 2016 election, more individuals believed the media were biased against their side. These effects were moderated by how much attention individuals paid to the campaign.
