Depolarized by the Media? The Role of Heterogeneous and Homogeneous Traditional and Digital Media Diets in Issue Polarization Around COVID-19 in the United States

Abstract

Research suggests that a heterogeneous media diet can foster more objective information evaluations, reducing issue polarization as a result.These findings beg the question: Can increased news heterogeneity reduce issue polarization around COVID-19?Using data from a cross-sectional survey in the United States (N = 1,262), this study found that -in line with theoretical expectations -at high levels of homogeneity of traditional and digital news consumption, the difference in support for COVID-19 prevention between Biden and Trump supporters was significantly large.Conversely, this attitude gap narrowed at high news heterogeneity levels.Our results continue to advance research on the role of homogeneous and heterogeneous media diets and biased cognitive processing in issue polarization, a crucial endeavor as polarization poses a challenge to effective public health policy implementation and pandemic management.At the outset, the implications of our findings for pandemic communication (and health communication more generally) are discussed.
