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.

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 ( = 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.
