Polarization or Mainstreaming? How COVID-19 News Exposure Affects Perceived Seriousness of the Pandemic and the Susceptibility to COVID-19 Misinformation?

Two surveys investigated whether the exposure to COVID-19 news widens (polarization) or narrows (mainstreaming) the partisan gap in perceived seriousness of the pandemic, and how the perception affects individuals' susceptibility to COVID-19 misinformation that either exaggerates or downplays its health risks. Overall exposure to COVID-19 news homogenized the partisans' otherwise divergent risk perceptions, but the partisan divide was wider among those selectively approaching like-minded news outlets. Perceived seriousness of COVID-19 subsequently altered participants' susceptibility to either fear-arousing or fear-suppressing COVID-19 misinformation in a belief-confirming manner. It is discussed how news media shape the public's reality perception amid the global crisis.
