How Right-Leaning Media Coverage of COVID-19 Facilitated the Spread of Misinformation in the Early Stages of the Pandemic
In recent weeks, several academic and journalistic outlets have documented widespread misinformation about the origins and potential treatment for COVID-19. This misinformation could have important public health consequences if misinformed people are less likely to heed the advice of public health experts. While some have anecdotally tied the prevalence of misinformation to misleading or inaccurate media coverage of the pandemic in its early stages, few have rigorously tested this claim empirically. In this paper, we report the results of an automated content analysis showing that right-leaning news outlets (e.g., Fox News, Breitbart) were more than 2.5 times more likely than mainstream outlets to discuss COVID-19 misinformation during the early stages of the U.S. pandemic response. In a nationally representative survey (N = 8,914) conducted from 3/10-3/16, we then show that people who consumed more right-leaning news during this timeframe were more than twice as likely to endorse COVID-related misinformation. Alarmingly, survey data further suggest that misinformation endorsement has negative public health consequences, as misinformed people are more likely to believe that the CDC is exaggerating COVID-related health risks.
