Misinformation and the Paradox of Trust during the covid-19 pandemic in the U.S.: pathways to Risk perception and compliance behaviors

As declared “infodemic” by the World Health Organization, the proliferation of Covid-19 misinformation has posed a significant challenge to public health efforts to tackle the pandemic. Despite initial evidence on the association between misinformation and behavior, researchers have yet to fully identify intervening variables to account for the behavioral effects of Covid-19 misinformation. To address this question, this study aims to examine whether and how consuming misinformation would predict public trust in health and political institutions, and in turn, shape risk perception and adherence to preventive behaviors. We conducted a web-based survey using a nationally representative sample of 1,400 U.S. adults in October 2020. We found that Covid-19 misinformation exposure was linked to lower trust in public health experts but higher trust in government, which led to a decrease in the perceived severity of Covid-19 and less compliance with public health guidance. Our findings uncover the complex social and psychological processes by which misinformation consumption undermines public health efforts during the pandemic crisis.
