Where Motivated Reasoning Withers and Looms Large: Fear and Partisan Reactions to the COVID-19 Pandemic

Contemporary American politics has been largely characterized by hyperpartisanship and polarization, with partisan-motivated reasoning a thematic concern. Theories of emotions in politics suggest that anxiety might interrupt partisan heuristics and encourage citizens to reason more evenhandedly—but in what domains and to what extent? We use original panel data to assess how anxiety about becoming seriously ill from COVID-19 interacted with partisan attachments to shape political judgment during the COVID-19 pandemic. The structure of our data allows us to assess large-scale implications of politically relevant emotions in ways that so far have not been possible. We find large effects on policy attitudes: Republicans who were afraid of getting sick rejected signals from copartisan leaders by supporting mask mandates and the like. Effects on vote choice for Republicans were muted in comparison, but fear's large effect on independents may have been pivotal.
