Abstract:
We investigate the relationship between (a) official information on COVID-19 infection and death case counts; (b) beliefs about such case counts, at present and in the future; (c) beliefs about average infection chance—in principle, directly calculable from (b); and (d) self-reported health-protective behavior. We elicit (b), (c), and (d) with a daily online survey in the US from March to August 2020 (N =~ 13,900). Beliefs about future infection cases are closely related to official information, but are inconsistent with beliefs about infection chances—risk perceptions—which are better predictors of reported behavior. We discuss potential implications for public communication of health-risk information.
