Stars-They're Sick Like Us! The Effects of a Celebrity Exemplar on COVID-19-Related Risk Cognitions, Emotions, and Preventative Behavioral Intentions

摘要

Research on exemplification suggests that celebrity health exemplars can exert a greater influence on public risk perceptions than exemplars featuring noncelebrities. In the aftermath of actor Tom Hanks's announcement that he tested positive for COVID-19, an online experiment compared the effects of his exemplar to an identical noncelebrity exemplar. Hanks's disclosure increased perceptions of susceptibility to the virus. The celebrity exemplar also increased anxiety, which increased intentions to engage in preventive behavior. These findings suggest that the mere presence of celebrity might function as a cognitive and affective heuristic that guides risk-related assessment and decision making.
