Public response to the COVID-19 pandemic provides a unique opportunity to study how lay people's risk perception involves their emotive responses. We investigated how outrage factors as emotional responses to risk influence levels of risk perception in the context of the pandemic disease. Furthermore, how media use influences the perception of outrage factors is also examined. A nationwide online survey (n = 1,000) was conducted in South Korea. The survey results indicated that pandemic risk perception was connected to the generic intensity of perceived outrage factors as measured by averaging the perception of multiple outrage factors. Individual outrage factors such as personal stake, effect on children, dread, and controllability directly influenced risk perception regarding COVID-19. When the intensity of media use was considered, individuals with heavy media use perceived outrage factors more intensely than those who used media less frequently. Media use also moderated the outrage effect of catastrophic potential and moral nature on the perception of risk associated with the pandemic disease. For heavy media users, the outrage effect of moral nature was increased, while that of catastrophic potential decreased. The implications of the outrage effect on the pandemic disease risk perception are addressed. Finally, we discuss the meaning of heavy media users' varying levels of vulnerability to outrage effect by moral nature and catastrophic potential.
