The influence of contagious disease threat on general risk-taking tendency

Abstract

We conducted two studies to investigate the effects of the threat of a contagious disease on people s tendency to engage in risk-taking behaviors that are not directly related to the disease, such as investment decisions. In Study 1 we demonstrated that individual differences in germ\n aversion influenced risk-taking tendency. Participants with relatively high germ aversion were less likely than were those with relatively low germ aversion to engage in risk-taking behaviors encompassing the ethical, investment, gambling, recreational, health, and social domains. In Study\n 2 we replicated the results of Study 1 in a different setting and examined the underlying process by which perceived disease threat inhibits risk taking. The findings suggest that the threat of disease-induced negative affect decreased risk-taking tendencies. This implies that precautionary\n behavior activated by disease-threat salience can extend beyond the health domain to a broader range of situations.
