Pathogens, privilege, and purity: How pathogen threat and childhood socioeconomic status influence consumers’ condemnation of purity violations

Violations of moral purity, the moral foundation oriented toward protecting the sanctity of the body and soul, are not limited to social settings: brands, employees, and politicians are guilty of some pretty gross behaviors. Yet, we know surprisingly little about how consumers react to purity violations. In the current work, we propose that condemnation of purity violations is shaped by the combination of pathogen threat and childhood socioeconomic status (SES). We test this prediction across seven studies, collected pre- and mid-pandemic, using experimental manipulations of pathogen threat and measured differences in the perceived threat of COVID-19. We find that when pathogen threat is salient, people who grew up wealthy show a greater increase in condemnation of purity violations than people who grew up poor. Further, our results suggest this effect is due to class-based differences in the perceived controllability of pathogen threats.
