Abstract
Humans possess disease avoidance mechanisms, which promote xenophobic attitudes under conditions of perceived vulnerability to disease (PVD). We investigate whether concerns about disease vulnerability influence attraction to olfactory cues of self-similarity. Participants donated a sample of their body odour, then completed a PVD questionnaire (subscales: germ aversion, perceived infectability; Duncan et al. 2009). Told that they were rating strangers’ odours, participants rated self, versus non-self, scent donations. Among women, attraction to self-scent was positively predicted by germ aversion (but not perceived infectability); surprisingly, men’s ratings of self-scent were negatively associated with germ aversion. Priming with pathogenic cues did not influence scent preferences. This association between germ aversion and odour preference suggests that mere scent exposure can inform the receiver of the immunological similarity between self and sender, which can influence social responses (i.e. attraction to vs. avoidance of scent sender). We discuss these results, as well as implications for the study of intergroup biases.
