Abstract
Through three studies (N = 306), we analysed the association between physical disgust and implicit biologization – the perception of others as disease organisms. In doing so, we employed an adapted version of the Semantic Misattribution Procedure (SMP). Study 1 found that the higher was the level of physical (vs. moral) disgust that White participants felt towards Black people, the higher was their implicit tendency to biologize this ethnic group. Study 2 and Study 3 experimentally replicated the association between physical disgust and biologization by manipulating physical disgust through vignettes that portrayed a target behaving in a physically (vs. morally vs. non-disgusting) way. Results showed that participants assigned to the physical disgust condition biologized more the target – both implicitly and explicitly – than participants in the moral disgust and non-disgusting condition.
Overall, these findings shed light on the biological dehumanization of others and its emotional roots, by thus paving the way for its prevention.
