“The way we have been interpreting that is that people are experiencing a heightened level of disgust when they are socially evaluating or viewing interracial couples relative to same-race couples.” Researchers said there is a link between disgust and dehumanization, and therefore they sought in the third experiment to determine whether disgust “leads to dehumanization of interracial couples.” They studied 226 students, some of whom were shown 10 disgusting images, such as a dirty toilet or people vomiting.
