We found exactly that: overall, participants showed a heightened level of activation in the insula when looking at interracial couples relative to looking at same-race couples.
Although the insula is not exclusively linked to disgust, taken with the results of our first study these findings suggest that people do tend to be more likely to experience disgust when viewing interracial couples.
So we wondered whether the disgust people experience in response to interracial couples might lead them to dehumanize them.
To test this, we recruited another predominately white sample of college students and divided them into two groups.
Yet even though attitudes have supposedly changed, contemporary commentary on interracial marriage will still refer to a “gag reflex” that some people continue to feel – as The Washington Post’s Richard Cohen noted a few years ago.
