'More than skin-deep': biological essentialism in response to a distinctiveness threat in a stigmatized fan community.

We investigated how group distinctiveness threats affect essentialist beliefs about group membership in a stigmatized fan community. An experiment conducted on 817 members of the fan community revealed that highly identified fans who perceived significant stigmatization were the most likely to endorse essentialist beliefs about group membership when exposed to a distinctiveness threat via comparison to a highly similar (vs. dissimilar) outgroup.
