Do we need a device to acquire ethnic concepts?

Francisco Gil-White argues that the ubiquity of racialism-the view that so-called races have biological essences-can be explained as a by-product of a shared mental module dedicated to ethnic cognition. Gil-White's theory has been endorsed, with some revisions, by Edouard Machery and Luc Faucher. In this skeptical response I argue that our developmental environments contain a wealth, rather than a poverty of racialist stimulus, rendering a nativist explanation of racialism redundant. I also argue that we should not theorize racialism in isolation from racism, as value judgments may play a role in essentialist thinking about the 'other'.
