The Folk Concept of Race
This chapter examines whether and how concepts vary across and within individuals (inter- and intra-individual variation) by examining what constrains variation of concepts. To address this issue, the chapter focuses on an independently interesting case study: inter- and intra-individual variation in the concept of race. The case study contrasts two competing hypotheses about the concept of race: the biological and the social hypotheses. According to the first hypothesis, the concept of race is a biological concept that is constrained by folk biology; according to the second, it is the concept of a social category. The chapter shows that people’s folk biology constrains the concept of race and thus limits how much concepts of race can vary within and across individuals.
