This chapter sets out to understand why racial (and quasi-racial ethnic) categories continue to be used in contemporary genetic research despite sustained criticism from natural and social scientists. It draws on interviews with geneticists working on the editorial boards of 19 high impact genetics journals which routinely publish research using racial or ethnic categories. These interviews suggest that geneticists are generally aware of the questionable reliability, validity, and sensitivity of these categories as markers of genetic variation. However, most geneticists seem to assume that the (modest) genetic differences observed among different populations make racial and ethnic categories useful (if not important) in their research. They also assume that the legitimate use of such categories in genetic research can (and should) be separated from their use as popular components of social identity or as determinants of discriminatory practice within society at large. This chapter argues that this is an essentially untenable position, because geneticists rely on the social salience of race and ethnicity to operationalize these categories as useful markers of geocultural ancestry, while their sociocultural correlates help geneticists understand the differential distribution and penetrance of genetic traits. Indeed, geneticists have effectively subsumed the ‘social constructionist’ critique of race and ethnicity by using the social nature of these concepts to improve their utility as tools for genetic research. This might explain why geneticists, and others, continue to use racial and ethnic categories

as if

these were reliable, valid and sensitive markers of substantial genetic variation despite evidence to the contrary.
