Race, it is widely understood, is a social category that has no genetic basis, yet biological notions of race keep reemerging. Attempts to redress disparities in biomedical research emphasize recruiting racially representative trial participants. Forensic use of DNA evidence purports to pinpoint the race of a potential suspect. Genetic ancestry tracing companies explain test results to customers using racial categories. The makers of genomic databases seek to ensure racial inclusivity.
Jonathan Kahn argues that this predicament arises from a surprising source: the concept of diversity. Ranging across law, politics, science, and medicine, he examines the blurring of the distinction between social understandings of race and biological understandings of genetic variation. Because diversity has become such a central concept across domains, Kahn contends, it enables slippage between these contradictory ideas, entangling biological and social views of race. Tracing the parallel histories of the Human Genome Project, workforce diversification efforts, U. S. Supreme Court cases over affirmative action, the rise of precision medicine, and the COVID-19 vaccine trials, among others, he shows why diversity is often deployed in ways that threaten to biologize race or undermine efforts to address racial injustice. Combining incisive critique and interdisciplinary insight, The Uses of Diversity offers bracing new perspective on one of today's most vexed concepts.
