The emergence of genomic science in the last quarter century has revolutionized medicine, the justice system, and our understanding of who we are. We use genomics to determine guilt and exonerate the falsely convicted; devise new medicines; test embryos; and discover our ethnic and national roots. One might think that, given these advances, most would favor the availability of genomic tools. Yet as Jennifer Hochschild explains in Genomic Politics, the uses of genomic science are both politically charged and hotly contested. After all, genomics might result in bioterrorism, a demand for "designer babies," or a revival of racial biology. Political divisions around genomics do not follow the usual left-right ideological patterns that dominate most of American politics. Through four controversial innovations resulting from genomic science—medicines for heart disease approved for use by only African-Americans, on the grounds of genetic distinctiveness; use of DNA evidence in the criminal justice system; the search for one's roots through genetic ancestry; and the use of genetic tests in prenatal exams—Hochschild reveals how the phenomenon is polarizing America in novel ways. Advocates of genomic science argue that these applications will make life better, while opponents point out the potential for misuse—from racial profiling to "selecting out" fetuses that gene tests show to have conditions like Down syndrome. Hochschild's central message is that the divide hinges on answers to two questions: How significant are genetic factors in explaining human traits and behaviors? And what is the right balance between risk acceptance and risk avoidance for a society grappling with innovations arising from genomic science? Experts differ among themselves about who should make decisions about governing genomics' uses, and Americans as a whole trust almost no one to do so. A deeply researched and original analysis of the politics surrounding one of the signal issues of our times, this is essential reading for anyone interested in how the genetics revolution is shaping society.
