The recent uptick in genetic testing for a range of illnesses has prompted great debate in the medical community about how reliable and useful the testing is, as well as discussion among social scientists about the social and ethical consequences of the testing. One line of inquiry that has been around a bit longer is about biological thinking, specifically as it is related to stigma and inequality. In particular, there is a fascinating and timely discussion of the geneticization of mental illness by Jo Phelan (2005) that, even before the emergence of the current debate about technology, delved into the promise and perils of genetic thinking – though not specifically about genetic testing. For instance, Phelan addresses issues of stigma and labeling associated with seeing mental illness as a genetic problem. Phelan finds that stigma is, at the same time, both enhanced and alleviated by geneticization. In other words, if an illness is genetic, it removes the feelings of responsibility from the sufferer and makes it more difficult for others to blame him or her for said illness. The illness and the person who embodies said condition, then, are not seen as one and the same. However, the same genetic thinking opens the door to a range of new judgments that can be detrimental both in terms of self-concept and the way in which others make assumptions about those who experience, in this case, mental illness. There has been some, but not much work, overall, in the social sciences, about the social problems associated with genetic testing (for a lovely summary, see the article linked below). In the last few weeks, genetic testing has been thrust into the forefront once again after fervent debate that ended with Eric Holder, US Attorney General ruling that genes cannot be patented – thus, genes are in the public domain – even though companies like “Myriad,” a testing company, already possess the patent to two human genes (and it is unclear what will happen to these patents).
Drawing on the existent literature on genetic testing, Richard Tutton (whose recent article in Sociology Compass is linked below) reviews the literature on genetic testing and calls for sociologists to pay more attention to these issues. Though Tutton does not address issues of inequality directly, the recent debate on access to genetic testing led me to wonder, for instance, who can afford the testing? Who will it be offered to? Will insurance cover it? How might this testing “blame” ethnic/racial groups for illness? In reference to the Phelan article mentioned above, would knowing one is predestined to developed depression, for instance, change the way we see someone struggling with that condition? And on and on and on. Tutton does survey the literature on the use of genetic testing and forensics and there is clearly an open door to an over-reliance on an imperfect technology when someone’s freedom or life hangs in the balance. One of the great fears about genetic testing is that it will become a central determining factor in whether we see people as “criminal” or not — a frightening idea.
