Although these kinds of bioethical issues have already been raised in the context of genetic sequence data, the presumptively fixed and immutable nature of gene sequences shields the disclosure of genetic data from some of the thornier implications of epigenetics.
There are obviously no solid answers to these questions yet, given the state of both the science and contemporary public policy, but my project is to begin to ask these questions now in the case that the science of epigenetics begins to make its way into the public policy domain.
I’m not sure epigenetics constitutes such a fundamental shift in our understandings of genetics and inheritance as to actually warrant much change in our present policies [and] I don’t think society is about to start outlawing stuff because of its negative effects two generations down the road.
Given this history, recent work being done in areas like epigenetics suggests that our political theories need to be updated even more substantially to reflect these more recent modifications of our understanding of the connections between each other and our environments.
Does epigenetics challenge contemporary political ideologies? This small study may serve as a starting point for broader studies of epigenetics as it comes to affect political ideologies and, in turn, public policies. The narrative mix reported here could yet prove vulnerable to ideological capture, or, more optimistically, could portend the emergence of a "third-way" narrative using epigenetics to question atomistic individualism and allowing for less divisiveness in public-health domains such as obesity.
The gene-centric focus of molecular genetics is usually portrayed as the product of the inevitable and impartial progress of science, but the material effects of the Second World War and its aftermath on the particular trajectory of the science of genetics are rarely considered.
The politicization of biology in the West before and during the Cold War was to play a significant role in the development of the science of genetics in the West over the subsequent fifty years, particularly in the prejudice against epigenetics—which also helps to explain the recent and seemingly sudden (re)emergence of epigenetics within the last decade or so.
