This essay considers principles of distributive justice for access to reproductive biotechnologies which make it is possible to enhance the traits of human offspring. I provide prima facie reason to think that redistributive principles apply to genetic goods and proceed to evaluate the way in which four distributive patterns - egalitarianism, luck egalitarianism, prioritarianism, and sufficientarianism - would implement a just distribution of genetic goods. I argue that the currency of genetic redistribution consists in natural primary goods like health, vision, (...) and rationality as these goods contribute to the biological component of basic capabilities, like being healthy, seeing properly, and being able to reason. I develop a mixed sufficiency/priority approach to genetic enhancement, and defend this approach against objections. (shrink)

In a little noted passage in A Theory of Justice, John Rawls argued that genetic intervention in the traits of offspring may be morally required as a matter of distributive justice. Given that the “greater natural assets” of each “enables him to pursue a preferred plan of life[,]” Rawls wrote, the parties to the original position “want to insure for their descendents the best genetic endowment.…Thus over time a society is to take steps at least to preserve the general level (...) of natural abilities and to prevent the diffusion of serious defects.…The pursuit of reasonable policies in this regard is something that earlier generations owe to later ones.” Whether biological enhancement actually is a moral obligation we owe to future generations is a question that I have taken up elsewhere, but which lies beyond my scope here. If we agree with Rawls that some measure of safe and effective genetic intervention may be required as a matter of justice, it stands to ask how the distribution of genetic goods – that is, the hereditary basis of human traits – should be carried out.

Opponents of genetic enhancement technologies often argue that the pursuit of these technologies will lead to self-defeating collective outcomes, massive social inequalities, or other forms of collective harm. They assume that these harms will outweigh individual benefits. Defenders of genetic enhancement technologies counter that individual benefits will outweigh collective harms and there will be no conflict between individual and collective interests. The present contribution tries to advance the debate by providing a more detailed discussion of the conditions under which individual (...) and collective interests may conflict.It presents a simple model that clarifies the conditions in which the use of genetic enhancement technologies may lead to self-defeating collective outcomes and social inequalities. It argues that given current inequalities, these conditions might indeed obtain as new genetic knowledge leads to a transition in population health. If they do, then genetic enhancement will steepen the social gradient in health. Thus, regulating access to enhancement technologies should be a matter of social justice. (shrink)
