In sport and social justice, is genetic enhancement a game changer?

The possibility of genetic enhancement to increase the likelihood of success in sport and life's prospects raises questions for accounts of sport and theories of justice. These questions obviously include the fairness of such enhancement and its relationship to the goals of sport and demands of justice. Of equal interest, however, is the effect on our understanding of individual effort, merit, and desert of either discovering genetic contributions to components of such effort or recognizing the influence of social factors on the development and exercise of individual effort. This paper analyzes arguments about genetic enhancement with the goal of raising questions about how sport and justice regard unchosen, undeserved inequalities and what is assumed to be their opposite-namely, the exercise and results of individual effort. It is suggested that contemplating enhancement of natural assets previously outside human control may reinforce recognition of responsibility to intervene with regard to social advantages so as to support individual effort and improve individuals' life prospects.
