Non-therapeutic research on children raises ethical concerns. Such research is not only conducted on individuals who are incapable of providing informed consent. It also typically involves some degree of risk or discomfort, without prospects of medically benefiting the participating children. Therefore, these children seem to be instrumentalized. Some ethicists, however, have tried to sidestep this problem by arguing that the children may indirectly benefit from participating in such research, in ways not related to the medical intervention as such. It has been argued, for example, that non-therapeutic pediatric research does not instrumentalize the children enrolled since it has the prospects of furthering their moral development. We argue that this argument is far too undeveloped to be taken seriously.
