What sex is permissible, if any, in non-clinical research relationships? In reply to my call for a code of conduct for non-clinical research, some commentators have called for more training in such matters, but this kind of training will not go very far without some kind of governing standards yet to be determined. It is not enough to assume that unarticulated opinions will suffice. Neither will approaches that involve even greater scrutiny over research, as if to divide research into two (...) categories: one in which sex with subjects is permissible and the other in which sex is impermissible. No practical solution to exploitation will be more important than having a code of ethics that guides decision-makers where institutional review bodies do not tread. (shrink)
