 To take one possibility, it is not clear that this view can be defended by appeal to physicians’ role responsibilities. A prima facie plausible view holds that physicians’ role responsibilities apply to all encounters between physicians and patients who need medical treatment. This view would imply that physicians may not compromise patients’ medical interests when conducting therapeutic studies, but also seems to prohibit non-therapeutic research procedures with patients. Alternatively, one might argue that physicians’ role responsibilities apply only in the context of clinical care and so do not apply in the context of clinical research at all. This articulation yields a more plausible view, but does not support the use of the therapeutic/ non-therapeutic distinction. It provides no reason to think that physicians’ obligations differ based on the type of research in question.
