 These data suggest that the normative calculus is significantly more complicated than the present reading of Jonas suggests. The question is not whether it is permissible to risk harming some individuals in order to make other individuals slightly better off. Instead, we have to decide how to trade off the possibility of clinicians exposing patients to greater risks of harm (albeit with a still favorable risk-benefit ratio) in the process of treating them versus clinical researchers exposing participants to risk of harm in the process of trying to identify improved methods to treat others. This is not to say that there is no normative difference between these two activities, only that that difference is not accurately described as the difference between harming individuals versus improving their lot beyond some already acceptable status quo. It is not even a difference between harming some individuals versus allowing other individuals to suffer harms. The argument that needs to be made is that harming individuals in the process of conducting clinical research potentially involves a significant moral wrong not present when clinicians harm patients in the process of treating them.
