When you say professional, my mind goes to the salary that is the most important thing about professionalism. I then associate ranking or goodness with money.>potential negatives and discount the potential benefits
Most are risk adverse, and going back to professionalism probably the more a bio-ethicist regulates, the more important they are and the more they might get paid (provided they don't go so far as to collapse the field). Their reward for benefits is probably not very direct. But these are just guesses, I know no professional bio-ethicists who have chosen to identity to me, anyway.>refusing to let prisoners participate
I did not know that. Many seem to want some prisoners to be forced into tests, but others will think about the Nazi government's use of prisoners and try to get distance from the policy.
Is the problem that prisoners are subjugated in some way that makes them incapable of consent? Something like how children and mentally ill can not necessarily consent?
