This is a super important point that I don't think a lot of people fully recognize. Medicine is a super interesting comparison because you honestly don't need to go all that far back to find some pretty egregious examples of doctors making things much worse due to ignorance or incompetence. My favorite example of this is the assassination of President Garfield, who most likely died not to the bullet wound itself but from the doctors rummaging around to try to find the bullet with unsanitized hands, causing infection and damaging organs...on the wrong side of his body[1].
