It seems to me like the whole medical profession is a big celebration of having an ego problem. Some doctors carry themselves with so much hubris it's hard to imagine some of them making ANY rational decisions at all, and all their processes, right down to how medical records are kept, seem geared around expecting obedience from the patient without revealing enough details for scrutiny to be applied. Compare that against professions like engineering where a few notorious failures have led to the presence of cognitive biases in decision making being at least acknowledged to a degree.
