I sometimes had to assist a surgeon that was a professor, no less, and he was a complete idiot, IMO. Knew a lot of stuff, but a defective human being.
I worked with a lot of surgeons that obviously had degrees, and while many were actual well functioning human beings, some were anything but. IMO a degree says nothing about a person with one, other than they know a lot of stuff and can write papers. It doesn't make them a good or even clever person.
