alt Hacker NewsSo, the guy who does brain surgery on you... you want him to have taken some electives he was interested in, passed for having a pulse, then sent off to work in the operating room? Or, should he be required to have gotten at least 80% of questions right on a test of his surgical knowledge?
In the practice professions (Doc, Law, accounts, even "blue collar" ones ) - experience is much more indicative of skill than test scores.
So as a thumb, you want to ideally go to the brain surgeon who's done that surgery the most.
