Over at Respectful Insolence today's posting is "You want to know how to make a surgeon angry?" The short answer is
"Surgeons and other medical staff are the equivalent of technicians, engineers, plumbers or carpenters. They are not scientists. They are not studying the details of the relevant science. They don't have to understand it - just carry out procedures by rote. Though the ones who do have a clue will be a lot better at adapting to new circumstances because they'll make more correct guesses based on their understanding than the clueless ones will."
