Reminds me of I saw a documentary that followed students through med school. One of them was a former mechanic (not to mention a child prodigy and a biker- interesting guy) but he disliked the approach of med school where he would give a wrong diagnosis and his instructors would always tip toe around everyone's feelings and preface criticism with things like 'It's really interesting how you came to that conclusion..." but when he was a mechanic, someone would just say "You're doing it wrong - do it this way." And that's all he wanted - to be told if he was doing something wrong and how to do it right, but there was always this buffer of bullshit politeness in med school.
