Well, no offense but anecdotal evidence does not a large dataset make. I personally have the opposite experience. Since my parents are physicians I've grown up in and around hospitals all my life and met probably hundreds of physicians. In talking with them and talking with my parents about them I've found maybe two dozen that are either unscientific or incompetent. I completely agree that ~20% is way too high, but insulting all doctors based on your knowledge of maybe 3 or 4 of them is like saying all computer scientists are unscientific (although many are) just because you had a ten minute chat with three or four bottom-level PHP programmers.
Oh, I thought it was clear I was simply presenting this as counter-anecdotal evidence (although my anecdotal data set is probably an order of magnitude higher than the ops). I was arguing more for the null hypothesis than "physicians are definitely scientific."
