Funny. I suspect that the difference in IQ between orthopaedic surgeons and anesthesiologists in the U.S. would be significantly greater given the difference in the mean Step I and II scores, and medical school grades. Don't know about grip strength.
I always find it interesting that orthopaedic surgeons play up to the stereotype of the dumb jock. Everyone knows that you guys are very smart, disciplined students. Why not embrace your intellectual prowess, as well as your physical strength? Is it so repugnant to the ortho community to be thought of as smart jocks, than dumb jocks?
