Ah ha ha! I have two very good friends who are peds...one is a specialist and the other is a general ped. Both of them would run circles around just about all of us, brainpower-wise. Don't kid yourself...doctors know a lot more about evaluating scientific literature than you think.
Speak for yourself....I have two very good friends at one of the top children's hospitals, one is a ped anaesthesiologist, the other is a NICU doctor. We were all about par in college and I can keep up with them brainpower-wise. But yes, they can generally run circles around all of the PCPs that I know. As for doctors...there's a huge range in scientific ability. Some are very good at evaluating the literature, and others not so much. More than would care to admit it just read article titles to "keep up with the literature".
