Ben Carson is an apparent moron, who thinks the pyramids were for grain storage. He'd fail a history course. He's also apparently a phenomenal brain surgeon.

Clinical skills and raw academic scores can be wildly disparate in a single person. Frankly, if I were picking a surgeon, I'd look for the one who enjoys tinkering with electronics and engines in their spare time.
