"It's quite incorrect to suggest that people with "zero intellectual curiosity" are sought out by medical schools, in fact it's a preposterous claim."

Medical schools are famous for only admitting people who A) went to college B) had high GPAs C) are 'well rounded', meaning they participated in lots of school clubs or whatever. This seems like more or less a recipe for selecting candidates with low intellectual curiosity. And as for empirical evidence, I believe it's also the book How Doctors Think book that quotes the statistic that the vast majority of doctors couldn't name a single finding published in their field's leading journal within the last year.
