Yes, it is a puzzle.
Some medicos use homoeopathic treatments, for example. To get through medical school you can't really be dumb through and through. I think perhaps they're the sort of who enjoy being entertained by a "magic" show but have absolutely no interest in knowing how it was done. It's the experience that matters to them, not the dissection. In a sense they prefer to believe it really is magic that made the elephant disappear.
I
am in medical school, and they stuck in a couple of lectures on alternative medicine as part of our first and second years.
I think it backfired badly, because there was no real attempt to go into anything in enough depth to really understand it, and also because the lecturer was reather archly dismissive of some subjects while startlingly (to me) accepting of others. This led to an unbelievable amount of carping on the part of my classmates, but to my surprise most of it was "I can't believe he spent twenty minutes talking about CureX--that's such crap. And then he acted like CureY doesn't even work!" What CureX and CureY were in any given conversation varied widely and didn't have much to do with what the lecturer actually said, IMHO. It was basically ideas that they'd entered school with and already 'knew' were true, and that was that.
There was even a kind of
ad hoc committee forming to demand a full hour for some "real" alternative medicine practitioners to come in and speak to us (I recall aruveyda and homeopathy being touted), but fortunately that petered out before my skull exploded. (If they had, I planned to make myself very unpopular by asking some very difficult questions.)
Getting into med school requires a certain amount of scientific knowledge. it does not require that you actually learn to think scientifically. There's a difference.
The curriculum spends an inordinate amount of time on what is called 'evidence-based medicine', and to their credit they try very hard to explain the whole concept of how to read and assess a paper, but there is just not a lot of what I would call 'critical thinking' being taught. Which is probably inevitable, given the demands of med school, but I think the attempt to educate on this particular subject is doomed without it.
Sorry, that was longer than I meant it to be.
