This is an excellent question (and reading through those articles now, thank you). I know she thinks about this a lot because her patients bring her research which is obviously broken, but why should they trust her? In her specific case she has done thousands and thousands of an extremely specialized operation - one of very few people in the world to have done that many. She keeps an open mind of course, but she also sees a lot of harm done. Medical research is hard, lots of confounding factors, and almost all the time in her particular area researchers have a very small n, so they draw conclusions because of the small n (and because they are often just not good at research, they are doctors!). I'm sure the scientific method will come through in the long run, that's my opinion, but along the way it is doing a lot of harm too.
