I think I might have a helpful analogy: the doctors you typically will see are like high school teachers. Going to a research hospital or, eg Mayo Clinic is like going to the professors. Even the professors are a mixed bag, but in my experience, asking a high school teacher for information within their subject area that's not specifically on the curriculum usually doesn't lead to satisfying results. Doctors on the ground are not to be put on a pedestal by any means. They're just people with biases, finite experience and education, providing advice based on mainstream ideas that were parroted to them by their teachers and mentors, just like any other profession.
