I can't tell you how many doctors I've had tell me, explicitly, within 15 minutes of having met me that they know my body, symptoms, and experience better than I do. It used to come much later in the process, after I'd spent months following their instructions to the letter and having my symptoms only get worse because they had completely overlooked or ignored some important piece of information I'd given them, so now I just ask in the very first appointment before I consider hiring that doctor to help me.
I think I understand why they do it. I have to imagine the overwhelming majority of people they see have only a grade school-level understanding of science, and a social media-level understanding of research. And doctors are used to being assumed to be the smartest person in the room (by themselves and everybody else, fairly or not).
But the complete failure to consider the possibility that I might also be intelligent, educated, and able to understand the applicable research just because my day job isn't in medicine immediately disqualifies a doctor for me.
I remember well my classmates who became doctors. A few of them were brilliant. Most of them were very good at repeating back information and not terribly good at forming their own insights. That's fine in many contexts. I just don't assume someone in a white coat is smarter than I am, much less knows me "better than I know myself," just because they got their advanced degree in a different field than I did.
