Is ChatGPT going to output a bunch of unproven, small studies from Pubmed? I feel like patients are already doing this when they show up at the office with a stack of research papers. The doctor would trust something like Cochrane colab but a good doctor is already going to be working from that same set of knowledge.

In the case that the doctor isn't familiar with something accepted by science and the medical profession my experience is that they send you to another doctor that works with that particular drug or therapy. I've had this experience even with drugs that are generally accepted as safe.
