My concern is that GPs just imbibe this psycho-B***S*** uncritically and don't think to go to the biomedical literature to see for themselves.
I suspect that many - perhaps most - GPs will not understand scientific papers. They certainly don't seem to have the skills to critically analyse them, so won't be able to recognise what is quality research and what is BS.
This came as rather a shock to me after I gained my own medical science MSc, having thought that this would now enable me to discuss medical science on an equal footing with doctors. What I found was that I was now talking way over their heads, and was greeted with blank looks.
I have tried giving them printed sheets of summaries of relevant research, sometimes my own easy-to-read analyses and collations, but have never gained the impression that they have read them. There has never been any discussion about it. One doctor even refused to look at what I gave her.
Combining this with some (many?) doctors' obvious inability to understand the relevance of test results, I have been left feeling as though my health is in the hands of people who understand my illnesses less well than I do, and it is incredibly frustrating.
They do have some knowledge that I don't, and I had hoped that we could collaborate, using our different skills and knowledge to manage my health, but have just come up against brick walls most of the time.
