Hi Deirdre,
Having been diagnosed by 5 different doctors and a specialist over a period of 5 weeks based on the simple fact that no one bothered to read further back on my record than my last hospital test, I think we can add the power of proper listening or observation to the things medical practitioners should know. Humans make mistakes and when they build simulated environments like schools they rob themselves of the juicy details of reality in trade for the convenience of rightness, prediction and further simulated performance. On the belief there are people out there so well trained they can imagine reality into existence we follow their proofs and not the reality we are presented.
To me, “qualified to practice” is a comfort (or maybe an approximation of a comfort) but as an assurance that the system behind it functions properly is not good evidence. By saying that I know there are many things to learn and many people more qualified than myself to learn them from. Yet this doesn’t diminish my ability process the world as I see it. Though of course we don't ask the receiver--we test them.
