It's not like there can't be an accurate way to measure this. Pre-register patient problems, and see how fast doctors solve problems on average/median. Then it doesn't matter how jovial/amicable the doc is. With enough data you can fish out potential signals (and then test them properly), maybe bedside manner really doesn't matter, maybe being on time is more important. (Because then people spend less time in the cli…
Sorry no, it doesn't work like that. In either case. Doctors, like professors, are evaluated by former patients based on a mix of factors. In your doctor example, doctors don't "solve problems". They see patients. Many times these patients present with conflicting and hard-to-resolve symptoms. I imagine with the internet this has gotten worse. They use a mix of Occam's Razor, deductive reasoning, and social psycholog…
The vast majority of healtcare problems are dependent on using the right known technique (medication, surgery, etc.) and of course the problem is finding that, so diagnosis. Handing out morphine is not a solution in the genral case.
Long-term health is sadly largely independent of acute healthcare providers' work. It depends on genetics, environmental factors, behavior (exercise, diet, lifestyle) and a stochastic factor of acute problem solving (as the body breaks down more and more depends on doctors, and the fast and correct identification and application of the best healthcare technique).
So healthcare has two categories, the first is the common flu, I have some gastro issues, refer to specialist, manage chronic illnesses (diabetes, pain, low/high blood pressure) and the other is usually the problem for specialists, when they have no or wrong idea what's going on and thus an acute problem becomes a year(s) long trail of tears.
Now, that said, I'm not advocating for ignoring the edge cases and just use this one simple magic formula to decide who can play doctor. But we are still stuck in the dark, because we focus on the complexity, the long term, the human component, the expertise, yet fail to do the most basic thing to get at least somewhat reliable data.
And I'm aware of the problem of fishing for signals in data, but without it we can't even start the trial and error process, we can't differentiate between the two cases, and on average let's say we end up doing nothing.
Furthermore, we know that the obvious solution is to refactor the system. But that rarely presents a real possibility for education and human long term health. (You know, the small stuff :)) It'd be easy to ban smoking and alcohol and give less damaging stuff for people instead and spend more to treat addicts, and introduce negative income tax as a form of basic income to help poverty to reduce stress and help mental health to reduce number of smokers. Similarly it'd be easy to reform schools, and do all of the above to help parents to have more time for their kids so they get a better nurturing youth overall, which makes them ambitious and motivated to learn, study, explore and understand. And it'd be easy to do all this, but that's not likely. Hence the proposal for simple but maybe vastly effective changes.
