I'm sorry to cut in on this discussion, but I have a simple answer to the questions implicitly posed about doctors within the post and subsequent text that simply knocks all your arguments into a cocked hat. The answer to the conundrum of doctors' behaviour is quite simple.
There are three types of doctor. The first and most common type is the Dickhead. This is the type that thinks through the scrotal sac. Be the doctor male of female, because as is perfectly evident, the females of the species, once through the process of qualifying as a Dickhead, must inevitably become like the other Dickheads graduating from the Schools Of Medical Dickheads, and develop a quasi scrotal sack by virtue of proximity. A bit like a bitch without pups developing lactating mammaries when given an unweaned pup to nurse.
Along with the development of said sack and in direct but inverse proportion is the shrinkage of the part of the brain that governs humanity, from whence the original Hippocratic Oath sprang. Also from a person with a real scrotal sack, but he was probably gay anyway, so his scrotal tendencies were tempered with being in touch with the more intuitive side so often associated with females. (Wrongly, in my estimation. I have met too many human females without a shred of either conscience or compassion.) So thinking through the scrotal sack imbues the so-called thinker with an omniscient belief and Ptolemaic conceit that emerges thus: "I am God, I know all, I am right, you are wrong therefore you are either mad, lying or just plain inferior." Culminating eventually in any and all forms of behaviour from the Dickhead towards, and conversations with, patients who refuse to get well, in the medical equivalent of "F*** off."
The second type of doctor is the Nazi. Similar to the Dickhead but with the added bonus of being sadistic. This type buries their mistakes and malpractice and is rarely caught, unless the mode of death is too obvious and too frequent. Not to be confused with the psychopath, who deliberately kills off nuisance patients or those of whom certain aspects are found offensive.
The third type is an old breed and now, sadly, very rare. These are called TRMs, or The Real McCoys. These are men and women who retain a vocation for healing and alleviating suffering that is lodged in the same neural network in the brain as from whence the Hippocratic Oath sprang. These are men and women who can listen not only with their ears, but with that strange and elusive quality that is sometimes called intuition. They do not rely on computers or blood tests, seeing these intrusive forms of measurement as either an adjunct or a distraction.
TRMs retain a skill that the more modern Dickheads and Nazis have lost. That of diagnosis. Their ability to orchestrate their scientific understanding with this elusive quality of intuition, along with skill and experience and a dash of humility gives rise to the alternative moniker of Diagnostician.
But, like a rare and unusual example in any flock or herd, they are often mercilessly and persistently attacked by the rest of the flock or herd, and either pretend to be Dickheads and shrivel or die an untimely death. Alongside the creeping infection of the medical-test virus, this means that the Diagnostician is a very rare type indeed.
