Most doctors are fucking dumb. Most don't even practice medice by exercising discretion. Most doctors follow best practices guides issued by the medical groups to which they belong in order to avoid malpractice, maintain insurance coverage, and get paid maximum $$$ by Medicare and the patients insurer.

So they literally practice check the box, incremental medicine, and they won't go out of order, meaning that most people are not properly diagnosed until a disease has significantly progressed, and only if they don't die first.

Many end up in the emergency room prior to diagnosis because their primary ignored their complaints, made them trasverse the best practices guide, and at significant cost, and during that time continually scheduled appointments weeks, if not months apart, thereby delaying actually effective care.

Modern medicine is a fucking joke and any doctor who supports that system is ipso facto guilty of malpractice.
