I’ve worked with a lot of surgeons and have heard/seen a lot of unbelievable things. Human beings are human. And often poorly educated in principles and ethics.
There's a reason physicians don't consider themselves scientists. If they make an error they can claim they knew from Tradition/Art/Authority.
It's politically impossible to outspend the US Physician Cartel (AMA), so I doubt we will have a Science based alternative or science based reform.
