When you feel you are in a desperate situation, you will do desperate things and clutch at straws, even when you know those choices are irrational. I think this is the mindset behind the clutching at straws that quacks exploit with CAM, as in the Gonzalez Protocol for pancreatic cancer.
It is actually worse than doing nothing, worse than doing what main stream medicine recommends, but because there is the promise of complete recovery (even if it is a false promise), that is what people choose based on their irrational aversion to risk.
The framing of the end of life issue as a gain or a loss as in the monkey token exchange probably makes a gigantic difference in the choices made.
