Randomised, placebo-controlled, double-blind trials

Claims are often put forward by proponents of alternative remedies and therapies stating that they have tested their treatment and it has passed the test: proof that it works. Skeptics, however, insist that unless a treatment has passed a double-blind, placebo-controlled study, it is not valid.

The answer to those questions, of course, is that there’s no evidence to suggest that any of them are true; yet such claims persist, and although completely discredited, show no signs of abating.
