In a study in which doctors and patients were asked to say whether they had received the real drug or the placebo, 80 per cent of the patients and 87 per cent of the doctors were right, as opposed to the 50 per cent that would be expected by random guessing.
This seems a better "hit rate" than some of the cited evidence for the existence of psychic powers, which don't seem able to break the blind in double-blind trials!
