"The capacity for self-deception, rarely acknowledged or understood by those who offer us supernatural answers to our problems, is huge: as easy as it is to make a medium’s cold-reading statements ‘fit’ our own situation and come to believe that he must have some paranormal insight, it is hardly any more difficult for a would-be psychic with an average ego, upon hearing frequently positive feedback, to believe over time that he must be blessed with a special gift. It’s harder to think you’re doing it for real when you’re tossing tambourines in the dark or have ready-made ectoplasm stuffed into your mouth or bottom."
