An amusing article by Mark Crislip for the Science Based Medicine blog. He could easily be writing about Chuck and Lency Spezzano and the whole Psychology of Vision scam.
Crislip's concluding sentence is right on and does partly explain why Chuck Spezzano dropped his gig being a "psychic" in his 1980 tour and changed to being a "healer":
"Don’t be a psychic, fortune teller or palm reader. Call yourself an alternative medical provider, you do not even need the quack miranda, and you will can get away with anything, no matter how ludicrous. Including exorcism."
