Why do some many people think it's 'fake'
He doesn't claim to have magic powers or anything.
All he does is use techniques used for years by people who claim they have powers. He uses suggestion, misdirection, and a good knowledge of human nature. These things work. What about subliminal messages in music and advertisement? What about lie detectors, or any other equipment using subliminal movement? What about politicians, and other people in the public eye using suggestion to convince people. He uses similar means.
Not everyone is easily swayed by suggestion, and misdirection. Through the magic of television producers can cut out most of the unsuccessful pieces. That's not to say it's all luck; I'm sure he knows what he's doing.
If you are a skeptic... Obviously at some point a person has suggested you know enough not be taken in by something. You've been convinced not to believe someone can manipulate your free will.
If you don't believe in sociology, then you don't believe anything I've just said, but that's just ignorant.
