There's a website that has exposed what this guy does... it's an old scam like 20 questions, but with the help of videotape and assistants priming his pump.

I haven't seen the website for this guy specifically, but I remember seeing a two hour series hosted by some guy (I want to say Amazing Randy, but I'm not sure) who spends his time disproving frauds like this. Some of the tricks they use are pretty interesting, when he shows how they do it. That and with these sort of people, they're very good at 1) leading gullible people with questions, 2) and very good at reading the most subtle reactions with people. Much how the professional poker players read a person's tell sign.
