I'm not a believer in any of it. Too often desperate, hurting people are targeted and will read into it what they want. South Park shows just how successful cold reading is by Stan becoming an acclaimed medium when he's actually trying to show everyone how fake it is.
Penn Jilette is talking to Adam Savage here about how he taught his actress girlfriend to be a fake psychic, and how well it worked.
Shows like The Mentalist, Psych, Bull and Lie to Me are all good examples of how observation yields more than we think we may be giving out. Just like stage 'magic', I find it interesting to see behind the curtain at how these things work.
As with my thoughts on religion, if it gives people hope, comfort or happiness, I'm glad. That is, as long as it doesn't exploit them.
My husband's godmother has been suckered out of so much money by a charlatan who sold her magic water that's supposed to cure her cancer. She eventually upgraded to paying even more to buy a magic empowered credit-card sized thing. She has to put her water on top of it for a few minutes before drinking it so it can be infused with the healing powers.
