"If there's a steady paycheck in it, I'll believe anything you say." (Apologies if it's already been used. I'm not wading into a 7 year old thread right now.)
Really? Even the ones that have been done/proven in a lab (teleportation has been done, albeit it only involves particles). Faith healing "works" in that if a person really believes it can have results (psychosomatic results/symptoms works both ways).
Placebo effect. Works with medications, why shouldn't it work with a strong religious belief? RE: Levitation, not sure if this is what was meant in the poll, but there was a thing we old hippies used to play in the '70s (not necessarily involving controlled substances) where a group of six people could raise a seventh person to ceiling height on their fingertips. There was a kind of autohypnotic chant that everyone but the subject had to recite. It works. Participated in it as both levitator and levitatee dozens of times (it's very relaxing). But it's hypnosis, not anything supernatural. Wish I could remember the words of the chant. Might still make for an interesting party game...
That was it! Found it here (great minds and all that): http://www.playgroundjungle.com/2009/12/light-as-feather-stiff-as-board.html It does work. I've seen four average-size people (I misremembered it was six) lift a guy who weighed 250 pounds. And I didn't realize it had been around for so long...
