text: You've asked a BRILLIANT question. Indeed, if psychics "know all", why aren't they able to control their own lives, avoid accidents, get rich on stocks or the lottery? \n\nThe answer is clearly, they DON'T know "all", in fact, they don't know anything except how to bilk money out of gullible people. Commercial psychics use tricks of observation to ferret out "tells" (like in poker) about someone and make general statements that could apply to anyone similar to the poor deluded client. Using their powers of observation and generalizations about people, they tell the client amazingly accurate things that they figured out (no spirit doing the channeling, sorry.)\n\n Here's a prediction; despite being debunked, psychics will continue to have customers, because as Barnum said "A sucker is born every minute."
