I'm asking this as a skeptic who doesn't believe in palm reading, ESP or the mystical. Many orthodox Jews (I know several of them) visit Chassidic rebbes and mekubalim for palm reading and/or fortune-telling. The one I'm thinking of has a very brief conversation with you inquiring about your wellbeing, there is no cold reading or probing for information. He then looks at your palm and tells you something about yourself. I went to him once and wasn't particularly impressed, but it's how I know what happens in the room. Many people I know claim to have been completely shocked that he knew something about them he can't possibly have known.
Any ideas how this Rebbe (and others like him) accomplishes this? One theory is that he does research on you before you come in, aka, hot reading. I doubt that is the case for a few reasons, the primary one being that nobody would be shocked that he knew something that anyone can find out with a little research. Supposedly what he tells people can be known only by the person and maybe those close to him/her.
