I'm pretty sure most of us would call psychics are a subset of scammers. As a young man I use to do palm reading, not because I believed in it, but because it was a great way to get up close and personal with young women. Anyway, the lines all had rules and it was pretty easy to apply, just a basic algorithm of nonsense. About half of my future dates in the college days started out that way. Weird thing though, many people took it very seriously. A mother of a friend of mine mentioned to someone decades later that I was a palm reader. I told her that they are just folds in the skin but she refused to not believe. Magical thinking is really stubborn.
