John Edward is a douche with a TV show. He claims that he can contact the dead, but what he's really practicing is
mentalism. It's not a paranormal or extrasensory ability, it's an array of techniques anyone can learn. In effect, anyone who has ever attempted to persuade or "charm" people into doing something or trusting them has practiced a little mentalism. And I bet a lot of you have.
Mind-reading, contacting the dead, etc, are all mentalism magic tricks. There's nothing paranormal about them. In fact, they're exceedingly normal; everyone uses tricks like these in everyday communication.
