A flatmate a few years ago was watching UK Living (a crappy UK satellite/cable channel) with a guy who is supposedly psychic on it. I laughed, and my flatmate took me up on a serious argument on why I didn't believe that guy could do what he claimed.
In the end it comes down to, what if it really worked, that it wasn't just all cheap parlour tricks. Imagine how many people would be employed in the police force using these skills for starters... or as private detectives, or pretty much any field of work that requires a level of investigation. Me knowing what went wrong with a computer in five minutes because I'm psychic and had a vision of the user deleting all his files... :-)
