One of the best sources of information on how to run the psychic medium con is, unfortunately, the books written by psychic debunkers.
And the response to those books from the shadier sides of the industry, more often than not, is "The debunkers have to use those kinds of tricks, but I'm the real deal." In other words, they double down on the the prospect that the rubes won't figure out how it works. I guess we're supposed to believe that some magicians really do saw the lady in half despite the various common ways of creating the illusion.
I probably should revise my previous comments to say there are three camps. As I said, I know people who are basically just peer counselors who believe they have some sort of supernatural ability. These are generally the sort of people who say, "The spirit of your mother wants you to know she's proud of you and wants you to be happy." Okay, whatever. I tend to consider them harmless.
Then there are the stage mentalists who are primarily entertainers and want their audiences to know that going in. I guess those aren't the people we're talking about, but therre they are. The actor who played young Hodor in Game of Thrones is doing that sort of thing on the London stage these days.
The ones we have to watch out for are the ones who might have the potential to cause some real harm. "The spirit of your mother wants you to give me all your money." Or then also those commercial mediums who work strong and become very famous and rich, and you have to dig deeply into the fine print to find where they disavow any reliance you might want to take from them. I highly doubt these people believe they have a real gift any more than the stage mentalists who just don't happen to be as rich or famous.
