Psychic "mediums" are con artists. Most critically thinking individuals are readily aware of this fact, but a large portion of the general public seems unaware of this. Why else would Sylvia Brown be a frequent guest of Montel Williams (despite her being wrong, wrong, wrong on so many occasions)? Why else would John Edwards have had a popular day-time TV show?
In an attempt to inform the general public and help keep people from being swindled by these snake-oil salespeople, the BBC put three mediums up to the test. The result: they're all cheaters. Big surprise there. Video below:
They took three mediums to "The Chocolate Factory", a made up factory with a fictitious history which they published on an "official" website, as well as planting tidbits of info around the building (like a portrait of the fake original owner, complete with his name on a plaque). They then took the mediums through the building and asked them to "channel" the history of the factory.
They all were able to "divine" the fictional history of the factory. Funny how they could contact the ghost of a person who never even existed.
The reasonable explanation, of course, is that they had read the information of the website before hand. Nevertheless, they all presented the information as having come from a channeled spirit.
And, as usual, once they are told that the whole thing was made up, they attempted to make excuses: "Oh, I was just testing you", "oh, I was reading your thoughts instead", "oh I wasn't wearing my glasses when I standing in front of George Bull's portrait".
