This video shows a clip from a BBC show in which psychic mediums are tested. It’s an intriguing piece of television.
This far from the conclusive proof that’s needed to debunk psychic mediums. It doesn’t even mean the three featured are charlatans, let alone the whole industry.
As one of the psychics stated it could be that they were picking up vibes from the people who had made up the story. A made-up history of a place is just as out there in the ether as a real history.
What I would say however is that true psychic mediums shouldn’t be charging for their services. Which means the big stage shows conducted by household names are more theatrical in nature.
