In such situations, the clairvoyant medium clearly understands that it is the powerful spirit and not he who is trotting out the facts so fast. It is in fact the spirit, which is providing him with facts, names of the persons and events, dates and other related information. The job of the clairvoyant medium then boils down to just working in tandem with this spiritual energy.
The psychologist and psychical researcher Stanley LeFevre Krebs had exposed the Bangs Sisters as frauds. During a séance he employed a hidden mirror and caught them tampering with a letter in an envelope and writing a reply in it under the table which they would pretend a spirit had written. The British materialization medium Rosina Mary Showers was caught in many fraudulent séances throughout her career. In 1874 during a séance with Edward William Cox a sitter looked into the cabinet and seized the spirit, the headdress fell off and was revealed to be Showers. https://drive.google.com/file/d/1-C6jcl_QIyLZgm95mFwRvd5fTPVkc8dG/view?usp=sharing
In 1970 two psychical researchers investigated the direct-voice medium Leslie Flint and found that all the "spirit" voices in his séance sounded exactly like himself and attributed his mediumship to "second-rate ventriloquism". The medium Arthur Ford died leaving specific instructions that all of his files should be burned. In 1971 after his death, psychical researchers discovered his files but instead of burning them they were examined and discovered to be filled with obituaries, newspaper articles and other information, which enabled Ford to research his séance sitters backgrounds.
Most working mediums are not fully developed most are clairsentient they can only sense and see spirit within the third eye all these working mediums want to be clairvoyant so again only go with your gut feeling when joining a circle, no one needs to tell you are a medium you know within yourself, your guides will help you to a development circle where the medium is humble and helpful teacher.
Senses used by mental mediums are sometimes defined differently from in other paranormal fields. A medium is said to have psychic abilities but not all psychics function as mediums. The term clairvoyance, for instance, may include seeing spirit and visions instilled by the spirit world. The Parapsychological Association defines "clairvoyance" as information derived directly from an external physical source.
