From its earliest beginnings to contemporary times, mediumship practices have had many instances of fraud and trickery.[55] Séances take place in darkness so the poor lighting conditions can become an easy opportunity for fraud. Physical mediumship that has been investigated by scientists has been discovered to be the result of deception and trickery.[56] Ectoplasm, a supposed paranormal substance, was revealed to have been made from cheesecloth, butter, muslin, and cloth. Mediums would also stick cut-out faces from magazines and newspapers onto cloth or on other props and use plastic dolls in their séances to pretend to their audiences spirits were contacting them.[57] Lewis Spence in his book An Encyclopaedia of Occultism (1960) wrote:

In the typical deep trance, the medium may not have clear recall of all the messages conveyed while in an altered state; such people generally work with an assistant. That person selectively wrote down or otherwise recorded the medium's words. Rarely did the assistant record the responding words of the sitter and other attendants. An example of this kind of relationship can be found in the early 20th century collaboration between the trance medium Mrs. Cecil M. Cook of the William T. Stead Memorial Center in Chicago (a religious body incorporated under the statutes of the State of Illinois) and the journalist Lloyd Kenyon Jones. The latter was a non-medium Spiritualist who transcribed Cook's messages in shorthand. He edited them for publication in book and pamphlet form.[25]


In a series of experiments in London at the house of William Crookes in February 1875, the medium Anna Eva Fay managed to fool Crookes into believing she had genuine psychic powers. Fay later confessed to her fraud and revealed the tricks she had used.[74] Frank Herne a British medium who formed a partnership with the medium Charles Williams was repeatedly exposed in fraudulent materialization séances.[75] In 1875, he was caught pretending to be a spirit during a séance in Liverpool and was found "clothed in about two yards of stiffened muslin, wound round his head and hanging down as far as his thigh."[76] Florence Cook had been "trained in the arts of the séance" by Herne and was repeatedly exposed as a fraudulent medium.[77]
An experiment conducted by the British Psychological Society in 2005 suggests that under the controlled condition of the experiment, people who claimed to be professional mediums do not demonstrate the mediumistic ability. In the experiment, mediums were assigned to work the participants chosen to be "sitters." The mediums claimed to contact the deceased who were related to the sitters. The research gather the numbers of the statements made and have the sitters rate the accuracy of the statements. The readings that were considered to be somewhat accurate by the sitters were very generalized, and the ones that were considered inaccurate were the ones that were very specific.[196]
Rebecca Rosen has served as a bridge between this world and those who have crossed over to the other side for the past 10 years. Her work has led to many guest appearances, including Entertainment Tonight, The Rachael Ray Show and Nightline, and her first book, Spirited: Connect to the Guides All Around You (HarperCollins). Due to the high and growing demand for spiritual truth, she has committed herself fulltime to serving as a medium and also educates thousands of people around the country with her seminars, lectures and workshops.

No doubt a great importance in the paranormal field is the problem of fraud. The field of psychic research and spiritualism has been so notoriously full of charlatans, such as the Fox sisters and Eusapia Palladino–individuals who claim to have special power and gifts but who are actually conjurers who have hoodwinked scientists and the public as well–that we have to be especially cautious about claims made on their behalf.[61] https://drive.google.com/file/d/1jfIdkes6t1TCleih9mebaywuoSViJSRK/view?usp=sharing

In 1936, the psychical researcher Nandor Fodor tested the Hungarian apport medium Lajos Pap in London and during the séance a dead snake appeared. Pap was searched and was found to be wearing a device under his robe, where he had hidden the snake.[160] A photograph taken at a séance in 1937 in London shows the medium Colin Evans "levitating" in mid air. He claimed that spirits had lifted him. Evans was later discovered to be a fraud as a cord leading from a device in his hand has indicated that it was himself who triggered the flash-photograph and that all he had done was jump from his chair into the air and pretend he had levitated.[161]


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".[173] 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.[174]
The medium Henry Slade was caught in fraud many times throughout his career. In a séance in 1876 in London Ray Lankester and Bryan Donkin snatched his slate before the "spirit" message was supposed to be written, and found the writing already there.[78] Slade also played an accordion with one hand under the table and claimed spirits would play it. The magician Chung Ling Soo revealed how Slade had performed the trick.[79]
