In 1930 the Polish medium Stanisława P. was tested at the Institut Metapsychique in Paris. French psychical researcher Eugéne Osty suspected in the séance that Stanislawa had freed her hand from control. Secret flashlight photographs that were taken revealed that her hand was free and she had moved objects on the séance table. It was claimed by spiritualists that during a series of séances in 1930 the medium Eileen J. Garrett channeled secret information from the spirit of the Lieutenant Herbert Carmichael Irwin who had died in the R101 crash a few days before the séance. Researcher Melvin Harris who studied the case wrote that the information described in Garrett's séances were "either commonplace, easily absorbed bits and pieces, or plain gobblede-gook. The so-called secret information just doesn't exist."
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. Frank Herne a British medium who formed a partnership with the medium Charles Williams was repeatedly exposed in fraudulent materialization séances. 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." Florence Cook had been "trained in the arts of the séance" by Herne and was repeatedly exposed as a fraudulent medium.
The same week that the Thomas John sting revelation was made in The New York Times, John's claimed mediumship abilities portrayed in the Lifetime reality TV show called Seatbelt Psychic were challenged by Gerbic in an article published by Skeptical Inquirer. In the show, John is a ride-share driver who surprises “unsuspecting” passengers when he delivers messages from their deceased relatives. Gerbic investigated and revealed that John's passengers are actually actors, several of which are documented in IMDb. Gerbic concluded that the riders were likely hired to ride with John, but were probably not acting when talking with him. She concluded that the details about their lives mentioned by John were easily found on social media sources, and likely fed to John, making the readings actually hot readings. One rider, Wendy Westmoreland, played a character on Stalked by a Doctor, a TV show also produced by Lifetime.
In the 1930s Harry Price (director of the National Laboratory of Psychical Research) had investigated the medium Helen Duncan and had her perform a number of test séances. She was suspected of swallowing cheesecloth which was then regurgitated as "ectoplasm". Price had proven through analysis of a sample of ectoplasm produced by Duncan, that it was made of cheesecloth. Helen Duncan would also use a doll made of a painted papier-mâché mask draped in an old sheet which she pretended to her sitters was a spirit. The photographs taken by Thomas Glendenning Hamilton in the 1930s of ectoplasm reveal the substance to be made of tissue paper and magazine cut-outs of people. The famous photograph taken by Hamilton of the medium Mary Ann Marshall depicts tissue paper with a cut out of Arthur Conan Doyle's head from a newspaper. Skeptics have suspected that Hamilton may have been behind the hoax.
It's important to know that the free psychic chat rooms are not for receiving free readings. The free chat rooms are for you to get to know the psychics before you invite them for a private reading. But that being said, it is totally possible to get a free answer or free reading during a free chat. There are many psychics who offer totally free psychic answers on a regular basis.
In the later half of the 20th century, Western mediumship developed in two different ways. One type involved clairaudience or sensitives who hear spirit, and then relay what they hear to their clients. The other incarnation of non-physical mediumship is a form of channeling in which the channeler goes into a trance, or "leaves their body", allowing a spirit entity to borrow their body, who then speaks through them. When in a trance the medium appears to come under the control of the spirit of a departed soul, sometimes entering into a cataleptic state, although modern channelers may not. Some channelers open the eyes when channeling, and remain able to walk and behave normally. The rhythm and the intonation of the voice may also change completely.
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. 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.
