In 1925, Samuel Soal claimed to have taken part in a series of séances with the medium Blanche Cooper who contacted the spirit of a soldier Gordon Davis and revealed the house that he had lived in. Researchers later discovered fraud as the séances had taken place in 1922, not 1925. The magician and paranormal investigator Bob Couttie revealed that Davis was alive, Soal lived close to him and had altered the records of the sittings after checking out the house. Soal's co-workers knew that he had fiddled the results but were kept quiet with threats of libel suits.[145]

After her death in the 1980s the medium Doris Stokes was accused of fraud, by author and investigator Ian Wilson. Wilson stated that Mrs Stokes planted specific people in her audience and did prior research into her sitters.[177] Rita Goold a physical medium during the 1980s was accused of fraud, by the psychical researcher Tony Cornell. He claimed she would dress up as the spirits in her séances and would play music during them which provided cover for her to change clothes.[178]
Knowing which questions to ask a psychic takes a little thought because the questions you think you want to ask will deliver little to no results. For example, passive questions like, "Will I ever get married?" "When will I meet my next boyfriend?" are impossible to answer because the future is not bound and determined. Instead, ask questions that can aid a current situation that could affect your life down the road - like marriage. A good example would be something like, "My partner and I seem to be hitting a wall. What are the most effective tactics for improving my relationship?" You also want to avoid questions that are begging for reassurance (Should I get divorced?) or that are full of doubt. Remember that standing up for yourself will get you farther than looking for a hand to hold. Instead, ask results-driven questions like, "Why am I no longer as connected with my partner now than when I was first married." The more precise you are with your questions, the better reading you will receive, so put a pen to paper before jumping on the phone.
"Trance mediumship" is often seen as a form of mental mediumship. Most trance mediums remain conscious during a communication period, wherein a spirit uses the medium's mind to communicate. The spirit or spirits using the medium's mind influences the mind with the thoughts being conveyed. The medium allows the ego to step aside for the message to be delivered. At the same time, one has awareness of the thoughts coming through and may even influence the message with one's own bias. Such a trance is not to be confused with sleepwalking, as the patterns are entirely different. Castillo (1995) states,
In 1954, the psychical researcher Rudolf Lambert published a report revealing details about a case of fraud that was covered up by many early members of the Institute Metapsychique International (IMI).[166] Lambert who had studied Gustav Geley's files on the medium Eva Carrière discovered photographs depicting fraudulent ectoplasm taken by her companion Juliette Bisson.[166] Various "materializations" were artificially attached to Eva's hair by wires. The discovery was never published by Geley. Eugéne Osty (the director of the institute) and members Jean Meyer, Albert von Schrenck-Notzing and Charles Richet all knew about the fraudulent photographs but were firm believers in mediumship phenomena so demanded the scandal be kept secret.[166]

In the 1920s the British medium Charles Albert Beare duped the Spiritualist organization the Temple of Light into believing he had genuine mediumship powers. In 1931 Beare published a confession in the newspaper Daily Express. In the confession he stated "I have deceived hundreds of people…. I have been guilty of fraud and deception in spiritualistic practices by pretending that I was controlled by a spirit guide…. I am frankly and whole-heartedly sorry that I have allowed myself to deceive people."[124] Due to the exposure of William Hope and other fraudulent spiritualists, Arthur Conan Doyle in the 1920s led a mass resignation of eighty-four members of the Society for Psychical Research, as they believed the Society was opposed to spiritualism.[125]
