In 1917, Edward Clodd analyzed the mediumship of the trance medium Gladys Osborne Leonard and came to the conclusion that Leonard had known her séance sitters before she had held the séances, and could have easily obtained such information by natural means. The British psychiatrist Charles Arthur Mercier wrote in his book Spiritualism and Sir Oliver Lodge (1917) that Oliver Lodge had been duped into believing mediumship by trickery and his spiritualist views were based on assumptions and not scientific evidence. https://drive.google.com/file/d/1VGas_FxCztF6JXaSs-Rn8SoKa6GR5BOe/view?usp=sharing
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.
Magicians have a long history of exposing the fraudulent methods of mediumship. Early debunkers included Chung Ling Soo, Henry Evans and Julien Proskauer. Later magicians to reveal fraud were Joseph Dunninger, Harry Houdini and Joseph Rinn. Rose Mackenberg, a private investigator who worked with Houdini during the 1920s, was among the most prominent debunkers of psychic fraud during the mid-20th century.
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.

Browning seized the supposed materialized head, and it turned out to be the bare foot of Home. The deception was not helped by the fact that Browning never had lost a son in infancy."

Furthermore, she learned her trade from the mediums Frank Herne and Charles Williams, who were notorious for their cheating." Also see M. Lamar Keene. (1997). The Psychic Mafia. Prometheus Books. p. 64. ISBN 978-1-57392-161-9 "The most famous of materialization mediums, Florence Cook – though she managed to convince a scientist, Sir William Crookes, that she was genuine – was repeatedly exposed in fraud. Florence had been trained in the arts of the séance by Frank Herne, a well-known physical medium whose materializations were grabbed on more than one occasion and found to be the medium himself."
The British medium Francis Ward Monck was investigated by psychical researchers and discovered to be a fraud. On November 3, 1876 during the séance a sitter demanded that Monck be searched. Monck ran from the room, locked himself in another room and escaped out of a window. A pair of stuffed gloves was found in his room, as well as cheesecloth, reaching rods and other fraudulent devices in his luggage. After a trial Monck was convicted for his fraudulent mediumship and was sentenced to three months in prison. https://drive.google.com/file/d/1daHqn0IeY5p0VYJH2JxmL05muXLeMGc8/view?usp=sharing
The Danish medium Einer Nielsen was investigated by a committee from the Kristiania University in Norway, 1922 and discovered in a séance that his ectoplasm was fake. In 1923 the Polish medium Jan Guzyk was exposed as a fraud in a series of séances in Sorbonne in Paris. Guzyk would use his elbows and legs to move objects around the room and touch the sitters. According to Max Dessoir the trick of Guzyk was to use his "foot for psychic touches and sounds".
If everything is currently going well and you have a healthy relationship, your psychic reading can provide the reassurance you are looking for that your instincts are right – everything is fine. On the other hand, the reading may also alert you to a lurking issue that you will soon have to overcome in order for the intimate relationship to survive.
