However, the religion and its beliefs continue in spite of this, with physical mediumship and seances falling out of practice and platform mediumship coming to the fore. In the late 1920s and early 1930s there were around one quarter of a million practising Spiritualists and some two thousand Spiritualist societies in the UK in addition to flourishing microcultures of platform mediumship and 'home circles'. Spiritualism continues to be practised, primarily through various denominational Spiritualist churches in the United States, Canada, Australia and the United Kingdom. In the United Kingdom, over 340 Spiritualist churches and centres open their doors to the public and free demonstrations of mediumship are regularly performed.

Demonstrations of mediumship

In old-line Spiritualism, a portion of the services, generally toward the end, is given over to demonstrations of mediumship through purported contact with the spirits of the dead. A typical example of this way of describing a mediumistic church service is found in the 1958 autobiography of C. Dorreen Phillips. She writes of the worship services at the Spiritualist Camp Chesterfield in Chesterfield, Indiana: "Services are held each afternoon, consisting of hymns, a lecture on philosophy, and demonstrations of mediumship." Today "demonstration of mediumship" is part of the church service at all churches affiliated with the

Mental mediumship

"Mental mediumship" is communication of spirits with a medium by

telepathy Telepathy () is the purported vicarious transmission of information from one person's mind to another's without using any known human sensory channels or physical interaction. The term was first coined in 1882 by the classical scholar Frederic ...

. The medium mentally "hears" (clairaudience), "sees" (clairvoyance), and/or feels (clairsentience) messages from spirits. Directly or with the help of a spirit guide, the medium passes the information on to the message's recipient(s). When a medium is doing a "reading" for a particular person, that person is known as the "sitter".

Trance mediumship

"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

as one of the most famous trance mediums in the history of Spiritualism. 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.

Physical mediumship is defined as manipulation of energies and energy systems by spirits. This type of mediumship is claimed to involve perceptible manifestations, such as loud raps and noises, voices, materialized objects, apports, materialized spirit bodies, or body parts such as hands, legs and feet. The medium is used as a source of power for such spirit manifestations. By some accounts, this was achieved by using the energy or ectoplasm released by a medium, see

Direct voice

Direct voice communication is the claim that spirits speak independently of the medium, who facilitates the phenomenon rather than produces it. The role of the medium is to make the connection between the physical and spirit worlds. Trumpets are often utilised to amplify the signal, and directed voice mediums are sometimes known as "trumpet mediums". This form of mediumship also permits the medium to participate in the discourse during séances, since the medium's voice is not required by the spirit to communicate.

has written:

Cold reading also explains why psychics have consistently failed scientific tests of their powers. By isolating them from their clients, psychics are unable to pick up information from the way those clients dress or behave. By presenting all of the volunteers involved in the test with all of the readings, they are prevented from attributing meaning to their own reading, and therefore can't identify it from readings made for others. As a result, the type of highly successful hit rate that psychics enjoy on a daily basis comes crashing down and the truth emerges – their success depends on a fascinating application of psychology and not the existence of paranormal abilities.

The results showed a greater percentage of believers reporting that the table had moved. In another experiment the believers had also reported that a handbell had moved when it had remained stationary and expressed their belief that the fake séances contained genuine paranormal phenomena.

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. In 1876, William Eglinton was exposed as a fraud when the Parapsychology, psychical researcher Thomas Colley seized a "spirit" materialization in his séance and cut off a portion of its cloak. It was discovered that the cut piece matched a cloth found in Eglinton's suitcase. Colley also pulled the beard off the materialization and it was revealed to be a fake, the same as another one found in the suitcase of Eglinton. In 1880 in a

During the séance a materialized spirit was seized and found to be Rita and a bottle of phosphorus oil, muslin and a false beard were found amongst the two mediums. In 1882 C. E. Wood was exposed in a séance in Peterborough. Her Indian spirit control "Pocka" was found to be the medium on her knees, covered in muslin. In 1880 the American stage mentalist Washington Irving Bishop published a book revealing how mediums would use secret codes as the trick for their Clairvoyance, clairvoyant readings.

In 1891 at a public séance with twenty sitters the medium Cecil Husk was caught leaning over a table pretending to be a spirit by covering his face with phosphor material. The magician Will Goldston also exposed the fraud mediumship of Husk. In a séance Goldston attended a pale face materialization appeared in the room. Goldston wrote "I saw at once that it was a gauze mask, and that the moustache attached to it was loose at one side through lack of gum. I pulled at the mask. It came away, revealing the face of Husk." The British materialization medium Annie Fairlamb Mellon was exposed as a fraud on October 12, 1894. During the séance a sitter seized the materialized spirit, and found it to be the Mellon on her knees with white muslin on her head and shoulders. The magician Samri Baldwin exposed the tricks of the Davenport brothers in his book ''The Secrets of Mahatma Land Explained'' (1895). The medium Swami Laura Horos was convicted of fraud several times and was tried for rape and fraud in London in 1901. She was described by the magician

as "one of the most extraordinary fake mediums and mystery swindlers the world has ever known". In the late 19th century, the fraudulent methods of Spirit photography, spirit photographers such as David Duguid (medium), David Duguid and Edward Wyllie were revealed by psychical researchers. Hereward Carrington documented various methods (with diagrams) how the medium would manipulate the Photographic plate, plates before, during, and after the séance to produce spirit forms. The ectoplasm materializations of the French medium Eva Carrière were exposed as fraudulent. The fake ectoplasm of Carrière was made of cut-out paper faces from newspapers and magazines on which fold marks could sometimes be seen from the photographs. Cut out faces that she used included Woodrow Wilson, King Ferdinand of Bulgaria, French president Raymond Poincaré and the actress Mona Delza. The séance trick of the Eddy Brothers was revealed by the magician

in 1898. The brothers utilized a fake hand made of lead, and with their hands free from control would play musical instruments and move objects in the séance room. The physiologist Ivor Lloyd Tuckett examined a case of

that William Thomas Stead, W. T. Stead had claimed was genuine. Stead visited a photographer who had produced a photograph of him with deceased soldier known as "Piet Botha". Stead claimed that the photographer could not have come across any information about Piet Botha, however, Tuckett discovered that an article in 1899 had been published on Pietrus Botha in a weekly magazine with a portrait and personal details. The trance medium

was investigated by psychical researchers and psychologists in the late 19th and early 20th century. In an experiment to test if Piper's "spirit" controls were purely fictitious the psychologist G. Stanley Hall invented a niece called Bessie Beals and asked Piper's 'control' to get in touch with it. Bessie appeared, answered questions and accepted Hall as her uncle. The psychologist Joseph Jastrow wrote that Piper pretended to be controlled by spirits and fell into simple and logical traps from her comments. Science writer Martin Gardner concluded Piper was a Cold reading, cold reader that would "fish" for information from her séance sitters. The physiologist Ivor Lloyd Tuckett who examined Piper's mediumship in detail wrote it could be explained by "muscle-reading, fishing, guessing, hints obtained in the sitting, knowledge surreptitiously obtained, knowledge acquired in the interval between sittings and lastly, facts already within Mrs. Piper's knowledge."

1900s

In March 1902 in Berlin, police officers interrupted a séance of the German apport medium Frau Anna Rothe. Her hands were grabbed and she was wrestled to the ground. A female police assistant physically examined Rothe and discovered 157 flowers as well as Orange (fruit), oranges and lemons hidden in her petticoat. She was arrested and charged with fraud. Another apport medium Hilda Lewis known as the "flower medium" confessed to fraud. The psychical researchers W. W. Baggally and Everard Feilding exposed the British materialization medium Christopher Chambers as a fraud in 1905. A false moustache was discovered in the séance room which he used to fabricate the spirit materializations. The British medium Charles Eldred was exposed as a fraud in 1906. Eldred would sit in a chair in a curtained off area in the room known as a "séance cabinet". Various spirit figures would emerge from the cabinet and move around the séance room, however, it was discovered that the chair had a secret compartment that contained beards, cloths, masks, and wigs that Eldred would dress up in to fake the spirits. The spirit photographer William Hope (paranormal investigator), William Hope tricked

In 1908 at a hotel in Naples, the psychical researchers W. W. Baggally, Hereward Carrington and Everard Feilding attended a series of séances with

. In a report they claimed that genuine supernatural activity had occurred in the séances, this report became known as the Feilding report. In 1910, Feilding returned to Naples, but this time accompanied with the magician William S. Marriott. Unlike the 1908 sittings, Feilding and Marriott detected her cheating, just as she had done in America. Her deceptions were obvious. Palladino evaded control and was caught moving objects with her foot, shaking the curtain with her hands, moving the cabinet table with her elbow and touching the séance sitters. Milbourne Christopher wrote regarding the exposure "when one knows how a feat can be done and what to look for, only the most skillful performer can maintain the illusion in the face of such informed scrutiny." Stanisława Tomczyk and William Marriott

In 1910 at a séance in Grenoble, France the apport medium Charles Bailey (medium), Charles Bailey produced two live birds in the séance room. Bailey was unaware that the dealer he had bought the birds from was present in the séance and he was exposed as a fraud. The psychical researcher Eric Dingwall observed the medium Bert Reese in New York and claimed to have discovered his billet reading tricks. The most detailed account at exposing his tricks (with diagrams) was by the magician Theodore Annemann. The Polish medium Stanisława Tomczyk's levitation of a glass beaker was exposed and replicated in 1910 by the magician William S. Marriott by means of a hidden thread. The Italian medium Lucia Sordi was exposed in 1911, she was bound to a chair by psychical researchers but would free herself during her séances. The tricks of another Italian medium Linda Gazzera were revealed in the same year, she would release her hands and feet from control in her séances and use them. Gazzera would not permit anyone to search her before a séance sitting, as she concealed muslin and other objects in her hair. 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. In 1918, Joseph Jastrow wrote about the tricks of

who was an expert at freeing her hands and feet from the control in the séance room. In the séance room Palladino would move curtains from a distance by releasing a jet of air from a rubber bulb that she had in her hand. According to the psychical researcher Harry Price "Her tricks were usually childish: long hairs attached to small objects in order to produce 'telekinetic movements'; the gradual substitution of one hand for two when being controlled by sitters; the production of 'phenomena' with a foot which had been surreptitiously removed from its shoe and so on." 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." Due to the exposure of William Hope (paranormal investigator), William Hope and other fraudulent spiritualists, Arthur Conan Doyle in the 1920s led a mass resignation of eighty-four members of the

, as they believed the Society was opposed to spiritualism. Between 8 November and 31 December 1920 Gustav Geley of the Institute Metapsychique International attended fourteen séances with the medium Franek Kluski in Paris. A bowl of hot paraffin was placed in the room and according to Kluski spirits dipped their limbs into the Paraffin wax, paraffin and then into a bath of water to materialize. Three other series of séances were held in Warsaw in Kluski's own apartment, these took place over a period of three years. Kluski was not searched in any of the séances. Photographs of the molds were obtained during the four series of experiments and were published by Geley in 1924.D. Scott Rogo. (1978). ''Mind and Motion: The Riddle of Psychokinesis''. Taplinger Publishing. pp. 245–46.

The British direct-voice medium Frederick Tansley Munnings was exposed as a fraud when one of his séance sitters turned the lights on which revealed him to be holding a trumpet by means of a telescopic extension piece and using an angle piece to change the auditory effect of his voice. Richard Hodgson (parapsychologist), Richard Hodgson held six sittings with the medium Rosina Thompson and came to the conclusion she was a fraud as he discovered Thompson had access to documents and information about her séance sitters. On 4 February 1922, Harry Price with James Seymour, Eric Dingwall and William S. Marriott had proven the spirit photographer William Hope (paranormal investigator), William Hope was a fraud during tests at the British College of Psychic Science. Price wrote in his SPR report "William Hope has been found guilty of deliberately substituting his own plates for those of a sitter... It implies that the medium brings to the sitting a duplicate slide and faked plates for fraudulent purposes."Photos of Ghosts: The Burden of Believing the Unbelievable by Massimo Polidoro
/ref> The medium Kathleen Goligher was investigated by the physicist Edmund Edward Fournier d'Albe. On July 22, 1921, in a séance he observed Goligher holding the table up with her foot. He also discovered that her ectoplasm was made of muslin. During a séance d'Albe observed white muslin between Goligher's feet. The Danish medium Einer Nielsen was investigated by a committee from the University of Oslo, 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". The psychical researchers Eric Dingwall and Harry Price re-published an anonymous work written by a former medium entitled ''Revelations of a Spirit Medium'' (1922) which exposed the tricks of mediumship and the fraudulent methods of producing "spirit hands". Originally all the copies of the book were bought up by spiritualists and deliberately destroyed. In 1923, the magician Carlos María de Heredia revealed how fake spirit hands could be made by using a rubber glove, paraffin and a jar of cold water. The Hungarian medium Ladislas Lasslo confessed that all of his spirit materializations were fraudulent in 1924. A séance sitter was also found to be working as a confederate for Lasslo.

The Austrian medium Rudi Schneider was investigated in 1924 by the physicists Stefan Meyer (physicist), Stefan Meyer and Karl Przibram. They caught Rudi freeing his arm in a series of séances. Rudi claimed he could Levitation (paranormal), levitate objects but according to Harry Price a photograph taken on April 28, 1932, showed that Rudi had managed to free his arm to move a handkerchief from the table. According to Warren Jay Vinton, Schneider was an expert at freeing himself from control in the séance room. Oliver Gatty and Theodore Besterman who tested Schneider concluded that in their tests there was "no good evidence that Rudi Schneider possesses supernormal powers." The spiritualists Arthur Conan Doyle and William Thomas Stead, W. T. Stead were duped into believing Julius and Agnes Zancig had genuine psychic powers. Both Doyle and Stead wrote that the Zancigs performed

. In 1924 Julius and Agnes Zancig confessed that their Mentalism, mind reading act was a trick and published the secret code and all the details of the trick method they had used under the title of ''Our Secrets!!'' in a London Newspaper. 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.

claimed to materialize a "spirit hand", but when examined by biologists the hand was discovered to be made from a piece of carved animal liver. The German apport medium Heinrich Melzer was discovered to be a fraud in 1926. In a séance psychical researchers found that Melzer had small stones attached to the back of his ears by flesh coloured tape. Psychical researchers who investigated the mediumship of Maria Silbert revealed that she used her feet and toes to move objects in the séance room. 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." Helen-duncan-platexi

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. Psychologists and researchers who studied Pearl Curran's

s in the 1930s came to the conclusion Patience Worth was a fictitious creation of Curran. In 1931 George Valiantine was exposed as a fraud in the séance room as it was discovered that he produced fraudulent "spirit" fingerprints in wax. The "spirit" thumbprint that Valiantine claimed belonged to Arthur Conan Doyle was revealed to be the print of his big toe on his right foot. It was also revealed that Valiantine made some of the prints with his elbow. The medium Frank Decker (medium), Frank Decker was exposed as a fraud in 1932. A magician and séance sitter who called himself M. Taylor presented a mail bag and Decker agreed to lock himself inside it. During the séance objects were moved around the room and it was claimed spirits had released Decker from the bag. It was later discovered to have been a trick as Martin Sunshine, a magic dealer admitted that he sold Decker a trick mail bag, such as stage Escapology, escapologists use, and had acted as the medium's confederate by pretending to be M. Taylor, a magician. The British medium Estelle Roberts claimed to materialize an Indian spirit guide called "Red Cloud". Researcher Melvin Harris who examined some photographs of Red Cloud wrote the face was the same as Roberts and she had dressed up in a feathered war-bonnet. In 1936, the psychical researcher Nandor Fodor tested the Hungarian apport medium Lajos Pap in

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. A photograph taken at a séance in 1937 in London shows the medium Colin Evans (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. According to the magician John Booth (magician), John Booth the stage mentalist David Devant managed to fool a number of people into believing he had genuine

ability who did not realize that his feats were magic tricks. At St. George's Hall, London he performed a fake "clairvoyant" act where he would read a message sealed inside an envelope. The spiritualist Oliver Lodge who was present in the audience was duped by the trick and claimed that Devant had used psychic powers. In 1936 Devant in his book ''Secrets of My Magic'' revealed the trick method he had used. The physicist Kristian Birkeland exposed the fraud of the direct voice medium Etta Wriedt. Birkeland turned on the lights during a séance, snatched her trumpets and discovered that the "spirit" noises were caused by chemical explosions induced by potassium and water and in other cases by lycopodium powder. The British medium Isa Northage claimed to materialize the spirit of a surgeon known as Dr. Reynolds. When photographs taken of Reynolds were analyzed by researchers they discovered that Northage looked like Reynolds with a glued stage beard. The magician Julien Proskauer revealed that the levitating trumpet of Jack Webber was a trick. Close examination of photographs reveal Webber to be holding a telescopic reaching rod attached to the trumpet, and sitters in his séances only believed it to have levitated because the room was so dark they could not see the rod. Webber would cover the rod with crepe paper to disguise its real construction. Kathleen Goligher fake ectoplasm

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).Sofie Lachapelle. (2011). ''Investigating the Supernatural: From Spiritism and Occultism to Psychical Research and Metapsychics in France, 1853–1931''. Johns Hopkins University Press. pp. 144–45. Lambert who had studied Gustav Geley's files on the medium Eva Carrière discovered photographs depicting fraudulent ectoplasm taken by her companion Juliette Bisson. 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. The fraudulent medium Ronald Edwin confessed he had duped his séance sitters and revealed the fraudulent methods he had used in his book ''Clock Without Hands'' (1955). The psychical researcher Tony Cornell investigated the mediumship of Alec Harris in 1955. During the séance "spirit" materializations emerged from a cabinet and walked around the room. Cornell wrote that a stomach rumble, nicotine smelling breath and a pulse gave it away that all the spirit figures were in fact Harris and that he had dressed up as each one behind the cabinet. The British medium William Roy (medium), William Roy earned over £50,000 from his séance sitters. He confessed to fraud in 1958 revealing the microphone and trick-apparatus that he had used. The

s of the Irish medium Geraldine Cummins were analyzed by psychical researchers in the 1960s and they revealed that she worked as a cataloguer at the National Library of Ireland and took information from various books that would appear in her automatic writings about ancient history. In 1960, psychic investigator Andrija Puharich and Tom O'Neill, publisher of the Spiritualist magazine ''Psychic Observer'', arranged to film two seances at Camp Chesterfield, Indiana, using infrared film, intending to procure scientific proof of spirit materializations. The medium was shown the camera beforehand, and was aware that she was being filmed. However, the film revealed obvious fraud on the part of the medium and her cabinet assistant. The exposé was published in the 10 July 1960 issue of the ''Psychic Observer''.Allen Spraggett, ''The Unexplained'', (New York: New American Library, 1967). In 1966 the son of James Pike, Bishop Pike committed suicide. After his death, Pike contacted the British medium Ena Twigg for a series of séances and she claimed to have communicated with his son. Although Twigg denied formerly knowing anything about Pike and his son, the magician John Booth discovered that Twigg had already known information about the Pike family before the séances. Twigg had belonged to the same denomination of Bishop Pike, he had preached at a cathedral in Kent and she had known information about him and his deceased son from newspapers. In 1970 two psychical researchers investigated the direct-voice medium

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 (psychic), 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. Ronald Pearsall in his book ''Table-rappers: The Victorians and the Occult'' (1972) documented how every Victorian medium investigated had been exposed as using trickery, in the book he revealed how mediums would even use acrobatic techniques during séances to convince audiences of spirit presences. In 1976, M. Lamar Keene, a medium in Florida and at the

Camp Chesterfield in

, confessed to defrauding the public in his book ''The Psychic Mafia''. M. Lamar Keene, Keene detailed a multitude of common stage magic techniques utilized by mediums which are supposed to give an appearance of paranormal powers or supernatural involvement. After her death in the 1980s the medium Doris Stokes was accused of fraud, by author and investigator Ian Wilson (author), Ian Wilson. Wilson stated that Mrs Stokes planted specific people in her audience and did prior research into her sitters. 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. Silver Belle Fraud

The British journalist

published the book ''The Spiritualists'' (1983) which exposed the fraud of the Victorian mediums. The book received positive reviews and has been influential to skeptics of spiritualism. The British apport medium Paul McElhoney was exposed as a fraud during a séance in Osset, Yorkshire in 1983. The tape recorder that McElhoney took to his séances was investigated and a black tape was discovered bound around the battery compartment and inside Dianthus caryophyllus, carnation flowers were found as well as a key-ring torch and other objects. In 1988, the magician Bob Couttie criticized the paranormal author Brian Inglis for deliberately ignoring evidence of fraud in mediumship. Couttie wrote Inglis had not familiarized himself with magician techniques. In 1990 the researcher Gordon Stein discovered that the Levitation (paranormal), levitation photograph of the medium Carmine Mirabelli was fraudulent. The photograph was a trick as there were signs of chemical retouching under Mirabelli's feet. The retouching showed that Mirabelli was not levitating but was standing on a ladder which was erased from the photograph. In 1991, Wendy M. Grossman, Wendy Grossman in the ''New Scientist'' criticized the parapsychologist Stephen E. Braude for ignoring evidence of fraud in mediumship. According to Grossman "[Braude] accuses sceptics of ignoring the evidence he believes is solid, but himself ignores evidence that does not suit him. If a medium was caught cheating on some occasions, he says, the rest of that medium's phenomena were still genuine." Grossman came to the conclusion that Braude did not do proper research on the subject and should study "the art of conjuring." In 1992,

analyzed the Feilding report of

and argued that she employed a secret accomplice that could enter the room by a fake door panel positioned near the séance cabinet. Wiseman discovered this trick was already mentioned in a book from 1851, he also visited a carpenter and skilled magician who constructed a door within an hour with a false panel. The accomplice was suspected to be her second husband, who insisted on bringing Palladino to the hotel where the séances took place. Massimo Polidoro and Gian Marco Rinaldi also analyzed the Feilding report but came to the conclusion no secret accomplice was needed as Palladino during the 1908 Naples séances could have produced the phenomena by using her foot. Colin Fry was exposed in 1992 when during a séance the lights were unexpectedly turned on and he was seen holding a spirit trumpet in the air, which the audience had been led to believe was being levitated by spiritual energy. In 1997, Massimo Polidoro and Luigi Garlaschelli produced wax-moulds directly from one's hand which were exactly the same copies as Gustav Geley obtained from Franek Kluski, which are kept at the Institute Metapsychique International. A series of mediumistic séances known as the Scole Experiment took place between 1993 and 1998 in the presence of the researchers David Fontana, Arthur Ellison and Montague Keen. This has produced photographs, audio recordings and physical objects which appeared in the dark séance room (known as apports). A criticism of the experiment was that it was flawed because it did not rule out the possibility of fraud. The skeptical investigator Brian Dunning (skeptic), Brian Dunning wrote the Scole experiments fail in many ways. The séances were held in the basement of two of the mediums, only total darkness was allowed with no night vision apparatus as it might "frighten the spirits away". The box containing the film was not examined and could easily have been accessible to fraud. And finally, even though many years have passed, there has been no follow-up, no further research by any credible agency or published accounts.

The VERITAS Research Program of the Laboratory for Advances in Consciousness and Health in the Department of Psychology at the University of Arizona, run by the parapsychologist Gary Schwartz, was created primarily to test the hypothesis that the consciousness (or identity) of a person survives physical death. Schwartz claimed his experiments were indicative of survival, but do not yet provide conclusive proof. The experiments described by Schwartz have received criticism from the scientific community for being inadequately designed and using poor controls. Ray Hyman discovered many methodological errors with Schwartz's research including; "Inappropriate control comparisons", "Failure to use double-blind procedures", "Creating non-falsifiable outcomes by reinterpreting failures as successes" and "Failure to independently check on facts the sitters endorsed as true". Hyman wrote "Even if the research program were not compromised by these defects, the claims being made would require replication by independent investigators." Hyman criticizes Schwartz's decision to publish his results without gathering "evidence for their hypothesis that would meet generally accepted scientific criteria... they have lost credibility." In 2003, skeptic investigator Massimo Polidoro in his book ''Secrets of the Psychics'' documented the history of fraud in mediumship and spiritualistic practices as well as the psychology of psychic deception. Terence Hines in his book ''Pseudoscience and the Paranormal'' (2003) has written:

Modern spiritualists and psychics keep detailed files on their victims. As might be expected, these files can be very valuable and are often passed on from one medium or psychic to another when one retires or dies. Even if a psychic doesn't use a private detective or have immediate access to driver's license records and such, there is still a very powerful technique that will allow the psychic to convince people that the psychic knows all about them, their problems, and their deep personal secrets, fears, and desires. The technique is called cold reading and is probably as old as charlatanism itself... If John Edward (or any of the other self-proclaimed speakers with the dead) really could communicate with the dead, it would be a trivial matter to prove it. All that would be necessary would be for him to contact any of the thousands of missing persons who are presumed dead—famous (e.g., Jimmy Hoffa, Judge Crater) or otherwise—and correctly report where the body is. Of course, this is never done. All we get, instead, are platitudes to the effect that Aunt Millie, who liked green plates, is happy on the other side.

An experiment conducted by the

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. On Fox News on the Geraldo at Large show, October 6, 2007, Geraldo Rivera and other investigators accused Schwartz of being a fraud as he had overstepped his position as a university researcher by requesting over three million dollars from a bereaved father who had lost his son. Gary Schwartz, Schwartz claimed to have contacted the spirit of a 25-year-old man in the bathroom of his parents house and it is alleged he attempted to charge the family 3.5 million dollars for his mediumship services. Schwartz responded saying that the allegations were set up to destroy his science credibility. In 2013 Rose Marks and family psychic fraud, Rose Marks and members of her family were convicted of fraud for a series of crimes spanning 20 years entailing between $20 and $45 million. They told vulnerable clients that to solve their problems they had to give the purported psychics money and valuables. Marks and family promised to return the cash and goods after "cleansing" them. Prosecutors established they had no intent to return the property.. The exposures of fraudulent activity led to a rapid decline in ectoplasm and materialization séances. Investigator Joe Nickell has written that modern self-proclaimed mediums like

, Rosemary Altea and James Van Praagh are avoiding the Victorian tradition of dark rooms, spirit handwriting and flying tambourines as these methods risk exposure. They instead use "mental mediumship" tactics like cold reading or gleaning information from sitters beforehand (hot reading). Group readings also improve hits by making general statements with conviction, which will fit at least one person in the audience. Shows are carefully edited before airing to show only what appears to be hits and removing anything that does not reflect well on the medium. Michael Shermer criticized mediums in ''

'', saying, "mediums are unethical and dangerous: they prey on the emotions of the grieving. As grief counselors know, death is best faced head-on as a part of life." Shermer wrote that the human urge to seek connections between events that may form patterns meaningful for survival is a function of natural evolution, and called the alleged ability of mediums to talk to the dead "a well-known illusion of a meaningful pattern." According to James Randi, a skeptic who has debunked many claims of psychic ability and uncovered fraudulent practices, mediums who do cold readings "fish, suggest possibilities, make educated guesses and give options." Randi has a standing offer of One Million Dollar Paranormal Challenge, $1 million US dollars for anyone who can demonstrate psychic ability under controlled conditions. Most prominent psychics and mediums have not taken up his offer. The key role in mediumship of this sort is played by "effect of subjective confirmation" (see Barnum effect) — people are predisposed to consider reliable that information which though is casual coincidence or a guess, however it seems to them personally important and significant and answers their personal belief. The article about this phenomenon in ''Encyclopædia Britannica'' places emphasis that "… one by one spiritual mediums were convicted of fraud, sometimes using the tricks borrowed from scenic "magicians" to convince their paranormal abilities". In the article it is also noted that "… the opening of the wide ranging fraud happening on spiritualistic sessions caused serious damage to reputation of the movement of a Spiritualism and in the USA pushed it on the public periphery".Spiritualism (religion). www.britannica.com. In March 2017, medium Thomas John Flanagan, Thomas John was targeted in a sting operation and caught doing a hot reading. The sting was planned and implemented by Skeptical movement, skeptical activist Susan Gerbic and mentalist Mark Edward. The unmarried couple attended John's show using Pseudonym, aliases, and were "read" as a married couple Susanna and Mark Wilson by John. During the entire reading, John failed to determine the actual identities of Gerbic and Edward, or that they were being deceptive during his reading. All personal information he gave them matched what was on their falsified Facebook accounts, rather than being about their actual lives, and John pretended he was getting this information from Gerbic and Edward's supposedly dead—but actually nonexistent—relatives. As Jack Hitt reported in The New York Times: These details were from the falsified Facebook accounts for the pair which were prepared by a group of Skeptical movement, skeptics in advance of the reading, and Gerbic and Edward were not aware of the specific information in these accounts. This blinding was done in order to avoid John later being able to claim he obtained the false information by reading Gerbic and Edward's minds. In her report, Gerbic also revealed that during an after-show private event, John disclosed in a group setting that at least one of the people in the audience which he did a reading about was actually his own student. 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 (TV network), Lifetime reality show, reality TV show called ''Seatbelt Psychic'' were challenged by Gerbic in an article published by Skeptical Inquirer. In the show, John is a ridesharing company, ride-share driver who surprises “unsuspecting” passengers when he delivers messages from their death, 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.
