Society for Psychical Research
|Legal status||Non-profit organisation|
|Prof John Poynton|
The Society for Psychical Research (SPR) is a non-profit organisation in the United Kingdom. Its stated purpose is to understand "events and abilities commonly described as psychic or paranormal by promoting and supporting important research in this area" and to "examine allegedly paranormal phenomena in a scientific and unbiased way." It does not however, since its inception in 1882, hold any corporate opinions: SPR members have a variety of beliefs or lack thereof about the reality and nature of the phenomena studied, and some sceptics have been active members of the Society.
The SPR was founded in 1882 in London by a group of eminent thinkers including Edmund Gurney, Frederic W. H. Myers, William F. Barrett, Henry Sidgwick, and Edmund Dawson Rogers. The SPR was the first organisation of its kind in the world, its stated purpose being "to approach these varied problems without prejudice or prepossession of any kind, and in the same spirit of exact and unimpassioned enquiry which has enabled science to solve so many problems, once not less obscure nor less hotly debated."
Initially six committees were established: on Thought-Transference, Mesmerism and similar phenomena, Mediumship, Reichenbach Phenomena (Odic Force), Apparitions and Haunted Houses, physical phenomena associated with séances, and the Literary Committee which studied the history of these phenomena. Critical SPR investigations into purported mediums and the exposure of fake mediums led to a number of resignations in the 1880s by Spiritualist members but the Society continued to investigate mediums, studying Gladys Osborne Leonard, Eusapia Palladino, Leonora Piper, Rudi Schneider among others.
Much of the early work involved investigating, exposing and in some cases duplicating fake phenomena. Richard Hodgson (parapsychologist) distinguished himself in that area. In 1884 Hodgson was sent by the SPR to India to investigate Helena Blavatsky and concluded that her claims of psychic power were fraudulent. Among the phenomena that Hodgson investigated was the supposed miraculous Theosophical letters from the Mahatmas which were said to magically appear over a four-year period in a cabinet in the Shrine Room at the Theosophical headquarters in Madres. Hodgson in his report wrote that the letters were frauds and had been written by Blavatsky herself who had put them in the cabinet from an opening in her bedroom located behind the Shrine room. In April 1986, Vernon Harrison examined the evidence of the case and outlined flaws in Hodgson's work. Harrison concluded that the letters were forgeries but were not written by Blavatsky but by ex-employees for revenge. On May 8 of that year the SPR issued a press release in support of Harrison's findings, and rejecting the Hodgson report.
In 1886 and 1887 in a series of publications the SPR exposed the tricks of many mediums. One of the most interesting exposures of that period was carried out by Hodgson with his friend, S. J. Davey. Originating the “fake séance” technique for educating the public (including SPR members), Davey gave sittings under an assumed name, duplicating the slate-writing phenomena produced by a medium named William Eglinton, and then proceeded to point out to the sitters the manner in which they had been deceived. Because of this, some spiritualist members such as William Stainton Moses resigned from the SPR. Due to the exposure of William Hope and other fraudulent spiritualists, Arthur Conan Doyle led a mass resignation of eighty-four members of the Society for Psychical Research, as they believed the Society was opposed to spiritualism.
According to D. Scott Rogo "For years a feud existed between the Spiritualists who saw the SPR as unnecessarily sceptical and the SPR which saw Spiritualists as credulous or simplistic." As the SPR progressed many of the members came to interpret mediumship and spiritualist phenomena in terms of psychokinesis and telepathy opposed to the spiritualist hypothesis. This explanation for spiritualistic phenomena prevailed in the SPR, and is still supported by parapsychological researchers to this day. On this subject Terence Hines wrote "The split came about not because of doubt on the part of the scientists who belonged to the SPR, but because of a fundamental difference with spiritualists over the correct interpretation of the phenomena that took place at séances." The parapsychological claim that mediumship can be explained by psychokinesis or telepathy is not accepted by the scientific community.
In 1966 the SPR member Simeon Edmunds published Spiritualism: A Critical Survey which concluded the majority of mediums that had been investigated were fraudulent. The SPR member Tony Cornell spent over 50 years investigating the paranormal and came to the conclusion that most paranormal cases turn out to have natural explanations such as the result of fraud, pranks and misidentification. He believed that many sightings of ghosts, hauntings and poltergeists are products of the human mind. Cornell estimated that of the 800 cases that he investigated, only twenty percent were difficult to explain and only a handful were paranormal. Some sceptical members have resigned from the SPR. Eric Dingwall resigned and wrote "After sixty years' experience and personal acquaintance with most of the leading parapsychologists of that period I do not think I could name half a dozen whom I could call objective students who honestly wished to discover the truth."
The SPR is frequently referred to in Victorian and Edwardian literature as the "Psychical Research Society". The term psychical was adopted to distinguish the purported phenomena from those classified as psychic, (that is simply mental processes such as thought, memory, etc.) and the SPR were to introduce a number of other neologisms which have entered the English language, such as 'telepathy', which was coined by Frederic Myers.
The Society is run by a President and a Council of twenty members, and is open to interested members of the public to join. The organisation is based at 49 Marloes Road, Kensington, London, with a library and office open to members, and with large book and archival holdings in Cambridge University Library, Cambridgeshire, England. It publishes the peer reviewed quarterly Journal of the Society for Psychical Research (JSPR), the irregular Proceedings and the magazine Paranormal Review. It holds an annual conference, regular lectures and two study days per year and supports the LEXSCIEN on-line library project.
The psychical researcher Harry Price joined the SPR in 1920 and because of his knowledge in conjuring had debunked fraudulent mediums but in direct contrast to sceptics such as Harry Houdini, Price endorsed some mediums that he believed were genuine. Price formed an organization in 1926 called the National Laboratory of Psychical Research as a rival to the Society for Psychical Research. Price had a number of disputes with the SPR, most notably over the mediumship of Rudi Schneider. In the 1920s and early 1930s Price tested Rudi at his laboratory.
In April 1932, Price discovered that members of his council had been conducting secret negotiations with Rudi to set up experiments with the SPR. The SPR member John L. Randall wrote "Since it was Price who had brought Rudi to England in the first instance, the attempt to set up further experiments behind his back was seen by him as an act of betrayal." Rudi claimed he could levitate objects but according Price a photograph taken on April 28, 1932 showed that Rudi had managed to free his arm to move a handkerchief from the table. After this, many scientists considered Rudi to be exposed as a fraud. Price wrote the findings of other experiments should be revised due to the evidence showing how Rudi could free himself from the control.
After Price had exposed Rudi, various scientists such Karl Przibram and the magician Henry Evans wrote to Price telling him that they agreed that Rudi would evade control during his séances and congratulated Price on the success of unmasking the fraud. In opposition, SPR members who were highly critical of Price, supported Rudi's mediumship and promoted a conspiracy theory that Price had hoaxed the photograph. SPR member Anita Gregory claimed Price had deliberately faked the photograph to discredit SPR research and ruin Rudi's reputation. However, the photographic expert Vernon Harrison testified that the photograph was genuine.
According to John L. Randall there was direct evidence of "dirty tricks" played upon Price by members of the SPR. On October 9, 1931, a past president of the SPR William Henry Salter visited the Borley Rectory in an attempt to persuade the Rector Lionel Foyster, to sever his links with Price and work with the SPR instead. After Price's death in 1948 Eric Dingwall, Kathleen M. Goldney, and Trevor H. Hall, three members of the Society for Psychical Research, two of whom had been Price's most loyal associates, investigated his claims about Borley. Their findings were published in a 1956 book, The Haunting of Borley Rectory, which concluded Price had fraudulently produced some of the phenomena. The "Borley Report", as the SPR study has become known, stated that many of the phenomena were either faked or due to natural causes such as rats and the strange acoustics attributed to the odd shape of the house. In their conclusion, Dingwall, Goldney, and Hall wrote "when analysed, the evidence for haunting and poltergeist activity for each and every period appears to diminish in force and finally to vanish away." Robert Hastings was one of the few SPR researchers to defend Price. Price's literary executor Paul Tabori and Peter Underwood have also defended Price against accusations of fraud. A similar approach was made by Ivan Banks in 1996. Michael Coleman in an SPR report in 1997 wrote Price's defenders are unable to rebut the criticisms convincingly.
At a séance in the house of the solicitor John Snaith Rymer in Ealing in July 1855, the SPR member Frederick Merrifield observed that a "spirit-hand" was a false limb attached on the end of Daniel Dunglas Home's arm. Merrifield also claimed to have observed Home use his foot in the séance room.
Writing in the Journal of the Society for Psychical Research, Count Petrovsky Petrovo-Solovo described séances in which Home was caught using his feet to create supposed spirit effects. Home wore thin shoes, easy to take off and draw on, and also cut socks that left the toes free. "At the appropriate moment he takes off one of his shoes and with his foot pulls a dress here, a dress there, rings a bell, knocks one way and another, and, the thing done, quickly puts his shoe on again." Home held a séance for Eugénie de Montijo, and positioned himself between Montijo and Napoleon III. One of the séance sitters known as General Felury suspected Home was utilizing trickery and asked to leave but returned unobserved to watch from another door behind Home. He saw Home slip his foot from his shoe and touch the arm of the Empress, who believed it to be one of her dead children. The observer stepped forward and revealed the fraud, and Home was conducted out of the country. "The order was to keep the incident secret."
In a series of experiments in London at the house of William Crookes in February 1875, Anna Eva Fay managed to fool Crookes into believing she had genuine psychic powers. Fay confessed in 1913 to Eric Dingwall that she had duped Crookes and other scientists. She was investigated by the magician Harry Houdini, to whom after her retirement in 1924 confessed fraud to 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 by SPR members 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 a medium Crookes supported had been "trained in the arts of the séance" by Herne and was repeatedly exposed as a fraudulent medium.
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.
In 1876, William Eglinton was exposed as a fraud when the 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 séance a spirit named "Yohlande" materialized, a sitter grabbed it and was revealed to be the medium Mme. d'Esperance herself.
Johann Karl Friedrich Zöllner, Professor of Physics and Astronomy at the University of Leipzig conducted several controlled experiments, using the medium Henry Slade, to evaluate his claims of paranormal ability in 1877. Slade failed some of the tests carried out under controlled conditions but still succeeded in fooling Zöllner in several other attempts. The SPR member Hereward Carrington in his book The Physical Phenomena of Spiritualism (1907) revealed the fraudulent methods (with diagrams of the rope tricks) that Slade used in the Zöllner experiments.
The Creery Sisters (Mary, Alice, Maud, Kathleen, and Emily) were tested in 1881 by the SPR members William F. Barrett, Frederic Myers, and Edmund Gurney who announced them to have genuine psychic ability. In 1888, the Creery sisters were caught utilizing signal codes and they confessed to fraud.
The medium William Eglinton performed slate writing mediumship and his leading critics were the psychical researchers Eleanor Sidgwick and Richard Hodgson. In 1886 and 1887 a series of publications by S. J. Davey, Hodgson and Sidgwick in the Journal of the Society for Psychical Research exposed the slate writing tricks of Eglinton.
The psychical researcher and SPR member Charles Richet with Oliver Lodge, Frederic Myers and Julian Ochorowicz investigated the medium Eusapia Palladino in the summer of 1894 at his house in the Ile Roubaud in the Mediterranean. Richet claimed furniture moved during the séance and that some of the phenomena was the result of a supernatural agency. However, Richard Hodgson claimed there was inadequate control during the séances and the precautions described did not rule out trickery. Hodgson wrote all the phenomena "described could be account for on the assumption that Eusapia could get a hand or foot free." Lodge, Myers and Richet disagreed, but Hodgson was later proven correct in the Cambridge sittings as Palladino was observed to have used tricks exactly the way he had described them.
In July 1895, Palladino was invited to England to Myers' house in Cambridge for a series of investigations into her mediumship. According to reports by the investigators Myers and Oliver Lodge, all the phenomena observed in the Cambridge sittings were the result of trickery. Her fraud was so clever, according to Myers, that it "must have needed long practice to bring it to its present level of skill." In the Cambridge sittings the results proved disastrous for her mediumship. During the séances Palladino was caught cheating in order to free herself from the physical controls of the experiments. Palladino was found liberating her hands by placing the hand of the controller on her left on top of the hand of the controller on her right. Instead of maintaining any contact with her, the observers on either side were found to be holding each other's hands and this made it possible for her to perform tricks. Richard Hodgson had observed Palladino free a hand to move objects and use her feet to kick pieces of furniture in the room. Because of the discovery of fraud, the British SPR investigators such as Henry Sidgwick and Frank Podmore considered Palladino's mediumship to be permanently discredited and because of her fraud she was banned from any further experiments with the SPR in Britain.
In the British Medical Journal on November 9, 1895 an article was published titled Exit Eusapia!. The article questioned the scientific legitimacy of the SPR for investigating Eusapia Palladino a medium who had a reputation of being a fraud and imposture. Part of the article read "It would be comic if it were not deplorable to picture this sorry Egeria surrounded by men like Professor Sidgwick, Professor Lodge, Mr. F. H. Myers, Dr. Schiaparelli, and Professor Richet, solemnly receiving her pinches and kicks, her finger skiddings, her sleight of hand with various articles of furniture as phenomena calling for serious study." This caused Henry Sidgwick to respond in a published letter to the British Medical Journal, November 16, 1895. According to Sidgwick SPR members had exposed the fraud of Palladino at the Cambridge sittings, Sidgwick wrote "Throughout this period we have continually combated and exposed the frauds of professional mediums, and have never yet published in our Proceedings, any report in favour of the performances of any of them." The response from the Journal questioned why the SPR wastes time investigating phenomena that are the "result of jugglery and imposture" and not urgently concerning the welfare of mankind.
In 1898, Myers was invited to a series of séances in Paris with Charles Richet. In contrast to the previous séances in which he had observed fraud he claimed to have observed convincing phenomena. Sidgwick reminded Myers of Palladino's trickery in the previous investigations as "overwhelming" but Myers did not change his position. This enraged Richard Hodgson, then editor of SPR publications to ban Myers from publishing anything on his recent sittings with Palladino in the SPR journal. Hodgson was convinced Palladino was a fraud and supported Sidgwick in the "attempt to put that vulgar cheat Eusapia beyond the pale." It wasn't until the 1908 sittings in Naples that the SPR reopened the Palladino file.
In the late 19th century Douglas Blackburn and George Albert Smith were endorsed as genuine psychics by the Society for Psychical Research. Smith even became an SPR member himself and the private secretary to the Honorary Secretary Edmund Gurney from 1883 to 1888. However, Blackburn later confessed to fraud:
For nearly thirty years the telepathic experiments conducted by Mr. G. A. Smith and myself have been accepted and cited as the basic evidence of the truth of thought transference... ...the whole of those alleged experiments were bogus, and originated in the honest desire of two youths to show how easily men of scientific mind and training could be deceived when seeking for evidence in support of a theory they were wishful to establish.
In 1905, Eva Carrière held a series of séances at Villa Carmen and sitters were invited. In these séances she claimed to materialize a spirit called Bien Boa a 300-year-old Brahmin Hindu, however, photographs taken of Boa looked like the figure was made from a large cardboard cutout. In other sittings Charles Richet reported that Boa was breathing, had moved around the room and had touched him, a photograph taken revealed Boa to be a man dressed up in a cloak, helmet and beard. A newspaper article in 1906 had revealed that an Arab coachman known as Areski who had previously worked at the villa had been hired to play the part of Bien Boa and that the entire thing was a hoax. Areski wrote that he made his appearance into the room by a trapdoor. Carrière had also admitted to being involved with the hoax.
In 1906, William Hope tricked William Crookes (a past president of the SPR) with a fake spirit photograph of his wife. Oliver Lodge revealed there had been obvious signs of double exposure, the picture of Lady Crookes had been copied from a wedding anniversary photograph, however, Crookes was a convinced spiritualist and claimed it was genuine evidence for spirit photography. Lodge who served as president of the London-based Society for Psychical Research from 1901 to 1903 was also a spiritualist. Charles Arthur Mercier a specialist in insanity wrote in his book Spiritualism and Sir Oliver Lodge (1917) that Lodge had been duped into believing mediumship by trickery and his Spiritualist views were based on assumptions and not scientific evidence.
In 1908, the Society for Psychical Research appointed a committee of three to examine Palladino in Naples. The committee comprised Mr. Hereward Carrington, investigator for the American Society for Psychical Research and an amateur conjurer; Mr. W. W. Baggally, also an investigator and amateur conjurer of much experience; and the Hon. Everard Feilding, who had an extensive training as investigator and "a fairly complete education at the hands of fraudulent mediums." Three adjoining rooms on the fifth floor of the Hotel Victoria were rented. The middle room where Feilding slept was used in the evening for the séances. In the corner of the room was a séance cabinet created by a pair of black curtains to form an enclosed area that contained a small round table with several musical instruments. In front of the curtains was placed a wooden table. During the séances, Palladino would sit at this table with her back to the curtains. The investigators sat on either side of her, holding her hand and placing a foot on her foot. Guest visitors also attended some of the séances; the Feilding report mentions that Professor Bottazzi and Professor Galeotti were present at the fourth séance, and a Mr. Ryan was present at the eighth séance.
Although the investigators caught Palladino cheating, they were convinced Palladino produced genuine supernatural phenomena such as levitations of the table, movement of the curtains, movement of objects from behind the curtain and touches from hands. SPR member Frank Podmore in his book The Newer Spiritualism (1910) wrote a comprehensive critique of the Feilding report. According to Podmore the report provided insufficient information at crucial moments and the witness accounts from the investigators contained contradictions and inconsistencies on who was holding Palladino's feet and hands. Podmore discovered various statements by the investigators conflicted with each other on what they claimed to have observed. Some of the statements were also written days after the events took place. Podmore wrote the report "at almost every point leaves obvious loopholes for trickery." During the séances the long black curtains were often intermixed with Palladino's long black dress. Palladino told Professor Bottazzi the black curtains were "indispensable." Researchers have suspected Palladino used the curtain to conceal her feet.
The psychologist C. E. M. Hansel criticized the Feilding report based on the conditions of the séances being susceptible to trickery. Hansel noted that they were performed in semi-dark conditions, held in the late night or early morning introducing the possibility of fatigue and the "investigators had a strong belief in the supernatural, hence they would be emotionally involved."
In 1910, Everard Feilding returned to Naples, without Hereward Carrington and W. W. Baggally. Instead, he was accompanied by his friend, William S. Marriott, a magician of some distinction who had exposed psychic fraud in Pearson's Magazine. His plan was to repeat the famous earlier 1908 Naple sittings with Palladino. Unlike the 1908 sittings which had baffled the investigators, this time Feilding and Marriott detected her cheating, just as she had done in the US. 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."
Eric Dingwall observed the medium Bert Reese in New York and claimed to have discovered his billet reading tricks. 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. The SPR member Edmund Fournier d'Albe investigated the medium Kathleen Goligher. On 22 July 1921 he observed Goligher moving the séance table with her foot. He also discovered her "ectoplasm" was made from muslin. During a séance d'Albe had observed white muslin between Goligher's feet.
In 1922, Eric Dingwall and Harry Price re-published an anonymous work written by a former medium entitled Revelations of a Spirit Medium 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 the same year Price, James Seymour, Dingwall and William Marriott exposed the fraud of the spirit photographer William Hope. 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."
In 1925, SPR member 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.
In 1934, SPR members Oliver Gatty and Theodore Besterman examined the mediumship of Rudi Schneider and published a paper which concluded there is "no good evidence that Rudi Schneider possesses supernormal powers". According to the magician John Booth the stage mentalist David Devant managed to fool a number of people into believing he had genuine psychic 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. 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 Soal-Goldney experiment (1941-1943) on ESP was fraudulent as it was revealed Samuel Soal had altered and faked the data. Soal was originally accused of fraud by sceptics and scientists such as C. E. M. Hansel and George Price who proposed various ways that he could have cheated. Direct evidence of fraud came from SPR member Betty Marwick who discovered that Soal had not used the method of random selection of numbers as he had claimed. Marwick showed that there had been manipulation of the score sheets "all the experiments reported by Soal had thereby been discredited."
In 1954, the SPR member 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). 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. Eugene 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.
In the early 1980s the SPR member Brian Inglis was involved in a dispute with the sceptic Ruth Brandon over the mediumship of Daniel Dunglas Home in the New Scientist magazine. In 1988, the magician Bob Couttie criticized Inglis for deliberately ignoring evidence of fraud in mediumship. Couttie wrote Inglis had not familiarized himself with magician techniques. The parapsychologist D. Scott Rogo complained that Inglis "had a bad habit in his writing of suppressing negative information about psychics and researchers he favored by failing to note cases of fraud that were uncovered."
In 1992, Richard Wiseman analyzed the Feilding report of Palladino 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. Paul Kurtz suggested that Carrington could have been Palladino's secret accomplice. Kurtz found it suspicious that he was raised as her manager after the séances in Naples. Carrington was also absent on the night of the last séance. However, Massimo Polidoro and Gian Marco Rinaldi who analyzed the Feilding report came to the conclusion that no secret accomplice was needed as Palladino during the 1908 Naples séances could have produced the phenomena by using her foot.
Ivor Lloyd Tuckett wrote that even though the SPR have collected some valuable work, most of its active members have "no training in psychology fitting them for their task, and have been the victims of pronounced bias, as sometimes they themselves have admitted." Trevor Hall an ex-member of the Society for Psychical Research criticized SPR members as "credulous and obsessive wish... to believe." Hall also claimed SPR members "lack knowledge of deceptive methods."
Magicians and sceptics have criticized spiritualist SPR members such as William Crookes, Oliver Lodge and Cesare Lombroso for not educating themselves in conjurer tricks and being duped by fraudulent mediums. On this subject, Ivor Lloyd Tuckett wrote:
The fact of the matter is that scientific men, who are accustomed to accurate laboratory conditions and instruments, which do not lie or give rise to error — at any rate consciously are no match for the subtle degrees of deception practiced by media like Home, Moses and Eusapia.
Edward Clodd claimed the SPR members William F. Barrett and Oliver Lodge were incompetent researchers to detect fraud and wrote their spiritualist beliefs were based on magical thinking and primitive superstition. Clodd analyzed the SPR and saw nothing more than "barbaric spiritual philosophy", he mocked the language of SPR members "subliminal consciousness" and "telepathic energy" as a disguise for "bastard supernaturalism." The psychologist Millais Culpin noted that SPR members had not educated themselves about psychological factors.
The sceptic and physicist Victor J. Stenger wrote:
Investigations of mediums continued into the twentieth century, and the SPR and ASPR on occasion exposed blatant cases of fraud even their own credulous memberships could not swallow. But their journals have never succeeded in achieving a high level of credibility in the eyes of the rest of the scientific community. Today the psychical research journals continue as forums for believers to press their ideas, to respond to the attacks of sceptics, and to attack the sceptics in return. Nothing is wrong with that, as long as the editorial bias is admitted. The volumes occasionally contain some respectable studies, but most articles usually begin with the assumption that psychic phenomena are demonstrated realities. Since this is a belief and not an empirical fact, one might be justified in viewing the SPR and ASPR today as religious rather than scientific institutions.
The psychologist David Marks has written that paranormal researchers such as those in the SPR have failed to produce a single repeatable demonstration of the paranormal in over 100 years and described psychical research as a pseudoscience an "incoherent collection of belief systems steeped in fantasy, illusion and error." In 2003, James Alcock highlighted various problems with psychical research including failure to produce a single paranormal phenomenon that can be independently replicated by neutral researchers and lack of progress in over a century of formal research.
A psychological study involving 174 members of the Society for Psychical Research completed a delusional ideation questionnaire and a deductive reasoning task. As predicted, the study showed that "individuals who reported a strong belief in the paranormal made more errors and displayed more delusional ideation than sceptical individuals". There was also a reasoning bias which was limited to people who reported a belief in, rather than experience of, paranormal phenomena. The results suggested that reasoning abnormalities may have a causal role in the formation of paranormal belief.

Home's usual phenomena were messages, the moving of objects (presumably at a distance), and the playing of an accordion which he held with one hand under the shadow of the table. But from an early date in America he had been accustomed occasionally to "materialise" hands (as it was afterwards called). The sitters would, in the darkness, faintly see a ghostly hand and arm, or they might feel the touch of an icy limb. Mr. Merrifield and the other sitters saw a "spirit-hand" stretch across the faintly lit space of the window. But Mr. Merrifield says that Home sat, or crouched, low in a low chair, and that the "spirit-hand" was a false limb on the end of Home's arm. At other times, he says, he saw that Home was using his foot."

General Fleury came forward and described what he had seen. The following day Home was embarked at Calais conducted by two agents; the order was to keep the incident secret."

In 1910 he had been asked by the SPR to take part in a series of sittings with the Italian medium Eusapia Palladino, and had concluded that all he had seen could be attributed to fakery. That same year he published four articles for Pearson's magazine in which he detailed and duplicated in photographs various tricks of self-claimed psychics and mediums."
