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. It claims to be the "first society to conduct organised scholarly research into human experiences that challenge contemporary scientific models."[1] 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.[2]

History[edit]

Frank Podmore, a notable sceptical member

Origins[edit]

The Society for Psychical Research (SPR) originated from a discussion between journalist Edmund Rogers and the physicist William F. Barrett in autumn 1881. This led to a conference on the 5 and 6 January 1882 at the headquarters of the British National Association of Spiritualists which the foundation of the Society was proposed.[3] The committee included Barrett, Rogers, Stainton Moses, Charles Massey, Edmund Gurney, Hensleigh Wedgwood and Frederic W. H. Myers.[4] The SPR was formally constituted on the 20 February 1882 with philosopher Henry Sidgwick as its first president.[5][6][7]

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."[8]

Other early members included the chemist William Crookes, physicist Oliver Lodge, Nobel laureate Charles Richet and psychologist William James.[9]

Areas of study included thought-transference, mediumship, Reichenbach phenomena, apparitions and haunted houses and the physical phenomena associated with séances.[10][11]

Research[edit]

Much of the early work involved investigating, exposing and in some cases duplicating fake phenomena. In the late 19th century, SPR investigations into séance phenomena led to the exposure of many fraudulent mediums.[12]

Richard Hodgson 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.[13] Among the phenomena that Hodgson investigated was the alleged miraculous Mahatma letters which were said to magically appear over a four-year period in a cabinet in the Shrine Room at the Theosophical headquarters in Madres.[14] 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.[14] Hodgson's report was later examined by Vernon Harrison who outlined flaws in his work. Harrison concluded that the letters were forgeries but were not written by Blavatsky but by ex-employees for revenge.[15]

Among the first important works was the two-volume publication in 1886, Phantasms of the Living co-authored by Gurney, Myers and Frank Podmore.[16]

In 1886 and 1887 a series of publications by S. J. Davey, Hodgson and Sidgwick in the SPR journal exposed the slate writing tricks of the medium William Eglinton.[17] Hodgson with his friend, S. J. Davey had staged fake séances for educating the public (including SPR members). Davey gave sittings under an assumed name, duplicating the phenomena produced by 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 Stainton Moses resigned from the SPR.[17]

In 1891, Alfred Russel Wallace requested for the Society to properly investigate spirit photography.[18] Eleanor Sidgwick responded with a critical paper in the SPR which cast doubt on the subject and revealed the fraudulent methods that spirit photographers such as Édouard Isidore Buguet, Frederic Hudson and William H. Mumler had utilized.[19]

In 1894, the Census of Hallucinations was published which sampled 17, 000 people. Out of these, 1, 684 persons admitted to having experienced a hallucination of an apparition.[20]

The SPR investigated many spiritualist mediums such as Eva Carrière and Eusapia Palladino.[21] Due to the exposure of William Hope and other fraudulent mediums, 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.[22] Science historian William Hodson Brock has noted that "By the 1900s most avowed spiritualists had left the SPR and gone back to the BNAS (the London Spiritualist Alliance since 1884), having become upset by the sceptical tone of most of the SPR's investigations."[23]

During the early twentieth century, the SPR studied a series of automatic scripts and trance utterances from a group of automatic writers, known as the cross-correspondences.[24] The SPR were to introduce a number of neologisms which have entered the English language, such as 'telepathy', which was coined by Frederic Myers.[25]

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.[26] 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[1][27] and supports the LEXSCIEN on-line library project.[28]

Famous cases investigated by the Society include Borley Rectory and the Enfield Poltergeist.

Criticism from sceptics[edit]

Edward Clodd, a critic of the SPR

Sceptics have criticized the SPR for essentially having a secret religious motive. After the publication of Charles Darwin's On the Origin of Species (1859), it was difficult for those with a scientific education to retain a belief in tenets of the Judeo-Christian religion. Early SPR members like Henry Sidgwick and Frederic W. H. Myers hoped to cling to something spiritual through psychical research.[29][30]

The sceptic and physicist Victor J. Stenger has written:

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.[31]

Ivor Lloyd Tuckett an author of an early sceptical work on psychical research 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."[32] Trevor H. 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."[33]

Rationalist writer Edward Clodd claimed that the SPR members William F. Barrett and Oliver Lodge were incompetent researchers to detect fraud and suggested that their spiritualist beliefs were based on magical thinking and primitive superstition.[34] 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."[35]

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."[36]

Psychological study[edit]

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.[37]

They used a number of tricks facilitated by darkness: sleight of hand was used to manipulate objects and touch people eager to make contact with deceased loved ones; flour or white lines would give the illusion of spectral white hands or faces; accomplices were even stashed under tables or in secret rooms to lent support in the plot... As the investigations of the SPR, and other skeptics, were made public, many fraudulent mediums saw their careers ruined and many unsuspecting clients were enraged at the deception perpetrated."

But Myers, among others, had no such intention and cherished no such illusion. He knew that the primary aim of the Society was not objective experimentation but the establishment of telepathy. To understand why this was so it is necessary to realize the position in which so many educated and intelligent people found themselves during the 1870s and later in Victorian England. With the emergence of new scientific concepts touching the origin of man and his place in the universe, the very foundations of their religious beliefs began to give way."
