Telepathy (from Ancient Greek τῆλε ( têle ) 'distant' and πάθος / -πάθεια ( páthos/-pátheia ) ' feeling , perception , passion , affliction , experience ') 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 W. H. Myers , a founder of the Society for Psychical Research (SPR), and has remained more popular than the earlier expression thought-transference .

Richard Hodgson , a member of the SPR and a research worker of paranormal phenomena, was sent to India. Hodgson's task was to examine if
166-633: A myth in psychological literature. Psychologists Stephen Hupp and Jeremy Jewell have noted that all experiments on the subject have failed to provide any scientific evidence for telepathy between twins . According to Hupp and Jewell there are various behavioral and genetic factors that contribute to the twin telepathy myth "identical twins typically spend a lot of time together and are usually exposed to very similar environments. Thus, it's not at all surprising that they act in similar ways and are adept at anticipating and forecasting each other's reactions to events." A 1993 study by Susan Blackmore investigated

The receiver is then required to receive information from the sender. The nature of the information may vary between experiments. The Ganzfeld experiment studies that were examined by Ray Hyman and Charles Honorton had methodological problems that were well documented. Honorton reported only 36% of

Science writer Martin Gardner suggested that the possibility of sensory leakage during the experiment had not been ruled out: In the first place, an intuitive wife, who knows her husband intimately, may be able to guess with a fair degree of accuracy what he is likely to draw—particularly if the picture is related to some freshly recalled event

Telepathy is a common theme in science fiction . According to historians such as Roger Luckhurst and Janet Oppenheim the origin of the concept of telepathy in Western civilization can be traced to the late 19th century and

George Albert Smith and Douglas Blackburn were claimed to be genuine psychics by the Society for Psychical Research but Blackburn 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
747-639: A mass resignation of eighty-four members of the Society for Psychical Research, as they believed the Society was opposed to spiritualism. 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." The Society has been criticized by both spiritualists and skeptics. Prominent spiritualists at first welcomed

A review of their book in the American Journal of Orthopsychiatry cast doubt on their experiment, noting "the study was published five years after it was conducted, arouses suspicion on the validity of the conclusions. In 1948, on the BBC radio Maurice Fogel made the claim that he could demonstrate telepathy. This intrigued the journalist Arthur Helliwell who wanted to discover his methods. He found that Fogel's mind reading acts were all based on trickery as he relied on information about members of his audience before

In an experiment (Schienle et al . 1996) 22 believers and 20 skeptics were asked to judge the covariation between transmitted symbols and the corresponding feedback given by a receiver. According to the results the believers overestimated

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 5 and 6 January 1882 at the headquarters of the British National Association of Spiritualists , at which the foundation of the Society was proposed. The committee included Barrett, Rogers, Stainton Moses , Charles Massey , Edmund Gurney , Hensleigh Wedgwood and Frederic W. H. Myers . The SPR

Psychological research has also revealed other explanations such as confirmation bias , expectancy bias , sensory leakage , subjective validation , and wishful thinking . Virtually all of the instances of more popular psychic phenomena, such as mediumship , can be attributed to non-paranormal techniques such as cold reading . Magicians such as Ian Rowland and Derren Brown have demonstrated techniques and results similar to those of popular psychics, albeit without claiming paranormal skills. They have identified, described, and developed psychological techniques of cold reading and hot reading . The notion of telepathy
1660-434: Is highly probable that they will sometimes think the same thought at the same time." Graham Reed , a specialist in anomalistic psychology , noted that experiments into telepathy often involve the subject relaxing and reporting the 'messages' to consist of colored geometric shapes. Reed wrote that these are a common type of hypnagogic image and not evidence for telepathic communication. Outside of parapsychology, telepathy

Physicist John Taylor has written that the experiments that have been claimed by parapsychologists to support evidence for the existence of telepathy are based on the use of shaky statistical analysis and poor design, and attempts to duplicate such experiments by the scientific community have failed. Taylor also wrote the arguments used by parapsychologists for

A variety of tests have been performed to demonstrate telepathy, but there is no scientific evidence that

This similarity might explain how an individual might come to the conclusion that he or she were experiencing telepathy. Thought insertion/removal is a symptom of psychosis , particularly of schizophrenia , schizoaffective disorder or substance-induced psychosis . Psychiatric patients who experience this symptom falsely believe that some of their thoughts are not their own and that others (e.g., other people, aliens, demons or fallen angels, or conspiring intelligence agencies, or artificial intelligences) are putting thoughts into their minds (thought insertion). Some patients feel as if thoughts are being taken out of their minds or deleted (thought removal). Schizophrenic patients suffering from

When using them, one individual is designated

Rhine 's experiments with Zener cards were discredited due to the discovery that sensory leakage or cheating could account for all his results such as the subject being able to read the symbols from the back of the cards and being able to see and hear the experimenter to note subtle clues. Once Rhine took precautions in response to criticisms of his methods, he

Statistically, the receiver has a 20% chance of randomly guessing the correct symbol, so to demonstrate telepathy, they must repeatedly score a success rate that is significantly higher than 20%. If not conducted properly, this method

As the physical sciences made significant advances, scientific concepts were applied to mental phenomena (e.g., animal magnetism ), with the hope that this would help to understand paranormal phenomena.

She attempted to duplicate 290 pictures which were drawn by her husband. Sinclair claimed Mary successfully duplicated 65 of them, with 155 "partial successes" and 70 failures. However, these experiments were not conducted in

The psychologist James Alcock has written the dream telepathy experiments at Maimonides have failed to provide evidence for telepathy and "lack of replication is rampant."

In a series of experiments the EM levels were many orders of magnitude lower than calculated and no paranormal effects were observed. Both Taylor and Balanovski wrote their results were

Another example is the experiment carried out by the author Harold Sherman with the explorer Hubert Wilkins who carried out their own experiment in telepathy for five and a half months starting in October 1937. This took place when Sherman was in New York and Wilkins was in the Arctic . The experiment consisted of Sherman and Wilkins at the end of each day to relax and visualise

Although Fogel managed to fool some people into believing he could perform genuine telepathy, the majority of his audience knew he was a showman. In a series of experiments Samuel Soal and his assistant K. M. Goldney examined 160 subjects over 128,000 trials and obtained no evidence for the existence of telepathy. Soal tested Basil Shackleton and Gloria Stewart between 1941 and 1943 in over five hundred sittings and over twenty thousand guesses. Shackleton scored 2890 compared with

Storm et al . published a response to Hyman claiming the ganzfeld experimental design has proved to be consistent and reliable but parapsychology

Because of the flaws, Honorton agreed with Hyman the 42 Ganzfeld studies could not support the claim for the existence of psi. Possibilities of sensory leakage in the Ganzfeld experiments included the receivers hearing what was going on in the sender's room next door as the rooms were not soundproof and

Hyman discovered flaws in all of the 42 Ganzfeld experiments and to access each experiment, he devised a set of 12 categories of flaws. Six of these concerned statistical defects, the other six covered procedural flaws such as inadequate documentation , randomization and security as well as possibilities of sensory leakage. Over half of

Woolley, who was at the time the Research Officer for the SPR, arranged a telepathy experiment in which radio listeners were asked to take part. The experiment involved 'agents' thinking about five selected objects in an office at Tavistock Square , whilst listeners on
6391-513: Was famous for performing blindfolded feats such as identifying a hidden object in a room that a person had picked out or asking someone to imagine a murder scene and then attempt to read the subject's thoughts and identify the victim and reenact the crime. Cumberland claimed to possess no genuine psychic ability and his thought-reading performances could only be demonstrated by holding the hand of his subject to read their muscular movements. He came into dispute with psychical researchers associated with
6474-474: Was formally constituted on 20 February 1882 with philosopher Henry Sidgwick as its first president. 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." In 1882 Mary Everest Boole became
6557-666: Was founded, with the establishment of thought-transference—already rising within measurable distance of proof—as its primary aim.” Defenders of the SPR have stated in reply that “a ‘will to believe’ in post-mortem survival, telepathy and other scientifically unpopular notions, does not necessarily exclude a ‘will to know’ and thus the capacity for thorough self-criticism , methodological rigour and relentless suspicion of errors.” The skeptic and physicist Victor J. Stenger has written: The SPR ... on occasion exposed blatant cases of fraud even their own credulous memberships could not swallow. But their journals have never succeeded in achieving
6640-476: Was received negatively by the scientific mainstream, though Gurney and Podmore provided a defense of the society's early work in this area in mainstream publications. The SPR "devised methodological innovations such as randomized study designs" and conducted "the first experiments investigating the psychology of eyewitness testimony (Hodgson and Davey, 1887), [and] empirical and conceptual studies illuminating mechanisms of dissociation and hypnotism" In 1894,
6723-419: Was right at the chance expectation of 25%. For targets that appeared twice the hit rate crept up to 28%. For those that occurred three times it was 38%, and for those targets that occurred six or more times, the hit rate was 52%. Each time a videotape is played its quality can degrade. It is plausible then, that when a frequently used clip is the target for a given session, it may be physically distinguishable from
6806-661: Was seriously damaged due to the Hodgson Report. Society for Psychical Research The Society for Psychical Research ( SPR ) is a nonprofit organisation in the United Kingdom. Its stated purpose is to understand events and abilities commonly described as psychic or paranormal . It describes itself as the "first society to conduct organised scholarly research into human experiences that challenge contemporary scientific models." It does not, however, since its inception in 1882, hold any corporate opinions: SPR members assert
6889-530: Was unable to find any high-scoring subjects. Due to the methodological problems, parapsychologists no longer utilize card-guessing studies. Parapsychological studies into dream telepathy were carried out at the Maimonides Medical Center in Brooklyn, New York led by Stanley Krippner and Montague Ullman . They concluded the results from some of their experiments supported dream telepathy. However,
