Parapsychology is the study of alleged psychic phenomena ( extrasensory perception , telepathy , precognition , clairvoyance , psychokinesis (also called telekinesis), and psychometry ) and other paranormal claims, for example, those related to near-death experiences , synchronicity , apparitional experiences , etc. Criticized as being a pseudoscience , the majority of mainstream scientists reject it. Parapsychology has also been criticized by mainstream critics for claims by many of its practitioners that their studies are plausible despite a lack of convincing evidence after more than a century of research for the existence of any psychic phenomena.
64-416: The Institut Métapsychique International (IMI) is a French parapsychological organization that studies paranormal phenomena. It was created in 1919 by Jean Meyer, Gustav Geley and Professor Rocco Santoliquido. Notable past presidents have included Charles Richet (1930-1935) and René Warcollier (1950-1962). Eugéne Osty served as a director (1925-1938). This parapsychology -related article

Rhine stated in his first book, Extrasensory Perception (1934), that after 90,000 trials, he felt ESP is "an actual and demonstrable occurrence". Irish medium and parapsychologist Eileen J. Garrett was tested by Rhine at Duke University in 1933 with Zener cards. Rhine placed certain symbols on

One of the first students at Newnham College in Cambridge, in 1876 she married (and became converted to feminism by) the philosopher Henry Sidgwick . In 1880 she became Vice-Principal of Newnham under the founding Principal Anne Clough , succeeding as principal on Clough's death in 1892. In 1890 Sidgwick was elected to the Ladies Dining Society that had been founded by Louise Creighton and Kathleen Lyttleton . Other members included

Casinos for this reason retire dice often, but at Duke, subjects continued to try for the same effect on the same dice over long experimental runs. Not surprisingly, PK appeared at Duke and nowhere else. Parapsychologists and skeptics criticized the Ownbey-Zirkle ESP experiment at Duke. Ownbey would attempt to send ESP symbols to Zirkle, who would guess what they were. The pair were placed in adjacent rooms, unable to see each other, and an electric fan

When Rhine took precautions in response to criticisms of his methods, he failed to find any high-scoring subjects. Another criticism, made by chemist Irving Langmuir , among others, was one of selective reporting . Langmuir stated that Rhine did not report scores of subjects that he suspected were intentionally guessing wrong and that this, he felt, biased
384-449: A famous ESP experiment at Duke University. Warner and Raible locked a subject in a room with a switch controlling a signal light elsewhere, which she could signal to guess the card. Ten runs with ESP packs of cards were used, and she achieved 93 hits (43 more than chance). Weaknesses with the experiment were later discovered. The duration of the light signal could be varied so that the subject could call for specific symbols. Certain symbols in

Pickering reported a similar experiment in which they tested 36 subjects over 23,384 trials, which did not obtain above-chance scores. In 1881, Eleanor Sidgwick revealed the fraudulent methods that spirit photographers such as Édouard Isidore Buguet , Frederic Hudson , and William H. Mumler had utilized. During the late nineteenth century, many fraudulent mediums were exposed by SPR investigators. Largely due to

Sidgwick regarded Eglinton to be nothing more than a clever conjurer . Due to the critical papers, Stainton Moses and other prominent spiritualist members resigned from the Society for Psychical Research. In 1891, Alfred Russel Wallace requested for

Rhine, however, Ownbey sent them to Turner. Critics pointed out this invalidated the results as she could have simply written her own record to agree with the other. When the experiment was repeated and the records were sent to Rhine, the scores dropped to average. Lucien Warner and Mildred Raible performed

Because of the methodological problems, parapsychologists no longer utilize card-guessing studies. Rhine's experiments into psychokinesis (PK) were also criticized. John Sladek wrote: His research used dice, with subjects 'willing' them to fall

Parapsychology Parapsychology research rarely appears in mainstream scientific journals ; a few niche journals publish most papers about parapsychology. The term parapsychology was coined in 1889 by philosopher Max Dessoir as the German parapsychologie . It was adopted by J. B. Rhine in the 1930s as a replacement for
896-400: Is a technique used to test individuals for telepathy. The technique—a form of moderate sensory deprivation —was developed to quickly quiet mental "noise" by providing mild, unpatterned stimuli to the visual and auditory senses. The visual sense is usually isolated by creating a soft red glow which is diffused through half ping-pong balls placed over the recipient's eyes. The auditory sense
960-1105: Is derived from ψ psi, the 23rd letter of the Greek alphabet and the initial letter of the Greek: ψυχή psyche , "mind, soul". The term was coined by biologist Bertold Wiesner , and first used by psychologist Robert Thouless in a 1942 article published in the British Journal of Psychology . The Parapsychological Association divides psi into two main categories: psi-gamma for extrasensory perception and psi-kappa for psychokinesis. In popular culture, "psi" has become more and more synonymous with extraordinary psychic , mental , and " psionic " abilities and powers. In 1853, chemist Robert Hare conducted experiments with mediums and reported positive results. Other researchers such as Frank Podmore highlighted flaws in his experiments, such as lack of controls to prevent trickery. Agenor de Gasparin conducted early experiments into table-tipping . For five months in 1853, he declared

After thousands of card runs, James Charles Crumbaugh failed to duplicate the results of Rhine. In 1938, the psychologist Joseph Jastrow wrote that much of the evidence for extrasensory perception collected by Rhine and other parapsychologists

2688-418: The experiments a success, being the result of an " ectenic force ". Critics noted that the conditions were insufficient to prevent trickery. For example, the sitters may have moved the table with their knees, and no experimenter was simultaneously watching above and below the table. The German astrophysicist Johann Karl Friedrich Zöllner tested the medium Henry Slade in 1877. According to Zöllner, some of

The Society for Psychical Research (SPR) was founded in London in 1882. Its formation was the first systematic effort to organize scientists and scholars to investigate paranormal phenomena. Early membership included philosophers , scholars, scientists, educators and politicians , such as Henry Sidgwick , Arthur Balfour , William Crookes , Rufus Osgood Mason , and Nobel Laureate Charles Richet .

The surge in paranormal research continued into the 1980s: the Parapsychological Association reported members working in more than 30 countries. For example, research was carried out and regular conferences held in Eastern Europe and the former Soviet Union although the word parapsychology was discarded in favor of the term psychotronics. The main promoter of psychotronics
