As founder and director of the University of Virginia School of Medicine's Division of Perceptual Studies (originally named "Division of Personality Studies"), which investigates the paranormal, Stevenson became known for his research into cases he considered suggestive of reincarnation – the idea that emotions, memories, and even physical bodily features can be passed on from one incarnation to another. In the course of his forty years doing international fieldwork, he researched three thousand cases of children who claimed to remember past lives. His position was that certain phobias, philias, unusual abilities and illnesses could not be fully explained by genetics or the environment. He believed that, in addition to genetics and the environment, reincarnation might possibly provide a third, contributing factor.

Stevenson helped to found the Society for Scientific Exploration in 1982, and was the author of around three hundred papers and fourteen books on reincarnation, including Twenty Cases Suggestive of Reincarnation (1966), Cases of the Reincarnation Type (four volumes, 1975-1983) and European Cases of the Reincarnation Type (2003). His 1997 work Reincarnation and Biology: A Contribution to the Etiology of Birthmarks and Birth Defects reported two hundred cases in which birthmarks and birth defects seemed to correspond in some way to a wound on the deceased person whose life the child recalled. He wrote a shorter version of the same research for the general reader, Where Reincarnation and Biology Intersect (1997).

Stevenson was cautious in making claims about reincarnation. He emphasized that the information he collected only suggests that reincarnation is possible but does not prove that it occurs. He did, however, believe he had produced a body of evidence for reincarnation that must be taken seriously. He said, "[T]he evidence is not flawless and it certainly does not compel such a belief. Even the best of it is open to alternative interpretations, [but] one can only censure those who say there is no evidence whatever."

Reaction to his work was mixed. In an obituary for Stevenson in The New York Times, Margalit Fox wrote that Stevenson's supporters saw him as a misunderstood genius, that his detractors regarded him as earnest but gullible, but that most scientists had simply ignored his research. Stevenson based his research on anecdotal case reports that were dismissed by the scientific community as unreliable because Stevenson did no controlled experimental work. His case reports were also criticized as they contained errors and omissions. Critics contend that ultimately Stevenson's conclusions are undermined by confirmation bias, mistakes, and motivated reasoning. Supporters of his work include Jim B. Tucker, a psychiatrist and colleague at the University of Virginia who now heads the division Stevenson founded.

Background

Personal life and education

Ian Stevenson was born in Montreal and raised in Ottawa, one of three children. His father, John Stevenson, was a Scottish lawyer who was working in Ottawa as the Canadian correspondent for The Times of London or The New York Times. His mother, Ruth, had an interest in theosophy and an extensive library on the subject, to which Stevenson attributed his own early interest in the paranormal. As a child he was often bedridden with bronchitis, a condition that continued into adulthood and engendered in him a lifelong love of books. According to Emily Williams Kelly, a colleague of his at the University of Virginia, he maintained a list of the books he had read, which numbered 3,535 between 1935 and 2003.

He studied medicine at St. Andrews University in Scotland from 1937 to 1939, but had to complete his studies in Canada because of the outbreak of the Second World War. He graduated from McGill University with a B.S.c. in 1942 and an M.D. in 1943. He was married to Octavia Reynolds from 1947 until her death in 1983. In 1985, he married Dr. Margaret Pertzoff (1926–2009), professor of history at Randolph-Macon Woman's College. She did not share his views on the paranormal, but tolerated them with what Stevenson called "benevolent silences".

Early career

After graduating, Stevenson conducted research in biochemistry. His first residency was at the Royal Victoria Hospital in Montreal (1944–1945), but his lung condition continued to bother him, and one of his professors at McGill advised him to move to Arizona for his health. He took up a residency at St. Joseph's Hospital in Phoenix, Arizona (1945–1946). After that, he held a fellowship in internal medicine at the Alton Ochsner Medical Foundation in New Orleans, became a Denis Fellow in Biochemistry at Tulane University School of Medicine (1946–1947), and a Commonwealth Fund Fellow in Medicine at Cornell University Medical College and New York Hospital (1947–1949). He became a U.S. citizen in 1949.

Emily Williams Kelly writes that Stevenson became dissatisfied with the reductionism he encountered in biochemistry, and wanted to study the whole person. He became interested in psychosomatic medicine, psychiatry and psychoanalysis, and in the late 1940s, worked at New York Hospital exploring psychosomatic illness and the effects of stress, and in particular why, for example, one person's response to stress might be asthma and another's high blood pressure.

He taught at Louisiana State University School of Medicine from 1949 to 1957 as assistant, then associate, professor of psychiatry.

In the 1950s, he met Aldous Huxley (1894–1963), known for his advocacy of psychedelic drugs, and studied the effects of L.S.D. and mescaline, one of the first academics to do so. Ian Stevenson, in his course of studies, tried and studied L.S.D. himself, describing three days of "perfect serenity". He wrote that at the time he felt he could "never be angry again", but added, "As it happens that didn't work out, but the memory of it persisted as something to hope for."

From 1951, he studied psychoanalysis at the New Orleans Psychoanalytic Institute and the Washington Psychoanalytic Institute, graduating from the latter in 1958, a year after being appointed head of the department of psychiatry at the University of Virginia. The orthodoxy within psychiatry and psychoanalysis at the time held that the personality is less plastic in one's early years, so when he argued against this in his paper "Is the human personality more plastic in infancy and childhood?" (American Journal of Psychiatry, 1957) his paper angered many of his colleagues. He wrote that their response prepared him for the rejection he experienced over his work on the paranormal.

Stevenson's interest in reincarnation research

Stevenson described as the leitmotif of his career his interest in why one person would develop one disease, and another something different. He came to believe that neither environment nor heredity could account for certain fears, illnesses and special abilities, and that some form of personality or memory transfer might provide a third type of explanation. He acknowledged, however, the absence of evidence of a physical process by which a personality could survive death and transfer to another body, and he was careful not to commit himself fully to the position that reincarnation occurs. He argued only that his case studies could not, in his view, be explained by environment or heredity, and that "reincarnation is the best – even though not the only – explanation for the stronger cases we have investigated." He said in 1974, looking back on his work:

[W]hat I do believe is that, of the cases we now know, reincarnation--at least for some--is the best explanation that we have been able to come up with. There is an impressive body of evidence and it is getting stronger all the time. I think a rational person, if he wants, can believe in reincarnation on the basis of evidence.

In 1958 and 1959, Stevenson contributed several articles and book reviews to Harper's about parapsychology, including psychosomatic illness and extrasensory perception, and in 1958, he submitted the winning entry to a competition organized by the American Society for Psychical Research, in honor of the philosopher William James (1842–1910). The prize was for the best essay on "paranormal mental phenomena and their relationship to the problem of survival of the human personality after bodily death". Stevenson's essay, "The Evidence for Survival from Claimed Memories of Former Incarnations" (1960), reviewed forty-four published cases of people, mostly children, who claimed to remember past lives. It caught the attention of Eileen J. Garrett (1893–1970), the founder of the Parapsychology Foundation, who gave Stevenson a grant to travel to India to interview a child who was claiming to have past-life memories. According to Jim Tucker, Stevenson found twenty-five other cases in just four weeks in India and was able to publish his first book on the subject in 1966, Twenty Cases Suggestive of Reincarnation.

Chester Carlson (1906–1968), the inventor of xerography, offered further financial help. Jim Tucker writes that this allowed Stevenson to step down as chair of the psychiatry department and set up a separate division within the department, which he called the Division of Personality Studies, later renamed the Division of Perceptual Studies.

When Carlson died in 1968, he left $1,000,000 to the University of Virginia to continue Stevenson's work. The bequest caused controversy within the university because of the nature of the research, but the donation was accepted, and Stevenson became the first Carlson Professor of Psychiatry.

The bequest from Chester Carlson allowed Stevenson to travel extensively, sometimes as much as 55,000 miles a year, collecting around three thousand case studies based on interviews with children from Africa to Alaska.

Case studies

Overview

The cases Stevenson investigated show these typical features:

1. Starting at an age between two and four, a child spontaneously begins narrating details of a "previous life".
2. The child speaks increasingly about this, and with greater clarity, until the ages of five or six. Then the child speaks less about the "previous life".
3. By the age of eight, the child generally stops speaking about the past life.
4. The child shows behavior unexpected for him or her but consistent with the behavior of a particular deceased person. For example, the child may have a fear of guns or have special interests or appetites.
5. In many cases, the child may have a birthmark or congenital birth defect whose location and appearance correspond with fatal wounds on the body of the "previous person". A high number of children allude to a past-life violent death.
6. In some cultures, the "previous person", before dying, predicts his or her next life. The previous person may also appear in a dream to the expectant mother to announce an intention to be born of her.
7. After the age of ten, the child usually develops normally.

Stevenson gave these cases the term "cases of the reincarnation type" (CORT).

What makes these cases noteworthy is that Stevenson reported that in many cases the statements made by the children can be extensively corroborated. In such cases, he said, research shows that the person whose life the child seems to remember did in fact exist and that many of the child's statements about that person's experiences, acts, and relationships turn out to be correct.

Stevenson also reported other, behavioral features typical for such cases:

1. The children speak of previous lives as if speaking from their own memories
2. Children request to go to their "previous home", either to visit or to stay permanently.
3. In the presence of persons related to the "previous person", the children behave in a manner fitting for the "previous relationship", according to the relationship and according to social customs.
4. Again in relation with people (or objects) related to the "previous person", children respond with emotions one might expect from that person, such as tears, joy, affection, fear, or resentment.
5. Children show mannerisms, habits, or skills suitable for the previous person or that the previous person was known to have had.

In one case of claimed reincarnation, as Stevenson recounted it, a newborn girl in Sri Lanka screamed whenever she was carried near a bus or a bath. When she was old enough to talk, he said, she recounted a previous life as a girl of 8 or 9 who drowned after a bus knocked her into a flooded rice paddy. Later investigation found the family of just such a dead girl living four or five kilometers away. The two families, Stevenson said, were believed to have had no contact.

According to journalist Tom Shroder, "In interviewing witnesses and reviewing documents, Stevenson searched for alternate ways to account for the testimony: that the child came upon the information in some normal way, that the witnesses were engaged in fraud or self-delusion, that the correlations were the result of coincidence or misunderstanding. But in scores of cases, Stevenson concluded that no normal explanation sufficed."

Stevenson's Reincarnation and Biology: A Contribution to the Etiology of Birthmarks and Birth Defects (1997)—a two-volume work of 2,268 pages—examined 225 cases of children claiming past-life memories who also had birthmarks or birth defects that matched the lives remembered. And in some cases autopsy reports and photos confirmed the existence of corresponding injuries on the dead person's body. A Burmese girl who spoke about the life of a girl run over by a train was born without her lower right leg. A Thai boy who said he recalled the life of someone shot was born with birthmarks resembling bullet entrance and exit wounds. An Indian child who recounted living as a boy who had lost his right-hand fingers to a fodder-chopping machine was born with boneless stubs for fingers on his right hand only, a birth defect so rare that Stevenson was unable to find a single published case of it.

Reception

Criticism

The Journal of the American Medical Association referred to Stevenson's Cases of the Reincarnation Type (1975) as a "painstaking and unemotional" collection of cases that were "difficult to explain on any assumption other than reincarnation". In September 1977, the Journal of Nervous and Mental Disease devoted most of one issue to Stevenson's research. Writing in the journal, the psychiatrist Harold Lief described Stevenson as a methodical investigator and added, "Either he is making a colossal mistake, or he will be known (I have said as much to him) as 'the Galileo of the 20th century'." The issue proved popular: the journal's editor, the psychiatrist Eugene Brody, said he had received 300–400 requests for reprints.

Despite this early interest, most scientists ignored Stevenson's work. According to his New York Times obituary, his detractors saw him as "earnest, dogged but ultimately misguided, led astray by gullibility, wishful thinking and a tendency to see science where others saw superstition". Critics suggested that the children or their parents had deceived him, that he was too willing to believe them, and that he had asked them leading questions. Robert Todd Carroll wrote in his Skeptic's Dictionary that Stevenson's results were subject to confirmation bias, in that cases not supportive of the hypothesis were not presented as counting against it. Leonard Angel, a philosopher of religion, told The New York Times that Stevenson did not follow proper standards. "[B]ut you do have to look carefully to see it; that's why he's been very persuasive to many people."

In an article in Skeptical Inquirer Angel examined Stevenson's Twenty Cases Suggestive of Reincarnation (1974) and concluded that the research was so poorly conducted as to cast doubt on all Stevenson's work. He says that Stevenson failed to clearly and concisely document the claims made before attempting to verify them. Among a number of other faults, Angel says, Stevenson asked leading questions and did not properly tabulate or account for all erroneous statements. Angel writes:

"In sum, Stevenson does not skillfully record, present, or analyze his own data. If a case regarded by Stevenson to be among the strongest of his cases — the only case of 20 that had its purported verifications conducted by Stevenson himself — falls apart under scrutiny as badly as the Imad Elawar case does, it is reasonable to conclude that the other cases, in which data were first gathered by untrained observers, are even less reliable than this one."

Skeptics have written that Stevenson's evidence was anecdotal and by applying Occam's razor there are prosaic explanations for the cases without invoking the paranormal. Psychologist and neurologist Terence Hines has written:

"The major problem with Stevenson's work is that the methods he used to investigate alleged cases of reincarnation are inadequate to rule out simple, imaginative storytelling on the part of the children claiming to be reincarnations of dead individuals. In the seemingly most impressive cases Stevenson (1975, 1977) has reported, the children claiming to be reincarnated knew friends and relatives of the dead individual. The children's knowledge of facts about these individuals is, then, somewhat less than conclusive evidence for reincarnation."

Robert Baker wrote that many alleged past-life experiences can be explained in terms of known psychological factors. Baker attributed the recalling of past lives to a mixture of cryptomnesia and confabulation. British author and independent researcher Ian Wilson argued that a large number of Stevenson's cases consisted of poor children remembering wealthy lives or belonging to a higher caste. He speculated that such cases may represent a scheme to obtain money from the family of the alleged former incarnation.

The philosopher C.T.K. Chari of Madras Christian College in Chennai, a specialist in parapsychology, argued that Stevenson was naive and that the case studies were undermined by his lack of local knowledge. Chari wrote that many of the cases had come from societies, such as that of India, where people believed in reincarnation, and that the stories were simply cultural artifacts; he argued that, for children in many Asian countries, the recall of a past life is the equivalent of an imaginary playmate. The philosopher Keith Augustine made a similar argument.

Responding to this cultural argument, Stevenson said that it was precisely those societies that listened to children's claims about past lives, which in Europe or North America would normally be dismissed without investigation. To address the cultural concern, he wrote European Cases of the Reincarnation Type (2003), which presented forty cases he had examined in Europe. Moreover, Joseph Prabhu, professor emeritus of philosophy and religion at California State University, wrote that it is not true "that these cases are mainly to be found in cultures, where the belief in reincarnation is prevalent. In July 1974 Stevenson's colleague at the University of Virginia, J. G. Pratt, carried out a census of Stevenson's cases and found that of the 1339 cases then in Stevenson's file, 'the United States has the most, with 324 cases (not counting American Indian and Eskimo) and the next five countries in descending order are Burma (139 cases), India (135), Turkey (114), and Great Britain (111).'"

The philosopher Paul Edwards, editor-in-chief of Macmillan's Encyclopedia of Philosophy, became Stevenson's chief critic. From 1986 onwards, he devoted several articles to Stevenson's work, and discussed Stevenson in his Reincarnation: A Critical Examination (1996). He argued that Stevenson's views were "absurd nonsense" and that when examined in detail his case studies had "big holes" and "do not even begin to add up to a significant counterweight to the initial presumption against reincarnation". Stevenson, Edwards wrote, "evidently lives in a cloud-cuckoo-land".

Champe Ransom, whom Stevenson hired as an assistant in the 1970s, wrote an unpublished report about Stevenson's work, which Edwards cites in his Immortality (1992) and Reincarnation (1996). According to Ransom, Edwards wrote, Stevenson asked the children leading questions, filled in gaps in the narrative, did not spend enough time interviewing them, and left too long a period between the claimed recall and the interview; it was often years after the first mention of a recall that Stevenson learned about it. In only eleven of the 1,111 cases Ransom looked at had there been no contact between the families of the deceased and of the child before the interview; in addition, according to Ransom, seven of those eleven cases were seriously flawed. He also wrote that there were problems with the way Stevenson presented the cases, in that he would report his witnesses' conclusions, rather than the data upon which the conclusions rested. Weaknesses in cases would be reported in a separate part of his books, rather than during the discussion of the cases themselves. Ransom concluded that it all amounted to anecdotal evidence of the weakest kind.

Edwards cited the case of Corliss Chotkin, Jr., in Angoon, Alaska, where Stevenson relied entirely on the word of one woman, the niece of the person whose life Chotkin seemed to remember, a fisherman called Victor Vincent. Edwards wrote that, among the many weaknesses in the case, the family were religious believers in reincarnation, Chotkin had birthmarks that were said to have resembled scars that Vincent had but Stevenson had not seen Vincent's scars, and all the significant details relied on the niece. Edwards said that Stevenson offered no information about her, except that several people told him she had a tendency, as Stevenson put it, to embellish or invent stories. Edwards wrote that similar weaknesses could be found in all Stevenson's case studies.

Edwards charged that Stevenson referred to himself as a scientist but did not act like one. According to Edwards, he failed to respond to, or even mention, significant objections; the large bibliography in Stevenson's Children Who Remember Previous Lives (1987) does not include one paper or book from his opponents.

Stevenson wrote an introduction to a book, Second Time Round (1975), in which Edward Ryall, an Englishman, told of what he believed to be his memories of a past life as John Fletcher, a man who was born in 1645 in Taunton, England, and died forty years later near his home in Westonzoyland, Somerset. Stevenson investigated the case and discovered that some of the historical features from Ryall's book were accurate. Stevenson wrote, "I think it most probable that he has memories of a real previous life and that he is indeed John Fletcher reborn, as he believes himself to be". In 1976, however, John Taylor discovered that none of the available church records at the Westonzoyland church from 1645 to 1685 had entries for births, marriages, or deaths for the name Fletcher. Since no trace of the name could be found, he concluded that no man called John Fletcher actually existed and that the supposed memories were a fantasy Ryall had developed over the years. Stevenson later altered his opinion about the case. In his book European Cases of the Reincarnation Type, he wrote, "I can no longer believe that all of Edward Ryall's apparent memories derive from a previous life, because some of his details are clearly wrong," but he still suggested that Ryall acquired some information about 17th-century Somerset by paranormal means.

Concessions from critics

Ian Wilson, one of Stevenson's critics, acknowledged that Stevenson had brought "a new professionalism to a hitherto crank-prone field". Paul Edwards wrote that Stevenson "has written more fully and more intelligibly in defense of reincarnation than anybody else". Though faulting Stevenson's judgment, Edwards wrote: "I have the highest regard for his honesty. All of his case reports contain items that can be made the basis of criticism. Stevenson could easily have suppressed this information. The fact that he did not speaks well for his integrity."

Support

Caitlin Gibson wrote in The Washington Post, "Stevenson's reputation — even among those skeptical of the topic — was that of a serious and scrupulous scientist, someone who openly examined both the strengths and weaknesses of the cases he chronicled."

Stevenson's colleague Jim B. Tucker wrote that when Stevenson began studying cases of children who report memories of previous lives, he "largely created a new area of scientific research".

Stevenson, Tucker wrote, "considered himself a man of science and always strove to use a scientific attitude, being careful and methodical in trying to sort out exactly what had happened in the various cases. He never assumed they meant reincarnation had occurred."

Lee Irwin, professor of religious studies at the College of Charleston, wrote in the journal Religions, "In many ways, Stevenson's research marks a watershed in reincarnation theory, as it moves the center of focus away from a religious context entirely and relocates the center in an academic, evidential program of investigation."

Reviewing Stevenson's work favorably in an article on the Scientific American website, Jesse Bering, professor of science communication, wrote in 2013: "Towards the end of her own storied life, the physicist Doris Kuhlmann-Wilsdorf—whose groundbreaking theories on surface physics earned her the prestigious Heyn Medal from the German Society for Material Sciences, surmised that Stevenson's work had established that 'the statistical probability that reincarnation does in fact occur is so overwhelming ... that cumulatively the evidence is not inferior to that for most if not all branches of science.' "

Bering also registered his own views: "Some cases were much stronger than others, but I must say, when you actually read them firsthand, many are exceedingly difficult to explain away by rational, non-paranormal means. Much of this is due to Stevenson's own exhaustive efforts to disconfirm the paranormal account. 'We can strive toward objectivity by exposing as fully as possible all observations that tend to weaken our preferred interpretation of the data,' he wrote. 'If adversaries fire at us, let them use ammunition that we have given them.' And if truth be told, he excelled at debunking the debunkers."

Cognitive scientist David E. Presti and neuroscientist and parapsychologist Edward F. Kelly wrote, "Stevenson was a meticulous scientist and conservative in his interpretation of data. At the same time, he was a true visionary, and courageous in his study of phenomena that lie outside the current scientific mainstream." Neuroscientist Ernesto Bonilla wrote, "The cases that have been described so far, isolated or combined, do not provide irrefutable proof of reincarnation, but they supply evidence that suggest its reality."

Writing about empirical evidence for reincarnation, philosopher Joseph Prabhu cited Stevenson's investigations as the best-known example of "a considerable amount of scientific data garnered according to the strictest standards".

Another philosopher, David Ray Griffin, wrote that Stevenson "produced impeccable and extensive studies, based on evidence from a wide variety of cultures, which have provided strong evidence that reincarnation at least sometimes occurs".

Theologian Paul Badham and his co-author Linda Badham wrote, "Professor Stevenson is especially noted for his caution in an area where accusations of fraud (whether conscious or unconscious, on the part of either experimenter or subjects) are so easily made. Moreover, his attention to detail and the mass of evidence he accumulates so painstakingly and meticulously place his work on quite a distinct level."

Stevenson also won praise from fellow members of the medical profession. Harold Lief, M.D., emeritus professor of psychiatry at the University of Pennsylvania, wrote of Stevenson as "a careful, meticulous researcher and scholar". Stevenson, he wrote, was "positively obsessive" in the way he went about collecting data. Eugene Brody, M.D., editor of The Journal of Nervous and Mental Disease, was also impressed by Stevenson's "persistent and patient data-gathering".

Remi J. Cadoret, M.D., wrote in The American Journal of Psychiatry that Stevenson's European Cases of the Reincarnation Type "provides an introduction to an exciting range of [unusual] phenomena and furnishes an inspiring example of a painstaking protocol to sift facts from fancy."

Lester S. King, M.D., historian, author, pathologist, and past senior editor of The Journal of the American Medical Association, reviewed the first volume of Cases of the Reincarnation Type for the Journal. King wrote, "He may not convince skeptics, but he has placed on record a large amount of data that cannot be ignored."

Dismissal without consideration

According to an obituary in The Telegraph (UK), Stevenson's greatest frustration "was not that people dismissed his theories, but that so few bothered even to read the evidence he had so painstakingly assembled". Stevenson's colleague Jim Tucker told The BMJ (the British medical journal), "His case reports are incredibly detailed. He put as much on the record as possible. It's often dismissed without looking at it."

Openness

Carl Sagan, in his book The Demon-Haunted World, wrote that there were three claims in the parapsychology field that, though he didn't think them likely to be valid and though experimental support for them was still dubious, he thought "might be true" and that "deserve serious study". Among these three, he wrote, apparently referring to Stevenson's investigations, were cases of young children who "report the details of a previous life, which upon checking turn out to be accurate and which they could not have known about in any other way than reincarnation".

Citing Stevenson's works (among others), Sam Harris wrote in his book The End of Faith:

There also seems to be a body of data attesting to the reality of psychic phenomena, much of which has been ignored by mainstream science. The dictum that "extraordinary claims require extraordinary evidence" remains a reasonable guide in these areas, but this does not mean that the universe isn't far stranger than many of us suppose. It is important to realize that a healthy, scientific skepticism is compatible with a fundamental openness of mind.

Stance on "past-life regressions"

Stevenson generally took a dim view of hypnotic "past-life regression". He wrote, "Although widely exploited by lay hypnotists and even by a few psychologists who should know better, hypnotic regression of 'previous lives' (with rare exceptions) generates only fantasies."

His colleague Emily Williams Kelly wrote, "His empirical approach made him deeply skeptical of purported accounts of previous lives obtained by hypnosis or 'past life regression.' He kept a file in his office which he labeled 'Extravagant Claims,' containing numerous Thomas Jeffersons, Mary Magdalenes, Napoleons, and Josephines, and he would speculate amusingly to colleagues about what would happen if they were all to be locked in a room together."

Xenoglossy

Although Stevenson focused on cases of children who seemed to spontaneously remember past lives, and although he was generally skeptical of "past-life regressions", he studied two cases in which adults under hypnosis seemed to remember a past life and show rudimentary use of a language they had not learned in the present life. Stevenson called this phenomenon "xenoglossy". The linguist Sarah Thomason, critiquing these cases, wrote that Stevenson is "unsophisticated about language" and that the cases are unconvincing. Thomason concluded, "the linguistic evidence is too weak to provide support for the claims of xenoglossy." William J. Samarin, a linguist from the University of Toronto, wrote that Stevenson corresponded with linguists in a selective and unprofessional manner. He said that Stevenson corresponded with one linguist in a period of six years "without raising any discussion about the kinds of thing that linguists would need to know". Another linguist, William Frawley, wrote, "Stevenson does not consider enough linguistic evidence in these cases to warrant his metaphysics."

On the other hand, the linguist Paul Meara wrote, "One's first instinct is to dismiss these accounts as nonsense, but Ian Stevenson makes a very convincing case." That the subjects of Stevenson's xenoglossy cases somehow survived bodily death and were able to express themselves in new physical bodies is a conclusion many readers would find unacceptable, he wrote, "but the arguments put forward to support it in the final chapter [of Stevenson's book Unlearned Language] are not easily dismissed, and even the most sceptical reader will find that this book provides food for a good deal of thought."

Retirement

Child psychiatrist Jim Tucker continues Stevenson's work.

Stevenson stepped down as director of the Division of Perceptual Studies in 2002, although he continued to work as Research Professor of Psychiatry. Bruce Greyson, editor of the Journal of Near-Death Studies, became director of the division. Jim Tucker, the department's associate professor of psychiatry and neurobehavioral sciences, continued Stevenson's research with children, examined in Tucker's book, Life Before Life: A Scientific Investigation of Children's Memories of Previous Lives (2005).

Death and experiment

Stevenson died of pneumonia on February 8, 2007, at his home in Charlottesville, Virginia. In his will he endowed the Stevenson Chair in Philosophy and History of Science including Medicine, at McGill University Department of Social Studies of Medicine.

As one experiment to test for personal survival of bodily death, in the 1960s Stevenson set a combination lock using a secret word or phrase and placed it in a filing cabinet in the department, telling his colleagues he would try to pass the code to them after his death. Emily Williams Kelly told The New York Times: "Presumably, if someone had a vivid dream about him, in which there seemed to be a word or a phrase that kept being repeated—I don't quite know how it would work—if it seemed promising enough, we would try to open it using the combination suggested."
