Rosenhan's first pseudopatient said he was picking up radio signals
On 19 January 1973, Science published nine pages that would shake American psychiatry for half a century. The title is a slogan: "On Being Sane in Insane Places". The author, David Rosenhan, a professor of psychology and law at Stanford, reported that eight mentally healthy people had got themselves admitted to twelve psychiatric hospitals spread across five states, on both coasts, by reporting one symptom and one only: unfamiliar voices, of the same sex as the patient, repeating the words "empty", "hollow", "thud". Every one of them was admitted. Eleven of the twelve admissions produced a diagnosis of schizophrenia; the twelfth, at the only private hospital in the sample, manic depressive psychosis. The stays ran from 7 to 52 days, 19 on average. Nearly 2,100 pills were handed out, two swallowed. Every pseudopatient, Rosenhan wrote, walked back out with a diagnosis of schizophrenia carrying the notation "in remission". And in conclusion: "It is clear that we cannot distinguish the sane from the insane in psychiatric hospitals."
The whole force of the demonstration rests on a single sentence of the protocol: beyond the alleged symptom and the falsification of name, occupation and employer, "no further alterations of person, history, or circumstances were made". The significant events of each participant's life, the article specifies, were presented as they had actually happened. If people who tell the truth about everything except three words end up committed, then the diagnosis says nothing about the patient and everything about the place. That sentence is the first thing to collapse.
The Haverford file
David Rosenhan died in 2012, leaving behind a personal archive: correspondence, a journal, and the unfinished manuscript of a book he never delivered to his publisher. A close friend, Florence Keller, opened it up to the journalist Susannah Cahalan, who had come in the first place to write the glorious history of the study.
The first pseudopatient, the one the notes call "David Lurie", is Rosenhan himself. The Science article says so without naming him: "I was the first pseudopatient and my presence was known to the hospital administration and chief psychologist." He was teaching at Swarthmore College at the time, and he spent nine days at Haverford State Hospital, in Pennsylvania, in February 1969.
The medical record Cahalan turned up looks nothing like the published protocol. Rosenhan did not allege three words and nothing else. He told the doctors he had stopped sleeping, that he was cold all over, that he had not worked in six months, that he was sensitive to radio signals, and that he had suicidal thoughts. He explained that he had held a copper pot against his ears to muffle the voices. The physician who examined him also recorded grimacing and tics. The historian Andrew Scull, who worked through the same documents, comes away with the same list.
None of this appears in the Science article. The difference is not cosmetic. A man who says he picks up radio signals, who seals his ears under copper and who admits to suicidal ideation is not a healthy subject being labelled over three words: he is a clinical picture that any admissions ward would take seriously. The published protocol states the opposite, in black and white, and the entire conclusion rests on that statement.
The doctored case summary
The most quoted passage in the article is an excerpt from a case record. Rosenhan presents the anonymised case of a man close to his mother and distant from his father in childhood, in whom the two relationships reverse during adolescence: the father becomes a close friend while the bond with the mother cools. The marriage is described as warm, the arguments rare, the children almost never punished. "Surely there is nothing especially pathological about such a history", Rosenhan comments.
Then comes the discharge summary: "This white 39-year-old male... manifests a long history of considerable ambivalence in close relationships, which begins in early childhood. A warm relationship with his mother cools during his adolescence. A distant relationship with his father is described as becoming very intense. Affective stability is absent. His attempts to control emotionality with his wife and children are punctuated by angry outbursts and, in the case of the children, spankings." Rosenhan's comment: "The facts of the case were unintentionally distorted by the staff to achieve consistency with a popular theory of the dynamics of a schizophrenic reaction."
That 39-year-old patient, according to Cahalan, is Rosenhan. She compared the published excerpt with the original documents and concluded that the Science article contains inaccurate or fabricated quotations drawn from the psychiatric records. If she is right, Rosenhan doctored a piece of evidence, then used the doctored piece to demonstrate that the staff distorted the facts. Richard Griggs, Jenna Blyler and Sherri Jackson summed the affair up for Scholarship of Teaching and Learning in Psychology, online as early as 2020, under a title that tells you the rest: "Scientific integrity in remission".
The ninth participant, demoted to footnote 6
Rosenhan writes "Eight sane people gained secret admission to 12 different hospitals", and hangs a footnote marker on that sentence. Note 6, at the end of the article, reads: "Data from a ninth pseudopatient are not incorporated in this report because, although his sanity went undetected, he falsified aspects of his personal history, including his marital status and parental relationships. His experimental behaviors therefore were not identical to those of the other pseudopatients."
That ninth participant is Harry Lando, then a doctoral student, today a professor of psychology at the University of Minnesota. He spent 19 days at the US Public Health Service Hospital in San Francisco, and he too walked out with a mistaken diagnosis of schizophrenia. Asked about it by Cahalan, he sums the experience up in one word: positive. "The hospital seemed to have a calming effect. Someone might come in agitated and then fairly quickly they would tend to calm down. It was a benign environment." He published his own account in 1976 in Professional Psychology, under the title "On Being Sane in Insane Places: A Supplemental Report".
The stated grounds for exclusion do not survive the comparison. Lando is said to have falsified his marital status and his parental relationships; Rosenhan invented an occupation, six months out of work, and half a dozen symptoms the published protocol denies having alleged. The only documented breach of protocol that ever cost anyone their place in the sample, then, belongs to the participant whose data contradicted the thesis. That is how Lando reads it too: "Rosenhan was interested in diagnosis, and that's fine, but you've got to respect and accept the data, even if the data are not supportive of your preconceptions."
The six who were never found
Rosenhan describes his sample with precision: a psychology graduate student in his twenties, then seven older and "established" people, among them three psychologists, a paediatrician, a psychiatrist, a painter and a housewife. Three women, five men. All under pseudonyms.
Cahalan spent years looking for them. She put out an appeal in The Lancet Psychiatry in May 2017, under the title "In search of Insane Places". She hired a private detective, who got no further than she had. In the end she identified only two: Rosenhan, and Bill Underwood, then a graduate student at Stanford, whose account, she writes, does not square with the description the article gives of him. Hence the question she ends up putting in black and white, without being able to settle it: some of the other six, perhaps all of them, may never have existed.
Andrew Scull, a historian of psychiatry at the University of California, San Diego, went back through the documents Cahalan passed on to him. His conclusion, published in History of Psychiatry in 2023, sits in his title: "Rosenhan revisited: successful scientific fraud".
What psychiatry had already answered
The rebuttal did not wait for 2019. On 27 April 1973, a little over three months after publication, Science ran fifteen readers' letters under the heading "Psychiatric Diagnosis", followed by a reply from Rosenhan. In October 1975, the Journal of Abnormal Psychology gave the study four critical papers back to back, by Weiner, Spitzer, Crown and Millon, before another Rosenhan rejoinder.
The harshest is Robert Spitzer's, who would soon be chairing the DSM-III task force. His title announces the charge: "On pseudoscience in science, logic in remission, and psychiatric diagnosis". In it he takes up an objection from Seymour Kety: "If I were to drink a quart of blood and, concealing what I had done, come to the emergency room of any hospital vomiting blood, the behavior of the staff would be quite predictable. If they labeled and treated me as having a bleeding peptic ulcer, I doubt that I could argue convincingly that medical science does not know how to diagnose that condition." A diagnosis built on what the patient reports does not become absurd because the patient lied. As for the "in remission" notation, which Rosenhan offered as proof of clinical blindness, Spitzer's argument turns it around: it is the written trace of a staff that had ended up registering the absence of symptoms. Hence the pun in the title, which diagnoses the study itself with logic in remission. Spitzer extended the critique in 1976 in the Archives of General Psychiatry.
Those objections stayed inside specialist journals; the Science article reached the general public. For Scull, it played a decisive part in the American Psychiatric Association's decision to revise its manual, and the DSM-III of 1980, at 494 pages, nearly four times the thickness of the previous edition, launched a revolution whose effects are still with us. The legend outlived its refutation, and there is nothing accidental about the asymmetry: three words are enough to tell the study, it takes a great deal more to take it apart. In 2017, Jared Bartels and Daniel Peters reviewed twelve psychopathology textbooks for Teaching of Psychology: half of them covered the study, all of those presented it as a demonstration of the power of psychiatric labels, and only two mentioned any criticism at all. The authors closed by urging teachers and textbook writers to go and read the critical literature. Half a century after it appeared, Rosenhan's article is still cited hundreds of times a year.
