For most of the twentieth century the stress-and-acid model was wrong: peptic ulcers were not a verdict on the patient’s worry, ambition or diet but, in roughly 90% of duodenal and up to 80% of gastric cases, a curable infection with Helicobacter pylori. From the Croatian-Austrian surgeon Dragutin (Carl) Schwarz’s 1910 dictum Ohne sauren Magensaft kein peptisches Geschwür — “no acid, no ulcer” — physicians taught that an ulcer reflected too much stress and spice. The promise was a coherent story; the delivered reality was some seventy years of treatments that suppressed acid and managed symptoms while never touching the cause.
The reversal began in Perth, Western Australia. In 1979 pathologist J. Robin Warren saw small curved bacteria colonising the lower stomach of biopsy patients, always alongside inflammation — against the textbook certainty that gastric acid sterilised the stomach. With clinician Barry Marshall, Warren cultured the organism in 1982 (a chance success after an Easter-weekend plate was left incubating past the usual 48 hours), and the pair published in The Lancet in 1983 and 1984. The establishment did not believe them, so in late July 1984 Marshall drank a broth of the bacterium, developed acute gastritis within days, documented it by endoscopy, and cured it with antibiotics — satisfying Koch’s postulates on his own stomach lining.
Displacement was total but slow. A US NIH Consensus panel (12–14 Feb 1994) accepted that H. pylori caused most peptic ulcers and that a short antibiotic course could cure a disease previously managed for life. On 3 October 2005 the Nobel Assembly awarded Warren and Marshall the Prize in Physiology or Medicine “for their discovery of the bacterium Helicobacter pylori and its role in gastritis and peptic ulcer disease” — the formal certificate of a dogma revoked.
This dossier files the stress-and-acid model as TH-002 not as fraud — it was sincere, taught in good faith — but as the family’s purest specimen of an honest, near-universal theory displaced by a confirmed mechanism: institutional confidence, not dishonesty, was the obstacle, and the cost was measured in years of curable suffering prolonged.
The doctrine that the mind buries traumatic memories intact and that a skilled therapist can retrieve them was, for roughly fifteen years, treated as settled clinical fact — and on 13 May 1994 a Napa County jury found it was negligence. In Ramona v. Isabella, the jury voted 10–2 that counselor Marche Isabella and psychiatrist Dr. Richard Rose had reinforced false memories of childhood sexual abuse in their patient Holly Ramona, and awarded her father Gary Ramona $500,000. The promise of recovered-memory therapy had been that hypnosis, guided imagery, dream work, and “truth-serum” sodium-amytal interviews could surface authentic buried trauma; the documented reality was that those same techniques manufactured detailed, sincerely held memories of events that had never occurred. The gap between the promise and the harm was not measured in a single ruined family but in thousands.
The technique was never validated before it was deployed at scale. It extrapolated from a Freudian premise — that the psyche represses unbearable experience and that symptoms (an eating disorder, depression, anxiety) are coded messages from sealed trauma. Bestsellers such as The Courage to Heal (1988) told readers that if they suspected they had been abused, they probably had, and that absence of memory was itself evidence of repression. Inside that loop, therapist suggestion and patient compliance produced confirmation, and by the early 1990s the output included not only incest accusations but recovered “memories” of multi-generational satanic cults, ritual murder, and cannibalism — claims that, despite years of FBI scrutiny, never yielded a body or a corroborated crime scene.
The reversal came from the laboratory and the courtroom, not the clinic. Cognitive psychologist Elizabeth Loftus, who had spent two decades showing memory to be reconstructive and suggestible, published “The Reality of Repressed Memories” in American Psychologist in 1993, and with Jacqueline Pickrell ran the 1995 “lost in the mall” study, in which roughly a quarter of adult subjects came to “remember” a childhood event — being lost in a shopping mall — that their families confirmed had never happened. If a benign false memory could be implanted in a research session, an abuse memory could be implanted over months of suggestive therapy. The American Medical Association declared recovered memories unreliable in 1994; courts increasingly ruled the method not generally accepted; and the paradigm collapsed.
“Overturned” files this as TH-012 because the revoked object is not a drug or a device but a theory of mind — a confident clinical model of how memory works — disconfirmed by direct experiment and rejected on the record by the legal system that had briefly enshrined it.
