The consent form a patient signs before entering a clinical trial, the institutional review board that must approve the study, the principle that a person's participation must be voluntary and informed — none of these existed for most of the twentieth century. They were built, painfully, in response to a series of abuses in which physicians and researchers, often with the sanction of the state, treated vulnerable people as material rather than patients. Several of the most consequential of these abuses were carried out on people with mental illness, intellectual disability, or the poor and institutionalized. This chapter traces four of them — eugenic sterilization and Buck v. Bell, the Tuskegee syphilis study, the CIA's MKUltra program, and the Willowbrook hepatitis studies — and shows how each fed the framework of modern research ethics: the Nuremberg Code, the Declaration of Helsinki, the Belmont Report, the Common Rule, and the IRB system that governs research today.

Why psychiatry owns this history: People with psychiatric and developmental disabilities were disproportionately the victims of research abuse, because they were institutionalized, stigmatized as "unfit" or "incurable," and often legally unable to refuse. The safeguards that resulted — capacity-based consent, protections for vulnerable populations, independent review — are therefore central to psychiatric practice and research, not peripheral to it. This chapter is difficult reading by design.

Eugenics and Buck v. Bell: the state as sterilizer

In the early twentieth century, the pseudoscience of eugenics — the belief that society could be improved by preventing the "unfit" from reproducing — captured mainstream medicine, science, and law. "Feeblemindedness," insanity, epilepsy, criminality, and poverty were treated as heritable defects. More than thirty U.S. states passed compulsory-sterilization laws targeting people in psychiatric hospitals and institutions for the intellectually disabled.

Buck v. Bell

274 U.S. 200 (1927)

The facts: Carrie Buck, a young woman committed to a Virginia institution, was selected as a test case for the state's sterilization law. She was described as "feebleminded," as was her mother and her infant daughter — a supposed three-generation pedigree of defect. In reality the evidence was thin to fabricated: Carrie had been institutionalized after a pregnancy that resulted from rape by a relative of her foster family, and her daughter was, by later accounts, a normal child.

The holding: The U.S. Supreme Court, 8–1, upheld compulsory sterilization. Justice Oliver Wendell Holmes Jr. wrote the notorious opinion, concluding: "Three generations of imbeciles are enough."

The consequences: Buck v. Bell gave constitutional cover to the forced sterilization of tens of thousands of Americans, most of them poor, institutionalized, disabled, or nonwhite. The American eugenics movement and its laws were later studied and admired by Nazi Germany, whose sterilization and "euthanasia" programs (including the murder of psychiatric patients) drew explicitly on the U.S. example. Buck v. Bell has been widely repudiated but has never been formally overruled.

The eugenic era is the origin of a hard lesson: a medical and scientific consensus, backed by the highest court, can be catastrophically wrong — and the people least able to resist are the ones it harms.

The Nuremberg Code: consent as a first principle

The Nazi doctors' experiments — including lethal experiments on concentration-camp prisoners — were prosecuted at the Nuremberg "Doctors' Trial" (1946–47). The judgment produced the Nuremberg Code (1947), whose very first principle is that "the voluntary consent of the human subject is absolutely essential." The Code established, for the first time as an international standard, that research on human beings requires informed, voluntary consent; that risks must be justified by benefits; and that subjects must be free to withdraw. The World Medical Association's Declaration of Helsinki (1964, since revised many times) extended these principles into a practical framework for clinical research. Yet — crucially — these codes did not immediately change practice in the United States, as the next two cases show.

Tuskegee: forty years of deliberate non-treatment

The U.S. Public Health Service Study of Untreated Syphilis (Tuskegee, 1932–1972)

Beginning in 1932, the U.S. Public Health Service enrolled about 600 poor Black men in Macon County, Alabama — roughly 400 with latent syphilis and 200 controls — in a study of the natural course of untreated syphilis. The men were never told they had syphilis; they were told they were being treated for "bad blood" and were given placebos, sham procedures, and free meals and burial insurance to keep them enrolled.

The betrayal deepened over time. When penicillin became the standard, effective cure for syphilis in the 1940s, it was deliberately withheld from the men so the study of untreated disease could continue. Researchers even worked to prevent the subjects from being treated elsewhere. The study ran for forty years, ending only in 1972 after a whistleblower, Peter Buxtun, brought it to the press. By then many men had died of syphilis, and wives and children had been infected.

Tuskegee is the most infamous research-ethics violation in American history. It was not a secret rogue operation but a government study, published in the medical literature over decades. Its exposure produced a national reckoning, a federal settlement, and — in 1997 — a formal presidential apology. It is also a principal source of the enduring, well-founded medical mistrust in Black American communities.

MKUltra: experimentation without knowledge or consent

The CIA's MKUltra program (roughly 1953–1973)

MKUltra was a covert Central Intelligence Agency program to study mind control, interrogation, and behavior modification during the Cold War. It funded experiments — often through universities, hospitals, and prisons using front organizations — that administered LSD and other drugs, hypnosis, sensory deprivation, and other techniques to people who frequently had no idea they were subjects. Some were psychiatric patients; some were prisoners; some were ordinary citizens dosed without any consent whatsoever. In the notorious "Operation Midnight Climax," the CIA dosed unwitting men with LSD in safe houses and observed them.

Psychiatry was directly implicated. The program funded work by prominent researchers, most infamously the "depatterning" and "psychic driving" experiments of psychiatrist Ewen Cameron in Montreal, in which patients who had come for ordinary psychiatric help were subjected to massive electroconvulsive therapy, drug-induced prolonged sleep, and endlessly repeated taped messages — leaving many permanently harmed.

MKUltra was exposed in the mid-1970s through investigative journalism and the congressional Church Committee hearings; most of its records had been deliberately destroyed in 1973. It stands as the starkest case of research conducted with no consent, no oversight, and no accountability, and it shattered any assumption that professional and governmental institutions could be trusted to police themselves.

Willowbrook: consent under coercion

The Willowbrook hepatitis studies (1955–1970s)

Willowbrook State School on Staten Island was a grossly overcrowded institution for children with intellectual disabilities, where hepatitis was endemic. Researchers led by Saul Krugman conducted studies in which children were deliberately infected with hepatitis (by feeding them extracts from infected stool, and later injections) to study the disease's course and test gamma-globulin protection. The scientific work did advance understanding of hepatitis A and B.

The ethical violation lay in the coercion. Parents did give a form of consent — but many were told that the only way to get their child admitted to the chronically overcrowded institution was through the special research unit. Consent extracted from desperate parents as a condition of access to care is not free consent. The victims were institutionalized, disabled children — among the most vulnerable subjects imaginable.

The framework these abuses built

Together, Tuskegee, MKUltra, and Willowbrook — revealed in close succession in the early-to-mid 1970s — forced the United States to build the modern system of research protection it had failed to adopt from the Nuremberg Code alone.

  • 1974National Research Act. Passed largely in response to Tuskegee, it required institutional review boards (IRBs) for federally funded research and created the National Commission for the Protection of Human Subjects.
  • 1979The Belmont Report. The Commission's landmark statement set out three core principles: respect for persons (autonomy and informed consent, with special protection for those with diminished autonomy), beneficence (maximize benefit, minimize harm), and justice (fair distribution of the burdens and benefits of research — a direct answer to Tuskegee's exploitation of the poor and Black).
  • 1981 onwardThe Common Rule. Federal regulations (45 CFR 46) codified IRB review, informed-consent requirements, and — in dedicated subparts — extra protections for vulnerable populations: prisoners, children, and pregnant women. Research involving people with impaired decision-making capacity draws heightened scrutiny.
  • OngoingCapacity-based consent. Modern practice requires that consent be not only voluntary and informed but given by someone with the capacity to give it — connecting research ethics directly to the clinical capacity evaluation and to surrogate-decision frameworks when capacity is absent.

What this history teaches

The through-line of these abuses is not individual villainy but a structural failure: vulnerable people, defined as less than fully human or less than fully autonomous, were used for ends that were not their own, with no independent check on the people using them. Each pillar of modern research ethics maps onto a specific failure — informed consent answers MKUltra's secrecy, protection of vulnerable populations answers Willowbrook's coercion, justice answers Tuskegee's exploitation, and the very idea of limits on what the state may do to the "unfit" answers Buck v. Bell. The safeguards can feel bureaucratic from inside a modern IRB submission. This history is the reason they exist, and the reason they should never be treated as a formality — especially by a specialty whose patients are so often the people these protections were built for.
