Understanding the Tuskegee Experiment
June 2023
The Tuskegee Experiment, also known as the Tuskegee Syphilis Experiment, was a deeply racist and unethical clinical research study that took place between 1932 and 1972 in Tuskegee, Alabama, under the auspices of the United States Public Health Service (USPHS). In medical circles, it is referred to as the USPHS Syphilis Study at Tuskegee. In essence, the study investigated the natural progression of untreated syphilis in African American men.
Despite its name, the study involved neither experimentation nor treatment. Instead, it was an observational study that aimed to document the effects of untreated syphilis on the human body. The study was highly controversial and is now widely regarded as one of the most egregious examples of unethical medical research in modern history.
The Study Design and Realities
The so-called Tuskegee Experiment involved a group of 399 African American men diagnosed with syphilis as well as 201 uninfected men, who served as the control group. The study participants were told that they were being treated for “bad blood,” a term that was commonly used in the South to describe a variety of illnesses, including syphilis, anemia, and general fatigue. However, the men were never informed either that they had syphilis or that they were part of a clinical study.
The study was designed to be observational in nature. This meant that the researchers would not provide any treatment to the participants despite the fact that penicillin, the first effective treatment for syphilis, was already being widely used in the 1940s. The study participants were periodically examined, had blood samples taken, and were given sham or placebo “treatments,” but were never actually treated for syphilis. In fact, involved physicians actually contacted other doctors in the area to prevent them from treating the study’s participants.
Instead, in exchange for participating in what they believed was a hematological study (a study of blood and blood disorders), the men were offered free medical exams, free meals on examination days, transportation to and from the clinics, and chillingly, burial stipends for the loved ones who survived them.
The study was initially intended to last for only six months, but it was extended several times, eventually lasting for 40 years. During this period, the study participants suffered grievously from the debilitating effects of untreated syphilis. These included blindness, deafness, neurological damage, other severe health problems, and death.
Human Rights Violations
The Tuskegee Experiment was clearly a profound violation of medical ethics and human rights on several levels: the deception of the participants, the withholding of treatment, and the perpetuation of physical and emotional suffering on the part of the participants and their families. The study also racially targeted African American men, who were already acutely discriminated against at the time, because they were viewed as relatively powerless and dispensable subjects.
The USPHS syphilis study also violated the principles of the Nuremberg Code, a set of ethical guidelines developed in response to the unconscionable medical experiments conducted by Nazi doctors during World War II. In effect, the Nuremberg Code stipulates that:
Research participants must give informed consent
Research must be conducted in a way that minimizes harm
Research must be based on scientific validity
The Tuskegee Experiment clearly violated all of these principles.
The Lasting Consequences of the Study
The Tuskegee Experiment was eventually exposed by a whistleblower, Peter Buxtun, a former Public Health Service employee who had learned about the study in 1966. Buxtun brought the study to the attention of the media, and the story eventually gained national attention.
As a result of the publicity generated by the Tuskegee Experiment, the USPHS was forced to end the study in 1972, and a class-action lawsuit was filed on behalf of the study participants and their families. In 1974, the lawsuit was settled for $10 million, and the USPHS issued a formal apology to the study participants and their families.
The Tuskegee Experiment had far-reaching effects on medical research and ethics. In a constructive sense, it led to the development of a number of regulations and guidelines that are now in place to protect research participants. This includes the Belmont Report, which outlines the ethical principles for the conduct of research involving human subjects. The syphilis study also led to increased awareness of the importance of informed consent and the need for researchers to be transparent and ethical in their studies.
However, the Tuskegee Experiment also had long-lasting damaging impacts on African American trust in US medical systems, as it revealed the deep racism and discrimination that existed in healthcare (and still exists today). It caused many Black Americans to avoid participating in medical research and even seeking medical care at all, which has been detrimental to public health in communities of color.
This was particularly evident during the COVID-19 pandemic and the related reluctance in communities of color to get vaccinated. Many African Americans who did want to be innoculated faced barriers to vaccine access due to the lasting socioeconomic effects of systemic racism in other forms.
The legacy of the USPHS Syphilis Study continues to impact the medical profession and research today. The study has become a symbol of unethical medical research and a cautionary tale. It has also led to increased awareness of the importance of diversity in clinical research and the need to address health disparities that disproportionately affect communities of color.
