Reference excerpt

The Terre Haute prison experiments were conducted by Dr. John C. Cutler in 1943 and 1944 under Dr. John F. Mahoney, the head of the Venereal Disease Research Laboratory of the US Public Health Service, to determine the effectiveness of treatments for sexually transmitted diseases. The experiment focused on creating prophylaxis treatments for gonorrhea. The test subjects were prisoners at the U.S. Penitentiary in Terre Haute, Indiana. They were given disclosures and consented to the experiments. A total of 241 prisoners participated in the study and received $100, a certificate of merit, and a letter of commendation to the parole board at the end of the study. The researchers deposited various strains and concentrations of gonorrhea into the penises of the test subjects. After several months, Mahoney noted that the method of inducing gonorrhea in humans was unreliable and could not provide meaningful tests of prophylactic agents. The Terre Haute experiments laid the foundation for and bore many similarities to the Guatemala syphilis experiments, including many of the same researchers, goals, and methods.

Experiment overview

Historical context The Terre Haute prison experiments began during World War II to create a prophylaxis treatment for gonorrhea. Venereal diseases had been an issue previously during World War I and had cost the army seven million days of active duty. Gonorrhea did not have a medical treatment at this time and was difficult to study because only humans can contract it. This initiated extensive research on how to prevent and treat gonorrhea to reduce infection rates in the armed forces. During an NRC meeting about venereal diseases, two researchers from New York proposed the idea of using volunteer prison inmates as test subjects. They argued that inmates were the ideal test subject because they could be well monitored and prohibited from sexual activity. The NRC agreed with their argument but worried about the public reaction to this experiment. Gonorrhea was becoming a growing problem amongst all areas of the population and the only way to study it was through human experimentation. The NRC eventually endorsed this study because they thought the benefits of creating prophylaxis treatments for gonorrhea outweighed the risks of a negative public reaction.

Study details The study was conducted in Terre Haute, Indiana at the federal penitentiary in September 1943. There were three locations considered for this experiment, but Terre Haute was chosen due to their superior medical facility. There were 241 test subjects chosen from the prison. The requirements to participate in the experiment were that you be at least 21 years old and fully understood the risks involved. The prisoners signed waivers and were told they would receive $100 and a letter of recommendation for parole after completing the experiment. The researcher's initial task was to find a consistent method of inoculation. The researchers had taken samples of gonorrhea from recently arrested sex workers. They gathered many different strains of gonorrhea and experimented with inoculating the test subjects with different concentrations. The method of inoculation used was to apply a sample of gonorrhea to the end of the test subjects' penises. However, after five months of using this method for inoculation, researchers became concerned with the inconsistency. The leader of the experiment, Dr. Mahoney, reported his unsuccessful attempts at inoculation to the National Research Council. The NRC encouraged the continuation of the experiment. Dr. Cutler, who had been working alongside Dr. Mahoney, tried additional attempts at inoculation but was unsuccessful. After many different failed attempts at inoculation, Dr. Mahoney decided to end the experiment. Dr. Mahoney realized that without a consistent way to inoculate test subjects, they could not effectively test prophylaxis treatments. The Terre Haute Prison experiments were conducted for only ten months and officially ended in July 1944.

Study clinicians This study was conducted by Dr. John Cutler, Dr. John Mahoney, Dr. Joseph Earle Moore, and Dr. Cassius J. Van Slyke.

Aftermath

Continued research After the Terre Haute Prison Experiments, Dr. Mahoney and Dr. Cutler continued their experiments on venereal diseases in the Guatemala Syphilis experiments.

Worked examples

Example 1 — a first encounter with Terre Haute prison experiments

Start with the simplest possible case. Write down what Terre Haute prison experiments claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Terre Haute prison experiments before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Terre Haute prison experiments ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Terre Haute prison experiments

In research: Terre Haute prison experiments appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Terre Haute prison experiments in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Terre Haute prison experiments is common in secondary-school and first-year university syllabi. It links to neighbouring topics Clinical trials, Human subject research in the United States, Medical experimentation on prisoners, so understanding it makes those chapters shorter.
In everyday life: Look for Terre Haute prison experiments outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
