Project Chatter: The Beginning of CIA’s Mind Control Experimentation

Project Chatter, a highly classified operation carried out by the United States Navy during the Cold War era, delved into the realms of mind control and chemical interrogation. Launched in the fall of 1947, this covert program aimed to develop new methods for extracting information and manipulating human behaviour through the use of drugs, including LSD and other mind-altering substances.

Led by Charles Savage of the Naval Medical Research Institute in Bethesda, Maryland, the program conducted laboratory experiments on animals and unsuspecting humans from 1947 to 1953. Its primary objectives were to identify effective agents for interrogation, explore treatments for depression, and study substances like anabases, scopolamine, mescaline, and notably, Lysergic acid diethylamide (LSD-25), the first U.S. government project involving LSD on human subjects. In 1953, the Navy concluded the project, merging its experiments into Project MKULTRA.

Origins and Motivations

Project Chatter emerged against the backdrop of intense geopolitical tensions during the Cold War. The CIA, concerned about potential Soviet advances in mind control techniques, sought to gain a competitive edge by exploring similar methods. The project drew inspiration from earlier Nazi experiments, such as those conducted at Dachau concentration camp, as well as the Japanese Unit 731’s research into chemical interrogation during World War II.

Nazi experiments, notably those conducted at Dachau concentration camp, represent a dark chapter in the history of medical experimentation. Under the guise of scientific research, Nazi doctors subjected prisoners to horrific experiments involving forced sterilization, exposure to extreme temperatures, infectious diseases, and other forms of torture. These experiments aimed to advance knowledge in fields like hypothermia, sterilization, and infectious diseases, but they inflicted immense suffering and resulted in countless deaths.

During World War II, Japanese Unit 731 conducted research into chemical interrogation methods, frostbite testing, vivisection of conscious prisoners, etc. This covert operation involved unethical and inhumane experimentation on prisoners of war and civilians. Unit 731 explored the effects of various chemical substances on subjects, seeking to develop interrogation techniques that would induce pain, fear, and disorientation. The research conducted by Unit 731 remains a grim reminder of the atrocities committed in the name of scientific advancement during wartime.

Human Experiments

Interrogation Techniques

Project Chatter aimed to develop effective methods for interrogation and extracting information from individuals unwilling to cooperate. In pursuit of this goal, subjects were administered various mind-altering substances to lower inhibitions, enhance suggestibility, and induce confusion.

Drug Trials

The experimentation involved administering drugs, such as LSD, mescaline, scopolamine, and other hallucinogens, to human subjects without their knowledge or consent. Researchers sought to observe the effects of these substances on behaviour, memory, and perception. It is important to note that the majority of subjects were unwitting participants, including military personnel, government employees, and even civilians.

Behaviour Modification

Beyond gathering intelligence, Project Chatter sought to explore the potential for controlling and manipulating human behaviour. Researchers experimented with combinations of drugs to influence emotions, increase suggestibility, and create amnesia. Hypnosis and other psychological techniques were also employed to facilitate behaviour modification.

Animal Experiments

Animal Models

In addition to human subjects, Project Chatter extensively employed animals, particularly primates, as test subjects. Animals were chosen due to their physiological similarities to humans, allowing researchers to draw correlations between drug effects in animals and potential human applications.

Behavioural Observations

Primates, such as chimpanzees, were subjected to controlled drug administration to monitor changes in behaviour, cognition, and memory. These observations aimed to shed light on the potential effects and risks associated with mind-altering substances.

Physiological Studies

The experiments extended to analysing the physiological impacts of drugs on animals. Researchers conducted autopsies and post-mortem examinations to examine the effects of substances on the brain, nervous system, and other vital organs. These findings were used to guide the human experimentation aspect of the project.

Drugs Utilized

LSD (Lysergic Acid Diethylamide)

The psychedelic drug LSD played a central role in Project Chatter. Administered to both human and animal subjects, LSD was intended to induce altered states of consciousness, disorientation, and hallucinations. Researchers aimed to exploit these effects for interrogation purposes and to explore the potential for mind control.


Derived from the peyote cactus, mescaline was used as an alternative to LSD. Its hallucinogenic properties were investigated for their potential to induce altered mental states and facilitate manipulation of human behaviour.


Known for its amnesic and sedative effects, scopolamine was administered to subjects to study its impact on memory recall and suggestibility. Researchers sought to determine if it could be used to create a state of pliability in subjects, enhancing the effectiveness of interrogation techniques.

Drugs Utilized

Covert Administration

Project Chatter experiments often involved administering drugs to individuals without their knowledge or consent. Substances were covertly introduced into food, beverages, cigarettes, or through aerosol sprays, allowing researchers to observe the effects in a real-world scenario.

Controlled Environments

Some experiments required a controlled environment to closely monitor subjects. Isolation chambers, specially designed rooms, or safe houses were used to maintain a controlled setting and observe subjects’ reactions in isolation.

Behavioural Monitoring

Extensive records were kept during experiments, documenting subjects’ physiological and psychological responses to the administered drugs. These observations were crucial in understanding the effects of mind-altering substances on behaviour, cognition, and memory.


Project Chatter, along with subsequent CIA mind control programs like MKUltra, has faced significant criticism due to ethical violations and the potential harm inflicted on unwitting participants. The lack of informed consent, potential long-term psychological damage, and the use of covert administration methods are subjects of particular concern.

Project Chatter represents a dark chapter in the history of intelligence agency experimentation. The CIA’s pursuit of mind control techniques, through the administration of drugs to human and animal subjects, reveals the lengths to which they were willing to go in their quest for strategic advantage during the Cold War. The ramifications of these experiments are still felt today, raising profound questions about the ethics of covert government research and the protection of human rights in the pursuit of national security.
