Project ARTICHOKE was a CIA project that researched interrogation methods and arose from project BLUEBIRD in 1951. The project studied hypnosis, among other methods, to produce amnesia in subjects.
Project ARTICHOKE was an offensive program of mind control that gathered together the intelligence divisions of the Army, Navy, Air Force, and FBI. I believe the ILP (Indian Lake Project) was a part of Project ARTICHOKE.
The scope of the project was outlined in a memo dated January 1952 that stated, "Can we get control of an individual to the point where he will do our bidding against his will and even against fundamental laws of nature, such as self preservation?"
Project ARTICHOKE was renamed project MKULTRA in 1953 (see links for more information) and was first brought to wide public attention by the U.S. Congress – in the form of the Church Committee and a presidential commission – known as the Rockefeller Commission.
Central Intelligence Agency documents suggest that the agency considered and explored uses of radiation for the purpose of mind control as part of MKULTRA. Other early efforts focused on LSD, which appears to have formed the majority of research as time went on. Experiments included dosing CIA employees, military personnel, other government agents, prostitutes, mental patients, and members of the general public with LSD to study their reactions, usually without the subject's knowledge. When Project ARTICHOKE became MKULTRA, the ILP’s roll was reduced, and then eliminated. There are many declassified documents from the congressional hearings (see link). None however, mentions very young children (12 or younger) being used in MKULTRA experiments. I think by then, the ILP was buried – both literally and figuratively.
