Project ARTICHOKE also known as Operation ARTICHOKE was run by the CIA's Office of Scientific Intelligence.
The project went deeper into interrogation methods studied in the CIA's Project BLUEBIRD. ARTICHOKE offensive mind control techniques experiments attempted to induce amnesia and highly suggestive states in its subjects. ARTICHOKE focused on the use of hypnosis, forced morphine addiction, forced morphine addiction withdrawal,along with other drugs, chemicals, and techniques.
The main focus of the program was summarized in a January 1952 CIA memo,"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?"
One program experiment attempted to see if it was possible to produce a"Manchurian Candidate."
In Richard Condon’s 1959 novel "The Manchurian Candidate" an American soldier, who has been placed into a hypnotic state by Communist forces, returns home to assassinate on command.
Five years earlier the CIA considered the possibility. A January 1954 CIA report
asks the question, “Can an individual of [redacted] descent be made to perform an act of attempted
assassination involuntarily under the influence of ARTICHOKE?”
