9. Project MKOFTEN: Occult Investigations

Project MKOFTEN was a covert U.S. Department of Defense program developed in conjunction with the CIA in the late 1960s. A partner of MKULTRA, its goal was to “test the behavioral and toxicological effects of certain drugs on animals and humans.” Testing occurred on animals, prisoners at Holmesburg Prison in Philadelphia, and military personnel at Edgewood Arsenal. Beyond drug testing, MKOFTEN delved into the realm of the supernatural, exploring the potential of occult practices for intelligence purposes. The program investigated the effects of black magic, voodoo, demonology, and other esoteric practices on human behavior. The CIA consulted with various mystics, including fortune-tellers, palm readers, clairvoyants, and practitioners of witchcraft, to assess whether such practices could be harnessed for espionage or military applications. The results of these occult investigations remain largely mysterious, with limited information available due to the classified nature of the program. While some details have emerged through declassified documents and investigative reports, the full extent and outcomes of MKOFTEN’s activities continue to be subjects of speculation and intrigue (innate-awareness.com).
