MK-ULTRA LSD experiments were discovered during an internal survey of the CIA’s technical services division headed by Sid Gottlieb. In his report, JS Earman, the IG stated:

The concepts involved in manipulating human behavior are found by many people both within and outside the Agency to be distasteful and unethical. . . The experience of TSD to date indicates that both the research and the employment of the materials are expensive and often unpredictable in results. . . The principal conclusions of the inspection are that the structure and operational controls over this activity need strengthening; improvements are needed in the administration of research projects; and some of the testing of substances under simulated operational conditions was judged to involve excessive risk to the Agency.

Following the I.G. Report, most sensitive sub-parts of MK-ULTRA were transferred to MK-SEARCH.
