Project MKUltra
Kaczynski's lawyers later attributed his hostility towards mind control techniques to his participation in Murray's study. Some sources have suggested that Murray's experiments were part of Project MKUltra, the Central Intelligence Agency's research into mind control. Chase and others have also suggested that this experience may have motivated Kaczynski's criminal activities. Kaczynski stated he resented Murray and his co-workers, primarily because of the invasion of his privacy he perceived as a result of their experiments. Nevertheless, he said he was "quite confident that my experiences with Professor Murray had no significant effect on the course of my life".
