From Wikipedia: In his second year at Harvard, Kaczynski participated in a study described by author Alston Chase as a "purposely brutalizing psychological experiment" led by Harvard psychologist Henry Murray. Subjects were told they would debate personal philosophy with a fellow student and were asked to write essays detailing their personal beliefs and aspirations. The essays were turned over to an anonymous individual who would confront and belittle the subject in what Murray himself called "vehement, sweeping, and personally abusive" attacks, using the content of the essays as ammunition.[23] Electrodes monitored the subject's physiological reactions. These encounters were filmed, and subjects' expressions of anger and rage were later played back to them repeatedly.[24] The experiment lasted three years, with someone verbally abusing and humiliating Kaczynski each week.[25][26] Kaczynski spent 200 hours as part of the study.[27]

Kaczynski's lawyers later attributed his hostility towards mind control techniques to his participation in Murray's study.[24] Some sources have suggested that Murray's experiments were part of Project MKUltra, the Central Intelligence Agency's research into mind control.[28][29] Chase[30][24] and others[31][32] 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. He also said he was "quite confident that my experiences with Professor Murray had no significant effect on the course of my life"
