John Mack

Harvard psychiatrist who studied people reporting alien abduction experiences and whose clinical conduct in this research was subject to a confidential Harvard Medical School review.

Harvard University · Psychiatrist, researcher

John Mack was a Harvard psychiatrist and researcher1 who studied people who reported experiences with anomalous phenomena.1 According to David Charles Grusch, Mack concluded that something real was occurring in the experiences reported to him, and that it was not a psychosomatic or mental health condition.2 According to American Cosmic, Mack claimed that the experiencers he studied were psychologically healthy and that the experiences they described were common,3 and he came to see alien abduction experiences as a significant cultural development demanding serious scholarly attention.4 In the course of his research he approached the philosopher of science Thomas Kuhn, who argued that scientific revolutions came about through attention to anomalies;5 according to Diana Walsh Pasulka, Kuhn advised Mack to focus on raw data and to persist in collecting it even when it did not fit conventional frameworks of knowledge.6

Mack’s work is grouped alongside that of Budd Hopkins as providing circumstantial evidence for alien abduction, including landing-site traces, biopsy scars, alleged implants, and testimony from abducted individuals.7 By 1991, after a wave of publications on alien abduction from Mack, Hopkins and others, the practice of hypnotic regression used in this research came under scrutiny.8 In 1994, following the revelation that the Dean of Harvard Medical School had appointed a committee of peers to confidentially review Mack’s clinical care and investigation of alleged alien abduction experiencers, Daniel Sheehan defended him;9 this 1994 Harvard review of John E. Mack put his tenure as a Harvard University professor under threat.10 Sheehan’s support for Mack during the review was funded by the billionaire Laurance Rockefeller.11 After a 14-month investigation, Harvard declared Mack’s freedom to study what he wished and to state his opinions without impediment.12 Tom DeLonge said that Mack almost lost his job because he started writing books about UFOs and people getting abducted.13 Ralph Blumenthal later worked on a biography of Mack, describing him as a Harvard psychiatrist who treated and extensively interviewed people claiming to have been abducted by or to have encountered aliens.14

Mack’s 1994 book Abduction: Human Encounters with Aliens reached a wide readership; James Master picked it up believing it to be science fiction and found it read like his own biography, which helped him frame his own experiences as UFO-related.15 Edward Carlos, another experiencer, felt that while Mack was attentive to his feelings, Mack never had a grasp of the real phenomenon.16

Mack conducted hypnotic regression sessions with Peter Khoury as part of the Peter Khoury John Mack hypnotic regression sessions. During a 1996 visit to Australia, New South Wales, Sydney, Mack regressed Khoury under hypnosis in an attempt to clarify Khoury’s 1988 experience beyond a moment of blankness that had followed the sensation of a needle being inserted in his head, in what became John Mack’s 1996 hypnotic regression of Peter Khoury.17 During the sessions Mack observed a difference in Khoury’s demeanour when recalling three beings that looked scary or evil-looking, whom Khoury perceived as robust like military figures, compared with others he perceived as scientists.18 A female psychiatrist was also present observing one of the sessions.19 Khoury was sweating heavily while recalling the encounter, then abruptly stopped sweating and became calm the moment he described looking into the eyes of a gold-coloured being;20 according to Khoury, Mack and the observing psychiatrist agreed that this sudden physiological shift could not have been faked.21 Khoury also underwent hypnotic regression with Frank Wilkes, one of the first hypnotherapists in the Peter Khoury alien abduction support group.22 Khoury recounted that Mack later told him, after a workshop while driving home, that he admired and respected how Khoury dealt with his own experience while also helping others deal with theirs;23 Khoury believes Mack was drawn to him because, unlike other witnesses, he did not push his own story onto Mack.24

Mack’s research also took him to Zimbabwe, where he investigated the Ariel School incident, and brought him into contact with Credo Mutwa, the Zulu sangoma whose alien-themed paintings, connected to Mantindane (Zulu alien-being lore), predated the recording of his stories by Mack and Stephen Larsen in Credo Mutwa’s 1983 alien paintings.13 Mack reported a rapid healing of a hand injury that he said had followed a 1976 encounter between the Mantindane and Mutwa.25 Mack’s professional difficulties were later compared to those of Roger Leir, whose licence to practise medicine was likewise challenged and who faced a nuisance lawsuit that harmed his practice.26
