Jon’s Work

Jon Atack left school at 17 to play drums in various rock bands. He joined the Scientology cult aged 19. Although he was never a live-in member, he took many courses and 25 of the available levels of the ‘Bridge’ – to Operating Thetan Section V.


Jon left the cult in 1983, appalled by its aggressive behaviour towards members. He refused to ‘disconnect’ (or shun) a close friend and was shocked to discover that eleven senior members of the cult – including the leader’s wife – had been sentenced to prison terms for kidnapping, breaking and entering, theft, burglary and false imprisonment, based on their own confessions. His groundbreaking research began a lifetime of work devoted to helping those harmed by the cult’s hypnotic practices.

For more than 20 years, Jon has met over 600 former members and helped many to recover the money that had been extracted from them by Scientology’s hard selling techniques. He was active on over 150 court cases and was consulted by many government organizations. Now credited as one of the world’s leading experts on high-control authoritarian groups, Jon continues to teach, to share his insights through his YouTube channel and to try and get some time on the drums.

In addition to his own books, Jon’s research was the basis for Barefaced Messiah, Russel Millers acclaimed biography of L. Ron Hubbard.

He continues to collaborate with his many friends, including Steven Hassan and Yuval Laor.

Jon and Steven contributed to Lone-Actor Terrorism, published by Oxford University Press in 2022.
