In the early 1950s, Jackins became acquainted with L. Ron Hubbard's theory of Dianetics. In 1952 Jackins formed Personal Counselors Inc. to "engage in, conduct and teach the art and science of Dianetics." While practicing Dianetics, he developed the concepts of "re-evaluation" and "discharge" and came to believe that they could be encouraged by the "exchange of aware attention" in the "co-counseling process". At this time, Jackins used some of the terminology of Dianetics, such as "clearing up patterns", "rationality", "present time" and "passing distress by contagion". Psychiatrist Richard M. Childs claimed that Jackins' book "The Human Side of Human Beings" (1965) plagiarized Hubbard's "Dianetics" (1950), saying that Jackins "paraphrased Hubbard's terms by recasting them in his own jargon. Hubbard's 'Engrams' became Jackins' 'distress patterns', 'release' became 'discharge', and 'to become clear' became RC's 'to re-emerge'." In 1957, Hubbard's Scientology organisation claimed that Jackins was describing himself as a "Dianetics Auditor".
