Authorship: Despite its elaborate framing as a Soviet document, substantial evidence suggests that L. Ron Hubbard himself authored the Brain-Washing Manual. His estranged son, L. Ron Hubbard Jr., asserted, “Dad wrote every word of it. Barbara, Bryan, and my wife typed the manuscript from his dictation.” This claim was later corroborated by a former editor who worked closely with Hubbard.
Characteristic Writing Style: Researchers have noted that the document is "filled with what is clearly evidence of Hubbard's own writing style". It includes terms and concepts unique to Hubbard's work, such as "thinkingness" and "pain-drug-hypnosis".
