Dianetics is a set of pseudoscientific ideas and practices regarding the relationship between the human mind and body created by science fiction writer and Scientology founder L. Ron Hubbard. Dianetics is practiced by followers of Scientology and the Nation of Islam (as of 2010).Dianetics was originally conceived as a branch of psychiatry, which Hubbard would come to despise when various psychoanalysts dismissed it as unscientific. Though it is presented as a form of psychological treatment, Dianetics and its core concepts have been rejected by psychologists and other scientists from the outset and are not supported by credible evidence.: 106–107  Source: Wikipedia (en)
