Milieu control

Milieu control is a term popularized by psychiatrist Robert Jay Lifton to describe tactics that control environment and human communication through the use of social pressure and group language; such tactics may include dogma, protocols, innuendo, slang, and pronunciation, which enables group members to identify other members, or to promote cognitive changes in individuals. Lifton originally used "milieu control" to describe brainwashing and mind control, but the term has since been applied to other contexts.
