Claim: Thought-terminating Clichés (popularized by psychiatrist Robert Jay Litton in his 1961 book) are words or phrases that discourage critical thought–for example: "Stop thinking so much."
Evidence: The term was popularized by Robert Jay Lifton in his 1961 book Thought Reform and the Psychology of Totalism, who called the use of the cliché, along with "loading the language", as "The language of Non-thought". "Stop thinking so much." – A literal request to stop any debate. A thought-terminating cliché (also known as a semantic stop-sign, a thought-stopper, bumper sticker logic, or cliché thinking) is a form of loaded language, commonly used to quell cognitive dissonance.
