Thought-terminating cliché

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, often passing as folk wisdom, intended to end an argument and quell cognitive dissonance. Its function is to stop an argument from proceeding further, ending the debate with a cliché rather than a point. Some such clichés are not inherently terminating; they only become so when used to intentionally dismiss dissent or justify fallacious logic.

The term was popularized by Robert Jay Lifton in his 1961 book Thought Reform and the Psychology of Totalism, who referred to the use of the cliché, along with "loading the language", as "the language of non-thought".
