Argumentum ad nauseam
Argumentum ad nauseam or
argument from repetition is the false proof of a statement by (prolonged) repetition, possibly by different people. This
logical fallacy is commonly used as a form of
rhetoric by
politicians. In its extreme form, it can also be a form of
brainwashing. This logical fallacy tends to be convincing to people because, as
Joseph Goebbels discovered, if something is repeated as true often enough, people will eventually come to accept it.
