The propagandist technique of using the tireless repetition of an idea. An idea, especially a simple slogan, that is repeated enough times, may begin to be taken as the truth. This approach works best when media sources are limited and controlled by the propagator.
"Ad nauseam" arguments are logical fallacies relying on the repetition of a single argument to the exclusion of all else. This tactic employs intentional obfuscation, in which other logic and rationality is intentionally ignored in favour of preconceived (and ultimately subjective) modes of reasoning and rationality.
