Ad nauseum repetition is the stuff urban legends are made of. Hitler’s Propaganda Minister, Joseph Goebbels, said that if only you repeat something often enough, people will come to believe it. None of these response addresses the actual pros and cons of the proposal to privatize Social Security.Ī preemptive ad hominem attack, launched before the discussion fairly begins, is called “Poisoning the Well” (below). Similarly, you would be guilty of an ad hominem attack if you exclaimed, “How can you claim to be a born-again Christian?” (pointing out an inconsistency of position) or “Of course you would say that-you’re a Libertarian!” (pointing out personal bias). For example, in a discussion of the pros and cons of privatizing Social Security, it would be an ad hominem attack simply to declare your opponent a parasite feeding on the lifeblood of the working class.

At least some propaganda techniques are used occasionally by non-profit organizations, advertisers, churches, news organizations, governments, and instructors.įor good or ill, makers of propaganda typically select facts most appropriate to their purpose and omit facts that do not help them achieve that purpose.
While the word itself carries rather a negative connotation (implying intent to mislead or deceive) the techniques can be used in good causes as well-a Cancer Society fundraiser, for example. Propaganda intends to persuade without offering a logical reason to adopt a particular view or take a particular action. It is aimed at forming opinions rather than increasing knowledge. Propaganda is an indirect message appealing primarily to emotion. A fallacious argument is one that tries to argue from A to B, but because it contains hidden assumptions or factual irrelevancies, reaches an invalid conclusion.Īnother kind of faulty reasoning results from substituting emotion for thought. One kind of faulty reasoning is a fallacy, a breakdown of logic. Critical thinking enables you to distinguish between fact and opinion and distinguish sound from faulty reasoning.
