Propaganda is the dark side of bias. Propaganda techniques are designed to influence opinion by manipulating the truth. A propagandist is completely biased in favor of some point of view.

Knowing propaganda techniques will help you analyze webpages, understand advertising, and recognize bias when you see it.

Authors who use name-calling and strive to evoke fear are using tried and true propaganda techniques. Appealing to the group, using glittering generalizations, and relying on testimonials are very persuasive techniques, especially if the audience is unaware of how propagandists operate.
