Joseph Goebbels, Minister of Propaganda for Adolf Hitler, created the "Basic Principles" of propaganda. I think you'll find this interesting...
* Avoid abstract ideas... appeal to the emotions.
* Constantly repeat just a few ideas. Use stereotyped phrases.
* Give only one side of the argument.
* Continuously criticize your opponents.
* Pick out one special "enemy" for special vilification.
Goebbels' Principles of Propaganda
* Propagandists must have access to intelligence concerning events and public opinion.
* Propaganda must be planned and executed by only one authority.
* The Propaganda consequences of an action must be considered in planning that action.
* Propaganda must affect the enemy's policy and actions.
* Declassified, operational information must be available to implement a propaganda campaign.
* To be perceived, propaganda must evoke the interest of an audience and must be transmitted through an attention-getting medium.
* Credibility alone must determine whether propaganda output should be true or false.
* The purpose, content, and effectiveness of enemy propaganda; the strength and effects of an expose'; and the nature of current propaganda campaigns determine whether enemy propaganda should be ignored or refuted.
* Credibility, intelligence, and the possible effects of communicating determine whether propaganda materials should be censored.
* Material from enemy propaganda may be utilized in operations when it helps diminish that enemy's prestige or lends support to the propagandist's own objective.
* Black rather than white propaganda must be employed when the latter is less credible or produces undesirable effects.
* Propaganda may be facilitated by leaders with prestige.
* Propaganda must be carefully timed.
* Propaganda must label events and people with distinctive phrases or slogans.
* Propaganda to the home front must prevent the raising of false hopes which can be blasted by future events.
* Propaganda to the home front must create an optimum anxiety level.
* Propaganda to the home front must diminish the impact of frustration.
* Propaganda must facilitate the displacement of aggression by specifying the targets for hatred.
* Propaganda cannot immediately affect strong counter-tendencies; instead it must offer some form of action or diversion, or both.
