Refine your skills of Propaganda Analysis.

"As generally understood, propaganda is opinion expressed for the purpose of influencing actions of individuals or groups... Propaganda thus differs fundamentally from scientific analysis. The propagandist tries to "put something across," good or bad. The scientist does not try to put anything across; he devotes his life to the discovery of new facts and principles. The propagandist seldom wants careful scrutiny and criticism; his object is to bring about a specific action. The scientist, on the other hand, is always prepared for and wants the most careful scrutiny and criticism of his facts and ideas. Science flourishes on criticism. Dangerous propaganda crumbles before it."
