It may also be defined as the spreading of information in order to influence public opinion and to manipulate other people's beliefs. Information can be delivered in many ways. Schoolteachers try to give accurate information to their students, and television news broadcasts attempt to provide it for their audiences. What separates propaganda from these is the quality of the information and the way it is used.
All propaganda is a systematic effort to persuade.
Thus the issue is not the truth or falsehood of what is said. The propagandist gives a one-sided message, emphasizing the good points of one position and the bad points of another position. One of the most widely used forms of propaganda in the 20th century is the political speech. Politicians running for office try to project the best possible image of themselves while pointing out all the flaws of their opponents. If the propaganda were given to only one person, that individual could disagree and present other views.
