Propaganda as truth?

Most of the population is only knowledgable on what the leaders and administration informs them on. Even many educated people are directed this way. Unfortunatly one of the negative aspects of mass media is that information can be controlled. As shown in Jowett and O'Donnell's Propaganda and Persuasion (pg. 30)

"Techniques of informative communication are also used in gray and black propaganda, but the information is not likely to be accurate or even based in reality. The propaganda
bureau of Nazi Germany was known as the 'Ministry of Information', an excellent example of black propaganda parading as information."

Even today, we are usually only as informed as our sources want us to be. In Nazi Germany, most everyday citizens did not know all of the evil crimes being committed by Hitler and his regime. What most people knew were the positive image he portrayed of the German people, as seen in this advertisement.
