From StrategyPage: The Golden Age Of Artful Dodging
August 26, 2013: Over the last few decades there has been an explosion in the number of news media outlets. With this has come fierce competition and more interest in gaining an audience than in reporting the news accurately. That has led to there being more propaganda than news out there. That wasn’t a difficult leap to make because in the last century some powerful propaganda methods and techniques for controlling public opinion were developed. Many of these techniques are actually ancient, but never before have they been used so intensively, persistently and in greater variety.
But this sort of thing goes back a long way. Two thousand years ago the ancient Romans saw schools of rhetoric as the best place to send bright young men with potential to be leaders. There schools of rhetoric taught how to use logic and persuasion to make a point and convince people. Some of books those students used are still studied and many of these ancient techniques evolved and mutated into modern propaganda and media spin. The schools at Rhodes were, for well-off ancient Romans, sort of a university education.
Has a good(horrifying) list of techniques, many in use by the media outlets we all listen to…even bloggers and the like, who may use the techniques without knowing they’re techniques.
