[T]he structure of the news production system is, you can’t produce evidence. There’s even a name for it … . It’s called “concision.” The kind of things that I would say on Nightline, you can’t say in one sentence because they depart from standard religion. If you want to repeat the religion, you can get away with it between two commercials. If you want to say something that questions the religion, you’re expected to give evidence, and that you can’t do between two commercials. So therefore you lack concision, so therefore you can’t talk.
I think that’s a terrific technique of propaganda. To impose concision is a way of virtually guaranteeing that the party line gets repeated over and over again, and that nothing else is heard.
