In a way, the censorship in US academia is worse than the Soviet kind. The Soviet censors were mostly dumb, uneducated people, and it wasn’t all that hard to pull wool over their eyes and make them think you are saying the opposite of what you were. Writer Vera Ketlinskaya, for instance, created a very realistic and poignant depiction of the horrors experienced by young people in Stalin’s industrialization projects. It was investigative reporting of the highest caliber. And she got Stalin’s Award in literature for it because she was smart about how she framed the story.
We don’t have any dumb bureaucrats censoring our work. We censor each other during the peer-review process. This means that the people keeping you in tune with the party line are very smart. If you hide your ideas so well that even they can’t find them, then nobody else will find them either.
