Often someone will make a comment along these lines: establishment individuals can't or don't really believe the piles of BS they spew--all that globalism, militarism, credentialism, cultural Marxism, and robber baronism. High IQ establishment individuals can't be that willfully, mindbogglingly wrong, can they?
Oh, yes they do believe that crap.
How do I know?
Because when they talk about the views of non-establishment individuals, their arguments make them appear as neophytes on outside views, not even counting the straw person attacks, as if, at best, they merely skimmed a Wikipedia entry on outside views.
If they were secretly fact facers, they would secretly read the arguments and talk the language.
If someone said, "Bob is secretly a chemical engineer," but every time you heard Bob talk about chemical engineering he sounded like a five-year-old talking about chemical engineering, you wouldn't believe Bob was secretly a chemical engineer.
There's also some research.
The other alternative is that establishment individuals are the world's greatest method actors, deliberately making themselves look like unmitigated neophytes on outside views. Not likely.
Yes, it seems weird that establishment humans can act so dignified and articulate, yet spout one fallacy after another. But the human unwillingness to find and face moral facts, when doing so conflicts with perceived self-interest, is astronomical.
