"My guess is that you would find that the intellectual elite is the most heavily indoctrinated sector. It's their role as a secular priesthood to really believe the nonsense that they put forth. Other people can repeat it, but it's not that crucial that they really believe it. But for the intellectual elite themselves, it's crucial that they believe it because, after all, they are guardians of the faith. Except for a very rare person who's just an outright liar, it's hard to be a convincing exponent of the faith unless you've internalized it and come to believe it."
