That's really interesting, you maybe onto something. The number of people who have internalised the deeper understanding of something vs the number who know it in a rote memory way might be different too. I find I often casually agree with something when I'm learning it but the deep aha moment happens later when I've developed a more complete picture of what it is I'm learning, and once that happens, I really understand it. It's possible a number of people are at the yes I agree with it stage of learning about authoritarian systems etc but haven't had their aha moment yes now I really understand the meaning behind it.
