Yeah, it's interesting that people will proudly admit "I can't do math" but you don't nearly as often hear them say "I don't understand politics, government, or world affairs." People will do their damnedest to appear knowledgeable about those things.
That's true. “I don't really understand national politics in any deep way,” is something I've said many times and has been responded to often with “me neither”, but I'm quite sure had I not said it, the person would've kept quiet about their ignorance and feigned insight in other conversations.
