I find this idea genuinely terrifying. Having seen lots of factual information, you start to see where things logically fit in and you're able to deduce so much more new information, but you're also just able to tell when aunt Marge is spitting straight horseshit again.

Now imagine growing up in e.g. a creationist household, maybe even home-schooled, where you're told things just are a certain way, even though it makes absolutely no fucking sense. At no point, you start to see logical patterns. At no point, you develop an intuition for new information. And if someone bullshits you, your only 'defense' is whether you trust them on a personal level, meaning aunt Marge's horseshit is to be considered unquestionably correct. What a dismal and vulnerable position to be in.
