Most NPC like take.
Look I get your sentiment. Sometimes it feels like you're the only thinking, conscious being. Surrounded by beings who fundamentally cannot understand that A –> B does not imply B –> A. Beings that say things that are so obviously non-sequiturs or contradictory.
But calling people NPCs is the most NPC thing you can do. There is more to people than logical reasoning and these things often impede or completely block reasoning. Very intelligent people sometimes say the most grotesque things. People turn mad and mad people sometimes get their head set straight.
Sometimes it's not so much about the pure ability to reason but the goal of that person and whether they see understanding something or trying to understand it as helpful towards that goal.
I do agree though that the more intelligent someone is the less likely it is that other things will block their intelligent ability and the harder it is for them to fool themselves into believing absurd nonsense and to blind themselves from apparent truth.
Sometimes after talking with someone – or rather trying to but ending up only talking to them because they just do not manage to understand what I'm saying or to engage with it in any way – I wonder how they manage to get through every day life as that requires solving way more complex practical problems. Yet they do.
