Right but that is actually a strategy that makes a lot of sense. You will likely fit in well with your peers and you will likely feel comfortable with your beliefs and "knowledge".
Maybe we could call it a local maximum, personally, although something of a disaster, societally.
I don't think having a lot of information is intelligence. Plenty of medieval peasants were stupid and a small percentage could combine information into new things for the idiots around them to repeat. During a short period copied behavior traveled less well and it was more obvious how stupid the median person was.
I'd argue that an idiot peasant who sees something that works and adopts it is smarter than the anti science people we have yammering on social media right now!
However, I do believe most people are uncurious. Since information is so cheap, it seems many people just reach for what feels good and doesn't risk their existing worldviews.
