Yes, I’ve encountered that attitude too. I even ended up getting caught up in it myself, with disastrous consequences.
I don’t think it’s a specifically YEC thing though. Rather, it’s a misunderstanding and misapplication of passages such as 1 Corinthians 1:18-31. People read about God choosing the foolish things of the world to shame the wise and try to appropriate it for themselves, by dropping out of school or university, dumbing things down, or whatever. But they completely miss the point of these verses. They are talking about people who lost out on a good education due to discrimination, poverty, war, illness, neurodiversity, or other factors beyond their control. Consciously and deliberately lowering one’s intellectual standards by choice on the other hand is not just foolishness; it is laziness, recklessness, slovenliness and dishonesty.
