"attempt to" is a key phrase in your question. I don't see much trouble with openly displayed intelligence, as long as it's actually intelligent (correct, and directed to an agreed shared goal). Nobody much cares for show-offs or useless knowledge.

I do see a bit of resistance to "weird", which often comes with analysis. Much of the time, but not always, that's because the supposed-intelligent participant has done only a superficial analysis and not really attempted to understand the equilibrium that is the status quo.

High-school is ... unrelated to the real world, for which I am grateful. Don't extrapolate from what is effectively a Robbers Cave experiment that kids impose on each other in the absence of any meaningful effort/skill rewards.
