Not sure if this would impact academia all that much since those "pompous" scholars are just a tiny minority. I don't think academia's problem lies in individuals being problematic anyways but rather on a structural level. Egoistic, shortsighted and competitive behavior is strongly incentivized. And people that don't fit that mold get burned out pretty quickly. I think opposite to your argument it is rather an indication of how good human nature can be that academia is still working on such a collaborative and communicative basis despite capitalist and neoliberal pressures.

Sounds like you had a bad experience in academia. Most academics I know are pretty thoughtful.

every pompous ass my-shit-don’t-stink scholar

Are you talking about the kind that wins a Nobel and suddenly believes they're the expert on everything, or you casting a wider net?
