This is a very interesting hypothesis on the evolutionary origins of anti-intellectualism! So I agree that a homogeneous population will be much better at communication (no one needs to "talk" down to each other). But given that social animals often form a hierarchy, do you think it still matters as much? The "smarter" ones can get others to follow him without the rest understanding his internal thought process. Group selection should vastly favor tribes that are good at producing these intellectual leaders then.
