The interesting tradeoff with beef-only thinking is: your thinking is worse (because it's expedient) while you're in conflict, and it is briefly "better" after you win and hormone-acceleration hits. But the conflicting group overall is dumber, since losers are dumber for a while.

It's a way of "shorting" collective intelligence. A tragedy of the emergent wisdom-of-crowds commons. The more exploratory a group, with higher levels of private knowledge, the greater the loss/cost of beef-only thinking.
