There is only a conflict between the predictions ("overconfidence is a benefit" and "underconfidence is a benefit"), if the evolutionary situations are indistinguishable.

If the organism can distinguish the different kinds of games, we may have a single, nuanced prediction; it will be overconfident in these situations and underconfident in these other situations.

I'm not recalling the structure of the ev. psych. / game theory examples that predict overconfidence. Could someone remind me or point me?
