In humans? No one knows. My best guess at the moment for the lowest level of model choice is some form of decentralised selectionist system, that is much as decision theoretic construct as real evolution is.
We do of course have higher level model choosing systems that might work on a decision theoretic basis, but they have models implicit in them which can be flawed.
