Thank you, that was an enjoyable read. That we can actually accomplish the methodology described in the conclusion - generate numbers out of iterated game theory, match those numbers against quantities observed in the brain via fMRI - is setting off science-is-awesome fuzzies.

This review article may be particularly interesting for those who suspect that game theory may play a major role in human value, perhaps even in ways that would make it more intuitively plausible that reasonable value extrapolation algorithms can be developed.
