 In evaluating Henrich et al.’s interpretation of these data, we should first note that no axioms of RPT, or of the various models of decision mentioned in  Section 8.1,  which are applied jointly with game theoretic modeling to human choice data, specify or entail the property of narrow selfishness. (See  Ross (2005a)  ch. 4;  Binmore (2005b)  and  (2009);  and any economics or game theory text that lets the mathematics speak for itself.) Orthodox game theory thus does not predict that people will play SPE or NE strategies derived by treating monetary payoffs as equivalent to utility.  Binmore (2005b)  is therefore justified in criticizing Henrich et al for rhetoric suggesting that their empirical work embarrasses orthodox theory.
