 It is sometimes argued that evolutionary game theoretic models answer “how possibly” questions. That is, an evolutionary game theoretic model shows how some phenomenon could possibly be generated by an underlying dynamical process of interacting, boundedly rational agents. Although this is certainly the case, one might wonder whether this subtly shifts the explanatory target. Answering a “how possibly” question is most interesting when we do not know whether something is possible at all. The challenge faced by some evolutionary game theoretic accounts of social phenomena is that they answer a “how possibly” question regarding something which we already knew was possible, because the phenomenon actually exists. What we would like to know is how the answer to the “how possibly” question connects to the actual real-world processes generating the phenomenon. This suggests that evolutionary game theoretic explanations of social phenomena are, even in the best cases, incomplete.
