Some scholars see game theory not as a predictive tool for the behavior of human beings, but as a suggestion for how people ought to behave. Since a strategy, corresponding to a Nash equilibrium of a game constitutes one's [[best response]] to the actions of the other players – provided they are in (the same) Nash equilibrium – playing a strategy that is part of a Nash equilibrium seems appropriate. This normative use of game theory has also come under criticism.<ref>{{cite journal |last1=Kadane |first1=Joseph B. |last2=Larkey |first2=Patrick D. |title=The Confusion of Is and Ought in Game Theoretic Contexts |journal=Management Science |date=December 1983 |volume=29 |issue=12 |pages=1365–1379 |doi=10.1287/mnsc.29.12.1365 }}</ref>
