Even for something as simple as the prisoner's dilemma, there's quite a bit of variety in both situations and agents, so how do you decide what the "optimal" game theoretic strategy is for actual people in much more complex situations in reality? I'm not sure that it's tricking people, because society is people. I mean, suppose that people aren't tricked into being good, and then society is worse off. How could everyone in the worse off society be doing better than everyone in the better off society? This doesn't seem like a trick to me so much as adopting a different perspective.
