Gustavo, I'm not sure I understand how my math was wrong, but it's likely since I am mathematically impaired. However, I think our points are the same: In a game with a fixed amount of money to go around, any decrease in someone else's amount is de facto an increase in your amount. The experiment sets up a mercantilist world, where "impoverish your neighbor" is equivalent to "make yourself richer." That as a matter of history the mercantilists proposed policies aimed at maximizing their share of a fixed amount of "wealth" resembling the "irrational" actions of the subjects of this experiments is evidence of the consistency with which the mercantilists worked out the implications of the assumption that the amount of wealth in the world was fixed in advance. Does this accurately describe the experiment in question, and explain why the subjects' seemingly irrational actions were really rational? Plus, on this view, we don't have to come up with some alternate theory to explain why people are both irrational and cruel. Eric McDaniel Graduate Student, University of Tulsa
