I’ve recently been reading more and more of a great game theory blog by the Theory, Evolution, and Games Group. That does not mean that I’ve forgotten to write my mathematically complex blog post on mixed strategies and the proof of the existence of the Nash Equilibrium in all normal games with a finite number of players and strategies. The post is certainly forthcoming.

However, today I would like to share with you a blog post on the “irrational” side of game theory. (Link below.) Although people have been shown to perform as very “rational” (in the most game theoretical sense), utility driven players as a group, we cannot deny that the individual is driven by more than the thought of pure utility maximization. The individual often deludes herself in seeking to cooperate with other players and believes in the existence of a cooperative environment which does not exist. The player can also act perfectly rational in all strategic games but miss the irrational yet cooperative strategies dealt at him that could increase the utilities of all players. But I am speaking in non-mathematical terms, and this is after all a math blog. Perhaps I will investigate “irrational” game theory myself in a future post, but, for now, the post below offers a very enriching perspective on this topic.

Evolving useful delusions to promote cooperation.
