Very interesting. Can anyone recommend a good (light, if possible) introduction to game theory?
One of the most basic 'games' in game theory is called the Prisoner's Dilemma:

Basically, the idea here is to figure out your best strategy for the 'game' (which really means any situation where you need to make a decision), given that the other "players" don't cooperate with you in any way (i.e. you assume they are going to act in their own self-interest).

The most basic successful strategy for the Prisoner's Dilemma is called "Tit-for-Tat", in which you always choose the "altruistic" option, unless the other player chose against you last time.

GAME THEORY A Nontechnical Introduction by Morton D. Davis is great.
Personally, I plan on pursuing a career where game theory would play an important role in my research or work (teaching or intelligence research).

In many ways it's the science of cause-and-effect (hence why the Tit-for-Tat game solution works so well). By applying the concept of how one event can determine another on a predictable basis, one can help explain and potentially solve many of the world's greatest problems.
