Human behavior is a large part of the complexity because we try to use things like game theory to predict how someone will act based on a confined set of conditions which totally ignore the very long game which has been playing from long in the past and will continue long in the future. There are too many factors to account for which can make an actor appear irrational given the posited conditions, however the truth is there can never be a rational actor until we map every input and interaction in someones life. This is why the idea of a rational actor is horseshit.
Nick Szabo did a recent post that covers this:
A small-game fallacy occurs when game theorists, economists, or others trying to apply game-theoretic or microeconomic techniques to real-world problems, posit a simple, and thus cognizable, interaction, under a very limited and precise set of rules, whereas real-world analogous situations take place within longer-term and vastly more complicated games with many more players: "the games of life".
