One thing that grinds my gears is how the article is shoehorning all these examples of zero-sum bias into a precisely zero-sum situation. It doesn't actually have to be zero-sum for that "bias" to become rational. For example, prisoner's dilemma (which would actually better describe most of the situations put forth in the article).
