Well, the summary makes it clear that the traditional model of human interactions -- that they are driven by personal self-interest -- is actually inaccurate in an important respect.

What this paper asserts is that people stop altruistic cooperation to the degree they perceive unfairness in the sanctions of the justice process, or the rules of play. The authors extrapolate that this princiople works in all domains of human relationship -- people are less willing to play if they perceive injustice in the rules.

This is a significant piece of work because it lends some scientific credibility to the concept that there is an inherent sense of justice in human makeup.

Well, I see it as significant anyway! :>) Sorry I don't have access to the whole article, or I would be able to be more precise. Please ask Wolfgang not to beat on me! :>)
