In science, parsimony is to prefer least complicated explanation for an observation. This is generally regarded as good when judging hypotheses.

The tragedy of commons
about the author [wiki]:
Garrett James Hardin (April 21, 1915 – September 14, 2003) was a leading and controversial ecologist from Dallas, Texas, who was most known for his 1968 paper, The Tragedy of the Commons. He is also known for Hardin's First Law of Ecology, which states "You cannot do only one thing", and used the ubiquitous phrase "Nice guys finish last" to sum up the "selfish gene" concept of life and evolution.[1]
<snip> The tragedy of the commons develops in this way. Picture a pasture open to all. It is to be expected that each herdsman will try to keep as many cattle as possible on the commons. Such an arrangement may work reasonably satisfactorily for centuries because tribal wars, poaching, and disease keep the numbers of both man and beast well below the carrying capacity of the land. Finally, however, comes the day of reckoning, that is, the day when the long-desired goal of social stability becomes a reality. At this point, the inherent logic of the commons remorselessly generates tragedy.
As a rational being, each herdsman seeks to maximize his gain. Explicitly or implicitly, more or less consciously, he asks, "What is the utility to me of adding one more animal to my herd?" This utility has one negative and one positive component.
1) The positive component is a function of the increment of one animal. Since the herdsman receives all the proceeds from the sale of the additional animal, the positive utility is nearly +1.
2) The negative component is a function of the additional overgrazing created by one more animal. Since, however, the effects of overgrazing are shared by all the herdsmen, the negative utility for any particular decision-making herdsman is only a fraction of 1.

The Glories of Change - Jeffrey A. Tucker - Mises Institute
http://mises.org/story/3109 --- The events on Wall Street, the collapse of Lehman and the selling off of Merrill, are magnificent and inspiring events. What we see here are examples of sweeping and fundamental change taking place, a huge upheaval that affects the whole of society, and toward the better, since what we have going on here is a massive reallocation of resources away from failing uses toward more productive uses.
