7 88CF452-E7F2-99DF-3EBC599C3A9F1C6FScientific American reports about a mathematical model, describing rather common social behaviour: "When humans live together, they work together — whether they are building cities or just trying to snag some grub for dinner. But if you can still reap the benefits of contributions to the greater good without lifting a finger yourself, why would you not choose that option? Chances are you tow the line out of fear of being punished." A very interesting read, and one of the findings was that "...the punishers must dominate to sustain the success of a collective activity." http://www.sciam.com/article.cfm?articleID=788CF4 5 2-E7F2-99DF-3EBC599C3A9F1C6F&pageNumber=2&catID=1 for the non-print-version."
