They are familiar scenes: politicians bemoaning the death of family values only for extramarital affairs to be unveiled or politicians preaching financial sacrifice while their expense accounts fatten up.
Moral corruption and power asymmetries are pervasive in human societies, but as it turns out, that may not be such a bad thing.
Francisco beda, an evolutionary biology professor at the University of Tennessee, Knoxville, and Edgar Duez of Harvard University found that power and corruption may play a role in maintaining overall societal cooperation.
A report of their research is published in the journal Evolution and can be viewed online at http://onlinelibrary.wiley.com/journal/10.1111/%28ISSN%291558-5646/earlyview.
Using game theory, beda and Duez looked at what causes individuals in society to cooperate even though those in charge display some level of corruption. They developed a model that allows individuals who are responsible for punishing noncooperators (e.g., law enforcers and government officials) to fail to cooperate themselves by acting in a corrupt manner. They also considered the possibility that these law enforcers, by virtue of their positions, are able to sidestep punishment when they are caught failing to cooperate.
What they found is that the bulk of society cooperates because there are law enforcers forcing them to stay in line. People tend to cooperate because they do not want to get punished.
Even if the law enforcers consider themselves above the law and behave in a corrupt way, overall societal cooperation is maintained as long as there is a small amount of power and corruption. However, if the law enforcers have too much power and corruption runs rampant, overall societal cooperation breaks down.
beda explained how it works:
"Law enforcers often enjoy privileges that allow
