Initially cooperative societies devolve toward corruption, but introducing small "payments" in conjunction with punishment can lead to stable, righteous societies, according to a modeling study published Sep. 12 in the open access journal PLOS ONE.
It has been difficult to fully dissect the interplay between cooperation, corruption, and punishment in determining societal wellbeing, but the authors of the current study, led by Edgar Duenez-Guzman of Harvard University, found that payments such as increases in social status, combined with strong egalitarian punishments, can eradicate corruption.
Moreover, once corruption has been eradicated, it can be held at bay indefinitely, even if power inequalities return.
