Harvard Business Review: "The Unselfish Gene" http://hbr.org/2011...
"Ross and his collaborators told half the players in their experiments that they were playing the Community Game and the other half that they were playing the Wall Street Game. The two groups were identical in all other respects. Yet, in the Community Game group, 70% started out playing cooperatively and continued to do so throughout the experiment. In the Wall Street Game group, the proportions were reversed: 70% of the players didn’t cooperate with one another. Thirty percent started out playing cooperatively but stopped when the others didn’t respond." ! - Ruchira S. Datta
