This altruism continued over several degrees of separation from the original points-sharing player, and persisted over time -- recipients of a single kindness continued sharing with others over multiple turns in the game.
"Each additional contribution a subject makes to the public good in the first period is tripled over the course of the experiment by other subjects who are directly or indirectly influenced to contribute more as a consequence," the authors wrote.
The results, published in 2010 in the journal Proceedings of the National Academy of Sciences, provide some hope that crowds might be just as susceptible to contagious positive behaviors as they are to negative ones.
