我也来说说。有一次在卫生间里丢了钱包,到了晚上下班的时候才发现。当时身上另无分文,而且刚刚到澳洲1个月,很多心烦的事情都没理顺,又丢了钱包和所有银行卡,信用卡之类,心情糟透了。和单位里的人借了5块钱,跳上电车才发现只能用硬币买票。旁边一个OZ妹妹看我焦急,拿出一把硬币来说送给我了,让我买票。我谢谢她,可是数数也不够买票,所以又还给了她。然后我就无望的向车里走去,看看能能向谁换点钱。问了几个都没有那么多零钱。正要放弃,回过身一个看起来是ABC的妹妹已经准备好了5块钱的零钱给我。我那个感激啊。刚刚买了票,不到一站路,就有查票的上来,惊险。要真碰到查票的,这种情况也说不清楚。晚上回去委屈的哭了好一会,觉得来了后什么也不顺,还丢了钱包,又要挂失所有的卡。第二天到了单位,侥幸去招领处看看了看,果然有人捡到我的钱包,而且就是招领处的人捡的!虽然她们问了我仔细情况核实无误了才还给我,我也心情大好。总算是一场虚惊。所以现在我要是碰到人买票没钱之类的事,也一定解囊相助,呵呵。
还有,贴给大家一篇文章看。科学研究证明,一个人要是受到的别人的帮助,她/他就很可能在别的事情上去帮别人。这样的话,整个社会就会越来越多的热心人。所以,大家莫以善小而不为。不要觉得自己的力量太小,做一点事改变不了社会。其实如果大家每人都能做一点好事,这些好事就会成几何倍数的去感染生活中的别人,形成一种你无法想象的力量。
文章附件太大,刚刚试了贴不上去,那就给大家看个abstract吧,有兴趣的话可以自己查到这篇文章或者向我索要全文。
Cooperative behavior cascades in human social networks

Abstract:
Theoretical models suggest that social networks influence the evolution of cooperation, but to date there have been few experimental
studies. Observational data suggest that a wide variety of behaviors may spread in human social networks, but subjects in such
studies can choose to befriend people with similar behaviors, posing difficulty for causal inference. Here, we exploit a seminal set of
laboratory experiments that originally showed that voluntary costly punishment can help sustain cooperation. In these experiments,
subjects were randomly assigned to a sequence of different groups to play a series of single-shot public goods games with strangers; this
feature allowed us to draw networks of interactions to explore how cooperative and uncooperative behaviors spread from person to
person to person. We show that, in both an ordinary public goods game and in a public goods game with punishment, focal individuals
are influenced by fellow group members’ contribution behavior in future interactions with other individuals who were not a party to
the initial interaction. Furthermore, this influence persists for multiple periods and spread sup to three degrees of separation(from person to person to person to person). The results suggest that 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. These results show experimentally that cooperative behavior cascades in human social networks. |
