人类行为被认为是通过面对面的社交网络传播的，但在观察性研究中很难确定社会影响效应，在线社交网络是否也以同样的方式运作还不得而知。在这里，我们报告了一项随机对照试验的结果，该试验在2010年美国国会选举期间向6100万Facebook用户传递了政治动员信息。结果显示，这些信息直接影响了数百万人的政治自我表达、信息寻求和现实世界投票行为。此外，这些信息不仅会影响收到信息的用户，还会影响用户的朋友，以及朋友的朋友。社交传播对现实世界投票的影响大于信息本身的直接影响，而且几乎所有的传播都发生在更有可能有面对面关系的“亲密朋友”之间。这些结果表明，牢固的关系有助于在人类社交网络中传播在线和现实世界的行为。
Human behaviour is thought to spread through face-to-face social networks, but it is difficult to identify social influence effects in observational studies, and it is unknown whether online social networks operate in the same way. Here we report results from a randomized controlled trial of political mobilization messages delivered to 61 million Facebook users during the 2010 US congressional elections. The results show that the messages directly influenced political self-expression, information seeking and real-world voting behaviour of millions of people. Furthermore, the messages not only influenced the users who received them but also the users’ friends, and friends of friends. The effect of social transmission on real-world voting was greater than the direct effect of the messages themselves, and nearly all the transmission occurred between ‘close friends’ who were more likely to have a face-to-face relationship. These results suggest that strong ties are instrumental for spreading both online and real-world behaviour in human social networks.
