摘要:The authors analyzed data from multiple large-scale randomized experiments on LinkedIn’s People You May Know algorithm, which recommends new connections to LinkedIn members, to test the extent to which weak ties increased job mobility in the world’s largest professional social network. The experiments randomly varied the prevalence of weak ties in the networks of over 20 million people over a 5-year period, during which 2 billion new ties and 600,000 new jobs were created. The results provided experimental causal evidence supporting the strength of weak ties and suggested three revisions to the theory. First, the strength of weak ties was nonlinear. Statistical analysis found an inverted U-shaped relationship between tie strength and job transmission such that weaker ties increased job transmission but only to a point, after which there were diminishing marginal returns to tie weakness. Second, weak ties measured by interaction intensity and the number of mutual connections displayed varying effects. Moderately weak ties (measured by mutual connections) and the weakest ties (measured by interaction intensity) created the most job mobility. Third, the strength of weak ties varied by industry. Whereas weak ties increased job mobility in more digital industries, strong ties increased job mobility in less digital industries.

弱联系(weak ties)是指人们互动较少、感情较弱的那些人际关系。理论认为,弱联系在社交网络间的信息传递中发挥了重要作用,但很少有实验能够验证这一点。近日,发表于《科学》的一项研究显示,当某人想要找到一份新工作时,那些不常联系的“弱联系”要比亲密的朋友或家人更有帮助。


研究者利用了领英(Linkedln)“你可能认识的人”功能,这个功能会向用户推荐新好友(network)。研究者通过调整该算法,随机改变了超2000万领英成员的推荐数据,并据此分别测试强联系和弱联系对用户工作调整的影响。结果显示,相比强联系,弱联系的确在一定程度上帮助个体找到了更理想的工作岗位,但之后的影响会递减。另外,弱联系的影响力也因行业而异——弱联系可以更好地帮助个体找到高科技行业的工作,但对低技术含量的行业影响较小。
