通信网络的结构是团队、组织和社会解决政策、商业和科学问题的能力的重要决定因素。然而，以前的研究得出了相互矛盾的结果网络结构和性能之间的关系，找到支持的优势，良好连接的有效和连接不良的低效网络结构。在这里，我们认为，了解沟通网络如何影响群体绩效需要考虑到个别团队成员的社会学习策略。我们发现，当个体依赖于通过复制他们的联系人中最常见的解决方案来实现一致性时，高效网络的表现优于低效网络。然而，当个体通过模仿收益最高的群体成员来追随最好的成员时，低效网络是上级的。此外，依赖于基于小样本他人的一致性的群体在复杂任务中表现出色，而跟随最佳成员的群体在简单任务中表现最好。我们的研究结果调和了文献中相互矛盾的结果，并对跨学科的社会学习研究产生了广泛的影响。 以往的研究对有效或无效的网络结构在促进群体绩效方面是否更有效存在分歧。在这里，Barkoczi和Galesic证明了哪种结构是上级取决于网络中个人使用的社会学习策略。
The structure of communication networks is an important determinant of the capacity of teams, organizations and societies to solve policy, business and science problems. Yet, previous studies reached contradictory results about the relationship between network structure and performance, finding support for the superiority of both well-connected efficient and poorly connected inefficient network structures. Here we argue that understanding how communication networks affect group performance requires taking into consideration the social learning strategies of individual team members. We show that efficient networks outperform inefficient networks when individuals rely on conformity by copying the most frequent solution among their contacts. However, inefficient networks are superior when individuals follow the best member by copying the group member with the highest payoff. In addition, groups relying on conformity based on a small sample of others excel at complex tasks, while groups following the best member achieve greatest performance for simple tasks. Our findings reconcile contradictory results in the literature and have broad implications for the study of social learning across disciplines. Previous studies have disagreed over whether efficient or inefficient network structures should be more effective in promoting group performance. Here, Barkoczi and Galesic demonstrate that which structure is superior depends on the social learning strategy used by individuals in the network.
