人类社会包括各种各样的社会关系。朋友、家人、商业同事和网络联系人都可以为一个人的社交生活做出贡献。个人在不同的领域可能表现不同，但一个领域的成功可能会带来另一个领域的成功。在这里，我们使用多层网络来研究这个问题，以模拟社会互动的多个领域，其中个体经历不同的环境并可能表达不同的行为。我们提供了一个数学分析，发现层之间的耦合倾向于促进亲社会行为。即使亲社会性在每一层都不受欢迎，多层耦合也能同时促进其在所有层的扩散。我们将此分析应用于六个现实世界的多层网络，范围从赞比亚社区的社会情感和专业关系，到学术大学内的在线和离线关系。我们讨论了我们的结果的含义，这表明在一个领域的相互作用的微小修改可能催化在不同领域的亲社会性。我们的社会生活涉及许多不同领域的互动，包括家庭成员、朋友、同事和在线联系人的网络。Su等人表明，具有多个互动领域的网络倾向于促进合作行为。
Human societies include diverse social relationships. Friends, family, business colleagues and online contacts can all contribute to one's social life. Individuals may behave differently in different domains, but success in one domain may engender success in another. Here, we study this problem using multilayer networks to model multiple domains of social interactions, in which individuals experience different environments and may express different behaviours. We provide a mathematical analysis and find that coupling between layers tends to promote prosocial behaviour. Even if prosociality is disfavoured in each layer alone, multilayer coupling can promote its proliferation in all layers simultaneously. We apply this analysis to six real-world multilayer networks, ranging from the socio-emotional and professional relationships in a Zambian community, to the online and offline relationships within an academic university. We discuss the implications of our results, which suggest that small modifications to interactions in one domain may catalyse prosociality in a different domain.Our social lives involve interactions in many different domains, including networks of family members, friends, colleagues and online contacts. Su et al. show that networks with multiple domains of interaction tend to promote cooperative behaviour.
