一句话总结

本文表明,分层的社会影响——即个体通过不同主题的专属网络进行互动——即使在文化特征较少且存在文化漂移的情况下,也能实现稳健的多元文化共存。研究发现,各层之间的结构冗余决定了文化共存的关键阈值,低冗余导致无论特征数量多少,都能维持持久的多元文化状态。

ABSTRACT

Why is our society multicultural? Based on the two mechanisms of homophily and social influence, the classical model for the dissemination of cultures proposed by Axelrod predicts the existence of a fragmented regime where different cultures can coexist in a social network. However, in such model the multicultural regime is achievable only when a high number of cultural traits is present, and is not robust against cultural drift, i.e. the spontaneous mutations of agents' traits. In real systems, social influence is inherently organised in layers, meaning that individuals tend to diversify their connections according to the topic on which they interact. In this work we show that the observed persistence of multiculturality in real-world social systems is a natural consequence of the layered organisation of social influence. We find that the critical number of cultural traits that separates the monocultural and the multicultural regimes depends on the redundancy of pairwise connections across layers. Surprisingly, for low values of structural redundancy the system is always in a multicultural state, independently on the number of traits, and is robust to the presence of cultural drift. Moreover, we show that layered social influence allows the coexistence of different levels of consensus on different topics. The insight obtained from simulations on synthetic graphs are confirmed by the analysis of two real-world social networks, where the multicultural regime persists even for a very small number of cultural traits, suggesting that the layered organisation of social interactions might indeed be at the heart of multicultural societies.

研究动机与目标

  • 解释为何在理论模型预测其脆弱性的情况下,多元文化主义在现实社会中仍能持续存在。
  • 研究社会影响的分层结构如何影响文化多样性和共识形成。
  • 确定在文化漂移和特征数量较少的情况下,分层影响是否能稳定多元文化结果。

提出的方法

  • 将社会影响建模为多个相互关联的层,每一层代表一种不同的互动主题。
  • 扩展阿克塞尔罗德的文化传播模型,引入具有主题特异性连接的分层网络。
  • 在具有不同层间结构冗余水平的合成网络上模拟文化动态。
  • 分析在冗余程度下,实现多元文化与单一文化制度所需的文化特征临界数量。
  • 使用现实世界社交网络数据验证结果,评估在特征数量较少时多元文化持续存在的可能性。

实验结果

研究问题

  • RQ1社会影响的分层组织如何影响多元文化主义的出现与稳定性?
  • RQ2层间结构冗余在决定单一文化与多元文化制度之间转变中的作用是什么?
  • RQ3当影响具有分层结构时,即使文化特征数量很少,多元文化主义是否仍能持续存在?
  • RQ4文化漂移如何影响分层网络中多元文化状态的稳定性?
  • RQ5现实世界社交网络在特征数量较少时,在多大程度上表现出模型预测的稳健多元文化状态?

主要发现

  • 在层间结构冗余较低时,系统无论文化特征数量多少,均保持多元文化状态。
  • 在低冗余的分层网络中,多元文化主义对文化漂移具有鲁棒性,这与经典模型不同。
  • 随着层间连接冗余的降低,实现多元文化主义所需的文化特征临界数量显著减少。
  • 分层影响使得不同主题上可共存不同的共识水平,真实反映了现实世界的文化多样性。
  • 对现实世界社交网络的分析证实,即使文化特征极少,多元文化主义仍能持续存在,支持了该模型的有效性。
