摘要翻译：
文化趋势和流行周期可以在我们周围观察到，但我们关于社会影响和身份表达的理论并不能解释是什么使这些复杂的、往往不可预测的社会动态永久化。我们提出了一种社会认同表达理论，其基础是在一个社会网络中，一个人的邻居之间保持一致和独特性的动机是对立的，但不是相互排斥的。然后，我们对这些动机所产生的社会动力进行建模。我们发现动力学通常进入随机游动或随机极限环，而不是收敛到静态平衡。我们还证明了在没有社会网络结构或唯一性动机的情况下，合理的自适应动力学必然会收敛到均衡。因此，我们表明，细致入微的心理学假设（认识到对独特性的偏好以及一致性）和现实的社会网络结构对于解释复杂的、不可预测的文化趋势是如何出现的都是必要的。

英文摘要：
  Cultural trends and popularity cycles can be observed all around us, yet our theories of social influence and identity expression do not explain what perpetuates these complex, often unpredictable social dynamics. We propose a theory of social identity expression based on the opposing, but not mutually exclusive, motives to conform and to be unique among one's neighbors in a social network. We then model the social dynamics that arise from these motives. We find that the dynamics typically enter random walks or stochastic limit cycles rather than converging to a static equilibrium. We also prove that without social network structure or, alternatively, without the uniqueness motive, reasonable adaptive dynamics would necessarily converge to equilibrium. Thus, we show that nuanced psychological assumptions (recognizing preferences for uniqueness along with conformity) and realistic social network structure are both necessary for explaining how complex, unpredictable cultural trends emerge.
