An experimental study of collective coping with social risks.

在第一个研究中，作者采用沟通链范式(Kashima，2000)考察了他人消极行为的信息是否会通过社会网络更准确地传递。结果表明，负面信息的子集(例如，恋爱关系中的不忠)比其他类型的信息传递得更准确。在S的第二个研究中，基于多群体选择理论和文化群体选择理论，作者假设从众(频率依赖行为)可能有助于促进群体内合作。进化模拟的结果表明，群体内的合作和从众可以在群体间冲突的情况下进化。然而，随后的研究表明，反整合因子对群体合作进化有负面影响。

In this paper, the author examined human collect ive coping with social risks.In the first study, employing the communicat ion chain paradigm (Kashima, 2000), the author examinedwhether the information of other people's negative behavior would be more accurately trans mitted through a social network. The results showed that a subset of negative information (e.g., infidelity withina romantic relat ionship) was transmitted more accurately than other types of information. In the second s tudy, based on multi-group selection theory and cultural group selection theory, the author hypothesizedthat conformity (frequency-dependent behavior) may contribute to enhancing ingroup cooperation. Theresults of an evolutionary simulation revealed that ingroup cooperation and conformity can evolve under intergroup conflict . Howeve r, t he fol lowing study revealed that anti-conformity agent has negative effecton evolution of ingroup cooperation.
