Understanding the impact of heterogeneity on the evolution of group opinions can enlighten us on how to effectively organize, redesign, and improve decision-making efficiency. This article explores mainly the effects of heterogeneity on the evolution of group opinions. It is found that the heterogeneity of individuals’ openness has an important influence on the ability to aggregate group opinions. According to the average amount of clusters and Herfindahl–Hirschman Index (HHI) under different network structures, heterogeneity often improves the ability. In addition, for the small-world network and random network, there is little difference in the aggregation ability from both the average amount of clusters and the Herfindahl–Hirschman Index. While for the regular network, the ability is obviously weaker than that of the other two. This result also shows that the randomness of interaction between members will enhance the cohesion of a group.

成员的异质性如何影响群体意见的演变？

了解异质性对集体意见演变的影响可以启发我们如何有效地组织，重新设计和提高决策效率。本文主要探讨异质性对群体意见演变的影响。发现个人开放性的异质性对聚集集体意见的能力有重要影响。根据不同网络结构下群集的平均数量和赫芬达尔·赫希曼指数（HHI），异质性通常会提高能力。另外，对于小世界网络和随机网络，聚集能力与平均簇数和Herfindahl-Hirschman指数几乎没有差异。对于常规网络，此功能显然比其他两个功能弱。
