社会聚类强化了外部影响对多数意见模型的作用

Social clustering reinforces external influence on the majority opinion model

Niels Van Santen, Jan Ryckebusch, Luis E. C. Rocha

AI总结:

研究外部影响与同伴互动在多数投票模型中的相互作用,发现社会聚类正向强化外部影响,而度异质性削弱外部力量,为企业与政策制定提供见解。

摘要:

公众意见受制于通过社交网络进行的同伴互动以及来自媒体、广告和其他行为者的外部压力。在本文中,我们研究了外部影响与同伴影响对多数投票模型的随机意见动力学的相互作用。我们引入了一个模型,其中智能体根据其局部邻域(同伴)和外部行为者在转移速率中的综合影响来更新他们的意见。在第一个模型中,外部影响仅被与外部行为者不一致的智能体所感受到(“推动策略”)。在第二个模型中,智能体受外部影响,独立于他们的意见(“助推策略”)。在这两种情况下,外部影响都增加了可能的宏观结果。这些结果由所选的影响策略决定。我们还发现,社交网络结构影响意见动力学,社会聚类正向强化外部影响,而度异质性削弱外部力量。这些发现与企业与政策制定相关,有助于理解个体群体如何对外部行为者做出集体反应。

英文摘要:

Public opinion is subject to peer interaction via social networks and external pressure from the media, advertising, and other actors. In this paper, we study the interaction between external and peer influence on the stochastic opinion dynamics of a majority vote model. We introduce a model where agents update their opinions based on the combined influence of their local neighbourhood (peers) and an external actor in the transition rates. In the first model, the external influence is only felt by agents non-aligned with the external actor ("push strategy"). In the second model, agents are affected by external influence, independently of their opinions ("nudging strategy"). In both cases, the external influence increases the possible macroscopic outcomes. These outcomes are determined by the chosen influence strategy. We also find that the social network structure affects the opinion dynamics, with social clustering positively reinforcing the external influence whereas degree heterogeneity weakens the external forces. These findings are relevant to businesses and policy making, helping to understand how groups of individuals collectively react to external actors.
