论文摘要
近年来，社交媒体越来越成为政治运动，尤其是选举的重要平台。仍然难以捉摸的公众话语是如何由个人社会认知偏见，决斗竞选工作和社交媒体平台之间的复杂相互作用驱动的。我们通过将2016年政治网络的转发网络与基于代理的政治舆论形成和网络结构的模型相结合，从而研究了这一复杂的社会政治过程。在这里，我们表明，个人愿意考虑的一系列政治观点是两极分化网络和回声室的出现的关键决定因素。我们还发现，在公共话语中赢得多数支持取决于运动所做的努力和反对运动的相对意识形态定位。我们的结果表明，如何将公共话语和政治两极分化如何建模为转移个人观点，不断发展的社交网络和政治运动的互动过程。
In recent years, social media has increasingly become an important platform for political campaigns, especially elections. It remains elusive how exactly public discourse is driven by the intricate interplay between individual socio-cognitive biases, dueling campaign efforts, and social media platforms. We examine this complex socio-political process by integrating observed retweet networks from the 2016 political networks with an agent-based model of political opinion formation and network structure. Here we show that the range of political viewpoints individuals are willing to consider is a key determinant in the formation of polarized networks and the emergence of echo chambers. We also find that winning majority support in public discourse is determined by both the effort exerted by campaigns and the relative ideological positioning of opposing campaigns. Our results demonstrate how public discourse and political polarization can be modeled as an interactive process of shifting individual opinions, evolving social networks, and political campaigns.
