怀疑论与谣言传播:空间相关性的作用

Skepticism and rumor spreading: the role of spatial correlations

Marco Antonio Amaral, W. G. Dantas, Jeferson J. Arenzon

摘要:

批判性思维和怀疑主义是防止谣言、假新闻和错误信息传播的基本机制。我们考虑一个简单的模型,在该模型中,代理人没有以前接触的谣言,怀疑导向,可能会说服传播者停止他们的活动,或者,一旦暴露于谣言,决定不传播它作为一个结果,例如,事实核查。我们扩展了以前的,平均场分析这两种机制,主动和被动的怀疑,包括空间相关性的综合效果。这可以通过对近似进行分析,或者在不同的网络上模拟基于代理的版本。我们的研究结果表明,虽然在平均场有没有共存的扩散器和bistable之间(虽然,根据参数,可能会有双稳态取决于初始条件),当空间相关性包括在内,由于保护作用的隔离所提供的删除代理,共存是可能的。

英文摘要:

Critical thinking and skepticism are fundamental mechanisms that one may use to prevent the spreading of rumors, fake-news and misinformation. We consider a simple model in which agents without previous contact with the rumor, being skeptically oriented, may convince spreaders to stop their activity or, once exposed to the rumor, decide not to propagate it as a consequence, for example, of fact-checking. We extend a previous, mean-field analysis of the combined effect of these two mechanisms, active and passive skepticism, to include spatial correlations. This can be done either analytically, through the pair approximation, or simulating an agent-based version on diverse networks. Our results show that while in mean-field there is no coexistence between spreaders and susceptibles (although, depending on the parameters, there may be bistability depending on the initial conditions), when spatial correlations are included, because of the protective effect of the isolation provided by removed agents, coexistence is possible.
