论文摘要
批判性思维和怀疑是人们可以用来防止谣言传播,假新闻和错误信息的基本机制。我们考虑了一个简单的模型,在这种模型中,持怀疑态度的谣言以前没有与谣言接触的代理商可能会说服吊具停止活动,或者一旦接触到谣言,就决定不传播它,因此,例如,事实核对。我们扩展了对这两种机制(主动和被动怀疑主义)的综合作用的先前平均场分析,以包括空间相关性。可以通过对近似进行分析,或在不同网络上模拟基于代理的版本。我们的结果表明,尽管在均值场上,散布器和易感之间没有共存(尽管取决于参数,但在包括空间相关性的情况下,可能会取决于原始性,但由于删除试剂提供的隔离物提供了保护作用,因此可以存在共存。
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.
