从假新闻到创新技术,许多传染物通过社会强化过程像复杂传染一样传播,其中多次接触不同于长时间接触单一来源。相反,埃博拉或麻疹等生物病原体通常被认为是像简单传染一样传播。在此,我们证明一旦多种传染物相互作用,这些不同的传播机制在群体层面可能具有难以区分的动态。在社会背景下,我们的研究结果凸显了在一个无数的思想、模因和行为相互作用的世界中,识别和量化传播机制(如社会强化)的挑战。在生物背景下,这种类比使得可以利用复杂传染来有效地量化传染病之间的非平凡相互作用。
From fake news to innovative technologies, many contagions spread as complex contagions via a process of social reinforcement, where multiple exposures are distinct from prolonged exposure to a single source. Contrarily, biological agents such as Ebola or measles are typically thought to spread as simple contagions. Here, we demonstrate that these different spreading mechanisms can have indistinguishable population-level dynamics once multiple contagions interact. In the social context, our results highlight the challenge of identifying and quantifying spreading mechanisms, such as social reinforcement, in a world where an innumerable amount of ideas, memes and behaviors interact. In the biological context, this parallel allows the use of complex contagions to effectively quantify the non-trivial interactions of infectious diseases.
