我们研究人类活动模式对信息传播的影响。为此，我们进行了一项病毒式电子邮件实验，涉及31183人，我们能够通过社交网络跟踪特定的信息。我们发现，与传统模型相反，信息传播的速度出乎意料地慢。通过使用一个分支模型，准确地描述了实验，我们发现，在响应时间的大的异质性是负责缓慢的动态信息在集体层面。鉴于我们的结果的一般性，我们讨论了这一发现的重要意义，同时模拟人类动力学集体现象。
We study the impact of human activity patterns on information diffusion. To this end we ran a viral email experiment involving 31 183 individuals in which we were able to track a specific piece of information through the social network. We found that, contrary to traditional models, information travels at an unexpectedly slow pace. By using a branching model which accurately describes the experiment, we show that the large heterogeneity found in the response time is responsible for the slow dynamics of information at the collective level. Given the generality of our result, we discuss the important implications of this finding while modeling human dynamical collective phenomena.
