论文摘要
时间结构化的私人和社会信息如何形成集体决策？为了解决这个问题，我们考虑了一个理性代理网络，他们独立积累了私人证据，以触发达到阈值时的决定。当整个网络看到时，第一代理的选择会引发一波新决定。后来的决定的影响较小。在异质网络中，最初的决定是由几乎没有证据的冲动人员迅速做出的，但是，即使是错误的，也可以向其他所有人揭示正确的选择。我们得出的结论是，由不同个体组成的群体比同质的群体可以做出更有效的决策。
How does temporally structured private and social information shape collective decisions? To address this question we consider a network of rational agents who independently accumulate private evidence that triggers a decision upon reaching a threshold. When seen by the whole network, the first agent's choice initiates a wave of new decisions; later decisions have less impact. In heterogeneous networks, first decisions are made quickly by impulsive individuals who need little evidence to make a choice, but, even when wrong, can reveal the correct options to nearly everyone else. We conclude that groups comprised of diverse individuals can make more efficient decisions than homogenous ones.
