《百万大决策》的作者詹姆斯.索诺维尔基曾经说过,要得出良好的群体决策得具备四个条件:建议的多样化——每一个人都有一些私有信息,即使是一些对已知事实的反常解释;独立性——人们不会因为别人的意见而改变自己的意见;分权——没有人被强制性地做事情;汇聚——一种使得个体判断成为群体决策的机制。 James Sonovitch, author of Millions of Big Decisions, once said that there are four conditions for a good group decision-making: Proposed Diversification - Everyone has some private information, even some of them Anomalous interpretation of known facts; Independence - People do not change their opinions because of other people’s opinions; Decentralization - No one is forced to do things; Convergence - A mechanism that makes individuals judge as group decisions .
