基于个体差异的报童群体决策研究

通过实验研究群体决策和大五人格对报童订购的影响。研究表明大五人格中开放性维度能很好地预测个体和群体决策者的订购行为。在个体实验中，开放性越高的个体更不易产生锚定效应，其他四种人格特性与锚定偏差无显著关系；在群体实验中，群体的开放性得分均值、群体中高开放性成员所占的比例与锚定偏差呈负相关关系。通过比较两种实验结果，发现群体锚定倾向明显小于个体锚定倾向，而群体决策并没有优于个体决策。该研究结果对企业人员招聘、构建决策团队及降低决策偏差有一定参考价值。

The Research on Newsvendor Decision Making Based on Individual Difference

In this paper we investigate the effect of group decision-making and big-?ve personality on newsvendor ordering through experiments.Findings indicated that openness can predict the ordering behavior at both individuals and group levels well.At the individual level,participants high in openness aren’t susceptible to anchoring cues, the other four kinds of personality characteristics are insigni?cantly associated with the anchoring bias;at the group level,the average openness score of a team and the proportion of relatively higher openness members are negatively related with anchoring bias.Comparing the results of individual and group level,we ?nd that the anchor inclination of group are signi?cantly smaller than that of individual, but group decision making is not better than individual decision-making.These results may help managers recruit employees,construct excellent decision teams and reduce decision bias.
