决策中的无意义反馈信息寻求

The Seeking for Meaningless Feedback in the Decision Making

摘要: 决策者在进行决策的过程中会倾向于去收集信息。有时候这种倾向确实可以帮到他们，但寻求无意义的信息可能会提高决策的难度和浪费决策者的时间，甚至可能降低决策的质量。本研究用三个实验验证了人们在决策时有寻求无意义反馈信息的倾向。实验1、2、3分别使用了三种不同的实验任务验证了这个现象的稳定性，三个实验各招募了60名中国本科生作为被试。三个实验的配对样本t检验的结果都达到了显著性水平(p < 0.05)，结果显示选择接受无意义反馈信息的被试要显著多于不接受无意义反馈信息的被试。这个现象提醒我们在进行决策时要意识到自己有这个倾向，要注意所要收集的信息的质量以避免因为收集无意义的信息而浪费时间。

Abstract: The decision-maker tends to collect the information in the process of deciding. Sometimes this tendency does help them, but seeking meaningless information may increase the difficulty of de-ciding and waste the time of decision-makers, and even lower the quality of decisions. The current study conducted three experiments to verify that people tend to seek meaningless feedback in the process of making a decision. Experiments 1, 2, and 3 respectively used three different tasks to verify the stability of this phenomenon, and 60 Chinese undergraduates were respectively recruited as subjects in each experiment. The result of paired-samples T-test in experiments 1, 2, and 3 was all significant (p < 0.05), which showed that the number of subjects who chose to receive the meaningless feedback is significantly more than the number of subjects who rejected to receive the meaningless feedback. This phenomenon reminded us that when we are making the decision, we should realize we have this tendency and pay attention to the quality of the information we are going to collect and avoid wasting time on meaningless information.
