通过两个实验,探讨了不同性质问题下的偏好逆转现象.实验一结果发现,在两种不同的决策方式下,在两类性质的问题上都出现了偏好逆转现象;实验二在控制了决策方式的情况下发现,仅在个体问题上存在偏好逆转现象,而群体问题上并没有出现偏好逆转现象.研究结果说明,决策方式和问题性质可能都会影响人们的决策偏向. Through two experiments, we discuss the phenomenon of preference reversal under different nature problems.Experimental results show that under the two different decision-making methods, preference reversal occurs on both types of problems; We found that there is a preference reversal phenomenon only on the individual problem, but there is no phenomenon of preference reversal on the group problem.The results show that the decision-making methods and the nature of the problem may affect people’s decision-making bias.
