Magnitude effects in preference reversals: A meta-analysis
摘要
Preference reversal (PR) occurs when individuals reverse their preferences between safe and risky bets depending on the elicitation method (e.g., direct choice vs. certainty equivalence). Although prior research has rarely examined the influence of relative payoff ratios between bets on choice preferences and PR, this meta-analysis synthesizes data from 22 experiments or treatments across 13 studies, comprising 326 unique scenarios (N = 1,947). The mean effect sizes were close to zero, but substantial heterogeneity emerged across studies. Several idiosyncratic moderators—including probability and payoff structures and design features—appear to shape when choice preferences and PR are more likely to occur.
中文摘要
偏好反转（PR）现象指的是个体在安全赌注与风险赌注之间，依据不同的诱导方法（如直接选择与确定性等价）而逆转其偏好。尽管以往研究鲜少探讨赌注间相对支付比率对选择偏好及PR的影响，本元分析综合了13项研究中22个实验或处理组的数据，涵盖326个独特情境（N = 1,947）。平均效应量接近零，但研究间存在显著异质性。若干特定调节变量——包括概率与支付结构及设计特征——似乎决定了选择偏好与PR更可能发生的条件。
