我们调查了老年人是否比年轻人更容易违反理性决策的基本属性，即传递偏好公理。我们的实验包括两组，老年人（60-75岁; 21名参与者）和年轻人（18-30岁; 20名参与者）。我们使用贝叶斯模型的选择，以调查是否更好地描述个人通过（传递）弱序为基础的决策策略或（可能是不传递的）词典半序决策策略。我们发现弱证据的假设，老年人违反传递性在更高的利率比年轻的成年人。与此同时，分层贝叶斯分析表明，在这项研究中，决策策略在个体之间的分布对于老年人和年轻人来说是相似的。
We investigated whether older adults are more likely than younger adults to violate a foundational property of rational decision making, the axiom of transitive preference. Our experiment consisted of two groups, older (ages 60-75; 21 participants) and younger (ages 18-30; 20 participants) adults. We used Bayesian model selection to investigate whether individuals were better described via (transitive) weak order-based decision strategies or (possibly intransitive) lexicographic semiorder decision strategies. We found weak evidence for the hypothesis that older adults violate transitivity at a higher rate than younger adults. At the same time, a hierarchical Bayesian analysis suggests that, in this study, the distribution of decision strategies across individuals is similar for both older and younger adults.
