论理性与一致性之间的关系
On the relation between rationality and consistency
摘要
We investigate whether the definition of economic rationality as choice consistency is correlated with decision-making ability. Guided by a theoretical framework, we demonstrate that documented positive correlations may be driven by confounding properties unrelated to consistency. To address this, in a novel experiment, we isolate consistency, measured by the Weak Axiom of Revealed Preference. We show that less sophisticated decision-makers often rely on simple rules and behave consistently, while more sophisticated ones consciously randomize, appearing inconsistent. These patterns determine ambiguous correlations, raising doubts about the choice of language that equates consistency with rationality in economics. Similar content being viewed by others
中文摘要
我们探究了将经济理性定义为选择一致性是否与决策能力相关。在理论框架的指导下，我们证明已有文献中记录的正相关关系可能由与一致性无关的混淆属性驱动。为此，在一项新颖的实验中，我们通过显示偏好弱公理来分离一致性。研究表明，决策能力较弱的个体往往依赖简单规则并表现出一致性行为，而决策能力较强的个体则会有意识地随机化选择，从而显得不一致。这些模式决定了模糊的相关性，对经济学中将一致性等同于理性的语言选择提出了质疑。
