再探究不确定状态下违背“确定事件”原则的原因?

确定事件原则是规范决策理论的基本原则之一。本研究通过选取具有不同文化背景的被试、构建和修改一系列问题情境来考察违背确定事件原则的原因。结果表明，在双重理由的分离情境中，确定事件原则被违背了；而在单一理由的分离情境中，确定事件原则得以遵循。实验结果支持“基于理由的假设”而不支持“思维惰性假设”。文章最后讨论了本研究的理论及现实意义。

Re-examining Reasons Leading to Violations of Savage's Sure-Thing Principle Under Uncertainty

Leonard J.Savage's sure-thing principle(1954),a key assumption of the consequentialist conception of decision making under uncertainty,states that if some option x is preferred to y given some other Event A occurs,and if option x is preferred to y given this event A does not occur,then x should be preferred to y even when the outcome of A is unknown.Much theoretical and experimental research has examined whether the sure-thing principle was violated in a variety of situations.But,not as much focus has been ...
