Imprecision as an Account of the Preference Reversal Phenomenon
通过实验测量个体决策中的不精确性，并检验其能否解释两种相反形式的偏好反转，其中一种此前未见报道。结果表明，成功的描述性选择理论需要纳入决策中的不精确性。
Many individuals' choices and valuations involve a degree of uncertainty/imprecision. This paper reports an experiment designed to obtain some measure of imprecision and to examine the extent to which it can explain preference reversals of two opposite forms, one of which appears not to have been reported previously. The model of imprecision we examine not only predicts both patterns but also provides an account of earlier results that are otherwise not well explained. The results suggest that any successful descriptive theory of choice and valuation will need to allow in some way for the imprecision surrounding people's decisions.
