Take It or Leave It: How Choosing versus Rejecting Alternatives Affects Information Processing
研究发现，与选择任务相比，拒绝任务会促使人们更依赖深思熟虑的信息处理，从而减少决策偏差，提高决策质量。
People can make decisions by choosing or by rejecting alternatives. This research shows that changing a task from choice to rejection makes people more likely to rely on deliberative processing, what we label the task-type effect. To demonstrate this effect, we use a set of established decision biases that can be attenuated under deliberative processing. We show that changing a task from choice to rejection makes people express more consistent preferences between safe and risky options in the Asian disease problem (study 1A) and in financial decision making (study 1B), even with real monetary consequences (study 1C). Further, switching a task from choice to rejection increases the quality of consideration sets in the context of hotel reviews (study 2) and leads to more rational decisions in the context of cell phone plan selection (study 3). Studies 4 and 5 tap into the process underlying the effect of task type. We demonstrate that a rejection task produces decisions similar to those observed in a choice task when decision makers are cognitively depleted (study 4) or encouraged to rely on their feelings (study 5). The findings provide insight into the effect of task type on deliberation and decision outcomes.
