Ballot Position, Choice Fatigue, and Voter Behaviour
利用选民因地方议题数量不同而面临同一竞选在不同选票位置的自然实验，研究发现选择疲劳显著增加弃权或依赖决策捷径（如投给现状或首位候选人）的倾向；若无选择疲劳，弃权率将下降8%，6%的提案结果会由失败转为通过。
In this article, we examine the effect of “choice fatigue” on decision making. We exploit a natural experiment in which voters face the same contest at different ballot positions due to differences in the number of local issues on their ballot. Facing more decisions before a given contest significantly increases the tendency to abstain or rely on decision shortcuts, such as voting for the status quo or the first-listed candidate. We estimate that, without choice fatigue, abstentions would decrease by 8%, and 6% of the propositions in our data set would have passed rather than failed.
