系统地使用网络搜索工具来浏览和评估建议的做法十分普遍。这些工具对于用户真正受益于网上提供的大量选择可能至关重要。然而，最近的一项研究表明，更多的搜索选项会引发过度搜索，并导致劣质决策（即，越多意味着越差的效果; Wu & Chiou，2009）。考虑到那些有动机做出准确选择的人（准确性激励）倾向于进行更广泛和更详尽的搜索，实验1研究了准确性激励如何影响搜索过程。研究结果表明，准确性激励导致过度搜索和较差的选择。此外，搜索率，过度搜索的指标，中介的负面影响的准确性激励的选择质量。实验2探讨认知需要（NFC）在越是手段越差效应中的作用。高NFC参与者表现出过度搜索的倾向增加，表现出比低NFC参与者更差的选择性。现有研究表明，在线搜索者的准确性激励可能是过度搜索的决定因素，高NFC的在线搜索者可能更容易受到过度搜索的负面影响。版权所有（C）2015约翰威利父子有限公司
The systematic use of Web search tools to browse and evaluate recommendations is widespread. Such tools may be crucial for users to truly benefit from the enormous selection of options available online. However, a recent study demonstrated that a greater number of search options triggered excessive searching and led to inferior decisions (i.e., the more-means-worse effect; Wu & Chiou, 2009). Given that individuals who are motivated to make accurate choices (the accuracy incentive) tend to engage in broader and more exhaustive searches, Experiment 1 examined how the accuracy incentive influenced the search process. The findings indicated that the accuracy incentive led to excessive searching and poorer choices. Moreover, the search ratio, an indicator of excessive searching, mediated the negative effect of the accuracy incentive on choice quality. Experiment 2 investigated the role of the need for cognition (NFC) in the more-means-worse effect. High-NFC participants demonstrated an increased tendency toward excessive searching and exhibited poorer selectivity than did low-NFC participants. The current research indicated that the accuracy incentive of online searchers may serve as a determinant of excessive searching and that online searchers characterized by high NFC may be more vulnerable to the negative effects of excessive searching.
