摘要

我们重新考虑一个最广泛研究的行为偏差：锚定效应。我们估计，本文献中的研究设计，包括重复性研究，通常无法达到超过30%的统计功效。这项研究重复了一项锚定研究，该研究报告了参与者出价增加31%的效应大小。在重复实验中，我们将设计的统计能力从46%提高到96%，将统计显著结果的平均夸张程度降低了七倍。我们的复制结果拒绝了原始估计效应的大小。我们发现估计效果为3.4% （95% CI[−3.4%,10%]）。

Underpowered studies and exaggerated effects: A replication and re-evaluation of the magnitude of anchoring effects

We reconsider one of the most widely studied behavioral biases: anchoring effects. We estimate that study designs in this literature, including replication studies, routinely fail to achieve statistical power of more than 30%. This study replicates an anchoring study that reported an effect size of a 31% increase in participants' bids. In the replication, we increased the design's statistical power from 46% to 96%, reducing the average exaggeration of a statistically significant result by a factor of seven. Our replication results reject the size of the original estimated effects. We find an estimated effect of 3.4% (95% CI [−3.4%, 10%]).

期刊介绍： Published since 1962, (formerly Western Economic Journal), EI is widely regarded as one of the top scholarly journals in its field. Besides containing research on all economics topic areas, a principal objective is to make each article understandable to economists who are not necessarily specialists in the article topic area. Nine Nobel laureates are among EI long list of prestigious authors.
