Cohn et al. (2019) designed the field experiment about the lost wallets across 40 countries to examine whether people attempt to contact the owners to return the 17,000 wallets. We discussed the design flaw in their experimental settings by reanalyzing the relationship between the rates of wallet return, in the Cohn et al. (2019)’s data, and the percentage of the Internet penetration (over population) as an upper bound of proportion email users. We found that countries with limited access to email have a lower rate of wallets’ return after controlling other factors. Furthermore, we revisited the Abeler et al. (2019)’s aggregated data to study whether the dishonest behaviors in the laboratory could predict the actual honesty behavior or not. It turns out that what happens in the lab makes no sense to our reality. This comment contributes to the extant literature about an experimental designation for honesty studies.

电子邮件与公民诚实感如何相关？对Cohn等人的评论。（2019）

Cohn等。（2019）设计了一个针对40个国家/地区丢失的钱包的实地实验，以检查人们是否试图联系所有者以退还17,000个钱包。在Cohn等人的文章中，我们通过重新分析钱包返还率之间的关系，讨论了实验设置中的设计缺陷。（2019）的数据，以及互联网普及率（人口总数）占电子邮件用户比例上限的百分比。我们发现，在控制其他因素之后，电子邮件访问受限的国家/地区的钱包退货率较低。此外，我们重新审视了Abeler等人。（2019）的汇总数据用于研究实验室中的不诚实行为是否可以预测实际的诚实行为。事实证明，实验室中发生的一切对我们的现实毫无意义。
