巴托比专栏——决策疲劳的风险
Why breaks are actually good for productivity
为什么休息实际有助于提高工作效率

But it may be pretty good advice for any manager or worker, minus the calories.
但对于所有管理者或员工来说，这句话都可能是一个很好的建议，抛开卡路里这部分。
The longer the shift, the less effective the employee may become.
一个轮班的时间越长，员工的工作效率可能就越低。
In a new paper for Royal Society Open Finance, “Quantifying the cost of decision fatigue: suboptimal risk decisions in finance”, Tobias Baer and Simone Schnall examine the credit decisions of loan officers at a leading bank over the course of their working day.
托拜厄斯·贝尔和西蒙妮·施纳尔在为皇家学会开放金融撰写的一篇题为“量化决策疲劳的成本：金融中的次优风险决策”的新论文中，研究了一家主要银行的信贷员在工作期间的信贷决策。
The academics write that decision fatigue “typically involves a tendency to revert to the ‘default’ option, namely whatever choice involves relatively little mental effort”.
这两位学者写道，决策疲劳“通常涉及一种回归‘默认’选项的倾向，即任何需要相对较少脑力劳动的选择”。
In other words, as you become tired, you get mentally lazy.
换句话说，当你累了，你就会在精神上变得懒惰。
The study looked at proposals to restructure loans, with each credit officer analysing 46 requests per day.
这项研究考察了重组贷款的申请，每位信贷官员每天分析46份申请。
The approval rate was around 40%, so the default decision was rejection.
通过率在40%左右，默认的决策是驳回。
Officers tended to start work between 8am and 10am, took lunch between 1pm and 3pm, and tended to leave at 6pm.
信贷官员们通常在早上8点到10点上班，下午1点到3点吃午饭，在下午6点下班。
The researchers found that the approval rate declined significantly between 11am and 2pm, as lunch approached, then picked up again after 3pm before declining in the last two hours of work.
研究人员发现，随着午餐时间临近，即上午11点至下午2点之间，通过率显著下降，然后在下午3点之后开始回升，在工作的最后两个小时再次下降。
The applications were distributed to credit officers by the bank’s automated system, so they were in effect allocated randomly.
这些申请是由银行的自动化系统分配给信贷员的，因此它们实际上是随机的。
There is no sign that the loans assessed at lunchtime were of a different quality from those in the rest of the day.
没有迹象能够表明，午餐时间评估的贷款与当天其他时间评估的贷款质量不同。
What makes this study ingenious is that the authors were able to see whether or not the loans were subsequently paid back.
这项研究的独创性之处在于，作者能够看到这些贷款后来是否被偿还。
They found that rejecting a restructuring request made it less likely that the loan would be repaid.
他们发现，驳回重组贷款请求会降低贷款得到偿还的可能性。
So they calculated that decision fatigue, by causing more rejections, actually cost the bank money; around $500,000 over the course of a single month.
因此，他们推算出，决策疲劳，作为驳回增加的原因，实际上给银行造成了损失；大约每月50万美元。
Similar patterns have been seen in other situations.
在其他职位中也有类似的状况。
A much-cited study of Israeli judges found they were less likely to grant parole as lunch approached, but became more lenient once their stomachs were full again.
一项被广泛引用的关于以色列法官的研究发现，在临近午餐时间时，他们不太可能批准假释，但一旦他们的胃被再次填饱，他们就会变得更加宽容。

And the study of credit officers indicates that companies should look for ways to protect workers against decision fatigue.
