论文摘要
我们测试当他们无法单独确定其能力，行动和参数对输出的影响的影响时，对自己能力的不正确信念的个人如何学习外部参数（“基本”）。海德斯等人。 （2018年）认为，随着他们对基本基本的信念变得越来越少，使他们过分自信的人变得更加恶化，从而导致他们采取更糟的行动。在我们的实验中，受试者进行了错误标记的测试，我们衡量他们如何随着时间的推移了解标记的准确性。过分自信的主题付出了较少的努力，正如他们所学到的那样，他们对标记准确性的信念变得更糟。在实验中，对正确答案的比例的信念下降了0.05。我们发现对自信的受试者没有影响。
We test how individuals with incorrect beliefs about their ability learn about an external parameter (`fundamental') when they cannot separately identify the effects of their ability, actions, and the parameter on their output. Heidhues et al. (2018) argue that learning makes overconfident individuals worse off as their beliefs about the fundamental get less accurate, causing them to take worse actions. In our experiment, subjects take incorrectly-marked tests, and we measure how they learn about the marker's accuracy over time. Overconfident subjects put in less effort, and their beliefs about the marker's accuracy got worse, as they learnt. Beliefs about the proportion of correct answers marked as correct fell by 0.05 over the experiment. We find no effect in underconfident subjects.
