Wicherts and Scholten criticized our study on statistical and psychometric grounds. We show that (i) using a continuous income variable, the interaction between income, and experimental manipulation remains reliable across our experiments; (ii) our results in the cognitive control task do not appear driven by ceiling effects; and (iii) our observed post-harvest improvement is robust to the presence of learning.
威彻斯和肖尔滕从统计学和心理测量学角度批评了我们的研究。我们表明：（一）使用连续的收入变量，收入与实验操作之间的相互作用在我们的所有实验中都保持可靠；（二）在认知控制任务中的结果似乎不是由上限效应驱动的；（三）我们观察到的收获后改善在存在学习的情况下也是稳健的。
