The present study sought to evaluate the reproducibility of prominent findings stated by Fehr et al. in their developmental resource allocation experiment "Egalitarianism in Young Children", published in 2008. The experiment involved children making decisions about distributing sweets between themselves and either an in‐group or an out‐group recipient. Fehr et al. found that (1) inequity aversion develops with age; (2) 3‐ to 4‐year‐old children are inclined toward self‐advantageous allocations, whereas 7‐ to 8‐year‐olds distribute sweets more evenly in divisions, and (3) the influence of group status increases as children age. The original article stated that 229 Swiss school students aged 3 to 8 years (102 boys, 127 girls) participated in the study. However, no further demographics were reported. In our attempts to reproduce Fehr et al.'s original analyses and reanalyse the raw dataset, we found that one of the key variables was miscoded. After rectifying the miscoded variable, the reproduction results revealed only one ambiguously irreproducible result regarding a group status main effect in the sharing mini‐game—with three other tests exhibiting either strong reproducibility or ambiguous reproducibility. Reanalysis results indicated that Fehr et al.'s conclusions are robust when tested with alternative analytical tests.Highlights We evaluated the reproducibility of Fehr et al.'s (2008) highly cited developmental resource allocation findings. After identifying an inversely coded variable, we found all tests—bar one probit regression not related to major findings—to be reproducible. Reanalysis confirmed the robustness of Fehr et al.'s conclusions when using alternate analytical methods. Fehr et al.'s developmental resource allocation findings are reproducible and have theoretical implications for understanding inequity aversion and group status effects on resource allocation decisions in young children.

验证报告：幼儿的平等主义

本研究旨在评估 Fehr 等人所述的重要发现的可重复性。在他们的发展性资源分配实验“幼儿的平等主义”中，发表于 2008 年。该实验让孩子们决定如何在自己和群体内或群体外的接受者之间分配糖果。菲尔等人。发现（1）不平等厌恶随着年龄的增长而发展； （2）3至4岁的儿童倾向于对自己有利的分配，而7至8岁的儿童则更均匀地分配糖果；（3）群体地位的影响随着儿童年龄的增长而增加。原文称，229名3至8岁的瑞士学校学生（102名男生，127名女生）参与了这项研究。然而，没有报告进一步的人口统计数据。在我们尝试重现 Fehr 等人的原始分析并重新分析原始数据集时，我们发现关键变量之一被错误编码。纠正错误编码的变量后，再现结果仅显示了一个关于共享小游戏中群体状态主效应的模糊不可再现结果，而其他三个测试则表现出强再现性或模糊再现性。再分析结果表明，Fehr 等人的结论在使用替代分析测试进行测试时是稳健的。亮点 我们评估了 Fehr 等人 (2008) 被高度引用的发展资源分配研究结果的可重复性。 在识别出反向编码变量后，我们发现所有测试（除了与主要发现无关的概率回归）都是可重复的。再分析证实了 Fehr 等人在使用替代分析方法时得出的结论的稳健性。 Fehr 等人的发展资源分配研究结果是可重复的，对于理解不平等厌恶和群体地位对幼儿资源分配决策的影响具有理论意义。
