西点军校将学员随机分配到社会群体，这提供了一个难得的机会来强调许多研究中发现的对社会群体效应的潜在误导性估计。在人力资本生产的同期组效应的估计通常是积极的和显着的，但是，在这项研究中的证据表明，发生共同的一组可能占这种相关性。解决这些偏见的模型提供了很少的证据表明，在学习成绩的群体效应，虽然有证据表明，在选择的结果，如学术专业的选择和决定留在军队的群体影响。
The random assignment of cadets to social groups at West Point provides a rare opportunity to highlight potentially misleading estimates of social group effects found in many studies. Estimates of contemporaneous group effects in human capital production are typically positive and significant; however, evidence in this study suggests that occurrences common to a group may account for much of this correlation. Models that address these biases provide little evidence of group effects in academic performance, although there is evidence of group influences in choice outcomes such as the selection of academic major and the decision to remain in the Army.
