我们测量了来自美国上中西部三个相关人群的样本中的其他相关行为：大学生，来自大学周围社区的非学生成年人，以及居住培训计划中的成年实习卡车司机。使用典型的实验经济学招募程序，使前两组基本上是自我选择的。由于背景大大降低了参与的机会成本，91%的成年受训者参加了征集，在这个样本中几乎没有留下自我选择的余地。我们发现，在自我选择的成年人和成人学员之间的其他方面的偏好没有差异，这表明选择是不太可能偏见的非学生成人受试者之间的其他方面的偏好的患病率推断。我们的数据也拒绝了更具体的假设，即寻求认可的受试者是最有可能选择进入实验的人。最后，我们观察到自我选择的大学生和自我选择的成年人之间有很大的差异：学生表现出相当少的亲社会。
We measure the other-regarding behavior in samples from three related populations in the upper Midwest of the United States: college students, non-student adults from the community surrounding the college, and adult trainee truckers in a residential training program. The use of typical experimental economics recruitment procedures made the first two groups substantially self-selected. Because the context reduced the opportunity cost of participating dramatically, 91 % of the adult trainees solicited participated, leaving little scope for self-selection in this sample. We find no differences in the elicited other-regarding preferences between the self-selected adults and the adult trainees, suggesting that selection is unlikely to bias inferences about the prevalence of other-regarding preferences among non-student adult subjects. Our data also reject the more specific hypothesis that approval-seeking subjects are the ones most likely to select into experiments. Finally, we observe a large difference between self-selected college students and self-selected adults: the students appear considerably less pro-social.
