从逻辑上讲，集团成员对集团产出的责任不能超过100%，但声称对此负责的金额通常会超过100%。这种“过度主张”的部分原因是自我中心主义：作为团队的核心成员，人们更关注自己的贡献，而不是他人的贡献。因此，我们预测，过度索赔会随着团队规模的增加而增加，因为较大的团队会忽略更多来自其他人的贡献。在两项实地研究中，随着每篇论文的学术作者数量和每个研究小组的MBA学生数量的增加，参与者声称承担了更多的责任。正如我们的理论账户所预测的那样，当团队成员明确考虑他人的贡献时，这种过度主张的偏见会减少。两个直接操纵群体规模的实验重复了这些结果。较大团体的成员在考虑自己的贡献之前，最好先考虑其他成员的贡献。(SqucINFO数据库记录
Logically, group members cannot be responsible for more than 100% of the group's output, yet claims of responsibility routinely sum to more than 100%. This "over-claiming" occurs partly because of egocentrism: People focus on their own contributions, as focal members of the group, more than on others' contributions. Therefore, we predicted that over-claiming would increase with group size because larger groups leave more contributions from others to overlook. In 2 field studies, participants claimed more responsibility as the number of academic authors per article and the number of MBA students per study group increased. As predicted by our theoretical account, this over-claiming bias was reduced when group members considered others' contributions explicitly. Two experiments that directly manipulated group size replicated these results. Members of larger groups may be particularly well advised to consider other members' contributions before considering their own. (PsycINFO Database Record
