本文使用“病理”社会科学的概念来考虑学校混合效应的概念，其中对知识的大量主张是基于数据中的非常小的差异。它描述了对同一组发现的各种貌似合理的替代解释，包括学校混合效应，但也包括测量和模型规范中的错误。结论是，相信学校混合效应很难维持，其他解释也同样可能。在这种情况下，基于这种效应的有效性，期望从工作中取得很多实际进展可能是“病态的”，并且与其他领域出现的那种消失的突破相比。
This paper uses the notion of ‘pathological’ social science, wherein large claims to knowledge are made on the basis of very small differences in the data, to consider the notion of the school mix effect. It describes a variety of plausible alternative explanations for the same sets of findings, including the school mix effect, but also errors in measurement and in the specification of the model. The conclusion is that belief in a school mix effect is difficult to sustain, and that the other explanations are just as probable. In these circumstances, it could be ‘pathological’ to expect much practical progress from work based on the validity of this effect, and the situation is compared to the kinds of vanishing breakthroughs occurring in other fields.
