Wu et al. (2019) proposed the disruption index (DI1) as a bibliometric indicator that measures disruptive and consolidating research. Leibel and Bornmann (2024) recently published a literature overview on the disruption index research in Scientometrics. In this letter to the editor, we point out that the method of calculating the DI1 score of a focal paper contains a logical impact measurement error that leads to a meaningful reduction of the score. We explain why this is problematic and propose a correction of the formula.

翻译：Wu等（2019）提出了破坏性指数（DI1）作为衡量颠覆性与整合性研究的文献计量指标。Leibel与Bornmann（2024）近期在《科学计量学》期刊上发表了关于破坏性指数研究的文献综述。在这篇致编辑的信函中，我们指出当前对焦点论文DI1得分的计算方法存在逻辑性影响测度误差，该误差会导致得分出现显著降低。我们阐释了此问题的危害性，并提出了公式修正方案。
