This study focuses on a recently introduced type of indicator measuringdisruptiveness in science. Disruptive research diverges from current lines ofresearch by opening up new lines. In the current study, we included theinitially proposed indicator of this new type (Wu, Wang, & Evans, 2019) andseveral variants with DI1: DI5, DI1n, DI5n, and DEP. Since indicators shouldmeasure what they propose to measure, we investigated the convergent validityof the indicators. We used a list of milestone papers, selected and publishedby editors of Physical Review Letters, and investigated whether this human(experts - based list is related to values of the several disruption indicatorsvariants and - if so - which variants show the highest correlation with expertjudgements. We used bivariate statistics, multiple regression models, and(coarsened) exact matching (CEM) to investigate the convergent validity of theindicators. The results show that the indicators correlate differently with themilestone paper assignments by the editors. It is not the initially proposeddisruption index that performed best (DI1), but the variant DI5 which has beenintroduced by Bornmann, Devarakonda, Tekles, and Chacko (2019). In the CEManalysis of this study, the DEP variant - introduced by Bu, Waltman, and Huang(2019) - also showed favorable results.
