On the disruptiveness of interdisciplinary research and artificial intelligence for science
摘要
The relationship between interdisciplinarity and scientific disruption remains controversial, and the potential of artificial intelligence for science (AI4S) to advance science has yet to be effectively demonstrated. In this paper, we propose an LLM-assisted approach to identify interdisciplinary research (IDR) and AI use papers, and build a new dataset to study how IDR, interdisciplinary collaboration, and AI4S relate to disruptive science. Using Scopus records from 2014 to 2025, we analyze 1,154,30 papers published in six generalist journals with strong interdisciplinary coverage. We estimate the associations using fixed-effects models and quantile regressions. The validation results show that the LLM-based approach reliably identifies IDR and AI use papers. Empirically, IDR is positively associated with scientific disruption, whereas interdisciplinary collaboration is negatively associated on average. However, this relationship differs across the disruption distribution, with interdisciplinary collaboration negatively associated with disruption for low-disruption papers and positively associated for highly disruptive papers. AI4S shows a stronger positive association with disruption than IDR, but this association weakens at the upper tail of disruption.
