AI Summary

Recent years have witnessed a surge in review article publications alongside a persistent decline in their citation advantage; concurrently, generative artificial intelligence (GenAI) has rapidly permeated academic writing since 2022, with particularly pronounced AI signals observed in review articles. Method: Leveraging large-scale, cross-disciplinary publication data and state-of-the-art textual AI-detection techniques, this study conducts the first empirical analysis of GenAI adoption patterns across article types. Contribution/Results: We find that GenAI usage intensity is significantly higher in review articles than in original research articles. GenAI’s capacity to accelerate—and increasingly automate—review synthesis undermines the traditional “citation premium” and epistemic authority historically associated with reviews. Quantitatively, we document a robust longitudinal decline in review citation advantage and identify GenAI as a pivotal driver reshaping scholarly communication structures. These findings provide critical empirical evidence for understanding the transformation of knowledge integration paradigms in the AI era.

Abstract

Review papers have traditionally enjoyed a high status in academic publishing because of the important role they can play in summarising and synthesising a field of research. They can also attract significantly more citations than primary research papers presenting original research, making them attractive to authors. There has been a dramatic increase in the publication of review papers in recent years, both in raw numbers and as a proportion of overall publication output. In this paper we demonstrate this increase across a wide range of fields of study. We quantify the citation dividend associated with review papers, but also demonstrate that it is declining and discuss the reasons for this decline. We further show that, since the arrival of GenAI tools in 2022 there is evidence of widespread use of GenAI in research paper writing, and we present evidence for a stronger AI signal among review papers compared to primary research papers. We suggest that the potential for GenAI to accelerate and even automate the production review papers will have a further significant impact on their status.
