🤖 AI Summary
The opaque pathways through which scientific research informs intergovernmental organization (IGO) policy hinder evidence-informed global governance. This study addresses the lack of systematic understanding of scientists with demonstrable policy impact (PI-Scis) and their cross-disciplinary, transnational influence patterns.
Method: Leveraging a corpus of over 230,000 scholarly articles cited in IGO policy documents, we integrate bibliometrics, author name disambiguation, collaboration network modeling, and multi-source data linkage to identify and characterize PI-Scis.
Contribution/Results: We provide the first large-scale empirical characterization of PI-Scis’ structural properties, temporal evolution, and the “publish-and-be-cited-in-policy” cumulative advantage mechanism. PI-Scis are highly concentrated within elite, interconnected networks—serving as knowledge brokers in advisory bodies such as the IPCC. Disciplinary variation in influence concentration is pronounced, and knowledge diffusion across major IGOS exhibits strong synchronicity. These findings establish a foundational empirical basis and methodological framework for analyzing the global science–policy interface.
📝 Abstract
Intergovernmental organizations (IGOs) increasingly rely on scientific evidence, yet the pathways through which scientific research enters policy remain opaque. By linking 230,737 scientific papers cited in IGO policy documents (2015-2023) to their authors and collaboration networks, we identify a small group of policy-influential scientists (PI-Sci) who dominate this knowledge flow. These scientists form tightly interconnected, internationally spanning co-authorship networks and achieve policy citations shortly after publication, a distinctive feature of cumulative advantage at the science-policy interface. The concentration of influence varies by field: tightly clustered in established domains like climate modeling, and more dispersed in emerging areas like AI governance. Many PI-Sci serve on high-level advisory bodies (e.g., IPCC), and major IGOs frequently co-cite the same PI-Sci papers, indicating synchronized knowledge diffusion through shared expert networks. These findings reveal how network structure and elite brokerage shape the translation of research into global policy, highlighting opportunities to broaden the scope of knowledge that informs policy.
