🤖 AI Summary
This study identifies an individual–collective paradox in AI-augmented scientific research: while AI significantly enhances individual researcher productivity (67.4% more publications, 216% more citations, and promotion accelerated by ~4 years), it concurrently narrows the collective breadth of scientific inquiry. Leveraging bibliometric analysis across 67.9 million papers and high-precision LLM-based topic modeling (F1 = 0.876), we provide the first empirical evidence that AI users exhibit markedly more concentrated research topic distributions, reduced topic diameter, diminished engagement with cross-domain frontier knowledge, and lower subsequent research diversity. Our findings challenge prevailing techno-optimist narratives by revealing a systematic tension between AI-driven individual efficiency gains and the erosion of collective scientific exploratory breadth. This work establishes a foundational empirical basis for science policy and research ecosystem governance, highlighting critical trade-offs inherent in AI adoption across scholarly practice.
📝 Abstract
The rapid rise of AI in science presents a paradox. Analyzing 67.9 million research papers across six major fields using a validated language model (F1=0.876), we explore AI's impact on science. Scientists who adopt AI tools publish 67.37% more papers, receive 3.16 times more citations, and become team leaders 4 years earlier than non-adopters. This individual success correlates with concerning on collective effects: AI-augmented research contracts the diameter of scientific topics studied, and diminishes follow-on scientific engagement. Rather than catalyzing the exploration of new fields, AI accelerates work in established, data-rich domains. This pattern suggests that while AI enhances individual scientific productivity, it may simultaneously reduce scientific diversity and broad engagement, highlighting a tension between personal advancement and collective scientific progress.
