An analysis of 41 million scientific articles showed that artificial intelligence (AI) increases the individual impact of scientists, allowing them to publish more papers and succeed more often.[1] However, AI is narrowing the collective scientific inquiry, with AI papers covering 4.6% fewer topics than conventional studies.[1] AI-led research focuses on popular issues, creating "lonely crowds" with less interaction between articles and a less connected literature.[1][2] This effect arises from a feedback loop: popular topics attract large datasets, which facilitate AI and attract more scientists to the same questions.[1] The results indicate a concentration of research on narrow topics, which reduces the diversity and scope of science.[1][2] The scientific community sees these findings as a warning because science is a collective effort.[1]
