Generative AI Reduced Study Time and Learning Outcomes in Math, Large-Scale Study Finds

Jul 14, 2026

A ten-year study analyzing 3.2 million learning interactions found that, following the release of ChatGPT, college students spent 26.9% less time on math problems susceptible to AI assistance, with a 25% decline in retention on proctored assessments. The effect was not observed under proctoring, suggesting the reduction in time was not due to increased efficiency. The authors interpret these findings as evidence of 'cognitive surrender' with implications for education and AI policy.

Why it matters: This study provides some of the first large-scale behavioral evidence that generative AI is changing how students study and what they learn, raising important questions for educational assessment and AI regulation.
