Stanford study warns AI use may weaken students’ learning and critical thinking

A Stanford University review of 52 studies on AI in education highlights a key concern: students may complete assignments faster using generative AI without developing independent understanding. The November 2026 review found that AI shows greater promise when used to explain concepts, provide feedback and support practice rather than replace student thinking. While AI can improve learning experiences and save teachers’ time, researchers say evidence of lasting improvements in academic performance remains insufficient.
