Randomized trial finds AI and critical-thinking training offer complementary gains
A randomized experiment with more than 1,000 Bocconi University students found that GPT-4o access improved rubric scores and coherence, while causal-reasoning training increased idea variety; students receiving both retained both kinds of benefit.

Why it moved the index
The randomized design and human grading provide practical evidence that targeted reasoning instruction can preserve a distinct human advantage in originality while students use a capable model. The result is limited to one university assignment, and OpenAI collaborated on and reported the study, so it supports a moderate rather than broad resilience claim.
