ChatGPT makes homework polished, but human thinking keeps it original
Bocconi University and OpenAI just ran a randomized trial on over 1,000 undergraduates and found that ChatGPT (GPT-4o) boosted rubric scores by nearly a full point on a five-point scale, making student work look expert-level. However, only critical-thinking exercises drove unique, outside-the-box ideas. AI polishes the answers, but human reasoning supplies the spark—meaning assignments must evolve to reward originality rather than tidy execution.
