A Brown University economics professor, Roberto Serrano, suspected that students were using generative AI to cheat on exams. To test this, he replaced a take-home test with an in-person final, and the average score dropped by 50 percent.
This incident aligns with a survey of Princeton students where 29.9 percent admitted to using AI to cheat on at least one exam or assignment. The drastic score decline suggests that many students had been relying on AI rather than learning the material.
