A study by Stanford Law School found that law professors preferred AI-generated answers to student questions over answers written by fellow professors, with AI winning 75% of head-to-head matchups. The study tested the ability of large language models to serve as effective tutors for contract law courses. The AI systems performed comparably to the best human instructor in the study, and professors flagged AI responses as pedagogically harmful only 3.5% of the time. The study's findings have implications for the use of AI in legal education.
