en.Wedoany.com Reported - A new study from Stanford Law School shows that law professors, in a blind review, preferred AI-generated answers to legal questions over those written by professors themselves, at a rate of 75%. The research team had two AI platforms, Google's Gemini 2.5 Pro and NotebookLM, answer 40 first-year contract law questions, which were jointly drafted by professors from 14 U.S. law schools and represented typical questions students often ask.
Professors conducted a blind comparison of short answers, and the results showed that AI-generated answers were considered more beneficial for student learning. Julian Nyarko, the study's lead author and a Stanford law professor, said the research team was surprised by the magnitude of the results, noting that the questions were not simple enough to have obvious answers. The study comes amid debates in law schools and the legal profession about integrating AI into teaching and practice. Previous research has shown that AI can pass the bar exam, earn A+ grades in law school, and effectively assess U.S. law school exams.
An increasing number of U.S. law schools require first-year students to receive AI instruction, but approaches vary. Berkeley Law School recently adopted a policy strictly limiting how students may use AI in academic work. This new study on tutoring suggests that AI can bring benefits to teaching. The research shows that law students can use AI to obtain answers on demand with reliable results, without relying on peers or occasionally emailing instructors.
Importantly, less than 4% of AI-generated answers were marked by reviewers as "harmful" to student learning, compared to 12% for professor-written answers. Alejandro Salinas, a Stanford researcher and co-author of the study, noted that AI tutors can provide high-quality, on-demand support, supplement classroom teaching, and potentially expand access to expert guidance.
