In a blind study published June 1, 2026, by Stanford Law Professor Julian Nyarko and co-authors, law professors preferred AI-generated answers to student questions over answers written by their professional peers roughly three times out of four. The study enrolled 16 contracts law professors at 14 top U.S. law schools, each writing office-hours-style answers to 40 representative student questions, which were then posed to AI systems, primarily Google's Gemini 2.5 Pro and Google's NotebookLM. Nearly 3,000 pairwise comparisons were assessed blind, with AI winning 75% of the head-to-head matchups. Professors rated AI responses as potentially harmful in just 3.5% of cases, while peer-written answers were flagged at a rate of 12%, with one instructor's answers judged as harmful in nearly 40% of cases. The research comes as U.S. law schools set AI policy, including the University of Chicago Law School's plan to ban laptops from all first-year core courses.
