A new study shared by Daniel Gross and Paul Novosad finds AI-assisted dissertation writing is most prevalent among students from non-English-speaking countries (40-50% for Iran, Korea, India, China vs 25% US) and at lower-ranked programs. Among US graduates, AI-written dissertations correlate with lower academic employment odds but higher industry placement. Only 26% of R1 institutions have dissertation-specific AI policies, and just 4.7% of dissertations acknowledge AI use by 2026.
