Mentored Risk in Research Training

Doctoral supervisors pass their tolerance for risky projects to their PhD students, producing a durable cultural transmission that persists after students leave the lab. The effect strengthens with frequent supervisor–student interaction and weakens when students have external co‑mentors. — If doctoral mentorship systematically shapes risk preferences, policy levers to foster high‑risk, high‑reward science include reforming doctoral training, promoting co‑mentorship, and aligning evaluation incentives at the lab level — not only changing grant rules.
