today!! We ran a field experiment with ~1000 high school students & found: ✅ GenAI tutoring boosts practice perf ⚠️ But hinders human learning, hurting perf when AI access is removed 🛡️ Safeguards like hint-based help can offset this

Cool paper using brain imaging to track cognitive load while writing essays! As expected, people under-use their brain when using LLM assistance, but interestingly, they also struggle more when switching back to writing on their own -- AI assistance creates "cognitive debt"
