Using AI makes your work better. But are you, the person using it, actually getting better? Title: Does better work always mean better workers? URL: Google Research ran a three-month field experiment with 133 patent attorneys to test how AI assistance affects both the quality of work and the durability of professional judgment. Highlight 1 📈 Everyone's work improves with AI Patent drafting with AI access improved quality by 0.34 SD after 10 days and 0.38 SD after 90 days. Junior attorneys also drafted 18 minutes faster than the control group. Highlight 2 ⚖️ Take the AI away, and experience matters At day 90, attorneys reviewed patent claims without AI. Senior attorneys (7+ years) improved by a striking 0.45 SD. Junior attorneys showed no average improvement at all, instead splitting into stronger and weaker performers. Highlight 3 🔍 Fixing vs. rephrasing Junior attorneys worked sequentially from the top, spending time on surface-level wording and rarely fixing the substantive flaws they identified. Senior attorneys used AI as a logic auditor and rebuilt claims from the ground up. Better output and better workers aren't the same thing. #AIWorkforce# #KnowledgeWork#
