First-Person Fairness in Chatbots

links:none on file
slides:none on file

Defines first-person fairness as fairness toward the individual user and gives a repeatable pipeline: use public chat corpora (LMSYS, WildChat), a language-model grader to label millions of chats, and crowdsource checks (LM–human correlation ≈ 0.86). Measured harmful stereotypes and quality gaps by replaying prompts with different names as demographic proxies; earlier pre‑RL models show biases up to ~5% in some tasks (stories highest), while post‑training reinforcement learning cuts those biases to typically under 1%, demonstrating a scalable, effective mitigation.
