Researchers Warn That RLHF Preference Data Encodes the Rater's State, Not Just the Output
Researchers introduce an audit framework showing RLHF preference data encodes the rater's condition during annotation, not just output quality — a structured confound that makes preference-data auditing a concrete axis of post-training rigor.
