LLM Judge Audits Flawed by Censored Rating Scale Analysis

A new research paper published on arXiv details a flaw in how Large Language Model (LLM) judges are audited, specifically concerning the use of difference-in-differences analysis on censored rating scales. The study demonstrates that this method can artificially inflate or manufacture an effect, even when no true preference difference exists between candidate responses. This manufactured effect arises from differential attenuation caused by the scale's bounds, which can be measured using the audit's own ratings. AI
