LLM evaluation pipeline shows identity bias amplification with full anonymization

A new study published on arXiv investigates identity bias within multi-agent Large Language Model (LLM) evaluation systems. Researchers found that partial anonymization of LLM components in the TRUST pipeline can mask significant identity-driven sycophancy, leading to misleading conclusions about bias. Only full-pipeline anonymization accurately reveals how homogeneous ensembles amplify bias and heterogeneous configurations mitigate it, highlighting the importance of proper anonymization for reliable LLM system validation.
