Noisy text inflates LLM bias judgments, study finds

A new study published on arXiv investigates the impact of noisy text on large language models used for bias measurement. Researchers found that common text imperfections like typos and informal spelling can disproportionately inflate bias judgments, turning neutral text into biased text at a significantly higher rate than the reverse. This overestimation of bias, particularly in critical categories, suggests that current LLM-as-a-judge methods may be unreliable when applied to real-world, imperfect text. AI

IMPACT Suggests current LLM bias measurement tools may be unreliable with real-world text, potentially impacting fairness evaluations.

    When Noise Fabricates Bias: The Fragility of LLM-as-a-Judge Bias Measurement under Noisy Text

    arXiv:2609.11067v1 Announce Type: new Abstract: Large language models are increasingly used as judges to measure social bias in text, yet the passages they judge are often noisy, containing typos, informal spelling, and broken punctuation. The consequences of such surface noise f…
