AI decision interfaces show significant language bias, study finds

A new study published on arXiv reveals significant language disparities in the performance of typed decision interfaces, which are used in AI systems to determine whether to automatically classify an item or pass it to a human. When tested with a confidence threshold of 0.9, these interfaces consistently classified requests in English more often than in any other language, even when the requests were answered correctly in both languages. This coverage gap persisted across multiple vendors and was not detected by standard calibration metrics on one interface. Translating inputs into English nearly eliminated the gap, suggesting that language bias is a critical factor in the equitable deployment of AI decision-making tools. AI

IMPACT Highlights the need for multilingual fairness in AI systems, potentially impacting global deployment and accessibility.

    One Confidence Threshold, Unequal Coverage: Language Gaps in Typed Decision Interfaces and How Translating Inputs Reduces Them

    arXiv:2610.37688v1 Announce Type: cross Abstract: Deployed classifiers often act on a prediction only when its confidence clears a threshold and pass the rest to a person. We ask whether one threshold serves all languages equally on typed decision interfaces, APIs that return a p…
