New benchmark FairCoder probes LLM bias in high-stakes decisions

Researchers have developed FairCoder, a new benchmark designed to identify biases in large language models (LLMs) when they are used for high-stakes decisions like hiring or admissions. This benchmark frames decision-making tasks as coding problems, allowing for the systematic probing of implicit biases across various domains and fairness definitions. To address situations where LLMs might refuse requests, the study also introduces FairScore, a metric that evaluates both refusal behavior and the diversity of group outcomes. Initial experiments using a 1,000-sample dataset on advanced LLMs have revealed previously unrecognized bias patterns, such as favoring applicants from wealthier backgrounds in college admissions, highlighting the risks associated with deploying LLMs in critical decision-making roles.

    FairCoder: Probing LLM Bias in High-Stakes Decision Making via Coding Tasks

    arXiv:2501.05396v3 Announce Type: replace Abstract: Large language models (LLMs) are increasingly used in high-stakes decisions such as hiring and college admissions, making their social bias a critical concern. While LLMs are trained to refuse explicitly biased requests, bias ca…
