When Fairness Metrics Disagree: Evaluating the Reliability of Demographic Fairness Assessment in Machine Learning
arXiv:2604.15038v2 Announce Type: replace Abstract: The evaluation of fairness in machine learning systems has become a central concern in high-stakes applications, including biometric recognition, healthcare decision-making, and automated risk assessment. Existing approaches typically rely on a small number of fairness metrics to assess model behaviour across group partitions, implicitly assuming that these metrics provide consistent and reliable conclusions. However, different fairness metrics capture distinct statistical properties of model performance and may therefore produce conflicting
The proliferation of AI systems in sensitive applications necessitates robust fairness evaluations, making the reliability of assessment metrics a critical current concern.
A strategic reader needs to understand the limitations of current AI fairness evaluation, as inaccurate assessments can lead to biased outcomes and regulatory backlash.
The understanding of AI fairness metrics shifts from an assumption of consistency to an acknowledgement of potential disagreement and the need for more nuanced, context-aware evaluation.
