When Algorithms Don’t Know What They Don’t Know: Fairness in Uncertain Systems
![Efforts to minimize false negatives, while initially effective, demonstrate a tendency toward instability and overshoot across decision rounds-a phenomenon exacerbated by interaction proxy bias, which causes diverging trajectories and underscores the inherent limitations of addressing uncertainty when foundational proxies are structurally compromised, as reflected in the observed [latex]\Delta\text{FNR}[/latex] fluctuations.](https://arxiv.org/html/2604.21711v1/x12.png)
New research explores how acknowledging and quantifying uncertainty in sequential decision-making-particularly when data is biased-can lead to more equitable and effective AI systems.
