SUMMARY - What Is Algorithmic Bias?
A hiring algorithm trained on historical employment data learns that successful candidates were predominantly male and begins filtering out women's resumes. A facial recognition system trained primarily on light-skinned faces fails to identify darker-skinned individuals, leading to wrongful arrests. A healthcare algorithm prioritizing patients for treatment uses cost as a proxy for need, systematically deprioritizing Black patients who historically had less spent on their care regardless of actual medical necessity.
