How do you measure AI bias?

Through disparate impact analysis—measuring whether outcomes differ significantly across protected groups. Common metrics include statistical parity (equal positive rates across groups), equal opportunity (equal true positive rates), and calibration (predicted probabilities reflect actual rates equally across groups). Each metric captures a different fairness dimension; choose the one most relevant to your context. Run bias audits at deployment and monitor continuously, since bias can emerge as data distributions shift.

AI Bias

Written by Max Zeshut

Systematic errors in AI agent outputs that result in unfair or discriminatory treatment of certain groups. Bias enters through training data (historical inequities reflected in the data), feature selection (proxies for protected characteristics), evaluation methodology (benchmarks that don't represent affected groups), and deployment context (using a model outside its validated use case). AI agents in HR, finance, healthcare, and legal applications must implement bias detection and mitigation as a core engineering requirement, not an afterthought.

Example

An AI resume screening agent shows differential accuracy across demographic groups—95% accuracy for one group, 78% for another. Bias monitoring catches the disparity, the team identifies that training data underrepresented the affected group, retraining with balanced data plus targeted evaluations brings accuracy within 2 percentage points across all groups.
