Episode 14 — Fairness Definitions

Fairness in AI does not have a single definition but instead encompasses multiple, sometimes conflicting, interpretations. This episode introduces demographic parity, which requires equal outcomes across groups, equal opportunity, which ensures equal true positive rates, and equalized odds, which balances both true and false positive rates across populations. Calibration and individual fairness, which require reliable probabilities and consistent treatment of similar individuals, are also explained. Each definition reflects a different ethical and practical perspective, and learners are guided through their conceptual differences.Real-world examples illustrate how conflicting definitions create trade-offs. A hiring system may achieve demographic parity but fail equal opportunity if underqualified candidates are selected, while credit scoring systems may prioritize calibration at the expense of parity. The episode emphasizes that fairness must be contextual, shaped by regulatory requirements, organizational priorities, and stakeholder input. Learners are also reminded that fairness metrics alone do not guarantee just outcomes — they must be paired with governance processes and cultural commitments. By understanding fairness definitions in plain language, practitioners are better equipped to evaluate models responsibly.
