Label Bias

Systematic errors in data annotations caused by the subjective judgments, cultural backgrounds or incentive structures of human annotators.

In plain language

When the humans labelling data bring their own biases to the task. If annotators consistently rate certain accents as "less professional" or certain demographic groups more negatively, the AI trained on that data will learn and amplify those biases.

Why this matters

Label bias is a data governance risk that directly affects AI fairness and performance across demographic groups. Your governance framework must include quality assurance for data labelling, including diverse annotator teams, clear labelling guidelines, inter-rater reliability checks and periodic audits of labelling consistency across demographic groups.

Relevance

Governance

Label bias can embed discriminatory patterns into AI systems, requiring governance controls over data annotation processes to ensure fairness.
