Bias

A systematic difference in how an AI system treats or represents people, groups, objects, or outcomes that can lead to unfair or discriminatory results.

How the laws define this

Regulators uniformly view bias as systematic errors or undesirable outcomes in AI outputs that lead to unfair, unequal, or discriminatory treatment, requiring mitigation through design, oversight, or impact assessments. However, these frameworks diverge regarding the specific contexts and populations they prioritize. The Artificial Intelligence Regulation Bill (Legislative Assembly) specifically targets harms against protected groups, whereas Considerations for the Use of Artificial Intelligence To Support Regulatory Decision-Making for Drug and Biological Products emphasizes inaccurate or unfair results across diverse patient populations. Additionally, the Plan de Acción para la Política Nacional de Inteligencia Artificial (Action Plan of the National AI Policy) uniquely isolates root causes—tracing bias to data, model design, labeling, or deployment contexts as a rights-related risk—while the Resolución de Presidencia N° 206/2025 - Anexo I “Guía de Recomendaciones y Directrices para el Uso de Sistemas de Inteligencia Artificial (IA) en el Poder Judicial de la Ciudad Autónoma de Buenos Aires” focuses on preventing systems from generating, reproducing, reinforcing, or perpetuating unfair treatment.

Definitions (4)

Systematic errors in AI systems that produce unfair or discriminatory outcomes, particularly against protected groups, which the regulation requires to be identified, assessed, and mitigated through bias prevention measures and impact assessments.

Systematic distortions in AI outputs or decision-making that produce unequal, unfair, or discriminatory outcomes for individuals or groups, arising from data, model design, labeling, or deployment contexts; the Plan frames bias as a rights-related risk to be detected, measured and mitigated.

Understood as undesirable outcomes where AI systems might generate, reproduce, reinforce, or perpetuate unfair treatment. The guidelines aim to prevent this through careful design and oversight.

The guidance also implicitly touches upon concepts like Bias, referring to systematic errors in an AI model's output that could lead to unfair or inaccurate results, particularly across diverse patient populations.

Not to be confused with

Fairness

Fairness refers to the absence of bias or discrimination, while bias is the systematic difference or error that causes unfair treatment.

Algorithmic Discrimination

Algorithmic discrimination is the unfair differential treatment caused by AI systems, often unlawful, whereas bias is the underlying systematic difference leading to such outcomes.

Questions and answers

What causes bias in AI according to Chile's National AI Policy?

Bias arises from systematic distortions in data, model design, labeling, or deployment contexts. The Action Plan frames it as a rights-related risk.

How does the Buenos Aires judiciary guideline address bias?

It understands bias as undesirable outcomes and aims to prevent it through careful design and oversight of AI systems.

What obligations does Costa Rica's AI bill propose for bias?

It would require systematic errors causing unfair outcomes, especially against protected groups, to be identified, assessed, and mitigated using prevention measures and impact assessments.
