Map who is affected and how its output is used, check whether data and labels fit that setting, test relevant outcomes and errors across groups, give reviewers meaningful authority, and monitor results after deployment. NIST’s voluntary AI Risk Management Framework offers one way to organize that work: Govern, Map, Measure, and Manage.
What bias in an AI-assisted decision can look like
Bias is not limited to a model producing different results for different groups. It can enter through data collection, missing or unrepresentative examples, labels that encode past decisions, design choices, the setting in which a system is used, or the way people interpret its output. Deployment can introduce further problems if the population, workflow, or conditions differ from those the system was developed for.
Start with the possible harm: who could be disadvantaged, in what decision, and through which part of the process? A model’s overall accuracy or a single fairness score cannot answer that question on its own. A system can perform well on one measure while distributing errors or consequences unevenly.
How to assess and reduce bias
Use the following workflow before deployment and revisit it when the system or its context changes. NIST’s 2022 publication Toward a Standard for Identifying and Managing Bias in Artificial Intelligence (SP 1270) treats bias as a set of connected risks, rather than a problem that can be solved by adjusting one dataset or metric.
#1 Best Overall
- Map the decision. Describe the decision being supported, who makes it, who is affected, what the AI provides, and how that output influences the final result. Include the real operating environment and the communities affected. Identify which errors or unequal outcomes could cause meaningful harm.
- Examine the data and labels. Ask who is represented or missing, how labels and target outcomes were produced, and whether historical outcomes may reflect unequal access or treatment. Check whether the available data suits the intended population and use. Record missingness and uncertainty; dataset size alone does not establish representativeness.
- Define the evaluation questions. Select groups and comparisons that relate to the identified harms. Assess relevant outcome differences and how errors are distributed. State which errors matter, why they matter, and what trade-offs a chosen measure makes. Do not treat any one fairness metric as a universal pass/fail test.
- Test the system in realistic conditions. Use data and scenarios that reflect the intended setting. Include cases with incomplete inputs, populations that differ from development data, and plausible unexpected uses. Examine not only model outputs but also how people interpret and act on them.
- Choose controls and document the decision. Depending on what testing shows, controls might include collecting or improving data, revising labels or design, limiting permitted uses, changing a workflow or threshold, strengthening oversight, or not deploying. Record the rationale, responsible owners, results, affected populations, and known limitations.
- Monitor and reassess. Track outcomes and errors after release. Revisit the assessment when the model, workflow, population, or decision context changes; a pre-release test cannot establish how a system will perform under later conditions.
Which fairness metric should you use?
Choose a measure only after defining the decision, affected people, and harm to be prevented. The useful comparison depends on what the system does: for example, which outcomes count, which errors carry the greatest cost, and whether the evaluation represents the deployment setting. Explain what the selected measure captures and what it leaves out.
Comparisons may also involve sensitive information about people. Consider privacy implications alongside whether the groups and outcomes needed for a meaningful evaluation can be represented. A metric that addresses one disparity does not, by itself, settle unequal error costs, privacy, operational feasibility, or people’s ability to challenge a result.
Can human review prevent AI bias?
Human review can be a control only when it is meaningful. A reviewer needs enough information and support to understand the system’s role, question an output, and override it where appropriate. If workplace expectations or workflow design make the AI recommendation effectively mandatory, nominal human approval may not provide real oversight.
For consequential decisions, define when a reviewer can challenge or override an output and how an affected person can seek correction or review. Evaluate these steps as part of the system: look at how reviewers use the output in practice, not just whether a human is technically present in the process.

NIST AI RMF 1.0, published in 2023, is a voluntary, use-case-agnostic framework. Its four named functions can help teams assign work across the lifecycle; they are not a guarantee that applying the framework will eliminate bias.
| Function | Role in bias management |
|---|---|
| Govern | Establish accountability, responsibilities, and organizational oversight. |
| Map | Describe the system’s context, intended use, affected people, and potential harms. |
| Measure | Assess relevant risks through appropriate evaluation, including technical and human factors. |
| Manage | Prioritize risks and select, document, and monitor responses. |
NIST provides a companion AI RMF Playbook with suggested actions and references. NIST’s framework page says AI RMF 1.0 is being revised and lists an April 7, 2026 concept note for a profile on trustworthy AI in critical infrastructure. Check NIST’s current materials when using the framework, since its status and related guidance can change.

What U.S. employers should know
For employment decisions in the United States, the EEOC says federal anti-discrimination laws still apply when employers use algorithmic tools. In an October 28, 2021 press release, then-EEOC Chair Charlotte A. Burrows said: “While the technology may be evolving, anti-discrimination laws still apply. The EEOC will address workplace bias that violates federal civil rights laws regardless of the form it takes, and the agency is committed to helping employers understand how to benefit from these new technologies while also complying with employment laws.”
That statement addresses U.S. employment and is not a complete legal analysis. Requirements can depend on the decision, applicable law, and jurisdiction; organizations should consult current regulator materials and qualified legal advice for a specific use.
