What is human-in-the-loop artificial intelligence?

Definition

Human-in-the-loop artificial intelligence assigns defined decisions or review points to a person rather than allowing the system to operate entirely on its own. The human may provide context, approve consequential actions, correct errors, or decide how to handle ambiguity and exceptions.

Effective oversight is selective and evidence-rich. If a person must approve every routine click, the workflow can become slower than manual work and reviewers may stop paying attention. Automation should handle reversible low-risk execution while presenting meaningful decisions, context, and consequences clearly.

Frequently asked questions

When should a human review an artificial intelligence agent's action?

Human review is most important for consequential, irreversible, ambiguous, high-risk, or authority-expanding actions and when expected evidence is missing.

Can too much human supervision reduce safety?

Yes. Excessive low-value prompts can cause fatigue and superficial approval, so systems should focus attention on decisions that genuinely need judgment.
