Does Human in the Loop (HITL) mean Effective Human Oversight?
Putting a human in an #AI workflow is often presented as a safeguard. I've seen teams assign responsibility and accountability to a human, then build evals around the model only.
HITL is not a checkbox. It's a key component in the value chain. When you introduce human oversight, you acknowledge that the human possesses the necessary traits to make its presence meaningful. Whether that's acting on information surfaced by AI or assessing an AI action.
We've heard of lawyers filing briefs with non-existent precedents, clinicians approving drafts with factual errors, and safety drivers in test vehicles still having accidents.
In each case, a human was present and expected to recognise or respond to an error. Yet their involvement wasn't enough to prevent what happened next.

1. Domain expertise: Can do the job independently and knows where AI can err.
2. Calibrated judgement: Avoids both rubber-stamping and complete skepticism.
3. Vigilance: Can maintain attention even when the AI is consistently reliable.
4. Authority to disagree: Has the agency to override the system and flag errors.
5. Time to deliberate: Sufficient time to exercise judgement without the pressure of latency.

Having a human in the loop doesn't automatically translate into an AI system that is safer or better. That human needs self-awareness, competence, attention, time, and authority to critically evaluate the AI output.
If we evaluate models for accuracy and reliability, shouldn't we also evaluate whether the humans overseeing them consistently identify and correct AI's mistakes, or introduce errors of their own when the AI was right?
After all, the measure of effective oversight isn't whether a human approved an AI decision. It's whether the human-AI collaboration produces higher quality decisions than either could have achieved alone.
More interestingly, if the evals reveal that the AI consistently makes better decisions without much human intervention, what does that tell us about the value of having a human in the loop?
