Human in the Loop

In one line

A person who reviews or approves what the AI proposes before it takes effect.

Picture it

The pharmacist who checks the prescription the system printed before handing it over.

Under the hood

Effective only when the review is designed: what the person sees, what they can change, and how long they have. An 'Approve' button nobody designed turns into a person who stops reviewing and starts approving. Use it where a wrong action is costly, and measure how often the human changes the outcome.
