Human in the loop
Also known as: HITL · human oversight · human review
Human in the loop refers to the mechanism by which a person validates, corrects or refuses a decision produced by an automated system, before it takes effect.
The idea only has value if the intervention is meaningful: the person must have the information, the competence and the authority to contradict the system. One-click validation, in bulk, on a screen that explains nothing, is not one.
Several regimes make it a right where a decision significantly affects a person: they can ask that a human review it.
Someone also has to be designated. An escalation path leading to nobody named is a dead end, and it is the most widespread defect in systems that nonetheless advertise oversight.
What it means for a small business

So what actually applies to you?
