Every AI vendor in the title business — ours included — now says the words “human in the loop” somewhere in the pitch. It’s the phrase that makes AI palatable in a regulated industry: the machine proposes, the human disposes, everyone sleeps at night. Here’s the uncomfortable part: most human-in-the-loop designs are rubber stamps with extra steps, and the humans inside them know it before the vendors do.

The Rubber Stamp Problem

The failure has a name — automation bias — and a shape every operator will recognize. Put a person in front of a system that’s right 98% of the time and ask them to catch the 2%, and their vigilance decays on a schedule. The first week, they check everything. By the third month, they’re approving on rhythm, because every check they’ve done has confirmed the machine. The review becomes a click. The loop is still there on the org chart and in the compliance narrative; it’s just not doing anything.

I watched aviation learn this over my entire flying career. Cockpit automation genuinely made flying safer — and it created a new accident category that barely existed before: crews monitoring a system they no longer fully tracked, discovering in the worst possible moment that the autopilot had been doing something other than what they assumed. The industry’s answer wasn’t less automation. It was redesigning the human’s role — what the automation announces, what it hands back, and what the crew is required to actively do rather than passively watch. The lesson transfers to a closing office intact: the question is never whether there’s a human in the loop. It’s whether the loop is designed so the human is actually doing something.

What a Real Loop Looks Like

A few design properties separate real review from ceremonial review. The system has to show its evidence, not its confidence. A score of 94 out of 100 gives a reviewer nothing to do but trust it — there’s no handle to grab. An itemized flag — this routing number doesn’t match the named bank, this per-diem doesn’t compute, this date is stale — gives the human a specific, checkable claim. One is a verdict to accept; the other is a lead to run down. Humans are bad at sustained vigilance and good at running down leads. Design for the thing they’re good at.

The review has to be cheap, or it will be skipped — not officially, just functionally, in July, at 4:45, on the file that looks fine. If checking the machine’s work takes longer than doing the work, your loop exists only in the compliance binder. And the human’s decision has to be recorded — what was flagged, what they did about it, when. Partly because that’s what makes the loop auditable, and partly because a person who knows their judgment is the documented decision behaves differently from a person clicking through a queue.

Matching the Loop to the Stakes

None of this means everything needs a human. That’s the other way to kid yourself — a loop on every low-stakes, reversible step is how you burn your team’s vigilance budget on things that don’t matter, so it’s exhausted when something does. Indexing a document, formatting a commitment, drafting a status email: let the machine run, audit samples afterward. The full advisory treatment — evidence-based flags, cheap active review, recorded decisions — belongs on the small set of decisions that are irreversible and expensive: releasing a wire, waiving a requirement, insuring over a defect. The June post on AI eating the title industry made the macro version of this argument. This is the micro version: adoption succeeds or fails at the level of individual workflow design, one decision at a time.

So when a vendor says “human in the loop,” ask the design questions. Does it show evidence or a score? What does reviewing one item cost the reviewer? Is the human’s decision recorded with what they saw? And is the loop placed where the stakes are, or everywhere, decoratively? The phrase is cheap. The design is the product.
