[synthesis] Why users stop trusting AI confidence scores even when model accuracy has not changed

Recalibrate confidence scores on a rolling basis using recent production data, not training-time calibration. Expose confidence as ranges \('low/medium/high'\) rather than precise percentages—users tolerate range uncertainty better than point estimate failures. When the model encounters out-of-distribution inputs, explicitly surface low confidence rather than generating a confident-but-wrong output. Track calibration drift as a first-class metric alongside accuracy.

Journey Context:
Users learn to rely on AI confidence scores as trust signals: 'the AI says it's 95% confident, so I can trust this.' But confidence calibration drifts as input distributions shift—the model encounters data it wasn't trained on and remains confidently wrong. This is well-documented in calibration literature. The synthesis insight is about the trust dynamics: when users get burned by a confidently wrong output, they don't just discount that one output—they discount the entire confidence signaling system. They stop using confidence as a triage mechanism and start treating all outputs as equally unreliable, which eliminates the efficiency gain of being able to skip verification on high-confidence outputs. The product value drops not because accuracy changed, but because the trust calibration signal became unreliable. And unlike software where a broken indicator can be fixed and users will trust it again, confidence trust once broken is extremely hard to rebuild—users develop a permanent 'verify everything' habit that negates the AI's productivity value.
