[synthesis] High AI reliability causes automation complacency: users stop verifying outputs, so the system's best performance seeds its worst failures

Design interfaces that require active verification on every high-stakes output, celebrate caught AI errors as wins, and deliberately expose users to representative failure modes during training so they maintain judgment.

Journey Context:
Parasuraman and Manzey's automation-complacency research shows that as automation reliability rises, human vigilance falls — a well-documented pattern in aviation, healthcare, and driving. With LLMs the effect is compounded by epistemic fluency: outputs look right even when wrong. The result is an inverted-U of trust where moderate error rates keep users alert, while very high accuracy lulls them into blind acceptance. This means improving model accuracy can paradoxically increase catastrophic failure risk if the UI does not also maintain human engagement. The fix is not more explanations \(which can increase over-trust\) but structured verification workflows, calibrated override points, and failure-mode drills that keep users' mental models accurate.
