[synthesis] Why one AI hallucination destroys more user trust than 100 correct answers build

Design AI error budgets around maximum single-error severity, not average error rate. A 5% error rate of hedging and refusal is far better than a 1% error rate of confident hallucination. Implement confidence calibration so that uncertain outputs look uncertain. Prioritize preventing high-severity confident-wrong outputs over reducing overall error count.

Journey Context:
In traditional software, trust is roughly symmetric: a bug annoys, a fix restores. Users understand software has bugs and forgive them. In AI products, trust is catastrophically asymmetric. The synthesis: combining Lee & See's research on trust in automation \(showing trust recovery is far slower for errors of commission—doing wrong things—than errors of omission—not doing things\) with the observation that AI failures are perceived as 'betrayal' rather than 'malfunction' reveals that AI products need a fundamentally different error budget. Users forgive software bugs because they understand the system followed rules that broke. Users don't forgive AI hallucinations because the AI appeared to understand and chose to assert a falsehood with confidence. This means the shape of the error distribution matters more than its mean: reducing error rate from 5% to 2% matters far less than ensuring the remaining 2% errors are low-severity and low-confidence. A confident wrong answer is worse than an honest 'I don't know.'
