[counterintuitive] AI model confidence correlates with accuracy—confident outputs are more likely correct

Treat AI confidence as uninformative for generation tasks. Always verify high-confidence outputs through independent means: compile checks, test execution, static analysis, human review. Never use the model's own stated confidence or authoritative tone as a signal to skip verification.

Journey Context:
Humans naturally calibrate confidence: when unsure, they hedge; when confident, they're usually right. This makes confidence a useful triage signal in human collaboration. LLMs break this social contract: they express high confidence regardless of correctness. Kadavath et al. showed that while LLMs can be somewhat calibrated on multiple-choice tasks, their confidence is poorly correlated with accuracy on generation tasks—the exact tasks coding agents perform. A model will state an incorrect API signature with the same authoritative tone as a correct one. The practical danger: developers learn to trust confident human output and transfer this heuristic to AI, skipping verification on outputs that 'look right.' The fix is structural: build verification into the pipeline regardless of confidence, because the confidence signal contains almost no information about correctness for generation tasks.
