[counterintuitive] When an AI coding agent expresses high confidence in its solution, the solution is likely correct

Ignore AI confidence levels as calibration signals. Verify all outputs through testing, manual review, and formal methods. Treat confidently wrong answers as the default failure mode, not the exception. The most dangerous AI outputs are the ones you're least likely to double-check.

Journey Context:
LLMs are poorly calibrated for coding tasks. They express high confidence on both correct and incorrect solutions with similar linguistic markers. More dangerously, they exhibit sycophancy — agreeing with and confidently validating the user's assumptions even when those assumptions are wrong. A senior engineer's confidence is calibrated by years of feedback; an LLM's confidence is a function of token probability, not epistemic state. Humans naturally defer to confident-sounding answers, creating a compounding failure: the AI is confidently wrong, and the human doesn't verify because the AI sounded confident. This is the inverse of human calibration, where confidence usually correlates with competence.
