[counterintuitive] AI confidence in generated code indicates correctness
Treat AI confidence as noise, not signal. Always verify AI-generated code through: \(1\) automated testing \(written independently, not by the same AI\), \(2\) static analysis tools, \(3\) human review for non-trivial logic. The gap between confidence and correctness is largest for tasks that seem simple but have subtle constraints — these are exactly the cases where confident wrong code is most dangerous.
Journey Context:
When an AI generates code with apparent confidence — no hedging, clean structure, plausible variable names — developers naturally assume it's correct. This is a systematic miscalibration. LLMs express high confidence in plausible-looking but incorrect code because their confidence reflects pattern familiarity, not correctness verification. The Kadavath et al. study showed that while LLMs have some ability to self-assess on factual questions, their calibration degrades significantly on tasks requiring precise reasoning — exactly the kind of tasks coding involves. The most dangerous case: code that looks correct, passes superficial review, and handles the happy path, but fails on edge cases the AI didn't consider. The AI's confidence is unchanged whether the code is correct or subtly wrong, because confidence comes from pattern fluency, not logical verification.
