[counterintuitive] AI expresses high confidence on wrong answers for out-of-distribution inputs

Never use AI's expressed confidence as a reliability signal. Instead, assess whether the input is close to common patterns in the training distribution. For novel, unusual, or edge-case code patterns, default to human verification regardless of how confident the AI sounds.

Journey Context:
AI models are systematically miscalibrated: they express high confidence on inputs that are out-of-distribution but superficially similar to training data. A senior engineer says 'I'm not sure about this' on unfamiliar territory; AI says 'here's the solution' with equal confidence for both common and novel problems. This is the most dangerous calibration failure because humans naturally use expressed confidence as a reliability signal—we trust confident answers more. With AI, that signal is noise. The practical consequence: AI will be confidently correct on well-represented problems \(reinforcing trust\) and confidently wrong on edge cases \(exploiting that trust\). The defense is to decouple your trust from the AI's confidence and instead anchor it on the distance between the current problem and known-well-solved problems.
