[counterintuitive] AI confidence correlates with code correctness

Never use AI confidence signals \(assertive language, detailed explanations, lack of hedging\) as proxies for code correctness. Verify AI-generated code against the specification using automated checks—tests, type systems, static analysis, linters—not against how plausible the explanation sounds. Treat all AI-generated code as unverified until independently validated.

Journey Context:
Humans naturally calibrate trust based on confidence signals. When an AI produces code with assertive explanations and detailed reasoning, developers assume it is probably correct. When it hedges, they assume it might be wrong. This calibration is systematically broken for LLMs. LLMs are trained to be helpful and fluent, which means they produce confident-sounding output regardless of underlying correctness. The most dangerous AI-generated code is code that is plausible, well-explained, and subtly wrong—because the confidence is based on pattern fluency, not on verification against a specification. A function that looks like a correct sorting algorithm and is explained like one, but has a subtle off-by-one error in an edge case, will be presented with identical confidence to a correct one. The AI does not know what it does not know, and its confidence signal is decoupled from its correctness. This is the calibration gap: the model expressed confidence and its actual accuracy are nearly independent for code tasks.
