[counterintuitive] High LLM confidence in generated code correlates with factual correctness

Treat LLM confidence as a measure of training data frequency, not correctness. Always verify code against official, up-to-date documentation for APIs, especially newly released or recently updated ones.

Journey Context:
LLMs exhibit severe miscalibration: they are highly confident when generating patterns common in their training data, even if that data is outdated. Humans experience uncertainty when facing unfamiliar APIs; LLMs hallucinate plausible but non-existent methods with absolute certainty.
