Report #104134

[counterintuitive] Humans are good at estimating how hard a bug is to fix

Use issue triage data and historical fix times rather than gut feel. Both humans and LLMs systematically underestimate bugs in unfamiliar subsystems and overestimate bugs in code they recently touched.

Journey Context:
Bug difficulty estimation is plagued by the curse of knowledge and availability bias. A bug in a familiar module feels easy because you know the context; a bug in an unfamiliar module feels hard because you lack context. LLMs replicate these biases from their training data. Empirical software engineering data shows actual fix time is poorly correlated with initial estimates. The fix is to use historical data, risk matrices, and structured pre-mortems instead of intuition.
