What is domain specificity?

Being well-calibrated in one area does not transfer automatically to others.

Example: A senior engineer who accurately estimates software project timelines within two weeks consistently gets blindsided by home renovation budgets, investment returns, and how long it takes to learn a new language. Her calibration — hard-won through thousands of shipping cycles — lives inside the domain where she built it. Outside that domain, she's as overconfident as anyone else.

This concept is part of Perceptual Calibration in the How to Think curriculum, which builds the epistemic infrastructure for perceptual calibration.
