How do I practice domain specificity?

Pick three domains where you make predictions: your professional work, a hobby, and personal finance. For each, write down five predictions with confidence levels (e.g., '80% confident this will ship by Friday'). Track outcomes over two weeks. Compare your calibration across domains. You will almost certainly find that one domain is dramatically better calibrated than the others.

Common pitfall: Assuming that because you've developed good judgment in your profession, your intuitions about politics, health, investments, or relationships are equally trustworthy. The feeling of confidence is identical across domains — the accuracy is not. You'll know you've fallen into this trap when you catch yourself saying 'trust me, I have good instincts' about a topic where you have no track record.

This practice connects to Perceptual Calibration — building it as a repeatable habit compounds over time.
