How do I practice expert intuition?

The most direct way to practice expert intuition is through a focused exercise: Choose a domain where you have genuine expertise — your profession, a deep hobby, a subject you have studied for years. Now choose a domain where you are a novice — something you started recently or know little about. For each domain, spend ten minutes consuming new information (an article, a video, a document). As you consume, notice and log: (1) how quickly you can identify what matters, (2) how much of the content you skip or skim without losing comprehension, (3) how many connections you make to things you already know, (4) how confident you feel about what to ignore. Compare the two experiences. The gap between them is the gap between having signal detectors and not having them. That gap is what this lesson explains.

Common pitfall: Confusing information volume with expertise. The failure mode is believing that experts know more facts, so the path to expertise is accumulating more facts. This produces what researchers call 'verbose novices' — people who can recite extensive information about a domain but cannot identify what matters in a specific situation. They have memorized the noise along with the signal and cannot tell them apart. Expertise is not a larger database. It is a better filter.

This practice connects to Phase 7 (Signal vs Noise) — building it as a repeatable habit compounds over time.
