Teach cases to solidify and test your own patterns
Explaining your recognition logic to others forces the implicit to become explicit and exposes gaps.
Key takeaways
- What it is: Explaining your recognition logic to others forces the implicit to become explicit and exposes gaps.
- Why it works: Teaching a domain requires generating explicit, communicable criteria — the same process as cue articulation, but with an external audience providing real-time feedback on whether the explanation makes sense. The generation process also deepens encoding of the pattern, and the questions a learner asks reliably surface the edge cases and exceptions the teacher’s pattern handles poorly. This is the Feynman technique applied to judgment rather than factual knowledge.
- Evidence: Backed by observational / correlational evidence.
- Avoid: Teaching the outcome decision ("I went left") rather than the recognition cues that led to it (" I went left because the smoke was low-velocity and the color was off") — the cues are what transfers.
Why it works
Teaching a domain requires generating explicit, communicable criteria — the same process as cue articulation, but with an external audience providing real-time feedback on whether the explanation makes sense. The generation process also deepens encoding of the pattern, and the questions a learner asks reliably surface the edge cases and exceptions the teacher’s pattern handles poorly. This is the Feynman technique applied to judgment rather than factual knowledge.
How to do it
- 1Identify a domain decision you make fluently and volunteer to walk a less experienced person through a real case.
- 2Explain specifically what you noticed, what it told you, and what would have told you something different.
- 3Pay attention to the questions where you can’t give a crisp answer — those indicate shallow pattern coverage.
- 4Update your cue list based on what you could not explain clearly.
What the evidence says
ObservationalTeaching-for-learning effects are well documented in educational psychology: generating explanations improves retention and comprehension relative to passive review. Application to tacit expert knowledge is a standard method in cognitive task analysis and professional mentorship, though direct RCT evidence for this specific use is limited.
Honest caveat: Teaching-for-learning is best studied in academic knowledge domains; transfer to tacit perceptual expertise is plausible but less directly tested.

Common mistake
Teaching the outcome decision ("I went left") rather than the recognition cues that led to it (" I went left because the smoke was low-velocity and the color was off") — the cues are what transfers.
IX Coach prompts you to narrate your reasoning on decisions, not just to record the outcome, so the session itself functions as a structured teach-back that firms up your pattern library.
