Pinpoint where the explanation breaks
Treat every stumble, hand-wave, or jargon-grab as a flag for a real gap.
Why it works
The places where your explanation stalls are where understanding is actually thin — the generation effect exposes them because you cannot fluently produce what you do not truly know. Marking those points converts a vague sense of "I sort of get it" into a precise list of what to fix.
How to do it
- Mark each spot where you got stuck or fell back on undefined terms.
- Ask "why?" and "how?" at each flag until you hit the edge of what you can say.
- Write the gap as a specific question you cannot yet answer.
Evidence
This step targets the illusion of explanatory depth — the well-documented finding that people believe they understand mechanisms far better than they can actually explain. (observational)
Knowing a gap exists is not the same as closing it; this step diagnoses, the next step treats.
Common mistake
Glossing over a stumble as a wording problem and pushing on, instead of stopping to admit you have located something you do not understand.

- Explain it to a complete beginner
Teach the concept in plain words to someone who knows nothing about it.
- Go back to the source and relearn the gap
Take each flagged gap back to the material and close it specifically.
- Simplify the language and add an analogy
Rewrite the explanation in everyday words and anchor it to something familiar.
- Run the loop until it is smooth
Repeat explain–diagnose–relearn until you can explain the whole thing without snags.
- Teach it to a real person
Explain the concept to an actual listener who can ask questions back.
