Teach-to-Test Learning converts private competence into an external test. The practitioner explains a strategy so another person can execute it, including the conditions, decisions, and reasons behind each action. Wherever the explanation becomes incoherent, the learner cannot apply it, or the same questions recur, a knowledge gap has been exposed. The practitioner then clarifies the concept, changes the instruction, or removes a tactic that cannot be justified. Teaching is therefore not merely communication after learning; it is an instrument for testing whether knowledge is structured and transferable. Repeating the cycle with real learners creates feedback that solitary practice rarely supplies and can improve both the underlying method and its presentation.
Origin
Annie Duke says that teaching poker seminars caused her to discard tactics she could perform but could not explain coherently enough for another player to execute.
Core principles
- 01Teaching forces tacit knowledge into explicit instructions
- 02An unexplainable tactic may rest on weak reasoning
- 03Learner questions reveal gaps and ambiguities
- 04Executable explanations are stronger than fluent descriptions
- 05Repeated teaching creates a feedback loop
How to run it
- 1
Choose a teachable unit
Select one strategy, concept, or decision pattern narrow enough to explain and demonstrate clearly.
Pro tip Use a real task with observable execution rather than an abstract topic.
Watch out A scope that is too broad will hide specific reasoning gaps.
- 2
Make the reasoning explicit
Describe the conditions, steps, trade-offs, and expected results in language another person can follow.
Pro tip Explain why each step exists, not only what to do.
Watch out Fluent jargon can conceal missing causal understanding.
- 3
Test independent execution
Ask the learner to apply the method without being rescued by the teacher.
Pro tip Use a fresh example rather than repeating the demonstration.
Watch out Do not mistake imitation for genuine transfer.
- 4
Study the friction
Track recurring questions, execution failures, and points where the explanation becomes inconsistent.
Pro tip Treat repeated questions as diagnostic evidence rather than audience failure.
Watch out Not every question proves bad teaching; some concepts legitimately require elaboration.
- 5
Revise or remove
Improve unclear components and discard tactics that cannot be explained or defended coherently.
Pro tip Teach the revision to a new learner to verify improvement.
Watch out Do not preserve a weak tactic solely because it has become habitual.
In the wild
While teaching intermediate poker seminars, Duke discovered that several things she routinely did could not be explained coherently enough for students to execute. She removed those elements from her own game rather than assuming the students were the problem.
→ Teaching improved the underlying poker strategy as well as its communication.
A presenter notices that each audience asks the same question. The presenter maps where the concept appears, tests a clearer explanation, and watches whether the question changes in later sessions.
→ Recurring audience friction becomes evidence for refining the material.
Common mistakes
Mistaking fluency for transfer
An explanation can sound polished while leaving learners unable to perform the method independently.
Blaming every learner
Repeated confusion across audiences often indicates that the method or explanation needs examination.
Keeping unjustifiable habits
A tactic that cannot be explained coherently may be intuitive expertise, but it may also be an unsupported habit that deserves testing.
Is it for you?
Best for
It is best for practitioners who can perform a skill but need to clarify, validate, or transfer their reasoning.
Not ideal for
It is less suitable for beginners who lack enough foundational competence to distinguish a knowledge gap from a teaching gap.
From the transcript
“if you want to get better at anything, try to teach.”
“I couldn't actually explain it coherently to another human being such that they could execute the strategy themselves.”
