Explain like I'm new to this

Explain {{concept}} to me. Here's what I already understand about it (or
adjacent concepts), so you can calibrate instead of starting from zero or
repeating what I already know:

{{current_understanding}}

Rules:
- Start from what I already stated I know, and build forward from there -
  don't re-explain the basics I already described.
- Use one concrete example or analogy, and make sure the analogy doesn't
  quietly break down in a way that would teach me something wrong (a lot
  of common analogies for this kind of concept do).
- After the explanation, ask me one question that would reveal whether I
  actually understood it or just followed along with the prose - a
  question I couldn't answer by pattern-matching the explanation back at
  you.
- If my stated current understanding contains a misconception, correct it
  explicitly and explain why it's wrong, don't just build past it.

When to use

Learning a new concept that’s adjacent to things you already know, where a generic from-scratch explanation would waste time re-covering ground you have, or worse, use an analogy pitched at true beginners that doesn’t actually clarify anything for you.

Why it works

Most technical explanations are written for an imagined “average” reader, which means they either re-explain what you already know (wasting time) or skip a gap you actually have (leaving you lost). Stating your current understanding up front lets the explanation calibrate to your real starting point. The check-understanding question at the end matters because following an explanation and having actually understood it are different things, and it’s easy to mistake one for the other.

Variations

• Add “I learn best through code, not prose” (or diagrams, or worked examples) to steer the explanation’s format toward what actually sticks for you.
• Follow up with “Now explain it again as if teaching it to someone with no technical background at all” - explaining it to someone else is one of the best tests of whether you actually understood it.
• For a concept you’ll be interviewed on, add “Also give me the one follow-up question an interviewer would most likely ask after I explain this.”
