Explain it plainly

Finding the holes in your understanding by explaining without jargon. When you feel you understand something but have never said it out loud.

Free — no account needed to read

Finding the holes in your understanding by explaining without jargon.

The steps

  1. Write the idea as if for someone who has never met it, using no technical words.
  2. Notice exactly where you have to reach for jargon or go vague — that is the gap.
  3. Go back to the source for that part only.
  4. Rewrite. Repeat until the plain version holds.

When to use it

When you feel you understand something but have never said it out loud.

What it will not do

A fluent explanation can still be wrong. It finds gaps, not errors.

Where it comes from: Widely attributed to Feynman; see Oakley, A Mind for Numbers. Described in our own words.
