Farnam Street

This essay is not about demos, it is about the underlying test our short answer relies on: if you cannot explain something simply, you have not distilled it enough, and complexity is often a sign you are hiding a gap rather than protecting a nuance. Run your own demo script through this test before you deliver it. If you find yourself reaching for jargon to get through a moment, that is the exact moment worth cutting or rebuilding.

From Farnam Street

• Inability to explain something simply usually means the explanation, not the audience, is the problem
• Writing an explanation down exposes the gaps that talking through it lets you paper over
• Jargon is frequently a substitute for understanding, not a sign of it
