How to Use Analogies to Make Complex Ideas Easy to Understand

Have you ever talked to someone who is incredibly smart, but the moment they start explaining what they do, you feel like you’ve accidentally walked into a foreign language class? Engineers and technically minded people can sometimes speak in terms and acronyms that completely lose the rest of us. Their ideas are brilliant — but the delivery can make our brains stall out.

The other day, I met a group of very bright engineers who were explaining the technology they developed for incredibly precise measurements — measurements made in nanometers.

They told me a nanometer is:0.000000001And they said it casually… as if that meant something to the rest of us.

Honestly, I was lost.

But then one of them said something that made everything suddenly click:

A nanometer is to a meter as the thickness of a welcome mat is to the height of the Empire State Building.

Now we’re talking. I can see that. I can feel the difference. I understand it.

That’s the power of analogies. Analogies take something complex and attach it to something familiar. When we compare a new idea to something people already know, we make the unfamiliar… understandable.

And this isn’t just helpful for engineers — it’s essential for everyone:

  • Leaders explaining strategy

  • Teachers explaining concepts

  • Parents explaining life lessons

  • Professionals explaining their work

If the other person looks confused, it doesn’t mean they’re not capable — it means the explanation isn’t connected yet.

So the next time someone gives you a blank stare when you're describing something you know well — don’t push harder, simplify smarter.Use an analogy. Paint a picture. Make it familiar.

Because understanding doesn’t happen when people hear you —it happens when they get you.
