How to Come Up with a Good Analogy for a Complex Idea (When Nothing's Coming to Mind)
To come up with a good analogy, reduce the idea to the one feature doing the explaining, then find that feature in something your listener knows well. Check it works in reverse, say where it breaks, and let the listener make the last connection.
- Reduce the idea to the one feature that matters.
- Look for that feature in the listener's world.
- Check it works backwards to the original idea.
- Say where the analogy breaks.
- Let them make the last connection.
A good analogy for a complex idea maps one essential feature of the idea onto something the listener already understands. Compound interest, for example, is about gains generating their own gains; the internet is about any point connecting to any other. Finding the analogy is a search procedure: name that feature, look for it in the listener's own world (cooking, sports, parenting), test whether the comparison leads back to the right idea, and say plainly where it stops applying.
You know what you mean, and the right comparison is hovering just out of reach. Everything you try is either too obvious or too clever. The people who seem to produce analogies effortlessly are usually running the same few steps.
How do you find a good analogy?
An analogy doesn't need to capture everything — it needs to capture the one feature that's doing the explanatory work. Compound interest matters because of the recursion: gains generating their own gains. The internet matters because of the directionless connectivity: any node to any node. Once you know which feature you're highlighting, the search space narrows enormously. Analogies often fail because the author tried to carry over too many features at once.
Where should you look for an analogy that fits your audience?
Don't search the universe — search the listener. If they cook, scan kitchen domains. If they parent, scan parenting situations. If they play sports, scan athletic dynamics. The best analogies aren't from the most clever domain; they're from the domain the listener can move around in fluently. A clumsy analogy from their world beats a brilliant one from a domain they have to translate from.
How do you know if an analogy works?
Once you have a candidate, ask: if I described the analogy without naming the original concept, would someone arrive back at the right concept? If you say 'it's like a thermostat,' would they correctly guess feedback loop, or might they guess temperature, control, or comfort? An analogy that maps to too many things isn't an analogy — it's a generic image. Trim or pick a different one.
Should you say where an analogy breaks down?
Every analogy fails somewhere. Name the failure point out loud — it earns trust and prevents the listener from over-extending. 'It's like compound interest — except unlike money, attention compounds whether you choose to invest it or not.' Naming the seam tells the listener you're using the analogy as a tool, not making a claim. Skipping this step is what turns a useful comparison into a misleading one.
How much should you explain after giving an analogy?
The best analogies don't fully explain themselves — they hand the listener enough scaffolding to do the last step on their own. Say less than you want to. Trust them to make the final connection. When someone says 'oh, so it's like...' and lands somewhere true, that's worth ten of your sentences. The analogy stuck because they built the last piece of it.
