The Reddit Revolution: Explain Like I'm Five
In 2011, a subreddit called r/explainlikeimfive (ELI5) was born. The premise was simple: explain complex topics, quantum physics, economic policy, philosophical concepts, as if you were talking to a five-year-old.
What started as a fun internet experiment revealed something profound: When you're forced to explain something simply, you're forced to truly understand it. And when you truly understand it, you can teach it to anyone.
The ELI5 method has since become a gold standard for clear communication. It's used by teachers, scientists, business leaders, and communicators worldwide. Why? Because it works.
At Wellspoken, we believe that the ability to teach complex ideas simply is the ultimate test of mastery. If you can make a five-year-old understand it, you can make anyone understand it.
Why Simple Teaching Works
Complex ideas feel heavy because your listener's brain can only juggle a few new pieces at once. The ELI5 mindset works because it does two things:
- Hooks the new idea to something they already understand.
- Shrinks the information into tiny, concrete pieces.
When you do that, people learn faster, feel less intimidated, and actually remember what you said.
The ELI5 Framework: Teaching Complex Ideas Simply
You don't need a complicated script. Use this simple flow:
- Start with what they know. "You know how...?" Begin from a familiar object, situation, or habit.
- Say the core idea in one plain sentence. "[Concept] is basically..." Avoid jargon and details.
- Give a concrete picture. Use everyday visuals so they can literally see it in their head.
- Add one key detail. Only the piece that matters most for this situation.
- Check understanding. Pause. Ask, "Does that make sense?" or "How would you explain it back?"
If they can explain it in their own words, you've nailed it. If not, simplify again instead of adding more detail.
The ELI5 Pattern (Fill-in-the-Blanks)
Use this as a quick mental template:
"You know how [familiar thing]? [New concept] is basically [simple explanation]. It’s kind of like [analogy]. The important part is [one key detail]. This matters because [real-world reason]."
Common ELI5 Traps
- “Simple” jargon. Words like API, server, leverage still assume expertise. Swap them for everyday objects and actions.
- No reason to care. Ending with a definition instead of why it matters makes people forget it instantly.
- Too many details. ELI5 is about the essential truth, not the full textbook.
Ask yourself: could a smart 12-year-old repeat this back and tell you why it matters? If not, cut and simplify again.
Quick ELI5 Drills
- Five-year-old test. Explain one hard concept from your world as if to a child. Record yourself and listen: where did jargon sneak in?
- One-sentence summary. For any topic, write one ELI5 sentence that someone outside your field could repeat.
- Analogy bank. List 5-10 everyday things (restaurants, libraries, streets, games) you can reuse as analogies when you’re stuck.
The Wellspoken Advantage
When you can explain ideas at an ELI5 level, you:
- Prove you really understand them.
- Reach people far outside your domain.
- Build trust because clarity feels confident.
Start small: pick one complex idea today and walk someone through it using the pattern above.
