Make It Stick: The Power of Three
8 min read · Technique 8 of 12
"Government of the people, by the people, for the people." "Life, liberty, and the pursuit of happiness." "I came, I saw, I conquered." The most memorable phrases in history share a pattern: they come in threes. This is not coincidence. It is cognitive science.
Mehdi Hasan devotes Chapter 10 of "Win Every Argument" to the Rule of Three, a rhetorical principle that dates back to Aristotle. The human brain is wired to find patterns in threes. Two feels incomplete. Four feels cluttered. Three is the magic number for retention, rhythm, and impact.
The Neuroscience of Three
Mehdi Hasan explains why triads are so effective:
Pattern Recognition
Three is the minimum number needed to create a pattern. With three points, the brain detects a structure and locks it in. This makes your argument easier to follow and remember.
Working Memory
Human working memory holds roughly three to four items at a time. More than that and the audience starts forgetting earlier points. Three maximizes retention without overload.
Rhythmic Satisfaction
Three creates a natural rhythm in speech. The audience anticipates the third beat and feels satisfaction when it arrives. This rhythmic completion makes the argument feel conclusive.
"The Rule of Three pervades the very warp and weft of human culture because it works on both cognitive and rhetorical levels."- Mehdi Hasan, "Win Every Argument"
Where to Apply the Rule of Three
Mehdi Hasan identifies several key moments where the Rule of Three creates maximum impact:
Opening Statements
Set up your argument with three key points. "Today I want to show you three things: first, the problem is real. Second, it is getting worse. Third, we can fix it."
Argument Structure
Build your case on three pillars. Each pillar should be strong enough to stand alone but more powerful together. If one gets challenged, the others still hold.
Adjective Stacks
Describe with triads. "This policy is reckless, short-sighted, and dangerous." Three adjectives hit harder than two and stick better than four.
Closing Summaries
End with three takeaways. "Remember: it's real, it's urgent, and we can win." Give the audience a triad to carry out the door.
How DebateClub Trains the Rule of Three
Knowing the Rule of Three is easy. Applying it under pressure is hard. When you are thinking on your feet, it is easy to ramble into five points or stop at two. DebateClub builds the habit through structured practice:

└──────────────────────────────────────┘Building Triadic Arguments
Here is how the Rule of Three applies in practice:
"This policy has many problems. There are cost issues, and also implementation challenges. Some people worry about the timeline, and there are environmental concerns too. Not to mention the political obstacles and the impact on small businesses..."
"This policy fails on three fronts. First, it's unaffordable. Second, it's unworkable. Third, it's unnecessary. Let me show you why."
Clean, memorable, and sets up a clear structure for the rest of your argument.
The restructured version is not just shorter. It is more powerful because the audience can track your argument and anticipate where you are going. They remember "unaffordable, unworkable, unnecessary" long after they forgot the rambling list.
Classic Triad Patterns
Mehdi Hasan identifies several reliable triad structures that you can adapt to any topic:
Reusable Triad Templates
Problem-Solution-Result: What is wrong, what we should do, what happens when we do it.
Past-Present-Future: Where we were, where we are, where we're going.
Head-Heart-Hand: The logical case, the emotional case, the call to action.
Three Questions: "What do we want? When do we want it? How do we get it?"
Three Adjectives: "This is unfair, unnecessary, and unkind."
These templates work because they are flexible enough to fit any topic but structured enough to be memorable. Pick the pattern that fits your argument and let the triad carry your points home.
What Changes After Practice
After practicing triad structure across multiple debates, you will notice:
Automatic Structuring
You start naturally organizing thoughts into threes. What once required conscious effort becomes instinctive.
Clearer Communication
Your arguments become easier to follow. Audiences can track where you are and what comes next.
Better Retention
People remember what you said. Triadic structure creates hooks for memory that loose points cannot.
Stronger Closings
Your summaries land harder. Three takeaways stick where ten points blur together.
The Bottom Line
Lincoln, Jefferson, Caesar. The greatest communicators in history understood what neuroscience has since confirmed: three is the magic number for human memory. Not two. Not four. Three.
DebateClub builds this structure into every piece of prep material you receive. Your openings come in threes. Your arguments come in threes. Your closings come in threes. The more you work with triadic content, the more naturally you produce it yourself.
Make it clear. Make it rhythmic. Make it stick.
