What Is the Rule of Three?
The rule of three is a guideline suggesting that a group of three information is more effective (memorable and emphatic) than other combinations of items. Whether you are composing a speech, spinning a yarn, or writing an article, three can be a powerful number to help strengthen your message and make it more memorable.
Definition: The rule of three is a writing and communication strategy that suggests that things that come in threes are inherently funnier, more satisfying, or more effective than other numbers of things.
Why Does the Rule of Three Work So Well?
There is some real brain science behind it:
- We are pattern-recognition specialists with our amazing brains.
- Three is the lowest number of substances for which there is a consistent pattern.
- Anything more than three is starting to seem like a list, not a point.
The “rule of three” in communication is effective in part because it makes things feel whole and complete, and it lends a feel of rhythm. Think of slogans like “Stop. Look. Listen.” or “Just Do It.” They’re snappy, punchy, and memorable.
How to Use the Rule of Three in Your Daily Life
The rule of three does not require you to be a professional writer or speaker in order to use it. It’s a simple strategy that anyone can use in everyday social exchanges in order to speak more clearly and persuasively. Let’s say you’re writing: Breaking your work into three clear and focused parts can help readers follow your thinking without interruption.
In emails, unless you really want to cloud the issue, do not bombard your readers with more than three takeaways to keep things as straightforward and clear for them as possible. When speaking, give three instances or rationales to back up your assertion, and your ideas will become more convincing and more memorable. In marketing, the rule of three pops up in memorable three-word slogans, taglines that people remember long after they’ve first heard or seen them. The beauty of the rule of three for newbies is just how easy and immediately impact it is, providing you with a concrete strategy to share your ideas confidently in any situation.
Examples of the Rule of Three
Want to see how it’s done? Here are other excellent examples of the rule of three:
- In speeches: “Government of the people, by the people, for the people.”
- In writing: “He came, he saw, he conquered.”
- In design: Three-step onboarding processes in apps or websites.
- In branding: “Eat Fresh. Think Fresh. Live Fresh.”
These three examples illuminate how, in storytelling, Ads, and even in UX design, the rule of three can work to turn bland concepts into memorable messages.
The History of the Rule of Three
The Rule of Three is one of the very oldest and most durable principles of effective communication and narrative. Its roots are in ancient civilizations, from Greece and Rome, where orators and philosophers knew that people remember three speech points more than any other grouping. The famous Greek philosopher Aristotle tells us that triads create a natural rhythm, + that this inevitably earns attention and makes ideas more easily digestible.
It wasn’t just old rhetorical tricks: From religious texts to folklore, culture is rife with examples of this evolutionary dynamic. For instance, many fairy tales and myths repeatedly rely on groups of three events or characters — the “three wishes,” the “three little pigs,” or the “three trials,” to name a few. That this pattern repeats itself also indicates a natural three-based cognitive inclination in human beings.
The Rule of Three vs. Other Writing Techniques
The rule of three is just one weapon in the writer or speaker’s arsenal. For example, some prefer to follow the rule of five, which uses five points or elements to delve deeper into a subject, or storytelling frameworks like the three act structure, setup, confrontation, and resolution.
But the power of three is special because three is the lowest number that makes a pattern robust enough to stick in our brains. One or two points leave something out; four or more are too many, they crowd the listener or reader.
Its versatility is what makes the rule of 3 also effective across formats from speeches and essays to marketing copy and social media posts. It’s easy enough for beginners and powerful enough for experts, which is why it’s still a favorite today.
Place it in comparison with other similar methods when and why the rule of three comes in handy finally starts to make sense. For fast, good communication, it’s usually the right move. For any more complex or detailed concepts, it may be supplemented or succeeded by other means.
A Simple 3-Step Formula to Apply the Rule of Three
Here’s an easy way to start:
- Start with your point – What’s the one thing you want to say?
- Break it into 3 supporting ideas – Not 2, not 4.
- Phrase it rhythmically – Make it sound natural.
Say you are presenting:
“Success comes from vision, discipline, and action.”
You see how that would land better than a ramble of ideas? That’s what three principles in action can do.
Where to Use the Rule of Three
The rule of three is greater than a writing principle it’s a tool that can be used in a variety of forms of communication to ensure that your intended message is clear, complete, and memorable. For instance, it may save the day in public speaking when your speech is organized around three key points, like we saw previously t’s easier for the audience to follow and remember your main message, and this way you can deliver a natural rhythm and make your audience remain engaged. The rule of three is also frequently used in marketing copy to form product features or benefits into groups of three, making ad slogans and descriptions more interesting and convincing.
Teachers tap into this too, when they discuss lessons with their students based on three principles or outline three points for learners to remember. When it comes to social media, we have short attention, so if you’re able to plan captions or posts out in threes a hook, a value point, a CTA — you’re producing punchy content.
Whether you’re employing the rule of three to communicate or just structuring information into bullet points and bars of threes, the rule of three works across the board because it’s just how our brains process information, making ideas stick better and feel more complete.
Why Beginners Should Use the Rule of Three
If you’re just starting in writing or content creation, the rule of three for beginners offers a simple yet powerful structure to help you build confidence quickly. Using this technique makes you sound smarter because your ideas come across clearly and logically, which helps your audience follow along easily.
When you organize your thoughts into three parts, your messages stick better in people’s minds, making your communication more effective. Plus, the rule of three helps you create natural balance in your content without overthinking or overwhelming yourself with too many details. It’s no surprise that even expert speakers, writers, and creators rely on the rule of three every day to make their ideas memorable — and now, so can you.
Common Mistakes When Using the Rule of Three
The rule of three is straightforward, but also easily misapplied or overused, particularly by novices. The most consistent point of failure is trying to cram in exactly three points when the content just so happens to belong to the universe of topics that would have been more effectively represented by two or four points. Trying to jam in a third point that doesn’t truly enhance what you are saying may confuse the audience or cause your message to seem forced.
Another common mistake is that the three parts are simply too long or complicated. The power of the rule is in simplicity and rhythm each note should be laconic and crystal clear. When trying to make a point overly detailed or complicated, other than losing an audience’s attention, this negates the effort to make a message easier for people to remember.
Understanding these issues will help newcomers to the rule of three to use it as a powerful, natural way of creating balanced and engaging content rather than as a dry, formulaic gimmick.
Famous Examples of the Rule of Three in History and Culture
The power of three has produced some of the most memorable and memorable sentences in English. Abraham Lincoln’s speech at Gettysburg is one such example, closing with the well-known triad: “government of the people, by the people, for the people.” It’s just a catchy three-word phrase that’s perfectly square (like democracy miracles themselves), and a great encapsulation of the beating heart and main spirit of democracy.
Similarly, three ideals—life, liberty and the pursuit of happiness from the US Declaration of Independence encapsulate deep American values in a few short words.
These are only some of the many ways that the rule of three tends to pop up in all different aspects of culture, industry, and the media! Understanding this iconic usage enables the novice to appreciate the practicality and elegance of the rule.
How to Practice the Rule of Three in Daily Writing
It takes a little getting used to using the rule of three, but it’s easy to incorporate into your everyday writing. Before you write anything a blog post, email, a tweet or an Instagram caption start with three main points. Then, organize your message in a way that the points feel natural.
You can also test yourself by rewriting content with this three-point structure. Eventually, this will be second nature, and you’ll be creating clearer and more persuasive copy. Whether you’re a student, creator, or entrepreneur, adopting this rule can immediately improve your ability to communicate.
