Use the Powerful Rule of 3 to Communicate

If you want to be a better communicator, you need to know three things.

Wait, let me be more clear. If you want to be a better communicator, you need to know things about Three.

Using the power of three to structure your messages, make your points or tell your stories can make what you say more clear, understandable and memorable.

That's because patterns of three dominate our lives, our thinking, and our culture.

Just look around and you'll realize that from fairy tales to public life to the sentence you're reading, the number three is omnipresent. Here are some of the more obvious examples:

Three little pigs

Three blind mice

Three musketeers

Three stooges

Goldilocks and the three bears

Easy as A, B, C

Life, liberty and the pursuit of happiness

Government of the people, by the people and for the people

Father, Son and Holy Spirit

Blood, sweat and tears

Earth, wind and fire

Sex, Drugs and Rock n' Roll

Beginning, Middle, End

Introduction, Body, Conclusion

You get the idea. Three is everywhere.

Why is The rule of three so embedded in our lives and cultures? Three is so powerful because it's:

1. Favored by humans

We seem to have developed a deep affinity for three elements together; they feel complete and solid. One is too few and two feels not enough, but three is a solid set. Three somehow has a connected rhythm that seems appealing.

2. Easy to remember 

In the same way, three is easy for our brains to remember. It's hard to remember four or five items but three is manageable for most people.

This is critical as we live in a digital, social world where our attention spans are nil.

Rather than having five, seven or ten priorities for your team, have three. After all, if they're really priorities, they should be few.

3. Most persuasive 

Researchers at UCLA and Georgetown found that three claims are perfect for persuasion in public settings, such as advertising, politicians' speeches and other persuasive communication. They found that four or more claims will trigger people's skepticism and can actually make it less likely that the person will be persuaded.

4. A persuasive pattern 

Previously, the same researchers concluded that when we see events happen three times in a row we believe that they constitute a streak, as in stock index movements, coin tosses or basketball shots.

5. Funny

Comedians frequently use the rule of three in jokes. There are always three people of diverse interests sitting in a boat. One says something, the second says something, and the third delivers the punch line. Or a joke like this, whose author is anonymous: A printer consists of three main parts: the case, the jammed paper tray and the blinking red light.

Clearly, three is pervasive in our culture.

I'd recommend that you consider using the rule of three as you seek to inform, persuade or entertain people. In fact, as I wrote in 7 Ways to Organize Your Presentation, the classic three-part is the simplest way to structure your presentation:

1. Opening: For example, in a presentation talk about your major idea in the opening and then give three points to support that contention.

2. Middle: In the body of your talk, walk through each of those three points, adding an example, a statistic or a story to support each one.

3. Close: Finally, in your conclusion, summarize your idea in three points and ask people to act on what you've outlined.

This format can be used in any presentation or persuasive communication. It's clear, concise and complete.

That's because it makes use of a powerful tool: the rule of three.
