What’s so magical about the number three?
It’s no accident that the number three is pervasive throughout some of our greatest stories, fairy tales and myths.
It’s also no coincidence that some of the most famous quotes from throughout history are structured in three parts, nor is it surprising that the Rule of Three also works wonders in the world of comedy.
It all comes down to the way we humans process information. We have become proficient at pattern recognition by necessity, and three is the smallest number of elements required to create a pattern. This combination of pattern and brevity results in memorable content, and that’s why the Rule of Three will make you a more engaging writer.
Storytelling
Have you ever wondered:
- What the three little pigs, the three blind mice, Goldilocks and the three bears, the Three Musketeers, the three wise men and the Three Stooges have in common?
- Why the three-act structure is the dominant approach to screenwriting in Hollywood?
- Why three bullet points are more effective than two or four?
The Rule of Three works in stories due to the presence of the concise, memorable patterns that I mentioned above. But even if that wasn’t the case, the number three has been used so widely throughout some of the most memorable works from our childhood, it’s likely that we are preconditioned to respond favorably to elements grouped in threes.
Think in terms of three when crafting your content, and you’ll likely end up with a more engaging outcome. If at first you don’t succeed, remember—the third time’s the charm.
Sticky Ideas
You see the Rule of Three used all the time across diverse areas of life. Why?
Because information presented in groups of three sticks in our heads better than other clusters of items. For example:
“Life, liberty, and the pursuit of happiness”
“Government of the people, by the people, for the people”
“Friends, Romans, Countrymen”
“Blood, sweat and tears”
“Location, location, location”
“Father, Son and Holy Spirit”
“Faith, Hope and Charity”
“Mind, body, spirit”
“Stop, Look and Listen”
“Sex, Lies and Videotape”
“I came, I saw, I conquered”
The United States Marines are big believers in the Rule of Three when it comes to getting things done and keeping people alive. The Corps apparently experimented with a rule of four, and retention and effectiveness took a nose dive.
If you want something stuck in someone’s head, put it in a sequence of three.
Humor
One of the best examples of the power of the Rule of Three is in the world of comedy. Again, three is the smallest number of elements that can form a pattern, and comedians exploit the way our minds perceive expected patterns to throw you off track (and make you laugh) with the third element.
The Rule of Three fits the classic joke structure of set-up, anticipation and punchline. The three-part grouping also allows for tension to build and then be released thanks to the surprise and absurdity contained in the third element.
Here are a couple of humorous examples that use a shocking third element within the Rule of Three structure. First up, Laura Kightlinger:
I can’t think of anything worse after a night of drinking than waking up next to someone and not being able to remember their name, or how you met, or why they’re dead.
Here’s one from Jon Stewart:
I celebrated Thanksgiving in an old-fashioned way. I invited everyone in my neighborhood to my house, we had an enormous feast, and then I killed them and took their land.
Using humor in your writing can be risky since some people just won’t get it, but using a Rule of Three approach is a safer way to make a funny. Professional comedians use it all the time, and that’s simply because it works.
Other Uses for the Rule of Three
I truly do believe that a set of three bullet points is the most effective use of the format. You might also find that list posts with three items will draw people in, because you’ve boiled things down to the essence with no fluff. And there’s a reason why people like to be presented with three choices rather than two or five.
When it comes to pleasing the human brain, it seems like three is simply a magic number. And that’s the truthiness, the whole truthiness, and nothing but the truthiness.

You said - ” You might also find that list posts with three items will draw people in, because you’ve boiled things down to the essence with no fluff. ”
Can you elaborate on that just a wee bit further, because I’m not sure what you mean, I’d like to see it in action and I think I can take action on it
It’s the “…list posts with three items…” that I’m looking to grasp a bit better.

Yeah, that’s what I meant. People will tell you that 7 is the ideal list length now, but I’ve had a lot of luck with three-item list articles too.
#3 lawton chiles → 12.17.07 at 5:31 pm
Great post buddy- it spoke to be through the practical use that 3 is better than four and so on- i didn’t really think about it but you hear it for years at least in church I do- the three points. Instead of two or four. More than three and i’m lost.
Beginning, Middle, Ending. Thanks for the reminder.

Triangles… Stools, cheerleaders’ pyramids, and bridges. Solid effective balance. And really great compositional dynamics. Three primary colors. Small, medium and large forms. Point, line,and plane . All essentials to making good art. Just read Kandinsky.
It is so very exciting for me, a painter, to find these rules of three work across disciplines.
As always you are brilliant, effective and timely.
Thanks Brian.
All best , Jan

Brian:
This got me trying to figure out why? and it is so obvious that I never saw it before.
There is only one shape that can be made with three lines once you have determined their length….a triangle (only mirror images or rotated images based on how you chose the pieces). As the number of lines grows beyond 3, the shape of the images can change based on the sequence in which the pieces are chosen.
Thus three is easy to remember and relate to because it is a constant.
That is why a triumvirate of power tends to be stable.
Now most readers will think I’m a nut but I get it….
Thanks

As a young PR account executive, I was taught the rule of three for effective presentations.
It is:
1. Tell ‘em what you are going to tell ‘em
2. Tell ‘em
3. Tell ‘em what you told them
It’s a simple but powerful way to help people to retain the main points of any presentation. Probably more useful in training young PR account execs, its a good way to ensure the presenter has a clear point to make!
So tell ‘em what you’re going to tell ‘em; tell ‘em; tell ‘em what you told them. Rather than sounding repetetive, use some of Brian’s many refinements to reinforce the message and add interest.
#20 bhumika → 12.18.07 at 3:00 am

#38 Adam Snider → 12.18.07 at 2:42 pm
Excellent article, Brian. I have no idea how I’ve never thought about or recognized the Rule of 3 before (at least, not on a conscious level). Very simple, yet incredibly effective.
I probably already employ this in my writing, without even realizing it. But, now, I’ll be making a more conscious effort to make use of it.
#39 Daniel Sutoyo → 12.18.07 at 2:55 pm
Great insight Brian!
I went out and start hunting on things that obeyed the rule of 3. Some of the things that came to my mind: new picture frames with 3 photos, hotel decor arrangements, movie trilogies (LOTR, Matrix)!
like your insight on 3 is the minimum number of creating a pattern. I also find 1-2-3 step process more appealing and friendly.
#40 Roberta Rosenberg → 12.18.07 at 5:11 pm
In line with the Rule of 3 , here is one more … odd numbers work better than even. This applies to bulleted phrases, lists, etc. (exception are variations on 10.)
I’ve often though that the reason odd numbers work better is that they create dissonance and therefore force more interest. Even numbers connote stability and balance and make us feel more peaceful - not what you’re looking for when you’re looking to engage your prospect/customer.
(I don’t have any research to support my thinking on this but if someone does, lay it on me!)
#41 LearningNerd → 12.18.07 at 5:26 pm
The number three is truly fascinating! I love how you’ve explained the concept with so many fun-to-read examples.
And I’m liking some of the theories in the comments here, lol. The rule of three is also very big in photography — look up the “rule of thirds”. A photo is often much more interesting when it’s broken up into thirds rather than halves.
#42 Arubicus → 12.19.07 at 5:48 am
Kinda funny. I was checking out many magazine headlines and behold there were tons that use the rule of 3. Here are a few examples.

One from Mens Health: New Year, New Body, New Life.
A third from MORE (my favorite): Moms in menopause, daughters in puberty, dads in hell

Another place the number three turns up is in the “Rule of Threes” that is taught by survival experts.
These simple to remember rules remind you how long you can survive in life-threatening situations:
* You can survive 3 minutes without air
* You can survive 3 hours without shelter
* You can survive 3 days without water
* You can survive 3 weeks without food
By learning (and applying) the “Rule of Threes” your chances of surviving a life-threatening situation go up. A lot!
Here is a good introduction to the “Rule of Threes” for setting survival priorities: http://www.survival.com/bookch1a.htm
I have used the “Rule of Threes” as the inspiration for my “ISV Survival” blog (http://isvsurvival.com/blog/) where I cover the life-threatening challenges that independent software vendors (ISVs) face in the shift to Software as a Service (SaaS).

Sadly there is a downside to this rule of three. When you think about the way organizations use taglines the recent trend is to find three descriptive words, plop some periods between ‘em, and call it done.
Three. Word. Tagline.
Sure it is comfortable. And it might even sound memorable… but the only thing memorable about it is that there are three words, not what those three words stand for.
Just one thought from a guy that writes names and taglines for a living.
#61 KEK → 01.23.08 at 8:52 pm
This makes total sense. There is a rule in proposal development that works without fail. In reading a detailed proposal, the brain naturally picks up the first line of a list, then jumps to the last, so classically, put the most important point in the 1 position, the 2nd most important point last. Then, it seems, the eye jumps to the 2 position, then next to last, then back up to the 3rd position. A pattern, until the eye and brain give up. So to make a more solid proposal, make only 3 points, that way, the reader can more effectively scan, reading point 1, 3, and 2, and then free to move to the next subject. Guaranteed to expedite the review, and probably increase success in marketing.
