What’s the most important number in the world? Let’s count.
One … two … three?
It’s an odd number to be fixated on. But we are. Look around you. Listen. Read. Everything comes in threes. We love things to be presented in trios.
Land, sea, sky. Birth, life, death. Child, adult, elder. Beginning, middle, end. Ready, set, go. Lights, camera, action. I came, I saw, I conquered. See no evil, hear no evil, speak no evil.
It’s a habit of humanity to divvy things up into threes. Maybe because it’s a nice prime number, like 5 or 7. There’s a pleasant sense of completeness in three, a satisfaction that you can’t quite get with two, and going up to four is a step too far. Three is everywhere, and it’s found a home in our collective psyche. Things always feel right when they’re grouped into threes. Stories feel right.
The number three is storytelling’s superstar. Stories rely on patterns, and the number three is the smallest number you can use to set up a pattern and then deviate from it. Take a glance at fairy tales and note how many times the third brother gets the prize, or how many trials the hero must overcome to succeed, or how many times the evil witch tries to stop him. Set up the expectation and then throw in a twist the third time around.
Good stories tend to be efficient with their time and words. Why go through the same pattern four times to set up the fifth’s deviation, when you can cut out two repetitions and get the same result? Maybe early oral storytellers were just lazy and hit on a good tactic to keep listeners engaged without wearing out their throats.
Either way, if you’re going to be a writer, consider the usefulness of the rule of three. Most stories are divided into three acts: The setup, the middle action, and the climax. Want to reinforce that a plot element is important? Mention it three times: Once to introduce it, a second time to remind your audience of its existence, and a third time for the payoff (alternatively, a third time to reinforce it in audience’s minds, and then give them the payoff).
Remember the oath that witnesses make in court? “Tell the truth, the whole truth, and nothing but the truth, so help me, God.” Here we see the principle in action: “Tell the truth” (introducing the concept to speak truthfully), “the whole truth” (reinforce the concept that you will be honest), “and nothing but the truth, so help me, God” (grinding it into your head that you will tell the truth, doggonit!)
As weird as the rule of three is if you think about it too hard, we’ve been raised on it for so long that it’s been hardwired into most societies. We tend to think in terms of threes when writing, when talking with friends, or even when giving a speech. It’s just such a common, reliable, and trustworthy trope. It’s in schools, it’s in media, it’s even in the academic community.
Ha, ha, yes, I’m so very clever. But you get the point. Don’t you? Need me to repeat it again?
In all seriousness, we humans do like patterns, and the rule of three is such a basic pattern that it fits pretty much anywhere. We recognize it, at least on a subconscious level, because we’ve been exposed to it since childhood. I can make that statement with confidence because it’s just. That. Widespread. And yes, I did just use the rule again to prove my point. Really, this whole article could drown in its own metatext.
Being so common, the rule of three is a reliable standby for writers both beginner and veteran. I use. You use it. And – Well, you get the idea.
The gods and beings of ancient myth never went away. They just moved on with the times.
My book, A God Walks up to the Bar, is currently available on Amazon.com. Venture into the world of the Greek god Hermes, a world filled with demigods, vampires, nymphs, ogres, magic, and trickery. It’s a tough job, being a god!
