Given the importance of making ideas stick, it’s surprising how little attention is paid to the subject. When we get advice on communicating, it often concerns our delivery: “Stand up straight, make eye contact, use appropriate hand gestures. Practice, practice, practice (but don’t sound canned).” Sometimes we get advice about structure: “Tell ‘em what you’re going to tell ‘em. Tell ‘em, then tell ‘em what you told ‘em.” Or “Start by getting their attention—tell a joke or a story.” Another genre concerns knowing your audience: “Know what your listeners care about, so you can tailor your communication to them.” And, finally, there’s the most common refrain in the realm of communication advice: Use repetition, repetition, repetition. All of this advice has obvious merit, except, perhaps, for the emphasis on repetition. (If you have to tell someone the same thing ten times, the idea probably wasn’t very well designed. No urban legend has to be repeated ten times.)
In fact, perhaps the oldest class of naturally sticky ideas is the proverb—a nugget of wisdom that often endures over centuries and across cultures. As an example, versions of the proverb “Where there’s smoke there’s fire” have appeared in more than fifty-five different languages.
Proverbs are the ideal. We must create ideas that are both simple and profound. The Golden Rule is the ultimate model of simplicity: a one-sentence statement so profound that an individual could spend a lifetime learning to follow it.
We need to violate people’s expectations. We need to be counterintuitive. A bag of popcorn is as unhealthy as a whole day’s worth of fatty foods! We can use surprise—an emotion whose function is to increase alertness and cause focus—to grab people’s attention.
How do we make our ideas clear? We must explain our ideas in terms of human actions, in terms of sensory information. This is where so much business communication goes awry. Mission statements, synergies, strategies, visions—they are often ambiguous to the point of being meaningless. Naturally sticky ideas are full of concrete images—ice-filled bathtubs, apples with razors—because our brains are wired to remember concrete data. In proverbs, abstract truths are often encoded in concrete language: “A bird in hand is worth two in the bush.” Speaking concretely is the only way to ensure that our idea will mean the same thing to everyone in our audience.
How do we get people to act on our ideas? We tell stories. Firefighters naturally swap stories after every fire, and by doing so they multiply their experience; after years of hearing stories, they have a richer, more complete mental catalog of critical situations they might confront during a fire and the appropriate responses to those situations. Research shows that mentally rehearsing a situation helps us perform better when we encounter that situation in the physical environment. Similarly, hearing stories acts as a kind of mental flight simulator, preparing us to respond more quickly and effectively.
The listener’s job in this game is quite difficult. Over the course of Newton’s experiment, 120 songs were tapped out. Listeners guessed only 2.5 percent of the songs: 3 out of 120. But here’s what made the result worthy of a dissertation in psychology. Before the listeners guessed the name of the song, Newton asked the tappers to predict the odds that the listeners would guess correctly. They predicted that the odds were 50 percent. The tappers got their message across 1 time in 40, but they thought they were getting their message across 1 time in 2. Why? When a tapper taps, she is hearing the song in her head. Go ahead and try it for yourself—tap out “The Star-Spangled Banner.” It’s impossible to avoid hearing the tune in your head. Meanwhile, the listeners can’t hear that tune—all they can hear is a bunch of disconnected taps, like a kind of bizarre Morse Code. In the experiment, tappers are flabbergasted at how hard the listeners seem to be working to pick up the tune. Isn’t the song obvious? The tappers’ expressions, when a listener guesses “Happy Birthday to You” for “The Star-Spangled Banner,” are priceless: How could you be so stupid? It’s hard to be a tapper. The problem is that tappers have been given knowledge (the song title) that makes it impossible for them to imagine what it’s like to lack that knowledge. When they’re tapping, they can’t imagine what it’s like for the listeners to hear isolated taps rather than a song. This is the Curse of Knowledge. Once we know something, we find it hard to imagine what it was like not to know it. Our knowledge has “cursed” us. And it becomes difficult for us to share our knowledge with others, because we can’t readily re-create our listeners’ state of mind.
Amazingly, when the researchers tried to classify these “less successful” ads, they could classify only 2 percent of them. The surprising lesson of this story: Highly creative ads are more predictable than uncreative ones. It’s like Tolstoy’s quote: “All happy families resemble each other, but each unhappy family is unhappy in its own way.” All creative ads resemble one another, but each loser is uncreative in its own way.
To get to the core, we’ve got to weed out superfluous and tangential elements. But that’s the easy part. The hard part is weeding out ideas that may be really important but just aren’t the most important idea.
Antoine de Saint-Exupéry once offered a definition of engineering elegance: “A designer knows he has achieved perfection not when there is nothing left to add, but when there is nothing left to take away.”
