Made to Stick (2 page)

The broad question, then, is how do you design an idea that sticks?

A few years ago the two of us—brothers Chip and Dan—realized that both of us had been studying how ideas stick for about ten years. Our expertise came from very different fields, but we had zeroed in on the same question: Why do some ideas succeed while others fail?

Dan had developed a passion for education. He co-founded a start-up publishing company called Thinkwell that asked a somewhat heretical question: If you were going to build a textbook from scratch, using video and technology instead of text, how would you do it? As the editor in chief of Thinkwell, Dan had to work with his team to determine the best ways to teach subjects like economics, biology, calculus, and physics. He had an opportunity to work with some of the most effective and best-loved professors in the country: the calculus teacher who was also a stand-up comic; the biology teacher who was named national Teacher of the Year; the economics teacher who was also a chaplain and a playwright. Essentially, Dan enjoyed a crash course in what makes great teachers great. And he found that, while
each teacher had a unique style, collectively their instructional
methodologies
were almost identical.

Chip, as a professor at Stanford University, had spent about ten years asking why bad ideas sometimes won out in the social marketplace of ideas. How could a false idea displace a true one? And what made some ideas more viral than others? As an entry point into these topics, he dove into the realm of “naturally sticky” ideas such as urban legends and conspiracy theories. Over the years, he’s become uncomfortably familiar with some of the most repulsive and absurd tales in the annals of ideas. He’s heard them all. Here’s a very small sampler:

• The Kentucky Fried Rat. Really, any tale that involves rats and fast food is on fertile ground.
  

• Coca-Cola rots your bones. This fear is big in Japan, but so far the country hasn’t experienced an epidemic of gelatinous teenagers.
  

• If you flash your brights at a car whose headlights are off, you will be shot by a gang member.
  

• The Great Wall of China is the only man-made object that is visible from space. (The Wall is really long but not very wide. Think about it: If the Wall were visible, then any interstate highway would also be visible, and maybe a few Wal-Mart superstores as well.)
  

• You use only 10 percent of your brain. (If this were true, it would certainly make brain damage a lot less worrisome.)
  

Chip, along with his students, has spent hundreds of hours collecting, coding, and analyzing naturally sticky ideas: urban legends, wartime rumors, proverbs, conspiracy theories, and jokes. Urban legends are false, but many naturally sticky ideas are true. 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.

In studying naturally sticky ideas, both trivial and profound, Chip has conducted more than forty experiments with more than 1,700 participants on topics such as:

• Why Nostradamus’s prophecies are still read after 400 years
  

• Why
  Chicken Soup for the Soul
  stories are inspirational
  

• Why ineffective folk remedies persist
  

A few years ago, he started teaching a course at Stanford called “How to Make Ideas Stick.” The premise of the course was that if we understood what made ideas naturally sticky we might be better at making our own messages stick. During the past few years he has taught this topic to a few hundred students bound for careers as managers, public-policy analysts, journalists, designers, and film directors.

To complete the story of the Brothers Heath, in 2004 it dawned on us that we had been approaching the same problem from different angles. Chip had researched and taught what made ideas stick. Dan had tried to figure out pragmatic ways to make ideas stick. Chip had compared the success of different urban legends and stories. Dan had compared the success of different math and government lessons. Chip was the researcher and the teacher. Dan was the practitioner and the writer. (And we knew that we could make our parents happy by spending more quality time together.)

We wanted to take apart sticky ideas—both natural and created—and figure out what made them stick. What makes urban legends so compelling? Why do some chemistry lessons work better than others? Why does virtually every society circulate a set of proverbs? Why do some political ideas circulate widely while others fall short?

In short, we were looking to understand what sticks. We adopted
the “what sticks” terminology from one of our favorite authors, Malcolm Gladwell. In 2000, Gladwell wrote a brilliant book called
The Tipping Point
, which examined the forces that cause social phenomena to “tip,” or make the leap from small groups to big groups, the way contagious diseases spread rapidly once they infect a certain critical mass of people. Why did Hush Puppies experience a rebirth? Why did crime rates abruptly plummet in New York City? Why did the book
Divine Secrets of the Ya-Ya Sisterhood
catch on?

The Tipping Point
has three sections. The first addresses the need to get the right people, and the third addresses the need for the right context. The middle section of the book, “The Stickiness Factor,” argues that innovations are more likely to tip when they’re sticky. When
The Tipping Point
was published, Chip realized that “stickiness” was the perfect word for the attribute that he was chasing with his research into the marketplace of ideas.

This book is a complement to
The Tipping Point
in the sense that we will identify
the traits
that make ideas sticky, a subject that was beyond the scope of Gladwell’s book. Gladwell was interested in what makes social epidemics epidemic. Our interest is in how effective ideas are constructed—what makes some ideas stick and others disappear. So, while our focus will veer away from
The Tipping Point
’s turf, we want to pay tribute to Gladwell for the word “stickiness.” It stuck.

In the 1960s and 1970s, the tradition of Halloween trick-or-treating came under attack. Rumors circulated about Halloween sadists who put razor blades in apples and booby-trapped pieces of candy. The rumors affected the Halloween tradition nationwide. Parents carefully examined their children’s candy bags. Schools opened their doors at night so that kids could trick-or-treat in a safe environment. Hospitals volunteered to X-ray candy bags.

In 1985, an ABC News poll showed that 60 percent of parents worried that their children might be victimized. To this day, many parents warn their children not to eat any snacks that aren’t prepackaged. This is a sad story: a family holiday sullied by bad people who, inexplicably, wish to harm children. But in 1985 the story took a strange twist. Researchers discovered something shocking about the candy-tampering epidemic: It was a myth.

The researchers, sociologists Joel Best and Gerald Horiuchi, studied every reported Halloween incident since 1958. They found no instances where strangers caused children life-threatening harm on Halloween by tampering with their candy.

Two children did die on Halloween, but their deaths weren’t caused by strangers. A five-year-old boy found his uncle’s heroin stash and overdosed. His relatives initially tried to cover their tracks by sprinkling heroin on his candy. In another case, a father, hoping to collect on an insurance settlement, caused the death of his own son by contaminating his candy with cyanide.

In other words, the best social science evidence reveals that taking candy from strangers is perfectly okay. It’s your family you should worry about.

The candy-tampering story has changed the behavior of millions of parents over the past thirty years. Sadly, it has made neighbors suspicious of neighbors. It has even changed the laws of this country: Both California and New Jersey passed laws that carry special penalties for candy-tamperers. Why was this idea so successful?

The Halloween-candy story is, in a sense, the evil twin of the CSPI story.

Both stories highlighted an unexpected danger in a common activity: eating Halloween candy and eating movie popcorn. Both stories
called for simple action: examining your child’s candy and avoiding movie popcorn. Both made use of vivid, concrete images that cling easily to memory: an apple with a buried razor blade and a table full of greasy foods. And both stories tapped into emotion: fear in the case of Halloween candy and disgust in the case of movie popcorn.

The Kidney Heist, too, shares many of these traits. A highly
unexpected
outcome: a guy who stops for a drink and ends up one kidney short of a pair. A lot of
concrete
details: the ice-filled bathtub, the weird tube protruding from the lower back.
Emotion:
fear, disgust, suspicion.

We began to see the same themes, the same attributes, reflected in a wide range of successful ideas. What we found based on Chip’s research—and by reviewing the research of dozens of folklorists, psychologists, educational researchers, political scientists, and proverb-hunters—was that sticky ideas shared certain key traits. There is no “formula” for a sticky idea—we don’t want to overstate the case. But sticky ideas do draw from a common set of traits, which make them more likely to succeed.

It’s like discussing the attributes of a great basketball player. You can be pretty sure that any great player has some subset of traits like height, speed, agility, power, and court sense. But you don’t need all of these traits in order to be great: Some great guards are five feet ten and scrawny. And having all the traits doesn’t guarantee greatness: No doubt there are plenty of slow, clumsy seven-footers. It’s clear, though, that if you’re on the neighborhood court, choosing your team from among strangers, you should probably take a gamble on the seven-foot dude.

Ideas work in much the same way. One skill we can learn is the ability to
spot
ideas that have “natural talent,” like the seven-foot stranger. Later in the book, we’ll discuss Subway’s advertising campaign that focused on Jared, an obese college student who lost more than 200 pounds by eating Subway sandwiches every day. The campaign
was a huge success. And it wasn’t created by a Madison Avenue advertising agency; it started with a single store owner who had the good sense to spot an amazing story.

But here’s where our basketball analogy breaks down: In the world of ideas, we can genetically engineer our players. We can
create
ideas with an eye to maximizing their stickiness.

As we pored over hundreds of sticky ideas, we saw, over and over, the same six principles at work.

How do we find the essential core of our ideas? A successful defense lawyer says, “If you argue ten points, even if each is a good point, when they get back to the jury room they won’t remember any.” To strip an idea down to its core, we must be masters of exclusion. We must relentlessly prioritize. Saying something short is not the mission—sound bites are not the ideal. 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.

How do we get our audience to pay attention to our ideas, and how do we maintain their interest when we need time to get the ideas across? 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. But surprise doesn’t last. For our idea to endure, we must generate
interest
and
curiosity
. How do you keep students engaged during the forty-eighth history class of the year? We can engage people’s curiosity over a long period of time by systematically “opening gaps” in their knowledge—and then filling those gaps.

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 make people believe our ideas? When the former surgeon general C. Everett Koop talks about a public-health issue, most people accept his ideas without skepticism. But in most day-to-day situations we don’t enjoy this authority. Sticky ideas have to carry their own credentials. We need ways to help people test our ideas for themselves—a “try before you buy” philosophy for the world of ideas. When we’re trying to build a case for something, most of us instinctively grasp for hard numbers. But in many cases this is exactly the wrong approach. In the sole U.S. presidential debate in 1980 between Ronald Reagan and Jimmy Carter, Reagan could have cited innumerable statistics demonstrating the sluggishness of the economy. Instead, he asked a simple question that allowed voters to test for themselves: “Before you vote, ask yourself if you are better off today than you were four years ago.”

How do we get people to care about our ideas? We make them
feel
something. In the case of movie popcorn, we make them feel disgusted
by its unhealthiness. The statistic “37 grams” doesn’t elicit any emotions. Research shows that people are more likely to make a charitable gift to a single needy individual than to an entire impoverished region. We are wired to feel things for people, not for abstractions. Sometimes the hard part is finding the right emotion to harness. For instance, it’s difficult to get teenagers to quit smoking by instilling in them a fear of the consequences, but it’s easier to get them to quit by tapping into their resentment of the duplicity of Big Tobacco.
