The accepted definition of creativity is production of something original and useful, and that’s what’s reflected in the tests. There is never one right answer. To be creative requires divergent thinking (generating many unique ideas) and then convergent thinking (combining those ideas into the best result).

The necessity of human ingenuity is undisputed. A recent IBM poll of 1,500 CEOs identified creativity as the No. 1 “leadership competency” of the future. Yet it’s not just about sustaining our nation’s economic growth. All around us are matters of national and international importance that are crying out for creative solutions, from saving the Gulf of Mexico to bringing peace to Afghanistan to delivering health care. Such solutions emerge from a healthy marketplace of ideas, sustained by a populace constantly contributing original ideas and receptive to the ideas of others.

Is this learnable? Well, think of it like basketball. Being tall does help to be a pro basketball player, but the rest of us can still get quite good at the sport through practice. In the same way, there are certain innate features of the brain that make some people naturally prone to divergent thinking. But convergent thinking and focused attention are necessary, too, and those require different neural gifts. Crucially, rapidly shifting between these modes is a top-down function under your mental control. University of New Mexico neuroscientist Rex Jung has concluded that those who diligently practice creative activities learn to recruit their brains’ creative networks quicker and better. A lifetime of consistent habits gradually changes the neurological pattern.

A fine example of this emerged in January of this year, with release of a study by University of Western Ontario neuroscientist Daniel Ansari and Harvard’s Aaron Berkowitz, who studies music cognition. They put Dartmouth music majors and nonmusicians in an fMRI scanner, giving participants a one-handed fiber-optic keyboard to play melodies on. Sometimes melodies were rehearsed; other times they were creatively improvised. During improvisation, the highly trained music majors used their brains in a way the nonmusicians could not: they deactivated their right-temporoparietal junction. Normally, the r-TPJ reads incoming stimuli, sorting the stream for relevance. By turning that off, the musicians blocked out all distraction. They hit an extra gear of concentration, allowing them to work with the notes and create music spontaneously.

Charles Limb of Johns Hopkins has found a similar pattern with jazz musicians, and Austrian researchers observed it with professional dancers visualizing an improvised dance. Ansari and Berkowitz now believe the same is true for orators, comedians, and athletes improvising in games.

The home-game version of this means no longer encouraging kids to spring straight ahead to the right answer. When UGA’s Runco was driving through California one day with his family, his son asked why Sacramento was the state’s capital—why not San Francisco or Los Angeles? Runco turned the question back on him, encouraging him to come up with as many explanations as he could think of.

Preschool children, on average, ask their parents about 100 questions a day. Why, why, why—sometimes parents just wish it’d stop. Tragically, it does stop. By middle school they’ve pretty much stopped asking. It’s no coincidence that this same time is when student motivation and engagement plummet. They didn’t stop asking questions because they lost interest: it’s the other way around. They lost interest because they stopped asking questions.

…highly creative adults tended to grow up in families embodying opposites. Parents encouraged uniqueness, yet provided stability. They were highly responsive to kids’ needs, yet challenged kids to develop skills. This resulted in a sort of adaptability: in times of anxiousness, clear rules could reduce chaos—yet when kids were bored, they could seek change, too. In the space between anxiety and boredom was where creativity flourished.

It’s also true that highly creative adults frequently grew up with hardship. Hardship by itself doesn’t lead to creativity, but it does force kids to become more flexible—and flexibility helps with creativity.

In early childhood, distinct types of free play are associated with high creativity. Preschoolers who spend more time in role-play (acting out characters) have higher measures of creativity: voicing someone else’s point of view helps develop their ability to analyze situations from different perspectives. When playing alone, highly creative first graders may act out strong negative emotions: they’ll be angry, hostile, anguished. The hypothesis is that play is a safe harbor to work through forbidden thoughts and emotions.

In middle childhood, kids sometimes create paracosms—fantasies of entire alternative worlds. Kids revisit their paracosms repeatedly, sometimes for months, and even create languages spoken there. This type of play peaks at age 9 or 10, and it’s a very strong sign of future creativity. A Michigan State University study of MacArthur “genius award” winners found a remarkably high rate of paracosm creation in their childhoods.

From fourth grade on, creativity no longer occurs in a vacuum; researching and studying become an integral part of coming up with useful solutions. But this transition isn’t easy. As school stuffs more complex information into their heads, kids get overloaded, and creativity suffers. When creative children have a supportive teacher—someone tolerant of unconventional answers, occasional disruptions, or detours of curiosity—they tend to excel. When they don’t, they tend to underperform and drop out of high school or don’t finish college at high rates.

They’re quitting because they’re discouraged and bored, not because they’re dark, depressed, anxious, or neurotic. It’s a myth that creative people have these traits. (Those traits actually shut down creativity; they make people less open to experience and less interested in novelty.) Rather, creative people, for the most part, exhibit active moods and positive affect. They’re not particularly happy—contentment is a kind of complacency creative people rarely have. But they’re engaged, motivated, and open to the world.
