Nos écoles d'ingénieurs sont-elles nulles ?

Nouvel épisode dans la guéguerre que se livrent universités et grandes écoles : l'agence d'évaluation de la recherche et de l'enseignement supérieur (AERES) a rendu publique une étude sur "la formation universitaire au métier d'ingénieur". Dans son collimateur, la formation "à la française" dont on nous dit régulièrement que le monde entier nous l'envie. Rien de tel ici.

Le rapport décrit en effet trois modèles. Le premier, américain, qualifié de "modèle de référence" : on y étudie à l'université pour moitié une discipline de spécialité (la mécanique, l'électronique...), l'autre moitié de la formation étant constituée de sciences humaines, de projets de type industriel, éventuellement sous forme de stages, mais pas nécessairement, et, pour finir, de sciences fondamentales. "Il y a évidemment, tout au long du cursus, beaucoup de mathématiques, d'informatique et de physique, mais spécifiques de la spécialité et enseignées au sein de celle-ci et quand elles sont nécessaires", note l'AERES. Deuxième modèle, les cursus en cinq ans, tels que les pratiquent les universités technologiques ou les INSA : "très proches" du modèle américain, ils se caractériseraient par "l'équilibre des composantes, privilégiant la (discipline de) spécialité et les autres sciences de l'ingénieur, et minimisant les prérequis".

Marché multiforme

Vient enfin le troisième "modèle", qui, on l'aura compris, n'a guère la préférence de l'agence. C'est celui des grandes écoles, constitué de deux, voire trois années de préparation à un concours (basé essentiellement sur les maths et la physique), suivies de trois ans de formation en école. Selon le rapport, il y reste "peu de place pour l'enseignement de la spécialité, quelquefois réduite au statut d'option choisie pour la dernière année du cursus." Et l'AERES d'enfoncer le clou, en termes choisis mais assassins : "Souvent critiqué et pas toujours compris à l'étranger, ce modèle a l'incontestable avantage d'attirer vers la formation d'ingénieur des étudiants d'excellent niveau, et plus particulièrement les forts en maths. On lui attribue également les vertus d'une formation par le stress dans les années de classe préparatoire. Il apparaît donc, à ce titre, particulièrement adapté à la formation de certaines catégories d'ingénieurs de haut niveau. Mais il ne couvre pas tous les besoins d'un marché en ingénieurs très multiforme."

Et après avoir déploré que l'université française n'ait pas de formation en ingénierie digne de ce nom, mais une diversité de masters n'obéissant à aucune règle, l'agence appelle de ces voeux un 4e modèle de formation délivrée à l'université qui ressemblerait au 1er modèle. Ingénieurs "à la française", reposez en paix !

Le critère des maths 

Comme on pouvait s'y attendre, les grandes écoles d'ingénieurs n'ont guère goûté cette oraison ! Par l'intermédiaire de la Conférence des directeurs des écoles françaises d'ingénieurs (CDEFI), elles renvoient l'AERES à sa mission : celle d'auditer les formations universitaires existantes, non de proposer des réformes. Elles rappellent aussi que seule la CTI (la Commission des titres d'ingénieurs), composée de représentants du monde académique et du monde professionnel, est autorisée par la loi à habiliter les formations d'ingénieurs. Enfin elles soulignent qu'existent à l'université de très bonnes formations d'ingénieurs : celles qui sont délivrées dans des écoles universitaires et qui ressemblent comme deux gouttes d'eau au modèle 2 (les écoles en cinq ans), lequel n'est pas si éloigné... du modèle 3 !

Il est exact, quoi qu'en dise l'AERES, que les écoles d'ingénieurs en cinq ans ont pour l'immense majorité d'entre elles un cycle préparatoire intégré, dont le programme est calqué sur celui des classes préparatoires. En effet, elles tiennent à pouvoir accueillir dans leur 3e année des élèves issus de ces classes prépa. Mais le vrai débat est ailleurs : pourquoi tant de maths et de sciences fondamentales dans des formations dont la vocation professionnalisante est évidente ? La réponse est connue : en France, les maths servent à sélectionner les meilleurs élèves. Elles ne permettent donc pas forcément de former les meilleurs ingénieurs, mais de s'assurer que les meilleurs deviendront ingénieurs. Ce n'est pas la même chose ! Sont-ils pour autant de mauvais ingénieurs ? Les partisans du modèle "à la française" souligneront que nos ponts ne s'écroulent pas plus qu'ailleurs. Les autres déploreront que nos formations "excellentes-et-que-le-monde-entier-nous-envie", n'ont pas su enrayer le déclin de l'industrie française.

Forget Brainstorming

Brainstorming in a group became popular in 1953 with the publication of a business book, Applied Imagination. But it’s been proven not to work since 1958, when Yale researchers found that the technique actually reduced a team’s creative output: the same number of people generate more and better ideas separately than together. In fact, according to University of Oklahoma professor Michael Mumford, half of the commonly used techniques intended to spur creativity don’t work, or even have a negative impact. As for most commercially available creativity training, Mumford doesn’t mince words: it’s “garbage.” Whether for adults or kids, the worst of these programs focus solely on imagination exercises, expression of feelings, or imagery. They pander to an easy, unchallenging notion that all you have to do is let your natural creativity out of its shell. However, there are some techniques that do boost the creative process:

Don’t tell someone to ‘be creative.’

Such an instruction may just cause people to freeze up. However, according to the University of Georgia’s Mark Runco, there is a suggestion that works: “Do something only you would come up with—that none of your friends or family would think of.” When Runco gives this advice in experiments, he sees the number of creative responses double.

Get moving.

Almost every dimension of cognition improves from 30 minutes of aerobic exercise, and creativity is no exception. The type of exercise doesn’t matter, and the boost lasts for at least two hours afterward. However, there’s a catch: this is the case only for the physically fit. For those who rarely exercise, the fatigue from aerobic activity counteracts the short-term benefits.

Take a break.

Those who study multi-tasking report that you can’t work on two projects simultaneously, but the dynamic is different when you have more than one creative project to complete. In that situation, more projects get completed on time when you allow yourself to switch between them if solutions don’t come immediately. This corroborates surveys showing that professors who set papers aside to incubate ultimately publish more papers. Similarly, preeminent mathematicians usually work on more than one proof at a time.

Reduce screen time.

According to University of Texas professor Elizabeth Vandewater, for every hour a kid regularly watches television, his overall time in creative activities—from fantasy play to arts projects—drops as much as 11 percent. With kids spending about three hours in front of televisions each day, that could be a one-third reduction in creative time—less time to develop a sense of creative self-efficacy through play.

Explore other cultures.

Five experiments by Northwestern’s Adam Galinsky showed that those who have lived abroad outperform others on creativity tasks. Creativity is also higher on average for first- or second-generation immigrants and bilinguals. The theory is that cross-cultural experiences force people to adapt and be more flexible. Just studying another culture can help. In Galinsky’s lab, people were more creative after watching a slide show about China: a 45-minute session increased creativity scores for a week.

Follow a passion.

Rena Subotnik, a researcher with the American Psychological Association, has studied children’s progression into adult creative careers. Kids do best when they are allowed to develop deep passions and pursue them wholeheartedly—at the expense of well-roundedness. “Kids who have deep identification with a field have better discipline and handle setbacks better,” she noted. By contrast, kids given superficial exposure to many activities don’t have the same centeredness to overcome periods of difficulty.

Ditch the suggestion box.

If you want to increase innovation within an organization, one of the first things to do is tear out the suggestion box, advises Isaac Getz, professor at ESCP Europe Business School in Paris. Formalized suggestion protocols, whether a box on the wall, an e-mailed form, or an internal Web site, actually stifle innovation because employees feel that their ideas go into a black hole of bureaucracy. Instead, employees need to be able to put their own ideas into practice. One of the reasons that Toyota’s manufacturing plant in Georgetown, Ky., is so successful is that it implements up to 99 percent of employees’ ideas.

The Creativity Crisis

Back in 1958, Ted Schwarzrock was an 8-year-old third grader when he became one of the “Torrance kids,” a group of nearly 400 Minneapolis children who completed a series of creativity tasks newly designed by professor E. Paul Torrance. Schwarzrock still vividly remembers the moment when a psychologist handed him a fire truck and asked, “How could you improve this toy to make it better and more fun to play with?” He recalls the psychologist being excited by his answers. In fact, the psychologist’s session notes indicate Schwarzrock rattled off 25 improvements, such as adding a removable ladder and springs to the wheels. That wasn’t the only time he impressed the scholars, who judged Schwarzrock to have “unusual visual perspective” and “an ability to synthesize diverse elements into meaningful products.”

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).

In the 50 years since Schwarzrock and the others took their tests, scholars—first led by Torrance, now his colleague, Garnet Millar—have been tracking the children, recording every patent earned, every business founded, every research paper published, and every grant awarded. They tallied the books, dances, radio shows, art exhibitions, software programs, advertising campaigns, hardware innovations, music compositions, public policies (written or implemented), leadership positions, invited lectures, and buildings designed.

Nobody would argue that Torrance’s tasks, which have become the gold standard in creativity assessment, measure creativity perfectly. What’s shocking is how incredibly well Torrance’s creativity index predicted those kids’ creative accomplishments as adults. Those who came up with more good ideas on Torrance’s tasks grew up to be entrepreneurs, inventors, college presidents, authors, doctors, diplomats, and software developers. Jonathan Plucker of Indiana University recently reanalyzed Torrance’s data. The correlation to lifetime creative accomplishment was more than three times stronger for childhood creativity than childhood IQ.

Like intelligence tests, Torrance’s test—a 90-minute series of discrete tasks, administered by a psychologist—has been taken by millions worldwide in 50 languages. Yet there is one crucial difference between IQ and CQ scores. With intelligence, there is a phenomenon called the Flynn effect—each generation, scores go up about 10 points. Enriched environments are making kids smarter. With creativity, a reverse trend has just been identified and is being reported for the first time here: American creativity scores are falling.

Kyung Hee Kim at the College of William & Mary discovered this in May, after analyzing almost 300,000 Torrance scores of children and adults. Kim found creativity scores had been steadily rising, just like IQ scores, until 1990. Since then, creativity scores have consistently inched downward. “It’s very clear, and the decrease is very significant,” Kim says. It is the scores of younger children in America—from kindergarten through sixth grade—for whom the decline is “most serious.”

The potential consequences are sweeping. 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.

It’s too early to determine conclusively why U.S. creativity scores are declining. One likely culprit is the number of hours kids now spend in front of the TV and playing videogames rather than engaging in creative activities. Another is the lack of creativity development in our schools. In effect, it’s left to the luck of the draw who becomes creative: there’s no concerted effort to nurture the creativity of all children.

Around the world, though, other countries are making creativity development a national priority. In 2008 British secondary-school curricula—from science to foreign language—was revamped to emphasize idea generation, and pilot programs have begun using Torrance’s test to assess their progress. The European Union designated 2009 as the European Year of Creativity and Innovation, holding conferences on the neuroscience of creativity, financing teacher training, and instituting problem-based learning programs—curricula driven by real-world inquiry—for both children and adults. In China there has been widespread education reform to extinguish the drill-and-kill teaching style. Instead, Chinese schools are also adopting a problem-based learning approach.

Plucker recently toured a number of such schools in Shanghai and Beijing. He was amazed by a boy who, for a class science project, rigged a tracking device for his moped with parts from a cell phone. When faculty of a major Chinese university asked Plucker to identify trends in American education, he described our focus on standardized curriculum, rote memorization, and nationalized testing. “After my answer was translated, they just started laughing out loud,” Plucker says. “They said, ‘You’re racing toward our old model. But we’re racing toward your model, as fast as we can.’ ”

Overwhelmed by curriculum standards, American teachers warn there’s no room in the day for a creativity class. Kids are fortunate if they get an art class once or twice a week. But to scientists, this is a non sequitur, borne out of what University of Georgia’s Mark Runco calls “art bias.” The age-old belief that the arts have a special claim to creativity is unfounded. When scholars gave creativity tasks to both engineering majors and music majors, their scores laid down on an identical spectrum, with the same high averages and standard deviations. Inside their brains, the same thing was happening—ideas were being generated and evaluated on the fly.

Researchers say creativity should be taken out of the art room and put into homeroom. The argument that we can’t teach creativity because kids already have too much to learn is a false trade-off. Creativity isn’t about freedom from concrete facts. Rather, fact-finding and deep research are vital stages in the creative process. Scholars argue that current curriculum standards can still be met, if taught in a different way.

To understand exactly what should be done requires first understanding the new story emerging from neuroscience. The lore of pop psychology is that creativity occurs on the right side of the brain. But we now know that if you tried to be creative using only the right side of your brain, it’d be like living with ideas perpetually at the tip of your tongue, just beyond reach.

When you try to solve a problem, you begin by concentrating on obvious facts and familiar solutions, to see if the answer lies there. This is a mostly left-brain stage of attack. If the answer doesn’t come, the right and left hemispheres of the brain activate together. Neural networks on the right side scan remote memories that could be vaguely relevant. A wide range of distant information that is normally tuned out becomes available to the left hemisphere, which searches for unseen patterns, alternative meanings, and high-level abstractions.

Having glimpsed such a connection, the left brain must quickly lock in on it before it escapes. The attention system must radically reverse gears, going from defocused attention to extremely focused attention. In a flash, the brain pulls together these disparate shreds of thought and binds them into a new single idea that enters consciousness. This is the “aha!” moment of insight, often followed by a spark of pleasure as the brain recognizes the novelty of what it’s come up with.

Now the brain must evaluate the idea it just generated. Is it worth pursuing? Creativity requires constant shifting, blender pulses of both divergent thinking and convergent thinking, to combine new information with old and forgotten ideas. Highly creative people are very good at marshaling their brains into bilateral mode, and the more creative they are, the more they dual-activate.

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 good news is that creativity training that aligns with the new science works surprisingly well. The University of Oklahoma, the University of Georgia, and Taiwan’s National Chengchi University each independently conducted a large-scale analysis of such programs. All three teams of scholars concluded that creativity training can have a strong effect. “Creativity can be taught,” says James C. Kaufman, professor at California State University, San Bernardino.

What’s common about successful programs is they alternate maximum divergent thinking with bouts of intense convergent thinking, through several stages. Real improvement doesn’t happen in a weekend workshop. But when applied to the everyday process of work or school, brain function improves.

So what does this mean for America’s standards-obsessed schools? The key is in how kids work through the vast catalog of information. Consider the National Inventors Hall of Fame School, a new public middle school in Akron, Ohio. Mindful of Ohio’s curriculum requirements, the school’s teachers came up with a project for the fifth graders: figure out how to reduce the noise in the library. Its windows faced a public space and, even when closed, let through too much noise. The students had four weeks to design proposals.

Working in small teams, the fifth graders first engaged in what creativity theorist Donald Treffinger describes as fact-finding. How does sound travel through materials? What materials reduce noise the most? Then, problem-finding—anticipating all potential pitfalls so their designs are more likely to work. Next, idea-finding: generate as many ideas as possible. Drapes, plants, or large kites hung from the ceiling would all baffle sound. Or, instead of reducing the sound, maybe mask it by playing the sound of a gentle waterfall? A proposal for double-paned glass evolved into an idea to fill the space between panes with water. Next, solution-finding: which ideas were the most effective, cheapest, and aesthetically pleasing? Fiberglass absorbed sound the best but wouldn’t be safe. Would an aquarium with fish be easier than water-filled panes?

Then teams developed a plan of action. They built scale models and chose fabric samples. They realized they’d need to persuade a janitor to care for the plants and fish during vacation. Teams persuaded others to support them—sometimes so well, teams decided to combine projects. Finally, they presented designs to teachers, parents, and Jim West, inventor of the electric microphone.

Along the way, kids demonstrated the very definition of creativity: alternating between divergent and convergent thinking, they arrived at original and useful ideas. And they’d unwittingly mastered Ohio’s required fifth-grade curriculum—from understanding sound waves to per-unit cost calculations to the art of persuasive writing. “You never see our kids saying, ‘I’ll never use this so I don’t need to learn it,’ ” says school administrator Maryann Wolowiec. “Instead, kids ask, ‘Do we have to leave school now?’ ” Two weeks ago, when the school received its results on the state’s achievement test, principal Traci Buckner was moved to tears. The raw scores indicate that, in its first year, the school has already become one of the top three schools in Akron, despite having open enrollment by lottery and 42 percent of its students living in poverty.

With as much as three fourths of each day spent in project-based learning, principal Buckner and her team actually work through required curricula, carefully figuring out how kids can learn it through the steps of Treffinger’s Creative Problem-Solving method and other creativity pedagogies. “The creative problem-solving program has the highest success in increasing children’s creativity,” observed William & Mary’s Kim.

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.

Having studied the childhoods of highly creative people for decades, Claremont Graduate University’s Mihaly Csikszentmihalyi and University of Northern Iowa’s Gary G. Gute found 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.

The new view is that creativity is part of normal brain function. Some scholars go further, arguing that lack of creativity—not having loads of it—is the real risk factor. In his research, Runco asks college students, “Think of all the things that could interfere with graduating from college.” Then he instructs them to pick one of those items and to come up with as many solutions for that problem as possible. This is a classic divergent-convergent creativity challenge. A subset of respondents, like the proverbial Murphy, quickly list every imaginable way things can go wrong. But they demonstrate a complete lack of flexibility in finding creative solutions. It’s this inability to conceive of alternative approaches that leads to despair. Runco’s two questions predict suicide ideation—even when controlling for preexisting levels of depression and anxiety.

In Runco’s subsequent research, those who do better in both problem-finding and problem-solving have better relationships. They are more able to handle stress and overcome the bumps life throws in their way. A similar study of 1,500 middle schoolers found that those high in creative self-efficacy had more confidence about their future and ability to succeed. They were sure that their ability to come up with alternatives would aid them, no matter what problems would arise.

When he was 30 years old, Ted Schwarzrock was looking for an alternative. He was hardly on track to becoming the prototype of Torrance’s longitudinal study. He wasn’t artistic when young, and his family didn’t recognize his creativity or nurture it. The son of a dentist and a speech pathologist, he had been pushed into medical school, where he felt stifled and commonly had run-ins with professors and bosses. But eventually, he found a way to combine his creativity and medical expertise: inventing new medical technologies.

Today, Schwarzrock is independently wealthy—he founded and sold three medical-products companies and was a partner in three more. His innovations in health care have been wide ranging, from a portable respiratory oxygen device to skin-absorbing anti-inflammatories to insights into how bacteria become antibiotic-resistant. His latest project could bring down the cost of spine-surgery implants 50 percent. “As a child, I never had an identity as a ‘creative person,’ ” Schwarzrock recalls. “But now that I know, it helps explain a lot of what I felt and went through.”

Creativity has always been prized in American society, but it’s never really been understood. While our creativity scores decline unchecked, the current national strategy for creativity consists of little more than praying for a Greek muse to drop by our houses. The problems we face now, and in the future, simply demand that we do more than just hope for inspiration to strike. Fortunately, the science can help: we know the steps to lead that elusive muse right to our doors.

Charting Creativity: Signposts of a Hazy Territory


Grab a timer and set it for one minute. Now list as many creative uses for a brick as you can imagine. Go.

The question is part of a classic test for creativity, a quality that scientists are trying for the first time to track in the brain.

They hope to figure out precisely which biochemicals, electrical impulses and regions were used when, say, Picasso painted “Guernica,” or Louise Nevelson assembled her wooden sculptures. Using M.R.I. technology, researchers are monitoring what goes on inside a person’s brain while he or she engages in a creative task.

Yet the images of signals flashing across frontal lobes have pushed scientists to re-examine the very way creativity is measured in a laboratory.

“Creativity is kind of like pornography — you know it when you see it,” said Rex Jung, a research scientist at the Mind Research Network in Albuquerque. Dr. Jung, an assistant research professor in the department of neurosurgery at the University of New Mexico, said his team was doing the first systematic research on the neurology of the creative process, including its relationship to personality and intelligence.

Like many researchers over the past 30 years or so, Dr. Jung has relied on a common definition of creativity: the ability to combine novelty and usefulness in a particular social context.

As the study of creativity has expanded to include brain neurology, however, some scientists question whether this standard definition and the tests for it still make sense. John Kounios, a psychologist at Drexel University, argues that the standard “has outlived its usefulness.”

“Creativity is a complex concept; it’s not a single thing,” he said, adding that brain researchers needed to break it down into its component parts. Dr. Kounios, who studies the neural basis of insight, defines creativity as the ability to restructure one’s understanding of a situation in a nonobvious way.

Everyone agrees that no single measure for creativity exists. While I.Q. tests, though controversial, are still considered a reliable test of at least a certain kind of intelligence, there is no equivalent when it comes to creativity — no Creativity Quotient, or C.Q.

Dr. Jung’s lab uses a combination of measures as proxies for creativity. One is the Creativity Achievement Questionnaire, which asks people to report their own aptitude in 10 fields, including the visual arts, music, creative writing, architecture, humor and scientific discovery.


Another is a test for “divergent thinking,” a classic measure developed by the pioneering psychologist J. P. Guilford. Here a person is asked to come up with “new and useful” functions for a familiar object, like a brick, a pencil or a sheet of paper.

Dr. Jung’s team also presents subjects with weird situations. Imagine people could instantly change their sex, or imagine clouds had strings; what would be the implications?

In another assessment, a subject is asked to draw the taste of chocolate or write a caption for a humorous cartoon, as is done in The New Yorker magazine’s weekly contest. “Humor is an important part of creativity,” Dr. Jung said.

The responses are used to generate what Dr. Jung calls a “Composite Creativity Index.”

Dr. Jung’s tests are based on ones created by Robert J. Sternberg, one of the country’s pre-eminent intelligence researchers and the man partly responsible for the standard definition. Dr. Sternberg uses similar types of tests at Tufts University, where he investigates how people develop and master skills. He explained that his team asked subjects to think through what would have happened if, say, Rosa Parks had given up her seat for a white woman when that Montgomery bus driver told her to move to the back, or if Hitler had won World War II. They might also present them with a fanciful headline, like “The End of MTV.”

As for Dr. Jung, his research has produced some surprising results. One study of 65 subjects suggests that creativity prefers to take a slower, more meandering path than intelligence.

“The brain appears to be an efficient superhighway that gets you from Point A to Point B” when it comes to intelligence, Dr. Jung explained. “But in the regions of the brain related to creativity, there appears to be lots of little side roads with interesting detours, and meandering little byways.”

Although intelligence and skill are generally associated with the fast and efficient firing of neurons, subjects who tested high in creativity had thinner white matter and connecting axons that have the effect of slowing nerve traffic in the brain. This slowdown in the left frontal cortex, a region where emotional and cognitive abilities are integrated, Dr. Jung suggested, “might allow for the linkage of more disparate ideas, more novelty and more creativity.”

Dr. Kounios, of Drexel, said that Dr. Jung was doing original and interesting work, but he maintained that trying to find a correlation between creativity and a single area of the brain is an “old-fashioned approach.”


“Creativity is a collection of different processes that work in different areas of the brain,” Dr. Kounios said, so the creative act must be broken down into tiny pieces. He also rejects utility as part of the definition, arguing that there can be brilliant and creative failures — what he calls near misses.

Last year he and Mark Beeman, a psychologist at Northwestern University, published a paper on what he calls the “Aha! moment,” the sudden insight that solves a problem, reinterprets a situation or explains a joke. In their test, they used simple word puzzles that could be solved either with an instant creative insight or a quick analysis.

For example, here are three words: crab, pine and sauce.

Now, think of a single word that could be combined with each of the three to form a familiar term.

(Time’s up. The answer is “apple.”)

About half the subjects came up with a solution by methodically thinking through possibilities; with the other half, the answer popped into their minds.

A lot of different areas of the brain are involved in devising a solution, no matter which process is used, but during the Aha! moment, there is a burst of high-frequency activity in the right temporal lobe, Dr. Kounios said. What’s more, he said, he and Dr. Beeman could predict in advance which process a subject would use. They watched the brains of systematic problem solvers prepare by paying closer attention to the screen before the words appeared. Their visual cortices were on high alert.

The brains of those who got a flash of creative insight, by contrast, prepared by automatically shutting down activity in the visual cortex for an instant — the equivalent of closing your eyes to block out distractions so that you can concentrate better. In this case, Dr. Kounios said that the brain was “cutting out other sensory input and boosting the signal-to-noise ratio” to retrieve the answer from the subconscious.

According to Kenneth Heilman, a neurologist at the University of Florida and the author of “Creativity and the Brain” (2005), creativity not only involves coming up with something new, but also with shutting down the brain’s habitual response, or letting go of conventional solutions.

Risk taking and addictive behavior should also be measured, since both traits play a role in creativity, he said.

There may be, for example, a dampening of norepinephrine, the neurotransmitter that sets off the fight-or-flight alarm. That’s why creative connections often occur when people are most peaceful — relaxing under a tree, like Isaac Newton, or in a dream state, like Coleridge when he thought up “Kubla Khan.”

John Gabrieli, a professor of cognitive neuroscience at the Massachusetts Institute of Technology, cautions that there is always a gap between what happens in the lab and the real world: “It seems that to be creative is to be something we don’t have a test for.”

A Campus Where Unlearning Is First


CAIRO — When Rafik Gindy graduated from high school, he knew he wanted to become an engineer. So he enrolled at the American University in Cairo and prepared to immerse himself in math and science.

Mr. Gindy knew what he wanted to be, but did not exactly know who he was. That was what the university wanted him to think about, in a class called “The Human Quest: Exploring the Big Questions.”

“I thought identity was just your name, your culture, but now I know it’s really complex,” said Mr. Gindy, a slender freshman who shook his head at that revelation.

Who am I?

What does it mean to be human?

These are the kinds of questions posed to undergraduate students entering this 90-year-old university during what the president, David D. Arnold, called a first year of “disorientation.” During disorientation, the students — 85 percent of them Egyptians — are taught to learn in ways quite at odds with the traditional method of teaching in this country, where instructors lecture, students memorize and tests are exercises in regurgitation.

“It’s different here because there is room for people to express themselves,” said Manar Mohsen, a junior majoring in political science and journalism. “It is not that simple outside, where it is more about conformity.

Egypt, like much of the Arab world, demands conformity in many corners of life. Education is based on the concept of rote learning, and creativity in the classroom is often discouraged. Students at Cairo University say they memorize and recite, never analyze and hypothesize.

So the idea of a liberal arts education aimed at developing critical thinking skills is often new to the students. That can make for a difficult transition. Plagiarism is often a problem at both the undergraduate and graduate levels, officials here said, because the students — accustomed to rote learning — see nothing wrong with spitting back someone else’s work and have never been held to rigorous academic standards.

“For a lot of the kids here, the idea that you are supposed to have your own ideas is a novelty,” said Lisa Anderson, the university provost who is on leave from Columbia University. “There was nothing in their previous education that would have exposed them to these standards.”

American University is a private, elite school, although university officials sometimes recoil at the elite label. Yet, the school is expensive and so is generally out of reach for all but the wealthiest families and a handful of scholarship students. Tuition and fees for Egyptian students run about $19,600 a year, a princely sum in a country where about half the population lives on about $2 a day.

The campus exudes affluence. Students joke about the “Gucci corridor,” a spot where well-coiffed students gather each afternoon. There is no cafeteria, only expensive fast-food stands.

“We are all rich and spoiled,” said one student, upset that more of her classmates were not more politically aware. But in some respects, the elite label is a strength. American University plays a central role as a sort of intellectual boot camp for young people who will become leaders in government and the economy.

“If we teach the elite to be good citizens, that’s not a bad thing,” Ms. Anderson said.

Nabil Fahmy, the former longtime ambassador to the United States, said that over his nine years in Washington, at least 40 percent of the embassy staff was made up of American University graduates, as was he.

The university was founded in 1919 by a group of Presbyterian missionaries. Unlike the satellite campuses of prestigious American universities in oil-rich Persian Gulf states, it is quite homegrown and often reflects the community around it.

The university was located originally in Tahrir Square, in the center of Cairo, a hyper-urban landscape where the air is thick, the din overwhelming and the mosaic of Egyptian life on every corner. That was part of the university’s appeal.

But over the years it has grown, and now serves 5,000 undergraduates on an architecturally inspiring, if geographically isolated, $400 million, 260-acre campus in a suburb called New Cairo. Instead of urban grime the campus is surrounded by villas and developments with names like Golden Heights.


The location redefined the university just as the university was beginning to redefine itself, as a first-rate university rather than a finishing school for Egypt’s elite. But as the school has grown, so has a conflict within the university itself: can it change its mission while retaining its liberal arts core and preserving classes like the Big Questions?

“We are moving more and more into professional schools, like business, engineering, sciences,” said Mr. Fahmy, the former ambassador, who is the founding dean of a new school of global affairs and public policy.

“The challenge we have now is we have moved from a small college that thought it was a university, to a university that has to change its thinking from being a small college,” he said, defining a view that is anathema to some others on campus.

There are other pressures, too, coming from a society that holds engineers in such high esteem that the profession is also a courtesy title, like doctor.

“The humanities in general, and philosophy specifically, are seen as either frivolous or, at the very least, not financially prudent, by many of the very people who seek what makes A.U.C. unique,” said Nathaniel Bowditch, an assistant professor of philosophy. Dr. Bowditch argued that “learning how to think rather than what to think prepares a person for all professions,” and that without that “the academy becomes nothing more than a trade school.”

For now, the university leadership says it remains committed to its core mission, and will continue to ensure that incoming Egyptian students relearn how to learn, officials here said. “We want our students to be imaginative in their fields,” Ms. Anderson said.

So for the time being, at least, the Big Questions class remains safe, which seems to suit the students just fine.

“I took the course because my brother took it two years ago,” said Mr. Gindy, the freshman construction engineering major. “I like how it explained things we never knew, like how the world began.”

School kills creativity

Sir Ken Robinson makes an entertaining and profoundly moving case for creating an education system that nurtures (rather than undermines) creativity.
