All Cultures Are Not Equal

By DAVID BROOKS

Let's say you are an 18-year-old kid with a really big brain. You're trying to figure out which field of study you should devote your life to, so you can understand the forces that will be shaping history for decades to come.

Go into the field that barely exists: cultural geography. Study why and how people cluster, why certain national traits endure over centuries, why certain cultures embrace technology and economic growth and others resist them.

This is the line of inquiry that is now impolite to pursue. The gospel of multiculturalism preaches that all groups and cultures are equally wonderful. There are a certain number of close-minded thugs, especially on university campuses, who accuse anybody who asks intelligent questions about groups and enduring traits of being racist or sexist. The economists and scientists tend to assume that material factors drive history - resources and brain chemistry - because that's what they can measure and count.

But none of this helps explain a crucial feature of our time: while global economies are converging, cultures are diverging, and the widening cultural differences are leading us into a period of conflict, inequality and segmentation.

Not long ago, people said that globalization and the revolution in communications technology would bring us all together. But the opposite is true. People are taking advantage of freedom and technology to create new groups and cultural zones. Old national identities and behavior patterns are proving surprisingly durable. People are moving into self-segregating communities with people like themselves, and building invisible and sometimes visible barriers to keep strangers out.

If you look just around the United States you find amazing cultural segmentation. We in America have been "globalized" (meaning economically integrated) for centuries, and yet far from converging into some homogeneous culture, we are actually diverging into lifestyle segments. The music, news, magazine and television markets have all segmented, so there are fewer cultural unifiers like Life magazine or Walter Cronkite.

Forty-million Americans move every year, and they generally move in with people like themselves, so as the late James Chapin used to say, every place becomes more like itself. Crunchy places like Boulder attract crunchy types and become crunchier. Conservative places like suburban Georgia attract conservatives and become more so.

Not long ago, many people worked on farms or in factories, so they had similar lifestyles. But now the economy rewards specialization, so workplaces and lifestyles diverge. The military and civilian cultures diverge. In the political world, Democrats and Republicans seem to live on different planets.

Meanwhile, if you look around the world you see how often events are driven by groups that reject the globalized culture. Islamic extremists reject the modern cultures of Europe, and have created a hyperaggressive fantasy version of traditional Islamic purity. In a much different and less violent way, some American Jews have moved to Hebron and become hyper-Zionists.

From Africa to Seattle, religiously orthodox students reject what they see as the amoral mainstream culture, and carve out defiant revival movements. From Rome to Oregon, antiglobalization types create their own subcultures.

The members of these and many other groups didn't inherit their identities. They took advantage of modernity, affluence and freedom to become practitioners of a do-it-yourself tribalism. They are part of a great reshuffling of identities, and the creation of new, often more rigid groupings. They have the zeal of converts.

Meanwhile, transnational dreams like European unification and Arab unity falter, and behavior patterns across nations diverge. For example, fertility rates between countries like the U.S. and Canada are diverging. Work habits between the U.S. and Europe are diverging. Global inequality widens as some nations with certain cultural traits prosper and others with other traits don't.

People like Max Weber, Edward Banfield, Samuel Huntington, Lawrence Harrison and Thomas Sowell have given us an inkling of how to think about this stuff, but for the most part, this is open ground.

If you are 18 and you've got that big brain, the whole field of cultural geography is waiting for you.

The Male Condition

By SIMON BARON-COHEN
Cambridge, England

TWO big scientific debates have attracted a lot of attention over the past year. One concerns the causes of autism, while the other addresses differences in scientific aptitude between the sexes. At the risk of adding fuel to both fires, I submit that these two lines of inquiry have a great deal in common. By studying the differences between male and female brains, we can generate significant insights into the mystery of autism.

So was Lawrence Summers, the president of Harvard, right when he remarked that women were innately less suited than men to be top-level scientists? Judging from current research, he was and he wasn't. It's true that scientists have documented psychological and physiological differences between male and female brains. But Mr. Summers was wrong to imply that these differences render any individual woman less capable than any individual man of becoming a top-level scientist.

In fact, the differences that show up in brain research reflect averages, meaning that they emerge only when you study groups of males and females and compare the two groups' averages on particular psychological tests or physiological measures. The evidence to date tells us nothing about individuals - which means that if you are a woman, there is no evidence to suggest that you could not become a Nobel laureate in your chosen area of scientific inquiry. A good scientist is a good scientist regardless of sex.

Nonetheless, with brain scanning, we can discern physiological differences between the average male and the average female brain. For example, the average man's cerebrum (the area in the front of the brain concerned with higher thinking) is 9 percent larger than the average woman's. Similar, though less distinct, overgrowth is found in all the lobes of the male brain. On average, men also have a larger amygdala (an almond shaped structure in the center of the brain involved in processing fear and emotion), and more nerve cells. Quite how these differences in size affect function, if at all, is not yet known.

In women, meanwhile, the connective tissue that allows communication between the two hemispheres of the brain tends to be thicker, perhaps facilitating interchange. This may explain why one study from Yale found that when performing language tasks, women are likely to activate both hemispheres, whereas males (on average) activate only the left hemisphere.

Psychological tests also reveal patterns of sex difference. On average, males finish faster and score higher than females on a test that requires the taker to visualize an object's appearance after it is rotated in three dimensions. The same is true for map-reading tests, and for embedded-figures tests, which ask subjects to find a component shape hidden within a larger design. Males are over-represented in the top percentiles on college-level math tests and tend to score higher on mechanics tests than females do. Females, on the other hand, average higher scores than males on tests of emotion recognition, social sensitivity and language ability.

Many of these sex differences are seen in adults, which might lead to the conclusion that all they reflect are differences in socialization and experience. But some differences are also seen extremely early in development, which may suggest that biology also plays a role. For example, girls tend to talk earlier than boys, and in the second year of life their vocabularies grow at a faster rate. One-year-old girls also make more eye contact than boys of their age.

In my work I have summarized these differences by saying that males on average have a stronger drive to systemize, and females to empathize. Systemizing involves identifying the laws that govern how a system works. Once you know the laws, you can control the system or predict its behavior. Empathizing, on the other hand, involves recognizing what another person may be feeling or thinking, and responding to those feelings with an appropriate emotion of one's own.

Our research team in Cambridge administered questionnaires on which men and women could report their level of interest in these two aspects of the world - one involving systems, the other involving other people's feelings. Three types of people were revealed through our study: one for whom empathy is stronger than systemizing (Type E brains); another for whom systemizing is stronger than empathy (Type S brains); and a third for whom empathy and systemizing are equally strong (Type B brains). As one might predict, more women (44 percent) have Type E brains than men (17 percent), while more men have Type S brains (54 percent) than women (17 percent).

What of Mr. Summers's other claim, that such sex differences are innate? We know that culture plays a role in the divergence of the sexes, but so does biology. For example, on the first day of life, male and female newborns pay attention to different things. On average, at 24 hours old, more male infants will look at a mechanical mobile suspended above them, whereas more female infants will look at a human face.

It has also been found that the amount of prenatal testosterone, which is produced by the fetus and measurable in the amniotic fluid in which the baby is bathed in the womb, predicts how sociable a child will be. The higher the level of prenatal testosterone, the less eye contact the child will make as a toddler, and the slower the child will develop language. That is connected to the role of fetal testosterone in influencing brain development.

Males obviously produce far more prenatal testosterone than females do, but levels vary considerably even across members of the same sex. In fact, it may not be your sex per se that determines what kind of brain you have, but your prenatal hormone levels. From there it's a short leap to the intriguing idea that a male can have a typically female brain (if his testosterone levels are low), while a female can have a typically male brain (if her testosterone levels are high). That notion fits with the evidence that girls born with congenital adrenal hyperplasia, who for genetic reasons produce too much testosterone, are more likely to exhibit "tomboy" behavior than girls with more ordinary hormone levels.

What does all this have to do with autism? According to what I have called the "extreme male brain" theory of autism, people with autism simply match an extreme of the male profile, with a particularly intense drive to systemize and an unusually low drive to empathize. When adults with Asperger's syndrome (a subgroup on the autistic spectrum) took the same questionnaires we gave to non-autistic adults, they exhibited extreme Type S brains. Psychological tests reveal a similar pattern.

And this analysis makes sense. It helps explain the social disability in autism, because empathy difficulties make it harder to make and maintain relationships with others. It also explains the "islets of ability" that people with autism display in subjects like math or music or drawing - all skills that benefit from systemizing.

People with autism often develop obsessions, which may be nothing other than very intense systemizing at work. The child might become obsessed with electrical switches (an electrical system), or train timetables (a temporal system), or spinning objects (a physical system), or the names of deep-sea fish (a natural, taxonomic system). The child with severe autism, who may have additional learning difficulties and little language ability, might express his obsessions by bouncing constantly on a trampoline or spinning around and around, because motion is highly lawful and predictable. Some children with severe autism line objects up for hours on end. What used to be dismissed by clinicians as "purposeless, repetitive behavior" may actually be a sign of a mind that is highly tuned to systemize.

One needs to be extremely careful in advancing a cause for autism, because this field is rife with theories that have collapsed under empirical scrutiny. Nonetheless, my hypothesis is that autism is the genetic result of "assortative mating" between parents who are both strong systemizers. Assortative mating is the term we use when like is attracted to like, and there are four significant reasons to believe it is happening here.

FIRST, both mothers and fathers of children with autism complete the embedded figures test faster than men and women in the general population.

Second, both mothers and fathers of children with autism are more likely to have fathers who are talented systemizers (engineers, for example).

Third, when we look at brain activity with magnetic resonance imaging, males and females on average show different patterns while performing empathizing or systemizing tasks. But both mothers and fathers of children with autism show strong male patterns of brain activity.

Fourth, both mothers and fathers of children with autism score above average on a questionnaire that measures how many autistic traits an individual has. These results suggest a genetic cause of autism, with both parents contributing genes that ultimately relate to a similar kind of mind: one with an affinity for thinking systematically.

In order to fully test this theory, we still need to do a lot of work. The specific genes involved must be identified. It is a theory that may be controversial and perhaps unpopular among those who believe that the cause of autism is largely or totally environmental. But controversy is not a reason not to test it - systematically, as we might say.

Simon Baron-Cohen is the director of the autism research center at Cambridge University and the author of "The Essential Difference: The Truth About the Male and Female Brain."

Why No Tea and Sympathy?

By MAUREEN DOWD
WASHINGTON

W. can't get no satisfaction on Iraq.

There's an angry mother of a dead soldier camping outside his Crawford ranch, demanding to see a president who prefers his sympathy to be carefully choreographed.

A new CNN-USA Today-Gallup poll shows that a majority of Americans now think that going to war was a mistake and that the war has made the U.S. more vulnerable to terrorism. So fighting them there means it's more likely we'll have to fight them here?

Donald Rumsfeld acknowledged yesterday that sophisticated bombs were streaming over the border from Iran to Iraq.

And the Rolling Stones have taken a rare break from sex odes to record an antiwar song called "Sweet Neo Con," chiding Condi Rice and Mr. Bush. "You call yourself a Christian; I call you a hypocrite," Mick Jagger sings.

The N.F.L. put out a press release on Monday announcing that it's teaming up with the Stones and ABC to promote "Monday Night Football." The flag-waving N.F.L. could still back out if there's pressure, but the mood seems to have shifted since Madonna chickened out of showing an antiwar music video in 2003. The White House used to be able to tamp down criticism by saying it hurt our troops, but more people are asking the White House to explain how it plans to stop our troops from getting hurt.

Cindy Sheehan, a 48-year-old Californian with a knack for P.R., says she will camp out in the dusty heat near the ranch until she gets to tell Mr. Bush face to face that he must pull all U.S. troops out of Iraq. Her son, Casey, a 24-year-old Army specialist, was killed in a Sadr City ambush last year.

The president met with her family two months after Casey's death. Capturing W.'s awkwardness in traversing the line between somber and joking, and his love of generic labels, Ms. Sheehan said that W. had referred to her as "Mom" throughout the meeting, and given her the sense that he did not know who her son was.

The Bush team tried to discredit "Mom" by pointing reporters to an old article in which she sounded kinder to W. If only her husband were an undercover C.I.A. operative, the Bushies could out him. But even if they send out a squad of Swift Boat Moms for Truth, there will be a countering Falluja Moms for Truth.

It's amazing that the White House does not have the elementary shrewdness to have Mr. Bush simply walk down the driveway and hear the woman out, or invite her in for a cup of tea. But W., who has spent nearly 20 percent of his presidency at his ranch, is burrowed into his five-week vacation and two-hour daily workouts. He may be in great shape, but Iraq sure isn't.

It's hard to think of another president who lived in such meta-insulation. His rigidly controlled environment allows no chance encounters with anyone who disagrees. He never has to defend himself to anyone, and that is cognitively injurious. He's a populist who never meets people - an ordinary guy who clears brush, and brush is the only thing he talks to. Mr. Bush hails Texas as a place where he can return to his roots. But is he mixing it up there with anyone besides Vulcans, Pioneers and Rangers?

W.'s idea of consolation was to dispatch Stephen Hadley, the national security adviser, to talk to Ms. Sheehan, underscoring the inhumane humanitarianism of his foreign policy. Mr. Hadley is just a suit, one of the hard-line Unsweet Neo Cons who helped hype America into this war.

It's getting harder for the president to hide from the human consequences of his actions and to control human sentiment about the war by pulling a curtain over the 1,835 troops killed in Iraq; the more than 13,000 wounded, many shorn of limbs; and the number of slain Iraqi civilians - perhaps 25,000, or perhaps double or triple that. More people with impeccable credentials are coming forward to serve as a countervailing moral authority to challenge Mr. Bush.

Paul Hackett, a Marine major who served in Iraq and criticized the president on his conduct of the war, narrowly lost last week when he ran for Congress as a Democrat in a Republican stronghold in Cincinnati. Newt Gingrich warned that the race should "serve as a wake-up call to Republicans" about 2006.

Selectively humane, Mr. Bush justified his Iraq war by stressing the 9/11 losses. He emphasized the humanity of the Iraqis who desire freedom when his W.M.D. rationale vaporized.

But his humanitarianism will remain inhumane as long as he fails to understand that the moral authority of parents who bury children killed in Iraq is absolute.
