Sexual statistics

Cover

The plus team in Plus Magazine:

Straight men have had twice as many sexual partners, on average, as straight women. Sounds plausible, seeing that men supposedly think about sex every seven seconds. Except that it's mathematically impossible: in a closed population with as many men as women (which roughly there are) the averages should match up. Someone is being dishonest, but who? And why? These questions, along with many others, are explored in Sex by numbers, a new book by David Spiegelhalter, Winton Professor for the Public Understanding of Risk at the University of Cambridge.

“Sex is a great topic,” says Spiegelhalter. “There's lots of it going on, but we don't know what goes on or how much of it, because most of the time it goes on behind closed doors. It's a really difficult topic to investigate scientifically, and a real challenge for statistics.” Spiegelhalter's aim is to get people interested in a critical approach to the numbers they hear about in the news and give them the tools to figure out if they can be believed. “It's really a book about statistics, using sex as an example.”

Statistics about sex are not all equally good. Some, like the number of births in a given year, are cast-iron facts, but others are much harder to come by. The number of sexual partners is a good example. The mismatch above comes from the third The National Survey of Sexual Attitudes and Lifestyles (Natsal), conducted between 2010 and 2012, in which men reported having had 14 sexual partners, on average, and women 7. Studies have suggested that women give lower numbers when they fear the survey isn't entirely confidential, something that doesn't seem to affect men (contrary to my expectation, it doesn't induce them to exaggerate). So that's one possible explanation for the mismatch: sadly, women still need to fear social stigma.

But there are other explanations too. One is that men (more than women) may have some of their sexual experience with sex workers. These aren't included in the surveys, so their experiences are missing from the female tally. Another is that there are different attitudes as to what counts as a sexual partner. If a woman feels she's been coerced by a man, for example, she may not want to count him.

Black America’s Lost Generation Speaks Up

Kai Wright in The Nation:

ScreenHunter_1191 May. 10 18.50Allen Bullock became an unwitting star of the Baltimore riots. In a photo splashed across the front page of The Baltimore Sun, the 18-year-old stood on the hood of a cop car, smashing the windshield with an orange cone. It was a striking portrait of the youthful rage that has forced everyone from President Obama to Geraldo Rivera to belatedly notice West Baltimore’s pain.

Bullock’s well-meaning parents urged him to turn himself in to the police. “We wanted Allen to do the right thing,” his mother told The Guardian. That sentiment plunged the family into a trick bag of morality that black people routinely encounter when they brush up against the criminal-justice system. For smashing that window, Bullock is being held on $500,000 bail and faces a sentence of four to eight years in prison. Bail for the six officers charged with taking Freddie Gray’s life topped out at $350,000. We couldn’t ask for a starker example of property being valued higher than black life.

Whether Bullock and his peers had already done “the right thing” by erupting in the streets of Baltimore will remain the subject of debate for some time. What’s clear, though, is that their rioting prompted a remarkable shift in the public discussion over police violence. What had been a narrow debate about cops opened up into something larger—and more honest.

Is there a war instinct in humans?

David P Barash in Aeon:

ScreenHunter_1190 May. 10 18.46There is something peculiarly — even paradoxically — appealing about taking a dim view of human nature, a view that has become unquestioned dogma among many evolutionary biologists. It is a tendency that began some time ago. When the Australian-born anthropologist Raymond Dart discovered the first australopithecine fossil in 1924, he went on to describe these early hominids as:
Confirmed killers: carnivorous creatures that seized living quarries by violence, battered them to death, tore apart their broken bodies, dismembered them limb from limb, slaking their ravenous thirst with the hot blood of the victims and greedily devouring living writhing flesh.

This lurid perspective has deep antecedents, notably in certain branches of Christian doctrine. According to the zealous 16th century French theologian John Calvin:
The mind of man has been so completely estranged from God’s righteousness that it conceives, desires, and undertakes, only that which is impious, perverted, foul, impure and infamous. The human heart is so steeped in the poison of sin, that it can breathe out nothing but a loathsome stench.

It’s bad enough for the religious believer to be convinced of humanity’s irrevocable sinfulness, punishable in the afterlife. But I’m even more concerned when those who speak for science and reason promote a theory of human nature that threatens to become a self-fulfilling prophecy.

Sunday Poem

My Father-in-law at Twenty

when mother-in-law is in China
father-in-law will take off his shirt
unwire the ancestral wok from the ancestral nail
mix salt and steam and cigarette ash into the fried rice
he learned to make in London.

in London when he was twenty
standing by a snowy statue in Trafalgar Square
someone taking black and white woman
in an expensive white hat.

he handsome in a dark suit
speaking dishwater English yet
the way he held his cigarette
the way he leaned towards her
dismissed the camera the cold
the woman must have understood.

I have seen those pictures
my wife knows where they are hid
and he once told me when others were in bed
how on the ship from Hong Kong to London
there was more than one fistfight with gweilo
except when the ship stopped in Egypt
a ceasefire to see the Sphinx

he has lost the photos, he says,
smiling,
coughing,
checking his heart,
blowing smoke away from me,
too long ago.

for my father-in-law at twenty
the sands of Egypt spicy under his feet
fists bloodied against condensation
stacks of unwashed dishes awaiting his arrival in London
and a mysterious white woman
smiling at him from under an expensive white hat
the riddles of the Sphinx must once have seemed
no more difficult than striking a match on ice.

Mom: The Designated Worrier

Judith Shulevitz in The New York Times:

As I was thinking about Mother's Day today and read the article below in the NYT, I remembered the following which validates the thesis presented: I once asked my mother that she had raised seven children, did she have a favorite? She promptly said, yes, of course. I was so shocked at this blatant admission and the first thought I had was I will kill myself if it is not me. Who, I demanded nervously. She wisely responded, 'Anyone of you who is vulnerable at the moment becomes my favorite and all my love and attention becomes focused on that child. So all of you have taken turns to be my favorite'.

MothersTHERE’S a story my daughter loves to hear me tell: The day after I came home from the hospital with her big brother, my first child, I was seized by the certainty that I was about to die. I sobbed; I asked my husband: “But who will keep him in socks? Who’ll make sure he’s wearing his little socks?” “Didn’t you think Daddy could put the socks on?” my daughter exclaims, delighted that I’d been so ridiculous. “I wasn’t sure he’d remember,” I say, “or have enough on hand.” New parenthood, of course, does things to your brain. But I was on to something, in my deranged, postpartum way. I should state for the record that my husband is perfectly handy with socks. Still, the parent more obsessed with the children’s hosiery is the one who’ll make sure it’s in stock. And the shouldering of that one task can cascade into responsibility for the whole assembly line of childhood. She who buys the bootees will surely buy the bottle washer, just as she’ll probably find the babysitter and pencil in the class trips. I don’t mean to say that she’ll be the one to do everything, just that she’ll make sure that most everything gets done. Sociologists sometimes call the management of familial duties “worry work,” and the person who does it the “designated worrier,” because you need large reserves of emotional energy to stay on top of it all.

I wish I could say that fathers and mothers worry in equal measure. But they don’t. Disregard what your two-career couple friends say about going 50-50. Sociological studies of heterosexual couples from all strata of society confirm that, by and large, mothers draft the to-do lists while fathers pick and choose among the items. And whether a woman loves or hates worry work, it can scatter her focus on what she does for pay and knock her partway or clean off a career path. This distracting grind of apprehension and organization may be one of the least movable obstacles to women’s equality in the workplace. IT’S surprising that household supervision resists gender reassignment to the degree that it does. In the United States today, more than half of all women work, and women are 40 percent of the sole or primary breadwinners in households with children under 18. The apportionment of the acts required to keep home and family together has also been evening out during the past 40 years (though, for housework, this is more because women have sloughed it off than because men have taken it on). Nonetheless, “one of the last things to go is women keeping track of the kind of nonroutine details of taking care of children — when they have to go to the doctor, when they need a permission slip for school, paying attention at that level,” says the social psychologist Francine Deutsch, author of “Halving It All: How Equally Shared Parenting Works.”

‘The Wright Brothers,’ by David McCullough

Daniel Okrent in the New York Times:

10OKRENT2-blog427It’s been nearly half a century since David McCullough published “The Johns­town Flood,” which initiated his career as our matchless master of popular history. His 10th book, “The Wright Brothers,” has neither the heft of his earlier volumes nor, in its intense focus on a short period in its subjects’ lives, the grandness of vision that made those works as ambitious as they were compelling. Yet this is nonetheless unmistakably McCullough: a story of timeless importance, told with uncommon empathy and fluency.

It does not begin promisingly. The first 30 or so pages consist of a somewhat desultory recounting of early years in the Wright household. But then 32-year-old Wilbur writes a letter to the Smithsonian, requesting any papers they have, or know of, regarding human flight. “I am an enthusiast,” he assures whoever might open the letter, “but not a crank in the sense that I have some pet theories as to the proper construction of a flying machine.”

Did he ever. There is no fortuity in the Wright brothers’ saga as related by McCullough, no unexpected events that changed their course. Except for Orville’s startling emergence from a horrible wreck during one of his flights, there’s not even any luck. Neither brother attended college, nor had been trained in physics or engineering, yet each step they took was not only correct but in many cases brilliant, and in nearly all cases original. That every one of those steps was also achieved through excruciating patience and obsessive attention to detail does not diminish the only word that can express what Wilbur, particularly, possessed: genius.

McCullough shows how endless calculation, application and recalculation led them to determine the proper shape of the wing, the means of manipulating its angle into the wind, how to compensate for the weight of the engine.

Analog Simulators Could Be Shortcut to Universal Quantum Computers

Peter Byrne in Scientific American:

ScreenHunter_1188 May. 09 17.13For more than 20 years, Ivan Deutsch has struggled to design the guts of a working quantum computer. He has not been alone. The quest to harness the computational might of quantum weirdness continues to occupy thousands of researchers around the world. Why hasn’t there been more to show for their work? As physicists have known since quantum computing’s beginnings, the same characteristics that make quantum computing exponentially powerful also make it devilishly difficult to control. The quantum computing “nightmare” has always been that a quantum computer’s advantages in speed would be wiped out by the machine’s complexity.

Yet progress is arriving on two main fronts. First, researchers are developing unique quantum error-correction techniques that will help keep quantum processors up and running for the time needed to complete a calculation. Second, physicists are working with so-called analog quantum simulators—machines that can’t act like a general-purpose computer, but rather are designed to explore specific problems in quantum physics. A classical computer would have to run for thousands of years to compute the quantum equations of motion for just 100 atoms. A quantum simulator could do it in less than a second.

Quanta magazine spoke with Deutsch about recent progress in the field, his hopes for the near future, and his own work on scaling up binary quantum bits into base-16 digits.

QUANTA MAGAZINE: Why would a universal quantum machine be so uniquely powerful?

IVAN DEUTSCH: In a classical computer, information is stored in retrievable bits binary coded as 0 or 1. But in a quantum computer, elementary particles inhabit a probabilistic limbo called superposition where a “qubit” can be coded as 0 and 1.

Here is the magic: Each qubit can be entangled with the other qubits in the machine. The intertwining of quantum “states” exponentially increases the number of 0s and 1s that can be simultaneously processed by an array of qubits. Machines that can harness the power of quantum logic can deal with exponentially greater levels of complexity than the most powerful classical computer. Problems that would take a state-of-the-art classical computer the age of our universe to solve, can, in theory, be solved by a universal quantum computer in hours.

Chicago, Babylon

Zaheer Kazmi in The Brooklyn Rail:

Kazmi-web1The Sears Tower in Chicago, renamed the Willis Tower in 2009, was once renowned for being the tallest skyscraper in the world, outstripping even the World Trade Center’s Twin Towers in its bid to reach the heavens. It too stands fantastically high—an awesome testament to human ingenuity, American power, and hubris.

In his musical homage to Illinois, the American songwriter, Sufjan Stevens, weaves together a collection of allusive, often dark and beautiful vignettes about the Prairie State subtly suffused with a spirit of Biblical mysticism. In the haunting song, “The Seer’s Tower,” evoking images of the Tower of Babel, Stevens intones ominously about the “tower above the earth […] built for Emmanuel.”

Seven miles above the earth,
There is Emmanuel of mothers.
With his sword, with his robe,
He comes dividing man from brothers.

Like God’s fateful decision to alienate the living from one another at Babel by creating intractable differences between them, the earthly arrival of the son of God, foretold in the prophecy of Emmanuel, also presaged division and conflict in the city of man. Once God is among us, a sacred unity is broken. Between the believers and the damned, the harbingers of divine truth leave only violence in their wake.

The play on the words, “Seer/Sear,” in the title of Stevens’s song conjures up prophetic visions and the violence they portend as much as the God’s eye view of the city from the top of the Chicago landmark.

‘Hold Still,’ a Memoir by Sally Mann

10PROSE-master675-v2Francine Prose at The New York Times:

Before reading “Hold Still,” my knowledge of Sally Mann was based entirely on her photographs of her family on their Virginia farm, her dreamlike Southern landscapes, and some memory of the controversies that have surrounded the question of whether her intimate portraits of her children, often nude, were exploitative. I’d assumed she was continuing to make new work and enjoying placid rural domesticity periodically interrupted by brief but abrasive trials in the court of public opinion.

Now her wonderfully weird and vivid memoir — generously illustrated with family snapshots, her own and other people’s photos, documents and letters — describes a life more dramatic than I had imagined. Perhaps that should be unsurprising, given how deeply her psyche and her oeuvre seem to have been marked by the South, its live oaks dripping Spanish moss, its terrible record on race and its multigenerational dynasties hiding gothic Faulknerian secrets.

Werner Herzog’s walking blues

David L. Ulin at the LA Times:

“Why is walking so full of woe?” Werner Herzog asks early in “Of Walking in Ice: Munich-Paris, 23 November – 14 December 1974” (University of Minnesota Press: 128 pp., $19.95 paper), a diary of sorts describing a 600-mile trek through winter that he undertook 40 years ago.

If this sounds quintessentially Herzog, quintessentially quixotic, so be it; in his films — most notably, perhaps, the hallucinatory “Fitzcarraldo” and “Aguirre, the Wrath of God” — he traces the price, and power, of obsession to both ennoble and dismantle us. Something similar is at work in this slender book, originally published in 1978 and newly restored to print.

The inspiration for the project is a phone call Herzog received in late 1974, informing him that a friend, the German film historian Lotte Eisner, was close to death in a Paris hospital. As an act of expiation, then, or maybe magic, Herzog decided to walk from Munich to Eisner’s bedside, as if, through such his relentless movement, he might keep her alive.

Biologists and philosophers debate altruism

A408039b-682b-4a04-a173-89397cb4cac4Stephen Cave at the Financial Times:

In Does Altruism Exist? Culture, Genes, and the Welfare of Others, David Sloan Wilson sets out the evolutionary story. How we might have evolved to be self-sacrificing has long been a challenge for Darwinism — after all, those who give their lives to save their community do not pass on their genes. Even less extreme kindnesses such as sharing food with a sick friend could put someone at a disadvantage in the ruthless race to be the fittest.

Various theories have been put forward to solve this puzzle. Wilson, professor of biology and anthropology at the Binghamton University in New York State, has long been an advocate of one in particular called group selection. He claims that this view has now won out; a claim with which many biologists would disagree. But in this short and punchy book, he does an excellent job of explaining the relationship between the different theories and the now substantial evidence that we have indeed evolved to do each other good turns.

The essence of group selection is this: “although a high standard of morality gives but a slight or no advantage to each individual man and his children over other men of the same tribe . . . an increase in the number of well-endowed men and an advancement in the standard of morality will certainly give an immense advantage to one tribe over another. A tribe including many members who, from possessing a high degree of the spirit of patriotism, fidelity, obedience, courage, and sympathy were always ready to aid one another, and to sacrifice themselves for the common good, would be victorious over most other tribes, and this would be natural selection.”

An Interview with the Publisher of a Magazine Printed Using HIV-Positive Blood

Markus Lust in Vice:

Vangardist-julian-wiehl-hiv-blood-ink-interview-876-body-image-1431095286An Austrian gay mag called Vangardist made headlines around the world this week for using the blood of three HIV-positive people to print its new issue. The sterilized blood carrying the virus was used on 3,000 of 18,000 copies, and was intended to address the stigmatization many people living with HIV deal with on a daily basis. The issue is of course completely safe to handle, and researchers from Harvard and Austria's Innsbruck University provided guidance to the magazine throughout the process. The issue deals with the history behind the stigmatization of HIV patients, the state of the disease today, and contains interviews with each of the donors. Proceeds from the issue's sales will be donated to HIV and AIDS charities. I got in touch with Vangardist's publisher, Julian Wiehl, to talk about the campaign, Conchita Wurst, and his HIV Heroes initiative.

VICE: What did you hope to achieve with the current issue of Vangardist? Julian Wiehl: We wanted to raise awareness for HIV—but also point out that people who carry the virus are still extremely stigmatized in our society. The problem is not that HIV never hit the headlines. The problem is that HIV doesn't make headlines any longer. Everybody seems to think we've heard enough about it. But the reaction to our print magazine shows that there's obviously still lots of work to do. Unfortunately, reporting on the topic in a matter-of-fact way is not enough

Life is two things— what you get
and what you do with what you get
…………………. —Roshi Bob

Foxtrot

In five days Raul will die from falling
On a knife blade held in the fist of
An acquaintance.
His good friend Paulo will hold him
In his arms and cradle his
Shaved head,
While Raul's eyes express surprise
At the possibility—no, it is
The impending reality—yes, that life
Is quickly leaving his body.
And Raul's mind must race
To keep up with his soul's
Unscheduled departure.

But that will be five days hence. Right now,
Raul and Paulo and the rest of their crew
Are slogging through the crowded mall,
Adjusting loose waistbands, step step;
Shifting Sox headgear, three four;
Dragging trains of Nike laces
Among the threads of frayed pant legs,
As passers-by shift and pivot around them
One, two, onetwothree.

When Mother Leaves the Room

Anne Enright in The New York Times:

MomEvery year on Mother’s Day the lists appear: Bad Mothers in Fiction, Monstrous Mothers in Literature, 10 Worst Mothers in Books We Love. There are a few Most Wonderful lists, but these mothers are not from books generally recognized as great or enduring works. The two most famous are Caroline Ingalls in “Little House on the Prairie” and Marmee in “Little Women” — it’s a bonnet thing perhaps, though a good straw poke does not save Mrs. Bennet in “Pride and Prejudice” from the charge of foolishness. This makes you a bad mother too, apparently. Perhaps there should be an exam. Who could pass it? To be ordinary in any way — weak, fallible, occasionally drunk or desiring, all of these make you a liability to your fictional children’s fictional well- being. Thank goodness reality is not like that.

It’s a given that adulterous women make poor mothers; this is both sin and punishment for Emma Bovary and Anna Karenina, who lose not just their children, but their proper maternal instinct. First, and perhaps forgivably, they fall out of love with their husbands, but this leads them, somehow, to fall out of love with their own progeny. The perversion of the natural order becomes horribly perfect in Waugh’s “A Handful of Dust,” when Brenda Last blurts “Thank God” when she hears her son has died, and not, as she had supposed, her lover of the same name. When desire is in the air, motherhood becomes problematic. This despite the fact that sex causes motherhood. It is a fact worth stating sometimes that sex, in itself, cannot turn you into a whore, no matter what the nuns told you then or pornography tells you now, but it really can turn you into a mother. After which, of course, you are never allowed to have sex again.

Engineering students build a better barbecue smoker

Alvin Powell in the Harvard Gazette:

ScreenHunter_1187 May. 08 23.44Professor Kevin “Kit” Parker set 16 students in his “Engineering Sciences 96” class to a real-world test of teamwork, technical skill, and dedication this semester, assigning them the 14-week task of building a better barbecue smoker.

Along the way, they had to decode the arcane process of smoking meat, applying science to a traditional Southern art form with the aim of simplifying it for the novice and updating it for the 21st century. They had a real-world client in Williams-Sonoma, the company that sponsored their efforts; real-world competition in their experimental control, a high-end smoker called the “Big Green Egg”; and the real world itself to contend with, in the form of snowstorms and subzero temperatures for their Saturday smoking sessions.

“I was eating it last night as it came off the smoker, and it was fantastic,” said Patrick Connolly, Williams-Sonoma executive vice president and chief marketing officer, who was at an end-of-semester barbecue Monday where the culinary results were presented.

Connolly was among several dozen guests, students, faculty, and staff at the barbecue, held just outside Harvard’s Maxwell-Dworkin building. The barbecue followed an hour-long student presentation of the scientific results of the project in nearby Pierce Hall.

The Road to Jerusalem

IC_MEIS_ISRAEL_FI_003

Morgan Meis in The Smart Set:

The highway from Tel Aviv to Jerusalem, Highway 1, looks like any other highway in the world. This fact alone is disconcerting. The road to Jerusalem should be special. Somewhere deep down I suppose I wanted it to be a dirt road, a cobblestone road, anything but a normal highway. I even fantasized that the ascent from Tel Aviv to Jerusalem would not happen by means of a road at all. It would just happen. In reality, it is a highway. A highway filled with too many cars and bastard truck drivers probing the limits of vehicular stability and good sense.

About two thirds of the way up to Jerusalem, however, an interesting and unusual sight does present itself. It is the sight of abandoned vehicles along the side of the road. They aren’t normal vehicles, passenger cars or trucks. The vehicles are painted in the telltale green that only gets slapped on things owned by the military. You don’t get much time to inspect these military vehicles as you drive by on the highway. It is hard to guess their purpose, though it looks like they’ve been there for a while, remnants from something that happened in the first half of the 20th century.

My friend Ori, who was driving me from Ben-Gurion airport outside of Tel Aviv, explained that the vehicles were remnants of the military convoy that broke the Arab siege of Jerusalem during the War of Independence in 1948. The convoy was led by an American general, Mickey Marcus, Ori told me. “We call him the first Israeli general—aluf in Hebrew—since biblical days, since Joshua blowing his trumpet at the walls of Jericho.” The aluf, Ori said, was shot dead in the final days of the campaign. But the convoy made it through to Jerusalem.

For a week or so, while exploring Jerusalem old and new, the sight of those abandoned military vehicles along the road sat unbothered in the back of my brain. Then, I saw them again on a trip back down to Tel Aviv to visit friends. I began to understand what had nagged at me when I saw the vehicles the first time.

Half-destroyed military vehicles do not normally sit alongside a modern highway. These vehicles are monuments to the military struggles that attend the founding of the modern state of Israel. Such monuments might, in another country, come with an acknowledgment. No such luck in Israel.
