DSK and Conspiracy Theory

by Roger Cohen

New York Times

May 30, 2011

After Osama bin Laden was killed, a prominent French radio station called me for an interview. It turned into a mildly hallucinogenic experience. Everybody from the president of the United States to Al Qaeda itself was saying Bin Laden was dead, but my interviewer kept pressing me for “the proof.”

I talked about DNA samples, the word of the American president, the accumulated intelligence, but it was clear that a Gallic conspiracy reflex — especially active with regard to France’s sometime American savior — had kicked in. The view that this might all be some U.S. plot or hoax had taken mysterious hold.

I was put in mind of an unpleasant Paris dinner when a France Télécom manager with international experience began to expound on the theory — more than plausible to his mind — that Jews had not turned up to work at the twin towers on 9/11 because Israel and the Mossad were behind the planes-turned-missiles that turned lower Manhattan into an inferno.

And now we have the Dominique Strauss-Kahn sexual assault case, viewed, it seems, by close to 60 percent of French society as a conspiracy against the putative Socialist presidential candidate — a sting operation that somehow placed a West African immigrant maid in a $3,000 a night Sofitel suite whose number, 2806, corresponds to the date of the opening of the Socialist party primaries in France (06-28).

Oh, s’il vous please!

A rough rule goes like this: The freer a society the less inclined it is to conspiracy theories, while the greater its culture of dependency the more it will tend to see hidden hands at work everywhere.

Dan Dennett: Cute, sexy, sweet, funny

TED
February 2009

Why are babies cute? Why is cake sweet? Philosopher Dan Dennett has answers you wouldn't expect, as he shares evolution's counterintuitive reasoning on cute, sweet and sexy things (plus a new theory from Matthew Hurley on why jokes are funny).

Philosopher and scientist Dan Dennett argues that human consciousness and free will are the result of physical processes and are not what we traditionally think they are. His 2003 book Freedom Evolves explores the way our brains have evolved to give us -- and only us -- the kind of freedom that matters, while 2006's Breaking the Spell examines religious belief through the lens of biology.

The Optimism Bias

by Tali Sharot

Time

May 28, 2011

We like to think of ourselves as rational creatures. We watch our backs, weigh the odds, pack an umbrella. But both neuroscience and social science suggest that we are more optimistic than realistic. On average, we expect things to turn out better than they wind up being. People hugely underestimate their chances of getting divorced, losing their job or being diagnosed with cancer; expect their children to be extraordinarily gifted; envision themselves achieving more than their peers; and overestimate their likely life span (sometimes by 20 years or more).

The belief that the future will be much better than the past and present is known as the optimism bias. It abides in every race, region and socioeconomic bracket. Schoolchildren playing when-I-grow-up are rampant optimists, but so are grownups: a 2005 study found that adults over 60 are just as likely to see the glass half full as young adults.

You might expect optimism to erode under the tide of news about violent conflicts, high unemployment, tornadoes and floods and all the threats and failures that shape human life. Collectively we can grow pessimistic — about the direction of our country or the ability of our leaders to improve education and reduce crime. But private optimism, about our personal future, remains incredibly resilient. A survey conducted in 2007 found that while 70% thought families in general were less successful than in their parents' day, 76% of respondents were optimistic about the future of their own family.

Sex, Lies, Arrogance: What Makes Powerful Men Act Like Pigs*

Time
May 19, 2011

When her husband Dominique Strauss-Kahn was preparing to run for President of France five years ago, Anne Sinclair told a Paris newspaper that she was "rather proud" of his reputation as a ladies' man, a chaud lapin (hot rabbit) nicknamed the Great Seducer.

"It's important," she said, "for a man in politics to be able to seduce."

Maybe it was pride that inspired French politicians and International Monetary Fund officials to look the other way as the rumors about "DSK" piled up, from the young journalist who says Strauss-Kahn tried to rip off her clothes when she went to interview him, to the female lawmaker who describes being groped and pawed and vowed never to be in a room alone with him again, to the economist who argued in a letter to IMF investigators that "I fear that this man has a problem that, perhaps, made him unfit to lead an institution where women work under his command." Maybe it was the moral laziness and social coziness that impel elites to protect their own. Maybe it was a belief that he alone could save the global economy. Maybe nothing short of jail is disqualifying for certain men in certain circles.

But in any event, the arrest of Strauss-Kahn in New York City for allegedly trying to rape a hotel maid has ignited a fierce debate over sex, law, power and privilege. And it is only just beginning. The night of Strauss-Kahn's arraignment, former California governor Arnold Schwarzenegger admitted that the reason his wife Maria Shriver walked out earlier this year was the discovery that he had fathered a child more than a decade ago with a former member of the household staff. The two cases are far apart: only one man was hauled off to jail. But both suggest an abuse of power and a betrayal of trust. And both involve men whose long-standing reputations for behaving badly toward women did not derail their rise to power. Which raises the question: How can it be, in this ostensibly enlightened age, when men and women live and work as peers and are schooled regularly in what conduct is acceptable and what is actionable, that anyone with so little judgment, so little honor, could rise to such heights?

Make My Bed? But You Say the World’s Ending

New York Times
May 19, 2011

The Haddad children of Middletown, Md., have a lot on their minds: school projects, SATs, weekend parties. And parents who believe the earth will begin to self-destruct on Saturday.

The three teenagers have been struggling to make sense of their shifting world, which started changing nearly two years ago when their mother, Abby Haddad Carson, left her job as a nurse to “sound the trumpet” on mission trips with her husband, Robert, handing out tracts. They stopped working on their house and saving for college.

Last weekend, the family traveled to New York, the parents dragging their reluctant children through a Manhattan street fair in a final effort to spread the word.

“My mom has told me directly that I’m not going to get into heaven,” Grace Haddad, 16, said. “At first it was really upsetting, but it’s what she honestly believes.”

Thousands of people around the country have spent the last few days taking to the streets and saying final goodbyes before Saturday, Judgment Day, when they expect to be absorbed into heaven in a process known as the rapture. Nonbelievers, they hold, will be left behind to perish along with the world over the next five months.

A New Gauge to See What’s Beyond Happiness

by John Tierney

New York Times

May 16, 2011

Is happiness overrated?

Martin Seligman now thinks so, which may seem like an odd position for the founder of the positive psychology movement. As president of the American Pyschological Association in the late 1990s, he criticized his colleagues for focusing relentlessly on mental illness and other problems. He prodded them to study life’s joys, and wrote a best seller in 2002 titled Authentic Happiness.

But now he regrets that title. As the investigation of happiness proceeded, Dr. Seligman began seeing certain limitations of the concept. Why did couples go on having children even though the data clearly showed that parents are less happy than childless couples? Why did billionaires desperately seek more money even when there was nothing they wanted to do with it?

And why did some people keep joylessly playing bridge? Dr. Seligman, an avid player himself, kept noticing them at tournaments. They never smiled, not even when they won. They didn’t play to make money or make friends.

They didn’t savor that feeling of total engagement in a task that psychologists call flow. They didn’t take aesthetic satisfaction in playing a hand cleverly and “winning pretty.” They were quite willing to win ugly, sometimes even when that meant cheating.

“They wanted to win for its own sake, even if it brought no positive emotion,” says Dr. Seligman, a professor of psychology at the University of Pennsylvania. “They were like hedge fund managers who just want to accumulate money and toys for their own sake. Watching them play, seeing them cheat, it kept hitting me that accomplishment is a human desiderata in itself.”

This feeling of accomplishment contributes to what the ancient Greeks called eudaimonia, which roughly translates to “well-being” or “flourishing,” a concept that Dr. Seligman has borrowed for the title of his new book, Flourish. He has also created his own acronym, Perma, for what he defines as the five crucial elements of well-being, each pursued for its own sake: positive emotion, engagement (the feeling of being lost in a task), relationships, meaning and accomplishment.

“Well-being cannot exist just in your own head,” he writes. “Well-being is a combination of feeling good as well as actually having meaning, good relationships and accomplishment.”

Attractive People Mate More Often

"Physical attractiveness influences reproductive success of modern men"
by P. Prokop and Peter Fedor

Abstract

Theory suggests that reproductive success is positively associated with an individual’s genetic quality. However, the association between physical attractiveness and reproductive success (i.e., number of offspring) in modern humans remains less clear. Here we examined associations between men’s reproductive success and physical attractiveness from retrospective data obtained from married, divorced, and single samples of Slovakian men. As predicted, facially more attractive and taller men were more likely to engage in marriage. In turn, married men had higher reproductive success than single men. Even when men’s marital status was considered, facially more attractive men had higher reproductive success than their less attractive counterparts. This supports the importance of physical attractiveness in sexual selection in modern humans.

The Tricky Chemistry of Attraction

by Shirley S. Wang

Wall Street Journal

May 9, 2011

Much of the attraction between the sexes is chemistry. New studies suggest that when women use hormonal contraceptives, such as birth-control pills, it disrupts some of these chemical signals, affecting their attractiveness to men and women's own preferences for romantic partners.

The type of man a woman is drawn to is known to change during her monthly cycle—when a woman is fertile, for instance, she might look for a man with more masculine features. Taking the pill or another type of hormonal contraceptive upends this natural dynamic, making less-masculine men seem more attractive, according to a small but growing body of evidence. The findings have led researchers to wonder about the implications for partner choice, relationship quality and even the health of the children produced by these partnerships.

Evolutionary psychologists and biologists have long been interested in factors that lead to people's choice of mates. One influential study in the 1990s, dubbed the T-shirt study, asked women about their attraction to members of the opposite sex by smelling the men's T-shirts. The findings showed that humans, like many other animals, transmit and recognize information pertinent to sexual attraction through chemical odors known as pheromones.

The study also showed that women seemed to prefer the scents of men whose immune systems were most different from the women's own immune-system genes known as MHC. The family of genes permit a person's body to recognize which bacteria are foreign invaders and to provide protection from those bugs. Evolutionarily, scientists believe, children should be healthier if their parents' MHC genes vary, because the offspring will be protected from more pathogens.

Census Data Reveals a Shift in Patterns of Childbearing

New York Times
May 9, 2011

College-educated women are waiting longer to have children than those without a college education, according to new data from the Census Bureau.

In 2000, the portion of women with college degrees between the ages of 25 and 34 who had children was 42 percent, according to the data. Ten years later, the same group of women, now ages 35 to 44 — representing about three million Americans — were far more likely to be mothers: About 76 percent had children, according to the data.

In contrast, women who did not finish high school were more likely to have children earlier. In 2000, about 83 percent of women ages 25 to 34 who did not have a high school diploma had children. The percentage rose to 88 percent by 2010.

The trend of educated women having children later accelerated in the 1980s, along with the rise in women’s educational attainment, said Andrew J. Cherlin, a demographer at Johns Hopkins University.

“College-educated women are following a different path to having children,” Mr. Cherlin said. “They wait until they’ve graduated from college, gotten married and started a career, before having a child.”
