Years ago, I told Tyler Cowen, "It's surprising that IQ tests predict life outcomes so well, because there's usually no financial incentive to get a high score." He replied, "People try out of pride - an under-rated motive." So when Tyler blogged Duckworth et al, "Role of Test Motivation in Intelligence Testing" I naturally took notice. Key claims:
1. Material incentives boost IQ scores: ... "The authors reasonably infer that IQ is more of a composite intelligence/motivation measure than usually believed - especially by inter-disciplinary researchers."
As far as I can tell, the authors do nothing to show that their results make IQ is less predictive. They don't even show that IQ is more mutable than earlier studies find; boosting incentives boosts scores while the incentives remain in place, but there's no reason to think the boost lasts after the test-takers receive their pay. All the researchers require us to reconsider is the reason why IQ is so predictive and hard to durably improve.
Q. So, you're saying that IQ testing can tell us more about group differences than about individual differences?
A. If the sample sizes are big enough and all else is equal, a higher IQ group will virtually always outperform a lower IQ group on any behavioral metric....
Of course, everything else is seldom equal. A more conscientious group may well outperform a higher IQ group. On the other hand, conscientiousness, like many virtues, is positively correlated with IQ, so IQ tests work surprisingly well.
Q. Wait a minute, does that mean that maybe some of the predictive power of IQ comes not from intelligence itself, but from virtues associated with it like conscientiousness?
A. Most likely. But perhaps smarter people are more conscientious because they are more likely to foresee the bad consequences of slacking off. It's an interesting philosophical question, but, in a practical sense, so what? We have a test that can predict behavior. That's useful.
Student Named Yesenia: "Teacher! Teacher! I have a question."
Teacher: "Yes, what is it?"
Yesenia: "Who is Son of Aladdin? Why are they always looking for him in a cave?"
Teacher: "Huh?"
Yesenia: "What's so bad about Son of Aladdin? Why are they trying to catch him?"
Teacher: "Oh, you mean … Osama bin Laden?"
Yesenia: "Yeah, Son of Aladdin."
Teacher: "He's a terrorist."
Yesenia: "Oh."
Teacher [trying to make this into a Teachable Moment]: "But don't confuse Osama with Obama."
Yesenia: "Who's that?"
Teacher: "Barack Obama. He's running for President. The African-American candidate."
Yesenia:
Teacher: "You know, the black guy?"
Yesenia [Eyes widening]: "He's black?"
Teacher: "Yes."
Yesenia: "And he's running for President?"
Teacher: "Yes."
Yesenia: [With wide-eyed alarm]: "That's bad."
Asked about what else he was doing while on the East Coast, [Indiana governor Mitch Daniels] said he was going to Washington to accept an award from the Arab American Institute. “I happen to be one,” he said—an Arab American, that is. His paternal grandparents immigrated from Syria. Somehow I hadn’t registered that aspect of Daniels’s background before. I guess it makes Daniels even less likely to traffic in the kind of disgusting, racially-tinged, Muslim-baiting, xenophobic hate-mongering that some of his “brethren” (and sistren) have flirted with. ~Hendrik Hertzberg
Their Fates Were SEALed
Forget the U.S. version of the Bin Laden raid. Any adult male found in the compound was a dead man.
By William Saletan
U.S. officials provided new details on bin Laden’s final moments, saying the al-Qaeda leader was first spotted by U.S. forces in the doorway of his room on the compound’s third floor. Bin Laden then turned and retreated into the room before being shot twice — in the head and in the chest.
“He was retreating,” a move that was regarded as resistance, a U.S. official briefed on the operation said. “You don’t know why he’s retreating, what he’s doing when he goes back in there. Is he getting a weapon? Does he have a [suicide] vest?”
The Obama administration was investigating whether Pakistan knew Osama bin Laden was hiding deep inside the country as House Speaker John Boehner and top lawmakers insisted the U.S. maintain close ties with the sometimes reluctant ally in the war on terror. The killing of Osama bin Laden at a compound just miles from Islamabad prompted furious questions about whether Pakistan was complicit in protecting the mastermind of the Sept. 11 attacks...Amid the harsh criticism of Pakistan, Boehner and others said this was not the time to back away from Pakistan. "I think we need more engagement, not less," he said. "Al-Qaida and other extremist groups have made Pakistan a target. ... Having a robust partnership with Pakistan is critical to breaking the back of al-Qaida and the rest of them."
Israel has viewed Turkey as an ally since before it declared statehood. Turkey, along with Ethiopia and Iran (the latter of course being a much different story) made up Ben-Gurion’s Periphery Doctrine. Recognizing that in the short-term, Israel would not be able to work with its Arab neighbors, he looked to reach out to Israel’s “periphery” as a means of having allies in the region.
Cognitive Capitalism: The Effect of Cognitive Ability on Wealth, as Mediated Through Scientific Achievement and Economic Freedom
Heiner Rindermann and James Thompson
Chemnitz University of Technology and University College London
Abstract
Traditional economic theories stress the relevance of political, institutional, geographic, and historical factors for economic growth. In contrast, human-capital theories suggest that peoples’ competences, mediated by technological progress, are the deciding factor in a nation’s wealth. Using three large-scale assessments, we calculated cognitive-competence sums for the mean and for upper- and lower-level groups for 90 countries and compared the influence of each group’s intellectual ability on gross domestic product. In our cross-national analyses, we applied different statistical methods (path analyses, bootstrapping) and measures developed by different research groups to various country samples and historical periods. Our results underscore the decisive relevance of cognitive ability—particularly of an intellectual class with high cognitive ability and accomplishments in science, technology, engineering, and math—for national wealth. Furthermore, this group’s cognitive ability predicts the quality of economic and political institutions, which further determines the economic affluence of the nation. Cognitive resources enable the evolution of capitalism and the rise of wealth.
First off, Andy Hiller, political reporter for WHDH-TV in Boston, Massachusetts, wanted to know whether the potential next president of the US could name the president of Chechnya.
Mr Bush: "No, can you?"
Instead, Mr Hiller fired off his second question. "Can you name the president of Taiwan?"
Bush: "Yeah, Lee." His score so far: 50%.
But then came the crunch question: "Can you name the general who is in charge of Pakistan?"
Mr Bush needed a breather. "Wait, wait, is this 50 questions?"
"No, it's four questions of four leaders in four hot spots, " the reporter tried to put his victim at ease.
"The new Pakistani general, he's just been elected - not elected, this guy took over office. It appears this guy is going to bring stability to the country and I think that's good news for the sub-continent," the Republican candidate offered.
Good news, but not an answer, and the interviewer insisted: "Can you name him?"
"General. I can't name the general. General" was all Mr Bush had to offer.
The reporter tried the another country in the same region, but the Indian prime minister's name did not come to George Bush either.
"The new prime minister of India is - no."
Barack Obama came to Washington just six years ago, having spent his professional life as a part-time lawyer, part-time law professor, and part-time state legislator in Illinois. As an undergraduate, he took courses in history and international relations, but neither his academic life nor his work in Springfield gave him an especially profound grasp of foreign affairs. ...
As a student during the Reagan years, Obama gravitated toward conventionally left-leaning positions. At Occidental, he demonstrated in favor of divesting from apartheid South Africa. At Columbia, he wrote a forgettable essay in Sundial, a campus publication, in favor of the nuclear-freeze movement. As a professor at the University of Chicago, he focussed on civil-rights law and race. And, as a candidate who emphasized his “story,” Obama argued that what he lacked in experience with foreign affairs he made up for with foreign travel: four years in Indonesia as a boy, and trips to Pakistan, India, Kenya, and Europe during and after college. But there was no mistaking the lightness of his résumé. Just a year before coming to Washington, State Senator Obama was not immersed in the dangers of nuclear Pakistan or an ascendant China; as a provincial legislator, he was investigating the dangers of a toy known as the Yo-Yo Water Ball. (He tried, unsuccessfully, to have it banned.)
In Pakistan in 1981, Obama stayed at the estate of the man who was recently caretaker Prime Minister after his boss, Gen. Musharraf, quit. Although Obama recently boasted of how much foreign policy expertise he gained from this trip, he didn't mention it in Dreams from My Father since it didn't have much to do with his story of race and inheritance.
Obama's youthful connection to Pakistani bigshots is not particularly remarkable. Imagine an American student at Amherst in the 19th Century who makes friends with the tiny number of Italian students there, and goes to visit Italy with his classmate. His friends would almost certainly belong to a politically influential network of Italian families. Of course, if that American later ran for President, it would be interesting to know which network of Italian families he had connections to. ...
Obama's Pakistani friends no doubt came from wealthy, influential families within Pakistan. Does anybody know what their political connections are within Pakistan, since they've probably helped shape Obama's view of that complicated and obscure part of the world?
The Cave of Forgotten Dreams is the latest documentary from artiste / showman Werner Herzog. It's cinema's first look at the world’s oldest known cave paintings (c. 30,000 B.C.), discovered in 1994 at Chauvet Grotto in southeastern France and immediately locked up to protect the stunning drawings of imposing beasts.
The French government allowed Herzog to make this first documentary about Chauvet because he is a major auteur. His long career depicting energetic lunatics includes 1972’s Aguirre: The Wrath of God, in which a 16th-century conquistador searches in vain for a city of gold amid Brazil’s fever swamps.
You and I will never be allowed in Chauvet.
Osama bin Laden’s fortress was heavily constructed–drone-proofed, it seems, when built in 2005. He avoided land-lines and stayed indoors. This is consistent with the need to evade the US and its technology. In contrast, his compound was very lightly guarded. This is consistent with a high degree of comfort–concerning the possibility of a ground raid.
Of course bin Laden discounted the chance of a US commando raid–anyone would have (in fact, that loud racket you hear is the sound of the president’s giant brass b**ls clanging together as he does his victory lap). There was no need to post a useless armed contingent whose presence could only draw suspicion. If and when we came it would be via airborne munitions.
What is striking is how completely bin Laden appears to have discounted the possibility of being raided by Pakistani forces. What confidence he had in the fidelity, authority and discretion of his benefactors, whoever they are!
"Indeed, evidence suggests that quality of teaching is the most important non-demographic contributor to student learning."
Pentagon officials said they were preparing for calls for a more rapid withdrawal from Afghanistan.
Pentagon officials acknowledged that NATO nations, many of whom already are reluctant to remain in Afghanistan, also may argue that Bin Laden’s death allows them to withdraw more rapidly than planned.
“I hope people are going to feel, on a bipartisan basis, that when you move the ball this far it’s crazy to walk off the field,” one senior administration official said. Officials who favor retaining a large troop presence said that while this was a significant victory, the security gains in Afghanistan remained fragile.
We Got Him.
Abbottabad, the city where Osama bin Laden met his death on Sunday, has a long history dating from the days of British rule as a military station. It remains today the headquarters of a brigade in the Second Division of Pakistan's Northern Army Corps, and is dotted with military buildings and home to thousands of army personnel. The Associated Press says the house where bin Laden died is just 100 yards from a Pakistani military academy.
It was a magnificent run. From the end of the Second World War to the mid-1960s, California consolidated its position as an economic and technological colossus and emerged as the country’s dominant political, social, and cultural trendsetter. … In 1959, wages paid in Los Angeles’s working-class and solidly middle-class San Fernando Valley alone were higher than the total wages of 18 states.
It was a sweet, vivacious time: California’s children, swarming on all those new playgrounds, seemed healthier, happier, taller, and — thanks to that brilliantly clean sunshine — were blonder and more tan than kids in the rest of the country. For better and mostly for worse, it’s a time irretrievably lost. …
Starr consistently returns to his leitmotif: the California dream. By this he means something quite specific — and prosaic. California, as he’s argued in earlier volumes, promised “the highest possible life for the middle classes.” It wasn’t a paradise for world-beaters; rather, it offered “a better place for ordinary people.” That place always meant “an improved and more affordable domestic life”: a small but stylish and airy house marked by a fluidity of indoor and outdoor space … and a lush backyard — the stage, that is, for “family life in a sunny climate.” It also meant some public goods: decent roads, plentiful facilities for outdoor recreation, and the libraries and schools that helped produce the Los Angeles “common man” who, as that jaundiced easterner James M. Cain described him in 1933, "addresses you in easy grammar, completes his sentences, shows familiarity with good manners, and in addition gives you a pleasant smile."
Until the Second World War, California had proffered this Good Life only to people already in the middle class — the small proprietors, farmers, and professionals, largely transplanted midwesterners … But the war and the decades-long boom that followed extended the California dream to a previously unimaginable number of Americans of modest means. Here Starr records how that dream possessed the national imagination … and how the Golden State — fleetingly, as it turns out — accomodated Americans’ “conviction that California was the best place in the nation to seek and attain a better life.” …
This dolce vita was, as Starr makes clear, a democratic one: the ranch houses with their sliding glass doors and orange trees in the backyard might have been more sprawling in La Canada and Orinda than they were in the working-class suburbs of Lakewood and Hayward, but family and social life in nearly all of them centered on the patio, the barbecue, and the swimming pool. The beaches were publicly owned and hence available to all — as were such glorious parks as Yosemite, Chico’s Bidwell, the East Bay’s Tilden, and San Diego’s Balboa. Golf and tennis, year-round California pursuits, had once been limited to the upper class, but thanks to proliferating publicly supported courses and courts (thousands of public tennis courts had already been built in L.A. in the 1930s), they became fully middle-class. This shared outdoor-oriented, informal California way of life democratized — some would say homogenized — a society made up of people of varying attainments and income levels. These people were overwhelmingly white and native-born, and their common culture revolved around nurturing and (publicly educating) their children. Until the 1980s, a California preppy was all but oxymoronic. True, the comprehensive high schools had commercial, vocational, and college-prep tracks (good grades in the last guaranteed admission to Berkeley or UCLA — times have definitely changed). But, as Starr concludes from his survey of yearbooks and other school records, “there remained a common experience, especially in athletics, and a mutual respect among young people heading in different directions.”
To a Californian today, much of what Starr chronicles is unrecognizable. (Astonishing fact: Ricky Nelson and the character he played in that quintessential idealization of suburbia, The Adventures of Ozzie and Harriet, attended Hollywood High, a school that is now 75% Hispanic and that The New York Times accurately described in 2003 as a “typically overcrowded, vandalism-prone urban campuse.”) Granted, a version of the California Good Life can still be had — by those Starr calls the “fiercely competitive.” That’s just the heartbreak: most of us are merely ordinary. For nearly a century, California offered ordinary people better lives than they could lead perhaps anywhere else in the world. Today, reflecting our intensely stratified, increasingly mobile society, California affords the Good Life only to the most gifted and ambitious, regardless of their background. That’s a deeply undemocratic betrayal of California’s dream …
