Back to School special

Oraculations has a posting for all you public school teachers out there:

After being interviewed by the school administration, the teaching prospect said, "Let me see if I've got this right: You want me to go into that room with all those kids, correct their disruptive behavior, observe them for signs of abuse, monitor their dress habits, censor their T-shirt messages, and instill in them a love for learning. You want me to check their backpacks for weapons, wage war on drugs and sexually transmitted diseases, and raise their sense of self esteem and personal pride. You want me to teach them patriotism and good citizenship, sportsmanship and fair play, and how to register to vote, balance a checkbook, and apply for a job. You want me to check their heads for lice, recognize signs of antisocial behavior, and make sure that they all pass the state exams.

You want me to provide them with an equal education regardless no matter their handicaps, and communicate regularly with their parents by letter, telephone, newsletter, and report card. You want me to do all this with a piece of chalk, a blackboard, a bulletin board, a few books, a big smile, and a starting salary that qualifies me for food stamps. You want me to do all this and then you tell me...


I CAN'T PRAY?"

My review of James R. Flynn's What Is Intelligence? Beyond the Flynn Effect

On VDARE.com I offer the first review of the new book on the Flynn Effect by Flynn himself:


Despite hysterical politically-motivated attacks on them that have sometimes turned violent, researchers into human intelligence have by now produced a coherent and compelling scientific picture, as explained in books such as the 1994 best-seller The Bell Curve by Richard Herrnstein and Charles Murray.

With one exception.

For uncertain reasons, all over the world, raw IQ scores have been rising, on average at the rate of about 3 points per decade. Thus, a test performance that a half century ago would have ranked at the 84th percentile (a score of 115) now is only good enough for the 50th percentile (a score of 100).

When IQ test publishers revise and renormalize their exams every decade or two, they have to make scoring tougher to make the mean stay at 100.

This is very strange. One of the more dubious-sounding implications is that if you go far enough back into the past, the average person would have been a complete dolt, and the greatest genius of that earlier age would have been no smarter than George W. Bush or John Kerry.

Rising test scores were pointed out by Reed Tuddenham in 1948, when he compared the better performance on the U.S. military's IQ tests of the draftees of WWII compared to WWI.

In the early 1980s, James R. Flynn, an American-born political scientist at the University of Otago in New Zealand, began to call this phenomenon to academic and then public attention. In his honor, in The Bell Curve, Herrnstein and Murray christened rising IQ scores the "Flynn Effect".
...

Mainstream IQ researchers, who are used to being demonized when they are not being ignored, admire Flynn, who is politically a man of the left, for his fairness, geniality, insight, and devotion to advancing knowledge. The Flynn Effect has often been seized upon to dismiss IQ testing in general, especially by race-deniers who assume that it will cause racial gaps in IQ to converge out of existence. Flynn himself, however, has never joined the mob in unfairly attacking psychometrics—or psychometricians.

Nevertheless, the Flynn Effect did leave Flynn skeptical about IQ tests. Ulric Neisser wrote in The American Scientist in 1997: "Flynn concludes that the tests do not measure intelligence but only a minor sort of 'abstract problem-solving ability' with little practical significance."

But Flynn has now written a book offering his considered explanation of the Flynn Effect: What is Intelligence? Beyond the Flynn Effect. (The Psychometrics Centre at Cambridge University has posted online a lecture by Flynn summarizing his book.)

Strikingly, Flynn has changed his mind. He now sees the Flynn Effect not as undermining IQ testing, but as validating it. After decades of reflection, Flynn believes people really are more intelligent in some ways today — just as their raw IQ scores suggest. The reason: we get more mental exercise now than in olden times. [More]

If this AP "news" article had been an online debate, Godwin's Law would have been invoked in the first 100 words.

The Associated Press reminded us on Saturday, September 1, the 68th Anniversary of Nazi Switzerland's invasion of
Poland, that the Swiss are still a bunch of Nazis. Let us never forget how the Swiss Nazi juggernaut steamrollered across Europe and is just waiting to pounce once again:


Swiss deportation policy draws criticism

By FRANK JORDANS, Associated Press Writer
Sat Sep 1,
8:17 AM ET

GENEVA - The campaign poster was blatant in its xenophobic symbolism: Three white sheep kicking out a black sheep over a caption that read "for more security." The message was not from a fringe force in Switzerland's political scene but from its largest party.

The nationalist Swiss People's Party is proposing a deportation policy that anti-racism campaigners say evokes Nazi-era practices. Under the plan, entire families would be expelled if their children are convicted of a violent crime, drug offenses or benefits fraud.

The party is trying to collect the 100,000 signatures needed to force a referendum on the issue. If approved in a referendum, the law would be the only one of its kind in
Europe.

"We believe that parents are responsible for bringing up their children. If they can't do it properly, they will have to bear the consequences," Ueli Maurer, president of the People's Party, told The Associated Press.

Ronnie Bernheim of the Swiss Foundation against Racism and Anti-Semitism said the proposal was similar to the Nazi practice of "Sippenhaft" — or kin liability — whereby relatives of criminals were held responsible for his or her crimes and punished equally.

Similar practices occurred during Stalin's purges in the early days of the
Soviet Union and the 1966-76 Cultural Revolution in China, when millions were persecuted for their alleged ideological failings.

"As soon as the first 10 families and their children have been expelled from the country, then things will get better at a stroke," said Maurer, whose party controls the Justice Ministry and shares power in an unwieldy coalition that includes all major parties.

He explained that his party has long campaigned to make deportation compulsory for convicted immigrants rather than an optional and rarely applied punishment.

The party claims foreigners — who make up about 20 percent of the population — are four times more likely to commit crimes than Swiss nationals.

Bernheim said the vast majority of
Switzerland's immigrants are law-abiding and warned against generalizations.

"If you don't treat a complicated issue with the necessary nuance and care, then you won't do it justice," he said.

Commentators have expressed horror over the symbolism used by the People's Party to make its point.

"This way of thinking shows an obvious blood-and-soil mentality," read one editorial in the
Zurich daily Tages-Anzeiger, calling for a broader public reaction against the campaign.

So far, however, there has been little popular backlash against the posters.

"We haven't had any complaints," said Maurer.

The city of
Geneva — home to Switzerland's humanitarian traditions as well as the European headquarters of the United Nations and the U.N. Refugee Agency, or UNHCR — said the campaign was likely to stir up intolerance.

The UNHCR said the law would run contrary to the U.N. refugee convention, of which
Switzerland is a signatory.

But observers say the People's Party's hardline stance on immigration could help it in the Oct. 21 national elections. In 2004, the party successfully campaigned for tighter immigration laws using the image of black hands reaching into a pot filled with Swiss passports.

"It's certainly no coincidence that the People's Party launched this initiative before the elections," said Oliver Geden, a political scientist at the Berlin Institute for International and Security Affairs.

He said provocative campaigns such as this had worked well for the party in the past.

"The symbol of the black sheep was clearly intended to have a double meaning. On the one hand there's the familiar idea of the black sheep, but a lot of voters are also going to associate it with the notion of dark-skinned drug dealers," said Geden.

The party also has put forward a proposal to ban the building of minaret towers alongside mosques. And one of its leading figures, Justice Minister Christoph Blocher, said he wants to soften anti-racism laws because they prevent freedom of speech.


Clearly, their support for freedom of speech proves that Nazi blood still runs thick in Swiss veins.

What we're really interested in

Science is in the business of making predictions, but the better it gets at predicting anything, the more boring those predictions are for us. For example, I predict that the sun will set at the O'Hare Airport in Chicago today at 7:26 pm CDT. When you think of all the effort that has gone into astronomical observation and prediction over the millennia (for example, Stonehenge), that's an incredible feat the human race has achieved to be able to accurately predict that.

It's also phenomenally boring.

Now, here's a different prediction: Republican nominee Mike Huckabee will outpoll Democratic nominee Bill Richardson 51%-47% in the November 2008 Presidential election. "What an idiot!" you say, "Don't you know that the Clintons will stop at nothing to get back to the White House? Richardson and Huckabee? You don't know anything about the election!" And you're right. I don't. I'm not even sure where Huckabee is from. I think it's that state, you know, the one you drive through to get to that other state.

Now, here are some more predictions. USC will not finish #1 in college football this season. Instead, Rutgers will bring the national title home to Delaware. (Or maybe to Connecticut, depending on where, precisely, Rutgers is located. Assuming it's located somewhere. Maybe it's like the DeVry Institute and is located everywhere. But I digress.) On the other hand, USC will win the NCAA basketball championship next spring behind frosh sensation OJ Mayo.

"What a jerk!" you exclaim, "Everybody knows that USC's linebacking corps is the most devastating in college football since Penn State's back in 1987." Well, I don't know that. In fact, I know barely anything about college football these days.

But the point is that, unlike the sunset forecast, these predictions are interesting, as brainless as they are. The reason that making up nonsense off the top of my head about elections and sports is interesting is because nobody can predict accurately sports and far-off elections with a lot of candidates. Sports, especially, are designed to be hard to predict just so that they will keep our interest. The same with gambling. Randomness isn't natural in the world, at least above the subatomic level. It takes a lot of work to develop gambling devices that are close to random, but a roulette wheel is more interesting than betting when the sun will go down because it's hard to predict.

You often hear that the social sciences aren't real sciences like astronomy because they can't predict anything. But that's not true. Indeed, I'll make a social science prediction for 25 years into the future. I predict that in the year 2032, the students at the schools in Beverly Hills will enjoy higher average scores on statewide and nationwide standardized tests than the students at schools in Compton. Anybody want to bet against me?

I've got a million more predictions like that. For example, in 2032, the children of today's unskilled immigrants will be more of a burden on society than the children of today's skilled immigrants. (That seems like an important use of social science -- to make predictions extremely important for choosing the optimal immigration legislation, right?)

"Well, sure," you say, "Of course. But those predictions are boring. And depressing. In fact, it's in bad taste to mention things that we all sort of know are true but that we really don't want to think about. Who wants to hear predictions like that? Tell us something interesting."

Okay, on December 31, 2032, the Dow Jones Average will stand at 107,391. But just one year later it will have crashed, in the wake of Black Wednesday, all the way to 33,828. But by 2042, during the bubble following a major breakthrough in cold fusion, the Dow will have reached the 201,537 barrier.

"Now that's better! That's the kind of prediction we like: specific and exciting. Of course, you're probably just randomly punching numbers on your keypad, but we forgive you because you're not boring and depressing us anymore."

Designer color names

One of the challenges faced by fashion designers is coming up with new names for the same old colors. For example, here is a sandal whose strap color an unfashion-forward individual like myself might describe as "blackish" but a professional designer describes as "Ballistic Anthracite." What the hell is that? It sounds like a weapons system from one of those sci-fi alternate histories of the Civil War in which the War Between the States finally ends in 1887 when Pennsylvania wipes out Virginia's fleet of steam-engine tanks with a salvo of coal-powered missiles.

Carol M. Swain

My new VDARE.com column is a review of the anthology she edited:


Yale Law School Professor Peter H. Schuck observes:


"In a polity in which only 17 percent of the public thinks that immigration levels should be higher and 39 percent thinks they should be lower, one would expect that at least some legal scholars who write about immigration issues would favor restriction. If so, one would be wrong. In over two decades of immersion in immigration scholarship, I have not encountered a single academic specialist on immigration law who favors reducing the number of legal immigrants admitted each year." ...


So, Carol M. Swain, a law and political science professor at Vanderbilt, has done the academic world a service (although one it probably won't appreciate) with her new book Debating Immigration. She brings together 16 chapters from academic and think tank luminaries such as Nathan Glazer, Amitai Etzioni, Douglas S. Massey, and Steven A. Camarota, along with lively essays from journalists Peter Brimelow and Jonathan Tilove.

Swain
is one of the more unusual and admirable scholars in public policy. Growing up black and poor in rural Virginia, one of twelve children, she dropped out of 9th grade and married at 16. In her mid-20s she started back to school. Eventually, she earned tenure at
Princeton as an expert on how Congress operates.

Her views are difficult to categorize politically. I would say she's an advocate of black enlightened self-interest, left of center on economics, right of center on culture. For example, her 2002 book The New White Nationalism sensibly advocated depriving white nationalists such as Jared Taylor of their best issues by restricting immigration and cutting back on affirmative action, especially for immigrants and affluent blacks. Needless to say, that hasn’t happened.

Top 5 scientists ever?

Anthropologist John Hawks offers some good suggestions:


Don't get me wrong, I like physics as much as anybody. But once your list includes Newton, Einstein, and Maxwell, and then you throw in Galileo, well there's not much room for anything else. None at all if you take Darwin as a given.

So I decided to do something a little different: What five scientists have had the greatest impact on human life? Yes,
Newton was great, but gravity goes on without him.

Many later discoveries stood on his shoulders, but
Newton's achievements were far more intellectual than practical. I'm looking for people whose accomplishments saved lives, prevented wars, stopped hunger, or released people from endless drudgery. This isn't a list of inventors -- if it were, there would be a lot of ancient inventions like the moldboard plow that deserve more attention than anything modern. It's a list of scientists whose impact stretched across many fields, and without whom life today would likely be worse.

1. R. A. Fisher. His work in population genetics laid the foundations for the vast productivity increases of twentieth-century agriculture. He was far from alone in this, but he stood apart from his contemporaries by inventing many of the statistical methods that would come to define scientific hypothesis testing. Without Fisher's innovations in statistics, large-scale medical research studies would be meaningless. All this after he established the basis for Mendelian inheritance of continuous characters.


Fisher strikes me as the Newton of the 20th Century: the scientist / mathematical innovator.

Will the NYT ever report anything bad about their blogger Steve Levitt?

Here's the abstract of a paper in press by economist Ted Joyce, followed by Joyce's cogent explanation of why it's important to keep harping on this subject.


A Simple Test of Abortion and Crime
Ted Joyce
Baruch College and Graduate Center
City University of New York
and
National Bureau of Economic Research

Forthcoming in Review of Economics and Statistics

A Simple Test of Abortion and Crime

Abstract

I replicate Donohue and Levitt’s results for violent and property crime arrest rates and then apply their data and specification to an analysis of age-specific homicide rates and murder arrest rates. The coefficients on the abortion rate have the wrong sign for two of the four measures of crime and none is statistically significant at conventional levels. In the second half of the paper, I present alternative tests of abortion and crime that attempt to mitigate problems of endogeneity and measurement error. I use the legalization of abortion following the 1973 decision in Roe v. Wade in order to exploit two sources of variation: between-state changes in abortion rates pre and post Roe, and cross-cohort differences in exposure to legalized abortion. I ind no meaningful association between abortion and age-specific crime rates among cohorts born in the years just before and after abortion became legal.

I. Introduction

The debate as to whether legalized abortion lowers crime leaped from academic journals to mainstream discourse with the huge success of Freakonomics.1 In the Chapter titled, “Where Have All the Criminals Gone?” Levitt and Dubner summarize academic work by Levitt and coauthor John Donohue, which shows that a one-standard deviation increase in the abortion rate lowers homicide rates by 31 percent and can explain upwards of 60 percent of the recent decline in murder.2 If one accepts these estimates, then legalized abortion has saved more than 51,000 lives between 1991 and 2001, at a total savings of $105 billion. But the policy implications go beyond crime. If abortion lowers homicide rates by 20 to 30 percent, then it is likely to have affected an entire spectrum of outcomes associated with well-being: infant health, child development, schooling, earnings and marital status. Similarly, the policy implications are broader than abortion. Other interventions that affect fertility control and that lead to fewer unwanted births—contraception or sexual abstinence—have huge potential payoffs. In short, a causal relationship between legalized abortion and crime has such significant ramifications for social policy and at the same time is so controversial, that further assessment of the identifying assumptions and their robustness to alternative strategies is warranted.


The New York Times more or less sets the agenda for the rest of the news media. If the NYT decides a story is fit to print, much of the the rest of the press will soon decide, what do you know!, that the topic deserves coverage. But if a tree falls in the forest and the NYT doesn't cover it ... This means the NYT has a particular responsibility to avoid giving in to conflicts of interest, which they have clearly succumbed to over the last two years in their refusal to report on any of the controversies swirling around their star columnist turned blogger Steven D. Levitt.

Graduate Record Exam scores by graduate field of study

A reader sends along this table from the Graduate Record Exam from ETS giving average scores by intended field of study in grad school. He includes an estimate of IQ from one of the popular conversion tables, although he didn't tell me which one.

One problem I saw was that the mean score for the Quantitative section is so much higher than for the Verbal section, and the standard deviation is also larger for Quant, that the combined scores were biased in favor of highly quantitative fields. So, I added three more columns on the right that show difference fro the mean in standard deviations and just take the average for verbal and quantitative compared to their separate means. That seems fair, since there's no evidence that verbal intelligence correlates lower with general intelligence, and it may well be the best surrogate for the g factor. So, that's how I sorted it, which moves philosophy up into second place behind physics.

That reminds me of how I wrote a review of a book by David Stove in 1999 making gentle fun of philosophy (well, maybe not that gentle: I referred to the "uselessness of philosophy"). I received a number of superbly articulate and intensely argued emails telling me I didn't know what I was talking about. You'll notice I've drawn in my horns on this topic ever since!

This table may not be fair to business students since perhaps the better ones tend to take the GMAT to apply to MBA schools.
