New research into IQ levels could end the modern taboo on comparing cleverness, says Michael Hanlon
We accept that some people are taller than others, or darker- or lighter-skinned, or better at running. We also accept that these differences are due, at least in part, to genetics. Yet there is one area where we continue to insist that there cannot be any innate biological distinction between different people, or groups of people, and that is in our minds. The merest suggestion that there may be hard-wired disparities in intelligence causes the most terrible wailing and gnashing of teeth, even though such physical and mental variations – dictated by genes and environment – are exactly what you would expect in an abundant species that has adapted to just about every corner of the globe.
That taboo, however, may be breaking down. In his new book, the brilliant psychologist James Flynn, of Otago University in New Zealand, has revealed that, for the first time, women (in some developed countries) are systematically outperforming men in standardised tests of intelligence. This contradicts earlier findings which suggested that, historically, men have had IQs that were a couple of points higher – or rather, have performed marginally better on a whole slew of intelligence metrics, which measure subtly different things.
The reaction to this finding has been largely positive. Most reports have concentrated on women’s ability to “juggle” and to “multi-task”, with the conclusion: “Didn’t we know this all along?” Expect to hear the old clarion call of “men are redundant”, with the human male reduced to a shambling, knuckle-dragging brute lost in a sea of feminised modernity.
Imagine, however, that Flynn had found the opposite. Suppose that his trawl of standardised measures of intelligence in schoolchildren and young adults, in countries as disparate as Estonia, Argentina, Israel and New Zealand, had confirmed, once and for all, that men had slightly higher IQs. Would that finding be celebrated?
Of course not. Howling columnists would queue up to pour scorn on the very notion, stating that the idea of innate sex differences in IQ is utterly chauvinist. Others would take issue with the whole notion of measured intelligence: “What is IQ,” they would ask, “but a measure of the ability to do intelligence tests?”
Either way, it is important to stress that the differences we are talking about are very small, a percentage point or two at most – and whatever the truth, it’s not as though we can do much about it. The more interesting question is not whether women are cleverer than men, but why this should be so, and why this seems to be a recent trend.
First, we have to dismiss the pernicious but persistent fallacy that IQ is meaningless. The tests used today attempt to measure something called g, a measure of innate general intelligence that is divorced, as far as possible, from cultural and social bias. Thus questions tend to involve not word associations (which are influenced by your level of literacy and knowledge) but connections between patterns and shapes, order and structure.
Most psychologists now accept that while IQ (or g) may not be a measure of pure intelligence per se, it is certainly a measure of something that correlates very well with it. People with high IQs tend to end up with better qualifications, better jobs, higher earnings and longer lives. Crucially, they are also perceived as “cleverer”. Like it or not, being a successful human has a lot to do with being smart – and IQ, or g, does seem to be a fair measure of smartness.
This brings us to one of the most interesting – and scientifically counter-intuitive – findings to have emerged in the last 100 years: namely, that we are all, men and women alike, getting brighter.
The trend was discovered by, and named after, Flynn himself back in the 1980s. In industrialised countries, both adults and children are routinely subjected to various IQ measurements. And, since such testing began in the first half of the 20th century, the average IQ of both sexes has risen by between 10 and 20 per cent. Every few years, the tests had to be revised to make sure that the average score remained at 100 – and in every country, that revision meant making the tests harder.
This means that if a British child scores 100 on an IQ test set in 2012, he would score 110 or so on a test dating from the 1970s. In some countries, such as the Netherlands, where the Flynn Effect was first spotted, the increase has been even more spectacular – a full 30 IQ points between 1950 and 1980. Overall, IQ in both industrialised and developing nations is rising by about three points per decade.
For years, the cause of the Flynn Effect was a mystery. One thing it could not be was genetic: the effect is happening too fast for any form of evolution to be occurring. Better diet was a popular theory, but places like the US, Canada and Scandinavia have been well-fed for a century or more. Education may have been a factor – but again, the increases continued well into the era of compulsory universal schooling in most countries.
In the end, it was Flynn himself who solved the mystery. The effect, he argued, is not due to innate changes in our brains, but to how they react to the sort of problems that define the modern world. Flynn gives an example: “If I were to have asked my father, say, 'What do a dog and a rabbit have in common?’ and then ask the same question today of a bright schoolchild, I would get two answers.” His father, like most “old-fashioned” people (Flynn is in his eighties, so his father was a product of the 19th century) would look for associations. “Dogs hunt rabbits,” he might have said – which is not wrong, but nor is it the answer to the question.
Today, any schoolchild would give the “right” answer, namely: “they are both animals” or “they are both mammals”. Flynn’s point is that until recently, this categorising of the world, putting things into boxes – mammals or not-mammals, dollars or pounds, Apples or PCs – was not the way people thought. In this sense IQ, or rather differences in IQ, may not be so much a measure of intelligence as of modernity.
It is this that may give us a clue as to why women are not only catching up with men but, in some places, starting to overtake them. There may be something innate about the way women’s brains are put together (or the demands placed upon them) that allows them to cope with complexity and the need to systematise. As Prof Flynn said at the weekend: “In the last 100 years the IQ scores of both men and women have risen, but women’s have risen faster. This is a consequence of modernity. The complexity of the modern world is making our brains adapt and raising our IQ.”
Many mysteries remain about human intelligence. Will the Flynn Effect continue, so that our grandchildren look down upon us as barely sentient dullards? Or will it go into reverse, as dysgenic effects (the fact that people with lower IQs tend to have more children) take over? Will the developing world continue to catch up with the old industrialised world? Why do men continue to outperform women in intelligence tests in non-industrialised societies?
Some of this research may be controversial. After all, if talking about sex and IQ is tricky, talking about race and IQ is incendiary: as with high-IQ women, we are generally happy to talk about certain ethnic groups (such as some Jewish populations) having high IQs, but less happy with the corollary, namely that others are less well endowed.
Yet in an increasingly knowledge-driven world, where brains are more important than brawn to a degree never seen before, we need to understand these differences, if for no other reason than to help raise everyone to their potential. Being scared to talk about it is – well, just stupid.
The above article is informative and well-argued and it is pleasing to note that it appeared in a major British newspaper. On some matters of detail, however, I have to differ.
Flynn's argument that we have only recently started to categorize is absurd. Every noun in our language stands for a category of things. Categorization is a central human survival strategy. It enables us to make predictions and thus protect our futures to some extent. Even cavemen would have readily detected the difference between a dog and a rabbit, for instance (to use the example above). Their hunting trips would have had little success otherwise. Expecting a rabbit to help you bring down prey would be pretty futile.
So what alternative do I offer to Flynn's explanation? I agree with him that modernity generally is the explanation but I differ on which aspects of modernity are involved. One aspect is increasing test sophistication. As education has become more widespread and extended into the late teens, kids have developed strategies for passing tests (guessing when uncertain, for instance) and those strategies help with IQ tests too. A test of that explanation is that the rise in IQ should now be levelling off as just about everybody now is exposed to a lot of education. And that does indeed appear to be happening in some countries. The Flynn effect appears to be fading. IQ levels seem to be approaching an asymptote, in statisticians' terms.
But there are other aspects of modernity that are presumably important too -- improved peri-natal care, for instance and also childbirth itself. Babies can quite easily be brain-damaged to varying degrees during birth and the much increased use of episiotomies and Caesarians would obviate a lot of that. So more babies are born with their brains functioning to their maximum potential.
So what do I make of the current slightly higher scores of women in some countries? For a start, it is perfectly easy to design a test that will show either sex as brighter. Women have better verbal skills and men have better visuo/spatial skills so if you want to show women as brighter you put in more verbal questions and if you want to show men as brighter you put in fewer verbal questions. So it is possible that recent re-standardizations of tests have added more items in areas that women are good at.
Another possibility is the way the educational system has become anti-male, with female characteristics praised and male characteristics deplored. This has led to extensive alienation of young males and a much higher educational dropout rate among them. In such circumstances, then, males get on average less opportinity to acquire that test sophistication I referred to above. We live in a feminized environment generally, in fact, compared to (say) 100 years ago so there may be many ways in which females are subtly advantaged.
The important point, however, is to recognize that people do differ in many ways and that, like it or not, IQ is one difference that affects a lot of things that we value. High IQ, for instance, is associated with greater wealth and better health while low IQ is associated with higher levels of crime and greater poverty. -- JR
Fatal Misstep for Obama as he abolishes work requirement for welfare recipients
Until this week, the Obama campaign's strategy of interest group payoffs and demonization of Romney seemed, if tawdry, at least a possible route to re-election. The president's promises to deliver more and more "free" stuff for carefully selected grantees -- adorned in the language of sticking up for the "middle class" -- appeared to have a chance of success.
But the decision to embrace one of the least popular Democratic positions of the past 100 years -- opposition to the work requirement for welfare recipients -- is inexplicable politically. It's also illegal and imperious. Let's stick with politics, because it's old news that Obama has contempt for the rule of law. He's declined to "take care that the laws be faithfully executed" on many subjects: immigration, the Defense of Marriage Act, labor laws and environmental rules, among others. Those were lawless but politically logical acts. Not this.
Welfare policies (along with weakness on defense and crime) had been a vulnerability for Democrats throughout the 1970s and 1980s -- an Achilles heel that Bill Clinton recognized in 1992. His promise to "end welfare as we know it" was the gravamen of his claim to "new Democrat" status. Once safely elected, Clinton downgraded welfare reform, and, in fact, increased funding for all of the traditional welfare programs in the federal budget. But when Republicans gained control of the House of Representatives in 1994, they took the initiative. By 1996, after vetoing two welfare reform bills, Clinton was advised by Dick Morris that if didn't sign the legislation, he wouldn't be re-elected; it was that important to voters. Immediately after signing the bill, Clinton's approval rating on welfare jumped by 19 points.
The law changed the old AFDC, Aid to Families with Dependent Children, to TANF, Temporary Assistance to Needy Families. In place of the open-ended entitlement to benefits for unmarried women and their children, the law imposed a five-year limit and the requirement that those able to work seek employment. In 2005, the work requirements were strengthened.
The prospect of asking welfare recipients to seek work struck most liberals in 1996 (including Obama) as degrading, cruel and doomed to failure. Three high-ranking Clinton administration officials resigned in protest. The New York Times called the reform "atrocious," objecting that "This is not reform, this is punishment." Tom Brokaw, interviewing the president, said "all the projections show that ... (the reform) will push, at least short term, more than a million youngsters ... below the poverty line." The Children's Defense Fund called the law "an outrage ... that will hurt and impoverish millions of American children ... and leave a moral blot on (Clinton's) presidency." Sen. Daniel P. Moynihan called the law "the most brutal act of social policy we have known since the Reconstruction. ... In five years' time, you'll find appearing on your streets abandoned children ... in numbers we have no idea." Sen. Edward Kennedy, with characteristic understatement, called the bill "legislative child abuse."
Well, what really happened? Welfare caseloads declined by 50 percent within four years of the law's passage and by 70 percent by the time Obama took office. The overwhelming majority of those who left welfare rolls did so because they found jobs -- and not just the worst jobs, either. By 2001, a Manhattan Institute study found, only 4 percent of former welfare mothers were earning minimum wage. The poverty rate declined from 13.8 percent in 1995 to 11.7 percent in 2003. Black child poverty dropped to its lowest levels in history. Childhood hunger was cut in half. It was the greatest social policy success of the past 50 years.
Yes, the late 1990s were boom years for the economy. So had the 1960s and 1980s been. Yet welfare rolls increased during those previous expansions.
Why did Obama do it? Why issue new regulations from the Department of Health and Human Services (in bold violation of the law) granting waivers to states to alter work requirements? Obama's election notwithstanding, there is little reason to think that the nation has moved left on the welfare issue. Most working Americans, including most poor Americans, believe that paying people for idleness is wrong.
Obama is trying to persuade Americans that while he has expanded food stamps to unprecedented levels, extended unemployment insurance to 99 weeks, vastly increased the already overwhelmed Medicaid program, created a new trillion dollar entitlement with Obamacare and expanded the size of the federal government to a percentage of gross domestic product not seen since World War II, that he is not the dependency president. By stepping back into history to embrace the Democrats' nemesis -- unrestricted welfare -- he has clinched the argument for the opposition.
83% Support Work Requirements for Welfare Beneficiaries
Good call, Mr. President
Most Americans think there are too many people on welfare who should not be getting it and believe overwhelmingly that those who do receive welfare benefits should be required to work.
A new Rasmussen Reports national telephone survey finds that 83% of American Adults favor a work requirement as a condition for receiving welfare aid. Just seven percent (7%) oppose such a requirement, while 10% are undecided. Support for a work requirement is slightly higher among those who personally know someone who is receiving welfare benefits.
In other words, only 7 percent of those polled in the Rasmussen survey would support the Obama administration’s directive to “gut” President Clinton’s welfare reform law. Wonderful. Incidentally, Guy wrote about this topic yesterday, speculating why the White House -- in the middle of an election year -- would single-handedly unravel a hugely successful (bipartisan) compromise that Americans overwhelming support. (Click through and draw your own conclusions, but his analysis certainly makes sense). More to the point, though, could the president be any more out of touch? He’s made an alarming amount of “gaffes” over the last few months, none of which were more galling than when he actually asserted – to an audience of entrepreneurs, mind you -- that “if you've been successful, you didn't get there on your own.” Smart.
Unsurprisingly, his comments have sparked genuine outrage across the country to the point where even Mitt Romney seems fired up. Tim Pawlenty, a campaign surrogate rumored to be on the governor's VP shortlist, released this succinct statement earlier today.
Mitt Romney’s got a very different view that features the private sector and entrepreneurial activity. The President’s comments the other day were stunning, they were jarring, saying that businesses didn’t contribute or didn’t do it themselves or words to that effect. Let’s debate those two competing visions for the future of this great nation and quit messing around with these collateral issues.
And so it begins?

The Big Lie of the late 20th century was that Nazism was Rightist. It was in fact typical of the Leftism of its day. It was only to the Right of Stalin's Communism. The very word "Nazi" is a German abbreviation for "National Socialist" (Nationalsozialist) and the full name of Hitler's political party (translated) was "The National Socialist German Workers' Party" (In German: Nationalsozialistische Deutsche Arbeiterpartei)
