The Smart Are Getting Smarter and More Girls Are Good At Math

A new article, "Studying Intellectual Outliers: Are There Sex Differences, and Are the Smart Getting Smarter?," in Current Directions of Psychological Science by a trio of Duke University researchers looks at what is happening to IQ and math ability scores at the highest end of the IQ distribution - the top 5 and to 0.01 percent, respectively. About three decades ago, New Zealand political scientist James Flynn found that average IQ scores were increasing at a rate of 0.33 points per year. The Duke researchers find that IQ scores at the high end are basically increasing in line with the overall general trend.

The researchers also wanted to see if there were sex differences in math and verbal scores. An earlier study that looked at the students who scored in the top 0.01 percent on SAT-Math found the male-to-female ratio was 13.5 to 1. Their data finds that that ratio shrank to 4 to 1 and has remained more or less stable for the past two decades. They conclude:

The fact that we continue to find sex differences in math ability within the very smartest group means that sex differences in math ability are likely part of the explanation for female underrepresentation in high-level math and science careers.

They stress that math ability is a small part of the explanation. Looking again at the top 0.01 percent on the verbal tests they find:

These ratios primarily favored females, ranging between one and two females for every male, and like the gender ratios for math ability scores, they also appear to have been stable across time.

With regard to overall IQ score trends in the top of the distribution, they find:

Using multiple measures from the SAT, ACT, and EXPLORE tests, we examined whether the Flynn effect occurred for the intellectual outliers (i.e., the top 5% of scorers). Overall, the effect appeared to be concentrated on the measures of math (or nonverbal) ability, with small gains or no gains on the other measures. The gains on these measures of math ability (amounting to an increase of 0.33 IQ points per year) are similar to the average rate of gain found in studies focusing on the general distribution; therefore, this right-tail finding links directly with the broader literature on the general population....

These findings demonstrate for the first time that scores among the entire distribution (including the right tail) have risen at a relatively constant rate. The Flynn effect may also explain why an increased number of gifted students has been identified in recent years: Gifted programs often have cutoff scores that do not change over time, which may correspondingly lead to a higher proportion of students attaining that cutoff score.

What is boosting IQ scores among the smartest? The Duke researchers speculate:

We think our findings suggest that enhanced cognitive stimulation may play a role in the right-tail gains. For example, the rise of digital culture and video games may be involved.

Play video games - it's for the kids!

    True story: I did a science project in 7th or 8th grade to test whether playing video games helped increase reaction time. When it came down to the day the assignment was due, I had played too many video games and forgotten to do the study, so I did the "pencil drop test" about 10 times and counted that as my findings. I think I got a B.

    But there is nothing wrong with our school system!!!!!11!11!1

    In 11th grade, I didn't feel like preparing a speech I had to do because I had an undiagnosed concussion at the time. So I winged it and rambled through 4 minutes about Sports Illustrated swimsuit models. I got a D+. PASSING.

  • Bam!||

    In the 4th grade, I flat out didn't read the book and then had to give a presentation, in front of the class, on said book. I simply froze and the teacher let me hang there for like 5 minutes. But then she gave me a C+.

    And I didn't read the fucking book.

  • Free Society||

    I showed up to science fair with an array of moldy bread I found in my cupboard the day before. I got 3rd place.

  • Jack the Reaper||

    I shot off Estes rockets at my 6th grade sciense fair.

    I also learned new ways of spelling science.

  • Auric Demonocles||

    I also shot off Estes rockets, in the mid 90s. I was "investigating the effect of temperature on model rocket engines".

    I did spell science correctly, as back in those days we had a thing called spell check.

  • Jack the Reaper||

    Spell checking in the 80's involved a heavy, bound book called a dictionary.

    I had a college course on public speaking. One time I never got around to preparing my speech, and so gave an improvised speech on procrastination.

Luckily, the teacher let me give a prepared speech during the next class.

    I haven't noticed the kiddies being smarter, really, but there seems to be an ever-increasing number of psychotic, overbearing parents who basically force their children to study relentlessly at the expense of a normal childhood.

  • AlmightyJB||

    The saddest thing to me is that kids aren't free to just take off and explore and play. They cannot leave their parents sight. When I was a kid I would be up Saturday morning at the crack of dawn, hop on my bike and be gone. That freedom was great.

    Everyone is getting smarter at the same rate so kids wouldn't seem smarter to you. However, the theory is that kids today are smarter than kids of the same age were ten years ago. I'm kind of surprised actually that the helicopter parent effect hasn't lowered their scores. Or maybe it has but it's offset enough by kids with normal parents.

    Smart does not necessarily mean wise either. Kids may be smarter but they may also be just as ignorant as every generation before them.

    What is this "normal childhood" of which you speak?

    Kids can't play outside anymore. I mean, too many kids playing in your lawn and you're getting sued for being an unlicensed daycare. If a kid falls down and hurts themselves on your property you could get sued. Can't make a fort or a tree house without a building permit. Can't ride a bike without a dorky helmet. Besides, there's a pedophile around every corner.

    These days a "normal childhood" consists of video games and studying. What else is there for a kid to do?

There was one time that someone told me they couldn't go out drinking because they had an exam in 2 weeks they needed to study for, literally 5 minutes after we finished an exam.

    Smart people are smart. I am friends with smart women who are engineers, and I am friends with a dumb (but handsome) male masseuse. I went to high school with a very smart girl who majored in Math in college. She was a statistician for awhile, but decided to pursue a career in art. I went to college with a guy who was a brilliant punk rock bassist. He chose to pursue a career in statistics, and now has a PhD and is highly published. My point is...

    From http://en.wikipedia.org/wiki/Order_of_operations

    For example, in mathematics and most computer languages multiplication is done before addition; in the expression 2 + 3 × 4, the answer is 14. Brackets, "( and ), { and }, or [ and ]", which have their own rules, may be used to avoid confusion, thus the preceding expression may also be rendered 2 + (3 × 4), but the brackets are unnecessary as multiplication still has precedence without them.

    However, the causes for these gains and whether they reflect real gains in intelligence continue to remain a mystery.

    They're pretty obviously caused by children studying more for standardized tests. And no, that doesn't count as a raise of the general factor.

  • pmains||

    Sidd says it's obvious, so obviously no other solution is possible. All of the "teaching to the test" propaganda is entirely true and no discussion is necessary. Move along.

  • $park¥||

    A friend of mine is trying to become a teacher and his mother is a teacher. The whole "teaching to the test" thing gets trotted out every time we talk about school.

  • Sidd Finch||

    The following is from some guy named James Flynn. Not sure if he knows much about the Flynn Effect.

    Similarly, some people are more gifted at words than at numbers, or vice versa, and therefore, factor analysis yields secondary factors such as a verbal factor, a quantitative factor, a spatial reasoning factor, a speed of information processing factor, and so forth. These factors are often called 'latent traits' and defined as the core things IQ tests measure. When you analyze IQ gains over time, you often find that they do not constitute enhancement of these latent traits -- they go not seem to be general intelligence gains, or quantitative factor gains, or verbal factor gains (Wicherts et al, in press). In the language of factor analysis, this means that IQ gains over time tend to display 'measurement artifacts or cultural bias'. For a second time, we are driven to the conclusion that massive IQ gains are not intelligence gains or, indeed, any kind of significant cognitive gains.
    http://search.bwh.harvard.edu/.....tDraft.doc

  • pmains||

    Valiant effort. I still give you an F.

    From the same document:
    The 20th century has seen us go from subjects who have never taken a standardized test to people bombarded by them and undoubtedly, a small portion of gains in the first half of the century were due to growing test sophistication. However, its role has been relatively modest.

    Nowhere else in the document does he discuss standardized testing.

    So, to review, you made an assertion about "teaching to the test." You cite a paper that doesn't actually support your claim, although it does discuss other things that tangentially relate to your point. I don't dispute that Flynn believes that the way we think is changing and that that accounts for IQ gains. I was aware of that before your post. That does not mean that "teaching to the test" is the culprit.

  • Sidd Finch||

    You keep quoting "teaching to the test." It's unclear if you think I actually said that, or anything like it. Do you deny that kids study more for the SAT? Do you deny that studying for the SAT increases SAT scores? Do you think the SAT is a full-scale IQ test?

    The quote from Flynn was to back my assertion that test score improvements aren't g-factor improvements, which is what matters for people who aren't professional test takers.

  • pmains||

    OK. You said "studying more for standardized tests." Happy? It's another way of phrasing the same whining we hear from teachers all the time about standardized tests affecting the way they teach, which is why it grated me when you said it.

    The problem is that you haven't shown causality, or why the causality is obvious or indisputable. Maybe studying for SATs and other standardized tests is what's causing the rise in test scores. Then again, maybe sitting in a classroom for 12 or more years that emphasizes certain types of learning has a little something to do with it.

    If I had to wager, I would say that studying for standardized tests is a rather small part of the picture.

  • Sidd Finch||

    Here's my issue with SAT research. In general, the Flynn Effect is odd. Why in the hell did people get so much better at mentally rotating 3D objects? It's a helluva mystery. I can think of lots of reasons, and maybe some or all of them played a part. But it's just guessing.

    OTOH, why did people get better at taking the SAT over a period when standardized testing was ubiquitous during K-12 and college admissions became much more competitive? That answer seems obvious to me.

    I thought the same thing but gave them the benefit of the doubt and assumed they were comparing SAT scores after they had already sorted out the top IQ test scorers.

    Perhaps, but even so, as a skeptic of a singular g, this study just gives me more evidence that psychometrics for IQ give too much weight to math ability.

    psychometrics for IQ give too much weight to math ability.

    That's not how factor analysis works.

  • Heroic Mulatto||

    I realize that. I was just making a general statement concerning my skepticism of the existence of a singular g factor. Indeed, most days, I'm not convinced that g itself exists. In my opinion, we just don't understand enough about the modularity of the brain and the mind and don't understand enough about how different cognitive abilities correlate to one another to accurately define what g is.

    However, I find current research in mental chronometry in CogSci to be encouraging, and perhaps a metric that is better suited to finding g, if it exists.

    Just my informal two cents in a much greater, hotly debated academic conversation.

    I took the Mensa entrance exams last year. I don't think even 1/3 of the total test was math related, and even what was was mostly basic arithmetic with a speed component. I'm not sure how they convert their test scores to IQ though, and I've never taken a standardized IQ test so I'm not sure how they compare. In any case, it doesn't seem like there was too much dependence on math ability.

    Shit, Sparky, I think you just said arithmetic was a subset of math. But that can't be, can it?

  • $park¥||

    Arithmetic is like the zygote that grows into the fetus that is math.

  • Sidd Finch||

    Math isn't all that g-loaded. The most g-loaded subtest is usually vocabulary, which strikes me as really weird.

    I'm including all that spatial rotation business into "math".

  • $park¥||

    OK, that would bump it over 1/3 but still below 1/2.

  • Heroic Mulatto||

    I see. While I have never taken the Mensa test, I have taken both the Stanford-Binet and the Wechsler. The S-B was much more math heavy than WAIS in my experience.

  • Sidd Finch||

    IIRC SAT IQ correlation is about .75. IQ g correlation is about .95

  • Heroic Mulatto||

    IQ g correlation is about .95

    Is that for all standard IQ tests (Stanford-Binet, Weschler, etc.) or just one of them?

  • Sidd Finch||

    I had to search pretty hard in my brain basement to come up with those two numbers. Further digging suggests a sentence something like "the typcial correlation between a full scale IQ test and the g-factor is .95."

  • Heroic Mulatto||

    Interesting. I'll have to do some digging myself when I have some free time tomorrow.

    "The fact that we continue to find sex differences in math ability within the very smartest group means that sex differences in math ability are likely part of the explanation for female underrepresentation in high-level math and science careers."

    This raises an important scientific question:

    Do we burn these heretics at the stake, or hang them, or burn their intestines in front of them before cutting them into four pieces?

  • $park¥||

    All of that, just make sure you follow the correct order of operations.

    Why? They've conclusively proven that Marilyn vos Savant must be a tranny.
