entropic_existence: draypresct: Do you have a link? The decreasing trend in math scores doesn't match what I've been able to find.

Using NAEP scores (figure 2 of link), there has been a general upward trend in math, while reading ability has either increased or remained relatively constant in the US since 1971. It's difficult to interpret the trend, since I'm not familiar with the units used in NAEP scores (is a 5-point difference a lot?), but it's certainly evidence that there hasn't been an overall decline.

Oh, and my guess for "why have IQ scores been increasing" is nutrition/willingness to educate the poor/more resources available (books, computers, etc.) across the economic spectrum*/the concept that education isn't just "stand up in front of the room and recite a memorized poem/fact/whatever"/immigration policies that bias towards highly-qualified people entering the country/etc.etc.etc.

It was based solely on the Numerical Reasoning portion of the IQ tests, so it would likely overlap but not be identical to NAEP scores I would assume. And my bad, the study that showed a decrease in numerical reasoning was in Norwegians not the United states. (http://www.sciencedirect.com/science/article/pii/S0160289604000522  )

If you look at even the wiki entry for the Flynn effect a lot of your ideas are all considered part of it. People go to school for much longer on average now than ever before, we eat better, and more adults are in cognitively demanding jobs (cognitively demanding compared to stock manual labour that is).


Thanks for the link (although I'm wondering if they've introduced bias by limiting their analysis to conscripts - the pool of Norwegians entering the armed forces over the years isn't necessarily constant).

I agree that the other factors you named play a role as well - we're talking about  lots and lots of inter-related factors, not a single cause with a simple narrative explanation.

doglover: LasersHurt: Could it be that health and nutrition, especially early in life, are hugely important?

Not as much as you'd think.

More likely IQ tests are just a fairly bad measure of real intelligence. That's why there's strong cultural biases.


Unless you get a high IQ score, then IQ tests are made of God's own golden sciencey Truth, and only stupid people question them, because they're envious.

Norway technically has a form of mandatory military service. While not everyone actually gets conscripted for service (making it in practice basically voluntary), all able-bodied men of conscription age have to meet before the draft board where they undergo psychological and intellectual examination. It makes Norway a pretty great source for the data because they are a developed nation and you get the majority of 18-20 year old men undergoing evaluation. It's introduces the least amount of sample bias possible.

CrazyCracka420: Being able to find information on Google doesn't make us more intelligent.  Just easier to find that information.


This is true, but having the information available gives you something else to think about. Being able to compare information from different sources gives you something else to think about. Reading critiques of information from different sources gives you even more to think about. This process can help you exercise something that looks remarkably like intelligence.

A hundred years ago, a typical school might have had a single shelf of books - maybe. A few (*ahem*) decades ago when I was a young'un, the typical source of information was the (note the singular)encyclopedia. There is a lot of information in an encyclopedia, but we're talking about something with all of two whole paragraphs on topics like "Taiwan" (OK "Formosa" back then) or "The Ottoman Empire" or "Aerodynamics". Even for those few children who might have the extra time and energy to look up confirmatory or conflicting sources, most topics only had a single source of information (if you were lucky!).

While there were a few heretics like Feynman or Heinlein (or my father) who corrected books when they were wrong, most people just went with what a book said. The effort required for information access led to a focus on memorization, not critical thinking.

I recall reading a study last year that said nearly all of the increase is in the spatial/perceptual parts of the test, relatively little in the math parts, and almost none in the language. One hypothesis is that our widespread exposure to media and technology is much better practice for those parts of the test than previous generations received.

I hadn't known that about Norway's conscription process. Thanks!

That does reduce or eliminate* the bias.

/*My only quibble on "eliminate" is that I don't know offhand if the definition of "able-bodied men of conscription age" has remained the same and had the same effect over the years. This is probably not something that had any real effect over the past couple of decades, though, so the study's conclusions are probably accurate.

Mostly diet.

Good nutrition is very important from conception to early childhood. Most of the brain's growth occurs very young. Humans have the largest brains at birth of many species, including our primate cousins.

Malnutrition has been shown to have epigenetic effects on your grandchildren. Women born during famines in Sweden had grandchildren with more health problems. Even men inherit health problems from their grandfathers as well as their mothers, although the Mother's contribution is vastly greater because it is the Mother who provides the mitochondria, the powerhouses of the cell and the only organelle that has its own DNA.

In the 1800s, women ate very badly. Men ate first in working households, and women were taught to pick at their food. Women did not eat enough meat and were more prone to diseases such as tuberculosis, even in rich households.

With better maternal care before birth and better child care after birth, children simply weren't as brain-damaged after health care reforms were introduced.

Safe milk, formulated baby foods, and general health produced most of the rise in IQs.

Many other factors play a big role, such as enriched environments, better education in childhood, reduction in poisons in the home (asbestos, mercury, lead paint, etc.).

One big factor is diseases which cause mental retardation. These are rampant in tropical and sub-tropical environments. The US South was (and remains) a whole lot stupider than the North simply because of disease and parasites as well as rotten public health care, welfare, and education. Even today, things like ringworm are more common among the poor and Southerners. They have not been eliminated the way that polio and smallpox have. In Africa, it can take eight weeks or more to teach servants to do simple jobs that a normally intelligent working person would only need to be shown or told how to do once. Sleeping sickness and other diseases cause some of this retardation, malnutrition causes much of it. Even a few pennies of vitamins given to pregnant women could increase the intelligence and productivity of the African poor by similar large percentages as have been observed in the rich world and among the rich and middle classes in the poor world.

But number one is what the Mothers and enfants eat and how much.

Prior to the development of scientific medicine and vast numbers of studies and experiments, many done on very large populations such as students or soldiers, they simply did not know what the body needed for optimal growth.

Racists ignore all of this evidence of the perfectibility of man. They attribute intelligence to "blood" when it is more likely to be produced by "milk", especially Mother's milk, which can produce a difference of almost five degrees--about the difference between American whites and blacks.

Then again, there are people who claim that we are dumber than our Victorian ancestors. They base this on studies of certain mental attributes that seemingly have declined. But they are probably mistaking changes in the constitution of high school classes for innate properties.

The drop out rate has declined as legislators have legislated school attendance and supplied the resources necessary for students to learn and even eat in some cases.

As the French say, Ventre affamé n'a point d'oreilles (A hungry stomach has no ears.) I love that saying. It just sounds great. It's also very true.

It is likely that we have not seen the end of rising intelligence. It is needed more than ever and our health, security and prosperity depends more and more on intelligence being applied by all people in all situations.

Doesn't matter if you're retarded if your work is manual and you can't afford guns, cars, university attendance, etc. But if you are retarded in a highly technical and intellectual environment, your stupidity is as contagious as Bart Simpson's naughtiness and will produce what Principal Skinner called a cone of ignorance around you.

One bad apple spoils not only the whole barrel, but possibly the whole crop.

But intelligence probably follows a logistic curve. These are s-shaped curves that resemble exponential curves but are slow to rise at the beginning and end of the curve.

Intelligence is largely a product of material circumstances (in the body and in the environment). Karl Marx, Engels, Lenin and Stalin all understood this as is pointed out by the great British physiologist and geneticist, J.B.S. Haldane, who was an idealistic and intelligent Communist despite being fooled by the Russian con for a long time. Conservatives often do not acknowledge the connections between the material world and the mental world and thus moralize when they should supply a comfortable living wage and social welfare benefits to all.

You can't be very smart on a bad diet, with an impoverished social and cultural environment, and while riddled with debilitating disease. Even the more intelligent Conservatives have realized that some support is required to prevent the poor from dragging us all down. You can't steal everything a man has or else you lose the worker who makes you so fecking superior and rich. Workers are a form of capital, like land, industrial plant, and technology. They can be upgraded to think as well as to work better.

jso2897: Race mixing. As humans become "mongrelized", we will get smarter and healthier, just like dogs do - diversity is the key to genetic success.


My father confided to me in 1978 that I wasn't all white: he was part Native American and part Black, from his mother's side.

He said he didn't have documented proof and it wasn't easy to find, given that in that area in that time one's "race" was a social definition as much as blood-quantum thing: if your community agreed you were White that's how you were treated and recorded. E.g., someone like Homer Plessy could go from White to Colored or vice versa by moving a couple dozen miles where his family wasn't known; in many cases is still true, given blue-eyed people with African facial features and very curly "dirty blond" hair who call themselves Lumbee Indians when they could just as easily "qualify" as White or Black when away from home.

Then he set out to find proof of his racial ancestry anyway, which wasn't very productive, and later on I tried my hand at genealogy. It was cool to trace my paternal ancestry back to the Ulster Plantation and discover that I'm descended in part from Jonathan Swift's grandmother, though disquieting to find that 300 years ago a couple ancestors or their siblings owned slaves. On his mother's side I couldn't find much, except that at least one of her ancestors owned at least one slave too; they were all recorded as White. Despite even that I couldn't however find any proof that I'm partly descended from slaves or even Blacks, though I probably have Black 5th & 6th cousins.

Meanwhile I spat in a tube and got my DNA tested: according to 23andme I'm 99.99% White European (with
"0.1% Unassigned"), mostly British (partly Celtic) on my father's side and central German (Sassanach!) on my mother's just like the genealogical records show, and though somehow I got to be 2.6% Neanderthal they didn't find any markers for any "non-White blood."

It was a big blow finding out at age 49 that what my father told me about my race 25 years earlier was probably incorrect, that after a lifetime of regarding myself as "legally Negro" I have to get used to being "totally Caucasian." So my medium-high IQ didn't come from visibly traceable mongrelization: it might as well have been a Gypsy curse. ("137!") It's always worked out that way too: instead of being an improvement on something previous, or even a degeneration from an earlier genius strain, it's made me orthogonal -- a mutant, a farking freak. I even had to drop out of 8th grade, after a very rocky grade school history, because I was tired of being bullied & beaten for not trying harder to hide that I got good grades and enjoyed reading. (It would have been nice to have had the social intelligence to learn "protective coloration," dammit.)

Anyway. To must bring these comments back into line with the thread, IIRC the last Mensa pretest I took was far less "culturally White" than the ones they gave me in the '70s, which might account for the drop in IQ from 160+ to a mere 137: maybe it's not that I'm all that smart, just pretty bright for a White guy. (*rimshot*)

In any case it'd be an expensive struggle to get into Mensa now: first I'd have to prep my body/brain by getting enough sleep etc., then I'd probably have to download and take several sample/practice tests, and the proctored test would cost $40 I'd rather spend on whiskey. Even then there's no guarantee I wouldn't flop totally or just barely squeak in with such an embarrassingly low score that I'd be out-geniused by everybody else. At age 50 yet.

2013-10-11 11:38:03 AM  

grimeystubs: I am calling BS. I have seen on the internet schoolhouse exams for 6th graders from the golden age of America individualism that show people were much smarter back then. This was of course due to the non-liberal education that has transformed America in to a bunch of commies or something.

How many bushels are 3 hogsheads again?


Not true. During the Golden Age of Bootstrapy, only a small percentage of the wealthiest families sent their children to school even as far as the sixth grade. These people are still smarter than the average today, only not so much so because the average person is, despite a crooked system, smarter relatively and absolutely than they were. This is a filtered and distorting way to look at intelligence.

Furthermore, even those who went to school were forced to work harder than today because relatively speaking, time was more valuable. When life-expectancy was 40-45 years in the US, and children had lower life expectancies, they were forced to learn more of the basics, sooner. They were not distracted by school sports, TV, radio, computers, video games, or even a lot of light reading. It was noses to the grindstone.

If you truly believe that exams prove that our ancestors were smarter, you would have to acknowledge that they prove that third world students are smarter because they too have their noses to the grindstone and beat our Western students on math, science, and anything remotely practical, such as engineering, while being lousy at many luxury skills such as creative thinking and problem-solving rather than rote-learning.

The Chinese educational system is very 1800s in its concentration on making money or giant leaps forward. Their health care and environmental regulations are similarly typical of America during the Robber Baron Age.

Teachers have been getting lazier and students also, so they may teach less and learn less in a unit of time. But the average student lives to be dumped into college or the job market today. Back then, only the brightest and the luckiest made it through grade school, so they had to learn all they were going to learn in grade school or become auto-didacts and teach themselves as youths and adults.

And then consider how much less there was to know. If you only have to learn half as much, you can learn that half better. If you only focus on the skills and knowledge necessary to get rich or to build an economy up fast, you can focus better.

Conservatives are, well, conservative and they love anything old-timey, supposing that former days were better than these. But as the Bible says, it ain't necessarily so. Ask not why former days were better than these, for thou doest not inquire wisely after such things. That's word, Brother!

I have a great book entitled The Good Old Days, They Were Awful! which describes early industrial America in unromantic and very accurate terms. Very little of the milk that American infants and children drink today is Malk. Very little of it is chalk-coloured water. In China and elsewhere, because they don't have liberal and progressive government agencies such as the FDA, children die because the milk they are being fed by their loving parents is fake.

This is a tragedy, and also something that needs to be considered when you compare exams from 1890 to exams from 2013.

Oysterman: It's not mentioned, so I'm going to assume if you score us against modern norms, we would have an average IQ of 65.


No, the median is always 100. That's how the scoring is set up: half of the American testees score under 100 and half score over 100. It's like a standardized dollar. It is always 100 cents, although over time it may buy more or less.

In fact, intelligence measurements are very like economic measures of quantities that change over time. They are difficult but informative. You really have to think hard to understand what the numbers really mean.

I'm fairly certain this is a nature vs nurture thing. Poor nutrition for most people caused severe limitations on growth, both physical and mental. Wealthy, well-nourished people of the 1800s had already reached their genetic potential.
 
2013-10-11 11:55:01 AM  
As a child I lived in a small rural village. This has provided me with all kinds of knowledge and insight that even people smarter or more informed than myself do not have.

In a small village you see all the classes of society at once, and they are very well known to you. You are forced to associate with everybody whether you like them or not, want to have anything to do with them or not.

And that's why Brantgoose is such a genius at this comparative stuff. A deprived upper middle class childhood enriched with information and experiences that you'd have to live one hundred lives to acquire in normal circumstance.

I also like to say that I have had the good luck to live in three or four different centuries. In this same small village I was exposed to ideas, people, things and activities that pretty much cover everything from the 1700s to the 2000s.

Some of our quaint rural customs would not have been strange to our 13 times great grandparents.

And being of French and British and other stock, I have been exposed via my genealogy with a lot of history and culture, not to mention a lot of genes.

A recent study by a Quebec University has taken advantage of the almost unique high quality of genealogical records and modern DNA techniques and has discovered that there has been a very surprising amount of evolution going on in Quebec. Although the small original population has left a powerful legacy in the population as a whole, with Quebecois sharing most of the same genetic background as their French ancestors, there has been a surprising amount of mixing and sorting going on.

In short, we are an exceptionally fast-evolving population thanks to small pockets of inbreeding which causes genetic abnormalities, some of which are adaptive. If you understand evolution well, you can see how this might be very valuable.

I'm a lucky pappy in many ways. My material circumstances have made my intellectual circumstances rare if not unique.

I should probably have studied the humanities instead of literature and language, but hey, you spend more of your life "unemployed" than working. Between vacations, weekend, after-work hours, and retirement or unemployment, I thought it would pay better to follow my heart and read, read, read.

I haven't a lot of money (more than most, but not a lot) but I have had a lot of time to read, to think, to write enormously over-length Fark posts, and to argue with stupid and bright people alike.

You can learn a heck of a lot from arguing with a semi-retarded idiot.

But as Farkers, you know that instinctively, don't you?

Trust me. Intelligence is one of the things that intelligent people understand least. They are soaking in it up to the points on their giant heads. It's lovely and complicated though, and thus a lot of fun.

For example, the authors of this paper (  http://www.nber.org/papers/w19233 ) posit that iodization of salt accounts for a big chunk of the IQ increase.  The effects are large enough to account for one decade of the Flynn effect.

That plus removing lead from gasoline (and other toxic chemicals from everyday use) you get your IQ boost. We would also have a malnutrition epidemic today if we didn't fortify grains with B vitamins and Milk with vitamin D.

We also force parents to send their kids to school and we do it for free. We also force the kids to stay in school until age 16 (depending on state), both of my Grandfathers dropped out of school in 6th grade.

A simpleminded estimate: Let's assume that the authors correctly adjusted for all the other temporal trends occurring between WWI and WWII (their pre- and post-iodine comparison sample) and that iodine has accounted for one decade's worth of the Flynn effect since 1920.

The paper was written 9 decades after 1920, so we would conclude that iodine accounts for 1/9 of the improvement. Simple!

Good luck explaining the improvement in NAEP math scores since 1970 in terms of improved nutrition, though.

I expect that nutrition is just one factor out of many that has influenced the rise in intelligence in the US.

Dinobot: Our brain process a lot more information, just from a single source. 

A certain color, a certain tune,  and/or a certain font can evoke a specific brand...

Compare the first trailer of Die Hard with Die Hard 5...

The original Die Hard needed a narrator to walk us through, giving us bullet points of what the movie is about. 

The latest Die Hard trailer only needs to have Ode to Joy playing while a door opens to quickly evoke the scene with Hans Gruber as they finally open the safe in the original movie, instantly telling us "THIS IS A DIE HARD MOVIE"


I see you listened to the cracked podcast on the Flynn effect for that precise analogy.

endosymbiont: As a number of people said, +nuitrition and -lead. That's all you need.


That's right, the only two things the twentieth century did to improve IQs are +nutrition and -lead. And the increased schooling.

The only three things were +nutrition, -lead, +schooling, and reduced inbreeding.

Well, yes, reduced inbreeding, ok. So the only four things were +nutrition, -lead, +schooling, -inbreeding, and -infectious diseases during development. Of course we've reduced serious infections; nobody needs to mention that!

I've got this: the only things were +nutrition, -lead, +schooling, -inbreeding, -infection, and increased exposure to abstract concepts.

Right! So, aside from +nutrition, -lead, +schooling, -inbreeding, -infection, and +exposure to abstract concepts, the twentieth century has done nothing for improving IQs. Agreed?

Some 'Splainin' To Do: Doc Daneeka: But but....Idiocracy.  I've been assured by a million people on the internet that people are getting inexorably dumber over time.

Idiocracy is excellent satire, but it's bad science. Population genetics don't work like that.


I know. I was being sarcastic regarding the people who seemingly regard Idiocracy as gospel truth.

People are always ready to intuitively believe that people are getting dumber, culture is getting more degraded, each generation is lazier, ruder, and more self-centered. These claims usually happen amidst pining for "the good old days." This fretting about society's decline has been going on for thousands of years.

But it's not supported by facts. The "good old days" sucked. And history is full of barbaric, violent, selfish, incultured, uneducated, illiterate, and downright dumb people.
