The research suggests that genes aren't what's driving the decline in IQ scores "It's not that dumb people are having more kids than smart people," researcher says
(CNN) — IQ scores have been steadily falling for the past few decades, and environmental factors are to blame, a new study says. The research suggests that genes aren't what's driving the decline in IQ scores, according to the study, published Monday. Norwegian researchers analyzed the IQ scores of Norwegian men born between 1962 and 1991 and found that scores increased by almost 3 percentage points each decade for those born between 1962 to 1975 -- but then saw a steady decline among those born after 1975.
Similar studies in Denmark, Britain, France, the Netherlands, Finland and Estonia have demonstrated a similar downward trend in IQ scores, said Ole Rogeberg, a senior research fellow at the Ragnar Frisch Center for Economic Research in Norway and co-author of the new study.
Researchers have long preferred to use genes to explain variations in intelligence over environmental factors. However, the new study turns this thinking on its head. Intelligence is heritable, and for a long time, researchers assumed that people with high IQ scores would have kids who also scored above average. Moreover, it was thought that people with lower scores would have more kids than people with high IQ scores, which would contribute to a decline in IQ scores over time and a "dumbing down" of the general population, according to Rogeberg. Anyone who has seen the film "Idiocracy" might already be familiar with these ideas. In the scientific community, the idea of unintelligent parents having more kids and dumbing-down the population is known as the dysgenic fertility theory, according to Ritchie.

The study looked at the IQ scores of brothers who were born in different years. Researchers found that, instead of being similar as suggested by a genetic explanation, IQ scores often differed significantly between the siblings. "The main exciting finding isn't that there was a decline in IQ," Ritchie said. "The interesting thing about this paper is that they were able to show a difference in IQ scores within the same families." The study not only showed IQ variance between children the same parents, but because the authors had the IQ scores of various parents, it demonstrated that parents with higher IQs tended to have more kids, ruling out the dysgenic fertility theory as a driver of falling IQ scores and highlighting the role of environmental factors instead. What specific environmental factors cause changes in intelligence remains relatively unexplored
Juan Garcia
> "The interesting thing about this paper is that they were able to show a difference in IQ scores within the same families." looks like it's an environmental effect. perhaps something with the diet changed?
Kevin Morgan
This couldn't possibly be correlated with changing demographics. And to even suggest such would be extremely xenophobic.

>Rogeberg yeah this study's gonna get a no from me
Stop eating and drinking fluoride and estrogen fueled drinks/ foods. Which is already controlled and all over the market. But that's just a small speck of what's causing the decline.

What's changed in the last few decades? Oh yeah, they've went from 5 or so vaccines to telling you you've got to pump your baby full of toxins in 30+ shots while their still in infancy and having brain development.
>we let in a bunch of garbage and our IQ went down Gotta be pretty low IQ if you can't see the correlation.
Jaxson James
dont twins have similar IQs though?
Sebastian Evans
Stop watching cnn
John Walker
>show a difference in IQ scores within the same families
unless these were twin studies it says very little about the strong link of genetics to IQ This paper is another foothold in an attempt to decouple genetics from intelligence and therefore promote a social constructionist agenda that relies on people being blank slates
Asher Thompson
it's not a concrete theory. I have an IQ of 124 and my parents have an IQ of 100.
We stopped putting real iodine in our salt. We now use iodide. /thread
Joseph Cox
to be honest i think its cultural
iq tests are heavily impacted by overall ambition and people just don't seem to care as much anymore about anything really
perhaps its due to our lives being too easy and all the power has been taken away from the people so nobody feels any compulsion to really strive for anything no need to everything they need to live can be gained with absolute minimal effort some dont even need to leave their house anymore they can just work from home and have their food delivered not to mention all the entertainment they could ever need it at there fingertips at any given moment
Carter Ross
>"The interesting thing about this paper is that they were able to show a difference in IQ scores within the same families." This doesn't mean anything. Unless you can show a statistically significant decline across all hereditary lines broken down by birth dates in a sufficiently large sample, they're blowing smoke. Families are not uniform.

Brown people breeding, at ever exceeding rates, coupled with stale white and asian birthrates and boom, down goes collective i.q.

The countries you cite are too damn comfy for young people. 1) They don't have to pay for an education. In fact, some of those countries will pay students to go to school. 2) They don't need to look hard for work. Apprenticeships are available. The wages are not bad. Worst case scenario, you get NEETbucks from welfare state.
3) You've got European parenting, liberal schools and no borders/cheap travel.
The younger generations have it easy in those nations. You don't need a high IQ to survive or live well.
Jayden Barnes
That can be a component the decline- see Simpson's paradox. But the researchers said they observed this effect occurring within a given family. White IQs specifically are lowering, not just the general population.
William Reyes
The mid 70s is when divorce and single motherhood became more normalised and prevalent. Single motherhood and divorce are known to lower test scores of children raised in these homes and alter brain chemistry

Lack of destitution breeds dumber people. We need actual war, meaningful war, every 40 or so years. It's not great, it's our penance; we wanted knowledge and this is the price. Don't pay it and we lose it.

Stupidity used to be deadly as fuck. It isn't anymore. Airbags were the last straw. Car accidents used to be the last reliable way to weed out the idiots.
Nicholas Lee
This and also most rigorous academic work is really dumbed down and easy now. 8th graders used to study Latin and read the classics, now college freshmen read the cliff notes of the classics and are told they are only considered great because they illegitimately inflate white men's egos. If you dont develop your brain, you wont have as high of an IQ.
Angel Allen
Of course you would have significant iq differences within families. Siblings have large genetic differences, despite being more similar to each other than they are to random strangers. This article is written by someone who doesn't understand genetics, or purposely intends to misrepresent the data to push more of a blank slate idea.

It keeps getting worse to the point where my University has also had to lower some standards, and they can't admit many domestic students because they're all retarded unless they had private education of some sort.

No corrilation....

Wow! You mean subsidizing nigger and beaner reproduction while suppressing white reproduction drops the aggregated global IQ?
Ryder Brooks
>and they can't admit many domestic students because they're all retarded unless they had private education of some sort. Oh and all the domestic students they admit are Chinese because those are the only people who actually make their kids learn things anymore. I'm often the only white guy in a room of 20-30 of them.

we all know it though, it's the niggers
Brayden Sanchez
>"It's not that dumb people are having more kids than smart people," It's just that we've been importing ~60 IQ retards from the third world.

Kayden Harris
I see, so you're talking about the environmental effect of demographic change rather than just the directly genetic. Fair enough.
Isaac Gray
Reduce income tax. Remove social benefits.All immigration must be > Avg country IQ and from cultures have no taboo on intermarriage between faith / race and do not practice arranged marriage. Set a 120 IQ minimum on Sperm banks and gov funded fertility treatment. Allow transfer of tax free allowances between couples. Allow women to bank annual tax free allowances from years when on maternity. Enrich flour with iodine again and reduce fluoride. Ban artificial sweeteners. Have another war - casualty rates are significantly higher for lower IQ.
Course none of these will happen, as the reduction is entirely intentional.
The more palatable way is to cap benefits and housing, and only provide gov benefits for 1st child and the rest are in the form of tax incentives only. If you aren't paying your own way you don't have kids. House prices need to come down 50%, same with university fees if you want to get smart people to have more kids.

Correlation literally never equals causation.
Gavin Watson
Yea, here's the answer. It's obvious to everyone on Jow Forums already:
It's called reversion to the mean. High IQ niggers come in from the third world, and their kids are retarded. No surprise it started happening soon after we started importing 3rd world nigger retards for slaves.
Jaxson Phillips
Western societies are currently dysgenic so that doesn't disprove it
Chase Bailey
It is non-white immigration. But it is not just it, low IQ natives have more kids that high IQ natives, thanks to socialism.

What could it be? No way of knowing for sure. Better just to turn me on and stare at me for several hours a day, it'll take your mind off those pressing concerns. Besides you had a hard day, you're tired, you're stressed, you worked really hard, you exercised earlier, you don't feel like reading, it's too hot to do anything else, it's too cold to do anything else, you just want to chill and relax, you don't want to miss your shows, it helps you unwind. >Come along with me, my friend for the most glorious sensation youtube.com/watch?v=SrgMkez5bS8

Given a healthy brain, the potential for IQ is based on socio-environmental factors.
Anthony Morales
Make life hard enough to require a higher IQ. What we have no requires nothing but brainlet slaves to the State, why would our IQ be higher, why wouldn't our IQs be declining? It's just not necessary from a survival standpoint.
Another problem is the IQ test itself, and how it purports to measure innate ability, yet some people have provably cheated IQ tests and others have improved their scores with preparation and experience. This means the IQ test is bunk and the decline in "IQ" can easily be correlated to the decline in education since the State took over curriculum, but more especially since the State began creating idiots. We're all fucking stupid, conditioned for postmodernist gratification-obsession, if you can't admit that to yourself you're just a little more stupid than the rest of us.
Gabriel Campbell
No we don't. At least not when controlled for race. Or at least there is no data for it. All the data for this study was from the military recruitment IQ tests of various countries, including the inter-family data.
It's useless.
Cameron Howard
That doesn't mean intelligence isn't largely heritable, it just means that you're ~1.6 SDs above your parents' mean IQ, which is well within the realm of possibility.
All the heritability estimates say is that the set of 1000 children of parents with a mean IQ of 130 will have a higher average IQ (something like 18 points higher, I believe) than the set of children of parents with a mean IQ of 100. Genes just set the base rates, probability does the rest.
Gavin Martin
>corrilation Ironic.
Brody Reed

this is completely wrong, the poor and stupid are having the most children. what fucking country was this study done in?
their sample group is fucked, because this is just plain wrong in the big picture

hypersexual media + mixed classrooms + social movements that "liberate" the goyim = lower IQ yes
Charles Flores
kids used to play tetris and solve puzzles now they watch bullshit and eat trash food with no omega 3's I FUCKING WONDER WHY
Joseph Johnson
OP, the article refuses to state how IQ was measured. It refuses to state whether the measurements were calibrated to other IQ tests. It refuses to name a single reference IQ test that would have been used to calibrate the others if any IQ test the article mentions had been calibrated to any other test (the article doesn't mention calibrating IQ tests so it is pure speculation that any IQ test the article mentions was calibrated to any other IQ test)
>global warming didn't work to piss people off >now we're going to tell them they're stupid
1. IQ 2. global warming these are CNN-tier subjects the point of these subjects is the news media will use them for pure hysteria any insight or remark or observation that might interfere with getting a hysterical reaction is ignored or suppressed cable news network more like cable hysteria network CHN
Mason Hall
CNN learns about regression to the mean
Matthew Bell
you're retarded, genes actually play a far larger role in intelligence levels than environment
environment can temporarily boost or lower IQ but it tends to go back to what your genes are predetermined for in regular conditions
Chase Lopez
Just exterminate shitskins and any mutts they managed to create
Adrian Davis
lol exactly
Andrew Harris
It's called regression, you lying niggers. If you look at some third worlders who were selected for higher IQ by the mere fact that they have the mobility to uproot themselves and move to the USA, their IQs will regress through their children to their racial mean.
Hence, if you get a couple of 120 IQ niggers straight outta Africa and they come here and reproduce, their children are going to average closer to 70 than to 120. Their high IQ, which is an anomaly in their country, is not going to last. It's a fucking demographic time bomb importing third worlders - that's why not even merit-based immigration is good enough. Their children are going to be fucking morons.

What a horrifically dumb post. That means smart drivers are safer from other idiots' stupidity.
This is far more likely to be about lack of appropriate stimulation during childhood (i.e. children spending time at institutions instead of with their parents and grandparents) and things like that.
Daniel Ross
This is from families with kids in the military, so likely leaning slightly more conservative as a whole. But again the data sources for this are not representative of the population as a whole because they didn't run their own data gathering, just got IQ scores from military recruitment.
Jack Brooks
IQ has been falling down in western countries as they are flooded with more and more lethargic low IQ shitskins. Meanwhile in east asia, their IQ has been INCREASING.
Siblings can vary quite a bit as to which genes are expressed.

Jeremiah Allen
"environmental factors are to blame" like what? global warming. The years used in this study correlate to the importation of low IQ people into these countries. Since scientists are always reacting to nothing stories, the decline is probably small which could be explained by the importation of non european peoples and the influence they might have on the native populations.
Asher Diaz
That's nonsense. I've read that it dropped.

its true that IQ is decreasing
the lie is in the claim that high IQ people are breeding more
if you simply look at a map of the world and IQ of countries, and look at the population growth of those countries in the past 100 years, the lowest IQ populations have grown massively while the rest have absolutely stagnated. its indisputable that lower IQ populations are increasing a shitload relative to ours, skewing the average downward
its an outright brazen lie, meant to acknowledge the truth half way in an attempt to cover up the rest of the truth and stop the problem from being fixed
psychologists and sociologists, the people in the fields who would conduct this kind of research, are a bunch of perverted kikes, much of the very same people pushing tranny acceptance and drugs on children and the general population. one of if not the biggest influences on the normalization of that shit.
John Gonzalez
its epigenetic factors,
