(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

Iq is 80 % genetic. If iq is falling its absolutely because stupid people are having more kids.

This. Society is dysgenic.

Obvious answers: 1) Social Media >> normies discover interwebz. 2) They won't be allowed to consider race as a factor. > have to discount anything that show non-whites in bad light.

>Evolution is Tru- Who the fuck ever told you that evolution is about getting smarter/"better"? Evolving is about adapting, if you are not using that brain power, you will evolve into something less smarter, its use it or lose it.

it might be the estrogen in the water i've noticed that trannes seem dumb even the ones with college degrees

IQ has to be selected for. Do you see any women (or men, for that matter) choosing their mates for their intelligence?
Yeah. Didn't think so.
Elijah Morales
It's literally a function of mass migration. If you have a population with an average IQ of 105 and import a bunch of people with IQs averaging 80 over decades, you're going to see a similar decline over time. Mongrelization stabilizes the IQ decrease somewhere in the middle but definitely lower. The only thing that raises IQ is eugenics, either natural or artificial, that prevents the stupid from breeding.
Lucas Young
You don't see it because you're not looking for it. IQ is correlated with life success and men who fail at life typically don't get a lot of chances to reproduce. You're probably noticing that AUTISTIC people also don't get a lot of chances to reproduce, and that's not because women don't select for intelligence, it's that the autists make no effort to make themselves attractive to women and thus are expected to make no effort to be good fathers and husbands.

>How can we fix IQ? IQ is fine and, pretty much always will be fine
it only appears to be decreasing because the demographics are changing (as these nations get browner, the people generally get dumber).
that doesn't mean guys like us and ours are actually loosing these mysterious IQ points too. relax.

reinvest in education instead of siphoning that money out to the MIC or old kike boomers tax breaks
Education/schooling does NOTHING to raise IQ. This has been proven repeatedly. Only eugenics can raise the IQ of a population, and nothing can raise the IQ of a person beyond the maximum expected should they have adequate nutrition and sleep.

>Whites go from 90% to 56% of the population >Average IQ for total population drops Oy Vey, I dunno
Between 10 and 18 I was reading maybe over 1000 books. International and national literature. No internet back then, and more important, no social media. School was damn hard, and without relations the difference was made there - winners and losers.
I could connect with older people as a teen, 40 years olds, 80 years olds no problem. Now, teens are just freakishly idiotic, even when in groups they will not spend much time together but always chatting with someone online. School is a disaster, kids are semi-literate morons.
