American IQ Scores are Dropping
Chicago,IL...IQ scores have substantially increased from 1932 through the 20th century, with differences ranging from three to five IQ points per decade, according to a phenomenon known as the “Flynn effect.” But a new study from Northwestern University has found evidence of a reverse “Flynn effect” in a large U.S. sample between 2006 and 2018 in every category except one. For the reverse Flynn effect, there were consistent negative slopes for three out of the four cognitive domains.
Ability scores of verbal reasoning (logic, vocabulary), matrix reasoning (visual problem solving, analogies), and letter and number series (computational/mathematical) dropped during the study period, but scores of 3D rotation (spatial reasoning) generally increased from 2011 to 2018, the study found. Composite ability scores (single scores derived from multiple pieces of information) were also lower for more recent samples. The differences in scores were present regardless of age, education or gender.
Despite the decline in scores, corresponding study author Elizabeth Dworak said she doesn’t want people to read these findings and think, “Americans are getting less intelligent.”
“It doesn’t mean their mental ability is lower or higher; it’s just a difference in scores that are favoring older or newer samples,” said Dworak, a research assistant professor of medical social sciences at Northwestern University Feinberg School of Medicine. “It could just be that they’re getting worse at taking tests or specifically worse at taking these kinds of tests.”
The study was published earlier this month in the journal Intelligence.
The scientists used the Synthetic Aperture Personality Assessment (SAPA) Project, a free survey-based online personality test that provides test-takers feedback on 27 temperament traits (e.g. adaptability, impulsivity, anxiety, humor) and their ability scores. Thestudy examined survey responses from 394,378 Americans between 2006 to 2018 to examine if cognitive ability scores changed within the U.S. in those 13 years.
A smaller subset of participants (303,540) was recruited between 2011 and 2018. The 3D rotation data only exists for those who took the survey between 2011 and 2018.
Why the decline in IQ scores?
While the study didn’t examine the reason for the decline in IQ scores, Dworak said there is no shortage of theories in the scientific community, including poor nutrition, worsening health, media exposures and changes to education.
“There’s debate about what’s causing it, but not every domain is going down; one of them is going up,” Dworak said. “If all the scores were going in the same direction, you could make a nice little narrative about it, but that’s not the case. We need to do more to dig into it.”
To that end, Dworak and her colleagues are currently trying to access a dataset that contains 40 years of data to conduct a follow-up study.
A shift in perceived values in society also might have affected scores, Dworak said.
“If you’re thinking about what society cares about and what it’s emphasizing and reinforcing every day, there’s a possibility of that being reflected in performance on an ability test,” Dworak said.
She gave the example that there’s been more emphasis on STEM education in recent decades, but does that mean other areas, like abstract reasoning, are receiving less attention in schools?
Another factor could be due to a decline in motivation, Dworak said. Because the SAPA Project is advertised as a personality survey, individuals seeking out the test may be more engaged with sections related to measuring temperament and less engaged with sections that are seemingly unrelated to personality.
The data for this study and item development of the International Cognitive Ability Resource were partially supported by a grant from the National Science Foundation (SMA-1419324).

Education is less important in many families, with the loss of the importance of learning, brains become stagnant. Education starts at home not school. Studies show infants even learn in the womb. With lower IQ parents, their DNA contributes to a lower IQ.
American corporations own our news media, and have thru grants changed education from learning, and utilizing critical thought to just enjoy, have fun focus on other distractions than information and learning.
This commandeering of our education system is planned to form a more docile consumer driven population, all for their gain.
Another problem is brain nutrition, the American diet is chock full of overly processed food loaded with additives banned in other countries , the adage "you are what you eat" is so true, "brain foods" are real. processed foods lack many trace minerals , which are necessary for optimum brain development and operation.
Eat junk, be junk.

That’s obvious look at the dementia in chief! Can’t remember his own name and can’t even read a teleprompter correctly, can’t ride a bike, trips going up Air Force one stairs, and does whatever his master in china tells him to do. That’s why he is known as Beijing Biden.

The 1 black ass Republican can only talk about libtards and Democrats kissing his ass.
Low enough IQ to vote for Trump?
The best candidate won the 2020 election.
Loser Trump running in 2024 guarantees a Democrat win.

Let's be clear - the guy is doing the hardest job in the country, possibly the world at 80. i can't think of too many other 80-year-olds that could come close to being able to do that job.
Cut him some slack. You've never slipped on a staircase before? And are you 80 with the pressure of being responsible for nuclear weapons?
Or are you some dumb 40-year-old driving a tow truck in Sonoara who didn't finish college?

I can’t even call JB an a-hole. He’s just an idiot. Dr. Jill seems to be pretty clueless, too. Somebody in that fam is street-smart or mafia-tied, though. I guess we’ll find out soon who has the gangsta genes in that family…

Spot on. The wingnut parents in both parties care little about topics other that politicizing their children to think like they do instead of encouraging advanced literacy and math to help their kids think for themselves. Hence we get more right wing dotards and left wing gender confused, race-baiters. Both groups are a laughingstock.

Really? The Democrats weren't breaking into our Capitol to stop our valid election.
trumpterds did.
The GOP House is continuing traitor tactics with their distraction BS dog and pony show.
A person with a decent IQ can see that, Qpubs cannot.

^ How FUKING convenient the libtards forgot when they stormed the capital back in October of 2018 whining and bitching about the Supreme Court nominee. I will never forget! How about the time the Democrats BOMBED the US Senate back in 1983. I haven’t forgotten about that either. You all are quick to point the finger that’s for sure but some of us out there will NEVER FORGET what you all did to this nation!

It's because the illegals flooding our borders are the least educated in the country they're coming from. Democrats like to add to their voting base with dumb people who are easily fed the kool aid !

The guy driving my taxi in Stockton last week was a doctor in Pakistan. I don't think the problem is the immigrants. I think the problem our kids spend more time doing 'active shooter' drills then learning calculus.

Which is why he's a cabbie and not a doctor here.
We need more selective driver's tests (practical and written ) and an exam to vote. 2 digit IQ? No ballot for you.

To the moderators of comments on thepinetree.net,
The political comments on EVERY article on
this site are VERY boring and offensive.
I am wondering WHY youre letting this continue...... ?
....and to the persons posting these comments, geeze give it a break. Really.
Im pretty sure all of you all already know that >>NO-ONE CARES ABOUT YOUR OPINIONS! The only reason you post here is because no one will listen to you in the REAL world.....so youre on here, telling others what to do.
So, pinetree moderators of the comments on here, THESE GUYS ARE COSTING YOU READERS...
I understand that some of these commentors may possibly be nice, respectful and even considerate to other peeps in the real word... however, I also strongly believe that as many as 80% of you would NEVER EVER talk face to faceto someone the way you talk to them on here!!
... why?
Well, probably because
1. its flippin way rude, impolight and super- aggressive, and,
2. because you are a coward. If you talked to others, in person, face to face, the way you talk to them on here, you'd very likely get beat up -or worse!!!
But aside from all that, its just plain boring.
I suggest you go out and work on trying to develop some sort of real-world relationships ....NO-ONE ON HERE WANTS TO HEAR THIS GARBAGE.
Please, just stop.

Betting media consumption is a major contributor. Gone are the days when the public gets 30 minutes of factual television reporting and develops well considered opinion vs having his slanted news choice spoon fed. Along with so many not receiving a quality education that encourages discernment. Concurrently - while we've gotten a handle in the older population on colorectal cancer - those numbers are increasingly in younger adults. Evident is anecdotal at this point but appears less about weight and fitness than it does alcohol consumption.

If one doesn't open one's minds to new ideas, all those little pathways and synapses do not develop fully. No surprise with these findings given how many Americans now believe whatever their news talking heads tell them.
