American IQ Scores Have Rapidly Dropped, Proving the 'Reverse Flynn Effect' (popularmechanics.com) 391

An anonymous reader quotes a report from Popular Mechanics: Americans' IQ scores are trending in a downward direction. In fact, they've been falling for over a decade. According to a press release, in studying intelligence testing data from 2006 to 2018, Northwestern University researchers noticed that test scores in three out of four "cognitive domains" were going down. This is the first time we've seen a consistent negative slope for these testing categories, providing tangible evidence of what is known as the "Reverse Flynn Effect."

In a 1984 study, James Flynn noticed that intelligence test scores had steadily increased since the early 1930s. We call that steady rise the Flynn Effect. Considering that overall intelligence seemed to be increasing faster than could be explained by evolution, the reason increase became a source of debate, with many attributing the change to various environmental factors. But now, it seems that a Reverse Flynn Effect is, well, in effect.

The study, published in the journal Intelligence, used an online, survey-style personality test called the Synthetic Aperture Personality Assessment Project to analyze nearly 400,000 Americans. The researchers recorded responses from 2006 and 2018, in order to examine if and how cognitive ability scores were changing over time within the country. The data showed drops in logic and vocabulary (known as verbal reasoning), visual problem solving and analogies (known as matrix reasoning), and computational and mathematical abilities (known as letter and number series).
Not every domain is going down though, notes the report. "[S]cores in spatial reasoning (known as 3D rotation) followed the opposite pattern, trending upward over the 12-year period."

"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," says Elizabeth Dworak, a research assistant professor at Northwestern University and one of the authors on the study. "We need to do more to dig into it." She adds: "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. It could just be that they're getting worse at taking tests or specifically worse at taking these kinds of tests."

          Do not worry. This is all totally normal. Idiocracy was a good prediction of our society though, not our civilization. All empires devolve into a civil war with challenges to sexual morals, family structure, gender, and creed of one kind or another. It has happened to the Greeks; the Romans, the ancient Egyptians, the Qing, the Mongols, the Assyrians; and it will happen to us.

          I personally suspect it has to do with our conflict driven root of ambition. Life gets comparatively too easy due to too much success, and we start to ear ourselves apart. Our bonds of unity are driven apart by our search for conflict. This is what we define today as outrage culture, cancel culture, race baiting, etc etc. These are just incarnations of our desire to find conflict. We dont have a scary USSR out-competing us in space or trouncing us in Vietnam. So, we are here, at the twilight of our hegemony. The part Idiocracy gets wrong is that the whole world doesnt get stupid. We just fall onto hard times and will struggle while another power accents, to repeat the same fate a few centuries later. This is all, I am sorry to say, very normal. It is how super-hegemonic powers like Rome die.

The ancient world was 3 continents: Africa, Asia, Europe. They conquered all of known Africa, all of mediterranean Asia. We were left with just Europe, in crisis, under siege, and missing parts too, like Iberian Peninsula. We had the choice of either uniting and stopping them, or letting them continue picking off European states one by one. But yeah, daring to resist being slaughtered and forcibly converted, what a show of Christian supremacism and fanaticism.

      Cause that's what the study is - bullshit.

      The values they got are in standard deviations.
      So, mean scores between 2006 and 2018 for 18 to 60-year-olds are something like -0.023, -0.014, -0.007 and -0.019, depending on the kind of test administered, in standard deviations.
      In this case, the standard deviation used was 15 IQ points.
      They measured a decrease between 0.007 and 0.023 of THAT.

      I.e. Their results are showing a decrease of 0.105 to 0.345 IQ points, over a decade.
      Just as a reminder, average IQ is 100. Half the people have IQs ABOVE that.
      And if you believe that a decrease of 0.345 of one single part of that number, OVER A FUCKING DECADE, is in any way relevant... well I guess you're not the part of the above 100 crowd.

      For extra understanding just how much bullshit is in this study...

      Starting in 2006, 35 ability items, that would become part of the International Cognitive Ability Resource (ICAR; Condon and Revelle, 2014, Condon and Revelle, 2016; Dworak, Revelle, Doebler, and Condon, 2021; Revelle, Dworak, and Condon, 2020), were administered.
      These items were used to form a composite cognitive ability score or domain scores for matrix reasoning (11 items), letter and number series (8 items), and verbal reasoning (16 items).
      Starting in 2011 an additional item for letter and number series and 24 three-dimensional rotation items began to be administered, with the original items, to allow for a 60-item composite score. Unlike previous Flynn effect studies, participants were disproportionately female identifying (65.03%) and between the ages of 18 and 90.

      Five years into the study, in 2011, they changed how they measure the thing they measure by adding things they measure to the set of things they measure.
      Scores jumped in that year [els-cdn.com] across the board. And the effect actually lasted for a year or two, then it dived in 2014. By about the same amount it jumped up in 2011.
      Prior to 2011, the trend was basically flat. From 2014 on, scores are actually rising across the board, indicating that the curve is regressing back to that original, flat, mean.

Now, what's important is that they learn to be racist in order to fight racism. And since math, objective facts, and the written word are all racist, well, are these findings surprising?

    It's a flaw in the test/methodology. All these sorts of tests are inherently linked to specific assumed responses, and building the test requires an assumption on the part of the test developers on how intelligence can be expressed. This has always been a flaw with IQ testing and why it really doesn't mean what they want it to mean.

          Intelligence could mean a lot of different things depending on context, and intelligence testing is a largely unsolved problem. You can probably just assume that the issue is with the way the test is configured being out-of-step with how people process information and take the test.

      The human race capabilities have not consequentially changed for thousands or tens of thousands of years. How someone responds to any particular test is heavily dependent on their experience and environment and only a little on their innate learning ability.

        Cute narrative. I have one, too:

        LAUSD has about 500k students (k-12) as of 2023. It also employees over 75k staff (mix of teachers, administrators, etc).

        20 years ago the only difference was the number of students was over 750k.

        As the student population has decreased, so did their testing (which reflects the quality of education).

        We have schools which are empty (or nearly so) while we lost 1/3rd of the population. We're not reducing our costs in anyway to reflect the reduced number of students. We should be downsizing both property and employee costs to reflect the massive decline in student population. Or at least see a bump in education quality (spending more per student).

        When you include all ballot approved bonds and spending, we spend more per student that most public schools in the nation and provide some of the most generous benefits to LAUSD staff. And we're doing this with far greater staff-to-student rations than 20 years ago -- and we're STILL producing weaker and weaker high school graduates.

        https://www.latimes.com/califo... [latimes.com]

        In math, 73% of 11th-graders earned A’s, Bs, and Cs. Tests scores showed only 19% met grade-level standards.
        For eighth-graders, 79% earned A’s, Bs and Cs in math. Test scores showed 23% met grade-level standards.
        In English, 85% of sixth-graders earned A’s, Bs and Cs, while 40% met grade-level standards.
        For seventh-graders, 82% earned A’s, Bs and Cs in English. Test scores showed 43% met standards.

        Apparently the solution to failing our K-12 children is to just cover it up with "good grades".

        In our best category, we're pushing out less than half our students who perform at their grade level every year. And math is embarrassing -- not even 20% performing at grade level.

        Maybe, just maybe, the "nonsense" from parents is justified.

          20 years ago the only difference was the number of students was over 750k.

          Nope. You can't just lump teachers in with all the other staff and expect the metric to be a good measure of educational outcomes. Having more administrators and security staff and network techs and lunch staff and other people who aren't involved in the actual teaching might be necessary to keep the school running (or they might not be), but they aren't teaching your kids.

          So is the mix the same as it was 20 years ago, or, as one might suspect from the lower test scores, does LAUSD have far fewer teachers and far more support staff now?

          I couldn't find data as far back as 20 years ago, but in the 2007 to 2008 school year, LAUSD had 45,473 [wikipedia.org] teachers and 694,288 students, or 15.27 students per teacher, and a total of 83,967 employees, or 8.27 students per staff member. LAUSD now has 24,769 [wikipedia.org] teachers for 565,479 students, or 22.83 students per teacher, and a total of 74,000 employees, or 7.64 students per staff member.

          So even though the student-to-employee ratio is similar — even slightly better now — the student-to-teacher ratio got worse by about 50%. There are way, way more non-teaching staff in LAUSD per student, and only two-thirds as many actual teaching staff per student as there were just fifteen years earlier.

          Teacher-to-student ratio is the primary metric that matters. If education quality in LAUSD is deteriorating, the increased number of students per teacher is likely the main reason why. LAUSD has simply become too big to function efficiently, and as a result, more and more money is being diverted away from education towards non-teacher staffing, resulting in worsening student-to-teacher ratios. Until that problem is fixed — probably by breaking up LAUSD into a few dozen districts and letting each district trim the heck out of its support staff — the system's educational performance is unlikely to improve.

          Maybe, just maybe, the "nonsense" from parents is justified.

          I'm reminded of the comic about all the managers sitting around watching the one person work and saying "why aren't we performing better after all our efficiency drives".

          No the "nonsense" from parents isn't justified. The parents protect under performing children and blame everyone but themselves.
          The "nonsense" from legislators also isn't justified. We used to have experts teaching kids, now we have congressmen dictating how kids are taught, -not only no longer by experts but also the dredges of society.

          Teacher used to a noble profession, it is now a bottom tier choice done by people who often fail to find an alternate career (at least in America).

          The "nonsense" is precisely what is causing the problem in the first place. Thank Christ I live in a country where my wife gets to decide what and how to teach without government intervention, where she was required to have a masters degree in the subject matter, for a school that tells parents they either need to control their kids or they will be booted out. Incidentally our education system well and truly outranks that of the USA on every list except for the "Best Countries Report" compiled by ... US News. I guess they probably have US taught students working there so probably couldn't add up the results correctly.

      A similar thing was seen with Lego improving 3D visualization capabilities. It even worked when girls were encouraged to play with the bricks and their scores rose to match those of the boys.

      For a long time it had been claimed that males simply had different brains that were better at 3D stuff, probably due to historically being the hunters, and that was why women couldn't park a car properly. Turns out it's simply down to boys having more experience in that area.

Diversity is only a strength if its components are actually good. Otherwise, diversity is a weakness overall, as evidenced by this and other IQ studies that factor very controversial things like race and national origin.

    I'm a member of my local astronomy club, and I am amazed at some of the things kids know. I had an 8 year old explain Hawking Radiation, including the fact that is is generated by virtual matter-antimatter pairs coming into existence, and one falling into the black hole, and its partner escaping. An 8 year old. At 8 I'm not sure I knew astronomy was a science. Another time, I showed a little girl, who was not even old enough to speak in sentences, Jupiter's Great Red Spot. She told me it was a hole. I tried to explain it was a storm, but she knew what she meant. She knew it was an anti-cyclone, and finally got this across to me in toddler talk. How she knew that I have no idea, but she knew exactly what she was talking about. Maybe "Babies first astronomy book", or "Planetary science for infants?" Then, I have had adults try to explain the flat Earth to me, so maybe the current generation needs some help, but the next one is doing good.
