Gen Z has managed something no modern generation pulled off before. After more than a century of steady academic gains, test scores finally went the other direction. For the first time ever, a new generation is officially dumber than the previous one.

The data comes from neuroscientist Jared Cooney Horvath, who has spent years reviewing standardized testing results across age groups. “They’re the first generation in modern history to score lower on standardized academic tests than the one before it,” Horvath told the New York Post. The declines cut across attention, memory, literacy, numeracy, executive function, and general IQ. That’s not just one weak spot. That’s the whole darn dashboard blinking at once.

Horvath took the same message to Capitol Hill during a 2026 Senate hearing on screen time and children. His framing skipped the generational dunking and focused on exposure. “More than half of the time a teenager is awake, half of it is spent staring at a screen,” he told lawmakers. Human learning, he argued, depends on sustained attention and interaction with other people. Endless feeds and condensed content don’t offer either.

    Perhaps could compare similar data from countries that aren't destroying their school systems as effectively.

    "The same decline appears outside the United States. Horvath told senators that across roughly 80 countries, academic performance drops after digital technology becomes widely embedded in classrooms. The timing alone raises serious questions about how learning environments affect cognitive development."

    Doesn't say which 80 but 80 should be a broad swath

    I was one of the last classes to graduate before everyone got school-issued laptops or tablets, back in 2015.

    I'm kinda glad I didn't go to school or grow up doing everything on a computer. The retention and repetition just isn't there with me, or most others it seems. Like those typing courses in computer class that we did in elementary; I still type everything using my index fingers and almost nothing else.

    But another part of me wishes I was more computer literate. All I really know how to do is plug stuff in and sign into my profile.

    Whether it is true or not, i love how the article reflexively blames Gen Z. Like, did they invent Tiktok and brainrot? Did they ruin the school system? Did they put microplastics in the food and water?

    Boomers invented Participation Trophies and then blamed Millennials for receiving them. I was a Millennial that would rather have failed then get one and the school system hated me for that

    At the end of middle school, I got a participation trophy for the state science fair, which was a mandatory requirement for graduating 8th grade. It was the only "award" I got at the graduation superlatives assembly.

    The kicker? I actually got an exception for the science fair because I missed 6 weeks of school while almost dying from MRSA pneumonia. This is my millennial villain origin story.

    I'm not sure why this article frames this outcome as the fault of Gen Z. It's not their fault their parents gave them iPads instead of spending time with them, nor for the chronically underfunded educational system.

    Ironic. The article does not frame the outcome as the fault of Gen Z. It in fact goes to great lengths to point out that the fault almost certainly lies with how they were educated, and the parenting environment they were raised in.

    I'll highlight the framed factors for you and where the blame gets pointed.

    Horvath took the same message to Capitol Hill during a 2026 Senate hearing on screen time and children. His framing skipped the generational dunking and focused on exposure. “More than half of the time a teenager is awake, half of it is spent staring at a screen,” he told lawmakers. Human learning, he argued, depends on sustained attention and interaction with other people. Endless feeds and condensed content don’t offer either.

    Schools leaned hard into technology during the same window. Educational software replaced textbooks, long readings, and extended problem-solving. After class, students returned to phones, tablets, and laptops, bouncing between social feeds and bite-sized explanations of material they never sat with for very long.

    “I’m not anti-tech. I’m pro-rigor,” Horvath told the Post. Rigor, in his view, comes from friction. Reading full texts. Working through confusion. Spending time with material that doesn’t immediately reward you. Take that friction away, and cognitive skills dull. Brains adapt to the environment they’re given, and this one prizes speed over staying power.

    The same decline appears outside the United States. Horvath told senators that across roughly 80 countries, academic performance drops after digital technology becomes widely embedded in classrooms. The timing alone raises serious questions about how learning environments affect cognitive development.

    This conversation feels uncomfortable because it doesn’t offer villains or easy fixes. Horvath summed it up bluntly during his testimony. “A sad fact our generation has to face is this: Our kids are less cognitively capable than we were at their age.” His recommendation focused on restraint, dialing back screens in schools, and restoring depth before the next generation is doomed. 

    Most frustrating for me is not just that many people read this article and take away an emotive framing that is completely counter to the text of the article, but that many people on Lemmy that read this article will just memory-hole it and continue to complain about phone bans in school, and the under-16 social media bans going on around the world that are very likely to have significant positive benefits for children's learning and go some ways to resolving the problem.

    Bans and laws like that might have good intentions, but realistically enforcement is either impossible, or the perfect tracking tool on a country or world wide scale...

    Like discord requiring government IDs and face scans; Do you really trust companies & governments to do the right thing, or should we just learn to maybe socialize with our children more?

    I understand your complaints entirely; something really should be done. I just hate that it takes government interference with crappy bans, instead of empowering parents with resources (not working 50+ hours a week to survive) and knowledge (hey maybe 14 hours of screentime isn't very pro-social).

    Sidenote: that part about speed over staying power, I felt that myself. At least within the US, everything is always GOGOGO and cramming over real learning. Probably something with the time is money thing, but school and a lot of college felt like memorization over problem solving or skill building.

    It doesn't have to be perfectly enforced to have a significant positive impact though. Just the signal-effect to parents is enormous. If social media is banned for kinds under 15 (or 16, or whatever), it becomes orders of magnitude easier for parents with 10-year olds to not get the their own smartphone, tablet, etc. It becomes a lot easier to not cave to pressure of disabling parental controls on the same units.

    Basically, the only way a 7-12 year old is getting addicted to a smartphone is if their parents supply one and don't lock it down. When they do that, it's likely due to external pressure of the type "all the other kids have it", and they don't want their kid to be the socially awkward one that's left out. These kind of laws make it easier for parents to collectively agree to hold off on smartphones and social media.

    people were saying this about millennials as well. in fact, James Flynn (for whom the Flynn effect is named) literally said that teenagers in 2009 were dumber than teenagers 30 years ago. call me when there's a consensus from neuroscientists about this. for that matter, call me when standardised testing is a useful measure of intelligence

    Between no child left behind and watching classes that teach you about things in the real world (homec, interviews, taxes, etc.) disappearing a year before I was supposed to take them in that era? I can understand that by measure of capability as prior generations understand it we are falling behind each generation. That was just when we started losing momentum.

    This is directly tied to the No Child Left Behind Act passing 25 years ago. It's been a coordinated effort to dumb down the populace and make them less informed

    Gen Z has a lot of shit stacked against them. I'm glad the article doesn't go "blaming" Gen Z for "being dumber", but instead is focusing on the fact it's a parenting failure. COVID era learning difficulties, constantly being bombarded with tech designed to suck out their soul, AI being everywhere for their college age life, etc.

    As a Millennial, I've seen the blame game. I only hope we come out of this spiral as a society.

    As a millenial who went through the shite by the media about how much of a snowflake we are by getting offended with everything, frivolous for ordering avocado toasts for breakfasts, and clueless and unequipped when it comes to working, I ask: "who raised us?" I remember the parents' moral panic on videogames and cartoons in the 1990s and 2000s. Many kids of my generation weren't let out because the boomer and Gen X parents were made afraid by the constant news cycle of serial killers and high crime rate. And they wonder why we're so sheltered? Now, the media run by older generations are taking potshots at Gen Z claiming they are dumber. Even if that is the case, who are the ones who raised Gen Z to be constantly glued to the phone screen and watching brain rotting contents that led to lower IQ?

    The next time the media complains such and such generation is behaving a certain way or being dumb, even if scientific study says so, ask yourself, who are raising these kids?

    sigh. every generation has this article. and even if it was true the failure would still be at the previous generations, because kids can't be blamed for the school system we decide for them or a society thats so anti family that parents barely have time to give attention to their kids. 

    don't worry gen z: they told the same stuff about us etc. blame generations so we don't see that the real unfairness always was and still is the distribution of wealth.

    Every generation literally doesn't is the point? I do think the framing is bad, but the generational decrease, as a cohort, in attention spans, technical literacy, and skills competency has been a major worry for over a decade now. Computer science educators were sounding the alarm on this in the mid and late teens, for example.

    The point has some validity - the presence of an easy solution allows us to avoid internalizing our lessons.

    The same was said about my generation (Millenials) because we were allowed to use a calculator. And quite frankly, it’s true - I am less capable of mental calculation than my boomer parents. Now that I have kids I have forced myself to do more in my head or on paper to set an example, and I have improved.

    It’s not that their neurons are inferior or that they cannot learn. It’s that it isn’t worth bothering to remember facts or formulae when every little bit of information is a click away.

    and darkness...

    The dumbing down of American is most evident in the slow decay of substantive content in the enormously influential media, the 30 second sound bites (now down to 10 seconds or less), lowest common denominator programming, credulous presentations on pseudoscience and superstition, but especially a kind of celebration of ignorance”

    I might be wrong but I think this might be more of a failing of the US education system than an across the board decline world wide. Although I do think millenials but much more so Gen Z and Alpha are adversly affected by social media than the generations before by tv.

    I wonder if just a larger percentage of Gen Z thinks standardized testing is bullshit and don't even try. I mean, don't get me wrong, I strongly believe the internet has been a greater evil than benefit to the world, and also believe cell phones have done serious damage to attention spans and focus. That is to say, I'm firmly at the "get off my lawn you damn kids" stage of life. But at the same time I admire so much of the younger generations that don't buy into the "work hard and it pays off" bullshit that I was raised with.
