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.
Gen-X here. Don’t fucking talk shit about our kids. Are they dumber or did they score lower on tests that no longer reflect the ways we interact with modern life?
They’re measuring lower across all the classical tests designed to measure intelligence. The skills they test for are all very much still needed in modern life.
The tests for measuring any intelligence, or for measuring the intelligence of the neurotypical prior generations? Just like the IQ was built around white men, even more modern testing is based on existing bias. We don’t even really have a good baseline for what intelligence is, so a metric claiming to measure it comes with a mountain of salt.
Every test no matter how flawed is still fundamentally based on the same general set of skills needed to function as a reasonably intelligent human.
Critical thinking, problem solving, rationalization, stress management, recall, etc.
There’s biases in all of the tests and using them to explicitly claim an exact measure of intelligence is dumb as fuck.
You can explicitly claim if someone’s passing the bare minimum. Cause when you get to the extreme side of failure you are literally getting to the point where your talking about full blown mental and developmental issues. People who need full life long assistance.
The fact there’s any kind of souls regression towards that end of the scale as a trend is terrifying and should be treated as a major problem.
This isn’t oh people are just in the spectrum and the tests aren’t fair. Or there’s racism and stuff build in. Cause that would only show a trend in the related groups and can be legitimately accounted for.
People should not be getting stupider across all demographics. That’s a fundamental failing of humanity. We are actually letting the children down.
University “educator” here. There is a dramatic increase in students who are lacking in critical thinking, especially after COVID. I’m not referring to people who just bomb tests, but a complete lack of motivation/ability to do basic things without someone handholding them through the entire process.
We’re seeing students completely refuse to solve basic equations X = Y + Z for advanced upper div computer science courses, or have trouble setting up a basic C/C++ template with very a detailed Readme guiding people through the whole process. We’re also seeing students zone out and blue screen when being guided through a homework question. (“Here’s the equation, where are the numbers in this question description, what happens if you change XYZ”. This is all being done in bite sized chunks). A lot of people only respond to traditional lecturing in a big hall and cannot/will not respond to any questions/reading materials. In these cases, I believe their standardized testing scores reflect their knowledge level accurately.
This isn’t to say there aren’t good students. If you look at the overall distribution, there’s still a decent amount of good/smart students. It’s just that test results are no longer showing a bell curve these days. Usually, it’s a bell curve overlapped with a large tail that can consist up to 20-30% of a class.
I’m brazilian and I have to say the opposite: smartphones are teaching people how to write, read and think quickly. In university scenarios, people are excited by the possibilities technology have made possible for them. People are willing that the country grow in stature. And that means deep philosophical meaning and so on. Also, Brazil is known for its diversity, so anything that is plus diversity will make brazilian people more willing.
I’ve read most of this comment section and I can’t help but think that americans are lacking the meaning they once had. “Building pipe bombs made us smarter”. ok. “television wasn’t as bad as smartphones”. ok. But the landscape changed and now there is the need for diversity. Time won’t come back and that’s fine, we as world don’t need white predominant thinking to be back. We need something that will push us all forward, and that is not measuring and saying people are dumber and finding other measures to say the same again.
Let’s just pull up everyone. You don’t need to be dumb to wish the best for all. As the article says, friction is good. More social, more friction, more thinking.
