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.
All people exist within and help create culture. It’s difficult to resist culture. As a young millennial, social media was everywhere and rapidly became how you interact with people. Many of us got hooked on it or other aspects of the internet. Hell I was reading cracked on my phone in high school after finishing my work instead of reading the book I brought (and yeah getting in trouble for it). It was normal. When I quit Facebook it came with social costs that weren’t intentionally applied, I just didn’t know about things that were happening because they were posted there.
Gen z is more hooked than any previous generation and at a younger age, just like millennials were. But the content has changed from texting peers to browsing the web to doomscrolling to doomscrolling without even needing to read. They bear some responsibility just as we did, but those of us who formed the culture they live in and built these tools also deserve some responsibility, as do the parents who haven’t been raising them to value education as much as ours did and who’ve been providing them with unlimited access to the devices.
