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.


So, I tried looking for any sort for any write-up, journal, or article in which Horvath details his findings or data analysis. I haven’t found anything except articles referencing what he said in front of the Senate. Without that, it’s impossible to tell how he determined causality.
Without completely rejecting his correlation to screen time, here are some changes I noticed between my time as a middle schooler and the past decade that I’ve now worked in public education:
Without an understanding of what Horvath was studying, I can only focus on the contributing factors that I saw. And based on those, we fucking failed those kids. All things considered, I’d say that Gen Z is performing pretty well considering how fucked they were from the start.
