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.
I barely even used a laptop at all until college, and it took me a solid two years to realize that having a laptop in class was too distracting. I switched exclusively to hand written notes and my GPA went from barely holding onto a 3.0 to nearly straight As. By grad school I was competing for top 5 class rank in a top 10 engineering program. It’s fucking nuts how much of a difference writing shit down by hand made in terms of my ability to retain information on first exposure.
