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 am Gen X and our parents plunked us in front of the TV however there were only 3 channels that often had nothing of interest to kids on. But they also kicked us out of the house all day so we had to find other kids to play with and negotiate with, so got more exercise, had adventures without adults managing every minute of our time. We walked to school by ourselves, no buses picking us up at the door. But the parents didn’t really spend more time with us because they were working… sometimes more than one job and daycare did not exist. Now if you did that as a parent, you would get CPS called on you. Also GenX parents went hard the other way being helicopter parents. I was more of a free range parent so had to find other ones to find kids for my son to do things with like ride bikes to the park or drop off to the movies. There has to be a happy medium.
