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.
people were saying this about millennials as well. in fact, James Flynn (for whom the Flynn effect is named) literally said that teenagers in 2009 were dumber than teenagers 30 years ago. call me when there’s a consensus from neuroscientists about this. for that matter, call me when standardised testing is a useful measure of intelligence
Between no child left behind and watching classes that teach you about things in the real world (homec, interviews, taxes, etc.) disappearing a year before I was supposed to take them in that era? I can understand that by measure of capability as prior generations understand it we are falling behind each generation. That was just when we started losing momentum.
