Gen Z is the first generation less cognitively capable than their parents but Denmark has a solution
"Since the late 1800s, every generation has outperformed their parents."
Gen Z is the first generation less cognitively capable than their parents. Denmark has the solution.
Nearly every parent hopes their child will be better off than they are: smarter, more secure, and more well-adjusted. Many parents see this as a stamp of successful parenting, but something has changed for children growing up today. While younger generations are known for their empathy, their cognitive capabilities seem to be lagging behind those of previous generations for the first time in history.
Dr. Jared Cooney Horvath, a teacher turned cognitive neuroscientist who focuses on human learning, appeared before Congress to discuss concerns about cognitive development in children. In his address to the members of Congress, he says, "A sad fact that our generation has to face is this: our kids are less cognitively capable than we were at their age. Since we've been standardizing and measuring cognitive development since the late 1800s, every generation has outperformed their parents, and that's exactly what we want. We want sharper kids."

Horvath explains that the reason this happens is that each generation has gone to school longer than the previous generation. Gen Z is no exception to the longer duration of time spent in school, but they're the first ones who aren't meeting this normal increase in cognitive development. According to the cognitive neuroscientist, the decline is due to the introduction of screens in the classroom, which started around 2010.
"Across 80 countries, as Jean was just saying, if you look at the data, once countries adopt digital technology widely in schools, performance goes down significantly. To the point where kids who use computers about five hours per day in school for learning purposes will score over two-thirds of a standard deviation less than kids who rarely or never touch tech at school," Horvath reveals.
In most cases, the decline in performance doesn't result in better strategies. The neuroscientist shares that the standardized testing has been adjusted to accommodate lower expectations and shorter attention spans. This is an approach that educators, scientists, and researchers went to Capitol Hill to express wasn't working. But not every country is taking the approach of lowering standards to meet lowered cognitive ability. Denmark went in the opposite direction when it realized their students were slipping behind.
France24 recently interviewed educators in Denmark following their seemingly novel approach to students struggling with cognitive development. Since the beginning of the 2025/2026 school year, Denmark has not only been having students turn in their cellphones, but they've also taken tablets, laptops, and computers out of the classroom. No more digital learning for the majority of the school day. Danes went old school by bringing back physical textbooks, workbooks, and writing assignments. The results have been undeniable. Even the students can't seem to deny the success of the countrywide shift in educational approach.
"I think the biggest issue has been that, because we kind of got rid of the books and started using screens instead, that we've noticed that a lot of the kids have trouble concentrating, so it's pretty easy to swipe with three fingers over to a different screen and have a video game going, for example, in class," Copenhagen English teacher, Islam Dijab tells France24.
Now, instead of computers being part of every lesson, Denmark uses computers very sparingly and with strict supervision. One student says that it has been nice not having screen time at school because she loves to read and write. But it wasn't just the lack of attention span children were developing, they were also developing low self-esteem and poor mental health due to the amount of time spent on devices.

The data showing the negative impact of screens on teens' brains has prompted a nationwide change in Denmark that extends outside of the classroom. Afterschool activities are eliminating or extremely limiting electronic use. There is also a national No Phone Day that encourages everyone to put away their devices for the day, and Imran Rashid, a physician and digital health expert, is petitioning parliament to ban social media use for children under the age of 15. The no phone movement in Denmark is a nationwide effort that hopes to right the ship before another generation feels the effects.

Before you click 'send' on anything else, read this comic. It's important.
Everyone seems to be clicking "send" a bit too early nowadays.
We officially live in a world where internet trigger-happy world leaders can send massive populations into a devolved tail spin with erratic tweets, posts, and subsequent responses. These posts can have far-reaching consequences, and in the haste to respond in kind we've forgotten that we've normalized this kind of attitude.
Boulet is a French comic artist who has been writing about this for 15 years.
Originally he started writing an autobiographical series, but when he realized how accessible it was to his readers, he decided to make it fictional. "So it's mostly 'drawn stand up comedy,'" he explains. "I'm the main character, but in the same way comedians are there own character when they are on stage. The purpose is not really to talk about me but about situations of everyday's life everyone can relate to."
In his words, "The comic (below) was an anecdote about a Facebook mistake, I had basically two choices: Use it as a Facebook status to make my friends laugh or try to dramatize the whole process into an internal crisis to make it a story."

That "internal crisis" is something Boulet is very interested in.
Boulet enjoys using the accessible medium of cartoons as a way to explore complex issues. He loves learning about and studying consciousness and neuroscience. His fans enjoy this.
"There were fun discussions in the comments about how the brain works ... the very idea that we have a parallel process that can interfere, overlap or get in conflict is actually a thing. What I found most intriguing about this story was to literally feel my hand freeze BEFORE I could put an explanation on the WHY it froze."
He also had a great suggestion as to figuring out the motivations behind certain posts. "We should always go on social networks with EEGs on. We would learn a lot."
After what we've seen on social media over the last few years, it's hard to disagree.
