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.

Men try to read the most disturbing comments women get online back to them.
If you wouldn't say it to their faces, don't type it.
This isn’t comfortable to talk about.
Trigger warning for discussion of sexual assault and violence.
in 2016, a video by Just Not Sports took two prominent female sportswriters and had regular guys* read the awful abuse they receive online aloud.
Sportswriters Sarah Spain and Julie DiCaro sat by as men read some of the most vile tweets they receive on a daily basis. See how long you can last watching it.
*(Note: The men reading them did not write these comments; they're just being helpful volunteers to prove a point.)
It starts out kind of jokey but eventually devolves into messages like this:
Awful.

These types of messages come in response to one thing: The women were doing their jobs.
Those wishes that DiCaro would die by hockey stick and get raped? Those were the result of her simply reporting on the National Hockey League's most disturbing ordeal: the Patrick Kane rape case, in which one of the league's top players was accused of rape.
DiCaro wasn't writing opinion pieces. She was simply reporting things like what the police said, statements from lawyers, and just general everyday work reporters do. In response, she received a deluge of death threats. Her male colleagues didn't receive nearly the same amount of abuse.
It got to the point where she and her employer thought it best for her to stay home for a day or two for her own physical safety.
The men in the video seemed absolutely shocked that real live human beings would attack someone simply for doing their job.
Not saying it.

Most found themselves speechless or, at very least, struggling to read the words being presented.
It evoked shame and sympathy.

Think this is all just anecdotal? There's evidence to the contrary.
The Guardian did a study to find out how bad this problem really is. They combed through more than 70 million comments that have been posted on their site since 2006 and counted the number of comments that violated their comment policy and were blocked.
The stats were staggering.

So, what can people do about this kind of harassment once they know it exists?
There are no easy answers. But the more people who know this behavior exists, the more people there will be to tell others it's not OK to talk to anyone like that.
