Dopamine vs. pages: how social media is hijacking our brains 🧠📱

Open a book. Read for five minutes. Put your phone away. That’s the challenge millions of young people set for themselves every evening—and most lose before they even reach page two. Not because they’re lazy. Not because they lack curiosity. But because another force is at play—silent, precisely engineered, and remarkably effective.

On April 14, 2026, France’s National Book Center (CNL) released the findings of the fifth edition of its study “Young French People and Reading,” conducted by Ipsos BVA. The results confirm what teachers are witnessing daily in their classrooms. And this isn’t just a European story. From high schools in Yaoundé to classrooms in Douala, the same reality is unfolding: screens have taken over—and reading is paying the price.

The numbers that hurt 📉

The core figure from the 2026 CNL study fits on a single line—and it hits hard: young people spend 18 minutes a day reading for pleasure, compared to 3 hours and 1 minute on screens. That’s ten times fewer pages. Ten times more scrolling.

Among 16–19-year-olds, screen time exceeds five hours daily, while reading drops to its lowest level. 56% mainly consume short-form videos, and social media usage reaches 99% in this age group. What’s changed since 2024? Regular reading—daily or several times a week—has declined even further. More than a third of 16–19-year-olds don’t read at all.

Over the past decade, since the first edition of the study in 2016, young people have lost eight minutes of daily reading time. Eight minutes may sound trivial—but they represent books never opened, stories never discovered, and cognitive abilities never developed.

The trap of instant dopamine 🧠

To understand why reading is declining, we need to look at what replaced it.
And neuroscience already has the answer. Short-form video platforms operate like true “dopamine machines.” Every video autoplay, every notification triggers the brain’s reward system. This constant dopamine flow reinforces pleasure-seeking behavior—and can lead to addiction.

Researchers now speak of the “TikTok brain”: heavy consumers of short content struggle increasingly to engage in activities that don’t offer instant gratification. Reading, on the other hand, requires sustained effort before delivering its reward. When a book asks for five minutes of investment—and a video delivers satisfaction every fifteen seconds—the brain makes a choice.

A biological one. Almost automatic.

The 2026 CNL study confirms it: 84% of young people who prefer other activities over reading turn to screens. The effort required by reading simply can’t compete with the instant rewards of digital content.

Even when we read, we don’t really read anymore 😔

Perhaps the most alarming signal in the study is this: even those who still read don’t truly read anymore. Fragmented reading has become the norm. Reading is increasingly broken up:

• 21% of children aged 7–9 say they do something else while reading
• 45% among 13–15-year-olds
• 67% among 16–19-year-olds

These teenagers have a book open—and a phone right next to it. Their attention is split between both, and therefore fully owned by neither. Constant notifications and social media distractions are pulling young people away from deep reading. They fragment attention and weaken the ability to concentrate.

And this is where the vicious cycle locks in: the less we read, the less capable we become of reading. Attention weakens. Comprehension declines. Reading becomes harder—and less enjoyable. Which pushes us back toward screens… that fragment our attention even more. The loop keeps spinning—in the wrong direction.

There’s even a clearly documented breaking point: the moment a child gets their first smartphone—on average at 11 years and 4 months—marks a sharp decline in reading habits. This isn’t a coincidence. It’s a tipping point.

Africa in the same boat—with its own challenges 🌍

The CNL study focuses on French youth. But the phenomenon is global—and Africa is no exception, with its own unique dynamics.

In sub-Saharan Africa, the internet is overwhelmingly mobile-first. The smartphone isn’t a second screen—it’s the first, the only, and often the sole gateway to the digital world. In Yaoundé, Douala, Abidjan, or Lagos, thousands of young people discover TikTok, Instagram Reels, or YouTube Shorts before finishing their first novel—or sometimes without ever holding one.

The same algorithms operate here, driven by the same neurochemical mechanics. And the environment is even more favorable to their expansion. Structural barriers to reading—high book costs, limited access to libraries, and scarce publishing in local languages—have left a vacuum. Digital platforms filled it instantly. Freely. Seamlessly. Infinitely. Not out of malice. But with formidable efficiency.

Which makes the issue even more urgent for our societies: if reading is a cornerstone of critical thinking, focus, and intellectual autonomy, its gradual disappearance is not just a cultural concern. It’s a question about the future.

Reading: an act of resistance ? 💡

Reading isn’t natural. It’s learned, practiced, and chosen. That may be its greatest strength—and its greatest weakness. In a digital ecosystem where every app fights to capture your attention, opening a book has almost become a countercultural act.

CNL president Régine Hatchondo puts it bluntly: reducing excessive screen time means giving freedom back to young people—who are increasingly trapped by algorithms. This isn’t about demonizing screens. They are part of our lives and can be powerful tools for knowledge and connection. But it is about resisting passive consumption—the kind that drains attention without truly nourishing it.

For young people in Africa and Cameroon, the challenge is twofold:
reclaim the joy of reading despite often difficult conditions, and build a conscious, critical relationship with technologies that connect them to the world. It’s not easy. But it’s not impossible.

And what if the first step was simply this: put the phone down—five minutes, one page at a time?
