You’re probably scanning this right now. Don't worry, everyone is. Your eyes are likely darting across the screen, looking for a bolded word or a header to grab onto so you can decide if this is worth the next three minutes of your life. It isn’t your fault. Or, well, it’s not just your fault. About fifteen years ago, a guy named Nicholas Carr wrote a book called The Shallows: What the Internet Is Doing to Our Brains, and honestly, it’s only gotten weirder since then.
The book wasn't just a "get off my lawn" rant from a tech-skeptic. It was a Pulitzer Prize finalist for a reason. Carr noticed that he couldn't read books anymore. Not really. He’d sit down with a novel and after two pages, his brain would start itching for a link to click or a tab to refresh. He felt his mind becoming a "skimming machine."
Is it happening to you? Think about the last time you sat through a long movie without checking your phone. Or the last time you read a long-form essay without your thumb twitching toward the edge of the screen.
Neuroplasticity: The Double-Edged Sword
We used to think the adult brain was a static, hard-wired machine. We were wrong. Neuroscience—specifically the work of people like Michael Merzenich—has proven that our brains are incredibly plastic. They adapt. They reroute. If you spend sixteen hours a day processing short, disjointed bursts of information, your brain gets really, really good at... well, processing short, disjointed bursts of information.
But there’s a trade-off.
When you strengthen the neural pathways for "fast skimming," the pathways for "deep linear thinking" start to wither. It’s a biological "use it or lose it" scenario. The Shallows: What the Internet Is Doing to Our Brains argues that we are literally re-engineering our gray matter to be more like a computer circuit—optimized for the rapid movement of data—and less like a human mind capable of contemplation.
The Problem with "The Juggler’s Brain"
Carr uses this great metaphor of a juggler. When we are online, we aren't just reading. We are deciding whether to click a link, wondering if a notification just popped up, and evaluating the layout of a page. This creates a massive "cognitive load."
Our working memory is tiny. It’s like a small thimble. To learn something deeply, we have to pour that thimble into the big bucket of our long-term memory. But the internet is like a firehose. We’re trying to catch the water in the thimble, but the sheer volume and the constant interruptions—those tiny "micro-decisions" about whether to click—knock the thimble over. Nothing gets into the bucket. We end up with a lot of information but zero knowledge.
Why Google Wants Us Distracted
It’s easy to think this is just an accidental byproduct of technology. It’s not. Look at the business models. The faster we zip across the web, the more links we click and the more pages we view, the more data companies like Google and Meta collect. They don't want you sitting on one page for an hour reflecting on a poem. That doesn't help the bottom line.
Efficiency is the god of the internet.
But human thought isn't supposed to be efficient. Creativity is often messy and slow. Deep thinking requires boredom. It requires a lack of stimulation.

The Evolution of the Tools
Marshall McLuhan, the media theorist Carr leans on, once said, "We shape our tools, and thereafter our tools shape us."
- The clock changed how we perceive time, making it something discrete and measurable rather than flow-based.
- The map changed how we perceive space, moving us from physical landmarks to abstract coordinates.
- The internet is changing how we perceive thought itself.
It turns out that the medium isn't just a delivery vehicle for content. The medium is the message. If the medium is a hyperlinked, fragmented, ad-driven chaos, then our thoughts become hyperlinked, fragmented, and chaotic.
What Really Happened to Our Attention Spans?
There’s a common myth that our attention spans are now shorter than a goldfish's. That’s actually a bit of a fake statistic that went viral, but the sentiment feels true. Honestly, the reality is more nuanced. It’s not that we can’t pay attention; it’s that we’ve become addicted to the "novelty bias."
Every time you see a new tweet or a new headline, your brain gets a hit of dopamine. It feels good. It feels like you’re "staying informed." But you’re really just a lab rat hitting a lever.
The Scarcity of Silence
In The Shallows: What the Internet Is Doing to Our Brains, there’s a focus on the loss of "the quiet space." In the past, when you finished a book or an article, you had a moment of silence. You reflected. Now, the "Next" button is already there. The "Infinite Scroll" ensures that the silence never arrives.
Maryanne Wolf, a developmental psychologist and author of Proust and the Squid, has studied how the "reading brain" evolved. We weren't born to read; we had to hijack parts of the brain to do it. And now, we are hijacking those same parts again to scan screens. Wolf worries that we are losing the "deep reading" processes that allow for empathy and critical analysis.
If we can't read deeply, can we think deeply?
Is it Too Late to Go Back?
People love to call this "Luddism." They say we’re just complaining about new tech the same way people complained about the printing press or the radio. Socrates actually hated writing because he thought it would destroy our memory. In a way, he was right—we don't memorize epic poems anymore—but we gained something better: the ability to build on the written ideas of others.
The difference now is the speed and ubiquity of the change. The internet isn't just a tool we use; it’s an environment we live in.
The Price of Connection
We’ve gained a lot, obviously. I can find the answer to any question in three seconds. I can talk to someone in Tokyo for free. But we have to be honest about the cost. The cost is a certain type of consciousness. A calm, focused, singular consciousness that is becoming a luxury.
Reclaiming Your Gray Matter: Actionable Steps
You don't have to throw your MacBook into the ocean. But you do have to be intentional if you want to keep your ability to think for yourself. The Shallows: What the Internet Is Doing to Our Brains is a warning, not a death sentence.
- Practice Monotasking: This sounds stupidly simple, but it’s hard. Pick one thing. Read a physical book for 20 minutes. No phone in the room. If your brain itches, let it itch. That itch is your neural pathways trying to rewire themselves.
- The 24-Hour Digital Sabbath: Pick one day a week. Sunday is usually easiest. Turn the phone off. Put it in a drawer. See how long it takes for the "phantom vibration" in your pocket to stop.
- Change Your Screen to Grayscale: Most of the "pull" of the internet is visual. When you turn your phone to black and white (check your accessibility settings), Instagram looks boring. TikTok looks depressing. Your brain stops seeking the dopamine hit because the "candy" looks like gravel.
- Read Long-Form on Paper: Print out the long articles you actually care about. The lack of hyperlinks and the physical weight of the paper change how your brain processes the text. Research suggests we retain information better when we read it on a physical page rather than a screen.
- Kill the Notifications: Seriously. If it’s not a human being trying to reach you personally, you don't need a buzz in your pocket. Every notification is a "micro-interruption" that resets your focus clock. It takes an average of 23 minutes to get back into "the flow" after an interruption.
The internet is a wonderful servant but a terrible master. We’ve spent the last two decades building a world that demands our distraction. It’s time to start building a personal environment that protects our focus.

Next Steps for Deep Work:
Start by choosing one high-density book this week—something you’ve been meaning to read but felt was "too heavy." Commit to 30 pages a day in a room without a screen. Observe how your focus fluctuates and resist the urge to check your devices until the session is over. This builds "attentional stamina," which is the only real currency in the modern economy.
