You’re probably reading this while sitting on a train, or maybe you’re hiding in a bathroom stall at work to get five minutes of peace. Perhaps you have seventeen other tabs open. One is a spreadsheet you’re supposed to be finishing, three are Amazon products you don’t need, and the rest are articles just like this one that you’ve promised yourself you’ll "read later." You won't.
That’s the reality of the modern span of attention.
People love to claim our focus is worse than a goldfish's. You’ve seen that "study" cited everywhere, right? The one claiming humans have an eight-second window of focus while goldfish have nine? It’s a total myth. Microsoft did a study in 2015 that mentioned the decline, but the goldfish comparison was basically marketing fluff with no scientific basis. Goldfish are actually quite attentive. We, on the other hand, are struggling with a complex psychological phenomenon that is being hijacked by billion-dollar algorithms.
What is Span of Attention, Really?
Basically, it’s the amount of time you can spend on a task before your mind starts wandering or you feel the physical itch to check your phone. Psychologists usually break this down into two distinct buckets. First, you have transient attention. This is the short-term response to something shiny or loud—like a notification ping or a car backfiring. Then there’s sustained attention. This is the holy grail. It’s the ability to sit with a difficult book or a complex problem for an hour without looking at the clock.
Honestly, your span of attention isn't a fixed number. It’s not like your height or your shoe size. It's more like a muscle or, better yet, a fuel tank. If you didn’t sleep well, your tank is empty. If you’re stressed about rent, the tank has a leak.
Dr. Gloria Mark, a professor of informatics at the University of California, Irvine, has been tracking this for decades. Her research is actually terrifying. In 2004, her team found that the average attention span on a screen was about 150 seconds. By 2012, it dropped to 75 seconds. In her most recent findings, she notes it has plummeted to roughly 47 seconds. Think about that. We can’t even stay on one digital task for a full minute before the "switch" happens.
The Myth of Multitasking
We need to stop lying to ourselves. You aren't multitasking. You’re "task switching."

When you jump from an email to a Slack message and then back to your report, your brain suffers from what researchers call "switch cost." Every time you toggle, your brain has to reorient itself. It’s like a car engine being turned off and on every thirty seconds. It’s inefficient. It burns more gas. It wears out the parts.
MIT neuroscientist Earl Miller has been very vocal about this. He notes that our brains are simply not wired to multitask. We think we’re being productive, but we’re actually just experiencing a dopamine hit from the "novelty" of a new task. It feels like work, but it’s just busywork. You’re getting a "hit" for every new email you open, but the deep work—the stuff that actually moves the needle in your life—is being left in the dust.
The Physicality of Focus
Focus isn't just in your head. It's in your blood. It’s in your gut.
The prefrontal cortex is the part of the brain responsible for executive function. It’s the "boss" of your brain. It tells you to stay focused on the boring tax forms instead of watching a video of a raccoon eating grapes. But the prefrontal cortex is incredibly energy-intensive. It runs on glucose. When you’re tired or hungry, the boss goes on break, and the primitive parts of your brain—the ones that want instant gratification—take over the controls.
This is why you find yourself scrolling TikTok at 11:00 PM when you know you should be sleeping. Your willpower is a finite resource. By the end of the day, you've used up your "focus budget" on making decisions about what to wear or how to word a sensitive email.
External Hijackers
It’s not just your fault. You are fighting an uphill battle against the most sophisticated persuasion machines ever built.

The "infinite scroll" was designed by Aza Raskin to specifically bypass your natural stopping points. In the old days (like, fifteen years ago), you’d reach the end of a page and have to click "Next." That click was a "unit of effort" that gave your brain a second to ask, "Do I really want to keep doing this?" By removing that pause, tech companies have effectively eliminated our "off" switches.
Can You Actually Rebuild Your Focus?
The good news is that neuroplasticity is real. Your brain can change. It's not a permanent decline into madness.
But it’s hard. It’s really hard.
Most people try "digital detoxes." They go to a cabin for a weekend and stare at trees. That’s great, but it’s like going on a juice fast for three days and then going back to eating pizza for every meal. It doesn't solve the systemic problem. To improve your span of attention, you have to change your relationship with boredom.
Boredom is the gateway to deep thought. When you feel that twitch to grab your phone while waiting for a coffee, that’s the moment of truth. If you grab the phone, you lose. If you sit there and just... exist... for two minutes, you’re training your brain to tolerate the lack of external stimulation. It’s basically "attention weightlifting."
The Role of Flow States
You’ve probably heard of "Flow." It’s that feeling where time disappears and you’re completely immersed in what you’re doing. Mihaly Csikszentmihalyi, the psychologist who coined the term, argued that flow is the secret to happiness.

But you can’t get into flow if your span of attention is fragmented. Flow requires a "ramp-up" period. It usually takes about 15 to 20 minutes of intense focus to enter a flow state. If you get a notification 10 minutes in, you’re kicked back to the start. You never reach the "deep end" of the pool. You’re just splashing around in the shallows for your entire life.
Practical Strategies for the Modern Human
If you want to actually get your brain back, you have to be aggressive. Half-measures don't work.
- Monotasking as a Practice: Set a timer for just 20 minutes. Do one thing. If you feel the urge to check something else, write it down on a piece of paper and stay on the task. The act of writing it down acknowledges the thought without letting it derail you.
- The "Grey" Method: Turn your phone screen to grayscale. It’s amazing how much less addictive Instagram is when everything looks like a 1940s newspaper. The bright red notification bubbles lose their "danger" signal.
- Environmental Cues: Your brain associates places with behaviors. If you work in bed, your brain doesn't know if it’s time to sleep or time to answer emails. Have a specific chair or a specific desk lamp that is ONLY for deep work. When that lamp is on, the phone is in the other room. No exceptions.
- Reading Long-Form Content: Try reading a physical book for 30 minutes a day. Not a Kindle, not an iPad. A physical book. The lack of hyperlinks and back buttons forces your brain to follow a linear narrative, which is the exact opposite of how the internet works.
We also have to talk about sleep. You can do all the productivity hacks you want, but if you’re getting six hours of sleep, your span of attention will be garbage. A study from the University of Pennsylvania showed that people who got six hours of sleep for two weeks straight performed as poorly as people who had stayed awake for two days straight—but the scary part was that they thought they were doing fine. We are terrible judges of our own cognitive decline.
The Future of Attention
There’s a lot of talk about AI and how it might help us manage our focus. Maybe we’ll have AI "gatekeepers" that filter our distractions. But honestly, that’s just another layer of technology between us and reality.
The real solution is likely more analog. It’s about reclaiming the "liminal spaces" in our lives—the commutes, the queues, the quiet mornings—and refusing to fill them with digital noise.
The cost of a shortened span of attention isn't just lower productivity at work. It’s a lower quality of life. If you can’t focus, you can’t listen deeply to your partner. You can’t appreciate a complex piece of music. You can’t follow a difficult political argument. You become a series of reactions rather than a person with intentions.
Take Back Your Brain: The Next Steps
- Audit your notifications tonight. Go into your settings and turn off every single notification that isn't from a real human being. You don't need a "breaking news" alert or a "sale" notification. If it’s important, you’ll find it when you choose to look.
- Practice the "10-minute rule." When you feel the intense urge to check your phone or switch tasks, tell yourself you can do it in 10 minutes. Usually, the "itch" passes within 120 seconds.
- Morning Defense. Do not check your phone for the first 30 minutes of the day. This is the most vulnerable time for your brain. If you start your day in a "reactive" state—responding to other people's needs and headlines—you've already lost the battle for your attention.
- Buy a physical alarm clock. Keep the phone out of the bedroom entirely. This single change is often cited by sleep experts and productivity coaches as the most effective way to reset your cognitive health.
Your attention is the most valuable thing you own. Everyone is trying to buy it, steal it, or manipulate it. Start treating it like the finite, precious resource it actually is.
