Your attention span is not what it used to be. The constant draw of notifications, feeds, short videos, and endless updates has created an environment where switching away from what you’re doing is easier than staying with it. And while blaming yourself for having no attention span is tempting, the technology competing for it was deliberately built to keep you glued to the screen.
The issue is not simply that people lack discipline. Digital platforms have learned how to turn distraction into a repeatable behavior, while frequent switching can make sustained attention harder to maintain. The good news is that attention is trainable, and changing your environment can be more effective than relying on willpower alone.
Your Attention Span Really Has Changed
Our attention spans, and our ability to focus, have changed. Gloria Mark, a Chancellor’s Professor of Informatics at the University of California, has spent more than two decades studying how people divide their attention while using digital technology. In their research, Mark and her colleagues found that people spent an average of about 2½ minutes on a screen before switching. In more recent observations, that figure fell to about 47 seconds.
The figure does not mean humans now have a universal 47-second attention span. Mark was measuring how long people stayed on one screen before switching, showing a change in digital attention and switching behavior rather than a limit on how long the brain can concentrate. Her 2023 book, Attention Span, explores the cognitive cost of this constant switching and how modern technology has reshaped our attention.
The commonly cited eight-second attention span is now considered a myth. It is often attributed to a 2015 Microsoft Canada study, but the statistic has been questioned and shouldn’t be treated as an established measure of human attention, according to the BBC. The stronger takeaway is that frequent digital switching can make sustained attention harder.
The Design Is the Problem, Not Just Your Discipline
Doomscrolling is unusually difficult to resist because the feed removes the cues that normally tell us to stop. Infinite scroll eliminates an endpoint, notifications bring you back, and algorithmic feeds keep changing what appears next.
Nir Eyal’s Hooked offers a useful framework for understanding why this works: trigger, action, variable reward, investment. A notification or moment of boredom prompts an effortless scroll, while the uncertainty of what comes next keeps the behavior rewarding enough to repeat. The result is a loop that can eventually feel automatic.
That matters because fighting an engineered loop with willpower alone is a bad strategy. If the environment makes distraction effortless, changing the environment is part of changing the habit.

What Doomscrolling Does to Your Brainpower
The cognitive cost of excessive digital consumption goes beyond having a shorter attention span. An analysis in Neuropsychology Review examined 43 studies and found that people with disordered screen-use behaviors showed lower cognitive performance overall, with attention and focus showing the largest deficit, followed by executive functioning. Executive function includes mental skills such as resisting impulses, staying focused on a goal, and shifting deliberately between tasks.
A more recent review covering 71 studies and 98,299 participants found that greater short-form video use was associated with poorer cognitive performance, with particularly strong associations for attention and inhibitory control. The researchers did not establish that scrolling directly causes these deficits, but the pattern reinforces a point worth taking seriously: a media diet built around rapid, endless stimulation is not cognitively neutral.
So “making us dumber” is deliberately provocative. Doomscrolling isn’t proven to lower your intelligence. But if your everyday media habit repeatedly exercises distraction, impulsive checking, and shallow processing, those are the cognitive habits you’re rehearsing.
Rebuild Your Attention Like a Skill
The answer isn’t another productivity hack. It’s practice doing less at once.
Read a book or long-form article without checking another tab. Take a walk without a podcast. Leave some empty moments genuinely empty. Work on one task with notifications out of reach. These are simple mental performance habits that give your attention repeated practice staying with one thing instead of constantly searching for the next stimulus.
Even small acts of deliberate restraint matter. Saying no to the urge to check your phone creates a pause between impulse and action, while learning how to relax after a stressful day without scrolling gives your mind a different way to decompress. The goal isn’t to eliminate stimulation. It’s to become better at choosing when you engage with it.
If you’re curious about dopamine detox, the useful takeaway isn’t that dopamine itself needs to be “reset.” It’s that deliberately stepping away from constant rewards can help you notice how often you’ve been seeking stimulation automatically.
Attention gets stronger through use, not intention.

A Seven-Day Attention Reset
Don’t start with an elaborate digital detox. Start by creating friction.
- Days 1–2: No social feeds for the first 30–60 minutes after waking. This will help you build a healthy morning routine that sets the tone for the rest of the day.
- Days 3–4: Set a no-scroll evening cutoff and replace the feed with reading, conversation, stretching or nothing.
- Day 5: Do one 30–60-minute single-task work block with your phone physically out of reach. If you need extra structure, simple focus techniques can help turn that block into a repeatable habit.
- Day 6: Take a walk without audio. Notice how often you want to reach for stimulation.
- Day 7: Identify the app that created the strongest urge to check. That’s the one worth dealing with next.
The point isn’t to spend seven days being “good” and then return to normal. Use the week as an experiment to find out which changes make sustained attention easier.
The Uncomfortable Ask: Delete the Worst App
Not the app you spend the most time on. The one you open without thinking. Delete it for 30 days. If you genuinely need it, use the browser version instead, where the extra steps create friction. Don’t replace it with another short-form feed.
There is a bigger reason to question what constant phone use is displacing. Jean Twenge, a psychologist at San Diego State University, reviewed research in a 2019 article in Current Directions in Psychological Science and found that heavier digital-media use was associated with lower psychological well-being. Her review points to displaced activities such as sleep, face-to-face interaction, exercise, and time outdoors as possible explanations.
Then see what happens. If you reinstall it after a month, make the decision consciously rather than automatically. The goal isn’t to prove that technology is bad. It’s to find out what your attention feels like when an algorithm isn’t constantly asking for it.
Take Back Your Attention
Doomscrolling is more than wasted time. Constant novelty, rapid switching, and endless feeds can shape how easily you concentrate, resist distraction, and stay with information that takes longer to process. The answer isn’t perfect discipline, but deliberately giving your attention fewer places to go.
You may not become “dumber” because you scroll, but a mind constantly trained to skim, switch, and seek the next hit isn’t being trained to think deeply either. Reclaiming your attention is one way to change that.
