Be honest with yourself for a moment. How many times have you picked up your phone today without a reason? You had no call to make and no message to send. Your thumb simply knew the way, and twenty minutes later you were somewhere you never meant to be, feeling a little emptier than when you started.
That feeling is not a character flaw, and it is not a lack of discipline. According to Dr. Sahar Yousef, a cognitive neuroscientist at the University of California, Berkeley, it is the predictable result of a fight that was never fair.
Dr. Yousef, founder of the Becoming Superhuman Lab, recently appeared on Steven Bartlett's The Diary of a CEOpodcast. Over more than two hours she laid out a message that deserves to lead conversations well beyond the podcast world. Your attention is being harvested, and you can take it back.
The attention trap is built on purpose
Her central claim is blunt. Technology platforms, she argues, are deliberately engineered, with help from behavioural scientists, to maximise engagement by exploiting the survival wiring of your brain. The goal is not to help you be productive or well. The goal is to keep you looking.
This is her argument, not a settled legal finding, but it fits what many former industry insiders and researchers have said publicly for years. The business model of most free platforms is advertising, and advertising pays for your time. Every notification, infinite scroll and autoplay countdown exists because it works.
Now consider what that means here at home. According to DataReportal's Digital 2026: Ghana report, 26.3 million Ghanaians were using the internet at the end of 2025, a penetration rate of 74.6 percent. The same report counted 8.59 million social media user identities in October 2025, about 24.4 percent of the population. DataReportal itself warns that these identities may not equal unique individuals. NapoleonCat's platform data put Facebook alone at roughly 10.9 to 11.2 million users in Ghana across mid-2026, with people aged 25 to 34 as the largest group.
That is a young, connected, ambitious population, exactly the people who should be building businesses, writing code, studying and creating. It is also the audience these platforms fight hardest to keep.
The real cost of one "quick check"
Most of us believe a glance at WhatsApp costs us ten seconds. The research says otherwise.
The most quoted work here comes from Professor Gloria Mark of the University of California, Irvine. Her workplace studies found that people switched between activities about every three minutes and five seconds on average. Interrupted work was resumed, on average, after 23 minutes and 15 seconds, according to a Gallup interview with Mark. The peer-reviewed 2005 conference paper by Mark and colleagues reports a slightly different figure of 25 minutes and 26 seconds.
A fair reading needs two cautions. First, that return time includes other work people did in between, so it is not 23 minutes of staring helplessly. Second, it comes from specific workplaces and should not be treated as a universal law. The sound conclusion is narrower and still serious. After an interruption, recovery takes tens of minutes, not seconds, and constant interruption makes deep thinking very hard.
Mark's more recent data adds a sobering trend. The average time people spend on a single screen before switching has fallen from about 2.5 minutes in 2004 to about 47 seconds in her latest measurements. Our attention is not just strained. Over two decades it has been chopped into smaller and smaller pieces.
The myth of multitasking
Dr. Yousef is direct on this point. Multitasking, she says, is a myth. What we call multitasking is rapid task-switching, and each switch leaves what she calls "attentional baggage," a mental residue that drains energy and slows everything down. In the episode she says it can make people up to 60 percent slower than doing one thing at a time. I could not find that exact percentage in an independent source, so treat it as her claim. The wider principle that switching carries a real cost is well supported by the interruption research above.
If you have ever replied to a message mid-assignment and then spent the next half hour wondering where your momentum went, you have felt it.
The grayscale hack: small switch, real effect
The most practical idea in the episode is also the simplest. Turn your phone's screen to black and white.
It sounds like a gimmick, but it has been tested. A 2024 study in the journal Mobile Media & Communication, with 84 participants, found that one week of grayscale cut daily screen time by 20 minutes. Participants also reported more perceived control over their phone use, less perceived overuse and less stress.
Here is the honest part. The same study found that the number of times people unlocked their phones did not change, which suggests our checking habits run deep. It also found no effect on productivity or sleep. Earlier studies cited in that paper found reductions ranging from 22 minutes a day among 133 participants to 50 minutes a day among 112 participants.
Twenty minutes a day is about two hours and twenty minutes a week, which matches Dr. Yousef's point that the hack can hand back hours every week. It is not a cure, but it costs nothing and takes thirty seconds. On Android it sits under Accessibility settings. On an iPhone it sits under Accessibility, then Display and Text Size, then Color Filters.
The Focus Sprint: stop writing wishes, start scheduling work
Yousef's productivity method is the Focus Sprint. You break a large goal into small, specific tasks, then give each task a strict block of time. She says this engages the brain's anticipatory networks and can double output. The exact doubling figure is her claim, but the logic is easy to test. A vague goal like "work on my project" gives you nothing to start. A task like "write the first 500 words of chapter two in 25 minutes" gives you a finish line.
She also separates your most important tasks from your least important ones, which she calls MITs versus LITs. The point is to protect your best hours for the work that matters and stop letting small tasks eat the day.
Boredom is not the enemy
This is the idea I find most countercultural. We now treat every quiet moment as a problem to be fixed with a screen. At a bus stop, in a queue, in the bath, the phone comes out.
Dr. Yousef argues the opposite. A wandering mind is not wasted. In her telling, it is the mechanism that activates the brain's problem-solving networks and produces some of our best creative insights. Neuroscientists have long linked mind-wandering with the brain's default mode network, though the science here is still developing and no one should promise that boredom will make you a genius.
As a writer, I will say what I know from experience. My best lines have never arrived while I was scrolling. They arrive when I am walking, waiting, or doing something with my hands. We are starving our minds of the empty space where ideas form.
What this means for us
Ghana's digital moment is exciting. Young people here are building brands, learning skills online, selling products and reaching audiences abroad. I know this personally, because my own columns reach readers in the UK, the USA, Canada and Germany. The internet is not the enemy. Unexamined use of it is.
So here is a simple plan you can start this week:
- Switch your phone to grayscale for seven days and watch what happens.
- Pick one important task tomorrow and give it a fixed block of time with notifications silenced.
- Stop reaching for your phone in every idle moment. Let yourself be bored for five minutes.
- Treat attention as the scarce resource it is. Money you can earn again. The hours of focus you lose today are gone.
Dr. Yousef's message is not that technology is evil or that you should throw your phone into a river. It is that you are in a contest against systems designed by very clever people to keep you hooked, and you deserve to know the rules. The good news is that small, deliberate changes can shift the balance.
Your attention is the most valuable thing you own. Guard it like you mean it.
