Your Attention Span Has Collapsed to 47 Seconds – Here’s How to Train Your Brain to Win it Back

In 1971, economist and psychologist Herbert A. Simon warned that a ‘wealth of information creates a poverty of attention’, laying the foundations for what we now call attention economics. Writing about the scarcity of attention in an ‘information-rich world’, Simon warned that advertising and information systems would be designed to compete for attention – overloading us with information rather than filtering out what’s irrelevant.

More than 50 years later, that warning feels more relevant than ever. In the UK, adults now spend over seven hours a day on screens and move between six or seven different social platforms each month. Whether it’s short-form video on TikTok – where 34 million videos are posted daily (around 16,000 per minute) – or doomscrolling on X, home to 500 million new posts (roughly 5,800 per second), our attention is being constantly monetised – and it’s our brain’s reward system that’s paying the price.

In January, a National Geographic report confirmed the scale of the issue: our ‘focalised attention’ has cratered. Early 2000s research found we could stay on-task for around 2.5 minutes. Today, that figure has dropped to roughly 47 seconds.

So, time to lock in.

The idea that the brain can be ‘trained’ like a muscle has long been popular, thanks to the concept of neuroplasticity – the brain’s ability to reorganise itself in response to learning, experience or injury. But when it comes to attention span, the comparison isn’t quite that simple.

‘Strictly speaking, attention span doesn’t shrink like a muscle wasting away. What changes is the stability and allocation of attention,’ explains cognitive strategist Natalie Mackenzie. ‘Sustained attention relies on prefrontal and parietal networks, working memory, and the brain’s ability to suppress irrelevant stimuli. When we repeatedly interrupt ourselves – or allow our environment to interrupt us – the brain becomes more practised at reorienting than sustaining.’

Notifications, messages, meetings and constant digital input mean our brains are now conditioned to switch tasks rapidly. Over time, ‘the brain’s filtering system starts working less efficiently,’ says Mackenzie. ‘We’re training it to expect change, stimulation and interruption. The instructions we’re giving our attentional systems are very different from their original design.’

Put simply: what you practise, you get better at. ‘The more we do something, the more neural pathways strengthen and become automated,’ she adds. ‘That applies just as much to poor attention habits.’

The upside? That pattern can be reversed.

Attention-training expert and Nuroe CEO Hoa Ly has built this principle into his work. ‘The same mechanisms that reinforce distraction can also reinforce focus,’ he says. ‘Even 15 minutes of targeted training a few times a week can begin strengthening the neural systems that support focus.’

Dopamine – often labelled the brain’s ‘feel-good’ chemical – plays a central role in attention. But not in the way most people think.

‘Dopamine isn’t just about pleasure. It’s about reward prediction – the brain constantly anticipating that something interesting might be next,’ says Mackenzie. ‘That unpredictability is exactly what makes digital platforms so compelling.’

This drives task-switching: the unconscious shifting of attention that fragments focus. One notification can derail your workflow, pulling you into a chain of distractions.

The cost is significant. ‘Task-switching places repeated demands on working memory and executive control,’ Mackenzie explains. ‘The brain has to drop one task, load another, and rebuild context every time.’ Research suggests it can take more than 20 minutes to fully refocus after an interruption.

Even quick checks add up. ‘Brief switches – glancing at a message or notification – carry a reattention cost most people underestimate,’ she says. ‘Across a full day, that cumulative loss is substantial.’

Over time, this becomes habitual. ‘Notifications, infinite scrolling and constant updates train the brain to expect the next reward,’ says Ly. ‘Even when your phone doesn’t buzz, part of your brain is waiting for it to.’

It’s a familiar feeling – that low-level anticipation that keeps your mind on edge.

But because the brain is plastic, these habits aren’t fixed. ‘The circuits that support distraction can be retrained,’ Ly says. ‘And that’s the encouraging part.’

This is an environmental issue as much as it’s about personal discipline.

As author Emily Austen argues in Smarter, we’ve normalised a state of ‘perpetual cognitive interruption’ and mistaken it for productivity. ‘Platforms are designed, with extraordinary precision, to interrupt you,’ she says. ‘Every notification, every scroll, every “quick check” is a feature, not a bug.’

Recognising this as a design problem – not a personal failure – is the first step.

The second is moving beyond willpower. ‘You’re fighting systems built by some of the smartest engineers in the world,’ Austen says. ‘Willpower alone isn’t enough.’

Instead, the solution is environmental redesign.

Disable Non-Essential Notifications

‘Every notification is an interruption request,’ Austen says. Reducing them helps limit the cognitive ‘switching cost’ that drains focus.

Focus on One Task at a Time, Without Interruption, Until Completion

Pair this with your peak energy window – tackling high-value work when your brain is freshest, rather than wasting it on low-stakes admin.

Expect discomfort early on. Austen describes the initial restlessness as a form of withdrawal. But within two to four weeks, the constant urge to check your phone begins to fade. ‘The brain will follow the conditions you create,’ she says.

This works because neuroplasticity cuts both ways. ‘The brain operates on a use-it-or-lose-it principle,’ Mackenzie explains. ‘We’ve strengthened the networks for distraction. Now we need to strengthen the ones for focus.’

The recovery timeline is shorter than you’d think. Research suggests that reducing interruptions can quickly improve sustained attention, with noticeable gains in a matter of weeks. ‘The first fortnight is the hardest,’ says Austen, ‘but by the second month, it starts to feel natural.’

Sleep, however, is the hidden variable.

A lack of it doesn’t just leave you tired – it ‘systematically degrades’ the prefrontal cortex, the area responsible for focus, decision-making and impulse control. In other words, you’re not just fatigued – you’re cognitively impaired.

Layer that onto an already overstimulated environment, and the impact compounds.

It’s also worth recognising that not everyone starts from the same baseline. Stress, burnout, ADHD and poor sleep all compete for the same limited cognitive resources needed to focus. ‘Some brains are operating under significantly greater strain,’ Mackenzie notes.

Which makes one thing clear: this isn’t about willpower – it’s about setup.

Rebuild your environment, and your focus will follow. As Mackenzie puts it: ‘The same mechanism that got you here can get you out.’
