The Quiet Ways Technology
Is Changing How We Think
The most significant changes technology makes to human life tend not to be the dramatic ones — the new invention, the disruptive platform, the headline moment. They tend to be the quiet ones: the gradual shifts in how we remember, how we concentrate, how we navigate, how we form opinions. The ones that happen so slowly we don't notice them until they're done.
There is a version of this conversation that gets very anxious very quickly — the screen time panic, the kids and smartphones moral crisis, the generational lament. That version is not entirely wrong, but it tends to generate more heat than light. The more interesting conversation is the specific, evidence-grounded one: what are the cognitive changes that digital technology is producing, what do we know about them, and how should we think about them — with neither panic nor complacency?
The honest answer is that some of what's happening is concerning, some is neutral, some is genuinely positive, and all of it is happening fast enough that the research is still catching up with the reality. What follows is an attempt to lay out the clearest picture currently available — not to alarm, but to inform.
Five shifts in how we think — what the evidence shows
We are outsourcing memory to devices — and our internal memory is changing
The phenomenon psychologists call "cognitive offloading" — using external tools to store information rather than memorising it — is not new. Humans have been writing things down to free up mental space since the invention of writing, and Socrates worried that literacy would damage memory. But the scale and immediacy of digital offloading is new. Research from Columbia University found that people who know information is saved to a computer become less likely to remember it — and remember better where to find it. Our memory is adapting to treat devices as an external hard drive.
What the evidence suggests
This isn't straightforwardly bad — freeing up working memory for higher-order thinking has real value. The concern is that some forms of deep memorisation — the kind that comes from having information genuinely internalised and available for creative recombination — may be harder to develop when the habit is always to look things up rather than to sit with them.
Our reading style has shifted from deep to skimming
Maryanne Wolf, a cognitive neuroscientist at UCLA who has spent decades studying reading and the brain, argues that the way we read online — skimming, scanning, jumping between links, reading in an F-pattern that covers the top and left side of a page before trailing off — is different enough from deep linear reading to constitute a different cognitive mode. And crucially, the brain adapts to the mode it practises most. People who spend most of their reading time online are finding it harder to read long-form text with sustained concentration — not because they lack the capacity, but because the neural circuits for that kind of reading require exercise they're not getting.
What the evidence suggests
The ability to read deeply and linearly — to follow a complex argument across many pages, to sit with difficulty rather than scan for the answer — is a skill that requires practice. Like any skill that isn't practised, it weakens. This has implications for learning, for professional development, and for the kind of thinking that long-form reading makes possible.
Navigation is changing spatial reasoning
Before GPS, getting somewhere new required building a mental map — understanding the relationship between places, developing a spatial sense of a city or landscape. GPS removes this requirement entirely: you follow the arrows, and the relationship between places becomes irrelevant. Research using brain imaging has found that people who use GPS extensively show less activation in the hippocampus — the brain region central to spatial memory and navigation — when navigating than people who navigate from internal maps. The hippocampus is also central to episodic memory more broadly. Whether GPS use affects memory and cognition beyond navigation is an active area of research.
What the evidence suggests
This is probably the least alarming shift on this list — the practical cost of somewhat reduced spatial reasoning is low for most people, and GPS provides genuine, significant benefits. But it's a clear example of how offloading a cognitive task to a device doesn't just affect it — it changes the brain that was doing the task.
Social media is reshaping how we form and hold opinions
This is the most socially significant shift, and the one where the evidence is most contested and most incomplete. What is reasonably well-established: social media platforms expose people to a narrower range of viewpoints than they perceive themselves to be receiving; emotional and socially charged content spreads faster and further than calm, nuanced content; and the public, quantified nature of opinion expression on social platforms creates social pressures that influence what people say and, over time, what they think. The specific magnitude and causal direction of these effects on political polarisation, belief in misinformation, and epistemic confidence is still being actively debated.
What the evidence suggests
The structure of social media — its incentives, its algorithms, its social dynamics — is not neutral in its effects on how people form beliefs. Understanding that structure is the beginning of being able to engage with it deliberately rather than being shaped by it unconsciously.
Our tolerance for boredom and discomfort is decreasing
This is perhaps the subtlest change and may turn out to be the most consequential. Digital technology has made every moment of potential boredom — the wait, the queue, the gap between tasks, the quiet — immediately fillable with content. The result, for many people, is that they have stopped experiencing those gaps at all. Research on mind-wandering suggests this is a real loss: unstructured mental time, the kind that feels like nothing is happening, is where creative connections form, where emotional processing occurs, where the default mode network does its best work. Filling every gap removes the gaps that thinking — real, generative, wandering thinking — needs to happen in.
What the evidence suggests
The capacity to tolerate and even value boredom and unstructured time is trainable — but it requires actually experiencing those states regularly enough for the brain to learn they're safe and productive. People who have optimised every gap away may find this capacity atrophied in ways they haven't fully noticed.
None of these shifts are irreversible. The brain is plastic — it responds to what you do with it, and it can recover capacities that haven't been exercised in a while. The question is whether you're making active choices about what you practise, or whether the defaults of the digital environment are making those choices for you.
Four cognitive habits worth deliberately cultivating
This is not a self-help list. It's a specific response to the specific shifts described above — things you can do that directly exercise the cognitive capacities that the digital environment tends to underuse.
Read something long and hard, regularly
Long-form reading — books, long essays, substantial journalism — exercises the neural circuits for deep, linear, sustained attention. It doesn't need to be daily to have an effect, but it does need to be regular enough to be a genuine cognitive habit rather than an occasional indulgence. The format matters: reading on paper is consistently associated with better retention and deeper processing than reading the same content on screens.
Write to think, not just to communicate
Writing by hand, or writing long-form without an audience, exercises both memory and reasoning in ways that typed communication doesn't quite replicate. Keeping a journal, writing out arguments you're trying to work through, taking notes by hand in meetings — these are not nostalgic habits. They're cognitive tools that produce different and often better thinking than their digital equivalents.
Practise being bored on purpose
Leave some gaps unfilled. Sit on the train without your phone. Wait in a queue without a distraction. Walk without a podcast. The discomfort of the first few minutes passes, and what follows — if you've given your brain time to settle — tends to be more interesting than whatever was in the feed. Boredom is not wasted time. It is, neurologically, some of the most productive time available.
Navigate somewhere new without GPS occasionally
This is the smallest change on the list and probably the easiest. Planning a route before you leave, building a mental map of a new area, finding your way back from somewhere unfamiliar — these are spatial reasoning exercises that are genuinely enjoyable once you stop expecting the phone to do them. And the neighbourhoods you end up knowing are usually more interesting than the optimal route.
The goal of all of this is not to use technology less — it's to use it more deliberately, in a way that preserves the cognitive capacities that the digital environment, by default, tends to undermine. Technology is extraordinarily useful. It has made possible things that were unimaginable a generation ago. The question is not whether to use it but whether to use it on your terms or on terms set by systems that have no particular interest in your cognitive health.
Abel Prasad writes often about the intersection of technology and how we live and work — a subject that touches everything from how businesses communicate to how individuals make decisions in a world that is generating more information, more quickly, than any previous generation has had to navigate. The cognitive shifts described here are not problems with simple solutions. But they're worth naming clearly, thinking about honestly, and responding to with the same deliberateness we'd bring to any other aspect of our lives that matters.
Frequently asked questions
Is technology changing the way our brains work?
Yes — but in more nuanced ways than headlines typically suggest. Research from institutions including Columbia University and UCLA has documented measurable changes in how people memorise information, read text, navigate spaces, and form opinions as a result of digital technology use. These changes reflect the brain's natural plasticity — it adapts to the tasks it performs most frequently. The key distinction is between changes that are neutral or positive trade-offs and those that represent genuine losses of cognitive capacity from underuse.
What is cognitive offloading and is it a problem?
Cognitive offloading refers to the use of external tools — notes, phones, search engines — to store or process information rather than doing so internally. It is not inherently a problem; humans have used external memory aids since writing was invented, and freeing up mental capacity for higher-order thinking has real value. The concern raised by researchers is that heavy reliance on external storage may reduce the kind of deep internalisation that allows ideas to be recombined creatively — since you can only combine what you actually hold in mind.
Does using GPS affect memory and spatial reasoning?
Research using brain imaging has found that people who rely on GPS extensively show reduced activation in the hippocampus — the brain region central to spatial memory and navigation — compared to people who navigate from internal mental maps. The hippocampus is also involved in episodic memory more broadly, though the extent to which GPS use affects general memory function beyond spatial navigation is still being actively researched. The practical implication is modest for most people, but it illustrates a broader principle: offloading a cognitive task to a device changes the brain that was performing that task.
How can I protect my ability to focus and think deeply in a digital world?
The most evidence-supported approaches are: regular long-form reading (books, long essays) to maintain deep attention circuits; writing by hand or long-form to exercise memory and reasoning; deliberately leaving unscheduled mental time rather than filling every gap with content; and occasionally navigating or performing tasks without digital assistance to maintain those cognitive capacities. These are not anti-technology positions — they are deliberate practices that exercise capacities the default digital environment tends to underuse.
