It has become fashionable, in recent years, to go on a digital detox. Those who can’t face unplugging their own wifi router and turning off their iPhone themselves can pay other people to restrict their tech access in Umbrian eco-hotels, on monastic retreats, or at Camp Grounded, an adult summer camp in California to help nostalgic holidaymakers “disconnect to reconnect”.

A cheaper alternative is to download the SelfControl or Freedom apps, both of which limit internet access for short periods of time to force serial procrastinators to stop googling cat pictures and get back to work. “That worked so well. I need to use @Freedom more often,” tweeted one happy user. Perhaps the apps’ names reveal how degraded these concepts have become in the digital age – the price of Freedom is $10 – but they also demonstrate a deep unease with how the internet has changed us. In 2011, the UN special rapporteur on freedom of opinion and expression declared that cutting off internet access violates human rights. So, if web browsing is a basic liberty, why do so many feel enslaved by it?

One common fear is that modern technology is killing our attention span. We used to spend hours engrossed in a book and read newspaper articles from top to bottom. Now most of us are forever glued to a computer screen with dozens of open tabs, simultaneously skimming the news, scrolling down Twitter and Facebook feeds and checking our emails. We are so bombarded with new information that we struggle to focus on anything longer than a tweet. Or so the argument goes. “What the net seems to be doing is chipping away my capacity for concentration and contemplation . . . Once I was a scuba diver in the sea of words. Now I zip along the surface like a guy on a jet ski,” wrote Nicholas Carr in “Is Google making us stupid?”, his 2008 essay for the American magazine the Atlantic, a classic of this genre. His answer was, in short, yes (though his limited concentration didn’t stop him writing a New York Times bestseller on the subject).

The neuroscientist Daniel Levitin doesn’t believe the internet is making us stupider, but says it has left us with what he describes as “neural fatigue”. “Our brains are busier than ever before. We’re assaulted with facts, pseudo facts, jibber-jabber and rumour, all posing as information,” he writes in The ­Organised Mind. In 2011, Americans absorbed five times as much information as in 1986, equivalent to 175 newspapers. Our hunter-gatherer brains can’t keep up. “Every status update you read on Facebook, every tweet or text message that you get from a friend, is competing for resources in your brain with more important things like whether to put your savings in stocks or bonds, where you left your passport or how to best reconcile with a close friend.”

One of the most damaging illusions of the internet age is that human beings are effective multitaskers. We are not. When we think we are multitasking, we are actually very quickly shifting our attention from one task to the next, and this is exhausting for our brains. It increases the stress hormone cortisol, which scrambles our ability to think clearly. Multitasking is also addictive. Trying to do too many things at once makes people aggressive, impulsive and less sharp. Levitin cites research which suggests that simply noticing there’s a new email in your in-box while trying to concentrate on a different task reduces your IQ by 10 points.

Levitin also works as a consultant, and his analysis is accompanied by dull prescriptions for combating brain fatigue and becoming more like highly successful people (or HSPs, as he likes to call them): write your to-do list on index cards, buy a hook for your keys, manage your time better, don’t constantly check your emails, keep your house tidy and try to get enough sleep. The monotony of this advice is occasionally broken with a bizarre celeb anecdote: Sting “organises and partitions his time to maximise creative engagement”; Joni Mitchell’s home is a “paradigm of organisational systems”, including a drawer devoted solely to Scotch Tape; most hip-hop artists have “meticulously organised” home studios.

The tips offered are so mundane and sensible that they don’t really need scientific justification – most people at least aspire to be a bit more organised and intuitively understand that any attempt to live-tweet EastEnders while catching up on emails and cooking a cheese soufflé is likely to backfire. In fact, the science often seems much shakier than our intuitions. What does it really mean, for instance, to say that Americans “take in five times more information” than in the 1980s? How do you quantify information, and what counts as taking it in? I can (unfortunately) spend an hour scrolling through news websites and recall enough facts to fill a Post-it note.

Levitin’s belief that our “hunter-gatherer” brains are poorly suited to hi-tech multitasking is complicated, too. I imagine that life for our Palaeolithic forebears mentally could be very taxing. How different is the brainwork required to pick berries and simultaneously keep an eye on an infant while watching for hungry lions, from the kind needed for texting while walking down Oxford Street during rush hour? In other words, are we consuming more information, or just different kinds of information, in different ways – and does the distinction matter? These seem pertinent questions but Levitin doesn’t address them.

In The World Beyond Your Head, Matthew Crawford avoids science and looks instead at the philosophical implications of modern tech culture. He believes we are suffering from a “crisis of attention”. The US – or, indeed, Britain – might be commonly described as an “informational economy” but it is more accurately thought of as an “attentional economy”, because attention is the scarcer, and therefore more valuable, good. It is “attention” that advertisers buy, whether they are purchasing an online ad on a popular website, a billboard on the Underground or a prime television slot. ­Virtually every public space or surface has become marketable, and so we are bombarded with adverts everywhere we look.

Crawford is taken aback by an advertisement that flashes up on a card holder just before he enters his credit-card pin, and the one stuck to the back of his fold-out tray on an aeroplane. In South Korea, bus passengers can be squirted with the smell of Dunkin’ Donuts just as they reach the shop. “In a culture saturated with technology for appropriating our attention, our interior mental lives are laid bare as a resource to be harvested by others,” he writes. To make things worse, modern technology seems to generate in us an ever-greater need for stimulation. We are addicted to our buzzing mobiles, our rapidly filling in-boxes and ­24-hour news. For all that we’ve gained, it can feel like we have lost something, too. “We don’t feel our attention is ours, and we complain about it,” Crawford writes.

Yet his target isn’t simply technology and the way it has facilitated the admen: it is Enlightenment philosophy and classical liberalism. These have bequeathed modern society a misguided sense of the self as something separate and isolated from the material world around us. According to this world-view, we don’t encounter objects directly, but rather through our own mental representations of them: the colour blue does not exist in the world, but is a function of our perception. Intellectual freedom requires dependence on one’s own innate rationality. Autonomy is unencumbered freedom of choice. Modern technology serves this Enlightenment sense of self: ­increasingly, we encounter the world through screens. We scroll down online menus and choose things with the click of a mouse. The problem is, a click is a pretty weak form of agency.

Crawford has a PhD in philosophy and has run a motorcycle repair shop for almost 15 years, ever since he walked out of his job with a Washington think tank after five months. This unusual background has shaped his philosophy. In 2009, he wrote Shop Class as Soulcraft, a treatise celebrating the value of skilled manual labour, which became a bestseller. The World Beyond Your Head picks up this theme.

In his view, we learn and perceive and exist through interacting with the world directly. A practised motorcyclist probably can’t explain the science of why he needs to lean to make a corner, but develops a feel for riding that is learned only through doing. Increasingly, however, modern technology creates a degree of separation between an individual’s actions and his effect on the world. Driving in cruise control isn’t just boring for petrolheads, but is a symptom of a greater social malaise. Our reliance on “frictionless” or “user-friendly” technology, which seeks to anticipate our needs, makes us easier to manipulate by governments or, more usually, by big corporations. At the very extreme are modern slot machines. These are designed to be so easy to use that gamblers spend maximum amounts of money. The odds are determined by computers, so that users can’t rely on their ability to judge probabilities accurately. And they are so ­addictive that some troubled individuals wear dark trousers in anticipation of wetting themselves, unable to peel themselves away from the machine.

Crawford’s writing is dense and is hard work at times, but it can also be elegant and impassioned. His critique of modern culture is broad. He rages against the rise of muzak, against population surveys and the way in which they have created a desire to conform, against our increased aversion to face-to-face confrontation and our nastiness online, at how “political discourse has become a performance art of fake outrage”. His argument can become overblown, but it is thought-provoking. “Could muzak be made opt-in rather than opt-out? Once ­every 20 minutes, somebody in the room would have to deliberately hit a button to restart it, and thereby actively affirm that, ‘Yes! We want some emo in here!’,” he implores in his angry, pacy conclusion.

While Levitin wants to combat brain drain with index cards, and Crawford wants to kill the muzak and promote skilled industry, Michael Corballis’s The Wandering Mind is instead a celebration of our brains’ capacity for straying off-task. Modern technology may have provoked new anxieties about our short attention span, but it has also offered insight into what the brain is doing when we zone out or fall asleep or wander off-task.

Imaging techniques show that when we appear to switch off, the brain, far from slowing down, stays pretty busy. Blood flow to the idle brain is only 5 to 10 per cent lower, and larger parts of the brain are active. It is thanks to our capacity for mind-wandering that we are able to form memories, plan for the future, empathise with others, create new things and tell stories.

Corballis’s book is, perhaps fittingly, a meandering exploration of why it is not always good to be on-task or “mindful” – although, if it has one overall message, it is this: “nature designed us to dream, to escape the channels that confine us”. This is a comforting reminder that, whatever the impact of technology on our brains, it is not predetermined. Our frustratingly large capacity for distraction is also an innate source of freedom.

Meet Scotland's 300-year-old snow patch, the Sphinx

Snow patch watchers expect it to melt away by the weekend. 

This weekend, Scotland's most resilient snow patch, dubbed Sphinx, is expected to melt away. The news has been met with a surprising outpouring of emotion and nationwide coverage. Even The Financial Times covered the story with the headline "The end is nigh for Britain's last snow". The story has also gone international, featuring in radio reports as far away as New Zealand.

So what is it about Sphinx that has captured the public’s imagination?  Some have suggested it could be symbolic. The Sphinx represents how we all feel, helpless and doomed to a fate determined by leaders like Donald Trump and Kim Jong Un. 

Regular contributors to the Facebook page “Snow Patches in Scotland”  have their own, more prosaic theories. One tells me that the British are “generally a bit obsessed with weather and climate”, while another says snow-patches are "more interesting than anything Trump/May/Boris or Vladimir have to say”.

Those more interested in patches of snow than the existential consequences of international relations could be dismissed as having seriously skewed priorities, but there's more to the story of Sphinx than lies on the surface. 

For a start it's thought to be 300 years old, covering a small square of the Cairngorms for centuries with just six brief interruptions. Last time the Sphinx disappeared was 11 years ago. Though it may melt away this weekend, it is expected to be back by winter. 

Iain Cameron, the man who set up the Facebook page "Snow Patches in Scotland" and someone who has recorded and measured snow patches since he was a young boy, says that Sphinx has shrunk to the size of a large dinner table and he expects it will have melted entirely by this Saturday.

It came close to disappearing in 2011 as well, he adds. In October of that year, Sphinx at around its current size and only a heavy snowstorm revived it.

"They tend to keep the same shape and form every year," Cameron tells me. "It might sound weird to say, but it’s like seeing an elderly relative or an old friend. You’re slightly disappointed if it’s not in as good a condition."

But why has Sphinx survived for so long? The patch of land that Sphinx lies above faces towards the North East, meaning it is sheltered from the elements by large natural formations called Corries and avoids the bulk of what sunlight northern Scotland has to offer. 

It also sits on a bid of soil rather than boulder-fields, unlike the snow patches on Britain's highest mountain Ben Nevis. Boulder-fields allow air through them, but the soil does not, meaning the Sphinx melts only from the top.

Cameron is hesistant to attribute the increased rate of Sphinx's melting to climate change. He says meterologists can decide the causes based on the data which he and his fellow anoraks (as he calls them) collect. 

That data shows that over the past 11 years since Sphinx last melted it has changed size each year, not following any discernable pattern. “There is no rhyme or reason because of the vagaries of the Scottish climate," says Cameron.

One thing that has changed is Sphinx's title is no longer quite so secure. There is another snow patch in near Ben Nevis vying for the position of the last in Scotland. Cameron says that it is 50:50 as to which one will go first.
