Digital Minimalism: Cal Newport's Method, and How to Start

Digital minimalism isn't owning less technology or throwing your phone in a drawer. It's deciding what your phone is for, keeping the few tools that serve the things you care about, and letting the rest go without guilt. The idea comes from Cal Newport's 2019 book, and its central exercise, a 30-day digital declutter, is something you can start this week.

Here's what the philosophy says, how the declutter works, what the research supports, and how to make it stick.

What is digital minimalism?

Cal Newport is a computer science professor at Georgetown University who writes about focus and technology. In Digital Minimalism: Choosing a Focused Life in a Noisy World, published by Portfolio in February 2019, he defines it as "a philosophy of technology use in which you focus your online time on a small number of carefully selected and optimized activities that strongly support things you value, and then happily miss out on everything else" ^[1].

The key word is value. A digital minimalist doesn't ask whether an app has some benefit, since almost every app does. They ask whether it's the best way to support something they care about, and whether it's worth what it costs in time and attention.

The three principles

Newport builds the philosophy on three principles ^[1]:

1. Clutter is costly. Many small apps and services, each harmless alone, add up to a cost in time and attention that can swamp their small benefits.
2. Optimization is important. Choosing a tool is only half the job. How you use it decides how much value you get from it.
3. Intentionality is satisfying. Being deliberate about technology is rewarding in itself, whatever you end up choosing.

Digital minimalism vs a digital detox

A digital detox is a break you come back from, often to the same habits. Digital minimalism uses a break too, but the break isn't the point. The point is what you rebuild afterward.

A detox asks what you can live without for a while. Digital minimalism asks what you actually want back.

The 30-day digital declutter, step by step

Newport tested the method before the book came out: in January 2018, more than 1,600 readers took part in his digital declutter experiment ^[2]. It works in three steps ^[1].

1. Decide what's optional

List the technologies in your life and sort them. By Newport's test, a technology is optional unless setting it aside for a while would harm or significantly disrupt your work or your personal life. For most people, social media, streaming, games and news apps end up optional, while work email, banking and messages from family don't. For the tools you keep, it helps to write down simple rules, such as email only at your desk.

2. Take 30 days off

For a month, set the optional technologies aside. The aim isn't just to endure the absence. Newport asks you to use the time to rediscover what you value and enjoy away from screens: the walk without headphones, the project in the garage, the friend you meant to call.

3. Bring things back on purpose

At the end of the month, start from a blank slate. A technology earns its way back only if it serves something you deeply value, if it's the best way to serve that value, and if you can give it a defined role, with rules for when and how you'll use it ^[1]. "Instagram, because I like it" doesn't pass. "Instagram on Sunday evenings, to see what my sister's family is up to" might.

Where it gets hard

The declutter's rules are rules you set for yourself, which means you can bend them at 11 p.m. after a long day. And the apps you're stepping back from are built to pull you back in. That gap between deciding and doing is where most attempts quietly end.

What the research says

No trial has tested digital minimalism as a whole. But several studies test its parts, and they mostly point the same way.

A month away from one platform. In a large experiment before the 2018 US midterm elections, economists paid Facebook users to deactivate their accounts for four weeks. Compared with a control group, the deactivated group gained about an hour a day, spent more of it with friends and family in person (and watching TV alone), and reported slightly higher well-being. They also knew less about the news. Weeks later they were still using Facebook less than the control group, and about 80% said leaving had been good for them ^[3].

Less, not nothing. In a 2018 experiment, students who limited Facebook, Instagram and Snapchat to about 30 minutes a day in total for three weeks reported less loneliness and depression than students who used them as usual ^[4]. Newport's rules for the tools you bring back work the same way: keep the tool, shrink its role.

Phones and people. In a field experiment at a Vancouver café, 304 people shared a meal with friends or family, their phones either on the table or put away. Those with phones out felt more distracted and enjoyed the meal less. The effect was small, but a similar pattern showed up in a week of surveys about students' everyday social lives ^[5].

Time alone with your thoughts. One of the book's practices is spending time alone, free from input from other minds. It's harder than it sounds. In 11 studies, people typically didn't enjoy spending 6 to 15 minutes alone in a room with nothing to do but think. In one of them, 67% of men and 25% of women gave themselves at least one electric shock during a 15-minute stretch of sitting with their thoughts ^[6].

Checking less often. When 124 adults limited themselves to checking email three times a day for a week, they felt less daily stress than in a week of checking as often as they liked, a modest effect ^[7].

Taken together: less clutter, fewer interruptions and more time with people tend to help, and the effects are real but modest. Expect a calmer month, not a new personality.

Habits that keep it going

The second half of Newport's book is about practices that help a minimalist life stick. Four of them, adapted for an iPhone:

• Spend time alone. Take a walk without your phone, or with it in a bag on airplane mode. Newport's term for the opposite is solitude deprivation: spending close to no time alone with your own thoughts.
• Don't click "like". Newport's advice is blunt: never click like, and stop leaving comments too. Put that energy into a call or a coffee instead.
• Reclaim leisure. His rule is to prioritize demanding activity over passive consumption: making, fixing, playing, learning. If you need ideas, our dopamine menu has fifty.
• Join the attention resistance. Newport calls declaring freedom from your smartphone the most serious step you can take. For some people that means a stripped back setup: here's how to turn your smartphone into a dumb phone.

Whatever rules you choose, they need something that holds them when you're tired. Unrotten can turn "Instagram on Sunday evenings" into a schedule: its Time away from apps goal blocks the apps you choose during the hours you pick, or allows them only within one window each day. Its Fewer app returns goal sets a daily target for how many times you open them, and a daily limit in Unrotten locks them with Apple's Screen Time shield once your time is used up, until the day resets.

Is the Digital Minimalism book worth reading?

If the idea speaks to you, yes. It's a practical book of about 300 pages: the first part makes the case for the philosophy and walks you through the 30-day declutter, and the second covers the practices above, from spending time alone to reclaiming your leisure. If all you want is to spend less time in one app, a firm limit may get you there faster. If your whole relationship with your phone feels out of step with what you value, the book is a good place to start.

Start with what you'd miss

Before you delete anything, take a sheet of paper and write down what you would actually miss if your phone lost every app but the essentials for a month. That list, not the App Store, is your starting point. Everything else is optional, and Newport's bet is that you won't miss most of it.
