Deep work vs shallow work
Deep work, in Cal Newport’s terms, is focus without distraction on cognitively demanding work that produces rare, valuable results. Shallow work is the logistical work almost anyone could do with minimal training. Both are needed; the ratio is the decision.
68% of people say they don’t have enough uninterrupted focus time during the workday.
— Microsoft Work Trend Index, 2023Where deep work vs shallow work comes from
The distinction is Cal Newport’s. A professor and author, he sketched it on his blog in November 2012, in a post he labelled “Deep Work (v.1).” There, shallow work is “tasks that almost anyone, with a minimum of training, could accomplish,” such as email replies, logistical planning and tinkering with social media. Deep work is “cognitively demanding activities that leverage our training to generate rare and valuable results, and that push our abilities to continually improve.”
The full version is his book Deep Work: Rules for Focused Success in a Distracted World (Grand Central Publishing, January 2016). Its publisher sums up deep work as “the ability to focus without distraction on cognitively demanding tasks” and lists four rules, the last of which is Drain the Shallows.
How deep work and shallow work differ
The line is not between important and unimportant work. It runs between what a task demands and what it produces. Deep work needs sustained, undistracted concentration and produces something hard to replicate: the analysis, the design, the piece of writing, the problem that needs real thought. Shallow work survives interruption and fragments, and produces something almost anyone with a little training could produce.
Two features make the split matter in practice. The first is that shallow work is easier to choose. Newport’s 2012 post says it is attractive because it is easy, which makes us feel productive, and because it is rich in personal interaction, which we enjoy. The second is that deep work is expensive to start. “Deep work is energy intensive,” he writes, which is why he recommends a ritual to move into it rather than expecting to switch over casually.
Put those together and the default is predictable. Left alone, a week fills with the work that is easy to start and pleasant to do, and the work that needs a running start gets whatever is left.
That is why the comparison ends in a ratio rather than a ranking. Shallow work is not waste; some of it is the job. In a 2016 post Newport tells readers to explain the two kinds of work to their boss, “noting, of course, that both are important,” then ask what ratio of deep to shallow work hours the role should run at, and promise to measure and report back. Measuring is possible because a deep session has a clear start and end, so the hours can be counted and the number improved.
Deep work vs shallow work examples
Newport supplies a plain example of shallow work taking over, from his own calendar. In a December 2014 post he describes an unplanned afternoon at his office, meant simply “to get some work done,” that turned into three hours of “fierce busyness”: emails answered without the issues behind them getting resolved, logistics worked out, a half-dozen trips to the printer. Measured against the projects his near-term career rested on, nothing of consequence was accomplished. His conclusion is that the working mind “will always default to the watering hole of shallow busyness if not reined with confidence.”
Newport’s case study of a reader, Tom, shows the ratio conversation working. Tom worked in marketing at a venture-backed start-up where the unspoken rule was to answer email and Slack almost immediately, and his days went to “putting out fires.” He explained deep and shallow work to his boss and asked about her expectations. They settled on a 1.5 to 2 hour block of uninterrupted deep work in the morning and another in the afternoon, with prompt replies outside them. Three months later, his report: “nothing broke.”
At the far end of the scale is Milton Friedman, as Newport retells him from an interview. Friedman split his life between six months a year in Chicago and six in Vermont, and almost all of his writing was done in Vermont or New Hampshire. Newport calls it an extreme version of the bimodal method: deep work gets whole seasons, shallow work gets the rest.
Illustrative scenario, with no real company or figures: an operations lead’s Tuesday holds a pricing model the leadership team needs by Friday, plus a stream of vendor emails, approvals and meeting prep. The model is deep work; it needs an unbroken block and her full attention. The rest is shallow: necessary, and fine in the gaps. Sorted that way, the model gets the morning and the inbox gets the afternoon. Unsorted, the inbox gets both.
Where deep work vs shallow work breaks
Treating shallow work as waste. Newport’s own advice is that both kinds are important, and plenty of shallow work is the job: the approval that unblocks a team, the reply a customer is waiting on. The goal is a deliberate ratio, not zero shallow hours.
Assuming everyone controls their calendar. The boldest routines belong to people with unusual autonomy. Writing about the “monk mode morning,” no meetings, calls, email or internet from waking until noon, Newport notes that not everyone is in a position to run it, and that most of the people who told him about it run their own companies. For everyone else the ratio is negotiated, which is why his advice starts with a conversation with the boss.
Making it only a personal discipline problem. In A World Without Email (2021), Newport argues that the “hyperactive hive mind” workflow that email and messaging tools helped create has become a productivity disaster, and that the fix is clear processes for how tasks are identified, assigned and reviewed. If a team runs on unscheduled messaging, one person’s protected block is fighting the workflow, not just their own habits.
How The Resilience Engine runs it
The Resilience Engine’s Deep Work framework starts where this distinction ends. It names the important work first, then sorts it into what genuinely requires deep, uninterrupted concentration and what can survive in fragments. The deep part gets a block that is, by the book’s rule as the framework page publishes it, unmovable, ninety minutes minimum, scheduled in peak cognitive hours, and protected with the same rigor as a board meeting.
It also names two ways the block fails, and the second is the one calendars hide: the pull to check that comes from inside, after the notifications are already off. A Resilience Engine essay on calendar audits names what the shallow side costs.
“The first is that no block exists. The second is that the block exists and leaks.”
“Focus scheduling without emotional regulation is a calendar fiction.”
“Cal Newport names the resource at stake in Deep Work: the scarce thing is undistracted attention, and shallow work is what quietly drains it.”
| Deep work | Shallow work | |
|---|---|---|
| Newport’s definition | Cognitively demanding work that produces rare, valuable results | Tasks almost anyone could do with a minimum of training |
| Attention it needs | Undistracted, held over a block | Survives interruption and fragments |
| Examples | Research, writing, analysis, a pricing model | Email replies, logistical planning, approvals |
| Why it wins or loses | Energy intensive; needs a ritual to start | Easy, feels productive, rich in interaction |
| How much | A ratio you set deliberately, then measure | The rest of the week, never zero |
| In The Resilience Engine | Unmovable blocks, ninety minutes minimum | Kept out of the block, handled in the gaps |
Questions people ask
- What is the difference between deep work and shallow work?
- Deep work, in Cal Newport’s definition, is cognitively demanding work done without distraction that produces rare, valuable results and improves your skills. Shallow work is the logistical work almost anyone could do with a minimum of training, such as email replies and logistical planning. The first is hard to replicate. The second is easy to replicate, and easy to fill a day with.
- What are examples of shallow work?
- Newport’s own list is email replies, logistical planning and tinkering with social media. Most scheduling, routine approvals and status messages belong there too: work that needs attention but not your full concentration or your particular expertise. In his December 2014 account, an unplanned afternoon went to emails, logistics and printer trips, and nothing of consequence got done.
- What are examples of deep work?
- Research, serious writing, analysis, design and hard problem-solving: work that needs sustained concentration and produces something others could not easily reproduce. Newport describes his reader Tom’s marketing job as centered on cognitively demanding research and writing. Milton Friedman did almost all of his writing in the months he spent in Vermont or New Hampshire, away from Chicago.
- Is shallow work bad?
- No. Newport advises explaining the two kinds of work to your boss “noting, of course, that both are important.” Shallow work keeps a team moving. The problem is shallow work that expands by default until no deep work is left, which is why he recommends agreeing on a ratio of deep to shallow hours and measuring it.
- How do you reduce shallow work?
- Agree on a ratio of deep to shallow hours with your manager, then defend it with fixed blocks. Newport’s reader Tom settled on a 1.5 to 2 hour block each morning and afternoon, answering messages promptly outside them. At team level, Newport’s A World Without Email argues for clear processes for how tasks are assigned and reviewed in place of constant messaging.
- Who came up with deep work and shallow work?
- Cal Newport. He sketched the distinction on his blog in November 2012, in a post labelled “Deep Work (v.1),” and set it out in full in his book Deep Work: Rules for Focused Success in a Distracted World, published by Grand Central Publishing in January 2016.
