Newport opens with a bold claim: in our increasingly technological economy, those who can perform deep work will thrive. This chapter establishes the economic argument for why deep work is becoming one of the most valuable skills you can develop.
Newport identifies three groups that will thrive in the new, restructured economy:
Newport focuses on the first two groups because these are positions you can actively work toward. Both require the ability to quickly master hard things and to produce at an elite levelâabilities that depend fundamentally on your capacity for deep work.
To join the ranks of winners in the new economy, you need to develop two core abilities:
Intelligent machines are complicated and difficult to master. To join the group of those who can work well with these machines, you must be able to learn complicated new skills quicklyâand keep learning as the technology evolves.
If you want to become a superstar, mastering the relevant skills is necessary but not sufficient. You must then transform that latent potential into tangible results that people value. In other words: you must produce.
Both abilities depend on your capacity to perform deep work. Without the ability to concentrate intensely, you cannot master difficult subjects, and without sustained focus, you cannot produce work at an elite level.
Newport draws on the research of Anders Ericsson to explain why deep work is essential for mastering complex skills. Deliberate practiceâthe gold standard for skill developmentârequires two things:
The reason deliberate practice works is neurological. When you focus intensely on a specific skill, youâre essentially forcing the relevant neural circuits to fire repeatedly. This repetition triggers myelin developmentâthe white tissue that wraps around neurons and allows them to fire faster and more cleanly.
âTo learn hard things quickly, you must focus intensely without distraction. To learn is an act of deep work.â â Cal Newport
Newport proposes a simple formula that captures the relationship between deep work and productivity:
High-Quality Work Produced = (Time Spent) Ă (Intensity of Focus)
This formula explains why some people seem to accomplish far more than others with the same amount of time. If youâre constantly interrupted or distracted, your intensity of focus drops dramatically, even if youâre nominally âworkingâ for many hours.
Newport profiles Wharton professor Adam Grant, who became the youngest tenured professor at the school while also being its highest-rated teacher. Grantâs secret? He batches his work into intense, uninterrupted stretches. During these periods, he sets an out-of-office auto-reply and focuses completely on writing. This allows him to produce multiple high-impact academic papers per yearâa rate that would be impossible with a fragmented schedule.
One of the chapterâs most important concepts is âattention residue,â drawn from research by Sophie Leroy. When you switch from Task A to Task B, your attention doesnât immediately followâa residue of your attention remains stuck thinking about Task A.
People experiencing attention residue after switching tasks are likely to demonstrate poor performance on that next task. The more intense the residue, the worse the performance. Constantly checking email or social media leaves substantial attention residue that compromises your cognitive capacity.
This is particularly harmful because attention residue is especially thick if your work on the original task was unbounded and of low intensity before you switched. Quick checks of email or social mediaâprecisely because theyâre quickâtend to produce especially problematic residue.
