Part of your mind stays behind
Meet Marta and the invisible cost of switching.
At nine o’clock, Marta began writing an important report. She closed the door, made coffee, and promised herself that she would focus. Ten minutes later, she checked her inbox. There was nothing urgent, so she returned to the report. Then a message from a colleague appeared. Marta read it, decided to answer later, and went back to work again.
- 01
Why did Marta believe she was creating good conditions for focused work?
By lunchtime, she had been at her desk for three hours, but the report had hardly moved forward. She had not spent hours on social media, and none of her breaks had been long. The problem was the repeated switching itself.
- 02
What actually slowed her progress on the report?
Cal Newport discusses research by business professor Sophie Leroy, who uses the term “attention residue.” When we move from Task A to Task B, our attention does not always move with us immediately. A part of the mind can remain connected to the previous task. We may look focused on the new task while still thinking about the old one.
- 03
In your own words, what is “attention residue”?
- 04
Do you often continue thinking about a message after you have closed it?
This explains why a thirty-second email check can cost more than thirty seconds. The message may stay in your mind after the inbox is closed.

Which interruptions are most difficult for you to forget?
The unfinished task travels with you
See what happened when researchers interrupted people.
In one of Leroy’s experiments, participants first worked on word puzzles. Some were allowed to finish, while others were interrupted and moved to a different activity: reading resumes and making imaginary hiring decisions. Between the two tasks, the researchers tested how much attention was still connected to the puzzles.
- 06
How were the two groups treated differently in Leroy’s experiment?
The people who had been interrupted carried more attention from the first activity into the second. As a result, they performed less effectively on the new task. The effect was particularly strong when the first activity was left unfinished.
- 07
When was attention residue especially strong?
This creates a problem in modern work. We often treat multitasking as the main enemy of concentration. However, many people are not literally doing two things at exactly the same time. Instead, they are moving quickly between a document, an email, a chat, and a meeting. Each switch feels small, but the mind may collect unfinished thoughts from all of them.

What distinction does the text make between multitasking and task switching?
- 09
What do you think happens to the quality of your work after you read a difficult message?
A notification is therefore not only a sound or a few words on a screen. It can introduce a new problem that the brain wants to solve. Even if you choose not to answer, part of your attention may begin preparing an answer.

Would finishing every small task before switching be a good solution? What problems could that create?
Availability is part of some jobs
Move from personal habits to workplace culture.
The obvious solution seems to be simple: turn off notifications, close the inbox, and work on one thing. But this advice does not fit every job. A doctor, customer support worker, or team leader may need to react quickly. For them, availability is part of the work, not a distraction from it.
- 11
Which jobs need rapid responses, and which need long periods of focus?
The real question is not whether all interruptions are bad. It is whether we have chosen when to be available, or whether every message is allowed to choose for us. Some teams create periods for quiet work and separate periods for communication. Others agree that messages do not require an immediate reply unless they are marked as urgent. These rules protect concentration without stopping cooperation.

How would you design a reasonable availability rule for your own workplace?
- 13
Should companies create official hours without meetings or messages?
There is also a cultural problem. A person who answers immediately looks helpful and active. A person who disappears for two hours to solve a difficult problem may look unavailable. As a result, workers can be rewarded for fast responses even when slower, more focused work would create more value.
- 14
Who should be responsible for protecting focus: the worker, the manager, or the whole team?
Managing attention, then, is not only a question of personal discipline. It may also require a team to decide what good work actually looks like.

If fast communication makes work less thoughtful, what should a good workplace value instead?
