Do this to multitask less
Datum: 2025-10-30 08:17
It has long been established that multitasking is bad for us in several ways, particularly since it makes us perform our tasks poorly. Multitasking is what you do when you jump back and forth between many tasks frequently, rather than working on one task at a time for longer, uninterrupted periods of time. It is easy to end up working this way — especially on days when we have a lot to do and are constantly interrupted.
Obviously, this is not preferable, since the quality of our work suffers and, in addition, it is easy to feel fragmented and (with a sense of inadequacy) feel that we are not really getting anything done.
For you who prefer listening to reading, this post is also available as an episode of the ““Done!”” podcast:
What drives multitasking?
However, there are fairly simple tricks you can use to reduce the devastating multitasking. In a study, researchers Szumowska and Kruglanski look at what causes multitasking and what you can do about it. The results of a series of experiments suggest that:
- the more to-do tasks participants wanted to complete during the day, the more they multitasked (that is, the shorter the time they worked on each task before switching to another)
- the more participants were interrupted in their work, the more they multitasked — especially if what interrupts is both noisy and visible
- if participants selected one of the tasks and decided it was more important to complete during the day, they multitasked less — even if the number of tasks remained the same
Choosing one task above the others
This third result was particularly interesting, I think. The way participants made one of the tasks more important than the others was that the researchers had them name three gains from completing that particular task during the day, as well as three possible hindrances to completing it. By distinguishing one of the day’s tasks as the most important, participants were able to focus more and were less divided between all of the tasks they had to do that day.
Do this
If you want to multitask less in your work, take note of what came out of the aforementioned study.
From your list of everything you want to get done today, choose which task is most important to do today. Just one, when all you have to do is important? Yes, because once you have completed it, you can choose another one, as long as there is time left in the workday.
You can write the task on a PostIt and paste it in where it is literally “in your face” so that there is no doubt about what you most want to get done. You can put a “high priority” label on the task in your digital to-do list or a star if you use Microsoft To-Do. You can highlight the task with a highlighter in your favorite color if you have your to-do list on paper. Or, do something completely different that suits you better to highlight one of your tasks from the rest.
To make the contrast between your chosen task and the others even greater, think of three gains from completing it today and three possible things that might prevent you from doing so.
Throughout the day, note if this highlighting of one of the tasks helps you multitask less. If you get a taste for it — make this method a habit, to use every day or on days when you are extra busy.
Higher quality and more focus
If you select one task from all the day’s tasks and make it your most prioritized task of the day, you will be able to focus on it more easily instead of jumping between many tasks, judging by what Szumowska and Kruglanski’s study suggests. You will be less fragmented, able to deliver with higher quality, and I suspect you will also feel greater satisfaction with what you have accomplished at the end of the day.
How do you do it?
Do you do something similar to what I have described here? Perhaps you are one of those people who, in the late afternoon, choose the three most important tasks for tomorrow. Write and share your thoughts!
