There are more distractions today than ever before.
I can now count more than half a dozen ways that I can be interrupted while writing this article. Phone calls, text messages, Slack messages, people stopping by my office, Facebook notifications, and emails are all fighting for my attention while I’m trying to focus.
And I am easily distracted.
If you ask anyone, they are likely to compare me to that dog from the movie Up who regularly diverts his attention whenever he thinks he hears a squirrel.
Computer Multitasking can be defined as “the concurrent execution of multiple tasks (also known as processes) over an extended period of time.” The brain is just like a biological computer, right? So why wouldn’t I be able to multitask just like it does? I used to think that I could effectively work on several different things at once rather than focusing on one thing at a time. However, the brain isn’t a computer, and this isn’t how it works.
Instead, what you are doing when you think you are multitasking is switching your attention from one task to another. Linda Stone, a former executive at Apple and Microsoft, coined the phrase “continuous partial attention” to describe this activity. You may feel like you can accomplish more; however, using continuous partial attention as your default leads to feelings of being overwhelmed and unfulfilled.
There’s also the science behind this. A few years ago, I read the book “The Organized Mind” by Daniel J. Levitin. Levitin talks about how we live in a world of unprecedented information overload and how to manage it from a neuroscientific perspective. There is no such thing as multitasking. Functional magnetic resonance imaging of the brain has shown how we essentially have a switch in our brain that allows us to change our focus from one thing to another and cannot pay focused attention to two things simultaneously.
This switching from task to task also comes at a considerable energy cost. Even though it only takes a fraction of a second to switch from focusing on one task to another, several studies estimate that it can add up to a 40% decrease in actual productivity. It takes energy to change your focus and then more energy to re-focus on the task you were initially working on. It’s more efficient to work on one thing, finish it, and then go on to the next one.

There are also some negative social costs if you’re constantly switching your attention to other things when conversing with someone or in a meeting. It’s hard to feel listened to when the other person is looking at their phone or checking their email. Because I’m easily distracted by shiny objects, I need to focus on making sure I’m not diverting my attention to anything else in these situations.
If you still don’t believe me, try to focus on one thing at a time for a day or two and see what happens. Close your email while you work on some project. Stop looking at your phone during meetings. Focus on one thing at a time. I think you will be surprised at how much more you get done.
