Multi-Tasking is Bad for the Brain, Says Stanford Report
Let me tell you, I am someone who generally has too many tabs open at a time, if you know what I mean. I tend to think multitasking makes me more productive, but recently I’ve been assessing this idea of “going nowhere fast” and realized that part of my problem was trying to do too much at once.
A study out of Stanford University validated this, as it found that people who regularly multitask (especially across digital platforms) actually struggle more with focus, memory, and cognitive control. In controlled tests, heavy multitaskers performed worse than those who focused on one task at a time.
They had difficulty filtering out irrelevant information, meaning distractions pulled their attention more easily. They also struggled with memory and were unable to organize and retain information as effectively. Even when switching between tasks, something multitaskers are assumed to be good at, they underperformed.
Researchers found no cognitive advantage to multitasking. In fact, one of the most striking conclusions was that heavy multitaskers were, in their words, “suckers for irrelevancy,” meaning they were more easily distracted and less able to stay on task (Hi, it’s me!)
What we call multitasking is really just rapid task-switching, and every switch comes with a mental cost.
So, along with my new morning shifts, I’ve been trying to do one thing at a time. Not perfectly, but intentionally. And the difference is noticeable. Less noise. More clarity. Things actually get done. Sometimes doing less at once is what allows you to do anything well.
