For most of human history, doodling was regarded as a pointless distraction. Then scientists decided to ask an important question: Why do we do it?
In 2009, a psychologist in England did a study. She divided people into two groups and had both groups listen to a recording of a long list of names. One group doodled shapes while listening, and the other group didn’t. In the end, the doodlers recalled 29 percent more information than the non-doodlers.
“We think of doodling as something you do when you lose focus,” says doodle expert Sunni Brown. “In reality, it’s what you can do to stop yourself from losing focus.”
Here’s how it works: When you’re learning new information, your brain can get tired and start to daydream about scoring a soccer goal or eating delicious, cheesy pizza. You might even fall asleep.
But if you doodle, your brain stays active. It’s enough to keep you awake—but it’s not so distracting that you stop paying attention.
