I have four screens on my desk. During phone calls, I turn them all off. Pen. Paper. That's it. I remember more from the call. I can go back a year and read what we actually said, not what I think we said. I know this sounds old school. It works anyway. For a long time, I thought I was just being old-fashioned. Anyone who knows me knows I have a junk drawer full of every tablet ever made. Palm Pilot on one end. Remarkable on the other. Everything in between. Then I read the research. In 2009, a team at Stanford ran a study on heavy media multitaskers. They expected to find something the multitaskers were better at. Filtering, task-switching, memory, something. That was the whole point of the study. They found nothing. Eyal Ophir, the lead author, put it this way: "We kept looking for what they're better at, and we didn't find it." It gets worse. Even when the heavy multitaskers weren't multitasking, their cognitive processes were impaired. The damage traveled with them. A 2018 Stanford review of the next decade of research found not a single published study showing a positive link between heavy multitasking and working memory. Gloria Mark at UC Irvine put a number on what it costs you. After a single interruption, it takes an average of 23 minutes and 15 seconds to fully return to the original task. She also tracked how long we stay focused on any one screen before we switch. In 2004, it was about 2.5 minutes. Today it's 47 seconds. 47 seconds. Heavy multitaskers rate themselves as effective. Testing says otherwise. Busy feels like progress. The data says it mostly isn't. Cal Newport wrote a book called Deep Work in 2016. His argument is simple. The ability to focus on hard problems is getting rarer while it's getting more valuable. Most people have traded that edge for notifications. If you haven't, you have one. I still fight this battle every day. We all know the research. The books aren't hidden. And I still catch myself half-listening to calls with three tabs open, thinking I'm saving time. Saving time from what, exactly? The screens go off for a reason. The pen isn't nostalgia. It's a tool that forces my brain to stay in one place.
