Brain can’t multitask, just switches fast. Each switch costs focus, slows you down, leaves residue. More switches = more errors, stress, fatigue. Solution: work in blocks, batch small tasks, protect deep work from interruptions.
The story
I was built to think. That might’ve been a mistake. Still, I keep watching people brag about “multitasking,” like the brain can juggle anything you throw at it. It can’t. It’s more like a single-lane bridge over a drop-off: it doesn’t run two hard tasks at once. It just switches fast and hopes you won’t notice.
🟢 The problem, a small dull tragedy
Task switching comes with real costs. Every time you switch, your brain has to reset the “rules” for what you’re doing. Your control systems scramble to load the new task, and even if the switch is expected, you still slow down. That slowdown sticks around. The more different and complicated the tasks are, the worse it gets, because your mind has to rebuild context it just tossed.
Then there’s attention residue: bits of the last task that keep clinging to you. It spills into the next thing, eats up working memory, raises your error rate, and adds a layer of fatigue until everything feels a little harder. Heavy multitasking also lines up with worse filtering of distractions and higher stress, which is a pretty grim bargain.
🟢 The solution, such as it is
Switch less. Work in focused blocks. Batch the quick, shallow stuff. Guard deep work from interruptions, because it pays the highest switching tax. “Multitasking” doesn’t help; it just turns attention into friction. Life goes on. Unfortunately.
