A five-minute shutdown ritual for people who keep thinking about work

You close the laptop at six. At 6:40, halfway through chopping an onion, you remember the reply you owe a client. At eleven you're in bed drafting it in your head.

Psychologists have a name for this, and a cheap fix that has worked in lab and workplace experiments.

Unfinished tasks keep running in the background

The old observation is called the Zeigarnik effect: unfinished tasks stay on your mind more than finished ones. (The original memory findings have been hard to replicate; the studies below test something narrower.) In 2011 E. J. Masicampo and Roy Baumeister tested what that does to people. In a series of studies, an unfinished goal led to intrusive thoughts during an unrelated reading task and to worse performance on an anagram task.

Then they tried something simple. They let people write a specific plan for the unfinished goal. The intrusions and the interference went away, even though the goal was still not done. It mattered that people meant it: in one study, the benefit showed up only in those who later carried out their plans.

Sophie Leroy found a related problem at work. When people switch from an unfinished task to a new one, part of their attention stays behind on the old task, and they do worse on the new one. She called it attention residue. Your evening is the new task.

The fix, tested on employees

Brandon Smit took the plan-making idea into the workplace in 2016. He found that employees had a harder time detaching from work goals they hadn't finished, especially ones they cared about. In an experiment, writing end-of-day plans that said where, when and how each unfinished goal would get done increased detachment. It helped most for people who are highly involved in their jobs, the ones who usually find it hard to switch off.

So a shutdown routine doesn't have to finish everything. It has to leave a plan for whatever's left.

A five-minute version

Cal Newport popularized the idea of a shutdown ritual in his 2016 book Deep Work. He ends his day by checking his lists and calendar, then says a set phrase out loud: "Schedule shutdown, complete." Here's a version built on the research above. Adjust it to your job.

1. Skim your inbox and chat once. Look only for things that truly can't wait until tomorrow, and handle those or reply with a time you'll handle them.
2. List what's still open. For each item, write the next concrete step and when you'll do it: "9:30, send Dana the revised quote." This is the part the studies tested, so don't skip it.
3. Look at tomorrow's calendar so it can't surprise you in the morning.
4. Close the tabs and apps you won't need first thing.
5. Close the lid. Make this the signal that the list is done and so is the day.

Newport's spoken phrase gives the routine a definite end, so when a work worry pops up later he can remind himself that he already said it. If you'd feel silly talking to your desk, the lid can do the same job, as long as closing it is something you notice.

Why we put a sound on step five

Maclap plays a short sound when your MacBook lid closes. This is the moment we built it for. When the routine ends in the same pop or click every day, the sound becomes your "shutdown complete."

We haven't run a study on Maclap, and it won't write your plans for you. Step two is the part with evidence behind it. The sound is there to mark the end so you'll notice it. Then you go make dinner, and this time the client email isn't following you around the kitchen.
