Notifications: who they really serve

Each ping is a small interruption someone designed. How to keep the useful ones and lose the rest.

The idea

Every notification is an interruption that someone designed. Some are genuinely useful — a message from family, a reminder you set. Many exist mainly to bring you back into an app: likes, suggestions, “you might have missed”, “someone viewed your profile”.

Even a notification you don’t open costs something. In one experiment, people doing an attention task made more errors after simply receiving a notification, even without looking at it. Other studies found that people who batched their notifications into a few times a day felt less stressed and more in control.

The fix isn’t to miss everything that matters. It is to decide, deliberately, what is allowed to interrupt you: people over apps, urgent over interesting, and the rest gathered up and checked when you choose.

Why it works

Notifications are the most direct way your phone pulls your attention. Cutting the unnecessary ones is one of the quickest, easiest changes with a noticeable effect on focus.

A real example

The situation

Nusrat’s phone buzzes over a hundred times a day — shopping apps, games, group chats, news and social media. She feels jumpy and scattered.

What happened

She spends ten minutes turning off everything except calls and messages from people, and sets group chats to silent. The next day her phone buzzes eleven times. She checks the rest twice a day and misses nothing important.

The takeaway

A few minutes in settings bought back hundreds of interruptions a week.

Use this when you are…

• your phone buzzes more than you can keep up with
• you feel jumpy or unable to settle
• setting up a new phone or app

Common mistakes

• Leaving every app’s default notifications on.
• Muting everything and then compulsively checking in case you missed something — decide what can reach you instead.
• Treating badges and counters as tasks. They are designed to feel unfinished.

What the evidence says

Emerging evidence: Early or mixed research looks promising, but it is too soon to be confident. Treat it as worth trying, not proven.

Experiments show notifications can disrupt attention even when ignored, and studies of batching notifications found improvements in stress and focus. These are relatively small and short studies, so the size of the benefit is still uncertain.

Where this comes from: Attention and task-switching research; Research on digital media and wellbeing.

Fields that study this: Behavioural science, Neuroscience.

Try it now: The notification cut

1. Open your phone’s notification settings.
2. Keep only people (calls, direct messages) and anything genuinely time-sensitive.
3. Turn off the rest, or set them to deliver quietly.

Questions to think about

• Which notifications would you genuinely miss if they stopped?
• Which ones mostly exist to bring you back into an app?

Try this today

Turn off notifications for three apps that don’t need to interrupt you.

Afterwards, ask yourself

After cutting notifications, how many did you actually miss, and how did your days feel?

Words in this lesson

• Notification — An alert from an app or device designed to pull your attention back to it.
• Context switching — Moving attention from one task to another. Each switch costs time and focus, even when it feels instant.
