What research does show is that we switch screens fast, and each switch costs more than it looks. Here's what that means and 8 practical ways to focus longer. _Darwish ยท 2026-10-27_ You sit down to read one article. Two minutes later you're in a group chat, then a video, then a tab you don't remember opening. If that sounds familiar, you're not broken, and you're not alone. The good news: attention isn't a fixed number you were born with. It responds to how your day and your screens are set up. This guide covers what research actually says about attention span, why switching costs more than it looks, and eight practical steps to focus longer. ## First, the goldfish myth You've probably heard that the human attention span dropped to eight seconds, shorter than a goldfish's nine. It's one of the most shared "facts" about attention online. It doesn't hold up. The figure was traced to a 2015 Microsoft Canada marketing report, but the number didn't come from that report's own research, and later reporting found no reliable source behind it. Psychologists who study attention also point out that there's no single "average attention span." How long you focus depends on the task, your energy and your surroundings. (Goldfish, for the record, learn and remember well.) So if you've been told your brain is now "worse than a fish," you can let that go. ## What researchers actually measure The more useful research comes from Gloria Mark, a professor emerita of informatics at UC Irvine, who has studied how people use computers at work for about two decades. Her team measured something narrower and more practical: **how long people stay on one screen before switching to another.** In her early studies, that was around two and a half minutes. By 2012 it was about 75 seconds. Across her studies from 2016 to 2020, the average was about 47 seconds. Two things are worth keeping in mind: - **This is screen switching, not a test of your brain.** It describes behaviour on devices, not a fixed limit on what you can concentrate on. People still follow a two-hour film or a long conversation without trouble. - **Short screen visits aren't always bad.** Checking a reference or replying to a quick question can be part of good work. The problem is switching you didn't choose. ## Why switching costs more than it looks Every switch has a hidden cost. Sophie Leroy, a professor of management at the University of Washington Bothell, named it **attention residue**: when you move from Task A to Task B, part of your mind stays on Task A. You have less attention left for the thing in front of you. Residue is strongest when you leave something unfinished, when you're interrupted, or when you know you'll have to rush back to it later. Mark's research adds that getting back to an interrupted task can take close to half an hour. Put those together and a "quick check" of your phone isn't quick. It's a small tax on the next 20 minutes. ## Why the feed keeps pulling you back Not all switching comes from you. Most feeds are ranked to keep you watching and scrolling, because that's how the platform earns money. Autoplay, endless scroll and recommended next videos are all built to make the next switch easy and the stop hard. We explain the bigger picture in [What Is the Attention Economy?](https://boslaai.co/blog/what-is-the-attention-economy). That's why willpower alone tends to lose. You're one person against a system tuned by thousands of engineers. The fix is to change the setup, not to blame yourself. ## 8 practical ways to build a longer attention span ### 1. Decide what you're there for before you open anything Before you open a laptop or an app, name one thing you're there to do: "finish the report intro" or "watch lecture 4." A clear target makes it easier to notice when you drift. ### 2. Start with a focus block you can actually hold Don't aim for three hours on day one. Start with 20 to 25 minutes of single-task work, then a short break. The [Pomodoro Technique](https://boslaai.co/blog/pomodoro-technique-guide) is a simple way to do this. Lengthen the blocks slowly as they start to feel easy. ### 3. Close the loop before you switch Since unfinished tasks create the most residue, write a one-line "where I stopped and what's next" note before you move on. Leroy's research calls this a ready-to-resume plan. It lets your mind put the first task down. ### 4. Batch messages instead of answering live Pick set times to check messages and email, for example at the top of each hour. Turn off non-essential notifications in between. Most messages can wait 50 minutes; your focus can't easily recover from 50 interruptions. ### 5. Shape the feed, not just your habits Remove the triggers you know pull you in. Hide Shorts or Reels, turn off autoplay, and use subscriptions or search instead of the home feed when you're working. Our guide to [customizing your YouTube feed](https://boslaai.co/blog/how-to-customize-your-youtube-feed) walks through the built-in settings, and [Website Blocker vs Feed Filter](https://boslaai.co/blog/website-blocker-vs-feed-filter) helps you choose between blocking a site and filtering what it shows. ### 6. Practise long-form on purpose Attention grows with use. Read a full chapter without your phone nearby. Watch a whole lecture at normal speed. Have one conversation without checking a screen. Small, regular reps matter more than one heroic day. ### 7. Take breaks that are actually breaks Scrolling isn't rest; it's more input. Step away from screens: walk, stretch, look out a window, drink water. Mark's work notes that even around 20 minutes in nature can help people feel calmer and more creative. ### 8. Learn your own rhythm Most people have hours when focus comes easily and hours when it doesn't. Track it for a week. Put your hardest work in your best hours, and save email and admin for the low ones. ## How to tell if it's working You don't need a lab. For one week, keep a tally: each time you switch away from your main task without meaning to, make a mark. Then try two or three of the steps above for a second week and compare. You're looking for fewer unplanned switches and longer stretches on the thing you chose, not perfection. ## Where BOSLA AI fits Steps 1 to 4 are about your routine. Step 5 is about your environment, and that's where a tool can help. BOSLA AI is a browser extension that lets you decide what your feed shows you on YouTube, X and LinkedIn: filter topics, blur what you'd rather not see and remove ads, so there's less pulling at your attention while you work. You set the rules, and you can change them anytime. ## The short version Your attention isn't eight seconds long, and it isn't broken. It's being pulled in many directions by screens designed to pull. Pick one target, protect short focus blocks, close loops before you switch, and shape your feed so it works for you. A little direction each day adds up. --- **Sources** - [How to sharpen your attention and meet your goals](https://www.universityofcalifornia.edu/news/how-sharpen-your-attention-and-meet-your-goals-2024) โ€” University of California, interview with Gloria Mark - [There's no such thing as multitasking](https://magazine.washington.edu/theres-no-such-thing-as-multitasking-according-to-business-expert-sophie-leroy/) โ€” UW Magazine, on Sophie Leroy's attention residue research - [The goldfish myth](https://www.warc.com/newsandopinion/opinion/the_goldfish_myth/2806) โ€” WARC, on the origin of the 8-second claim
