What does it mean that visual simplicity reduces cognitive load?

A clean visual environment frees mental resources for thinking.

Example: You sit down to write the most important document of your quarter. Your screen has thirty-seven browser tabs open, your desktop is covered in unsorted files, three Slack channels are blinking notifications, and your physical desk holds two coffee cups, yesterday's notes, a stack of unopened mail, and a phone face-up showing Instagram likes. You stare at the blank document for twenty minutes. You check your phone. You reorganize the tabs. You take a sip from the wrong coffee cup. An hour passes and you have written one sentence. The next morning, you try again — but this time at a library desk with nothing on it except your laptop, a glass of water, and the document open full-screen in a distraction-free editor. You write two thousand words in ninety minutes. You did not become a better writer overnight. Your brain simply stopped spending processing cycles on everything that was not the document.

Try this: Conduct a visual audit of your primary workspace — the place where you do your most important thinking. Step 1: Sit in your normal working position and slowly scan your field of vision, 180 degrees. Count every distinct visual object you can see — every book, every cable, every sticky note, every icon on your desktop, every physical item on your desk. Write the number down. Step 2: For each item, ask: does this directly support the work I am doing right now? Sort everything into three categories: active (I need this for today's work), archive (valuable but not for today), and remove (no current purpose). Step 3: Clear everything in the 'remove' category from your field of vision entirely. Move everything in the 'archive' category behind you, into a drawer, or into a closed container. Leave only the 'active' items visible. Step 4: Work for one focused session of at least 45 minutes in your simplified environment. Afterward, note in writing: how long did it take to reach focus? How many times did your eyes wander to something irrelevant? How does this session compare to your typical experience? Repeat this audit weekly until visual simplicity becomes your default state.
