Attention residue is why switching costs so much
When you switch tasks, part of your attention stays on the previous one for several minutes. That is why a day of ten small interruptions produces far less than the arithmetic suggests, and why the recovery item on this scale predicts output better than the raw block-length item.
Fix the environment before questioning your brain
Most low scores here are produced by notification design and open-tab habits, not by an attention disorder. Change the environment for two weeks and re-score. If the score barely moves and the pattern has been lifelong and pervasive, the ADHD screener is a reasonable next step with a clinician.
FAQ
Does a low score mean I have ADHD?
No. ADHD is defined by lifelong, pervasive symptoms causing impairment across settings — not by a distractible year in a job with Slack open. Only a clinician can assess it.
How long should a deep work block be?
Most people do best at 45–90 minutes. Longer is not automatically better; consistency is what compounds.
Does the phone-in-another-room thing actually help?
Yes — studies of mere phone presence find measurable reductions in available working memory even when the phone is face down and silent.
