You don’t see everything you look at.
Five short tests, each built around the same trick: give your attention a job, then place something unmissable just outside it. Most people miss it. Take one to find out if you would.
Attention is a spotlight, not a floodlight
Psychologists call it inattentional blindness: when your attention is absorbed by one task, your brain can fail to register something else in plain view, even something large, unexpected, or moving directly through your field of vision. It isn’t a problem with your eyes. It’s a limit built into how attention works.
The tests on this site put that limit on display. Each one gives you something to focus on, then places something unmissable just outside it — and shows you, directly, how selective your attention really is.
