Science Finally Has an Explanation for Why the Clock Slows down When You Stare at It

Time spent at study goes as slow as molasses in an ice field, while time spent at play goes quicker than hot broth flowing down a slide on a July day.

But when you’re sitting at your desk, periodically checking the clock, you can swear that the darn thing isn’t moving. And it’s not just a one-off occurrence, time proves to be a flat circle and it just keeps on happening day after day and week after week. You haven’t lost your marbles though. As reported by Popular Science, there’s a scientific explanation why you feel so chronologically crippled by that analog on the wall.

The phenomenon is called the “stopped-clock illusion,” and it has to do with your brain’s anticipatory ability. According to Amelia Hunt, a neuroscientist at the University of Aberdeen in Scotland, the brain readies the retina for a predicted outcome so that we’re mentally prepared for the most likely outcome.  This anticipatory reflex is designed so that we aren’t mentally caught off guard, but it comes back to bite us when counting down the hours.

In short, your brain makes a map which is too far ahead, and when you look back at the clock, those hands are all off. That’s not where they’re supposed to be, thinks your brain, causing a bit of a short circuit, a bit more mental fog, and in turn, a slower-seeming day.
