Synched Blinks Avoid Data Loss
A study in the Royal Society journal Biological Sciences shows that humans will synchronize their blinking when confronted with visual info, indicating that we time our blinks to minimize the chances we'll miss seeing anything important. Karen Hopkin reports

You’ve heard of synchronized swimming. But what about synchronized blinking? No, it’s not a new Olympic sport for slackers. It’s something that seems to happen when we watch a video. Because none of us want to miss the good parts.
If you stop to add it up, humans spend a lot of time not looking. We blink every couple seconds, which means we lose about six seconds out of every minute of viewing time. So 10 percent of the time we have no visual information coming in. Yet we rarely notice this interruption of service.
That’s because we tend to time our blinks so that we don’t get left in the dark. Or so says a report in the Royal Society journal BiologicalSciences. Fourteen people watched a couple episodes of Mr. Bean. And it turns out they all tended to blink at the same moments: just after Bean finished doing something stupid or when the camera showed a long shot with nothing much going on. Such synchronized eye-shutting did not happen when the subjects watched a video of fish swimming around a tank.
So when we need to pay attention, we keep our eyes open. Until we see whether Mr. Bean gets through his holiday in one piece.

It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.
There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
