Science once again validates that which you already knew, namely that people walking down the street with their noses buried in their smartphones are a giant pain in the collective patootie.

Students at the University of Bath over in the U.K. did the research, according to the Huffington Post. 

Here’s the deal: It’s not that people are paying more attention to their phones than where they’re going run into you, it’s that they slow down. 

They don’t get the heck out of the way of people who do know where they’re going, and so gum up the whole sidewalk.

Mea culpa, by the way. And c’mon, you do it too, right?
