See if you can get through this very short blog post without getting distracted. Devote all your energy and attention to it. Why? Because, as The New York Times reports,
multitasking, that bulwark of anemic résumés everywhere, has come under fire in recent years. A 2014 study in the Journal of Experimental Psychology found that interruptions as brief as two to three seconds — which is to say, less than the amount of time it would take you to toggle from this article to your email and back again — were enough to double the number of errors participants made in an assigned task.
Earlier research out of Stanford revealed that self-identified “high media multitaskers” are actually more easily distracted than those who limit their time toggling.
So, in layman’s terms, by doing more you’re getting less done.
