I was listening to NPR on my way to the beach on Friday and I found myself wanting to stick my fingers in my ears and sing loudly, “La, la, la, la…,” so disturbing was what I was hearing.
It was a segment on Talk of the Nation, Science Friday August 28 that dealt with a study of multitasking. Apparently people who think they are great at multitasking are not. Apparently they are not only not good at multitasking, but their cognitive abilities are impaired in other areas as well. At least that is what Clifford Nass from Stanford University found in the research he described on NPR’s Science Friday.
So the three abilities we looked at were – the first is filtering: the ability to ignore irrelevant information and focus on relevant information. And I had thought, more than my other two colleagues, that that was a particular gift that high multitaskers had. But in fact, multitaskers are suckers for distraction and suckers for the irrelevant, and so the more irrelevant information they see, the more they’re attracted to it.
The second ability is the ability to manage your working memory, keep it neatly organized, be able to – the way I usually think about it is, imagine having very neat filing cabinets where you carefully and quickly place things in the right cabinet, and when you need the information, you immediately know which filing cabinet to go to. They’re actually much worse at that.

And finally, the biggest surprise to the two other authors of the study, Eyal Ophir and Anthony Wagner, the biggest surprise was that they’re even slower and worse at switching from one task to another. You would’ve thought that, at the very least, would be the key gift of multitaskers, but they’re actually worse.
As if that weren’t bad enough there seems to be some evidence that multitasking impairs other types of thought more generally.
I think the reason it’s so frightening is we actually didn’t study people while they were multitasking. We studied people who were chronic multitaskers, and even when we did not ask them to do anything close to the level of multitasking they were doing, their cognitive processes were impaired. So basically, they are worse at most of the kinds of thinking not only required for multitasking but what we generally think of as involving deep thought.
I don’t think of myself as particularly good at multitasking, but I do it a lot. It seems like a necessity in today’s world. So are we dumbing ourselves down?
