This is Scientific American's 60-Second Science. I'm Steve Mirsky. Got a minute?

The National Safety Council estimates that 28 percent of all highway accidents and deaths are caused by drivers paying poor attention to the road because they’re holding cell phones to their heads. But a study of 200 volunteers finds that one out of every 40 people apparently1 can operate a vehicle just fine while chatting on a phone. In simulated driving tests, anyway. The research by University of Utah psychologists Jason Watson and David Strayer will be published in the journal Psychonomic Bulletin and Review.

Why are there so few great multi-taskers? The researchers say there may be a hidden cost, and that someone might excel at multi-tasking at the expense of other information processing. Or the high-tech2 environment that rewards multi-tasking is too new for the ability to have widely propagated, if there’s a true evolutionary3 advantage to having it.

The researchers want to study so-called supertaskers to find out how their brains do it. Meanwhile, don’t assume you’re one of the very few who can apparently talk and drive safely. There’s a very high probability that you’re not.

Thanks for the minute for Scientific American's 60-Second Science. I'm Steve Mirsky.
