More evidence that multitasking doesn't work, so why do so many bosses insist on it?
From the WSJ's Cubicle Culture
Multitasking, a term cribbed from computers, is an information age creed that, while almost universally sworn by, is more rooted in blind faith than fact. It's the wellspring of office gaffes, as well as the stock answer to how we do more with less when in fact we're usually doing less with more. What now passes for multitasking was once called not paying attention.

Employers continue to seek out jugglers despite decades of research showing that humans aren't great multitaskers. (And in the case of distracted driving, we're downright dangerous.)
"Multitasking doesn't look to be one of the great strengths of human cognition," says James C. Johnston, a research psychologist at NASA's Ames Research Center. "It's almost inevitable that each individual task will be slower and of lower quality."

While multitaskers seem to be accomplishing a lot, they are in most cases literally just going through the motions. It is easy for our brain to schedule many different tasks, one after the other. And we'll gamely set out doing those tasks, some of which require little extra brain input and some of which require a lot. As a result, says Hal Pashler, director of the Attention and Perception Laboratory at the University of California, San Diego, "your mouth can be moving while your brain is elsewhere."
