News correspondent Dan Harris' performance talk explores the myth that the human mind is built to successfully multitask. Harris points out that while computers are built with multiple processors to take on several tasks, the human brain is like one processor built to exclusively take on one project at a time.
Rather than attempt to do several things half-heartedly at once, Harris recommends focusing all your attention on one thing. This way you can guarantee that you are applying all of your mental faculties to tackle one project rather than splitting that energy onto multiple tasks. As Harris rationally puts it, "every time you think you’re multitasking, essentially that’s a short way of saying you’re doing many things poorly."
