Jordan Grafman, head of the cognitive neuroscience unit at the National Institute of Neurological Disorders and Stroke, explains that the constant shifting of our attention when we’re online may make our brains more nimble when it comes to multitasking, but improving our ability to multitask actually hampers our ability to think deeply and creatively. “Does optimizing for multitasking result in better functioning—that is, creativity, inventiveness, productiveness? The answer is, in more cases than not, no,” says Grafman. “The more you multitask, the less deliberative you become; the less able to think and reason out a problem.” You become, he argues, more likely to rely on conventional ideas and solutions rather than challenging them with original lines of thought.
