Stanford professor Clifford Nass takes it one step further and argues that “multitaskers are terrible at every aspect of multitasking.” After using fMRIs (functional magnetic resonance imaging) to study the brain while it was in juggling mode, he found that people who regularly multitasked were “terrible at ignoring irrelevant information, terrible at keeping information in their head nicely and neatly organized, and terrible at switching from one task to another.”
