    The Multitasking Myth: Why Your Brain Can't Handle It

    Best quote from The Multitasking Myth: Why Your Brain Can't Handle It

    “

    What we proudly call multitasking is actually 'switchtasking'—we're rapidly shifting our attention between activities without fully focusing on any single one, which can reduce productivity by up to 40% and temporarily lower your IQ by 15 points.
