The myth of multitasking

Dave Crenshaw

4 ideas

  1. Switchtasking, not multitasking

    The brain cannot perform two active tasks at once; it rapidly switches between them. What feels like multitasking is really serial switching.

  2. Every switch costs time and accuracy

    Each context switch adds re-orientation delay and increases errors, making the switching approach slower overall. The hidden tax accumulates across a day.

  3. Protect blocks of single-focus time

    Schedule dedicated attention on one task and separate it from interruptions and background work. Structure, not willpower, preserves focus.

  4. The coach-and-executive dialogue

    The lesson is dramatized through a consultant showing a harried executive the true cost of her constant switching. The narrative format makes the principle concrete.
