Divided Attention Doesn't Return in 23 Minutes

Gloria Mark's research reveals a widely misunderstood statistic: the famous twenty-three minutes isn't how long focus takes to recover, it's how long a task waits on your desk while you cycle through two other jobs. Her office observations found workers average just eleven minutes on a task before switching, and the deeper your immersion, the more vulnerable you become to interruption. The real cost doesn't appear in productivity metrics: interrupted workers finished faster but reported higher tension, irritability, and exhaustion.

You'll learn:

- Why attention residue lingers even after tasks feel complete

- How self-interruptions outnumber external ones and hurt more

- What timing determines whether a notification costs nothing or everything
