Attention Span Dropped to 47 Seconds

Gloria Mark's research reveals a stark collapse: since 2004, our average screen focus has shrunk from two and a half minutes to forty-seven seconds. The culprits aren't just pings and notifications. Sophie Leroy's concept of attention residue shows that unfinished tasks leave mental fog long after you've switched away, while Mark's data proves nearly half of all interruptions are self-inflicted escapes from discomfort. Four guards can reclaim your day: the protected block, the parking note, the capture list, and the ninety-second rule.

You'll learn:

- Why "multitasking" is actually expensive rapid task-switching

- How twenty minutes vanish after each self-interruption

- Why screen breaks drain the same muscle they claim to rest
