A neuroscientist just proved multitasking is a myth and makes you 60% slower — Live experiment, on camera.
He writes “I’m a great multitasker” + 1–20.
Straight through: 31 seconds.
Then she makes him switch.
Letter. Number. Letter. Number.
He falls apart.
Forgets where he is.
Restarts every switch.
By 30 seconds he’s only at 40%.
60% slower.
Same task.
Same person.
Only difference was switching.
She calls it switch cost.
Attentional residue.
The baggage you drag from one thing into the next.
Average knowledge worker does this all day.
2+ hours lost.
Every single day.
