NEUROGENETICS INSTITUTE
If it takes under 2 minutes and it's blocking you โ do it now. If it's your opening task โ shrink it until it fits in 2.
Out of the room, not face-down. Presence alone taxes working memory โ even face-down, even off.
One interruption โ minutes of working-memory tax, ~23 min to fully refocus. "Just one check" is never one.
One tab per task. New task opens = old tab closes. Your laptop runs one mode at a time.
Lyrics compete with reading and writing โ fine for maths drills or tidying notes, costly for anything verbal.
Familiar & instrumental is the sweet spot: new tracks invite listening; known tracks fade into background. Silence is never a downgrade.
