Stephens argues from an evolutionary and biological angle: humans were wired as hunter-gatherers to focus on one thing at a time (finding food, avoiding danger), not to parallel-process. He uses a direct comparison: given six tasks and one hour, you can either attempt all six simultaneously or single-task each for ten minutes; the latter produces more efficient and effective output despite using the same total time. The mechanism is that context-switching between tasks carries a hidden cost each time attention shifts, so nominally 'doing more at once' actually reduces total throughput. The practical version is to turn off the phone, focus fully on one task for a defined window (he cites 20-30 minutes), then move to the next.

Core principles
- 01Human attention is biologically wired for one task at a time, not parallel processing
- 02Splitting one hour across six tasks produces worse output than giving each task its own dedicated block
- 03Removing the phone during a block matters as much as the timer itself
- 04Single-tasking is a discipline you practice, not a personality trait some people just have
How to run it
- 1
List the competing tasks
Write down everything you feel pressure to do at once, for example the six tasks in Stephens' one-hour scenario.
- 2
Assign each task its own block
Instead of splitting attention across all of them for the full hour, divide the hour into dedicated blocks, one per task.
Pro tip Stephens' example uses roughly ten-minute blocks for six tasks in an hour; adjust block length to task complexity.
- 3
Remove the phone
Physically turn off or put away the phone for the duration of the block so notifications can't force a task switch.
Watch out Leaving the phone visible but silenced still invites a glance that breaks focus.
- 4
Work the single task to the block's end
Stay on the one task for the full 20-30 minute window Stephens describes for deep work, resisting the urge to check on the others.
- 5
Transition to the next task's block
Once the block ends, move cleanly to the next task's dedicated block rather than blending it with the previous one.
In the wild
Stephens poses a direct scenario: six things to do, one hour available. Attempting all six at once for the full hour produces worse results than giving each task a dedicated ten-minute single-tasked block.
→ The single-tasked approach is, in his framing, both more efficient and more effective for the same time investment.
Common mistakes
Treating multitasking as unavoidable for high performers
Citing examples like Elon Musk doing several things at once reinforces multitasking as a status marker, when the underlying biology still favors sequential focus.
Leaving the phone accessible during a focus block
Keeping the phone nearby, even silenced, undermines the block because a glance at it re-triggers task switching.
Is it for you?
Best for
Anyone juggling multiple open tasks in a single work session who wants measurably better throughput without adding hours.
Not ideal for
Roles that genuinely require real-time monitoring of multiple simultaneous inputs (e.g. live incident response) rather than discrete task completion.
