Batch similar tasks
Group same-mode tasks together so you switch contexts less often.
Key takeaways
- What it is: Group same-mode tasks together so you switch contexts less often.
- Why it works: Switch cost is largest when the two tasks demand different cognitive sets (different tools, rules, or mindsets). Batching similar work keeps you in one cognitive set across many items, so you pay the reconfiguration cost once instead of repeatedly. The savings are in avoided switches, not in doing each item faster.
- Evidence: Plausible mechanism, limited direct outcome data.
- Avoid: Batching by project rather than by cognitive mode, so you still flip between writing, calculating, and deciding within the "batch" and keep paying switch costs.
Why it works
Switch cost is largest when the two tasks demand different cognitive sets (different tools, rules, or mindsets). Batching similar work keeps you in one cognitive set across many items, so you pay the reconfiguration cost once instead of repeatedly. The savings are in avoided switches, not in doing each item faster.
How to do it
- 1Sort tasks by mode: writing, calls, admin, decisions.
- 2Run a block dedicated to one mode rather than interleaving modes.
- 3Process small same-type items (emails, approvals) in one sitting instead of as they arrive.
What the evidence says
MechanisticBatching follows directly from switch-cost research: fewer between-mode switches means less cumulative reconfiguration cost. The principle is well-grounded mechanistically.
Honest caveat: The underlying switch-cost science is strong; the specific productivity gain from any batching scheme depends on your task mix and is not a fixed number.
Common mistake
Batching by project rather than by cognitive mode, so you still flip between writing, calculating, and deciding within the "batch" and keep paying switch costs.
IX Coach helps you group your day by cognitive mode rather than by project, and protects each block so similar work actually runs together.
