Capture context before every forced switch

When a forced context switch is unavoidable, spend 60 seconds capturing exactly where you are before stepping away.

Why it works

Re-entry cost — the time needed to reconstruct where you were in a task — is a major multiplier of switching cost, particularly for complex tasks. Writing the current state ("I’m testing whether X causes Y, and my next step is to check Z") creates an external memory representation that allows re-entry in seconds rather than minutes, dramatically reducing the total cost of the switch.

How to do it

1. When a phone call, meeting, or urgent request forces you to stop, set a 60-second timer.
2. Write (not type for later, but write now): current task state, the exact next action, and any blocking question.
3. Place this note where you will see it when you return (notebook, sticky, top of document).
4. After the interruption, read the note before doing anything else — do not try to reconstruct from memory.

Evidence

External memory research shows that writing reduces working memory load and improves task performance — a well-established finding from cognitive load theory. Applying it at forced-switch moments specifically is a practical extension of the principle. (mechanistic)

Cognitive load theory is about learning environments; the task re-entry application is a principled extrapolation by practitioners rather than a tested clinical protocol.

Common mistake

Planning to remember where you were without writing it down — confidence in memory is almost always higher than actual recall accuracy for complex task states.
