Context switching
Context switching is shifting your attention from one task or project to another. Each shift carries a measurable cost: laboratory task-switching studies consistently find slower responses and more errors immediately after a switch, and reloading the context of complex work, what you were doing, why, and what comes next, takes far longer than the switch itself feels. Heavy switching can consume a large share of a working day while feeling like productivity.

What the research shows
Rogers and Monsell (1995) established the switch cost paradigm: even with full warning, people respond more slowly and less accurately right after switching task rules. For real work the reload cost dominates: Gloria Mark's field studies of office workers found frequent interruption and fragmentation, with self-interruption nearly as common as external interruption, and interrupted work associated with more stress and effort. Multitasking is mostly rapid switching, and it inherits all of these costs.
Why it matters for procrastination
Switching is procrastination's favourite disguise. Hopping to a smaller task feels like work while dodging the hard one, and the accumulated switch costs then make the hard task genuinely harder to start, because its context is never loaded. Batching similar tasks, single-tasking in timed blocks and closing communication tools during focus periods all attack the same lever: fewer reloads per day.

Frequently asked questions
How much time does context switching actually waste?
Honest answer: widely quoted precise figures, like a fixed number of minutes to refocus, are looser than they sound. What is well supported is the direction: switches reliably cost time and accuracy, fragmented days feel more stressful and effortful, and reducing switches gives back real capacity.
