Allocate larger time blocks to fewer concurrent tasks rather
Allocate larger time blocks to fewer concurrent tasks rather than fragmenting time into many small slices, because context-switching costs consume 20-40% of effective capacity.
Why This Is a Principle
Derives from Task-switching generates attention residue that persists… (task-switching generates attention residue), Directed Attention as Depletable Resource (attention is finite and depletes), and Working Memory Capacity Limit (working memory limits). The principle: given measurable switching costs, reducing switch frequency by increasing block size produces more effective work. This is prescriptive and quantifiable.
