What is cognitive tool delegation?

Cognitive tool delegation is a concept in personal epistemology: A tool is a delegated capability — it does something you could do, but faster, more reliably, or at greater scale.

Example: You need to navigate to an unfamiliar restaurant across the city. You could study a paper map, memorize the route, track landmarks as you drive, and hold the entire spatial model in working memory — turn left at the church, right after the bridge, second exit at the roundabout. Or you could type the address into a GPS app and follow spoken instructions. Both methods get you there. The second delegates spatial reasoning, route optimization, and real-time tracking to an external tool, freeing your attention for traffic, conversation, and the actual experience of driving. You did not lose the ability to navigate. You delegated a capability you possess to a system that executes it faster, with fewer errors, and without consuming the cognitive resource you need for everything else. That is what tool delegation is: not replacing your mind, but redirecting its finite capacity toward work that only your mind can do.

This concept is part of Phase 27 (Delegation Patterns) in the How to Think curriculum, which builds the epistemic infrastructure for delegation patterns.
