Distributive Cognition

Where does thinking happen? The obvious answer — inside the skull — is too small. Watch a cook in a kitchen: the recipe card holds the steps, the arranged spices hold the order, the timer holds the memory. The thinking is spread across the whole counter.

This is distributed cognition: the mind routinely outsources itself to the world. Lists, calendars, labels, knots in handkerchiefs, things left by the door — each is a piece of thinking parked outside the head.

Far from being cheating, this is the mind's oldest technology. The brain is small and expensive; the notebook is vast and free. Every civilization runs on parked thoughts — ledgers, maps, signs, laws written down.

So build your extensions deliberately. A place for the keys is a decision never to search. A written plan is a hundred remembered intentions. The clever mind is not the one that holds everything inside. It is the one that has wisely arranged the outside.
