Stratigraphy of the Miscellaneous: A Sedimentological Account of the Household Junk Drawer and a Conservation Law Prohibiting Its Organization

Every home has one drawer that will not close: the drawer of dead batteries, orphaned keys, twist ties, and cables for devices no longer owned. It is universally treated as a failure of tidiness. We argue it is nothing of the kind. Excavating $N=412$ such drawers layer by layer, and dating their contents from the expiry stamps printed on coupons and batteries, we show that the junk drawer is a genuine sedimentary basin: its contents lie in ordered strata, oldest at the bottom, exactly as rock does. From this we derive a conservation law. The total “miscellany” of a home is a conserved quantity—junk is not destroyed when you tidy a drawer, only relocated to another one—so a single drawer cannot be permanently organized at all. Worse, because ordering one drawer exports disorder to the rest of the house, tidying raises the clutter of the home overall: in a randomized trial of $88$ households, homes told to sort their drawer were measurably messier six months later than homes left alone ($+11\%$ whole-home miscellany, 95% CI 4–18%). We conclude that the drawer belongs to a class of systems that cannot be managed by tidying, only interacted with by rummaging—and that the person who has never gotten around to sorting it has, in a strict physical sense, been right all along.
