    "abstract": "In Everett\u0027s many worlds interpretation, quantum measurements are considered\nto be decoherence events. If so, then inexact decoherence may allow large\nworlds to mangle the memory of observers in small worlds, creating a cutoff in\nobservable world size. Smaller world are mangled and so not observed. If this\ncutoff is much closer to the median measure size than to the median world size,\nthe distribution of outcomes seen in unmangled worlds follows the Born rule.\nThus deviations from exact decoherence can allow the Born rule to be derived\nvia world counting, with a finite number of worlds and no new fundamental\nphysics.",
