Many worlds is "more true" than Copenhagen, but I think the description
given by "many minds" is closer to the truth of things. According to the
description given by many minds, there is a pre-existing Infinity of
universes, histories, and minds. When any mind receives information which
it didn't have before, (i.e. when it makes a measurement) it doesn't split
or create anything new. Rather, the mind simply differentiates, and the set
of universes/histories compatible with it and this new information it has
learned, changes.
