In fact All Universe's Hypotheses (of which the Mulitverse, or MWI is
but one) have the property that the ensemble of universes is simpler
than any one member of the ensemble. This point is made in Tegmark's
paper, but perhaps is more clearly formulated in Schmidhuber's
paper. So Occam's razor actually favours an AUH over a simple reality!
Turned around another way, the AUH actually explains why Occam's razor
actually works - see "Why Occam's Razor" in my publications list which
you can get from my website.
