In order to obtain any measure distribution that differs from the
uniform one (ie contains information), one must have a selection from
the plenitude (or the multiverse if we're talking about that
situation). This selection is made by the observer, and can be
different for different observers.
In a sense, the prior probability "buck" must stop somewhere. The
reason why this is not a problem usually, is because we homo sapiens
share the same universe.
