I agree with these two posts; better than I could've said it.
On what ground are we to say that the "simplest" explanation is most realistic?
It's an entirely arbitrary assumption.
The idea that the universe "out there" must be in some way "simple" (and to a human - often culture-specific - notion of simplicity at that) is a completely a priori assumption which should not have a great deal of influence over either science or the social 'sciences' (though I admit it does not have some value in the shaping hypothesis).
