After applying “shut up and calculate” to RQM the results are identical to the results of applying “shut up and calculate” to MWI,
This isn’t actually correct- there is not a “shut-up-and-calculate” version of many world’s- without the born probabilities you can’t calculate anything. Maybe someday Deutsch,Wallace or some other enterprising many worlds advocate will show us a way to do calculations without the measurement postulate. That hasn’t happened yet, so many worlds does not let us calculate. As far as I know, this inability to calculate is the primary reason physicists reject it.

I’m very curious as to why I’m being downvoted for expressing this sentiment, if any down voter cares to explain, I’d be much obliged.
