Litany of Occam

It is more probable that A, than that A and B.

I can see the appeal here -- litanies tend to have a particular style after all -- but I wonder if we can improve it.

I see two problems:

1. This doesn't convey that Occam's razor is about explanations of observations.
2. In general, one explanation is not a logical "subset" of the other. So the comparison is not between A and A and B; it is between A and B.

Perhaps one way forward would involve a mention (or reference to) Minimum Description Length (MDL) or Kolmogorov complexity.
