Maybe I fired this off too quickly. What I'm trying to say is that
universe B is some specific universe, in which the person refered to as
Nick either has or does not have a rank of less than or equal to 100.
Given that universe B is real, the probability that the real Nick has a
rank <= 100 is either 1 or 0, depending on whether the Nick in universe B
has or does not have a rank <= 100. Ignoring computational limitations, it
is not rational for anyone to assign 1/2 to this conditional probability.
