John correctly observes that he hasn't proposed branch counting, but
requires that the Born rule attach probability weights to branches. But
he's wrong that nobody ever proposed branch counting. Even Sean
Carroll, an Everettian, discusses differential branching as a way to
realize the Born rule.

It's not a quote. I made it up (when have I ever put words in

and T's regardless of whether the coin is fair or loaded.
I am sorry. I thought I was responding to Clark's comment on my
position. You are right, according to Everett's theory there will be
equal numbers of heads and tails. across the whole 2^N sequences. And
this occurs regardless of whether the coin is fair or not (regardless
of the 'probability of success'). My point was rather that there is a
head and tail outcome on every trial -- which probably amounts to the
same thing, though with different emphasis.

Where did you get that quote from? It seems that you are indulging in
your standard pastime of putting words into people's mouths. What I
actually said was:
"This is in obvious conflict with Everett's approach in which every
outcome occurs on every trial."
Which is not the same as your suggestion.
