Brent,
If as you say "in the multiverse everything happens and infinitely
many times"
then there can be only one multiverse,
I think I agree, Richard, but you should perhaps added precisions:
like saying everything *consistent* (in some theory) happens,
infinitely many times.
Computationalism entails that every relative computational states is
realized in infinitely many universal number relations, and the
physical realities are first person plural sort of projections.
which negates a number of cosmology theories like Linde's Chaotic
Inflation Cosmology. But then the potential he used provides the
best fit to BICEP2 gravitational-wave data. Perhaps it is the
multiverse that is falsified?
That would falsify computationalism, but who knows.

Well OK, but what I've read (and indeed observed and experienced
throughout my life) indicates that people, and most animals who
care for their young, employ strategies which could (roughly) be
described as male-risky, female-play-it-safe (or at least safer).
E.g. it's the male grasshoppers who
keep me awake with their racket, the male birds who wake me in the
morning with THEIR racket, peacocks with the big showy tails, male
bower birds who expend the energy to make the bowers - all males
employing (relatively) risky strategies to attract females.
(Because, you see, we're just naturally fabulous and you guys have
to make the running. Sorry!)
Kent's idea would be to look around and see whether people were
overwhelmingly type A or type B. If MWI is true they should be
type B, if false type A.
Yes, I realise what he was saying. I don't think it makes much
sense, because it would require people to believe in the existence
of a multiverse before they could formulate a reproductive
strategy involving that knowledge, and the idea of a multiverse
has only existed for about 50 years.
Not "believe in", just believe MWI is possibly true. But they
wouldn't actually have to have any opinion; that's just a way to
explain it. Presumably evolution would have already made the
choice and we'd all be overwhelmingly either A type or B type,
whether we knew it or not. The problem would be finding out which
we are if it's just in our genes and not necessarily consciously
available.
I'd say more of problem for the test is that the aren't really two
choices which are passed on genetically. There's really nothing to
limit one to just replacement even if there's only one universe.
Otherwise, I'd expect people to act as though they are in a single
universe, regardless of whether that is so, because that's how
things appear to be. I'd expect genes to exhibit a similar
strategy - they aren't (can't be) "interested" in what happens in
a parallel world which can't communicate with the one they're in.
There shouldn't be any split along gender line.
Well there is, at least in my experience (and in various books,
articles, nature documentaries and so on that I've come across).
Indeed, apart from a few die-hard feminists I don't know of anyone
who still adheres to the notion that people are "blank slates" and
that gender roles are purely assigned by culture (humans exhibit
sexual dimorphism, and brain scans indicate that it doesn't
magically stop at our necks. Plus, why would blank-slatism only be
true of us, but not the rest of the animal/fish/insect kingdom
where it - often blatantly - isn't the case?)
Anyway, that's why I don't think one can sensibly analyse an
entire species' reproductive strategy to see if it was A or B (or
something else), because reproductive strategies tend to be gender
specific. It seems like a daft idea - maybe it's a guy thing? ;-)
I don't understand your reasoning. Sure guys are less risk
averse. But A vs B is pure win-or-lose depending on whether MWI is
true or not. If MWI is true then strategy B is the winner no
matter whether you're male or female...and not by a little bit or
just probabilistically, but exponentially, overwhelmingly better.
If MWI is false and there's just one universe then B is an
absolute, zero survivors loser.
The thing is even if MWI is true or not... strategy A or B are
simply "idea" with no referent in the reality (even as
possibility)... the 0.5 probability of going extinct at the next
gen simply refer to nothing real in our reality, same thing for the
"steady" reproduction... so I can't see how an idea pulled from a
hat could possibly "test" anything...
I agree. I just thought it was an interesting idea that 'natural
selection' might act differently in multiverse than a universe. The
example made up by Kent seems highly unrealistic - but then people
keep saying that in the multiverse everything happens and infinitely
many times.
