*

*> Well, first there is the question of what you mean by a 1st person
*

*> expectation and by "yourself". There is no 1 of the 10 copies which is
*

*> linked more than the others to the original copy. So depending on the
*

*> definition I would either say that you are only at Brussels, or that you
*

*> are at all three places.
*

*> But for practical purposes (such as, if you knew only German,
*

*> deciding which language to learn before being scanned, English or
*

*> Russian), I would of course say that, after the reconstitution, your
*

*> effective probability of seeing Moscow is 90%, so Russian is more
*

*> "likely" to come in handy.

*

*> OK, not just link it, but say it is directly proportional
*

*> (but see above). But my point is that if you do that you reject the
*

*> RSSA. For example, suppose that a year later (on 1/1/2001), the copies at
*

*> Moscow are destroyed except for one, while at Washington 8 new copies of
*

*> the version of you that has been there are made. During 2000, what is the
*

*> effective probability that you would be at Moscow? It is 90%; next year,
*

*> it is 10%.
*

*> But according to the RSSA that would not be the case. If you
*

*> are 90% likely to be in Moscow in 2000, each type of version of you could
*

*> only "flow into" its own continuation, so the eff. pr. of being at Moscow
*

*> woulkd remain at 90% for 2001. (Chris Maloney would claim that the
*

*> eff. pr. of being at Moscow would be 10% for both years).
*

Interesting way of putting it. I quite agree, the RSSA says that in

1999, the probability of being in Moscow in 2001 is 90%, and 10% of

being in Washington. But then effective probability is not related to

absolute measure, rather the conditional measure - so no problems here.

*> The ASSA, on the other hand, is naturally compatible with the
*

*> simple rule that the effective probability is proportional to the number
*

*> of copies. So do you, in fact, agree with that rule?
