        I discussed this one, decision theory in the MWI, with Wei Dai
pretty thoroughly a while ago; look it up.
        Basically, your decisions *do* still determine the outcome, just
like in a single-universe deterministic model. Which is the same as
saying that the laws of physics + initial conditions determine the
outcome; just another way of talking about the same thing, as you are not
something outside of physics.

        There is no free will; in fact, as I say above, realizing that
solves the problem. As for "1st person" you will not be surprised that I
see no basis for such distinctions.
