A Bayesian agent who goes through an upbringing as a boy and one who goes through an upbringing as a girl will probably not possess identical beliefs about society, the world, humanity, and so on. This is not because one has been held back or misled, nor because one is less rational than the other ... but because two different partial explorations of the same territory do not yield the same map.

The apparent inconceivability (in this thread) of the notion that someone might disagree on a deep level with local memes without being insane is quite amazing. Typical mind fallacy, the lack of realisation that there exist unknown unknowns.

This matters if we care about possessing accurate maps; and it also matters a great deal if what we are trying to map includes things like "the good of humanity" or "coherent extrapolated volition of humankind" or things like that.

Yes. This thread reads like LW is aimed at realising the CEV of well-off programmers in the Bay Area. If you're serious about working for all of humanity, it may conceivably be useful to seriously listen to some who don't already agree with you.
