I think your use of "believe in" is a little suspect here. I'm willing to believe that more than half of all theoretical physicists believe some variant of the MWI is basically right (though the poll can't have been that recent if Feynman was part of it, alas), but that's different from the claim that there are no non-MWI interpretations worth considering, which is something a lot of people, including me, seem to be taking from the QP sequence. Do you believe that that's a majority view, or anything close to one? My impression is that that view is very uncommon, not just in public but in private too...at least outside of Less Wrong.
That sounds correct to me. A physicist who also possesses probability-theory expertise and who can reason with respect to Solomonoff Induction and formal causal models should realize that single-world variants of MWI are uniformly unworkable (short of this world being a runtime-limited computer simulation); but such is rare (though not unheard-of) among professional physicists; and among the others, you can hardly blame them for trying to keep an open mind.
I have several questions related to this:
If you visit any Less Wrong page for the first time in a cookies-free browsing mode, you'll see this message for new users:
Here are the worst violators I see on that about page:
And on the sequences page:
This seems obviously false to me.
These may not seem like cultish statements to you, but keep in mind that you are one of the ones who decided to stick around. The typical mind fallacy may be at work. Clearly there is some population that thinks Less Wrong seems cultish, as evidenced by Google's autocomplete, and these look like good candidates for things that makes them think this.
We can fix this stuff easily, since they're both wiki pages, but I thought they were examples worth discussing.
In general, I think we could stand more community effort being put into improving our about page, which you can do now here. It's not that visible to veteran users, but it is very visible to newcomers. Note that it looks as though you'll have to click the little "Force reload from wiki" button on the about page itself for your changes to be published.
