If you've recently joined the Less Wrong community, please leave a comment here and introduce yourself. We'd love to know who you are, what you're doing, or how you found us. Tell us how you came to identify as a rationalist, or describe what it is you value and work to achieve.
If you'd like to meet other LWers in real life, there's a meetup thread and a Facebook group. If you've your own blog or other online presence, please feel free to link it. If you're confused about any of the terms used on this site, you might want to pay a visit to the LW Wiki, or simply ask a question in this thread. Some of us have been having this conversation for a few years now, and we've developed a fairly specialized way of talking about some things. Don't worry -- you'll pick it up pretty quickly.
You may have noticed that all the posts and all the comments on this site have buttons to vote them up or down, and all the users have "karma" scores which come from the sum of all their comments and posts. Try not to take this too personally. Voting is used mainly to get the most useful comments up to the top of the page where people can see them. It may be difficult to contribute substantially to ongoing conversations when you've just gotten here, and you may even see some of your comments get voted down. Don't be discouraged by this; it happened to many of us. If you've any questions about karma or voting, please feel free to ask here.
If you've come to Less Wrong to teach us about a particular topic, this thread would be a great place to start the conversation, especially until you've worked up enough karma for a top level post. By posting here, and checking the responses, you'll probably get a good read on what, if anything, has already been said here on that topic, what's widely understood and what you might still need to take some time explaining.
A note for theists: you will find LW overtly atheist. We are happy to have you participating but please be aware that other commenters are likely to treat religion as an open-and-shut case. This isn't groupthink; we really, truly have given full consideration to theistic claims and found them to be false. If you'd like to know how we came to this conclusion you may find these related posts a good starting point.
A couple technical notes: when leaving comments, you may notice a 'help' link below and to the right of the text box. This will explain how to italicize, linkify, or quote bits of text. You'll also want to check your inbox, where you can always see whether people have left responses to your comments.
Welcome to Less Wrong, and we look forward to hearing from you throughout the site.
(Note from MBlume: though my name is at the top of this page, the wording in various parts of the welcome message owes a debt to other LWers who've helped me considerably in working the kinks out)
Actually it's entirely possible to miss a lot of detail while ostensibly sampling broadly. If you sample citizens in Bogota, Mumbai, Taibei, Kuala Lumpur, Ashgabat, Cleveland, Tijuana, Reykjavik, London, and Warsaw, that's pretty darn international and thus a good cross-cultural representation of humanity, right? Surely any signals that emerge from that dataset are probably at least suggestive of innate human tendency?
Well, actually, no. Those are all major cities deeply influenced and shaped by the same patterns of mercantile-industrialist economics that came out of parts of Eurasia and spread over the globe during the colonial era and continue to do so -- and that influence has worked its way into an awful lot of everyday life for most of the people in the world. It would be like assuming that using wheels is a human cultural universal, because of their prevalence.
An even better analogy here would be if you one day take a bit of plant tissue and looking under a microcoscope, spot the mitochondria. Then you find the same thing in animal tissue. When you see it in fungi, too, you start to wonder. You go sampling and sampling all the visible organisms you can find and even ones from far away, and they all share this trait. It's only Archeans and Bacteria that seem not to. Well, in point of fact there are more types of those than of anything else, significantly more varied and divergent than the other organisms you were looking at put together. It's not a basal condition for living things, it's just a trait that's nearly universal in the ones you're most likely to notice or think about. (The break in the analogy being that mitochondria are a matter of ancestry and subsequent divergence, while many of the human cultural similarities you'd observe in my above example are a matter of alternatives being winnowed and pushed to the margins, and existing similarities amplified by the effects of a coopting culture-plex that's come to dominate the picture).
It totally is, but my point was that Eliezer has expressed it's a matter of biology, and if I'm correct in my thoughts he's wrong about that -- and in my understanding of how he feels FAI would behave, this would lead to the behavior I described (FAI explains to Eliezer that he's gotten that wrong).
