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, what you value, how you came to identify as a rationalist or how you found us. You can skip right to that if you like; the rest of this post consists of a few things you might find helpful. More can be found at the FAQ.

(This is the fourth incarnation of the welcome thread, the first three of which which now have too many comments. The text is by orthonormal from an original by MBlume.)

A few notes about the site mechanics

Less Wrong comments are threaded for easy following of multiple conversations. To respond to any comment, click the "Reply" link at the bottom of that comment's box. Within the comment box, links and formatting are achieved via Markdown syntax (you can click the "Help" link below the text box to bring up a primer).

You may have noticed that all the posts and 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. This immediate easy feedback mechanism helps keep arguments from turning into flamewars and helps make the best posts more visible; it's part of what makes discussions on Less Wrong look different from those anywhere else on the Internet.

However, it can feel really irritating to get downvoted, especially if one doesn't know why. It happens to all of us sometimes, and it's perfectly acceptable to ask for an explanation. (Sometimes it's the unwritten LW etiquette; we have different norms than other forums.) Take note when you're downvoted a lot on one topic, as it often means that several members of the community think you're missing an important point or making a mistake in reasoning— not just that they disagree with you! If you've any questions about karma or voting, please feel free to ask here.

Replies to your comments across the site, plus private messages from other users, will show up in your inbox. You can reach it via the little mail icon beneath your karma score on the upper right of most pages. When you have a new reply or message, it glows red. You can also click on any user's name to view all of their comments and posts.

It's definitely worth your time commenting on old posts; veteran users look through the recent comments thread quite often (there's a separate recent comments thread for the Discussion section, for whatever reason), and a conversation begun anywhere will pick up contributors that way. There's also a succession of open comment threads for discussion of anything remotely related to rationality.

Discussions on Less Wrong tend to end differently than in most other forums; a surprising number end when one participant changes their mind, or when multiple people clarify their views enough and reach agreement. More commonly, though, people will just stop when they've better identified their deeper disagreements, or simply "tap out" of a discussion that's stopped being productive. (Seriously, you can just write "I'm tapping out of this thread.") This is absolutely OK, and it's one good way to avoid the flamewars that plague many sites.

EXTRA FEATURES:

There's actually more than meets the eye here: look near the top of the page for the "WIKI", "DISCUSSION" and "SEQUENCES" links.

LW WIKI: This is our attempt to make searching by topic feasible, as well as to store information like common abbreviations and idioms. It's a good place to look if someone's speaking Greek to you.

LW DISCUSSION: This is a forum just like the top-level one, with two key differences: in the top-level forum, posts require the author to have 20 karma in order to publish, and any upvotes or downvotes on the post are multiplied by 10. Thus there's a lot more informal dialogue in the Discussion section, including some of the more fun conversations here.

SEQUENCES: A huge corpus of material mostly written by Eliezer Yudkowsky in his days of blogging at Overcoming Bias, before Less Wrong was started. Much of the discussion here will casually depend on or refer to ideas brought up in those posts, so reading them can really help with present discussions. Besides which, they're pretty engrossing in my opinion.

A few notes about the community

If you've come to Less Wrong to discuss a particular topic, this thread would be a great place to start the conversation. By commenting 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.

If your welcome comment starts a huge discussion, then please move to the next step and create a LW Discussion post to continue the conversation; we can fit many more welcomes onto each thread if fewer of them sprout 400+ comments. (To do this: click "Create new article" in the upper right corner next to your username, then write the article, then at the bottom take the menu "Post to" and change it from "Drafts" to "Less Wrong Discussion". Then click "Submit". When you edit a published post, clicking "Save and continue" does correctly update the post.)

If you want to write a post about a LW-relevant topic, awesome! I highly recommend you submit your first post to Less Wrong Discussion; don't worry, you can later promote it from there to the main page if it's well-received. (It's much better to get some feedback before every vote counts for 10 karma- honestly, you don't know what you don't know about the community norms here.)

If you'd like to connect with other LWers in real life, we have meetups in various parts of the world. Check the wiki page for places with regular meetups, or the upcoming (irregular) meetups page.

There's also a Facebook group. If you've your own blog or other online presence, please feel free to link it.

If English is not your first language, don't let that make you afraid to post or comment. You can get English help on Discussion- or Main-level posts by sending a PM to one of the following users (use the "send message" link on the upper right of their user page). Either put the text of the post in the PM, or just say that you'd like English help and you'll get a response with an email address.

A note for theists: you will find the Less Wrong community to be predominantly atheist, though not completely so, and most of us are genuinely respectful of religious people who keep the usual community norms. It's worth saying that we might think religion is off-topic in some places where you think it's on-topic, so be thoughtful about where and how you start explicitly talking about it; some of us are happy to talk about religion, some of us aren't interested. Bear in mind that many of us really, truly have given full consideration to theistic claims and found them to be false, so starting with the most common arguments is pretty likely just to annoy people. Anyhow, it's absolutely OK to mention that you're religious in your welcome post and to invite a discussion there.

A list of some posts that are pretty awesome

I recommend the major sequences to everybody, but I realize how daunting they look at first. So for purposes of immediate gratification, the following posts are particularly interesting/illuminating/provocative and don't require any previous reading:

More suggestions are welcome! Or just check out the top-rated posts from the history of Less Wrong. Most posts at +50 or more are well worth your time.

Welcome to Less Wrong, and we look forward to hearing from you throughout the site.

Hi, I'm Liz.

I'm a senior at a college in the US, soon to graduate with a double major in physics and economics, and then (hopefully) pursue a PhD in economics. I like computer science and math too. I'm hoping to do research in economic development, but more relevantly to LW, I'm pretty interested in behavioral economics and in econometrics (statistics). Out of the uncommon beliefs I hold, the one that most affects my life is that since I can greatly help others at a small cost to myself, I should; I donate whatever extra money I have to charity, although it's not much. (see givingwhatwecan.org)

I think I started behaving as a rationalist (without that word) when I became an atheist near the end of high school. But to rewind...

I was raised Christian, but Christianity was always more of a miserable duty than a comfort to me. I disliked the music and the long services and the awkward social interactions. I became an atheist for no good reason in the beginning of high school, but being an atheist was terrible. There was no one to forgive me when I screwed up, or pray to when the world was unbearably awful. My lack of faith made my father sad. Then, lying in bed and angsting about free will one night, I had some philosophical revelation, and it seemed that God must exist. I couldn't re-explain the revelation to myself, but I clung to the result and became seriously religious for the next year or so. But objections to the major strands of theism began to creep up on me. I wanted to believe in God, and I wanted to know the truth, and I found out that (surprise) having an ideal set of beliefs isn't compatible with seeking truth. I did lots of reading (mostly old-school philosophy), slowly changed my mind, then came out as an atheist (to close friends only) once the Bible Quiz season was over. (awk.)

At that point I decided to never lie to myself again. Not just to avoid comforting half-truths, but to actively question all beliefs I held, and to act on whatever conclusions I come to. After hard practice, unrelenting honesty towards myself is a habit I can't break, but I'm not sure it's actually a good policy. For example, a few white lies would've helped me move past a situation of extreme guilt last year.

Anyway, more recently, I read HPMOR and I'm now reading Kahneman's Thinking, Fast and Slow. I'm slowly working through the Sequences too. I always appreciate new reading recommendations.

I have some thoughts on Newcomb's Paradox. (Of course I am new to this, probably way off base, etc.) I think two boxes is the right way to go, and it seems that intuition towards one-boxing often comes from the idea that your decision somehow changes the contents of the boxes. (No reverse causality is supposed to be assumed, right?) Say that instead of an infallible superintelligence, the story changes to

"You go to visit your friend Ann, and her mom pulls you into the kitchen, where two boxes are sitting on a table. She tells you that box A has either $1 billion or $0, and box B has $1,000. She says you can take both boxes or just A, and that if she predicted you take box B she didn't put anything in A. She has done this to 100 of Anne's friends and has only been wrong for one of them. She is a great predictor because she has been spying on your philosophy class and reading your essays."

Terribly small sample size, but a friend told me this changes his answer from one box to two. As far as I can tell these changes are aesthetic and make the story clearer without changing the philosophy.

And, a question. Why is Bayes so central to this site? I use Bayesian reasoning regularly, but I learned Bayes' Theorem around the time I started thinking seriously about anything, so I'm not clear on what the alternative is. Why do y'all celebrate Bayes, rather than algebra or well-designed experiments?

Edit: Read farther in Thinking, Fast and Slow; question answered.

Welcome to LW.

Also not an expert on Newcomb's Problem, but I'm a one-boxer because I choose to have part of my brain say that I'm a one-boxer, and have that part of my brain influence my behavior if I get in to a Newcomb-like situation. Does that make any sense? Basically, I'm choosing to modify my decision algorithm so I no longer maximize expected value because I think having this other algorithm will get me better results.

0Desrtopa13y

To be properly isomorphic to the Newcomb's problem, the chance of the predictor being wrong should approximate to zero. If I thought that the chance of my friend's mother being wrong approximated to zero, I would of course choose to one-box. If I expected her to be an imperfect predictor who assumed I would behave as if I were in the real Newcomb's problem with a perfect predictor, then I would choose to two-box. In Newcomb's Problem, if you choose on the basis of which choice is consistent with a higher expected return, then you would choose to one-box. You know that your choice doesn't cause the box to be filled, but given the knowledge that whether the money is in the box or not is contingent on a perfect predictor's assessment of whether or not you were likely to one-box, you should assign different probabilities to the box containing the money depending on whether you one-box or two-box. Since your own mental disposition is evidence of whether the money is in the box or not, you can behave as if the contents were determined by your choice.
