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 third incarnation of the welcome thread, the first two of which which now have too many comments to show all at once.)

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.
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 areticle" 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.

Hello everyone!

Thank You for this site and for sharing your thoughts, for genuinely trying to find out what is true. What is less wrong. This has brightened my view of humanity. :)

My name is Lara, I’m from Eastern Europe, 18 years old, currently studying physics, reading a lot and painting in my free time. For about a year and a half now I’ve been atheist; before then- devout and sincere christian, religious nerd of the church. A lot of things in the doctrine bothered me as compltely illogical, unfair and just silly, and somehow I tried to reason it all out, I truly believed, that the real Truth will be with God and that he will help me understand it better. As it turned out, truth seeking and religiosity were incompatible.

Now I’m fairly ‘recovered’- getting used to the new way of thinking about the world, but still care about what is really true and important, worth devouting my life to(fundamentalist upbringing :)). As I still live with my family, it is hard to pretend all the time, knowing they will have no contact with me whatsoever, when I come out; it is really good to find places like this, where people are willing to dig as deep as possible, no matter what, to understand better.

So thanks and sorry for my english. I hope someday I’ll be able to add something useful here and learn much more.

Welcome! Your English is excellent, don't worry on that count.

...also, that's a really tough predicament (hiding your atheism from your fundamentalist family), and I don't have anything wise to say about it, except that it isn't the end of the world when they do find out, and that often people will break their religious commitments rather than really abandon their children (so long as they can think of a religiously acceptable excuse to do so). But I'm not really qualified to give that advice. Hang in there!

I sympathize with you as I'm an atheist with a fundamentalist family who would cut me out of their lives if they found out.

I also envy you, as you had your enlightenment happen at such an early age. I didn't have mine until I was pushing middle age and had created a family of my own...all whom were also fundamentalist. I still live "in the closet" so to speak...

9MichaelVassar10yI'm sorry to hear that your family try to control you like this. Do you expect to physically live near them for long? If not, you may not need to tell them. Surely they have behaviors that they don't tell you about too, and don't honestly expect you to actually act as if you believed (just as they probably don't act that way themselves and expected you to grow out of the confused phase in your life when you were doing all that weird stuff that you did as a result of being a sincere and devout christian who expects things to be logical fair and non-silly once understood)

Thank you all for support, it is incredibly important.

Unfortunately it is a church norm to cut off everyone who leaves, and the doctrine is such that there is no way to be ‘inbetween’. The community is quite closed and one’s whole life is determined- from the way we dress(girls especially), to the way we make carriers (or stay at home and raise children). So in the beginning I decided not to tell anyone at all, knowing how painful it would be for everyone, but after some time I realised that I could not live like that my whole life; though egoistically, after I earn enough money to leave, I will.

9MichaelVassar10yThere are really a lot of possibilities for finding work if you need it, at least if you are a US citizen. I can help you with that if you want. If nothing else,http://lesswrong.com/lw/43m/optimal_employment/ [http://lesswrong.com/lw/43m/optimal_employment/]is available. I bet that if a few LWers could get together to do this (possibly after absorbing some of our West Coast or NYC contingent culture first) and build an amazing community there. email me.
7thomblake10yTo expand on orthonormal's point, note impact bias [http://en.wikipedia.org/wiki/Impact_bias]. If you do end up having to be truthful with them, whatever consequences you're imagining now are probably far worse that what you will actually go through. People tend to carry on just fine. And remember that the virtue of honesty does not require telling all truths, but rather not communicating falsely. If telling your parents you are an atheist will mean to them that you are an amoral person, maybe you should not say so unless that is also true.
4[anonymous]9yHey Lara, being a Slovenian student of physics from a very devout Catholic family (which I actually occasionally still accompany to Sunday mass) I can definitely relate to your story. I coped by sharing my doubts with less religious family members, eventually sharing with my sister that I considered myself atheist. I mostly let my extended family think what they will, but I don't really work to hide my non-belief in any serious way any more. I don't however try to argue with them about it. Mostly because de-converting my family members in a mostly secular country didn't really feel like a top priority, but also because I saw it would be very hard to get them interested in rationality. And without that in my mostly secular country, it didn't really seem worth it since I've come to realize that non-religious delusion is as widespread as religious delusion. I was for a time somewhat conflicted on this, but my general attitude since then is that I love my my family because they are my family not because I think they are good at rational debate or hold true beliefs. I think most parents feel the same way about their children. I'd heartily recommend reading the sequences, since atheism is just the beginning. :) Best wishes, Konkvistador

Hi; I'm a lurker of about one year, and recently decided to stop lurking and create an account.

I'm an undergraduate in Portland-area Oregon. I study mathematics and computer science at Pacific University. I've been interested in rationality for a very long time, but Less Wrong has really provided the formalism necessary to defend certain tactics and strategies of thought over others, which has been very...helpful. :)

Speaking of Portland, it seems that there are many Portland Less-Wrongians and yet there is no meetup. I would like to start a meetup, so I need a bit of Karma to get one started.

Hi, I'm 15, so sadly cannot say much of my education yet, but at least I've read a fair deal. I find the ideas on this site somewhat unappreciated among my age group, but fascinating for me. I've lurked here for close to a year, but I'm irrationally shy of speaking over the internet. I hope to contribute if I find what I think interesting, regardless of my adverseness to commenting. Thank you for the welcome!

8KPier10yThere's an email list and occasional online meetups for LessWrong teenagers; you can join here. [http://groups.google.com/group/lesswrong-highschool/topics?pli=1] Welcome aboard!

Hi everyone! I'm Ozy.

I'm twenty years old, queer, poly, crazy, white, Floridian, an atheist, a utilitarian, and a giant geek. I'm double-majoring in sociology and psychology; my other interests range from classical languages (although I am far from fluent) to guitar (although I suck at it) to Neil Gaiman (I... can't think of a self-deprecating thing to say about my interest in Neil Gaiman). I use zie/zir pronouns, because I identify outside the gender binary; I realize they're clumsy, but English's lack of a good gender-neutral pronoun is not my fault. :)

One of my big interests is the intersection between rationality and social justice. I do think that a lot of the -isms (racism, sexism, ableism, etc.) are rooted in cognitive biases, and that we're not going to be able to eliminate them unless we understand what quirks in the human mind cause them. I blog about masculism (it is like feminism! Except for dudes!) at No Seriously What About Teh Menz; right now it's kind of full of people talking about Nice-Guy-ism, but normally we have a much more diverse front page. I believe that several of the people here read us (hi Nancy! hi Doug! hi Hugh, I like you, when you say I'm wrong you... (read more)

6MBlume10yHi Ozy, it's really good to see you here, I enjoy the blog a lot. I remember reading one of your first social justice 101 posts, finding it peppered with LW links, and thinking "holy crap, somebody's using LW as a resource to get important background information out of the way while talking about something-really-important-that-isn't-itself-rationality -- this is awesome and totally what LW should be for", so that made me happy =)
5MileyCyrus10yHer blog is good. Instead of blindly cheering for a side in the feminism vs men's-rights football game, Ozymandias actually tries to understand the problem and recommend workable solutions.
5_ozymandias10yThank you very much, Miley! I tend to view feminism and men's rights as being inherently complementary: in general, if we make women more free of oppressive gender roles, we will tend to make men more free of oppressive gender roles, and vice versa. However, in the great football game of feminists and men's rights advocates, I'm pretty much on Team Feminism, which is why I get so upset when it's clearly doing things wrong. Also, my pronoun is zie, please. :)

Hi; I've been reading LessWrong for more than a year and a half, now, but I never quite got around to making an account until today.

So, introduction: I'm eighteen years old, female, transgender. I live in California, USA. I don't have a lot of formal education; I chose to be homeschooled as a little kid because my parents were awesome and school wasn't, and due to disability I've not yet entered college.

The road to rationalism was fairly smooth for me. I'm a weirdo in enough ways that I learned early on not to believe things just because everyone else believed them. It took a little bit longer for me to learn not to believe things just because I had always believed them.

I guess my major "Aha!" moment came when I was fourteen, after I finally admitted to myself that I was transgender. I had lied to myself, not to mention everyone else, for almost a decade and a half. I had shied away from the truth every time I'd had the opportunity to see it. And while I'd had pretty good reasons for doing so (Warning: Big-ass PDF), the truth felt better. Not only that, but knowing the truth was better, in measurable ways; it allowed me to begin to move my life in a direction I ac... (read more)

5[anonymous]9yWelcome to the site Kallio! I don't think you are alone in your experience of this. People here are pretty contrarian, metacontrarian even [http://lesswrong.com/lw/2pv/intellectual_hipsters_and_metacontrarianism/]. I hope that in the month since you've posted this you've continued to gain utility from the site. :) While I have long ago read most of them, there are still sequences that I haven't read in a systematic fashion and I don't think I'm that exceptional among long time readers in that regard, so once you feel you've gotten a good grasp on issues don't be afraid to post. Also if you have a question about the material, need a beta reader for a contribution or would just like to discuss stuff with someone, please feel free to PM me. All the best, Konkvistador


I'm a 20 year old student at Georgia Tech, double majoring in Industrial Engineering and Psychology, and am spending the current semester studying abroad at the University of Leeds in the UK.

I read HPMOR this weekend on a bus trip to London and as soon as I returned I found this site and have been enthralled by the Sequences, which I am slowly working my way through.

All of my life I have loved to read and learn new things and think through them, but last year I came to the realization that my curiosity had started to die in my late high school years. I found myself caring about getting a good grade and then abruptly forgetting the information. Much of what I was "learning" I never truly understood and yet I was still getting praise from teachers for my good grades, so I saw no reason to invest more effort. Early last year, I realized that this was happening and attempt to rededicate myself to finding things that again made me passionate about learning. This was a major contribution to adding Psychology as a second major.

This semester of new classes in a new educational system combined with the past few days of reading the Sequences have sparked my interest in man... (read more)

4[anonymous]9yWelcome to the site! Since I suspect you may find it interesting, have you read anything on spaced repetition [http://www.gwern.net/Spaced%20repetition] so far? Also since I'm linking there I just want to warmly recommend gwern's [http://lesswrong.com/user/gwern] site in general, he has a great knack for finding relevant information and presenting it well (good enough to get him a job at the Singularity Institute [http://lesswrong.com/r/discussion/lw/9t8/the_singularity_institute_needs_remote/] !) I've come to know and grown to dislike this feeling in the past few years of university. It is why I spend more effort than needed to try and make knowledge I learn become truly a part of me [http://lesswrong.com/lw/la/truly_part_of_you/]. Of course sometimes you just need to jump through hoops ... Consider asking around for a chavruta [http://lesswrong.com/lw/6j1/find_yourself_a_worthy_opponent_a_chavruta/]. The sequences are loooong (which is good since they are mostly well written) and talking to people about what you read is always fun. Taking up daenerys on her offer also sounds like a good idea indeed. Cheers, Konkvistador
4juliawise9yHi! I also loved finding a place where people were really excited about ideas. You might be interested in 80,000 Hours [http://80000hours.org/], a site on choosing careers that improve the world (and they're very much in favor of making money as a way to do this, though also in favor of education as a career!)

Hi, I’m Brigid. I’ve been reading through the Sequences for a few weeks now, and am just about to start the Quantum Section (about which I am very excited). I found out about this site from an email the SIAI sent out. I’m an Signals Intelligence officer in the Marine Corps and am slated to get out of the military in a few months. I’m not too sure what I am going to do yet though; as gung-ho as I originally was about intel, I’m not sure I want to stay in that specific field. I was a physics and political science major in college, with a minor in women’s studies. I’ve been interested in rationality for a few years now and have thoroughly enjoyed everything I’ve read so far here (including HPMOR) . Also, if there is anyone who is interested in starting a Meetup group in Hawaii (Oahu) let me know!

7Eliezer Yudkowsky9yHi, Brigid! Pleased to have you here! Experience has shown that by far the best way to find out if anyone's interested in starting an LW group is to pick a meeting place, announce a meetup time, and see if anyone shows up - worst-case scenario, you're reading by yourself in a coffeeshop for an hour, and this is not actually all that bad.
5shminux9yWelcome! A warning: while the QM sequence in general is very readable and quite useful for the uninitiated, the many-worlds advocacy is best taken with a mountain of salt. Consider skipping the sequence on the first pass, and returning to it later, after you've covered everything else. It is fairly stand-alone and is not relevant to rationality in general.
8fubarobfusco9yWell, there are a couple of things going on in the QM sequence. One of them is MWI. The other is the general debunking of the commonly-held idea that QM is soooooooo weeeeeeeeird.
7Eliezer Yudkowsky9yA meta-warning: Take shminux's "mountain of salt" advice with an equally large mountain of salt plus one more grain - as will become starkly apparent, there's a reason why the current QM section is written the way it is, it's not meant to be skipped, and it's highly relevant to rationality in general.

How would the Sequences be different, other than in the QM parts, if we lived in a classical universe, or if we had not yet discovered QM?

3[anonymous]9yWild Mass Guessing: in a classical universe, particles are definable individuals. This breaks a whole mess of things; a perfect clone of you is no longer you, and etc.

a perfect clone of you is no longer you

The lack of identity of individual particles is knock down argument against our identities being based on the identities of individual particles. However, if there was identity of individual particals, this does not require that the identity of individual particles contribute to our identities, it would just remove a knock down argument against that idea.

7DanArmak9yNot necessarily. "What/who is you" is a matter of definition to a large extent. If particles have identities (but are still identical to all possible measurements), that doesn't stop me from defining my personhood as rooted in the pattern, and identifying with other sufficiently similar instances of the pattern.
5RichardKennaway9yThat minds are physical processes seems discoverable without knowing why matter is made of atoms and what atoms are made of. That elimination of mentalism seems sufficient to justify the ideas of uploading, destructive cryonics, artificial people, and so on. But I'm actually more interested in what implications there are, if any, for practical rationality here and now. (I will be unmoved by the answer "But FAI is the most practical thing to work on, we'll all die if it's done wrong!!!")

it's not meant to be skipped, and it's highly relevant to rationality in general.

A few people have asserted this, but how is it actually relevant? Is it just a case study, or is there something else there? As RichardKennaway asks, how does QM make a difference to rationality itself?

3ArisKatsaris9ySpeaking from a non-physicist perspective, much of what the QM sequence helped teach me is helping see the world from bottom-up; QM is regular, but it adds up to normality, and it's normality that's weird. Delving down into QM is going up the rabbit's hole away from weirdness and normality, and into mathematical regularity. By analogy, normal people are similarly weird because they're the normality that was produced as the sum of a million years of evolution. Which in turn helps you realize that a random mind plucked out of mindspace is unlikely to have the characteristics we attribute to humanlike normality. Because normality is weird. Once you go from bottom-to-top, you also help dissolve some questions like problems of identity and free will (though I had personally dissolved the supposed contradiction between free will and determinism many years before I encountered LessWrong) -- I still think that many knots people tie themselves over regarding issues like Quantum Suicide or Doomsday Dilemmas, are caused by insufficient application of the bottoms-up principle, or worse yet a half-hearted application thereof.
4DanArmak9yIt's bad enough that we've got people talking about things not being weird, as if weirdness is an objective property rather than something in the mind of the observer. Your words which I quoted are even worse; they're a self-contradiction. If you're not willing to let the word "weird" have its dictionary definition, please, please just taboo it and let the subject die, rather than trying to redefine it as the opposite of the original meaning.
4chaosmosis9yThe commenter was saying "our intuitive understanding of reality" is weird, I think. That's why the commenter was able to noncontradictorily say that Quantum Mechanics fixed some problems and made things less weird.

Hey, I'm -name withheld-, going by Benedict, 18 years old in North Carolina. I was introduced to Less Wrong through HPMoR (which is fantastic) and have recently been reading through the Sequences (still wading through the hard science of the Quantum Physics sequence).

I'm here because I have a real problem- dealing with the consequences of coming out as atheist to a Christian family. For about a year leading up to recent events, I had been trying to reconcile Christian belief with the principles of rationalism, with little success. At one point I settled into an unstable equilibrium of "believing in believing in belief" and "betting" on the truth of religious doctrine to cover the perceived small-but-noteworthy probability of its veracity and the proposed consequences thereof. I'd kept this all secret from my family, putting on a long and convincing act.

This recently fell apart in my mind, and I confronted my dad with a shambling confession and expression of confusion and outrage against Christianity. I'm... kinda really friggin' bad at communicating clearly through spoken dialogue, and although I managed to comport myself well enough in the conversation, my dad... (read more)

my dad is unconvinced that the source of my frustrations is a conflicting belief system so much as a struggle with juvenile doubts.

That is roughly speaking what juvenile doubts are. The "juvenile" mind tackling with conflicts in the relevant socially provided belief system prior to when it 'clicks' that the cool thing to do is to believe that you have resolved your confusion about the 'deep' issue and label it as a juvenile question that you do not have to think about any more now that you are sophisticated.

Next week, from July 30 to August 3, he's going to take me to this big huge realignment thing,

You clearly do not want to go. His forcing you is a hostile act (albeit one he would consider justified) but you are going along with it. From this, and from your age, I infer that he has economic power over you. That is, you live with him or he is otherwise your primary source of economic resources. I will assume here that your Best Alternative To Negotiated Agreement (BATNA) sucks and you have essentially no acceptable alternative to submission to whatever power plays your father uses against you. Regardless of how the religious thing turns out, developing your pot... (read more)

Hi Benedict!

Bad news first: You will not be able to defend yourself. This is not because you're 18, it's not because you can't present your arguments in a spectacular fashion.

It is because noone will care about your arguments, they will wait for the first chance to bring some generic counter-argument, probably centering on how they will be there for you in your time of implied juvenile struggle, further belittling you.

And - how aggravating - this is actually done in part to protect you, to protect the relationship with your dad. With the kind of social capital, pride and identity that's on the line for your father, there is no way he could acknowledge you being right - he'd have to admit to himself that he's a phony in his own eyes, and a failure as a parent and pastor in the eyes of his peers.

To him it may be like you telling him he wasted his life on an imaginary construct, while for you it's about him respecting your intellectual reasoning.

Maybe the rational thing to do is not strive for something that's practically unattainable - being respected as an atheist on the basis of your atheist arguments - but instead focus on keeping the relationship with your parent intact while y... (read more)

9MixedNuts9yGo in panic mode. This conference is not just making a case that Christianity is correct and debating about it. It's bombarding you with arguments for six days, where you won't hear an argument against Christianity or if you do it'll be awkward rude dissent from people in inferior positions, where you won't be able to leave or have time alone to think, and where you're going against your will in the first place. This is time for not losing your mind, not time for changing it. Don't keep an open mind, don't listen to and discuss arguments, don't change your mind because they're right, don't let the atmosphere influence you. If it helps you can think of it as like being undercover among huge patriots and resisting the temptation to defect (and their ideology may be better than yours), or like being in a psychiatrist hospital and watching out for abuse when you know the nurses will try to convince you your reactions are psychiatrist symptoms (and they may well be). So don't see anything at the conference as a social interaction or exchange of ideas. Your goals are to get out of there, to block everything out, to avoid attention, and to watch sharply for anything fishy. Block out the speakers, just watch the audience. If there's a debate be quiet and don't draw attention. If you're asked to speak, voice weak agreement, be vague, or pick peripheral nits. If you're asked to participate in group activities go through the motions as unremarkably as you can. At the socials be a bit distant but mostly your usual self when making small talk, but when someone starts discussing one of the conference topics pretend to listen and agree, smile and nod and say "Yes" and "Go on" and "Oh yeah, I liked that part" a lot. Lie like a rug if you must. Watch the social dynamics and the attitudes of everyone and anything that looks like manipulative behavior. You'll be bored, but don't try to think about any kind of deep topic, even unrelated (doing math and physics problems in your head a
6Vaniver9yHey! I've got a pastor father too, but thankfully my atheism doesn't seem to be a big deal for him. (It helps that I don't live nearby.) I think the "conflicting belief system" is, as I understand it, the right model. There's a Christian worldview, which has some basic assumptions (God exists, the Bible is a useful source for learning about God, etc.), and there's a reductionist worldview, which has some basic assumptions (everything can be reduced to smaller parts, experiments are a useful source for learning about reality, etc.), and the picture you can build out of the reductionist worldview matches the world better than the picture you can build out of the Christian worldview. (There are, of course, other possible worldviews.) I would not put much hope into being able to convince the people at this event that they should be atheists; I wouldn't even hope to convince them that you should be an atheist. And so the question becomes what your goals are. If you're concerned about recanting your atheism and meaning it, the main thing I can think of that might be helpful is the how to change your mind [http://wiki.lesswrong.com/wiki/How_To_Actually_Change_Your_Mind] sequence. You can keep that model in mind and compare the experience you're undergoing to it- it's unlikely that they'll be using rational means of persuasion, and you can point out the difference. Starting a post in discussion is an alright idea; it'll work well if you mention specific arguments that you want to have responses to.
4TimS9yWelcome. I'm sorry that you are in such an awkward situation with you family. In terms of dealing with this conference, I can only echo what MixedNuts said (except for the panicking part). I've always found this quote interesting: We have every reason to think that children's beliefs have no momentum - the evidence is right in front of us, they change their minds so often for such terrible reasons. By contrast, the fact that I disagree with another adult is not particular strong evidence that the other person is wrong. In other words, try to free yourself from feeling obligated to defend anything or feeling guilty for not engaging with those who wish to change your beliefs. You might consider explicitly saying "Social pressure is not evidence that you are right (or wrong)." If the people talking with you assert that they aren't using social pressure, then ask them to stop continuing the debate. Their willingness to leave is a victory for your emotional state, and their refusal is strong evidence that arriving at true beliefs is not really their goal - but the proper reaction to that stance is to leaving the conversation yourself, not try to win the "you are being rude" debate. In short, maximizing your positive emotional state doesn't rely on winning debates. Your goal should be to avoid having them at all. (If you hadn't already read the book your father found, I would have suggested declining to do so).
3OnTheOtherHandle9yI'm not sure how much specific atheist reading you've done, but I found this [http://gretachristina.typepad.com/greta_christinas_weblog/2008/09/the-ten-main-reasons-i-dont-believe-in-god.html] list to be very helpful at articulating and formalizing all those doubts, arguments and wordless convictions that "this makes no sense." This [http://www.ebonmusings.org/atheism/theistguide.html] is also a handy look at what would be truly convincing evidence of the truth of a particular religion's claims. The rest of that author's website is also wonderful.

Several people have alreadt given good answers to your position on infanticide, but they haven't mentioned what is in my opinion the crucial concept involved here: Schelling points.

We are all agreed that is is wrong to kill people (meaning, fully conscious and intelligent beings). We agree that adult humans beings are people (perhaps excluding those in irreversible coma). The law needs to draw a bright line separating those beings which are people, and hence cannot be killed, from those who are not. Given the importance of the "non-killing" rule to a functioning society. this line needs to be clear and intuitive to all. Any line based on some level of brain development does not satisfy this criterion.

There are only two Schelling points, that is obvious, intuitive places to draw the line: conception and birth. Many people support the first one, and the strongest argument for the anti-abortion position is that conception is in fact in many ways a better Schelling point than birth, since being born does not affect the intrinsic nature of the infant. However, among people without a metaphysical commitment to fetus personhood, most agree that the burdens that prohibition of a... (read more)

7Emile10yBut there is no universal agreement on the "age of informed consent", it varies from country to country! And yes, the fact that the limit is arbitrary does undermine its strength; there are often scenarios of "reasonable" sex (in that most people don't consider it as wrong) that would be consider statutory rape or whatnot if the law was taken at the letter. (Also, heck, 10 months is a pretty crappy limit, why not 8 months five days and 42 minutes? 12 months would be much cleaner)
5Alejandro110yPeople disagree about obviousness of such things. For some people, a fetus is obviously a person too. For others, even a mentally deficient adult might not qualify as being obviously a person. Unlike you, I don't expect these disagreements to disappear anytime soon, and they are the reason that the law works better with bright Schelling point lines, if such exist. Age is non-ambiguous, but not non-arbitrary. Re your final objection, I agree that there are cases such as sexual consent where there are no clear Schelling points, and we need arbitrary lines. This does not mean that it is not best to use Schelling points whenever they exist. In the case of sexual consent, the arbitrariness of the line does have some unfortunate effects: for example, since the lines are drawn differently in different jurisdictions, people who move accross jurisdictions and are not epecially well informed might commit a felony without being aware. There are also problems with people not being aware of their partner's age, etc. Such problems are not too big and in any case unavoidable, but consider the following counterfactual: if all teenagers underwent a significant and highly visible discrete biological event at exactly age 16, it would make sense (and be an improvement over current law) to have an universal law using this event as trigger for the age of consent, even if the event had no connection to sexual and mental development and these were continuous. The event would be a Schelling point, such as birth is for personhood.
5Alejandro110yThis is a very good response, that allows us to make our disagreement more precise. I agree that choosing menstruation, or its hypothetical unisex counterpart, is unreasonable because it is too early. I disagree that birth is too early in the same way. Pretty much everyone in our society agrees that 12-year olds cannot meaningfully consent to sex (especially with adults), whereas many believe 6-month old children to be people -- in fact, many believe fetuses to be people! You might say that they are obviously wrong, but the "obviously" is suspicious when so many disagree with you, at the very least for Aumann reasons. To put it in another way: What makes you so certain that birth is so far off from what is reasonable as a line for personhood, when you are willing to draw your line at 10 months? That is much closer to birth than 17 is to 12 years old. Also, I think your analogy needs a bit of amending: the relevant question is, if there was a visible unisex menstruation happening at 17 years old, and an established tradition of taking that as the age of consent, why on earth would a society change the law to make it 16 years and 2 months instead?
7Alejandro110yOne rough effort at such definition would be: "any post-birth member of a species whose adult members are intelligent and conscious", where "birth" can be replaced by an analogous Schelling point in the development in an alien species, or by an arbitrary chosen line at a similar stage of development, if no such Schelling point exists. You might say that this definition is an arbtrary kludge that does not "carve Nature at the joints". My reply would be that ethics is adapted for humans, and does not need to carve Nature at intrinsic joints but at the places that humans find relevant. Your point about different rates of development is well taken, however. I am also not an expert in this topic, so we'll have to let it rest for the moment.

I do think there are some advantages to setting the cutoff point just slightly later than birth, even if by just a few hours:
*evaluations of whether a person should come into existence can rest on surer information when the infant is out of the womb

  • non-maternal reproductive autonomy - under the current legal personhood cutoff, I can count this as an acceptable loss, as I consider maternal bodily autonomy and the interests of the child to be more important, but with infanticide all three can be reconciled
  • psychologically, parents (especially fathers) might feel more buy-in to their status, even if almost none actually end up choosing otherwise, and if infant non-personhood catches on culturally infant deaths very close to births might cause less grief among parents

(All this assumes that late-term abortions are a morally acceptable choice to make in their own right, of course, rather than something which must be legally tolerated to preserve maternal bodily autonomy.)

Infanticide of one's own children should be legal (if done for some reason other than sadism) for up to ten months after birth. Reason: extremely young babies aren't yet people.

I would recommend against expressing this opinion in your OKCupid profile.

Infanticide of one's own children should be legal (if done for some reason other than sadism) for up to ten months after birth. Reason: extremely young babies aren't yet people.

Arbitrary limits like "ten months" don't make for good rules - especially when there's a natural limit that's much more prominent: childbirth.

What exactly counts as "people" is a matter of convention; it's best to settle on edges that are as crisp as possible, to minimize potential disagreement and conflict.

Also "any reason other than sadism", eh? Like "the dog was hungry" would be okay?

4Multiheaded10yEDIT: in the ensuing discussion, we came to an agreement that the psychopathy argument is only true of our present society, and, while strengthening our reasons to keep infanticide illegal right now, wouldn't apply to someplace without a strong revulsion to infanticide in the first place. I've updated my stance and switched to other arguments against infanticide-in-general.

I broadly agree that babies aren't people, but I still think infanticide should be illegal, simply because killing begets insensitivity to killing. I know this has the sound of a slippery slope argument, but there is evidence that desire for sadism in most people is low, and increases as they commit sadistic acts, and that people feel similarly about murder.

From The Better Angels of Our Nature: "Serial killers too carry out their first murder with trepidation, distaste, and in its wake, disappointment: the experience had not been as arousing as it had been in their imaginations. But as time passes and their appetite is rewhetted, they find the next on easier and more gratifying, and then they escalate the cruelty to feed what turns into an addiction."

Similarly, cathartic violence against non-person objects (http://en.wikipedia.org/wiki/Catharsis#Therapeutic_uses) can lead to further aggression in personal interactions.

I don't think we want to encourage or allow killing of anything anywhere near as close to people as babies. The psychological effects on people who kill their own children and on a society that views the killing of babies as good are too potentially terrible. Without actual data, I can say I would never want to live in a society that valued people as little as Sparta did.

5FiftyTwo10yBy what criterion do you consider babies sufficiently "close to people" that this is an issue, but not late term fetuses or adult animals? Specific example, an adult bonobo seems to share more of the morally relevant characteristics of adult humans than a newborn baby but are not afforded the same legal protection.
4[anonymous]10yCan't this same be said of last trimester [http://doctorberlin.com/clients/4289/images/3rd_tri_diagram.jpg] abortions? In any case much like we find pictures or videos of abortion distasteful, I'm sure future baby-killing society would still find videos of baby killings distasteful. We could legislate infanticide needs to be done by professionals away from the eyes of parents and other onlookers to avoid psychological damage. Also forbid media depicting it except for educational purposes.
9wedrifid10yThey're just p-zombies pretending to be people. They only get their soul at 10 months and thereafter are able to detect qualia. I would vote against this law. I'd vote with guns if necessary. Reason: I like babies. Tiny humans are cute and haven't even done anything to deserve death yet (or indicate that they aren't valuable instances of human). I'd prefer you went around murdering adults (adults being the group with the economic, physical and political power to organize defense.)
5Solvent10yWhat do you think of abortion?
9[anonymous]10yOnce we get artificial uteri I think it should be illegal except in cases of rape, but it should be legal to renounce all responsibility for it and put it up for adoption or let the other biological parent finance the babies coming to term. This has the neat and desirable effect of equalizing the position of the biological father and the biological mother.
6gwern10yI have to say, http://lesswrong.com/lw/47k/an_abortion_dialogue/ [http://lesswrong.com/lw/47k/an_abortion_dialogue/] seems relevant to this entire comment tree.
7MileyCyrus10yWhy is sadism worse than indifference? Are we punishing people for their mental states?
4TimS10yOn infanticide, is this a reasonable summary of your position:

Hi everybody,

I’m male, 24, philosophy student and live in Amazon, Brazil. I came across to LessWrong on the zombies sequence, because in the beginning, one of my intelectual interests was analytic philosophy. I saw that reductionism and rationality have the power to respond various questions, righting them to something factually tractable. My goals here is to contribute to the community in a useful form, learn as much as possible, become stronger and save the world reducing the risks of human extintion. I'm looking for some advice in these topics: bayesian epistemology, moral uncertain and the complexity of the wishes. If some of the participants in the forum can help me, I will be very grateful.

4orthonormal10yDo you have specific questions? You could ask them here, or in the comments of the relevant posts (the age of the thread doesn't matter much, since more people read the Recent Comments sidebar than read any particular post's comments). Also, on the topic of morality, have you come across lukeprog's mini-sequence [http://wiki.lesswrong.com/wiki/No-Nonsense_Metaethics]?

Hi all,

I'm 25 from Israel. I worked in programming for 4 years, and have recently decided to move on to more interesting stuff (either math, biology, or neurology, don't know).

I'm new in LW, but have read OB from time to time over over the past 5 years. Several months ago I ran into LW, (re)read a lot of the site, and decided to stick around when I realized how awesome it is.

Nice to meet you all!


5MichaelVassar10yIsrael seems like a natural place for LW. Any thoughts on why the memes haven't gotten more traction there yet?
6erratio10yVery naive guess: people in Israel live in constant high proximity to the two biggest mindkillers, religion and politics/nationalism, both of which have serious and immediate real-world consequences for them.
5FAWS10yNow that you have some karma you should be able to post in the discussion section. Please make sure your post doesn't look like a spam ad, though.
6orthonormal10yTo follow up on what FAWS said, "What are good apps for rationalists?" is a much better title than "Useful Android Apps for the Rational Mind", since the latter sounds like you're trying to sell something to us.

minimalist, 17, white, male, autodidact, atheist, libertarian, california, hacker, studying computer science, reading sequences, intellectual upbringing, 1 year bayesian rationalist, motivation deficient, focusing on skills, was creating something similar to bayesian rationality before conversion, have read hpmor (not intro to lw), interested in contributing to ai research in the future

The Identikit LessWrongian!

"Minimalist" is implied by the sparsity of the rest of the comment, and so is ironically redundant.

There are a few other reasons I could be formatting my introduction that way, such as being bad at English or writing in general. I used "minimalist" both as a heads up for the format and to draw away from the other possible explanations.

I'm sure you're aware at this point, but with that description you blend into the wallpaper.

Thank you for creating a comment to link "stereotypical Less Wrong reader". If only you were a couple of years older.

Since you're 17, have you looked into the week-long summer camp?

Consider restarting with a different account name. Trolling (that is, trying to provoke people) is not welcome here, and when your username is "troll", people will not (and should not) give you the benefit of doubt.

6MarkusRamikin9yThat handle bodes well.

On an elitist gaming forum I used to frequent (RPG Codex), we called such things "post-ironic" (meaning "post-modern as fuck online performance art").

Basically the joke is that everyone gets the joke, and that allows its author to act as if it was no joke, and self-consciously reference that fact - which is the joke.

6Emile9yWelcome to LessWrong! (For a cheap way to give a better impression, you may want to switch to another user name)

Less Wrong,

After lurking for about a week, I decided to register today. I have read some of the Sequences and a good many posts and comments. I am a life long agnostic who recently began to identify as atheist. I am interested in rationality for many reasons, however, my primary reason is that I'd like to learn more about rationality to help me get over my fear of death. A fear that I feel is very irrational, yet I am unable to shake it. I am 39, female and a mother, I have lots of college under my belt but no degree. I guess I never really cared about that. I am also a schizophrenic and that makes rationality quite challenging for me. (Not that it's not challenging for many people.)
I am looking forward to reading more of the Sequences and hope to be able to comment or post in the near future. I am glad I found this site. Thanks for your time.


I've been lurking here on and off since the beginnings at OB, IIRC, though more off than on. Expressed in the language of the recent survey: I'm an 43-year-old married white male with an advanced humanities degree working in the technical side of for-profit IT in the rural USA. I was raised in a non-theist environment and was interested in rationality tools from an early age. I had a spontaneous non-theistic mystical experience when I was 17 that led me to investigate (but ultimately reject) a variety of non-materialist claims. This led to a life-long interest in the workings of the brain, intuition, rationality, bias, and so on.

I enjoy LW primarily because of the interest in conscious self-improvement and brain hacking. I think that the biggest error I see in general among self-described rationalists is the tendency to undervalue experience. My thinking is probably informed most strongly by individual athletics, many of the popular writers in the rationalist tradition, and wide variety of literature. These days, I'm nursing obsessions with Python programming, remote backcountry cycling, and the writing of Rebecca Goldstein.

6orthonormal10yThere are a couple of things you could mean by this. Can you give an example?

There are indeed a couple of different ways I do mean it, but my best specific examples come from athletics. About eight or nine years ago I started getting seriously interested in long distance trail running. Like most enthusiastic autodidacts I started reading lots of material about shoes, clothing, hydration, nutrition, electrolytes, training, and so on. As I'm sure you've seen, a lot of people on the Internet can get paralyzed by analysis in the face of vast easily available information. In particular, they have a lot of trouble sorting out conflicting information gained from other knowledgeable people.

Frequently, further research will help you arrive at less-wrong conclusions. However, in some endeavors there really is a great deal of individual variation, and you just have to engage in lengthy, often-frustrating self-experimentation to figure out what techniques or training methods work best for you. This base of experience can't really be replaced by secondary research. Where research skill comes in, though, is in figuring out where to focus that secondary research (and this in itself is a skill that is honed by experience). As a friend of mine likes to put it: the best prac... (read more)

I'm a 22-year-old mathematics graduate student, moving to Boston next year.

I was recommended HPMoR by another Boston math grad student, followed the authors' notes to read most of the sequences, and then started following lesswrong, although I didn't create an account until recently.

I can't say how I came to actually be a rationalist, though---most of the sequences seemed true or even obvious in hindsight when I first read them, and I've always had a habit of remembering "x tells me y is true" instead of "y is true" when x tells me y is true.

I'm signed up for cryonics. (Current probability estimates 90% that it preserves enough information to be reversible, 95% that I'll die with enough notice to be preserved, 50% that humanity'll advance far enough to reverse it, and 70% that CI'll survive that long.)

I'm vegetarian for carbon efficiency and because the animals that produce most of our meat have negative utility from awful conditions. I don't think sentience is the right standard; is there a good past lesswrong discussion about that?

5orthonormal10yImpressive if true- the best way to test this might be playing a game like The Resistance [http://en.wikipedia.org/wiki/The_Resistance_%28party_game%29]... The last one I remember started off with a really confrontational post, and ended up being an angry discussion; I don't think I'll find and link it. I think you could write a better one, and I'd comment on it- I think your points are good reasons to cut back on meat and to strongly prefer small farms over industrial-scale meat (at least for pork, since pigs are the most sentient of our livestock), and I do both of these, but I don't find it worthwhile to go completely vegetarian.

harmful, unsympathetic psychopaths

There is another, quite different, situation where it happens: Highly stressed mothers of newborns.

The answer to this couldn’t be more clear: humans are very different from macaques. We’re much worse. The anxiety caused by human inequality is unlike anything observed in the natural world. In order to emphasize this point, Robert Sapolsky put all kidding aside and was uncharacteristically grim when describing the affects of human poverty on the incidence of stress-related disease.

"When humans invented poverty," Sapolsky wrote, “they came up with a way of subjugating the low-ranking like nothing ever before seen in the primate world.”

This is clearly seen in studies looking at human inequality and the rates of maternal infanticide. The World Health Organization Report on Violence and Health reported a strong association between global inequality and child abuse, with the largest incidence in communities with “high levels of unemployment and concentrated poverty.” Another international study published by the American Journal of Psychiatry analyzed infanticide data from 17 countries and found an unmistakable “pattern of powerlessness, pov

It's not a rhetorical question, you know. What happens if you try to answer it?

I have a pill in my hand. I'm .99 confident that, if I take it, it will grant me a thousand units of something valuable. (It doesn't matter for our purposes right now what that unit is. We sometimes call it "utilons" around here, just for the sake of convenient reference.) But there's also a .01 chance that it will instead take away ten thousand utilons. What should I do?

It's called reasoning under uncertainty, and humans aren't very good at it naturally. Personally, my instinct is to either say "well, it's almost certain to have a good effect, so I'll take the pill" or "well, it would be really bad if it had a bad effect, so I won't take the pill", and lots of studies show that which of those I say can be influenced by all kinds of things that really have nothing to do with which choice leaves me better off.

One way to approach problems like this is by calculating expected values. Taking the pill gives me a .99 chance of 1000 utilons, and a .01 chance of -10000 utilons; the expected value is therefore .99 1000 - .01 10000 = 990 - 100; the result is positive, so I should ta... (read more)

I heard about LW from a startup co-founder. I'm 22, in Pittsburgh, graduating college in 4 months and on my 2nd startup. Raised hard-core Catholic, and still trying to pull together arguments from various sources as to the existence of God. The posts on LW have certainly helped, and I'd say I'm leaning towards atheism - though it's been a short journey of only 6 months or so since I've started to question my religion.

I'm very interested in the Singularity movement and how that will shape human philosophy and morality. I've also done some body hacking and started tracking my time, an interest which I think a lot of the LW community shares. Looking forward to becoming more active in the community!


The best unsolicited advice I have to give is this: your philosophical leanings are immensely sensitive to psychology, and in particular to the sort of self you want to project to the people around you. So if you want to decide one way or another on a philosophical question that's tormenting you, the biggest key is to surround yourself (socially, in real life) with people who will be pleased if you decide that way. If you want to do your best to figure out what's true, though, the best way is to surround yourself with people who will respect you whatever you decide on that matter, or else to get away from everyone you know for a week or two while you think about it.

Good luck!

Hello LW readers,

Long time lurker here. Just created this account so I can, probably, participated more in LW discussion.

I'm male, 27 years old, from Indonesia. I work as freelance software developer. I love music and watching movies. Any movies. Movie is the only way I can detached from reality and have a dream without a sleep.

I come from Muslim family, both of my parent is Muslim. Long story short, after finished my college, with computer science degree, I tried to learn extend my knowledge more in Islam. I read a lot of books about Islam history, Islam teaching, Quran commentary, book that explain hadith and Quran, etc. Every books that my parents have. Soon, with the help of Internet, I renounce my faith and become an atheist. I see rationalism, philosophy in general, as the way to see the world without giving any judgments. Because, in the end, there is no absolute truth, only facts and opinions.

I know LW from /r/truereddit, and has been reading some of the articles and discussions in here, very informative and thoughtful. The only thing I can help here probably by translating some of articles, especially the Sequences, into Bahasa Indonesia.

Because, in the end, there is no absolute truth, only facts and opinions.

Eliezer's essay The Simple Truth is a nice argument for the opposite. The technical name for his view is correspondence theory. A short summary is "truth is the correspondence between map and territory" or "the sentence 'snow is white' is true if and only if snow is white".

5rv77ax10yActually, The Simple Truth is one of my favorite essay, and it's not the opposite of my statement. Autrey is the one who work with facts (reality) and Mark is the one who work with opinion (belief). Who jump at the cliff at the end ?
6orthonormal10yThere are several different things you could mean by this. Do you agree that, outside of human cognition, some things happen rather than others? And also, isn't it practically useful if our expectations are in line with the sorts of things that actually happen?

Hello! I'm male, 20-something, educator, living in Alberta, Canada. I came across LessWrong via some comments left on a Skepchick article.

My choice to become an educator is founded upon my passion for rational inquiry. I work in the younger grades, where teaching is less about presenting and organizing knowledge and more about the fundamental, formative development of the human brain. Because of this, I am interested in exploring the mental faculties that produce "curiosity behaviors" and the relationship between these behaviors and motivation.

I'm a constructivist at heart; I help guide my students to become masterful thinkers and doers by modifying environmental variables around them. Essentially, I trick them into achieving curriculum-mandated success by 'exploiting' their mental processes. In order to do this effectively, I need to understand as best I can the processes that guide human thoughts and behaviors. This is something I have been interested in since I was young - I am fortunate to have found a career that allows me to explore these interests and use my understanding to better my students'.

I've considered myself to be a rationalist since i was 16 or so, and ... (read more)

6NancyLebovitz10yWelcome! I hope you'll post about some of the specific methods you're used with your students.

Hello Less Wrong!

I am a twenty year old female currently pursuing a degree in programming in Washington State, after deciding that calculus and statistics was infinitely more interesting to me than accounting and economics. I found LW via HPMOR, and tore through the majority of the Sequences in a month. (Now I'm re-reading them much more slowly for better comprehension and hopefully retention.)

I wish to improve my rationality skills, because reading the Sequences showed me that there are a lot of time-wasting arguments out there, and I want to spend my time doing productive, interesting, and fun things instead. Also, I've always enjoyed philosophy, so finding a site that uses scholarship and actual logic to tackle critical issues was amazing.

Other defining things about me: I like cooking, folding origami, playing video games, and reading science fiction, fantasy, and history books. I struggle with procrastination and akrasia. I look forward to self-improvement!


tl;dr This seems like a place that I can use to shore up some of my cognitive shortcomings, eliminate some bias and expand my worldview. Maybe I can help someone else along the way.

I have been reading the material here for the last several days and have decided that this is a community that I would like to be a part of and hopefully contribute to. My greatest interests are improving my map of the territory(how great is that analogy?), using my constantly improving map to be a better husband and father, and exploring transhumanist ideas and conceits.

I came to be a rationalist when I started reading somewhat milquetoast skeptical literature. Having been raised religious and having served in the Marine Corps I have found that I have a tendency to allow arguments from authority too much credence. If I am not careful I can serve as quite the dutiful drone.

It became important over the last few months that I be able to do as much of my own philosophical and scientific legwork as possible. If an author or speaker that I enjoy espouses ideas I am inclined to agree with it is vital (in my estimation) that I either be able to verify the information presented myself or locate reliable...

4TimS9yWelcome to LessWrong. One of the most interesting parts of LessWrong for me is noticing the cognitive bias in our thought process. For example, noticing that one dislikes another solely because the other is a member of a different group. (Psychology calls this the in-group bias [http://lesswrong.com/lw/lt/the_robbers_cave_experiment/]). Noticing those sorts of mistakes doesn't necessarily require all that much mathematical ability. In short, the hope in this community is that clear thinking helps you achieve your stated goals (rather than some inaccurate approximation created by unclear thinking from the imperfect brain). In short, don't sweat the math, there's lots of practical stuff that can be achieved without it. If you are particularly interested in improving your self-awareness, might I recommend Alicorn's Luminosity [http://lesswrong.com/lw/1xh/living_luminously/] sequence?

Hello there!

I think I first saw LessWrong about three years ago, as it frequently came up in discussions on KW, the forum formerly linked to the Dresden Codak comic. This makes mine one of the longer lurking periods, but I've never really felt the urge to take discussion to the actual posts being discussed and talked about them elsewhere when I felt the need to comment. All this changed when Alicorn told me that when I was asked to make a post relevant to LessWrong that meant I actually had to post it on LessWrong (a revelation which I should have probably anticipated). So it has come to this.

The simplest place to start describing myself is by saying that I'm the type of person that skims through the 200 most recent comments to see which ones are well liked before writing anything.* In real life terms, I've finished up my bachelor's degree in December, after making various errors. Unfortunately, with it finished, I have discovered that I lack motivation to pursue a standard career, since just about the only things I find myself caring about are stories, knowing the future (in the general, not the personal, respect), and understanding things, particularly things related to people.

Infanticide has been considered a normal practice in a lot of cultures. The Greeks and Romans, for example, don't seem to have been run down by psychopaths.

I don't think we have a good way to know about the later harmful actions of people who kill their infants. Either we find them out and lock them up, in which case their life is no longer really representative of the population, or we don't know about what they've done.

4Multiheaded10yI've managed to overlook the most important (and fairly obvious) thing, though! If the idea of "childkilling=bad" is weakly or not at all ingrained in a culture, it's easy to override both one's innate and cultural barriers to kill your child, so most normally wired people would be capable of it => the majority of childkillers are normal people. If it's ingrained as strongly as in the West today, there would be few people capable of overriding such a strong cultural barrier, => the majority of childkillers left would be the ones who get no barriers in the first place, i.e. largely harmful, unsympathetic psychopaths. The other ones would have an abnormally strong will to override barriers and self-modify, which can easily make them just as dangerous.

Okay, got it. I agree that in a culture that condemns infanticide, people who do it anyway are likely to be quite different from the people who don't. But Bakkot's claim was that our culture should allow it, which should not be expected to increase the number of psychopaths.

I'm also not sure that unbounded social stigma is an effective way to deter people who essentially don't care about other people. We don't really know of good ways to change psychopathy.

Hello all.

I've been lurking around here and devouring the sequences for about two years now. I haven't said much because I rarely feel like I have much that's useful, or I don't feel knowledgeable about the subject. But I thought I might start commenting a bit more.

I'm 19, in Florida and studying engineering. I really want to do something that will bring the world forward in some way, and right now that has me pointed at trying to put my personal effort towards nanotechnology. For now though I'm just trying to win classes and learn as much as I can.

Not too much more than 'hi', but there it is.

Hello everyone,

My name is Isti, I am from Indonesia and I have been a lurker for this site for almost to years now. I came across this website when I was learning about skepticism and I just could't stop. I was afraid to join because of my limited English and I always think that this is not newbie friendly. Maybe I was wrong.

I am an atheist, and it's not an easy to be atheist in Indonesia. If you're not familiar with Indonesia, it's considered against the law to be an atheist and the religious extremist keeps growing. A man was sent to jail few years ago because he posted an atheism related status on his Facebook. He was charged with religious blasphemy. I only told my close friends about it (and to strangers on the internet).

I just want to say I am so glad to finally find courage to sign up and say something in this website. I hope I can contribute more than just introduction in the future.

4Kawoomba8ySo are we! Happy to have you along for the ride!


I'm a mathematician and working as a programmer in Berlin, Germany. I read HPMOR after following a recommendation in a talk on Cognitive Psychology For Hackers and proceeded to read most of the sequences.

Reading LW has had several practical consequences for me: Spaced repetition and effective altruism were new to me. Things have also improved around social skills, exercise and nutrition.

I'm also part of a small Berlin LW meetup: spuckblase and me have met twice - and now we got contacted by two other Berlin based lurkers which prompted the creation of a wiki entry and a mailing list. We're now planning the first meetup that will actually get a meetup post and be announced in advance.

Hi there. I'm Hermione (yes, really). I went to my first LW meetup recently and I'm now working on the Rationality Curriculum, so it feels like time to introduce myself and start getting involved in discussions.

There are a lot of things I'd be interested in talking about. I only found LW a couple of months ago so I'm trying to level up in rationality and work out how to teach others to do so at the same time. I'll probably be posting about this and asking for advice. Has anyone written about their experiences of reading the sequences for the first time? Should I try and absorb things really quickly, or is it better to take it slowly, and if so, what comes first? That kind of thing.

I've also been inspired by Alicorn's Luminosity sequence and have been piloting a beeper experiment, Mihaly Csikszentmihalyi style. In order to understand myself and my moods better, I've been recording what I'm doing and how I feel at random times (3x/day). I'd like to improve the indicators I've been using. I struggle to get the right balance between quantitative (more analysable) and qualitative (more accurate). Any suggestions?

Finally, I'd really like to meet some more rationalists in person, so please PM me if you're in Brussels!

Hi people :) I'm 16 from France and the Philippines, going to a Christian boarding school. Um, i met a guy on Omegle... he gave me a link to this website after a conversation about Christianity. Long story short, I'm confused. Maybe someone would like to help me get my head straight?

8Baughn10ySure~! Though for a starter, what in particular are you confused about? You might want to start by skimming Making Beliefs Pay Rent [http://lesswrong.com/lw/i3/making_beliefs_pay_rent_in_anticipated_experiences/] and Belief in Belief [http://lesswrong.com/lw/i4/belief_in_belief/], which lacking evidence to the contrary I believe are most likely to be helpful.

Hello LW community, my name is Karl, but please call me MHD for short; here's a lot of sentences beginning with "I..." :

I am a 19 year old, slightly gifted individual, male of gender and psyche, bi, hard to define my preferred relationship structure; honestly my gonads and sexual preference are mostly irrelevant here.

I came here by way of HPMoR and was pressed to do some serious reading by my good friend, known around here as Armok_GoB.

I have at time of writing read sequences MaT and MAtMQ along with some non-structured link-walking, looking to read Reductionism next. My attitude is so far positive, but I read it with a healthy dose of sceptic afterthought and note-taking to verify that it really does make sense. You see, my native language is not English, and I have read a study that one is more gullible when communicating in a non-native language.

My mind is built for logical thinking and I have a knack for mathematics, physics and language. I know approx. 12 turing complete programming languages (C likes, LISPs, ML family, SmallTalk-esque, Assembly) reasonably well. I am looking into Tensors, Bayesian probability, formal logic, type theory, quantum physics, relativity, ... (read more)

I am not a fan of cryonics because I know that freezing, regardless of method, is a very good way to destroy tissue

Cryonics uses vitrification, which protects from the tissue-destroying crystal formation.

8Kaj_Sotala10yThis seems needlessly confrontational, especially as a comment to a newcomer.
5Vaniver10yWelcome! Was the study in a non-native language? ;)

Hi all, I'm a lurker of about two years and have been wanting to contribute here and there - so here I am. I specialize in ethics and have further interests in epistemology and the philosophy of mind.

LessWrong is (by far) the best web resource on step-by-step rationality. I've been referring all aspiring rationalists to this blog as well as all the people who urgently need some rationality training (and who aren't totally lost). So thanks, you're doing an awesome job with this rationality dojo!

Salutations and whatnot! My name is Joyce, I'm a high school sophomore. Probably on the younger side of the age spectrum here, but I don't mind starting young. The idea of rationality isn't new to me, I've always been more inclined to the "truth", even when it sometimes hurts. In my mind knowing more about the truth = better person, so that's my motivation for being here. I'm have better grades than the average, but for the past couple of years the thing I hated most about myself was the fact that I usually "coast" a class, get my A, and then promptly forget everything I've done in the class. My goal was "get an A", not "learn something new". I'd like to learn new things now, and actually retain it, instead of just coasting by. Knowledge is power. I want to be the best, like no one ever was.

Um. When I was younger, perhaps ten, while I was tinkering with Photoshop, my older cousin approached to me and tried to introduce to me the idea of fallacies. He's...nine years older than me, so he was a barely an adult. I forgot most of the conversation, but from what I DO remember, blaming a stomachache on the last thing you ate was falling prey to SOME... (read more)

6Vladimir_Nesov9yThis is actually one danger of learning about fallacies: you become more able at defeating arguments, and this holds irrespective of their truth, so if you have a standard tendency to privilege arguments for the positions you already hold, that makes it harder for you to change your mind. See the post Knowing About Biases Can Hurt People [http://lesswrong.com/lw/he/knowing_about_biases_can_hurt_people/].

Hello, Less Wrong.

Like some others, I eventually found this site after being directed by fellow nerds to HPMOR. I've been working haphazardly through the Sequences (getting neck-deep in cognitive science and philosophy before even getting past the preliminaries for quantum physics, and loving every bit of it).

I can't point to a clear "aha!" moment when I decided to pursue the LW definition of rationality. I always remember being highly intelligent and interested in Science, but it's hard for me to model how my brain actually processed information that long ago. Before high school (at the earliest), I was probably just as irrational as everyone else, only with bigger guns.

Sometime during college (B.S. in mechanical engineering), I can recall beginning an active effort to consider as many sides of an issue as possible. This was motivated less from a quest for scientific truth and more from a tendency to get into political discussions. Having been raised by parents who were fairly traditional American conservatives, I quickly found myself becoming some kind of libertarian. This seems to be a common occurrence, both in the welcome comments I've read here and elsewhere. I can'... (read more)

4DSimon10yWelcome to LW! I like the "just with bigger guns" metaphor a lot; the trouble with intelligence is its ability to produce smart-seeming arguments for nearly any silly idea.

Hi, I'm Nick Bone ... Just joined the site.

I'm based in the UK and interested in a wide variety of topics in science and associated philosophy. In particular, the basics of rationality (deductive and inductive logic, Bayesian Theorem, decision theory), foundations of mathematics (logic and set theory). Plus some of the old staples (classical arguments for/against existence of God, first cause, design, evil and so on).

My background is in mathematics and computer science (PhD in maths) and I'm currently working in an area of applied game theory. Generally I found the site by Googling, and the quality of discussion seems rather higher than on other discussion boards. Hope I can contribute.

By the way, I started off by putting together some thoughts on the "Doomsday Argument" and Strong Self-Selection Assumption which I hadn't seen discussed before. Since I'm brand new, and have no karma points, I'm not sure where to post them. Any suggestions?

Common reasons I downvote with no comment: I think the mistake is obvious to most readers (or already mentioned) and there's little to be gained from teaching the author. I think there's little insight and much noise - length, unpleasant style, politically disagreeable implications that would be tedious to pick apart (especially in tone rather than content). I judge that jerkishness is impairing comprehension; cutting out the courtesies and using strong words may be defensible, but using insults where explanations would do isn't.

On the "just a-holes" note (yes, I thought "Is this about me?"): It might be that your threshold for acceptable niceness is unusually high. We have traditions of bluntness and flaw-hunting (mostly from hackers, who correctly consider niceness noise when discussing bugs in X), so we ended up rather mean on average, and very tolerant of meanness. People who want LW to be nicer usually do it by being especially nice, not by especially punishing meanness. I notice you're on my list of people I should be exceptionally nice to, but not on my list of exceptionally nice people, which is a bad thing if you love Postel's law. (Which, by Postel's law, nobody but me has to.) The only LessWronger I think is an asshole is wedrifid, and I think this is one of his good traits.


So, am I a second-class citizen because I found this place via MoR?

Anyways, I've been Homeschooled for the majority of my education thus far, mostly due to my Creationist parents' concerns about government-run schools. Fortunately they didn't think to censor the internet, and here I am. My PSATs showed me in the 98th percentile, so I expect I'll be able to get into a decent university. Plan A has always been Engineering, but after going through a few of the more inspirational sequences I think I may readjust my plans and try to do some good for this planet. How does one get into the Singularity business?

7thomblake10yI'm pretty sure that accounts for most of our new readership over the last year or so. ETA: To actually answer the question, no. I'm pretty sure the preferred method here currently is #1 below, but here are some options: 1. Make lots of money doing something else and then give it to SIAI. 2. The lukeprog method: Be insanely awesome at scholarship and get tens of thousands of Lw karma in a few months and be generally brilliant and become a visiting fellow and wow everyone at SIAI. 3. Go start your own Singularity. With blackjack. And hookers. Also, I'm generally of the opinion that having been suddenly inspired by something you read recently should be evidence against that thing being what you should do with your life (assuming your prior is based on your feelings about it). You should check out some of the material by Anna Salamon on how to take that kind of decision seriously (I don't have a useful link handy).
4NancyLebovitz10yWith great difficulty. And it's not clear whether there will be any repeat trade.


I'm a 26 year old guy from the UK. I've finished writing my Ph.D. thesis in "Quantification of risk in large scale wind power integration" and I'm now working as a phone-app framework developer. I spent the last year on a round the world travel where I have spent a lot of my time writing practical philosophy. After coming back I found this site and read the core sequences. I loved them, they echoed a lot of my previous thoughts then took them much further. I felt like they would be easier to understand if they were one article so I have been re-writing bits of them for my own benefit. I am in two minds whether to post them here but I would appreciate the feedback to see if I have understood what was written.

4fburnaby10yI'd love to see them when they're somewhere approaching done.

Thanks to Emile for suggesting I come here write something. I hope to get to the New York meetup on Sunday; I'm not ready for "rituals" and futuristic music just yet.

I just ran across LW by trying google terms along the lines of memetics "belief systems", etc., which led me to some books from late 90s like "Virus of the Mind", and in the last 2-3 years some just "OK" books on religions as virus-like meme systems. This kind of search to see what people may have said about some odd combination of thoughts that I suspect might be fruitful has brought me interesting results in the past. E.g. by googling ontological comedian, I discovered Ricky Gervais which has brightened my life (his movie "The Invention of Lying" out to be of interest to LW-ers). I'm interested in practical social epistemology -- trying to come up with creative responses to what looks like major chunks of the population (those pesky folks who elect presidents) being less and less moored in reality and going off into diverse fantasy lands -- or to put it another way, a massive breakdown in common sense about what sources are reliable.

Hello, everyone. I'm Lykos, and it's a pleasure to finally be posting here. I'm a high school junior and I pretty much discovered the concept of rationality through HP:MoR. I'm not sure where I discovered THAT. I'm an aspiring author, and am always eager to learn more, and rationality, I've found, has helped me with my ideas, both for stories and in general. I've currently read the Map and Territory sequence, and am going through Mysterious Answers to Mysterious Questions. I doubt I'll be posting much- I'll probably be spending most of my time basking in the intelligence of the rest of you.

Either way, it is a pleasure to join the community. Thank you.


I've been occasionally reading for a while, and have decided to get a login. I suppose the reason I'm here is that it's become important in the last 2 years or so that my beliefs are as accurate as possible. I've slowly had to let go of some beliefs because the evidence didn't seem to support them, and while that's been painful it has been worthwhile.

I'm also a friend of ciphergoth's - we've discussed less wrong a lot! I don't feel like I know a great deal yet - I still need to read more of the sequences, so I'll stick to asking questions until I feel I know more :-).

I'm 28, female, and I live in Cambridge, UK. My academic background is in the philosophy/politics/economics area, and I work in accounts.


Could you clarify this point a little?


The Internet is full of people who seem to have as one of their primary goals to expound their chosen tribe's political affiliation and defend it against all opposition, even in spaces predominantly dedicated to something else.

If LessWrong becomes a place where local norms allow discussion of the nominal rationality of Libertarianism, or Liberalism, or Conservatism, or whatever, and contrasting it with the demonstrable irrationality of other political ideologies, I expect that a subset of those people will devote significant resources to expounding their chosen tribe's political affiliation and defend it against one another, taking care to from time to time intone the magic formulas "it would be rational to" and "that's not rational" to mask, perhaps even from themselves, the reality of what was going on.

I'd find LW a less useful community were that to happen. I suspect I'm not alone.

I though the primary goals of LW include refining and promoting human rationality, and I see no reason why this goal would not apply to politics.

Can you clarify this point a little? I don't see where I'm suggesting that this goal doesn't apply to politics. What I'm saying is I'm skeptical that a public internet group like LW can achieve this goal as applied to politics.

The primary goal of the present LessWrong community is to refine and promote human rationality. The primary goal of people who would register to join political conversations on LessWrong is liable to be different.

4witzvo9yTastefully left unsaid, is that giving people interested in political conversations an incentive to join Less Wrong could erode the quality of discussion. This is an important point. However, another important point is that maybe it's really important to the betterment of the world that there be a place on the internet, another site perhaps, where it is appropriate to discuss policy, but where the merits of the argument, and the accuracy of facts are of paramount importance. Such a site wouldn't be perfect, but surely it could be an improvement over what I've seen on the internet. Such a site could borrow from the scoring mechanisms that have worked on this site, but would need significant refinement. For example, any post which engaged is demagoguery would need to lead to severe chastisement. Another refinement would be tools that help to break an argument down. E.g. to decide which sentences in a post are factually accurate, and which sentences are fallacious ( mockup [http://infobeautiful2.s3.amazonaws.com/RhetoricalFallacy_SameSexMarriage.png]). Additionally, since you can't talk about policy without treading on normative issues ("equality of opportunity is more important than helping out the disadvantaged" or "human rights are more important than animal rights") the site would need to find a way to carve these issues out of the discussion; not ignore them, just find a way to lay them succinctly to the side (I don't know how). Personally, I think the most important issue in politics is how to reform politics. I.e. how to ensure that our institutions function for "the common good" by making changes to rules/practices so that individual self-interest is channeled toward what's good for the group. I think this is a sound principle that can inform but not decide many issues. Maybe building a website in which reasonably rational policy choices are made could be a first step toward reforming our political institutions.

I'm very excited to have found this community. In a way, it's like meeting a future, more evolved version of myself. So many things that I've read about here I've considered before, but often in a more shallow and immature way. A big thanks to all of you for that!

To the topic of me, I'm 24, male, and Swedish. After studying some of PJ Eby's work, I identify strongly as a naturally struggling person. I've been trying to figure out why for all my life, I think I read Wayne Dyer at about the same age as Eliezer read Feynman. Since then I've read a lot more, and at this point it seems like I have very credible explanations for why things turned out as they did.

Still, even though I might think I ought to have the tools now to stake out a better future path for myself, I'm plagued by learned helplessness and surrounded by ugh-fields. But as I see it there is only one best way forward - to learn more and then attempt to do things better.

I'm a great admirer of the stoic philosopher Lucius Seneca. Here's a short segment from one of his letters that resonates with me:

It is clear to you, I know, Lucilius, that no one can lead a happy life, or even one that is bearable, without the pursuit o

19 male, currently in Florida.

Used to be a hardcore Christian. Then I started looking for alternate explanations and wound up believing in magic because I wanted it to be real. Then I read HP:MoR and it changed my life. My head is on a lot straighter now.

At first I thought this was just something cool. Then I was talking to someone about investing a fairly large amount of money. As we were talking, I was conscious of myself changing my plans to agree with him simply because he was nice. Despite this, he still changed my mind even though I recognized that he did it by being nice instead of a good argument. Had to go home before I could think clearly again.

It scared me that I could be so easily swayed by the Dark Arts, as I've heard them referred to. This might be something worth taking seriously after all.

So now I'm about to use what I learned to buy a car. A year ago, I would've just gone down with an informed friend and pick up something functional. Now I'm going down with a friend and a journal, identifying several possible vehicles and taking notes, then spend a week doing research on price, making sure I'm not being swayed by the salesman being nice, etc. before I actually spend any money.

I look forward to becoming less wrong.

If "hunting down" psychopaths is our goal, we'd do better to look for people who torture or kill animals. My understanding is that these behaviors are a common warning sign of antisocial personality disorder, and I'm sure it's more common than infanticide because it's less punished. Would you advocate punishing anyone diagnosed with antisocial personality right away, or would you want to wait until they actually committed a crime?

I'd put taboos in three categories. Some taboos (e.g. against women wearing trousers, profanity, homosexuality, or atheism) seem pointless and we were right to relax them. Some taboos, like those against theft and murder, I agree we should hold in place because they produce so little value for the harm they produce. Some, like extramarital sex and abortion, are more ambiguous. They probably allow some people to get away with unnecessary cruelty. But because the the personal freedom they create, I think they produce a net good.

I put legalized infanticide in the third category. I gather you put it in the second? In other words, do you believe the harm it would create from psychopaths killing babies and generally being harder to detect would be greater than the benefit to people who don't raise unwanted children?

Also, thank your for reminding me that I have to sharpen my posting abilities.

Vladimir Nesov made a very true counterargument, you endorsed it to test my ability to change my standpoint. Nothing wrong with that; and lo and behold, I actually have. Congratulations, you and Vladimir_Nesov both get an upvote from the new guy.

Hello, I'm 16 years old and from the UK. I found this blog via MoR and I'vebeen lurking for a few months now (this is my first post I think), and I'm slowly but surely working my way through the sequences. I think I've gotten to the point where I can identify a lot of the biases and irrational thoughts as they form in my brain, but unfortunately I'm not well-versed enough in rationality to know how to tackle them properly yet.

Greetings, everyone. My name is Elizabeth, and I am a young adult female beginning to learn how to think for herself. I stumbled across this website right after reading Alicorn's fanfiction Luminosity in the summer of 2010. Due to some personal issues, life in general, and a dead hard drive, I stopped visiting Less Wrong up until a couple of weeks ago.

I found Less Wrong attractive because of its being a free resource on learning the art of rationality. Borderline Personality Disorder runs in my family, and so my hypothesis is that I personally am drawn to things like LW partly in order to "self-medicate" after years of chaos, unpredictability, and irrationality. Chances are likely that I will be very quiet on this website for several months at least: for one thing, that is my usual modis operandi when learning about and researching a topic; for another, it would seem that I need to thoroughly acquaint myself with the sequences and other such work in order to fully understand and be able to contribute to more recent posts/discussions.

Hi y'all. I'm a senior in high school in the Silicon Valley who's been lurking for a couple of months. I've been working my way through the Sequences since then. I don't know how much I have to contribute to the discussion, since I'm a bit of a newcomer to rationalism, but I enjoy reading everyone else's discussions.

I was introduced to this site through my philosophy class- a research project on transhumanism led me to Eliezer Yudkowsky's site, which led me to here. I came here for the Sequences, stayed here for the intelligent discussion (just like almost everyone else on this page). I'm really interested in computer science and economics and how they intersect with rationality.

5orthonormal10yWelcome! Cool! Was this an assigned topic or a self-chosen one? And since you're a HS senior, you might find it worthwhile to read the threads on where [http://lesswrong.com/lw/4r3/college_selection_advice/] (or even whether [http://lesswrong.com/r/discussion/lw/34d/advice_for_a_budding_rationalist/]) to go for college next year, or start your own thread if you want personalized advice.

I'm afraid you may have your bottom line written already. In the age of ultrasound and computer generated images or even better in the future age of transhuman sensory enhancement or fetuses being grown outside the human body the exact same argument can be used against abortion.

Especially once you remember the original context was a 10 month old baby, not say a 10 year old child.

7Multiheaded10yThen I might well have to use it against abortion at some point, for the same reason: we should forbid people from overriding this part of their instincts.

Hi everyone,

A few of you have met me on Omegle. I finally signed up and made an account here like you guys suggested.

About me: I'm 26 years old, and my hobbies include creative writing and PC games. My favorite TV show is Rupaul's Drag Race.

I think I share almost all of the main positions that people tend to have in this community. But I actually find disagreements more interesting, so that's mainly what I'm here for. One of my passions in life is debating. I did debate team and that sort of thing when I was younger, but now I'm more interested in how to seriously persuade people, not just debating for show. I still have a lot of improving to do, though. If anyone wants to exchange notes or get some tips, then let me know.



4MugaSofer8yI'm going to be the first person to point out that your objective should be to come to the correct conclusion, not to persuade people, because if you can out-argue anyone who disagrees with you you'll never change your mind, and "not every change is an improvement, but every improvement is a change". With that noted, persuasion is a useful skill, especially if you're more rational than the average bear. Cryonics, for example, is a good low-hanging fruit if you can just get people to sign up for it.
3orthonormal8yHi Flora! Re: debating and persuading, the reflexes you developed for convincing third parties to a debate can actually be counterproductive to persuading the person you're speaking with. For example, reciprocity [http://en.wikipedia.org/wiki/Reciprocity_(social_psychology\]) can really help: the person you're talking with is much more likely to really listen and consider your points if you've openly ceded them a point first. Practicing this has the nice side effect of making you pay more attention to their arguments and interpret them more charitably, increasing the chance that you learn something from your conversational partner in the process.


My name is John Paton. I'm an Operations Research and Psychology major at Cornell University. I'm very interested in learning about how to improve the quality of my thinking.

Honestly, I think that a lot of my thoughts about how the world works are muddled at the moment. Perhaps this is normal and will never go away, but I want to at least try and decrease it.

At first glance, this community looks awesome! The thinking seems very high quality, and I certainly want to contribute to the discussion here.

I also write at my own blog, optimizethyself.com

See you in the discussion!


"Something very powerful and supernatural* exists, doesn't seem to be hostile, and doesn't mind that I call it the Christian God."

For what it's worth, I'm .9+ confident of the following claims:
1) there exist phenomena in the universe that "human science" (1) doesn't commonly accept.
2) for any such phenomenon X, X doesn't mind that you call it the Christian God
3) for any such phenomenon X, X doesn't mind that you call it a figment of your imagination
4) for any such phenomenon X, X is not "hostile" (2) to humans

So it seems we agree on that much.
Indeed, I find it likely that most people on this site would agree on that much.

the amount of evidence that there is something supernatural* if far greater than the amount of evidence that there are millions of people lying about their experiences.

As above, I think the evidence supporting the idea that there exist phenomena in the universe that "human science" (1) doesn't commonly accept is pretty strong. The evidence supporting the idea that people lie about their experiences, confabulate their experiences, and have experiences that don't map to events outside their own brains despite seeming to,...

I am a nearly seventeen year old female in the US who was linked by a friend to The Quantum Physics Series on LessWrong after trying to understand whether or not determinism is /actually/ refuted by Quantum Mechanics. I am an atheist, I suppose.

This all began as a fascination with science because I thought it would permit me to attain ultimate knowledge, or ultimate understanding and thus control of "matter". Later, I became fascinated with nihilism and philosophy, in search of defining "objectivity". It took off from there and now I am currently concerned with consciousness and usage of artificial intelligence to transfer our biological intelligence to a more effective physical manifestation.

I'm a little scared, naturally, because I think this would change a lot of what we currently understand as humans. As Mitchell Heisman describes, there exists a relationship between the scientist and the science. If the scientist is changed, I would think that the science, or knowledge, would in itself change. Some questions I have ATM: "Does objectivity exist? Can it be created? Can the notion or belief or idea of objectivity be destroyed? Will intelligence bec... (read more)

Hello people, 49 year old father of 4 sons, 17-27, eldest of 9,i come from a background of mormonism, my parents having been converted when i was 3.

So my reality was the dissonance of mormon dogma and theology vs what i was being 'taught' at school,vs what i experience for my self.

Now, having been through the divorce of my parents(gross hypocrisy if you're a mormon) the suicide of my brother and my own divorce,also finding myself saying i would die/kill for my beliefs,i began to realise what a mess i was and started asking questions,leaving the church (demonstrating with placards every sunday for 2 years) in 1996.

So i found myself wanting and needing a new philosophy! I'm particularly interested in learning how to 'be less wrong'! I'm still looking around and am currently interested in the non aggression principle.

I look forward to learning the tools i see here,so that i may make more considered choices.I recognise i'm a clumsy communicator and probably i'm somewhat retarded in comparison to a lot of you. Anyway i look forward to watching and learning,maybe even contributing one day! Tim.


I'm 18, an undergraduate at University of Virginia, pre-law, and found you through HPMOR.

Rationality has been a part of me for almost as long as I can remember, but for various reasons, I'm only recently starting to refine and formalize my views of the world. It is heartening to find others who know the frustration of dealing with people who are unwilling to listen to logic. I've found that it is difficult to become any better at argument and persuasion when you have a reputation as an intelligent person and can convince anyone of anything by merely stating it with a sufficiently straight face.

More than anything else, I hope to become here a person who is a little less wrong than when I came.

This "intelligent reputation" discussion is interesting.

I had kind of an odd situation as a kid growing up. I went to a supposedly excellent Silicon Valley area elementary school and was generally one of the smartest 2-4 kids in my class. But I didn't think of myself as being very smart: I brushed off all the praise I got from teachers (because the villains and buffoons in the fiction I read were all arrogant, and I was afraid of becoming arrogant myself). Additionally, my younger brother is a good bit smarter than me, which was obvious even at that age. So I never strongly identified as being "smart".

When I was older I attended a supposedly elite university. At first I thought there was no way I would get in, but when I was accepted and got in I was astonished by how stupid and intellectually incurious everyone was. I only found one guy in my entire dorm building who actually seemed to like thinking about science/math/etc. for its own sake. At first I thought that the university admissions department was doing a terrible job, but I gradually came to realize that the world was just way stupider than I thought it was, and assuming that I was anything close to normal was not an accurate model. (Which sounds really arrogant; I'm almost afraid to type that.)

I wonder how else being raised among those who are smarter/stupider than you impacts someone's intellectual development?

7[anonymous]9yOr even without a straight face. Sometimes I've made wild guesses (essentially thinking aloud) and, no matter how many “I think”, “may”, “possibly” etc. I throw in, someone who has heard that I'm a smart guy will take whatever I've said as word of God.
4Petra9yYes. My personal favorite was in middle school, when I tried to dispel my assigned and fallacious moniker of "human calculator" by asking someone to pose an arithmetic question and then race me with a calculator. With a classroom full of students as witnesses, I lost by a significant margin, and not only saw no lessening of the usage of said nickname, but in fact heard no repeating of the story outside of that class, that day.
9DaFranker9yBeware indeed of giving others more bouncy walls on which evidence can re-bounce and double-, triple-, quatruple-, nay, Npple-count! I once naively thought to improve others' critical thinking by boosting their ability to appraise the quality of my own reasoning. Lo' and behold, for each example I gave of a bad reasoning I had made or was making, each of them was inevitably using this as further evidence that I was right, because not only had I been right much more than not (counting hits and arguments are soldiers and all that), but the very fact that I was aware of any mistakes I was making proved that I could not make mistakes, for I would otherwise notice mistakes and thus correct myself. TL;DR: This remains a profoundly important unsolved problem in large-scale distribution, teaching and implementation of cognitive enhancement and bias-overcoming techniques. It's even stated in Luke's "So you want to save the world [http://lukeprog.com/SaveTheWorld.html]" list of open problems as "raising the sanity waterline", a major strategic concern for ensuring maximal confidence of results in this incredibly absurd [http://lesswrong.com/lw/j6/why_is_the_future_so_absurd/] thing they're working on.
4Cyan9yThe term in common usage is "n-tuple [http://en.wikipedia.org/wiki/Tuple]".
4DaFranker9yThanks. I paused for a second when I was about to write it, because I realized that I wasn't quite sure that that was how I should write it, but decided to skip over it as no information seemed lost either way and it had bonus illustrative and comical effect in the likely event that I was using the wrong term.

but decided to skip over it as no information seemed lost either way and it had bonus illustrative and comical effect in the likely event that I was using the wrong term.

Given all the evidence on 'bouncy' and 'npple-count' I must admit the comic illustration that sprung to mind may not have been the one you intended!

5TheOtherDave9yYeah, pretty much. It is sometimes useful, at that point, to put aside the goal of becoming better at argument and persuasion, and instead pursue for a while the goal of becoming better at distinguishing true assertions from false ones.
5DaFranker9yInterestingly, the Authority Card seems subject to the Rule of Separate Magisteria [http://wiki.lesswrong.com/wiki/Separate_magisteria]. I'm sure you've also noticed this at some point. Basically, the reputedly-intelligent person will convince anyone of any "fact" by simply saying it convincingly and appearing to themselves be convinced, but only when it is a fact that is part of the Smart-person Stuff magisterium within the listener's model. As soon as you depart from this magisterium, your statements are mere opinion, and thus everything you say is absolutely worthless, since 1/6 000 000 000 = 0 and there are over six billion other people that have an opinion. In other words, I agree that it constitutes somewhat of a problem. I found myself struggling with it in the past. Now I'm not struggling with it anymore, even though it hasn't been "solved" yet. It becomes a constant challenge that resets over time and over each new person you meet.
3Petra9yOf course, as a young person, this obstacle is largely eliminated by the context. Interact with the same group of people for a long period of time, a group through which information spreads quickly, and then develop a reputation for knowing everything. Downside: people are very disappointed when you admit you don't know something. Upside: life is easier. More important downside: you get lazy in your knowledge acquisition.
3beoShaffer9yHi Petra! Minor nitpick, its rationality not rationalism. Rationalism is something completely different [http://plato.stanford.edu/entries/rationalism-empiricism/].
6Petra9yPardon me, that falls into the grey area between typo and mistake, where the word in the brain doesn't come out on the page. I will correct it.

Hi! I found LW by HPMoR like so many other people, and I have found a lot of interesting articles on here. I'm only 12, so there are tons of articles that I don't understand, but I am determined to figure them out. My name is Chloe and I hope that we can be friends!

Hello to all! I'm a 17-year-old girl from Bulgaria, interested in Mathematics and Literature. Since I decided to "get real" and stop living in my comfortable fictional world, I've had a really tough year destroying the foundations of my belief system. Sure, there are scattered remains of old beliefs and habits in my psyche that I can't overcome. I have some major issues with reductionism and a love for Albert Camus ("tell me, doctor, can you quantify the reason why?" ).

In the last year I've come to know that it is very easy to start believing without doubt in something (the scientific view of the world included), perhaps too easy. That is why I never reject an alternative theory without some consideration, no matter how crazy it sounds. Sometimes I fail to find a rational explanation. Sometimes it's all too confusing. I'm here because I want to learn to think rationally but also because I want to ask questions.

Harry James Potter-Evans-Verres brought me here. To be honest, I hate this character with passion, I hate his calculating, manipulative attitude, and this is not what I believe rationality is about. I wonder how many of you see things as I do and how many would think me naive. Anyway, I'm looking forward to talking to you. I'm sure it's going to be a great experience.

5David Althaus9yHi Rada, welcome to Lesswrong! I share your aversion for reductionism, at least from an emotional albeit not epistemical point of view. I'm afraid we have to deal with living in a reductionistic universe. But e.g. this post [http://lesswrong.com/lw/ve/mundane_magic/] might persuade you that even a reductionistic universe can sometimes be quite charming, although by no means perfect. Oh, and yay for Camus!
[-][anonymous]9y 11

I'm male, early 40s who grew up in the midwestern US but have lived in the UK for the past 10 years. I had a very strong evangelical/fundamentalist upbringing, but at the same time an obsessively "rational" attitude which developed in large part from my covert reading of period sf (the sort in which rebellious yet rational engineers outsmarted their rigid hierarchically-minded superiors and their extremely technologically advanced antagonists at the same time). No surprise therefore that my religious beliefs began to dissolve as soon as I went to university, finally coming out of the closet as a de-convert in 1999.

I'm a postdoctoral researcher in cognitive science - with secondary interests in philosophy of science, especially the manner of scientific inference and the different extents to which Bayesian inference has taken hold in different scientific domains at the present time. I've been lurking here for a few years after seeing posts or comments in various places elsewhere by people like ciphergoth and David Gerard (neither of whom I know in person).

I also tend to make way too many parenthetical statements when I write; even though I am completely aware I am overdoing it I just can't avoid it.

Hello. My name is Konrad and I stumbled upon LessWrong a few weeks ago from Reddit. I've browsed some of the main pages since then, but until now haven't committed to reading much. I hope that after registering I'll be able to participate in the community and learn more. I'm 16 years of age and would describe myself as an agnostic theist. I'd also say that I'm curious about knowledge and the world so hopefully I'll learn a lot from this website.

I'm a long-time occasional reader/lurker, since the Overcoming Bias days. I was introduced to this community years ago by Patri Friedman whom I know socially from college. (As long as I'm name-dropping, I also shared a suite with Steve Rayhawk at the same school...) In the past year I read and loved MoR, and took Stanford's online AI class, both of which prompted me to finally go back and read all of the main sequences and related back-material.

My degree is in math and computer science. I currently work as a programmer for the Mozilla project, and I'm trying to work on projects to use technology to solve important problems for humanity. I'm also a parent of a preschooler, which I find creates many new challenges in rationality (even in possibly trivial situations, like teaching children about Santa Claus). And although I am an atheist, I attend a Quaker meeting. Similar to Buddhism, I find (some varieties of) Quaker practice both compatible with and conducive to rational thought. I might find something useful to say about this in discussions here about meditation, religion, and community.

Part of my difficulty is that some humans, such as infants, have less blicket than animals. If its ok to kill animals, then there's no reason to say it's not ok to kill blicket-less humans. Then I realize that even though it's legal to kill animals, it's still something I can't do for anything except certain bugs. Even spiders I let be, or take outside.

Don't worry, there would probably be a baby killing service if it were legal. Just like we have other people to kill animals for us.

Hi all,

My name is Glenn Thomas Davis. I am a 48-year old male living in Warren, NJ with my wife and 5-year old daughter. I was born and raised in Ketchikan, Alaska. I am a creative director for a pharmaceutical marketing agency. I have been interested in science and skepticism since reading Godel, Escher, Bach in my 20's, but became a really serious skeptic and atheist after I started listening to the Skeptics' Guide to the Universe podcast in 2005ish. I beacame a fan of Eliezer and the Singularity Institute after seeing him speak on Bloggingheads 3 years ago, and I recently subscribed to the Overcoming Bias NYC listserve.

Most of my online friends are from the San Francisco Bay Area where I lived for many years. Not exactly the world's most rational bunch, and they don't often appreciate my atheist rants. I have been delaying introducing myself here because I am resistant to putting in the effort and time to become a known presence from the ground up, or even to write a proper introductory post. However, it recently occurred to me I could just share pieces of writing I've already done for other, less like-minded groups. Here's one:

Hello Less Wrong community, I am Kouran.

What follows may be a bit long, and maybe a little dramatic. I'm sorry if that is uncourteous, still I feel the following needs saying early on. Please bear with me.

I'm a recently be-bachelored sociologist from the Netherlands, am male and in my early twenties. I consider myself a jack of several trades – among them writing, drawing, cooking and some musical hobbies – but master of none. However, I do entertain the hope that the various interests and skills add up to something effective, to my becoming someone in a position to help people who need it, and I intend to take action to approach this end.

I found Less Wrong through the intriguing Harry Potter fanfiction story called 'the Methods of Rationality.' The story entertains me greatly, and the more abstract themes stimulate me and I find myself wishing to enter discussions regarding these matters. Instead of bothering the author of the story I decided to have a look here instead. Please note that I write this before having read any of the Sequences and only a few smaller articles. I intend to get on that soon, but as introductions go I feel it is better to present myself first. I hope you... (read more)

It sounds like the Straw Vulcan talk might be relevant to some of your thoughts on rationality and emotion...

6thomblake10yThat's just about right. Humans are massively irrational; but we tend to regard that as a bug and work to fix it in ourselves.
5lessdazed10yBias [http://wiki.lesswrong.com/wiki/Bias] Diamond in a box: --CEV [http://intelligence.org/upload/CEV.html] You imply that there is a standard of rationality people are deviating from. Yes?
5fburnaby10yHi Kouran, and welcome. Your critique of "rationalism" as you currently understand it is, I think, valid. The goal of LessWrong, as I understand it (though I'm no authority, I just read here sometimes), is to help people become more rational themselves. As thomblake has already pointed out, we tend to believe with you in the general irrationality of humans. We also believe that this is a sort of problem to be fixed. However, I also think you're being unfair to people who use the Rationality Assumption in economics, biology or elsewhere. You say that: That's not an assumption that the theory requires. The Rationality Assumption only requires us to interpret the actions of an agent in terms of how well it appears to help it fulfill its goals. It needn't be conscious of such "goals". This type of goal is usually referred to as a revealed preference [http://en.wikipedia.org/wiki/Revealed_preference]. Robin Hanson at Overcoming Bias [http://www.overcomingbias.com/], a blog that's quite related to LessWrong, also loves pointing out and discussing the particular problem that you've raised. He usually refers to it as the "Homo hypocritus hypothesis". You might enjoy reading some related entries on his blog. The gist of the distinction I'm trying to point to is actually pretty well-summarized by Joe Biden: It's my own humble opinion that economists occasionally make the naive jump from talking about revealed preferences to talking about "actual" preferences (whatever those may be). In such cases, I agree with you that a disposition toward "rationalism" could be dangerous. But again, that's not the accepted meaning of the word here. I also think it might be just as naive to take peoples' stated preferences (whether stated to themselves or others) to be their "actual" preferences. There have been attempts on LW to model the apparent conflict between the stated preferences and revealed preferences of agents, my favourite of which was " Conflicts Between Mental Subagents:

It's been a while, so I just wanted to express approval of these welcome threads. A glance over the comments we've gotten over the years should reveal that they really do make people feel welcome and help people get into discussion on the site.

Hi everyone. 23 year old south american software developer/musician here. I've been lurking around and reading for a couple of months now and I've found a lot of useful and interesting information here. It has actually triggered in me a lot of thinking about thinking, about reflexivity and the need for being aware of one's methods of thinking/learning/communicating etc.

I've been having some thoughts lately on the positive aspects of "rationality-motivated" socialization, mainly because of what I've learned of LW's weekly meetups and also because it has been, so far, pretty difficult to find someone who's interested about rationality. The first google searches took me nowhere, though I have still to look somewhere around philosophy/mathematics departments of local universities.

Anyway thanks for the information and the friendly welcome, and also for the big corpus of material you make available.

I'm 22, Male, an undergraduate at Singapore Management University studying information systems. Interest in AI.

I want to live a "good" life, but different people/culture uses different value systems to view life... some focus on the 'Ending', some focus on the 'Journey', some sees no value at all... Therefore, I'm looking for a way to objectively measure the value of a person's life. (not sure if that is even possible)

Found LW while reading up on Singularity. Would love to make some LW friends. feel free to add me on facebook~ http://fb.me/mengxiang

9cousin_it10yTry watching Daniel Kahneman's TED talk The riddle of experience vs memory [http://www.ted.com/talks/daniel_kahneman_the_riddle_of_experience_vs_memory.html] , it's nice and seems relevant to your question.


Long time lurker here.

I'm 26 years old, CS graduate living in Wrocław (Poland), professional compiler developer, cryptography research assistant and programmer. I'm an atheist (quite possibly thanks to LW). I consider the world to be overall interesting. I have many interests and I always have more things to do than I have time for. I'm motivated by curiosity. I'm less risk-averse than most people around me, but also less patient. I have a creative mind and love chellanges. While being fairly successful lone wolf until now, I seek to improve my people skills because I belive I can't get much further all by myself.

When I found LW for the first time, it absorbed me. It took me about 4 months at 4-6h a day to read all of the Sequences and comments. While I strongly disagree with some of the material, I consider LW to have accelerated my personal developement 2 to 3 times simply by virtue of critical mass and high singal to noise ratio. I don't know any better hub for thought (links welcome!). I joined becuse I finally have something to say.


5Swimmer9639yWelcome! If you're interested in making a post, I bet lots of us would be interesting in hearing that story. Join the club! It sounds like you've chosen a good career for someone who likes challenges, too. Agreed–same for me. If anything, the Sequences that I've disagreed with were better for me, in terms of making me think...even if I still disagreed after thinking about it, they were mostly things I had never thought about to that degree of depth before.

Hello; my name is Brian. It is with some trepidation that I post here because I am not entirely sure how or where I can contribute. On the other hand, if I knew how I could contribute then I probably wouldn't need to post here.

I seem to be a bit older than most people whose introductions I have read here. I am 58. I have spent most of my life as a software engineer, electrical engineer, technical writer, businessman, teacher, sailor, and pilot. (When I was young Robert A. Heinlein advised against specialization, an admonition I took to heart.)

My most recent endeavor was a 5-year stint in a private school as a teacher of science, math, history, government, engineering, and computer science/programming. The act of trying to teach these subjects in a manner that provides the necessary cross-connection caused me to discover that I needed to try to understand more about how I think and learn, as my ultimate goal was to help my students determine for themselves how they think and learn. Being able to absorb and regurgitate facts and algorithms is not enough. Real learning requires the ability to discover new understanding as well. (I am rather a fan of scientific method, as inefficient ... (read more)

Greetings fellow Ration-istas!

First of all, I'd like to mention how glad I am that this site and community exist. For many years I wondered if there were others like me, who cared about improving themselves and their capacity for reason. And now I know - now I just need to figure out how to drag you all down to sunny San Diego to join me...

My name is Brett, and I'm a 28 year old Computational Biologist in San Diego, California. I've thought of myself as a materialist and an atheist since my freshman year in college, but it wasn't until after I graduated that I truly began to care about rationality. I realized that though I was unhappy with my life, as a scientist I had access to the best tools around for turning that around - science and reason.

I was born with a de novo genomic translocation on my 1st chromosome that left me with a whole raft of medical problems through-out my childhood - funnel chest, cleft palate, mis-fused skull, you name it. As a result I was picked on and isolated for most of my childhood, and generally responded to stress by retreating into video games and SF novels. So I went to school to study genetics and biology, and I graduated from college with a ... (read more)

3candyfromastranger9yA lot of people that I know seem to think that logic and reason are mostly just important in science, but they can improve so much in everyday life.


I'm a German student-to-be (I am going to start studying IT in October) and I am interested in almost anything connected with rationality, especially the self improvement, biases and "how to save the world" parts. I hope that lesswrong will be (and it already has been to a certain amount) one of the resources for (re-)shaping my thinking and acting towards a better me and a better world.

I came here, like so many others ;-), because I wanted to check out the foundations/concepts behind HPMOR and I could not just leave again. So over the last few months I visited again and again to read some of the sequences and posts.

As I am interested in science, especially physics, maths, technology and astronomy, I have a question that I would like to ask the lesswrong community: What is a fast and secure way of determining the trustworthiness of scientists and scientific papers? I ask this because there is a lot of pseudoscience and poorly done science out there which often isn't easy to distinguish from unconventional/disrupting science (at least not for me).

all the best Viper

Hi everyone! I am still a high school student but very interested in what I read here on LessWrong! I decided to register to contribute to discussions. Until now, I have been lurking but hopefully I will be able to join the conversation in a useful way.

4John_Maxwell9ySorry to hear about that [http://www.paulgraham.com/nerds.html]!

This is an actual testable prediction. Suppose such an exception is found experimentally (for example, self-decoherence due to gravitational time dilation, as proposed by Penrose, limiting the quantum effects to a few micrograms or so). Would you expect EY to retract his Bayesian-simplest model in this case, or "adjust" it to match the new data? Honestly, what do you think is likely to happen?

Honestly, when the first experiment shows that we don't see quantum effects at some larger scale when it is otherwise believed that they should show up, I expect EY to weaken, but not reverse, his view that MWI is probably correct - expecting that there is an error in the experiment. When it has been repeated, and variations have shown similar results, I expect him to drop MWI, because it now longer explains the data. I don't have a specific prediction regarding just how many experiments it would take; this probably depends on several factors, including the nature and details of the experiments themselves.

This is from my personal model of EY, who seems relatively willing to say "Oops!" provided he has some convincing evidence he can point to; this model is derived solely from what I've read here, and so I don't ascribe it hugely high confidence, but that's my best guess.

Hi all! I have been lurking LW for a few months (years?). I believe I was first introduced to LW through some posts on Hacker News (http://news.ycombinator.com/user?id=olalonde). I've always considered myself pretty good at rationality (is there a difference with being a rationalist?) and I've always been an atheist/reductionist. I recently (4 years ago?) converted to libertarianism (blame Milton Friedman). I was raised by 2 atheist doctors (as in PhD). I'm a software engineer and I'm mostly interested in the technical aspect of achieving AGI. Since I was a kid, I've always dreamed of seeing an AGI within my lifetime. I'd be curious to know if there are some people here working on actually building an AGI. I was born in Canada, have lived in Switzerland and am now living in China. I'm 23 years old IIRC. I believe I'm quite far from the stereotypical LWer on the personality side but I guess diversity doesn't hurt.

Nice to meet you all!

Hello everyone!

I am Jayesh Kumar Gupta. I am from Jodhpur, India. I have been interested in rationality for some years now. I came across this site via HPMOR. I had been reading posts on the site for some years now, while trying to wade my way through the gigantic Sequences, but was not confident enough to join this group, (people here seem to know so much). Right now I am an undergraduate student at IIT Kanpur. Hopefully I too will contribute something to the site in the future.


Hello to the LessWrong universe.

I'm 23 years old. A lover of music (Last.fm): Ravel, Mozart, Radiohead, Sigur Rós, Animal Collective. And driven to learn.

My goal right now is to become a philosophy professor, and participate in radical, reason oriented movements to influence social change.

I value the intellect, the body, life, and the universe. I value learning - to improve the lives of others and myself, and to live most accordingly with 'nature.' I value those who direct themselves in a rational manner.

My rationality quest began when I was a child, always using legos to build new things and drawing. Eventually video games came into my life and problem solving drove me. However, due to immaturity and the social life of a middle/high schooler, I never really progress intellectually despite my love for science and 'deep' conversations with friends.
It wasn't until I was 20, and ended my relationship with a girl that philosophical thought dawned upon me. It was sparked by the breakup, because her family was religious and I molded myself to that lifestyle, but when it was over there was nothing there. I suppose, after losing who I thought was the love of my life, I began to se... (read more)

Hi, my name is Alexey, and although I've been around the website for a while and have been an active LessWrongian in real life meetups, I haven't actually introduced myself on the website yet. So here it goes.

I am an undergraduate student at the University of Cambridge, specialising in synthetic biology and aiming to go on to do research in that field. I am interested in raising x-risk awareness within the SynBio community and advancing a safe approach to research in this area.

I was introduced to LW by a friend, and soon realised that there is actually a community of rational people interested in much the same things as I am. I have enjoyed reading the Sequences and have definitely learned a lot.

Since finding the LW website and community has been such a great experience for me, I introduced many of my friends to it, have participated in setting up the Cambridge meetup group; and more recently organised the first meetup in Budapest. I find it very rewarding to be able to talk to and make friends with fellow rationalists!

As for my interests within the scope of LW, I find that I am interested in self-improvement in terms of identifying and overcoming biases, building and expanding rationalist communities and working on x-risk reduction in synthetic biology. In fact, I find that biologists are underrepresented within the LW community and hope that my knowledge of the subject can translate into useful contributions to the discussions here on the LW website, and in real life LW meetups!

I'm reposting this here because there was a thread swap and I didn't get any takers in the former thread. Please let me interview you! It will be fun and wont take up too much time!

Hello, my name is Brett, and I am an undergraduate student at the University of North Texas, currently studying in the Department of Anthropology. In this semester, my classmates and I have been tasked with conducting an ethnographic study on an online community. After reading a few posts and the subsequent comments, LessWrong seemed like a great community on which to conduct an ethnography. The purpose of this study is to identify the composition of an online community, analyze communication channels and modes of interaction, and to glean any other information about unique aspects of the LessWrong community.

For this study I will be employing two information gathering techniques. The first of which will be Participant Observation, where I will document my participation within the community in attempts to accurately describe the ecosystem that comprises LessWrong. The second technique will be two interviews held with members of the community, where we will have a conversation about communication technique... (read more)

Hi, I am Raiden. For most of my life I have been an aspiring rationalist, even though I didn't call myself by that name. I was raised to think that I was some sort of super genius (it was a big shock in my later elementary school years to discover that I wasn't the smartest person in the world). This had the effect of causing me to associate some of my identity with intelligence. This led me to be a traditional rationalist; I had much admiration for the Spock stereotype, and I have been a atheist since childhood despite a fundamentalist religious family. In my freshmen year of high school, I was exposed to some self-help books that led me to seriously consider other virtues besides intelligence to be of value. This slowly revolutionized my view of the world.

Over the course of the next summer, I was exposed to the philosophy of Objectivism, and quickly became a strong adherent to it. I was from the beginning in agreement with the "Open Objectivist" group which said Objectivism is not a complete philosophy.

Hello! I came here researching free will for a school project. I'm currently 18, studying science at a fairly basic level in a small town in Sweden. I've so far read a few articles and the sheer amount of interesting thoughts in the articles made me want to stay. When I read what Lesswrong stands for, I knew I wanted to be a part of it, to try to become a better, hopefully wiser person.

I've liked philosophy for a long time, and don't usually like "because" as an answer for anything. I want to find out reasons behind everything. I'm so far not as good as I wish, due to limited time and wanting to read a lot of the articles, but not having enough time. However, I find it difficult to abandon half-read articles, even though they can be a bit of a long read compared to what I'm used to, excluding books.

Since I'm easily influenced by new ideas, too, as long as they make sense, I'm expecting myself to switch a lot. Lesswrong seems interesting, anyway, and I want to know more. I want more perspectives and thoughts. So far Lesswrong seems wonderful, and I think I'll like it. Hoping the community can oversee shortcomings when needed, but I'm expecting you all to be a nice bunch.

For science, and a greater understanding. Hopefully I'll be able to learn from you. But it's late now, and I'll be going now. Just thought I'd say hi.

Hello. I'm a 19-year-old student at Stanford University majoring in Computer Science. I'm especially interested in artificial intelligence. I've been reading lesswrong for a couple months and I love it! There are lots of great articles and discussions about a lot of the things I think about a lot and things that I hadn't thought about but proceeded to think about after reading them.

I've considered myself a rationalist for as long as I can remember. I've always loved thinking about philosophy, reading philosophy articles, and discussing philosophy with other people. When I started reading lesswrong I realized that it aligned well with my approach to philosophy, probably because of my interest in AI. In the course of searching for a universal epistemology I discovered Solomonoff induction, which is an idea that I've been obsessed with for a couple years. I even wrote a paper about it. I've been trying to apply this concept to epistemology and cognitive science.

My current project is to make a practical framework for resource-bounded Solomonoff induction (Solomonoff induction where the programs are penalized for taking up too much time). Since resource-bounded induction ... (read more)

I'm sorry about your turmoil, but I don't take responsibility for "creating" it.

First, any single relaxed taboo is a blow against the entire net of ethical inhibitions

This is not an uncontested statement.

I've posted a few rationality quotes, so it sounds like time to introduce myself. I'm a 22 year old software project manager from Wisconsin, been reading LW since June or so when MOR was really going strong.

I've been a very rational thinker for my whole life, in terms of explicitly looking for evidence/feedback and updating behaviors and beliefs, but only began thinking about it formally recently. I was raised Christian, and I consider my current state the result of a slow process of resolving dissonance based on contradictions or insufficient/contrary evidence. I'm most interested in theory of government and achieving best results given the rather unreliable ability of voters to predict or understand outcomes of different policies.

I also think, though, that ethics is just as important as rationality- choosing the correct goals is just as necessary as succeeding towards those goals. I've seen appreciation of this within LW that, for me, really sets it apart, so I hope I can make a larger contribution. As someone once said, the choice between Good and Evil is not about saying one or the other, but about deciding which is which.

Hello, I'm a high school senior who discovered this site somewhere on reddit and deeply enjoyed this article (http://yudkowsky.net/rational/the-simple-truth) and decided to check out more posts. I'm planning on studying engineering in college but I try to have a well-rounded knowledge on a myriad of subjects apart from math and science. The content here is very enticing and intellectually stimulating, and I will probably frequent this site in the future.

It happens to all of us sometimes, and it's perfectly acceptable to ask for an explanation.

I'd like to note that while acceptable to ask for an explanation, it is downright counterproductive to be petulant. Don't bother getting upset until you know why.

Hello lesswrong community!

"Who am I?" I am a Network Engineer, who once used to know a bit of math (sadly, not anymore). Male, around 30, works in IT, atheist - I think I'll blend right in.

"How did I discover lesswrong?" Like the vast majority, I discovered lesswrong after reading HPMOR many years ago. It remains my favourite book to this day. HPMOR and the Sequences taught me a lot of new ideas and, more importantly, put what I already knew into a proper perspective. By the time HPMOR was finally finished, I was no longer sure where my worldview happened

3habryka1yWelcome! Glad to have you join us!
3jeronimo1961yThank you! You have no idea how happy your reply makes me! In an irrationally large part, because I've seen your name in a book, but I just cannot help myself. You are alive! (Duh!) More importantly, the lesswrong community is alive! (Double Duh!, but going through the Sequences' comments can be a bit discouraging - like playing the first levels of a MMORPG, while the experienced player base has moved on to level 50.) Hopefully, we'll have many interesting discussions once I catch up. So much to look forward to! Will Alicorn be there? Will TheOtherDave explain what happened to the original Dave? You guys are legends. P.S. Sorry for the delayed response, I didn't notice the number next to the bell earlier. I'll make sure to check it frequently from now on.
3habryka1yGlad to hear that! :) Looking forward to many future conversations, and sorry for the bell icon not being as obvious.

Hello to the LW Community. My name is Glenn, 49, from Boulder, Colorado. After completing my Master's degree in Economics, I began a career in investment management, with a diversion into elected politics (a city council, a regional council of governments, then the Colorado state legislature, along with corporate on non-profit boards). My academic work focused on decision theory and risk analysis and my vocation on their practical application.

Hi! My name is Paul, and I've been an aspiring rationalist for years. A long time ago, I realized implicitly that reality exists, and that there is only one. I think "rationality" is the only reasonable next thing to do. I pretty much started "training" on TvTropes, reading fallacies and the like there, as well as seeing ways to analyze things in fiction. The rules there apply to real life fairly well.

From there, I discovered Harry Potter and the Methods of Rationality, and from there, this site. Been reading quite a bit on and off over... (read more)

Hello, everyone! I'm 21, soon to graduate from IIT Bombay, India. I guess the first time I knowingly encountered rationality, was at 12, when I discovered the axiomatic development of Euclidean geometry, as opposed to the typical school-progression of teaching mathematics. This initial interest in problem-solving through logic was fueled further, through my later (and ongoing) association with the Mathematics Olympiads and related activities.

Of late, I find my thoughts turning ever more to understanding the working and inefficiencies of our macro-economy, ... (read more)

Hello folks! I'm a student of computer science, found Less Wrong a few years ago, read some articles, found myself nodding along, but didn't really change my mind about anything significant. That is, until recently I came across something that completely shattered my worldview and, having trouble coping with that, I found myself coming back here, seeking either something that would invalidate this new insight or help me accept it if it is indeed true. Over the past few days, I have probably been thinking harder than ever before in my life, and I hope to contribute to discussions here in the future.

Hi everyone. I have been lurking since the site started, but did not have the courage to start posting until recently.

Science and science fiction socialized me and made me curious about the inner working of the universe.

Welcome to Lesswrong. We like rationality because it helps us achieve our goals. You might call it optimizing our lives.

Unfortunately, mass media portrayals of "rationality" make it seem like smart people want to lose all emotions and become Vulcan. That's a stupid goal, and not what we mean by rationality

If you have something you want to talk about, click Discussion in the heading, then post in the open thread.

Hello, all.

I'm an agnostic artist and general proponent of thinking (although I hope to become a more specific proponent of thinking now that I'm here) who enjoys working behind the scenes.

I'm the new executive assistant for the Center of Modern Rationality, and look forward to doing what I can to help get the Center running as smoothly as possible. If I'm doing my job right, you shouldn't even know I'm here.

Well, OK, let's examine it then.

We have some activity.
We see no particular reason to prevent people from doing that activity.
We see no good reason for people to do that activity.
We have a proposed law that makes that activity illegal.
Do I endorse that law?

The only case I can think of where I'd say yes is if the law also performs some other function, the benefit of which outweighs the inefficiencies associated with preventing this activity, and for some reason separating those two functions is more expensive than just preventing the activity.

I often "claim" my downvotes (aka I will post "downvoted" and then give reason.) However, I know that when I do this, I will be downvoted myself. So that is probably one big deterrent to others doing the same.

On the other hand if people agree with your reasons they often upvote it (especially back up towards zero if it dropped negative).

For one thing, the person you are downvoting will generally retaliate by downvoting you (or so it seems to me, since I tend to get an instant -1 on downvoting comments)

I certainly hope so. I would... (read more)

4[anonymous]10yDo you think that's a good thing, or just a likely outcome? Downvoting explanations of downvotes seems like a really bad idea, regardless how you feel about the downvote. It strongly incentives people to not explain themselves, not open themselves up for debates, but just vote and then remove themselves from the discussion. I don't see how downvoting explanations and more explicit behavior is helpful for rational discourse in any way.
6MixedNuts10yThis is exactly the reaction I want to trolls, basic questions outside of dedicated posts, and stupid mistakes. Are downvotes of explanations in those cases also read as an incentive not to post explanations in general?

If by "rationalist", the LW community means someone who believes it is possible and desirable to make at least the most important judgements solely by the use of reason operating on empirically demonstrable facts, then I am an ex-rationalist.

By age 28 or so, I concluded that most of the really important things in life were not amenable to th... (read more)

8orthonormal10yWelcome! You'll be relieved to know that's not quite the Less Wrong dogma [http://lesswrong.com/lw/31/what_do_we_mean_by_rationality/]; if you observe that your conscious deliberations make worse decisions in a certain sphere than your instincts, then (at least until you find a better conscious deliberation) you should rely on your instincts in that domain. LWers are generally optimistic about applying conscious deliberation/empirical evidence/mathematical models in most cases besides immediate social decisions, though.

Hi everyone. I am an engineering graduate student in the SF Bay area, and will be working at a tech company in the south bay starting in the summer.

I have been lurking on this forum for about a year and a half, but this post convinced me to register for an account. I serendipitously found Less Wrong through an interesting post about the Amanda Knox murder trial. I have read a few of the sequences and all of MoR. I hope to get more involved in the future!

Retired Mechanical Engineer with the following interests/prejudices.

Longstanding interest in philosophy of science especially in the tradition of Karl Popper.

Atheist to a first approximation but I can accept that some forms of religious belief can be regarded as "translations" of beliefs I hold and therefore not that keen on the "New Atheist" approach.

Just remember that if it ends with -us, it probably pluralizes to -i. That's only for latin-based words. Greek-based words, like octopus, can either be pluralized to octopuses or octopodes (pronounced Ahk-top-o-dees). And sometimes you have a new or technical latin-based word like "virus" which just pluralizes to "viruses." It's perfectly fine to pluralize uterus to uteruses, too, since it's so uncommon. English is a bitch.

Obviously, I can't speak for the site as a whole... then again, neither can anyone else. Basically, it's complicated, because the site isn't homogenous. Expressing conventionally "bad" moral views will usually earn some downvotes from people who don't want such views expressed; expressing them clearly and coherently and engaging thoughtfully with the responses will usually net you upvotes.

5pragmatist9yWelcome to LessWrong! Here are some answers to your questions about MWI: 1. The space of possibilities in MWI is given by the configuration space of all the particles in the universe. The configuration space consists of every possible arrangement of those particles in physical space. So if a situation can be realized by rearranging the particles, then it is possible according to MWI. There is a slight caveat here, though. Strictly speaking, the only possibilities that are realized correspond to points in configuration space that are, at some point in time, assigned non-zero wavefunction amplitude. There is no requirement that, for an arbitrary initial condition and a finite period of time, every point in configuration space must have non-zero amplitude at some point during that period. Anyway, thinking in terms of worlds is actually a recipe for confusion when it comes to MWI, although at some level it may be unavoidable. The imporant thing to realize is that in MWI "worlds" aren't fundamental entities. The fundamental object is the wavefunction, and "worlds" are imprecise emergent patterns. Think of "worlds" in MWI the same way you think of "blobs" when you spill some ink. How much ink does there need to be in a particular region before you'd say there's a blob there? How do you count the number of blobs? These are all vague questions. 2. MWI does not play nicely with quantum field theory. The whole notion of a false vacuum tunneling into a true vacuum (which, I presume, is what you mean by vacuum decay) only makes sense in the context of QFT. The configuration space of MWI is constructed by considering all the arrangements of a fixed number of particles. So particle number is constant across all worlds and all times in configuration space. Unlike QFT, particles can't be created or destroyed. So the configuration space of a zero-particle world would be trivi

Hey everyone,

I'm a 20 year old student of Serbian literature (from Serbia). I found this site while browsing through some math blogs and it seems very nice.

About me: Currently my main interest is writing short stories. I view them as arranging words so they appeal to my own emotions, intuition, subconscious, what not. I also like mathematics and I like to explore relations and find out new rules between numbers, lines, etc., although it sometimes bores me because my imagination has to be strictly inside the boundaries of logic there, while with literature ...

I'm 41, working on a wiki project for sustainability and development, which I love (and part-time on a related project which I like and actually get paid for). I use the same username everywhere, so if you're curious, you won't have trouble finding the wiki project.

I'm a one-time evangelical Christian. I think it was emotional damage from my upbringing that made me frightened to let go of that, and I stayed a believer for 9 years, starting in my late teens. I took it extremely seriously, and there were good things about that. But with hindsight, I would di... (read more)

I recently found myself making a rather impassioned defense of how living logically does not preclude living morally. As I have found monitoring my actions to be more reliable than introspection, this was a much better confirmation of "I think this is the right thing to do" than my saying to myself that I think this is the right thing to do.

Other proximate causes include TVTropes via Methods of Rationality (obviously), one of my acquaintances linking several articles in succession from this site, and the fact that I find myself extremely prone... (read more)

Hi. I'll mostly be making snarky comments on decision theory related posts.

4windmil10yHey! If I find the time I'll be making snarky comments on your snarky comment related posts.

I'm being a fucking idiot tonight.

If I downvote you for calling a valuable lesswrong contributor a fucking idiot is that a compliment or a criticism? ;)

7TheOtherDave10yIf I tell you you have a perverse wit will you hold it against me?

Downvoted for sarcasm. I was under the impression that (unsubtle forms of) sarcasm in non-humorous discussions are outlawed on LW, and that's very OK with me.

Downvoted for being a wet blanket and incorrect assumption of sarcasm. If it's ok to talk about the implications of legalizing infanticide then it is ok to follow the weirdtopia through and have fun with it. I adamantly refuse to take on a sombre tone just because people are talking about killing babies. My due diligence to the seriousness of babykilling with my expression of clear opposition - wit...

What makes you so quick to dismiss your interlocutor

You're spinning this into a dismissal, disrespect of Bakkot's intellectual capability or ability to reason. Yet disagreement does not equal disrespect when it is a matter of different preferences. It is only when I think an 'interlocutor' is incapable of understanding evidence and reasoning coherently (due to, say, biases or ego) that observing that reason cannot persuade each other is a criticism.

For legal reasons, there'd just have to be a clear procedure where parents would take or refuse the decision, probably after being informed of the baby's overall condition and potential in the presence of a witness. I can't imagine how it could be realistically practiced without one.

That said, I do understand the "it's OK for it to be true but you can't say it" mainstream social convention, which is what you seem to be invoking.

6[anonymous]10yAre those property rights transferable? Would you permit a market in infants?
8[anonymous]10ySure, adoption markets basically already exist, why not make them legal? Not only are wealthier people better candidates on average because they can provide for the material needs much better and will on average have a more suitable psychological profile (we can impose legal screening of adopters too, so they need to match other current criteria before they can legally buy on the adoption market if you feel uncomfortable with "anyone can buy"). It also provides incentives for people with desirable traits to breed, far more than just subsidising them having kids of their own.
5gwern10yOne of the standard topics in economic approaches to the law is to discuss the massive market failures caused by not permitting markets in infants; see for example, Landes and Richard Posner's "The Economics of the Baby Shortage" [http://sbm.temple.edu/ccg/documents/adoptionLandesPosner.pdf]. I thought their analysis pretty convincing.

The photons come from unjustified pattern-matching.

It's too long ago for me to remember clearly, but I think I found OB while I was reading about transhumanism, which I was very interested in.

I'm a new member, and I want to say hello to this awesome community. I was led to this website after encountering a few people who remarked that many of my opinions on a wide range of subjects are astonishingly similar to most of the insights that have been shared on LessWrong so far. Robert Aumann is right -- rational agents cannot agree to disagree. ;-)

I am sure there are many things I can learn from other LW readers, and I look forward to participating in the discussions whenever my busy schedule allows me to. I would also like to post something that I wrote quite some time ago, so I'll do the shameless thing and ask for upvotes -- please kindly upvote this comment so that I will have enough karma points to make a post!

0 and 1 are not probabilities anyway, so refusing to call someone an atheist (or a theist) because they assign a non-zero (or ‘non-one’) probability to a god existing seems pointless to me, because then hardly anyone would count as atheist (or a theist). (It's also a fallacy of gray, because assigning 0.1% probability to a god existing is not the same as assigning 99.9% probability to that.)

Out of curiosity how does science explain people feeling knowing that people they care about are in trouble?

I don't know if this is something that has been explained, or even if it's something that needs to be explained. It could be that you're operating under an unrepresentative dataset. Keep in mind that if you hadn't experienced a number of phone calls where the caller's intuition that something was wrong was correct, you wouldn't treat it as a phenomenon in need of explanation, but if you had experienced some other set of improbable occurrences, sim...

That may be the case, and I won't disagree that some claims are fabricated.

However because their beliefs about why the gifts were given are wrong, the fact that the gifts were given remains.

4Jakinbandw9yBut but what if you get inconsistent result? Let's say you try the ritual 5 times and the placebo 5 times and it works 2 times for the the ritual and twice for the ritual. Furthermore consider that nothing changed in any of these tests that you could measure. You said the ritual was spiritual, and there for asking for divine intervention. It could be that the ritual was unnecessary and that the divine being decides when it intervenes. If you can't figure out why it sometimes works, or sometimes doesn't than maybe it's because you are asking a sentient being to make a choice and you don't understand their reasoning. You could say that there was no divine intervention at all, but then you are left trying to come up with more and more complex theories about why it sometimes works and sometimes does not. This might not be a bad thing, but one shouldn't discount the easy solution just because it doesn't match their expectations, nor should they stop looking for another solution just because any easy one that is hard to test is present. Oooh! I like it! Yeah sure, I can get behind that. The reason that i am not trying to convince people here of Christianity is because I don't have proof that I feel should convince other people. If I did convince anyone here, with the proof that I have, then I would feel that I had made you inferior rationalists. On the other hand I cannot just ignore my own observations and tests and agree with you when I perceive that you are mistaken. I hope that one day I might find some way of proving that god exists to people without needing them to experience something supernatural themselves. But unfortunately as I believe that I am dealing with a sentient intelligence I feel that is unlikely.
8Desrtopa9yAny test with such a small sample size is barely worth the bother of conducting. You'd want to try many times more than that at least before you start to have enough information to draw reliable inferences from, unless the effect size is really large and obvious, say, all five people on the real ritual get better the next day and none of the five on the placebo recover within a week. People recover from most ailments on their own for perfectly natural reasons. Some people fail to recover from ailments that other people recover from, but it's not as if this is an incomprehensible phenomenon that flies in the face of our naturalistic models. If no proposed supernatural intervention changes a person's likelihood of recovery relative to placebo, then it could be that there's no way of isolating supernatural intervention between groups, but a much simpler explanation to account for the observations is that no supernatural interventions are actually happening. People used to see the appearance of supernatural intervention everywhere, but the more we've learned about nature, the less room there's been for supernatural causes to explain anything, and the more they've become a burden on any model that contains them. It's possible that some phenomena which are unexplained today can only be explained in the future with recourse to supernatural causes, but given the past performance of supernatural explanations, and the large amount of informational complexity they entail, this is almost certainly an unwise thing to bet on. I'm glad you're comfortable with this sort of environment. If you're going to make judgments on the basis of your own experience though, it's good to try to incorporate the evidence of others' experience as well. Personally, from around the age of ten to twelve or so, I experimented a lot with the possibility of god(s). I tried to open myself up to communication with higher intelligences, perform experiments with prayer and requests for signs, and so

Well, mass hysteria is a real thing, but if a large group of people who have no prior reason to cooperate all claim the same unusual observations, it's certainly much stronger evidence that something unusual was going on than one individual making such claims.

Many, possibly even all religions though, make claims of supernatural events being witnessed by large numbers of people, and religions make enough mutually exclusive claims that they cannot all be true, so we know that claims of large scale supernatural observations are something that must at least so...

Hello, everyone. It's a pleasure to be here. I look forward to participating in discussions.

Good point. Though I guess we could still say that the weak AI is recursively self-improving in this scenario -- it's just using the developers' brains as its platform, as opposed to digital hardware.

Can't we limit the meaning of "self-improving" to at least stuff that the AI actually does? We can already say more precisely that the AI is being iteratively improved by the creators. We don't have to go around removing the distinction between what an agent does and what the creator of the agent happens to do to it.

In the context of LW, all those terms are pretty closely related unless some more specific context makes it clear that they're not. X-rationality is a term coined to distinguish the LW methodology (which is too complicated to describe in a paragraph, but the tagline on the front page does a decent job) from rationality in the colloquial sense, which is a much fuzzier set of concepts; when someone talks about "rationality" here, though, they usually mean the former and not the latter. This is the post where the term originates, I believe.

hello! I was introduced to LessWrong through HPMOR. I find rationality interesting as someone who was brought up in an extremely religious household, and trying to wade through what I actually believe rather than what I was taught.

Hello, I am Kris,

I study Mathematics and Computer Science at Oxford, I am interested in learning about Bayesian statistics/machine learning and its principles (Cox's theorem, Principle of MaxEnt) and tend to do things (overly) rigorously.

From my very limited experience, it appears that lesswrong applies these principles to real life, which is interesting as well, but at the moment I am more focused on Jaynes' "robot model".

I really like Jaynes' book, however it has come to my attention that some parts are outdated/unrigorous and I'm hoping that this forum will tell me what the state of the art is.

I think various forms of "optimization" would probably fit the bill. That is, pretty much everything this site endorses about "rationalists" it would also endorse about "efficient optimizers."

Consider this (and this related thread) from the genes' point of view. It may be worth having all of your carriers do risky things, if the few that die of them are more than made up for by the ones who survive and learn something from the experience (such as how to kill big fierce animals without dying).

For a gene, there's nothing reckless about having your carriers act recklessly at a stage in their lives when their reproductive survival depends on learning how to do dangerous things.

5Emile10yGiving respect to controversy for the sake of controversy is just inviting more trolling and flamewars. I have respect for true ideas, whether they are outmoded or fashionable or before their time. I don't care whether an idea is original or creative or daring or shocking or boring, I want to know if it's sound. The fact that you seem to expect increased respect because of controversial opinions makes me think that you when you wrote about your support for infanticide, you were motivated more by the fact that many people disagreed with you, than by the fact that it's actually a good idea that would make the world a better place.

I'm a 21 years old and study medicine plus bayesian statistics and economics. I've been lurking LW for about half a year and I now feel sufficiently updated to participate actively. I highly appreciate this high-quality gathering of clear-thinkers working towards a sane world. Therefore I oftenly pass LW posts on to guys with promising predictors in order to shorten their inferential distance. I'm interested in fixing science, bayesian reasoning, future scenarios (how likely is dystopia, i.e. astronomical amounts of suffering?), machine intelligence, game theory, decision theory, reductionism (e.g. of personal identity), population ethics and cognitive psychology.

I'm 29, and I am a programmer living in Chicago. I just finished up my MS in Computer Science. I've been a reader of Less Wrong since it was Overcoming Bias, but never got around to posting any comments.

I've been rationality-minded since I was a little kid, criticizing the plots and character actions of stories I read. I was raised Catholic and sent to Sunday school, but it didn't take and eventually my parents relented. Once I went away to college and acquired a real internet connection, I spent a lot of time reading rationality-related blogs and websites. It's been a while, but I'd bet it was through one of those sites that I found Less Wrong.

3[anonymous]9yWell, the standard response to the whole 'agnostic' debate is that while probability is subjective, pobability theory is theorems [/lw/o6/perpetual_motion_beliefs/]: You and I are only ever allowed to assign credence according to the amount of evidence available [/lw/o5/the_second_law_of_thermodynamics_and_engines_of/], and the God hypothesis has little, so we believe little.
