I'm 90% extrovert, live in São Paulo, am 27.

My experience of living with my father from 15-25 has been interesting for many reasons: Learning to accept that different people have different thresholds of tolerance for noise, dirt, social interaction, how active you are in the morning etc... More than anything dinner time was a time to share the perks and perils of our day, like many tribal societies do. We lead very different lives (philosopher and EA versus engineer at a big company).

Currently I live alone and my girlfriend comes over frequently. I don't like living alone. Probably I should hate living alone, but the human mind is not that good at attaching the right emotions to the right consequences, as anyone in the EA movement, or anyone who ever ate unhealthy sweets can tell. Living alone puts the entire burden of responsibility on what I do with my time on me. All the thresholds are my thresholds. The house is exactly as I tolerate it to be (modulo when my GF comes), The daily happenings are exactly what I allow to penetrate my attention. Sounds like great for productivity right? but it isn't. The LW study hall helps when the problem is just feeling lonely. But nothing helps when the problem is needing outside random input from someone whose ideas you care about.

Thus I envy people who live with friends. I envy them only less than people who work with what they love with friends. They have someone to talk to about the things they are excited without having to use the web or go out to meet a friend to do it. (in a big city, meeting someone could remove 1 hour from your day due to traffic). I've also heard people saying that the best heuristic is to live with friends who are not your very best friends, since cohabiting causes friction between close friends.

I have experienced three ways of living: 1) with my mother, 2) alone, 3) with my girlfriend. It is difficult to evaluate the impact of the first two options, because that also happens to be a difference between my school years and work years.

During the school years when I lived with my mother, I was most productive. The school gave me a fixed schedule when I had to leave my home (which made all other activities outside of my home less trivially inconvenient, which in my case matters a lot). I didn't have a good relationship with my mother, and that fact encouraged me to spend even more time outside. So despite being introverted, I met many interesting people and did a few interesting things. (For example I was a coordinator of Amnesty International in Slovakia, or an amateur editor of a science-fiction magazine.) From inside, I was always funny and laughing outside of my home, and silent and depressed at home; people who knew me in one of these modes would probably not recognize me in the other one.

When I ended school, I strongly focused on making money and relatively soon bought my own home. I lost most of my social networks. Living in my own home worked like magic for my self-esteem and inner peace. No one there to criticize me every day and make fun of everything I consider valuable. My personality became stable, calm... and rather lazy and probably a bit boring, I have to admit. Gradually I started spending more time alone at home, on internet. I missed the contact with cool people, but I wasn't strategic enough to find a solution. So to have some interesting interaction and communicate with cool people, I spent even more time at the internet, etc. Luckily, a very good friend of mine lived just a few streets away from me. We spent a lot of time talking and playing computer games together.

Now my girlfriend is living with me, significantly improving my life. She provides me social contact on those days when I only go to work and back home. She invites me to some social activities, I invite her, and then we have interesting things to discuss. She also reads LW; and generally, she is smart. In addition of all other benefits of having a girlfriend, it is so good to have a smart and rational person near to interact with on a daily basis. It feels like living in a saner world.

In general I consider myself introverted, because I don't mind doing an interesting project alone for hours (though it is difficult to resist the templation of going online instead), and I feel comfortable in smaller groups talking about meaningful topics, and uncomfortable trying to have a small talk in a large group. This is partially a consequence of lack of some social skills, and the fact that I consider many people painfully boring. With more interesting people around me, I am sure I would spend more time socially and feel less exhausted by it; but my social activity would probably still be less than average.

For decades I dream about having a tribe of people like me here. I know a few individuals that would pass my filter. With better social skills and better strategy, I could find some more. Not sure if they have a desire for such tribe, and whether they would accept each other, though. (One negative piece of evidence is that LW exists, I have translated over a hundred articles to my language and posted them on facebook, we had a few LW meetups here... so, if there were many people thinking like me, they would already come running.) There are some similar tribes which I should explore; I am doing it, just extremely slowly. I believe that a small group of x-rational people acting together could visibly improve the environment around them. I would like to have both a nice tribe to belong to and satisfy my social needs and do some local optimization. At this moment, I can only have the two things separately (support some goood cause with my work or money, and hang around with irrational people).

Somewhat introverted, living in London, 23 M.

I've done all three, plus living with nonfriends. Living alone versus living with friends feels like a trade-off. Currently I live alone, and it's nice not to have to coordinate with anyone about cooking, cleaning, etc., or to ever have people around when I'd rather they not be, that sort of thing. When I was living with friends, if I'd been living alone I would have had almost no social interaction, and that would probably have made me unhappy-without-realising-it, but that's not currently a problem. On the other hand, living with friends means I get to spend more time with them; and sometimes I need a hug or a shoulder to cry on or advice that I don't want overheard, and that's much harder to get when I live alone.

Living with nonfriends or family combines the bad parts of both of those. Family is worse for reasons that I can't express very well and don't feel like going into. (Not that I have a bad relationship with them; I just don't have a particularly good one, either.)

Overall I have a preference for being alone. Having other people around often bothers me, in particular if I have to share my time between paying attention to them and pursuing other (lonely) activities which I'd rather do instead.

However, I also can't feel happy without at least some human presence/interaction. I know if I stay alone with no contact at all for more than a few days, I'll feel lonely and start craving some human company. The way I balance these two impulses in practice, is to live with the same person who I get along with well, almost 24 hours a day, day after day, and have otherwise very few other contacts with other people. This is in no way perfect, but it's better than any alternative I can think of.

Overall, I tend to dislike interacting with/within groups of people more than with individuals. I particularly enjoy discussing interesting topics, so long as it's just with one person. I'm often disappointed in people, have fairly high standards, and only a few topics of interest which I like to share. This severely limits the amount of people, and circumstances in which I can pleasantly interact with them. I can still interact with just about anybody, I just don't enjoy the perpetual strain I experience when doing so.

I am an introvert, male, early thirties. I live alone, interacting rarely with other humans. I play video games, read books and browse the net. I do my job remotely, turning emails from my boss into checkins to my source control.

The life of the hermit is underrated.

It is an excellent existence. It might not be for everyone, but I think you should give it a month or so. You cannot let anyone down, hurt them or be hurt by them. You cannot waste their time, or ruin their day. Your time is entirely your own, and you can indulge in any whim which strikes your fancy, or devote yourself entirely to a project of your own choosing.

I don't have a lot to say about my friend's experiences, for the obvious reason.

I'm fairly introverted and highly independent. I have a great deal of willpower and find self-motivation easy. Here are my living experiences after moving out from my parent's home:

• University dormitories: I initially thought I would hate it, due to all the shared space. However, I had a great experience, as I got along well with most of my hallmates. While my roommate and I were sufficiently different to not be great friends, we were able to share a room without conflict. The lack of privacy was difficult for me to deal with, and not having my own space was tiring. I would not share a room with a person again (even a romantic interest), except under great need.

• Apartment #1 with good friends: The apartment was big, so everyone had lots of space and privacy. I really liked this -- there were some roommate conflicts (mostly over under communicated expectations re: chores), but otherwise, everything went well. I'd gladly live in a shared space with like minded people.

• Apartment #1 with bad friends: This was not so fun. I initially thought it would be great, as I was better friends with the new roommates at first. However, after a few months, they ceased doing any chores, and eventually two of them moved out, owing me $500. This came as a complete surprise, as I had no reason to distrust them prior to living with them. This made me aware that agreeing to share a lease with someone was a massive risk.

• Apartment #2 with quiet/distant roommates: This apartment was a decent amount smaller, but everyone still had enough space and privacy. My roommates were quiet, highly introverted, and never really left their room. I detected some unspoken hostility towards the end of their stay, but was never sure why. Living with them was moderately stressful, as I felt like any use of the space was a slight intrusion due to the non-friendly nature of the situation. After they became hostile, it became stressful to be in my apartment, and I don't want that to happen again.

• Apartment #2 living alone: I LOVE THIS. The additional space to have more specialized areas is really nice (I now have a bedroom for sleeping/fucking and an office for recreation/work). If I want to play music or have quiet, I know i'm not imposing on anyone. I know there is no risk of bad roommates stealing or exposing me to financial risk.

Right now, living on my own has been preferable to any other situation. I view getting a roommate as a cost-saving measure -- and the quality of the roommate would have to be sufficiently high that I didn't feel like accepting the loss of autonomy, risk of financial harm, and exposure to theft were great enough to counterbalance the savings on rent and utilities.

In the past several years, I've been in different environments:

—Living in a boardinghouse in DC with people who I didn't really know. This was alright for happiness, but horrible for productivity because I had no social motivation to get anything done, and it turns out humans are social animals.

—Living with my parents in Boston. This was better for productivity, since they were interested in what I was doing with my time and my progress towards my goals, but reporting my progress wasn't exactly fun and it caused tension in the relationship.

—Living in the Boston rationalist house with half a dozen friends. This had the same benefits of talking about goals and getting social points for making progress. The dynamic felt a lot better because I was interacting with peers instead of parents, and it was easier to vanish into my room for a couple days when I wanted to. Also having house coworking or strategizing events is a big plus. A majority of residents (possibly all) had a similarly positive experience.

—Living and working with Leverage Research in Oakland. Like the above, but more.

To answer your demographic questions, I'm 25 years old, originally from Boston, and think the introvert/extrovert model is extremely silly but will answer "mostly introvert" in the spirit of not screwing up your data.

I've slowly come to have a strong belief that the main problem with people I know who are suffering, or failing to achieve their goals, is living with fewer tribal affiliates than they "need".

This seems plausible.

70% introvert, 26 yo, San Francisco.
Lived by myself and it was very much not fun. I didn't even realize how much not fun it was until I started living with awesome people. And it makes me feel a lot better leaving in a somewhat large decorated apartment, rather than the minimalist cube flat I created for myself prior to that. Currently living with my girlfriend.

Mostly introvert. Early 40s. Living near Cambridge, UK. Working in a technology startup doing mathematics, software, engineering, occasional science.

I'm not sure my anecdotal evidence will be much use -- I have few meaningful comparisons to report, and so far as I can tell the result of each comparison is "not much changed" -- but I'll give it anyway on the grounds that it's better not to bias your results by suppressing things that seem boring or uninformative.

I've lived with my parents, before going to university (and between university terms as a student). I was in more or less full-time education all that time, so comparisons with later life may not be relevant. I don't recall having any very impressive goals at the time beyond doing well in my studies. I did do well in my studies, and read a lot of interesting things.

I've lived on my own in university-provided accommodation, while doing postgraduate study. That was for only about a year. Motivation and happiness were fine so far as I can recall.

I got married at about the same time as I started my PhD, and have lived with my wife since then. My motivation and productivity have been very variable, depending on things like how well my work was going (there is of course a feedback loop here) and the health of my marriage (again, feedback loops; unhappy people are harder to live with). My wife is intelligent and nice but not particularly rationalist.

About 7 years ago two things changed simultaneously: our daughter was born, and I abandoned (a somewhat-rationalist version of) Christianity in favour of atheism. My wife remains a Christian. (So I suppose there's less tribal affiliation now, in some sense). So far as I can tell, there was no particular change in my happiness or motivation or productivity at that point. It's hard to isolate the consequences of those changes because they happened at about the same time -- and, also at about the same time, I changed jobs and moved house.

In general I would describe myself as moderately happy, not very strongly motivated, and more productive than most people but substantially less than I could be if I were strongly "driven". None of this seems to me to have changed dramatically over my adult life to date.

I don't think I have enough insight into my friends' and colleagues' motivation to warrant trying to say anything about them here.

I'm an introvert, hometown is Detroit. I was happiest when living with my family, although that may have been because of other factors related to being young. I moved out at 17 to go to college, and lived alone for five years, until I moved in with my current roommate. There is no doubt that living with a roommate has been better for me. I find it is much harder to get into a downward spiral when there is someone else living with me. In spite of this, I do sometimes wish I still lived alone. I know it was worse for me, but it was so much easier.

75% introvert, living alone was much better for productivity and happiness because I was better able to regulate "interruptions" like hanging out with friends etc., by planning when I went out and when I came back.

I lived for a while with 4 roommates and that was terrible for productivity, as there was a constant background noise of talking or music (I need silence for concentration, so maybe not applicable if you don't), which sometimes went very late into the night. It was a positive for happiness however, as we lived in a "hip" part of town and everyone got along fairly well, so there was a lot of opportunity for quality social experiences.

Currently I live with my girlfriend and a close friend. For productivity it's been pretty good, but mainly because my girlfriend is also a graduate student so it's easier for me to concentrate at night if she also needs to do so. Living with a close friend is bad for productivity because if you're both home at the same time you'll inevitably spend some time talking or hanging out. I think if my girlfriend was not also in graduate school this would be a very bad setup for productivity. Happiness however is great in this configuration as I'm often near two people I care a lot about, who are both respectful and responsible. It's the quality social experience of the second setup where I had a lot of roommates, without the unpredictability of chatter and music late into the night. In other words, it's for the most part a pretty good average between living alone and living with a group.

I'm a 97% introvert male 22 year old. I've lived with a number of different roommates at work sites and I am living with my parents right now. Living alone would have been preferable in every case. I might enjoy living in an EA or rationalist household, though.

My parents think that I don't work at all, and I prefer to keep it that way, at least, until I achieve some measure of financial success.

I'm an introvert from Barranquilla, a forgettable town near the Atlantic coast of Colombia. At age 26 I finally managed to move out from my parents' house to Bogotá, the capital city. In half a year I was able to get a nice apartment with two other friends. Life there involved a rotating cast of friends who also needed to leave their parents but eventually moved on with their lives. I've been happier with my friends than I ever was with my parents. But some days have been happier than others, and some friends have been better company than others.

I started living alone, then with 3 other friends (ran into problems in 3 - 4 months) and now with only 1 other friend.

My current flat-mate is a reasonable person, not much chit-chat but a cat helped to warm the intra-house athmosphere.

Before this, we lived in a really beautiful house (nice terrace, BBQ potential etc) but the whole thing went sour when one person decided to change his lifestyle in a couple of days. It certainly wasn't fun, but the house was nice. We all had large space to ourselves, but with only 2 people a smaller house still gives enough space per person.

When I lived completely alone, I slacked and became productive in a cyclic pattern, upping productivity come midterm times, slacking at the ends of exams etc.

In all those times (except a few months in a tense house last year) I had weekly visitors, a trio of people plus whomever else I know occasionaly. I really like visitors, but this whole series of living "at my home" made me a kind of recluse. I'd rather have people in the house, rather than go out to meet them.

I'd love to try out the kind of environment Vika talked about, a rationalist house sounds like a pretty nice place to change things about myself with the help of socially helpful people having (hopefully) less than average inferential distances between.

I'm trying to answer this, but I can't help feeling like is overly arbitrary. I've lived with family, but which family? I've lived alone, but how alone? I might have lived with friends, or not, how do you define "friend"? What about living situations that are not covered by those categories, such as living with a lover, or living with coworkers?

This question seems meaningless to me without a lot more specificity.
