Surveyed. Having everyone participate in a Prisoner's Dillema is extremely ingenious.

Edit: Hey, guys, stop upvoting this! You have already falsified my answer to survey's karma question by an order of magnitude!

Edit much later: The lesswrong community is now proved evil.

Edit much more later: Bwahaha, I expected that... Thanks for the karma and stuff...

Taken. It was relatively quick; the questions were easy. Thanks for improving the survey!

Two notes: The question about mental illness has no "None" answers; thus you cannot distinguish between people who had none, and people who didn't answer the question. The question about income did not make clear whether it's pre-tax or post-tax.

Are you planning to do any analysis on what traits are associated with defection? That could get ugly fast.

(I took the survey)

I took the survey. My apologies for not doing so in every previous year I've been here, and for not finding time for the extra questions this year.

The race question should probably use checkboxes (2^N answers) rather than radio boxes (N answers). Biracial people aren't that uncommon.

Living "with family" is slightly ambiguous; I almost selected it instead of "with partner/spouse" since our kids are living with us, but I suspected that wasn't the intended meaning.

dude, no "jewish" religious background? seems like a serious omission unless my priors are all screwed up.

Notes taken while I answered.

What is your family's religious background, as of the last time your family practiced a religion?

We're Ashkenazi Jews, but AFAIK the last time any ancestor of mine practiced a religion was in my great-grandparents' generation. (And then only because I knew only one of them personallyh, so it's reasonable to assume at least one of the others could have been religious.) I get that every human is descended from religious ones, but conflating this datapoint with someone whose actual parents practiced a religion once seems wrong.

Probability

For some of these my confidence was so low that I didn't answer. For some questions, there are also semantic quibbles that would affect the answer:

• Supernatural: AFAIK there is no agreed-on definition of "supernatural" events other than "physically impossible" ones which of course have a probability of 0 (epsilon). OTOH, if you specify "events that the average human observer would use the word 'supernatural' to describe", the probability is very high.
• Anti-Agathics: what counts as reaching an age of 1000 years? Humans with a few patched organs and genes? Cyborgs? Uploads with 1000 subjective years of experience?
• Simulation: this is complicated by ontological differences: whether, when universe A is simulated in universe B, this somehow contributes to B's "realness" measure, or actually creates B. Is existence of a universe a binary predicate? I answered as if it is.

Type of global catastrophic risk: although I chose the most probable, there wasn't a large difference in estimated probability for the top few leading dangers.

about how often do you read or hear about another plausible-seeming technique

At first I thought "every few days". But then I realized these techniques almost never work out or are unsupported by evidence, and so it would be wrong to call them plausible-seeming. So I recalibrated and answered much more rarely.

Then I saw the next questions asked how often I tried the technique and how often it actually worked. But I already choose not to try them most of the time because I expect not to succeed. So I let my previous answer stand. I hope this was as intended.

CFAR bonus questions:

You are a certain kind of person

Are these questions claiming that I, DanArmak, am this kind of person who can change; or that everyone can change? The answers would be very different. I assumed the latter, but it would be nice to have confirmation.

Other nitpicks: a certain kind on which dimension? Some aspects of personality are much harder to change than others.

What is the measure of "true" change? By the means available to us today, we can't change into truly nonhuman intelligences, so does that mean our "kind" cannot be changed? And the answers to the questions will change over time as technology creates new more effective interventions.

And: does "basic things" mean "fundamental things" or "minor insignificant things"? Normally I would assume "fundamental things", but then it seems identical to the previous question.

On a personal note, this set of questions struck me as incompatible after answering the previous sets. They seem to deliberately probe my irrational biases and cached beliefs, and I felt I couldn't answer them while I was deliberately thinking reflectively and asking myself why I believed the answers I was giving.

How would you describe your opinion on immigration?

The politics of immigration in Israel are totally different from those of the US (and I expect this holds for many other countries too in their different ways). I didn't answer because I was afraid of biasing the poll, and it would have been nice to get more guidance in the question.

Surveyed.

The occupation thing could have been a checkbox, for us who are e.g. both students and doing for-profit work.

The income question could have used a clarification of whether it was pre- or post-tax. (I assumed pre-.)

I found myself geuinely confused by the question "You are a certain kind of person, and there's not much that can be done either way to really change that" - not by the general vagueness of the statement (which I assume is all part of the fun) but by a very specific issue, the word "you". Is it "you" as in me? Or "you" as in "one", i.e. a hypothetical person essentially referring to everyone? I interpreted it the first way then changed my mind after reading the subsequent questions which seemed to be more clearly using it the second way.

Took the survey. Can't wait for the results.

Answered the entire survey (except questions for U.S. residents). I can't see why Newcomb's problem is a problem. Getting $1,001,000 by two-boxing is an outcome that just never happens, given Omega's perfect prediction abilities. You should one-box.

done

I worry that I harmed the results by mentioning that I have meditated for cognitive benefit reasons, without a way to note that it wasn't to deal with Akrasia. I wanted to answer truthfully, but at the same time the truthful answer was misleading.

I hereby take part in the tradition and note that the tradition makes the following moot for relatively low levels of karma. You may round off your karma score if you want to be less identifiable. If your karma score is 15000 or above, you may put 15000 if you want to be less identifiable.

Income question: needs to specify individual or household. You may also want to specify sources, such as whether to include government aid, only include income from wages, or separate boxes for different categories of income.

I have done professional survey design and am available to assist with reviewing the phrasing of questions for surveys, here or on other projects.

Surveyed!

Thanks for putting this together.

Perceived flaws:

Percentages are probably not the best way to elicit well-calibrated guesses about very probable or very improbable events. (The difference between 1/1,000 and 1/1,000,000 is a lot bigger in reality than it looks, when you put them both between 0 and 1 on a scale of 0 to 100.)

Computing P(Many Worlds) requires assuming that the phrase "Many Worlds" refers to a specific set of concrete predictions about the nature universe, which admit the possibility of truth or falsity. I tend to disagree with that presumption.

P(Anti-Agathics) seems, from the name, not to be intended to include cryonics, but does seem to include it in the actual text. I predict paradoxical answers in which people give P(Cryonics) > P(Anti-Agathics), even though cryonics is a way of allowing a person alive today to reach the age of 1000 years.

P(Simulation) may or may not actually be a well-defined question. If, as some people are surely visualizing while answering it, there are aliens somewhere hovering over a computer terminal with us running on it, certainly the answer is 'yes'. Whatever the reality, it seems likely to be a lot stranger than that. Eliezer's own "Finale of the Ultimate Meta Mega Crossover" describes a scenario (admittedly fanciful) in which one would be hard pressed to answer the "simulation" question with a simple yes or no.

Took it. It's a good survey with a lot of interesting questions.

Done. There were a few questions that were iffy, but overall I think this year's survey was a significant improvement from previous versions. Thanks Yvain for doing this.

I completed the survey & had to look up the normative ethics choices (again). Also cisgender. I cooperated with the prisoner's dilemma puzzle & estimated that a majority of respondents would also do so, given the modest prize amount.

Also, based on my estimate of a year in Newton's life in last year's survey, I widened my confidence intervals.

Several of these questions are poorly phrased. For instance, the supernatural and god questions, as phrased, imply that the god chance should be less than the chance of supernatural anything existing. However, I think (and would like to be able to express) that there is a very small (0), chance of ghosts or wizards, but only a small (1) chance of there being some sort of intelligent being which created the universe-for instance, the simulation hypothesis, which I would consider a subset of the god hypothesis.

Took the survey, including all questions. Hope it is not discarded for contradictory elements.

Took it. Comments:

• Hopefully you have a way to filter out accidental duplicates (i.e. a hidden random ID field or some such), because I submitted the form by accident several times while filling it out. (I was doing it from my phone, and basically any slightly missed touch on the UI resulted in accidental submission).

• Multiple choice questions should always have a "none" option of some kind, because once you select a radio button option there's no way to deselect it. Most of them did but not all.

• I answered "God" with a significant probability because the way the definitions is phrased, I would say it includes whoever is running the simulation if the simulation hypothesis is true. I'm sure many people interpreted it differently. I'd suggest making this distinction explicit one way or the other next time.

I'm confused by the CFAR questions, in particular the last four. Are they using you as 'the person filling out this survey' or the general you as in a person? "You can always change basic things about the kind of person you are" sounds like the general you. "You are a certain kind of person, and there's not much that can be done either way to really change that" sounds like the specific you.

Help?

I have taken the survey (and answered, to a good approximation, all the questions).

Note that if you take the survey and comment here immediately after, Yvain can probably identify which survey is yours. If this possibility troubles you, you may wish to delay. On the other hand, empirically it seems that earlier comments get more karma.

I conjecture that more than 5% of entrants will experience a substantial temptation to give SQUEAMISH OSSIFRAGE as their passphrase at the end. The purpose of this paragraph is to remark that (1) if you, the reader, are so tempted then that is evidence that I am right, and (2) if so then giving in to the temptation is probably a bad idea.

Survey taken. The very last question made me laugh out loud. It also proved to me that this is truly my type of community.

Surveyed. Left several questions blank.

Incidentally, while I answered the "akrasia" questions about mental illnesses, therapy, etc. as best I could, it's perhaps worth noting that most of my answers related to a period of my life after suffering traumatic brain injury that significantly impaired my cognitive function, and therefore might be skewing the results... or maybe not, depending on what the questions were trying to get at

I took the survey.

However, this question confused me:

Time in Community How long, in years, have you been in the Overcoming Bias/Less Wrong community? Enter periods less than 1 year in decimal, eg "0.5" for six months (hint: if you've been here since the start of the community in November 2007, put 6 years)"

(emphasis mine)

The wording confused me; I almost put "6 years" instead of "6" because of it.

Also, I was sorely tempted to respond that I do not read instructions and am going to ruin everything, and then answer the rest of that section, including the test question, correctly. I successfully resisted that temptation, of which fact I am proud.

Taken, Answering all questions. I answered the last question (Co-operate or Defect) only after coming back and reading the comments, but I think I forgot to put in my passphrase so it doesn't really matter.

Surveyed.

Nice to see the reactionaries got their bone thrown to them on the politics section.

Finally decided to register for an account here. That reward structure will be fun to watch.

Surveyed. Put a humorous pair of Lojban lujvo as a passphrase. I cooperated, knowing that regardless, I was unlikely to win no matter what strategy I pursued, and that priming myself by forcing myself to cooperate now would possibly make me unknowingly want to cooperate in the future to my benefit.

Survey Taken.

I can't wait to see the Cooperate/Defect ratio. I, for one, chose to cooperate.

Done. I'm glad there was nothing about Schrodinger this time around.

Oh wow, you really cut down on the extra credit questions this time- no links to external tests! Not sure if I like that or not; in particular, now we only have one IQ source to look at. But oh well.

(I took the survey.)

I have never posted on LW before, but this seems like a fine first time to do so.

I am really very curious to see the results of the real world cooperate/defect choice at the bottom of the test.

Survey taken.

I found the Europe question awesome because I, incredibly luckily, had checked Europe's total population for a Fermi estimate just yesterday, so I got to feel like a high accuracy, highly calibrated badass. Of course, that also means it's not good data for things that I learned greater than ~1 day ago.

Surveyed.

Made an account here to comment that I filled out the survey, and to make future participation more likely.

Surveyed.

The IQ question should, like with the SAT/ACT, make it clear you should leave it blank if you've not been tested. And the same with the follow-up in calibration.

Survey completed in full. Begging for karma as per ancient custom.

I choose DEFECT because presumably the money is coming out of CFAR's pocket and I assume they can use the money better than whichever random person wins the raffle. If I win, I commit to requesting it be given as an anonymous donation to CFAR.

EDIT: Having been persuaded my Yvain and Vaniver, I reverse my position and intend to spend the prize on myself. Unfortunately I've already defected and now it's too late to not be an asshole! Sorry about that. Only the slightly higher chance of winning can soothe my feelings of guilt.

I took the survey a few days ago and ran into trouble trying to answer the IQ test-related questions (IQ/SAT/ACT/etc.) because I would have to dig around for the answers to those questions and that required more effort than I wanted to spend on a survey.

The instructions for entering percents was also a bit confusing.

Other than that, the survey was well designed. I really appreciated how clear you were about where it was OK to stop and that it was fine to leave things blank.

Done. I hate to get karma without posting something insightful, so here's a song about how we didn't land on the moon.

I wanted an ADBOC answer to the HBD question. Lacking that, I answered the question about the belief (regardless of whether I endorse policies that people with the same belief typically endorse -- like I did for the AGW question), but given that (unlike the AGW question) it was in the politics section and that it mentioned a movement, I felt a bit uncomfortable doing that. Also, I interpreted "we" in the Great Stagnation question as "American", given that that's what the cited Wikipedia article says.

In the income question I only counted my PhD scholarship after taxes, and not the "reimbursement" of travel expenses (which often exceed the amount I actually spend while travelling) nor the private tutoring I've very occasionally done (I kind-of consider the money a gift in exchange of a favour).

I rounded my top-level contributions to Main and Discussion down to zero.

Took the survey. Note: "average" is not a very precise term. For one, "average person" is probably a mediocre stand-in for "typical person" (since there isn't actually a commonly accepted way to take averages of people). Furthermore, questions like "How long, in approximate number of minutes, do you spend on Less Wrong in the average day?" are actually highly ambiguous. The arithmetic mean of times that I spend on Less Wrong over days is substantially different from the median time.

Surveyed.

Also, spoiler: the reward is too small and unlikely for me to bother thinking through the ethics of defecting; in particular, I'm fairly insensitive to the multiplier for defecting at this price point. (Morality through indecisiveness?)

Taken, answering all of the questions I was capable of answering. I will be very interested to see the results on some of the new questions. (The shifts on existing questions could also be interesting, but I don't expect much to change.)

Survey taken.

It seems that I only comment here when I take the survey and remain a lurker otherwise.

(Survey taken)

Took the survey.

I'm interested in seeing what sort of interventions ended up working for people with akrasia.

I took the survey.

I, like many others, was very amused at the structure of the MONETARY AWARD.

I'm not sure it was an advisable move, though. There's an ongoing argument about the effect of rewards on intrinsic motivation. But few argue that incentives don't tend to incentivise the behaviour they reward, rather than the behaviour the rewarder would like to incentivise. In this instance, the structure of the reward appears to incentivise multiple submissions, which I'm pretty sure is not something we want to happen more.

In some contexts you could rely on most of the participants not understanding how to 'game' a reward system. Here, not so much, particularly since we'd expect the participants to know more game theory than a random sample of the population, and the survey even cues such participants to think about game theory just before they submit their response. Similarly, the expectation value of gaming the system is so low that one might hope people wouldn't bother - but again, this audience is likely to have a very high proportion of people who like playing games to win in ways that exercise their intelligence, regardless of monetary reward.

So I predict there will be substantially more multiple submissions this time compared to years with no monetary reward.

I'm not sure how to robustly detect this, though: all the simple techniques I know of are thwarted by using a Google Form. If the prediction is true, we'd expect more submissions this year than last year - but that's overdetermined since the survey will be open for longer and we also expect the community to have grown. The number of responses being down would be evidence against the prediction. A lot of duplicate or near-duplicate responses aren't necessarily diagnostic, though a significant increase compared to previous years would be pretty good evidence. The presence of many near-blank entries with very little but the passphrase filled in would also be very good evidence in favour of the prediction.

(I used thinking about this as a way of distracting myself from thinking what the optimal questionnaire-stuffing C/D strategy would be, because I know that if I worked that out I would find it hard to resist implementing it. Now I think about it, this technique - think gamekeeper before you turn poacher - has saved me from all sorts of trouble over my lifespan.)

I was confused by what was meant with supernatural. I mean if you believe you live in a simulation of course things that are not constrained by the physical laws of our universe might occasionally show up in it. Preferred the ontologically basic mental entity formulation of previous polls.

I'm disappointed to see that most of my suggestions weren't used.

Took the survey. Surprisingly short.

Survey Taken

Congratulations for putting the dilemma to test. That was the hardest survey I've taken since the 2012 one.

Took the survey and cooperated.

Survey taken. Defected since I'm neutral as to whether the money goes to Yvain or a random survey-taker, but would prefer the money going to me over either of those two.

I've taken the survey.

By the way, nice game at the end. I didn't do the math but it seemed evident that defecting was the logical choice (and by reading the comments below I was right). I cooperated anyway, it just felt right. So, defectors, I probably just made one of you a few hundredths of a cent richer! Lucky you! ;-)

I'm doing the survey while I should be in a lecture, and I just reached the akrasia questions.

I took it.

Survey taken.

Cooperator here.

Taken the survey. Thanks for doing this, Yvain.

Surveyed, requesting free internet points.

I took the survey.

I completed every question on the survey that I could.

Took the survey.

I have taken the survey, also the extra part. Although I was never tested for IQ in professional way and since it was a question in the non-extra part, I assume that most LW readers were. Interesting observation (if true). Maybe it is a nationally dependent thing? This ad-hoc hypothesis can be validated by the survey if only enough people from enough countries take it

I took the survey. Also just realised that my choice of pass phrase was really silly... I was trying to make it easy for myself to remember what the second word would be, but failed to observe that the first word could become public and therefore it would be sensible to choose something that wouldn't be obvious to just about anybody from knowing the first word! Ah well, in the unlikely event that I win the draw, whoever gets in first can have the prize, I guess...

Took it.

Could you add a question asking how many of their donations people gave to non-x-risk EA charities? The EA movement would appreciate the information!

taken. I did the whole thing! it actually wasn't that long.

I took the survey.

I think most of my answers were the same as last year, although I think my estimates have improved a little, and my hours of internet have gone down, both of which I like.

Many of the questions are considerably cleaned up -- much thanks to Yvain and everyone else who helped. It's very good it has sensible responses for gender. And IIRC, the "family's religious background" was tidied up a bit. I wonder if anyone can answer "atheist" as religious background? I hesitated over the response, since the last religious observance I know of for sure was G being brought up catholic, but I honestly think living in a protestant (or at least, anglican) culture is a bigger influence on my parents cultural background, so I answered like that.

I have no idea what's going to happen in the raffle. I answered "cooperate" because I want to encourage cooperating in as many situations as possible, and don't really care about a slightly-increased chance of < $60.

Surveyed. I liked the game.

If there are any naturalistic neopagans reading this, I'm curious how they answered the religion questions.

Taken.

Surveyed.

taken!

Answered them all as best I could :^)

I left the 'Singularity' question blank because it was I'll-defined - I treated it like a question specifically on the IE, but anyhu, my Priors on that are totally wacky. I expect it to happen, but I have no knowledge of the time at all really.

Surveyed. Is it okay to answer commited theist/pastafarian? :)

Taken for the first time. 'Twas fun.

Surveyed. Thank you.

Took the survey.

I noticed a bunch of people saying that they will donate the money if they win. I find that a surprisingly irrational sentiment for lesswrong. Unless I am missing something, it seems people are ignoring the principle of the fungibility of money. It seems like the more rational thing to do would be to commit to donating 60$ whether or not you win. (If your current wealth level is a factor in your decision, such that you will only donate with the higher wealth level with the prize, then this can be modified to donating whether or not you win if you receive a windfall of 60$ from any source (your grandmother gives a generous birthday present, your coworker takes you out to lunch every day this week, you find money in the street, you get a surprisingly large bonus at work, your stocks increase more then expected etc))

Surveyed.

First survey and comment, and I liked it too! (Including the bonuses, especially the reward question :)

Taken the survey!

I took the survey.

I realized while answering one of the questions that the comments that I make for free karma are one of my main interactions with the LW website.

Survey taken, answered all questions I could. This excluded the IQ question set. I've never taken an IQ test. I've never been offered an IQ test, nor considered taking one. Is that strange? The survey seemed pretty confident that I'd have measured my IQ.

I took the survey! Great set of questions. I felt like it was rather well designed,

It is done.

Short comments:

(Calibration Question) Without checking a source, please give your best guess for the current population of Europe in millions (according to Wikipedia's "Europe" article)

This is ambiguous! While strictly speaking "Europe" defaults to "the continent of Europe" spanning to the Ural, in common parlance "Europe" is used interchangeably with "European Union", similar to how you interpret "American student" in your very survey, a totum pro parte. Stahp with the totums pro parte for calibration questions, I beseech thee! (Of course I wouldn't have minded had I not given the correct answer for the European Union...)

(Akrasia: Elsewhat 1) Have you ever other things to improve your mental functioning?

Has Anyone Really Been Far Even as Decided to Use Even Go Want to do Look More Like?

I took the survey - extra credit and everything!

Suggestion: If you are upvoting people who took the survey, sort comments by "New" first so that late takers get their upvote.

I took the survey as well

Survey taken, all of it!

Thanks Yvain, for all the time and work you put every year into this. Can't wait to see the results!

I completed the survey.

Second time taking the survey. I think a lot of my answers to the probability questions have changed in the last year — I think I've discovered more about myself and my beliefs since the first survey.

I meant to skip some of the extra credit questions (the ones about the changeability of personality in particular), but wound up stuck answering one of them by software glitch on my computer (I couldn't uncheck it entirely, but at least tried to keep it from being noise).

I finished and had fun even if parts of it made me feel dumb (I never thought about that calibration question before and am pretty sure I got it wildly wrong). The monetary reward at the end looks interesting but even in the unlikely case that I won I might have too much trouble claiming any kind of prize right now...

What about being the ultimate defector and submitting multiple times to increase your chances of winning (and screwing up the survey results as a side effect)?

I just realized I forgot a very important question I really want to know the answer to!

"What is your 90% confidence interval for the percent of people you expect to answer 'cooperate' on the prize question?"

I've added this into the survey so that people who take it after this moment can answer. If you've taken the survey already, feel free to record your guess below (if you haven't taken the survey, don't read responses to this comment)

I took the survey.

I was within a factor of 2 on the Europe question, which is pretty good, I think.

As a general rule I "cooperate" on prisoner's dilemmas where the prize is of a trivial size, regardless of my opinion about the incentives and people involved. An interesting experiment might be to take people familiar with the prisoner's dilemma, flip the "cooperate" and "defect" incentives, and see if it makes a difference.

If possible, I'm interested in how unique the passwords were.

I took the survey. Thanks for running it.

Should Muslim be divided into types?

I'm not sure what supernatural means for the more arcane simulation possibilities. I consider it likely that if we're simulated, it's from a universe with different physics.

I would rather see checkboxes for global catastrope, since it's hard to judge likelihood and I think the more interesting question is whether a person thinks any global catastrophe is likely.

Would it be worth having a text box for questions people would like to see on a future survey? I'm guessing that you wouldn't need to tabulate it,-- if you posted all the questions, I bet people here would identify the similar questions and sort them into topics.

Surveyed.

Cool. Survey taken.

Survey complete.

Did the survey. Thanks, Yvain.

Survey taken. Nearly all questions answered, except for the Akrasia ones, since I haven't implemented many formal practices to fight akrasia.

Surveyed.

Surveyed. Amused at the final part. I hope we can look forward to more such fun in the future surveys!

Took the survey.

I've never been IQ tested.

Taken.

I took the whole survey.

Taken!

I've taken the survey.

I have taken the survey, as I have done for the last two years! Free karma now?

Also, I have chosen to cooperaterather than defect was because even though the money technically would stay within the community, I am willing to pay a very small amount of money from EV in order to ensure that LW has a reputation for cooperation. I don't expect to lose more than a few cents worth of expected value, since I expect 1000+ people to do the survey.

Took the survey. I definitely did have an IQ test when I was a kid, but I don't think anyone ever told me the results and if they did I sure don't remember it.

Also, as a scientist I counted my various research techniques as new methods that help make my beliefs more accurate, which means I put something like 2/day for trying them and 1/week for them working. In hindsight I'm guessing this interpretation is not what you meant, and that science in general might count as ONE method altogether.

Taken.

Thanks for running these, I took it. :) Love the prize question.

...I'm way off on the population of Europe, as I expected.

Took the survey.

Survey taken. I defected, because I am normally a staunch advocate of cooperation and the stakes were low enough that it seemed like a fun opportunity to go against my usual inclinations. If I had read the comments first, I would likely have been convinced by some of the cooperation arguments advanced here.

Taken. Quite tickled by the prize question.

Survey taken, can't wait to see the results :-)

Survey taken.

Survey taken

Took survey. Reminded me that I've never had an IQ test; is it worthwhile?

Took the survey. I was unusually confident of an incorrect number for the population of Europe because I looked it up recently, but remembered it wrong.

Guess I learned something, in that I should adjust down my confidence in recalled figures after a few weeks.

Surveyed. Looking forward to the data and analysis, as per every year.

Entered.

Completed survey.

Feedback: I feel like it would be valuable to disambiguate between "I'm planning to have more children in <2years" from "I'd like to someday have kids".

"am I a student?" and "how do I make money?" like separate questions to me. Like student is sort of an occupation, but it's not a way to earn money. I am both a student and self-employed, and about 6 months of the year I do internships = for-profit work.

It would be awesome if Time of LW included both a mean and median time or something, also perhaps a total time spent on it. For me it varies hugely, and I really had no idea what to put. Some weeks I spend many hours on it, other weeks 0.

Delurked and taken (finally); this is my first comment. I'd been wanting to take this survey for a while, but offline matters kept me away until now. At least I got in a good stab at most of the extra credit questions.

I second the following suggestions:

• Clarify the income question on tax status (pre-tax / post-tax / pre-some taxes and post-others) and individual vs. household. I mention the third tax possibility here because some taxes are deducted by the employer, so employees don't see that money in their paychecks. If the question intended is along the lines of "Other than tax refunds, how much money do you / your household receive (that you can use in a budget and could theoretically spend, although some of it may be set aside for further taxes) in a year?", then this matters.
• Add a "None" option to the mental illness question to distinguish between "none" and "didn't answer". Checkboxes would be nice, since mental illnesses can interact with each other, but Yvain has stated that he can't put them in the survey. I will mention this anyway in case checkboxes become viable for future versions of the survey.

I will also make a further suggestion, although I understand that it may be too onerous to implement: have an option to make only part of one's responses private. I mention this because I started by choosing the "public but anonymous" option, but switched to "private" once I got to the point that all my responses together could probably identify me out of the dataset if someone was moderately determined to do so and knew a few specific facts about me.

In my case, making a single extra credit section private (showing it as if I hadn't answered in the public dataset) would have been enough for me to be comfortable putting the remaining responses in the public dataset. That section has data that I don't mind giving Yvain and CFAR, but don't want to leave readily available to potential future agents trying to identify my responses in the dataset. I would prefer to make only the single section private, but I did not have that option available. I am also curious if other people are in the same boat.

Should I win, I precommit to spending the prize on myself, as per Yvain's stated wishes for the prize.

I took the survey.

I took the survey.

This is, incidentally, my first comment on LessWrong. I've lurked for years, and pretty much thought I'll probably stay as a lurker for good. For some reason taking the survey made me want to break my silence.So that's a bonus, I guess.

Survey complete! I answered ALL the questions. ^_^

Survey taken, as always. It sure was well prepared. It's worth starting it for the first option (ruining everything), and continuation is always just one click away...

I took the survey.

Took it.

I definitely gave a finite probability for "God" if "God" defined as a super-intelligent being that created the universe. This is of course quite different from an intervening god who is interested in say, human affairs.

Took. Definitely liked the shorter nature of this one.

Cooperated (I'm OK if the money goes to someone else. The amount is such that I'd ask that it get directly sent elsewhere, anyway.)

Got Europe wrong, but came close. (Not within 10%.)

I should mention that I've taken the survey.

No, I don't read instructions and am going to ruin the survey results for everyone.

snicker

Also, wow, the population of Europe is wildly lower than I thought it was, it's outside my 90% range...

Random math: one way of deciding whether or not to cooperate in the reward question is plot reward versus percentage-UDT-users in the LW community (under the assumption that everyone in that set will do the same thing you do, and everyone else splits 50-50). If that percentage is larger than about 65% (which I'm 70% sure it is), cooperating is superior to defection, but defection actually has the higher maximum expected value - if the entire community chooses randomly, anyway.

...

blink blink

Aw, darn it, I should've flipped a coin...

Edit: No, wait, nevermind, that would halve my expected reward.

Took the survey.

Took the survey. Prisoner's dilemma was a nice addition - would be interesting next year to have 'would you co-operate in a prisoner's dilemma situation' earlier in the survey before the for-stakes version, and compare how often people co-operate in the for-stakes then as compared to this year (also compare across who has taken a LW census before, since this one might bias that a bit).

Took the survey. Yvain, thanks for doing this.

taken.

Done! Phew

Took the survey. Cooperated.

I have taken the survey. Thank you Yvain for running it.

Did the survey.

I did the survey, mostly.

Well that was the most interesting survey I have taken in a long time - looking forward to seeing the results. I was a little concerned at the start, as it seemed like some sort of dating service so the comment 'hang in there - this bit is almost over' was well placed.

Taken and look forward to seeing the results. Thanks for putting this together.

I took the survey, my first, and answered all the questions and extra credit. I did not defect on the monetary reward.

I predict my survey will show me as highly confused. :-)

Surveyed! I noticed that someone said that they cooperated on the prisoner's dilemma problem, so I'll balance the odds and tell you all that I defected. Am curious to see if this will reflect in the karma people give this comment.

Also, I wouldn't do this, but you leave the option open of someone poisoning the well and taking the survey a bunch of times to improve their chance of winning the money. Are you screening for duplicate IP addresses?

I took it, and even did the bonus questions. Yay me!

Took the survey.

Would probably not have defected a year ago, and it would not have been an easy decision for me at that time.

I appear to be getting better at estimating.

I think the IQ questions should probably just be dropped from future tests. A number of people get tested as kids and get crazy numbers and never get tested again (since there's no real point, and people are generally afraid of seeing that number dive, people who get a crazy number are probably less likely to retest than others). That's a charitable explanation for the results in last year's survey, which I didn't take.

I have been surveyed.
