You can now write Less Wrong comments that contain polls! John Simon picked up and finished some code I had written back in 2010 but never finished, and our admins Wesley Moore and Matt Fallshaw have deployed it. You can use it right now, so let's give it some testing here in this thread.

The polls work through the existing Markdown comment formatting, similar to the syntax used for links. Full documentation is in the wiki; the short version is that you can write comments like this:

What is your favorite color? [poll]{Red}{Green}{Blue}{Other}

How long has it been your favorite color, in years? [poll:number]

Red is a nice color [poll:Agree....Disagree]

Will your favorite color change? [poll:probability]

To see the results of the poll, you have to vote (you can leave questions blank if you want). The results include a link to the raw poll data, including the usernames of people who submitted votes with the "Vote anonymously" box unchecked. After you submit the comment, if you go back and edit your comment all those poll tags will have turned into [pollid:123]. You can edit the rest of the comment without resetting the poll, but you can't change the options.

It works right now, but it's also new and could be buggy. Let's give it some testing; what have you always wanted to know about Less Wrongers?

Which poll answer will receive the largest number of responses? [pollid:38]

I love this poll
2Unnamed
After one month and 120 responses, I'm considering this poll closed. The results are: 1) The third one: 21% 2) The fifth one: 15% 3) The second one: 14% 4) The first one: 32% 5) The fourth one: 18% A chi-squared test says that these results are non-uniform, with a p-value of 0.02. The correct answer, #5 "the fourth one", was chosen by 18% of respondents. The most common answer was #4, "the first one". This poll idea was taken from a gamefaqs poll which was linked on LW last year. The results of that poll (which had a much larger sample size) were: 1) The third one: 17% 2) The first one: 24% 3) The last one: 21% 4) The second one: 26% 5) The fourth one: 11% My hypothesis about that poll was: That hypothesis predicts that the most common responses on the LW poll would be the level 1 response, #4 "the first one", and the level 2 response, #5 "the fourth one". The data provide partial confirmation of this hypothesis; in terms of levels the most common responses to the LW poll were: 32% Level 1 (#4 "the first one") 21% Level 0 (#1 "the third one") 18% Level 2 (#5 "the fourth one") 15% Level 3 (#2 "the fifth one") 14% Level 4 (#3 "the second one") And for the gamefaqs poll: 26% Level 2 (#4 "the second one") 24% Level 1 (#2 "the first one") 21% Level 4 (#3 "the last one") 17% Level 0 (#1 "the third one") 11% Level 3 (#5 "the fourth one")

Some people don't pick very good schelling points.

Great features ! Thanks and congrats to those who made it happen.

One suggestion : you can't see the result until you voted, I guess it's not to bias/anchor the answer, but then it would be nice to add an option "I don't plan to vote, let me see the results", so someone who doesn't want to vote for any reason can still access the outcome. Or else, there is a risk of people not wanting to vote but wanting to see the outcome will vote "at random" and skew the result.

In the meantime, the effect can be simulated by proper selection of options. Example:

Excluding the ponies (which I didn't vote on, because I am one of sixteen people remaining on the Internet who doesn't pony yet), this is the earliest radio poll where the sum of the numbers in the column matches the "Total" number at the bottom.

This is a problem. Ideally there would be a separate button next to the "vote" button (a forum that I read has that feature, with the button labeled "View Results (Null Vote)"). Second-best would be to allow people to submit a blank vote (which is not as good, since it's not obvious to people that they have that option), but it currently does not work that way (even though the OP seems to say that it does).

A function to automatically compute the averages should be implemented.
3Luke_A_Somers
awk is made for this, but it took me a few minutes to whip this up in java. I figured if numeric polls are used in the future, this can be used as a code-base. The indentation isn't coming through, but any IDE will fix that for you. This doesn't work on arbitrary numeric entry polls, but for those, you can gather the statistics as you go along, putting it in the GATHER loop EDITED to fix serious bug. usage: paste this into PollStat.java, compile it. then run java PollStat < poll.csv.txt So far, the winners are endoself and army1987. I wasn't far off. ~~~~~ import java.io.*; import java.util.*; public class PollStat { public static void main(String[] args) { try { BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); String line = br.readLine(); int[] counts = new int[12]; // PUT NUMBER OF POLL OPTIONS HERE int end, begin; int linen = 0; while (line != null && line.charAt(0) == '#') { line = br.readLine(); linen++; } while (line != null) { // GATHER LOOP linen++; end = line.lastIndexOf("\",\""); begin = line.lastIndexOf("\",\"", end-1); try { line = line.substring(begin+3, end); } catch (Exception e) { System.out.println("At line number "+linen+":"); e.printStackTrace(); System.exit(1); } Integer c = Integer.parseInt(line); counts[c]++; // For arbitrary numeric responses, don't use counts. // just continuously gather your statistics. Alternately, make a list of Doubles or something. line = br.readLine(); } br.close(); int total = 0; int resp = 0; int[] numbers = new int[]{100, 64, 41, 26, 17, 11, 7, 4, 3, 2, 1, 0}; // PUT POLL OPTIONS HERE for (int i = 0; i < c.length; i++) { System.out.println(numbers[i]+": "+counts[i]); total += numbers[i] * counts[i]; resp += counts[i]; } System.out

Not really -- if you check out the wiki page this type of poll is meant for discrete options, not for numbers or probabilities. For probabilities the "poll:probability" type should be used, which does automatically compute averages and medians.

Or UDT. Or CDT. Or EDT.
0A1987dM
Dunno... If you treat it as a zero-sum game (i.e. you don't only want your answer to be close to 80% of the average answer, but you also want other people's answers to be far from it) it's not obvious to me that you should vote 0.
3wedrifid
I was granting for the purpose of responding that loup-vailant's clear assumption that normal game theory principles apply---each agent is interested only in the payoffs to itself to the exclusion of all else and the payoffs are such that it gets 0 for being wrong and >0 for being right. It so happens that my own actual response (100%) doesn't conform to those assumptions. In fact my original reply to: ... was "No", and my original reply to loup-vaillant pontificated about the complete lack of payoff to any of the radio buttons. However I abandoned that point because the point about it not mattering whether the other guy is using CDT or TDT actually matters (somewhat). In this game (ie. with an actual assumed payoff for correct and no negative payoff for other's success) the Nash equilibrium (and the outcome that a group of all CDT agents would pick) also happens to be pareto optimal. In fact, it outright gives the maximum possible payoff to every individual. Even inferior decision theories can pull that off.
2Luke_A_Somers
Yes, but whichever decision theory you're using, you need to be ready for the few people voted for 100. Someone's going to do something to ruin it for everyone.

0A1987dM
(Or even it remembering whether you chose to vote non-anonymously in the last poll you took.)

Oooh great idea. Bugs / Suggestions:

  1. The answers are transformed into this tiny little poll code with a poll id, so I assume it's being saved to a database. However, the questions are not being saved with them. I can edit my question after the poll has been answered. This may result in some pranks later where you ask some obvious question like "does the earth revolve around the sun" or whatever and everyone answers "yes" and then you can change your question to "are you a Scientologist?" and you will see everyone's votes saying "yes" to that. Much more malicious changes are possible, of course. Also, if the questions aren't stored in the database with the answers, you won't have as many options later for doing cool things with your database full of polls.

  2. The code: [Poll] does not work because it's upper case, but this is not an obvious reason for poll failure, so one may end up wasting lots of time trying to figure it out or make annoying requests for support. Making this case insensitive is probably a good idea.

  3. The poll seems designed for very short answers. My elitism poll results look bad for that reason.

6Kindly
Feature, not bug.

BUG: The display of the data for the multiple-choice polls seems to reset at some point, though I can still see the complete raw data when clicking at them... e.g. right now, though 68 people have voted for the "best pony", at the display I only see the choice of the 68th person (Applejack) having a single vote, and all the other choices are falsely at zero.

Similar things with other polls.

9jimrandomh
Confirmed. The issue is in an interaction between the polling code and Reddit's custom ORM which causes vote-totals to be cached, but not persisted to the database correctly. I have a fix, which I'm testing now. All polls created before the fix is applied will be affected; it'll be possible to restore them, but it'd take some work which isn't a priority for me.

To anyone thinking this is not random, with 42 votes in: * The p-value is 0.895 (this is the probability of seeing at least this much non-randomness, assuming a uniform distribution) * The entropy is 2.302bits instead of log(5) = 2.322bits, for 0.02bits KL-distance (this is the number of bits you lose for encoding one of these votes as if it was random) If you think you see a pattern here, you should either see a doctor or a statistician.

Looks like we're better at randomness than the rest of the population. If I asked random people for a random number from 1 to 10, I wouldn't be surprised to see substantially less than 3.322 bits of entropy per number (e.g., many more than 10% of the people choosing 7).

After one month and 118 responses, I'm considering this poll closed. The results are: 1) 17% 2) 21% 3) 20% 4) 24% 5) 18% A chi-squared test says that these results do not differ significantly from uniform random responding, with a p-value of 0.78. The main reason why I ran this poll was because I thought it might have implications for the trickier poll above. It is interesting the option #4 was the most common response in this poll, that poll, and the gamefaqs poll which that poll was based on. #4 may seem especially random, and some respondents in the other polls may have just been trying to answer at random. But this poll ended up not providing much information about that; to test it we'd need a larger sample size, and preferably a poll where respondents did not use external sources of randomness.

Question: what's a reasonable prior over the probability distribution of poll answers? Because I downloaded the raw data, and it says: 1. 15 2. 22 3. 21 4. 24 5. 18 ...and I'm not sure what would constitute reasonable priors for the uniform distribution hypothesis versus the "aversion toward First Answer" hypothesis versus the "aversion toward First Answer and Fifth Answer" hypothesis.
6Kindly
My own feelings on the matter are that if you don't know what prior to have, compute worst-case bounds. In this case, the model that maximizes the probability of seeing this data is that each answer is 15% likely to be 1, 22% likely to be 2, 21% likely to be 3, 24% likely to be 4, and 18% likely to be 5. We can compute the probability of seeing this data under this model, and also under the "all answers are equally likely" model, and conclude that our worst-case model makes us only 3.61 times as likely to see this data. In particular, any other hypothesis you might have can only receive this little evidence, relative to the uniform distribution hypothesis; and I believe in close-to-uniformity enough that I'm not going to be swayed by what is fewer than 2 bits of evidence.
2RobinZ
Thanks! I didn't think of that particular brainhack - I'll be sure to use it in the future.
5othercriteria
Your question is confused. The uniform distribution hypothesis only requires that the (assumed infinite) population picks the answers independently with equal probability. Under this hypothesis, the observed poll answers (for a fixed number of respondents) will follow a multinomial distribution with parameters (0.2, 0.2, 0.2, 0.2, 0.2). A typical realization will not have an equal number of respondents giving each answer, although asymptotically the empirical frequencies will converge to equality. Anyways, as a Bayesian, the better question is what should my posterior belief about the response probabilities be after running the poll and updating off the answers? The canonical way to do this would be to put a Dirichlet prior over the response probabilities. By the miracle of conjugacy, your posterior distribution will itself by a (generally different) Dirichlet distribution. By taking the expectation of indicator variables like I{"probability of First Answer under 0.2"} under the posterior, you can figure out what degree of belief you must give to statements like "respondents have an aversion toward First Answer".
4RobinZ
That makes sense - I had imagined doing something similar, but I had never heard of Dirichlet priors.
3othercriteria
Happy this helped. The Dirichlet-multinomial model gets relatively little attention because it adds nothing really new to the beta-binomial model for polls with just two responses. It's easy to find lots of introductory, chatty introductions to the beta-binomial like this one or this one if you want to learn more...

1Luke_A_Somers
I used the least significant digit on my time-remaining-to-full-charge. And ended up propping up the most populated entry.
1BlazeOrangeDeer
I needed 3 random bits (and threw out any overflow), which I got by checking whether arbitrary words or phrases I thought of had an even or odd number of letters. That's the most random completely mental (heh) way I know of, I wonder if there are others.
3Luke_A_Somers
... you could have done it more-reliably evenly by taking the mod 5 of the phrase/word length.
0A1987dM
Considering that the average word length in English is about five letters, I suspect that'd be quite far from being uniformly distributed.
0Luke_A_Somers
Average is irrelevant. What's relevant is the standard deviation. Since standard deviation goes as the square root of the number of items being added, phrase length for any reasonably-sized phrase, so long as it wasn't a line of poetry, should be pretty evenly distributed.
0A1987dM
It's not obvious to me that it's unbiased. My gut feeling suspects that if I randomly chose a word it'd be more likely to have an odd than an even number of letters.
1mfb
I think this would be even more interesting as "pick at random, without an external source of randomness". Sure you can get random numbers from random.org, your computer or the seconds on your watch (a nice idee), but those just blur the effect of mind-generated random numbers.

After my vote:

Well this is mathematically impossible... My guess is the median isn't properly calculated for even numbers of votes.

Thanks for spotting this! I looked into it, and it seems to be double-counting the most recent result when computing the median. It's an order-of-initialization issue; it thinks it's getting all the results except the new one, adding it, then taking the median, but it's actually getting a list of all the results. The fix is straightforward; I'll email the admins to apply it.

Specifying a lower and upper bound on the input should be required.

1ema

2siodine
It won't prevent trolling but it will minimize its effects. As it stands, you can input numbers like 1e+19 which will seriously throw off the mean. If trolls can only give the highest or lowest reasonable bound then they're not going to have much of an effect individually and that makes going through the effort to troll less worthwhile.
2Kawoomba
Not necessarily: Votes: 12 and 75 Mean: 43.5 Median (upper median): 75 While the standard e.g. wolfram alpha definition (which isn't normative) of the median would be 43.5 as well, it is an accepted practice (in plenty of CS grad classes, at least) to have the median guaranteed to be an element of the sample, normally the upper median is then chosen simply as "median". Hence the wiki definition having the qualifier "usual". In fact, I was surprised that the median is strictly speaking not guaranteed to be an element of the set, using the majority mathematical definition. So, not so much an error as a lazy CS convention ...

This is the sample poll from the article (just a straight copy-paste). These aren't exciting questions, so you should ask some that are!

While simulating this with the current poll structure is possible, it quickly becomes cumbersome with an increased number of options; the number of options in the poll would be two to the power of the number of choices.

Set theorists sometimes remark that there are only very few natural numbers. I think this can be made more quantitative: Based on observations of their blackboard drawings and accompanying explanations, my current best estimate is that there are about five to ten.

You don't need to use infinities to make the mean meaningless: giving answers such as 1e100 will suffice. On the other hand, NANs are traditionally just disregarded when computing means (i.e., the mean of 1, 2, 3 and NAN is taken to be 2) -- essentially they would amount to a blank vote.

MP did not want it to accept either of those things; the notation used suggests "the largest integer less than or equal to infinity", which doesn't exist.

The results so far (only showing answers with > 1 responder): 11 "0.0" 8 "-1.0" 7 "2147483647.0" 5 "3.0" 4 "42.0" 4 "1e+19" 3 "9.0" 3 "8.0" 3 "1.0" 2 "666.0" 2 "32767.0" 2 "24.0" 2 "2.0" 2 "1e+17" To regenerate this, run grep -v "#" poll.csv | awk -F , '{ print $3 }' | sort | uniq -c | sort -nr. I'm not surprised by the number of votes for 2^31-1. It was the first number to pop into my head when I saw the poll.

How awesome is this new feature?

So according to the raw data, 100 people voted, but what I see displayed is 3 votes for answer 4 of 5, one for 5 of 5, and no total.
6Kindly
The "no total" part is independent of the bug -- it seems that scale polls just don't report totals or percentages. (They probably should.)

Minimize the expected square of the distance between your answer and 80% of the mean of the answers chosen: [pollid:9]

Red is a nice [pollid:18]

This is great and I upvoted it, but being meta I think it should be in Discussion.

Awesome! But since we're stress-testing it, let's try doing things wrong.

First thing that I noticed is that it doesn't let you post if there's a poll error. That's great! ... except it doesn't respect four spaces to put something in code format, so I can't easily tell you what I tried and what failed. Putting tests in their own comments to make it more obvious when something passes.

[edit]Oops, this also floods recent comments.

Trying to do a poll with only one option fails gracefully. Example: What kind of book did you read last? [poll]{a book}

Modifying the number of periods modifies the number of options available: [pollid:12]

|poll:True............False|

One period is well-defined: Nope. |poll:True.False| throws an "invalid poll type" error.

What about leaving off one of the names? |poll:True...| throws an "invalid poll type" error as well.

Polls are stored by their id, which makes it so they can't be edited after the fact. (Probably wise.) But what happens when you refer to an old poll by its id? This is |pollid:10|, which refers to the poll from this comment. [pollid:10] What about a future poll? [pollid:999999]

Trying to put two kinds of polls together: How many bugs will I find? [pollid:11] The code for that was |poll:number|{all of them}{none of them}, with the pipes replaced by square brackets. It looks like the interior poll type takes precedence, which is probably what should happen, but it might be better to complain instead.

What use is the mean if anyone can just do something like this?

Yeah, scrap the mean, and show the 1st and 3rd quartile in addition to the median.

Total:25, but adding up the votes for each option gives 24.
3Vaniver
Fascinating, I got two and two (total 33), and after refreshing I see the poll text but it won't let me vote, because I already voted. Also, I think it's sort of amusing that this is the only thing I found that looks like a serious bug to me, but it has the least upvotes of my tests.
0khafra
Less explanation of what exactly you were testing, so the fluency bias kicked in.

I voted in this poll, and after reloading the page, I don't see the results. Sensibly, it won't let me vote again, but now I'm stuck with the survey form. I did see the results immediately after voting.

How many Quality Adjusted Life Years do you estimate you have left? [pollid:43] Include whatever uploads, uplifts, descendant entities, etc. you deem to still be "you"; time spent in a deanimation vault counts as 0 QALYs.

6TheOtherDave
Should I do a weighted sum over descendant entities I deem fractionally me, or just over entities I deem "me"?
2Richard_Kennaway
However you choose to calculate it, that's your estimate of remaining QALY's. For descendant entities you deem fully "you", but with fractional chances of existing, see my reply to Luke.
2TheOtherDave
(nods) Saw that, makes sense. Just so you know, at least one "more" answer reflects, not a confident prediction that the answerer will live more than a millenium, nor a two-order-of-magnitude increase in quality of life, but a willingness to identify fractionally with billions of living people.
6Luke_A_Somers
How to aggregate across the distribution of possibilities? Average? Median? Most likely range? I'm 33, so it wouldn't take too much life extension to get me to 133, but a fair amount... I'd rate the probabilities as roughly 40%, 30%, 10%, 20%. So, each of the three answers is different.
4Richard_Kennaway
The most likely range. I'd rather this wasn't skewed by people putting down "more" just because they anticipate a tiny probability of a vast lifetime, but failing that expect to be dead as usual before very long.
2thomblake
I don't see how to correct for that.
1Richard_Kennaway
The bug concerning reporting of results is still present: currently the counts for the four categories are displayed as 9, 0, 0, 0, with a total of 39. According to the downloaded data, the counts are 28, 4, 1, 6 = 39.

[This comment is no longer endorsed by its author]Reply

Is there any way to embed polls into the body of an Article/Discussion post? Or does it have to be in comments?

0jimrandomh
Currently it has to be in comments. Since comments and articles have entirely different markup and formatting systems (comments use Markdown, articles use constrained HTML), supporting them in both places at once is nontrivial.
0gwern
But the Markdown is converted to HTML in the end... As a workaround: Could I make a poll as a comment, copy the HTML of a non-voted-upon version of the comment, and insert it into the raw HTML of an article? And then delete the original comment?
0jimrandomh
There's a bit more to it than HTML, though - the submission and results display use some Javascript. You might be able to hack an alternative without Javascript, but hitting "submit" would take you to a broken page, rather than replacing the poll with the results in-place.
0gwern
Oh. Too bad then.

Does this poll work? [pollid:97]

Did you enjoy this poll? [pollid:98]

What was the answer to your previous question? [pollid:99]

One common and annoying failure mode in writing polls is omitting options. This can be mitigated by including an extra "Other" option. We could make this automatic and mandatory, adding that option to all polls automatically. The upside is that people couldn't forget or decline to include the Other option when it's appropriate; the downside is that they can't adjust its wording or leave it out when the options are truly exhaustive.

Should multiple-choice polls have an Other option added automatically? [pollid:68]

If someone wrote the code to make the inclusion of an "Other" option a default, opt-out behavior of LW polls, I would not object if that code were added.

1NancyLebovitz
I would even be in favor of it.
0Fyrius
Seconded.

Perhaps we do need some explicit guidelines about the conduct of polls after all, beyond "don't be an asshole". Something about employing neutral point of view, not using a poll for purposes other than conducting a bona fide poll, and making a serious attempt to design it to obtain unbiased data. I had expected this to be obvious, but it seems not.

I don't know if it's specifically addressed anywhere in the Terms of Use, but free use of polls can have some very hurtful results; it might be helpful to somewhere post a guide to what type of polls are appropriate and tolerated.

Can you be more specific about what you mean?

0MaoShan
See my example poll in answer to wedifrid. Hopefully nobody thinks I was being serious about the poll.

This is an especially good point because you're currently able to change the question after the results are in, allowing you to prank the poll takers by making their answers seem to support anything you feel like.

1Epiphany
Here's one: What if someone takes a poll asking if they should kill themselves? People could write "yes" in the comments, but they can select "yes" in a poll anonymously. This may lead to more brutal answers to questions. The questions will be limited to whatever the poll creator types in, but that doesn't mean everyone will use common sense while creating their polls. You may argue "they can already use comments as a polling system using karma" but I would then argue "okay, MaoShan still has a point, and it applies to karma, too." Also

Upvote this comment and downvote the karma sink if you think I should not kill myself. :-)

(Edited to add smiley per Poe's law, especially in case someone sees this comment without seeing the parent first.)

[-]scav140
  1. Most of the commenters here refrain from being antisocial dicks. There's no reason to believe anonymous polling will change that.

  2. Anyone actually making life-or-death decisions on the basis of an internet forum poll has a non-trivial chance of being selected out of the gene pool for related reasons.

  3. Sometimes you want or can accept brutal answers.

  4. Individual responsibility. You can't legislate for or even concern-troll people into having common sense, even assuming common sense is a well-defined and useful property.

1Epiphany
Another thought: Just because a person asking people on the internet whether they should kill themselves isn't likely to survive in any case, this does not mean that LessWrong wouldn't be sued if said person posted a poll and it resulted in their death. For whatever reason, the US legal system has been known to grant large sums of money to people who are harmed by things that many consider inadvisable or "no-brainers".

I suspect people would react against people asking that regardless of whether they include radio buttons. If I recall there has even been drama surrounding making observations about a former member suiciding. I'd be somewhat surprised if someone asking this question directly did not prompt that comment to be banned. No, I haven't observed common sense to universally constrain posting behavior in general. However explicit polls don't strike me as sufficiently different or more powerful than regular comments, (inherently anonymous) votes and private messages that a move from informal expectations that people don't behave like @#%$s need be changed to a formal "Terms of Use".

Explain how not to be an asshole?

And I was hoping to extract your moral theory from you.
0Richard_Kennaway
I don't see this as anything to do with moral theory. It's pretty much general currency what constitutes being an asshole. I've seen it set out in umpteen comment policies on blogs, which often explicitly summarise it as "don't be an asshole", or even "don't be an asshole -- but you knew that already".
-2Eugine_Nier
I don't understand what you mean here. Is your concept of moral theory only something for thought experiments involving Omega but to abstract to apply to day-to-day life?
0Richard_Kennaway
No. I mean it in the same sense that we do not need to have a discussion of moral theory in order to agree on what actions we are talking about, when we talk about theft. We don't even need to have a discussion of moral theory to agree that we'd rather people didn't behave that way.
0MaoShan
That flies in the face of many of the helpful articles I've read here on LessWrong. I would offer to write the "Rationalist's Guide to Not Being an Asshole", but obviously, I'm not qualified. ...because I'm not a good enough Rationalist. ;)
