Infrequent Anonymous Cowards Reliable on Wikipedia 264

Posted by samzenpus from the a-visit-from-the-correction-fairy dept.
Hugh Pickens writes "Researchers at Dartmouth University have recently discovered that infrequent anonymous contributors, so called "Good Samaritans," are as reliable as registered users who update constantly and have a reputation to maintain. A graph from page 31 of the group's original paper (pdf file) shows that the quality of contributions of anonymous users goes down as the number of edits increases while quality goes up with the number of edits for registered users."

    Unlike what some users may tell you, many anonymous users contribute content and not vandalize. The quality of the edits per se is all over the place, but this is to be expected, as there is no way a new contributor can know all the nuances of the in-house referencing system [wikimedia.org], or the indications made by the Manual of Style [wikipedia.org]. But they do try.

      I don't think that this is really all that surprising, people that just do one or two edits aren't typically doing it because the have an investment, they are generally doing it because they found an error.

      Some presumably do deface the pages, but I don't find it terribly surprising that somebody that primarily uses wikipedia would be more reliable than somebody that spends most of their time building a reputation. There's just so much more incentive to fix it if you are using it. That isn't to say that named contributers are inherently bad.

To prohibit anonymous editing is actually a perennial proposal [wikipedia.org] which comes up periodically.

      The graph they show is practically meaningless.

      • First, the graph shows that the retention rate for all contributors is below 1%. I find that pretty hard to swallow in the first place, and it makes me doubt that it's based on good data, though I suppose the decimal point could be an error (I'm hoping so).
      • Secondly, the graph shows a continuous line, though the x axis is clearly discrete. Based on the graph, the retention rate for non-registered contributors who have made one edit is about 0.72%; all well and good. How is it that we are given a retention rate for contributors who have made one and a half edits? How is it that we are given a retention rate for contributors who have made no edits? Has any thought at all gone into this?

      The rest of the study may possibly have some good stuff in it, but the incompetence that has gone into this graph leaves me with grave reservations.

      Doing such a study requires checkuser [wikipedia.org] access, which is something only a few people on Wikipedia have. Fortunately, I am one of them. I just sampled ten users out of the new user log [wikipedia.org]. I am assuming a 1:1 mapping between IP and user (that is, that a user made no anonymous edits except with the IP he used to register his account). The number of anonymous edits prior to registeration for each user was:

      A - 0
      B - 0
      C - 0
      D - 2
      E - 0
      F - 0
      G - 0
      H - 0
      I - 0
      J - 0

      In short: most of the people registering accounts had made no edits prior to registering. It's common knowledge on Wikipedia that something like half of all accounts registered never make any edits at all, so this makes sense.

    The graph on page 31 is the retention rate of characters contributed by an editor relative to the total edits by that editor to the article ("The dependent variable is the retention rate, R, of contributions, measured as the percent of characters retained per contribution by each contributor.")

    This metric makes sense if the wiki is new, and most of the edits are adding new content. The metric is virtually meaningless if the wiki is established, and most of the edits by a group of people are vandalism or reverts - people fixing the article will have a lower score by virtue of the fact that they are making the same edit (more or less) over and over again.

    Normally, you'd expect that the more edits a user makes, the more trustworthy he is. If he were vandalizing, he wouldn't make more than a few before being blocked. If he's making hundreds, he should be considered more trust worthy (and have a higher retention rate) than if he's new. The results here show the exact opposite for anonymous users. In short, the methodology is flawed and the results are wrong.

    I fully admire the eagerness of individual contributors, anonymous or not, to improve Wikipedia.

    Unfortunately, not all edits which are good-intended actually contribute to the overall quality. Of course, edits which fix simple things like revert vandalism, fix a typo, update a number etc, are all good. But the rest pose a potential problem. First off, newcomers, while well-intented, simply do not know the way Wikipedia works. They may include unsourced or poorly sourced material, insert a POV without even realising it, piss off another editor by being careless (and thus start an edit war) etc.

    But even those edits which do not break any Wikipedia rules or guidelines still can cause damage, this time much more subtle. The thing is, a (good) Wikipedia article is not just a collection of facts, even if every single fact is relevant, neutral, sourced, and deserves to be in the article. An article is a unified piece of work. It should flow to the reader, not bump. Information must be properly organized and related to each other. A major suffering of Wikipedia is the so-called "contribution creep", where people just keep dumping more and more facts into the article. The result is grossly disproportional coverage of some sections compared to others, a huge overemphasis on bullet-point lists rather than coherent paragraphs, lots of small factoids which while each good on their own right, do not belong together, parts of articles being outdated compared to other parts, and a lot of other problems which make Wikipedia look like a search result by Google rather than a real encyclopedia.

    Early on, Wikipedia's first priority was to fill its databank with stuff, and all contributions (other than those breaking policy) were welcome. Recently, WP is at the stage of more stringent enforcement of policies, as well as guidelines and styleguides. And by all means, that is very important and should be the first priority. But it's not enough to be a good encyclopedia. Making sure everything is neutral, notable, verifiable, attributed, legal, and formatted according to style, is all sub-article tasks, which you apply to a particular sentence, paragraph, or image. But then you have to pause for a moment and look at an article at the big picture. Does it flow smoothly? Are all sections balanced? Are all parts equally updated? Would an average reader get a proportional representation from the article?

    You can easily handle the sub-article problems (those that break a clearcut policy or guideline) contributions from anonymous edits (as well as non-anonymous edits). But "Contribution creep" is biggest problem to the overall article, where there is no clearcut right or wrong. And that's why, no matter how important anonymous edits are to Wikipedia (and they certainly are), the already developed articles should be marked as "revised" and new contributions screened before updating them. Not because of potential vandalism or policy violations (those are easy to fix), but precisely to manage contribution creep and make sure well-intented contributions don't introduce speedbumps to an article and break its coherent organization and flow.

      You have described the dilemma of the Wikipedia editor/administrator.

      There are edits that are obviously unhelpful; there are others that are clearly helpful. But there is a gray area of edits that falls in between, and for which editors' reactions vary a lot.

      A good example is an anonymous/new editor adding unsourced information to a carefully-sourced Featured article. You can't let the information just remain there, as editors have gone through that page, double-checked the citations and validity of the statements, and generally polished the article to have its prose crisp and clean. But you cannot just revert the edit wholesale, as the edit was not done in bad faith. While sometimes the edits can be fixed, there are many times that the edits are incorrigible, and need to be completely reworked or removed (such as introducing widespread, irrelevant rumors on the biography of a celebrity).

      So, at this time, some editors remove the text, with an explanation in the edit summary. Sometimes anonymous editors read the edit summaries, sometimes they don't. Often they wonder why their text got removed, justifiably so. Some users take that personally and begin accusing us of being "grammar Nazis", or even "suppressors of the truth" (I've heard that one before). But in a way, we're just trying to keep everything in order.

    • I edit frequently. Well, it goes in spurts depending on the topic, what I find wrong with it and how much time I have. But I haven't registered and don't plan on doing so. This doesn't mean I'm lazy, stupid, or have something to hide. I don't register because I don't want Wikki to have my personal information. This isn't because I have done something wrong, It isn't because I vandalize, and it defiantly isn't because I an hiding something. It is because it isn't any of their business.

        Um... you don't need *anything* to register a Wikipedia account. While the login form [wikipedia.org] may ask you for a ton of fields, only your username and password are required; nothing else is (aside the CAPTCHA, but that goes without saying). In fact, being an unregistered editor exposes your IP address to the public, while registered editors are covered by the Wikimedia privacy policy [wikimediafoundation.org].

    I've made only one edit ever on Wikipedia, in the section on heat pipes. I happened to notice a minor, but not insignificant, omission.

    I would imagine that most single edits are like that - someone with a good depth of knowledge on a subject, noticing something that's not quite right. The threshold for action is high enough that you'd only do it if it was worthwhile.

    I often don't log in when i want to edit an article, because i don't care how my "rep" is, i just want to fix something.

    If a contributor contributes regularly from a dynamic IP address, are these contributions all considered by different anonymous users? As far as I know, dynamic IPs are quite common and if their data was taken over different days (I didn't notice a mention of their time frame in the article, except they took the data "as of March 1st 2005") this could explain why they found anonymous users with less contributions tended to make more quality edits.
  • Generally if you just make a few anonymous edits, you're reading something, and you know it is wrong and change it. Or you change a spelling/grammar mistake. And if someone is making A LOT of anonymous edits, it's probably random gibberish.

    And if you're going to go though the trouble of making an account, you're either going to do a quick piece of vandalism and leave, or be an active contributor.

    I don't even think this is hindsight bias kicking in for calling this obvious. It really is just common sense. I'

    • I'm surprised someone actually got money to research this.

      Research is useful even if it's obvious. Previously we couldn't cite anyone if we wanted to say that anons who edit once or twice make good edits. Now, thanks to this research, we can. While it's true that these researchers could spend their time and money in better questions, for example examining P=NP, but this research is still useful, if not for everything else, at least for putting it in the references of some other wiki-related research. Now, if I want to write a paper on wikis, I can cite their

  • I find it strange that it is suggested that logged-in users care about their reputation. I am such a logged-in user [wikipedia.org] and I don't care that much about reputation or what people may think or say about me, even though my Wikipedia account is linked with my real name. I mostly care to improve articles or correct misunderstandings. If I find that in some specific occasion I can make the encyclopedia better at the cost of making 500 people hate me, I won't give a fsck what the people are going to think or say a

    anon contributors tend to be the sort that only make minor contributions, sure they fix a typo or add something useful from time to time but it is the long termers who do the real meat of the editing trying to keep structure to the articles, add citations and so on.

    I am not a registered user, but i browse wikipedia quite frequently, and when i spot a simple error, i usually modify it. I think that lots of the anonymous contributors have this same pattern, so i am not impressed with this study.
