I have noticed that there are many people, both in and outside of DU, who exhibit a sort of condescending attitude towards the use of Wikipedia as an information source. One DUer for example, during the course of my argument with him, responded to my use of a Wikipedia reference with a comment along the lines of “Wikipedia! ha ha”.
To the contrary, I have found Wikipedia to often be a useful source of information. In some respects it has important advantages over most other sources of information. That is not to say that its information is always correct or that there are not usually other sources of more informative information on a given topic. But the idea of discounting or mocking information simply because it came from Wikipedia is ridiculous.
In this post I will try to counteract what I see as some of the prejudices against Wikipedia as a source of information, by first describing how and why I use it, and then discussing some of its advantages over most other sources of information. Lastly, I will describe what I see as its most important limitation.
My use of Wikipedia when posting DU articlesStatements made in Wikipedia articles can be classified into three categories with respect to references: 1) those backed up with on-line references; 2) those backed up with references that are not available on-line – such as from a book; and 3) those backed up by no references (in which case it will usually be accompanied by the notation “needs reference”).
I generally use links to reference my factual statements in my DU articles (OPs), and sometimes my links are to Wikipedia articles. I do that when I believe that the Wikipedia article is the best reference I have found. But I rarely if ever link to a Wikipedia article if the information that I am referencing from Wikipedia is backed up by an on-line source, because in that case it is almost always preferable to link to the original on-line source. However, if the Wikipedia information that I wish to reference is backed up by a source that is not on-line or by no reference at all, then I will link to the Wikipedia article.
Other than using Wikipedia as a direct reference source, I sometimes find it useful as a starting point to lead to other information. Since there are so many different editors that typically contribute to a single Wikipedia article, their articles often give a very good broad overview of current thinking on the subject, along with numerous references.
Advantages that Wikipedia articles generally have over most other information sourcesKeep in mind when I speak of these “advantages”, that doesn’t imply that better sources may not exist. My use of the word “advantage” is general, is relative to most other sources of information, and may not apply at all for some articles:
VerifiabilityOne of the major principles that Wikipedia uses is “
verifiability”. Wikipedia policy states that “Editors should provide a
reliable source for quotations and for any material that is challenged or likely to be challenged, or the material may be removed”.
That of course begs the question, what is a “
reliable source”? Here is some of what Wikipedia says about “reliable sources”:
Articles should be based upon reliable published sources with a reputation for fact-checking and accuracy. Reliable sources are necessary both to substantiate material within articles and to give credit to authors and publishers in order to avoid plagiarism and copyright violations. Sources should directly support the information as it is presented in an article and should be appropriate to the claims made: exceptional claims require high-quality sources. In general, the most reliable sources are
peer-reviewed journals and books published in university presses; university-level textbooks; magazines, journals, and books published by respected publishing houses; and mainstream newspapers.
Some DUers will object that so-called mainstream newspapers, for example, are not reliable sources. That is often a valid point – a point that I myself have often made. However, almost everyone who writes articles, including us on DU, quotes from mainstream newspapers when we believe it is useful to our article to do so. At least the reader knows where the quote came from and can check it out further if he or she wishes to do so.
Why do I say that this verification process represents an advantage over most (though certainly not
all) other information sources? It is simply that most articles that I read on the Internet or newspapers or magazines (or watch on TV) back up less of their factual statements with references than what I generally find on Wikipedia. If anyone disagrees with that statement I would like to hear it.
Neutral point of viewA so-called “
neutral point of view” is of course very difficult to define. Here are some of the relevant points that Wikipedia makes about it:
All Wikipedia articles must be written from a neutral point of view… The neutral point of view is a means of dealing with conflicting verifiable perspectives on a topic as evidenced by reliable sources. The policy requires that where multiple or conflicting perspectives exist within a topic each should be presented fairly. None of the views should be given undue weight or asserted as being judged as "the truth", in order that the various significant published viewpoints are made accessible to the reader, not just the most popular one…. The neutral point of view is neither sympathetic nor in opposition to its subject: it neither endorses nor discourages viewpoints…. Article content should clearly describe, represent, and characterize disputes within topics, but without endorsement of any particular point of view…. Articles should provide background on who believes what and why… Neutrality requires views to be represented without bias. All editors and all sources have biases (in other words, all editors and all sources have a point of view) – what matters is how we combine them to create a neutral article. Unbiased writing is the fair, analytical description of all relevant sides of a debate, including the mutual perspectives and the published evidence.
If this description of “neutral point of view” is not perfectly clear, that is because this is a very complex subject. I believe that the key words and phrases in this description are “fairly”, “undue weight”, and “bias”. But these too are words and phrases that can be very difficult to agree on.
For example, since I am a liberal it is possible or even likely that most people would consider my writing to be biased in a liberal direction. Yet, I try to write from a neutral point of view by clearly differentiating the facts that I present from my opinions, and by documenting what I consider to be facts. Part of my liberal thinking includes my belief that most U.S. military interventions are unjustified and that poor people generally deserve better in life than what they have. I sometimes state those beliefs as opinions, but I also often try to
back up those opinions with documented facts. Does that mean that my writing is not “fair”, gives “undue weight” to the value of avoiding war, or is biased towards poor people? I don’t think that it does, but I’m sure that many would disagree.
Anyhow, the good thing about Wikipedia’s policy of “neutral point of view” is that it gives us a good idea of the prevalent points of view on an issue, and it also means that the Wikipedia editors are forced to be very careful about sticking to the facts and omitting their own opinions from their writing. When I’m researching a topic I generally just want to know the facts and don’t care much about the personal opinions of the sources.
The “work in progress” principle and consensusPart of the source of the condescension that some people show for Wikipedia is based on the fact that there are so many editors involved in many or most of their articles. This can create somewhat of a chaotic process, and usually results in articles being changed from time to time. Some people see this as a process that results in serious flaws in Wikipedia articles. But I look at it as an advantage rather than as a flaw.
The “work in progress” principleHow can we have confidence in an article that could say something very different tomorrow and might have said something very different yesterday? Well, consider it a self-corrective process. Most articles never change their content. That means that if there are flaws in them, those flaws stay there. But Wikipedia has a process for correcting flaws. Here is what Wikipedia says about that:
One of the great advantages of wikis is that incomplete or poorly written first drafts of articles can, over time, evolve into masterpieces through collaborative editing. Wikipedia is a reference work, but it is also perpetually a
work in progress.
Why is it a
good thing for something to be a “work in progress”? It is simply that most articles are finished when they are written and therefore have no chance for improvement. Many articles are excellent to begin with and therefore are not in need of much improvement. That applies to some Wikipedia articles as well as to some other articles. But at least with Wikipedia articles there is a built in process for removing flaws over time.
ConsensusAdditionally, the facts that Wikipedia articles are worked on by numerous editors and that they use the consensus process provide additional safeguards for ensuring that articles are accurate. Here is part of what they say about the “
consensus” process:
Consensus is part of a range of policies on how editors work with others, and part of the Fourth pillar of Wikipedia code of conduct. Editors typically reach a consensus as a natural and inherent product of wiki-editing… Consensus discussions should always be attempts to convince others, using reasons… Consensus is not simple agreement… Consensus is a broader process where specific points of article content are considered… in the hope that editors will negotiate a reasonable balance between competing views.
Consensus is a process. It is not simply a matter of taking the average view and using that as the “truth”. For example, consider 100 editors trying to work out a consensus on how many Iraqis have been killed as a result of the U.S. invasion and occupation of Iraq. Suppose that the initial average estimate of the ten people is 50,000, with one person believing the true number to be 1.2 million. Obtaining consensus involves discussion and argument. If that one editor has more convincing information than the 99 others, the eventual consensus could end up at 1.2 million, rather than with the initial average. That is why the consensus process often results in better information than what people could arrive at individually, even when a very “reputable” editor makes all the decisions.
The actual
Wikipedia article on the subject of Iraqi war deaths presents several different estimates. Included in those estimates are the statement, “In December 2005 President Bush said there were 30,000 Iraqi dead”, as well as the results and methods of several studies, some which demonstrated totals of
over a million deaths. The reader can read in Wikipedia how the various estimates were obtained or look up the original sources and develop his or her own opinions.
My opinion of the biggest limitation of the Wikipedia processPerhaps the most important limitation of the Wikipedia process is a result of its insistence on sticking to so-called “reliable” sources. Of course it’s good to have a process in place for ensuring accurate information. But how does one determine if a source is “reliable? Wikipedia does have guidelines for that, but are those guidelines sufficient? For example, is there sufficient awareness of the bias inherent in our corporate owned news media? I don’t believe there is, though I can’t prove that. Wikipedia says that self-published books may be acceptable as references if written by “established experts”. But what about the corporate bias in determining who are “established experts”?
If you really want to determine the validity of a source, there are in many cases more important considerations than the so-called reputation of the source. As an epidemiologist, I have often participated in the review process of submitted manuscripts, and I can say without hesitation that one can often find better articles in obscure medical journals than in the most “reputable” ones. There are many considerations that go into determining the validity of a scientific (or any other) article, it takes a lot of time to consider all the relevant issues, and perhaps the Wikipedia editors don’t usually do that.
Consider the issue of the 9/11 attacks as an example. To their credit, the Wikipedia editors do mention that there are conspiracy theories that challenge the accepted version of events. But in my opinion that part of the
Wikipedia article on the subject gives the alternative versions very short shrift (but let’s not discuss that here, since I don’t want to see this post go to the dungeon). Perhaps that’s because of too much emphasis on maintaining a “neutral point of view” or accepting only “reliable” sources.
SummaryIn summary, I often find Wikipedia to be a very valuable resource, and I believe that the condescending attitude that some people show towards it is misplaced. It is meticulous about documenting its sources, it sticks to the facts and strives to clearly label opinions as opinions, and it has processes in place to achieve objectivity and avoid bias.
I look at the fact that numerous editors are used for individual articles as a strength rather than as a weakness. So-called “reputable” sources of information use much fewer editors, who are often highly paid and “professional”. But consider who pays them and what biases might be involved in that fact. I would take numerous unpaid, non-professional editors any day over a single professional editor who is paid by a corporation whose financial interests may interfere with its ability (or motivation) to evaluate and present information in an unbiased manner.
The validity of Wikipedia articles is limited by some of the same factors that interfere with the validity of any articles, including the difficulties of determining what constitute “reliable” sources of information. Most important, there may be too much emphasis on relying on corporate or government propaganda in making those determinations.
