In one of the items in the weekly email I received just today, you said, in response to a reader who quoted a Wikipedia article, “Anybody can add anything to a Wikipedia article. At 2.6 million English-language articles, Wikipedia is assuredly the most impressive piece of participatory scholarship yet produced. The fact remains that, from the standpoint of authoritativeness, a Wikipedia article merely represents the opinion of whoever got to it last.”
Well, not quite. What it represents is the degree to which the editor who added the information follows Wikipedia policy on Verifiability, Citing Reliable Sources, and Neutrality. If you come across a poorly written, uncategorized stub article filled with unsourced POV material, then yeah, you shouldn’t rely on that material. But at the other end of the spectrum, if you’re using a Featured Article–that is, an article that has been Peer Reviewed, and judged to be well written, and comprehensive in its handling of the subject, then yes, you can rely on it, as it does not represent anyone’s “opinion”, any more than any other source you might prefer to use. For my part, as a Wikipedia editor since March 2005, and an administrator since November 2007, I can assure you that I always follow WP policy, and none of my editors are derived from my “opinion”. They’re derived from the sources I cite for the material I add. Thus, if the article mentioned by that previous reader of yours cited a book by a historian who is an expert on that school, a New York Times article written by an alumnus on that school, or that school’s own website, then you can follow those sources to verify the accuracy of the information. To dismiss any given article, regardless of its quality as merely representing someone’s “opinion”, without first reviewing it, is not only simplistic, it implies that other sources that have a greater brand name cache, are not themselves derived from the biases of their authors, which is silly.
Keep up the great work, and Happy Holidays!
