How Reliable is Wikipedia?

Well, pretty damn reliable apparently. Or at least that is the view expressed by the scientific journal Nature who have just carried out the first peer based comparative review of Wikipedia and Encyclopaedia Britannica in terms of their science coverage. Clearly cases like the Seigenthaler one are the exception rather than the rule, and Britannica itself is not without its problems since of the eight “serious errors” reviewers found – including misinterpretations of important concepts – four came from each source, the journal reported. Maybe people should be thanking John Seigenthaler for raising Wikipedia’s profile. Well done Wikipedia.

One of the extraordinary stories of the Internet age is that of Wikipedia, a free online encyclopaedia that anyone can edit. This radical and rapidly growing publication, which includes close to 4 million entries, is now a much-used resource. But it is also controversial: if anyone can edit entries, how do users know if Wikipedia is as accurate as established sources such as Encyclopaedia Britannica?

…..an expert-led investigation carried out by Nature — the first to use peer review to compare Wikipedia and Britannica’s coverage of science — suggests that such high-profile examples are the exception rather than the rule.

The exercise revealed numerous errors in both encyclopaedias, but among 42 entries tested, the difference in accuracy was not particularly great: the average science entry in Wikipedia contained around four inaccuracies; Britannica, about three.

About Edward Hugh

Edward 'the bonobo is a Catalan economist of British extraction. After being born, brought-up and educated in the United Kingdom, Edward subsequently settled in Barcelona where he has now lived for over 15 years. As a consequence Edward considers himself to be "Catalan by adoption". He has also to some extent been "adopted by Catalonia", since throughout the current economic crisis he has been a constant voice on TV, radio and in the press arguing in favor of the need for some kind of internal devaluation if Spain wants to stay inside the Euro. By inclination he is a macro economist, but his obsession with trying to understand the economic impact of demographic changes has often taken him far from home, off and away from the more tranquil and placid pastures of the dismal science, into the bracken and thicket of demography, anthropology, biology, sociology and systems theory. All of which has lead him to ask himself whether Thomas Wolfe was not in fact right when he asserted that the fact of the matter is "you can never go home again".
