The BBC reports that a recent study on the accuracy of Wikipedia, the online encyclopedia, by the prestigious journal Nature is “fatally flawed.” Nature’s report was published last December and compared the accuracy of Wikipedia and the Encyclopaedia Britannica. The study found that both were about as accurate as each other in terms of science entries. Encyclopaedia Britannica has fought back against Nature’s study, and called for the paper to be retracted. The study only found eight serious errors, four from each encyclopedia. However, the Nature study did find factual errors in other subjects, 162 in Wikipedia compared to 122 in Encyclopaedia Britannica. Encyclopaedia Britannica does not claim to be error free, but it does say that the research exaggerated its inaccuracies and that “Britannica was far more accurate than Wikipedia.”
