Wikipedia vs. Britannica
In a study by Nature, a science journal, expert reviewers found Wikipedia science entries to be not much less accurate than Encyclopaedia Britannica entries:
[A]n 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.
Here’s how the study was done:
In the study, entries were chosen from the websites of Wikipedia and Encyclopaedia Britannica on a broad range of scientific disciplines and sent to a relevant expert for peer review. Each reviewer examined the entry on a single subject from the two encyclopaedias; they were not told which article came from which encyclopaedia. A total of 42 usable reviews were returned out of 50 sent out, and were then examined by Nature’s news team.
Only eight serious errors, such as misinterpretations of important concepts, were detected in the pairs of articles reviewed, four from each encyclopaedia. But reviewers also found many factual errors, omissions or misleading statements: 162 and 123 in Wikipedia and Britannica, respectively.
One could view the results as reflecting well on Wikipedia. One could also view them as as reflecting very badly on Britannica.
