Study finds Wikipedia to be about as accurate as Britannica
by Mike Adams, the Health Ranger, NaturalNews Editor
Wikipedia has been found to be about as accurate on science as the Encyclopedia Britannica, according to a study by the British journal Nature. However, reviewers found many factual errors, omissions or misleading statements in both.
The British journal Nature examined a range of scientific entries on both works of reference and found few differences in accuracy.
Wikipedia is produced by volunteers, who add entries and edit any page.
But it has been criticised for the correctness of entries, most recently over the biography of prominent US journalist John Seigenthaler.
Wikipedia was founded in 2001 and has since grown to more than 1.8 million articles in 200 languages.
It is based on wikis, open-source software which lets anyone fiddle with a webpage, anyone reading a subject entry can disagree, edit, add, delete, or replace the entry.
We're very pleased with the results and we're hoping it will focus people's attention on the overall level of our work, which is pretty good Jimmy Wales, Wikipedia founder It relies on 13,000 volunteer contributors, many of whom are experts in a particular field, to edit previously submitted articles.
In order to test its reliability, Nature conducted a peer review of scientific entries on Wikipedia and the well-established Encyclopedia Britannica.
The reviewers were asked to check for errors, but were not told about the source of the information.
The Encyclopedia Britannica declined to comment directly on the findings; but a spokesman highlighted the quality of the entries on the free resource.
"But it is not the case that errors creep in on an occasional basis or that a couple of articles are poorly written," Tom Panelas, director of corporate communications is quoted as saying in Nature.
Wikipedia came under fire earlier this month from prominent US journalist John Seigenthaler.
The founding editorial director of USA Today attacked a Wikipedia entry that incorrectly named him as a suspect in the assassinations of president John F Kennedy and his brother, Robert.
Wikipedia has responded to the criticisms by tightening up procedures.
