The study concluded that "Wikipedia comes close to Britannica in terms of the accuracy of its science entries", [4] although Wikipedia's articles were often "poorly structured". Among Britannica's criticisms were that excerpts rather than the full texts of some of their articles were used, that some of the extracts were compilations that included articles written for the youth version, that Nature did not check the factual assertions of its reviewers, and that many points the reviewers labeled as errors were differences of editorial opinion.

One article had "a marked deterioration towards the end" while another had "clearer and more elegant" writing, a third was assessed as less well written but better detailed than its competitors, and a fourth was "of more benefit to the serious student than its Encarta or Britannica equivalents".

No serious errors were noted in Wikipedia articles, whereas serious errors were noted in one Encarta and one Britannica article.
