Wikipedia vs Britannica: Not that much difference

Given how long Brittanica has been around, and given that anybody can edit Wikipedia, you're expect there to be a bigger difference in their respective accuracies. In a recent blind side-by-side review of 42 science articles, the difference in accuracy was not particularly great: the average science entry in Wikipedia contained around four inaccuracies; Britannica, about three. In fact, Wikipedia had more articles than Britannica that were completely defect free. On a per word basis, Wikipedia outperforms Britannica by 3/5. The detailed comparison can be found in table on this page.
