The (in)accuracy of long-tail Wikipedia articles – can you help improve mine?
The quality of Wikipedia has been well established. A well-known study was carried out in 2005 by scientific journal Nature showing that the accuracy of Wikipedia articles on science was comparable to that of Encyclopedia Brittanica. A more recent study by Epic and University of Oxford again showed comparable quality of articles across many domains of study and languages.

However the problem is that both of these studies compared articles of substance on academic topics.
