Wikipedia edit wars: The most controversial topics by James Fransham, Lloyd Parker, Robert Jones and Phil Kenny
Everything that happens on Wikipedia is recorded, and as such, constitutes data - a signal that can be parsed for meaning. Looking at the number of times a given article is edited, only for the change to be replaced entirely by the prior text (called a "revert"), is an indicator of how controversial a topic is. Ranking the top reverts by language sheds interesting insights into different cultures. We adapted data compiled by researchers at the Oxford Internet Institute to show differences in what the world argues about.
