## Background

Wikipedia is a free, collaborative, online encyclopedia which allows its users to write and edit articles via wiki software. The website provides a user-friendly interface for both editing on articles and reversing other users' edits.$^{:189}$ Conflicts over content within articles often arise among editors, which may result in edit wars.$^{:62}$ An edit war is a persistent exchange of edits representing conflicting views on a contested article,$^{:62}$ or as defined by the website's policy: "when editors who disagree about the content of a page repeatedly override each other's edits." Edit wars are prohibited on Wikipedia$^{:146}$ and editors are encouraged to seek consensus through discussion, however administrative intervention may be applied if discussion is unfruitful in resolving the conflict. Generally, edit wars are provoked by the presence of highly controversial content, such as abortion or the Israeli–Palestinian conflict, but can also occur due to other disputed matters, such as the nationality of artist Francis Bacon.
