Ignore all rules

"Ignore all rules" (IAR) is a policy of the English Wikipedia, an online encyclopedia, which reads (emphasis and links in original): "If a rule prevents you from improving or maintaining Wikipedia, ignore it." The rule, under different language, was proposed by Wikipedia co-founder Larry Sanger to encourage editors to add information without focusing excessively on formatting, though Sanger later criticized the rule's effects on the community.

The policy allows Wikipedia users to use a policy to occasionally work around the site's rules without rejecting the entire rule system. A study in 2012 found that in "Articles for deletion" discussions, which determine whether a Wikipedia article should be deleted, comments were given more weight when they used IAR as justification.
