Wikipedia:Revert only when necessary

Reverting is reversing a prior edit, in whole or in part. Revert vandalism upon sight but revert an edit made in good faith only after careful consideration. It is usually preferable to make an edit that retains at least some elements of a prior edit than to revert the prior edit. Furthermore, your bias should be toward keeping the entire edit.

In the case of a good faith edit, a reversion is appropriate when the reverter believes that the edit makes the article clearly worse and there is no element of the edit that is an improvement. This is often true of small edits. Edits that introduce bias or undue weight should be reverted until consensus is built.

Whenever you believe that the author of an edit was simply misinformed, made a mistake, or did not think an edit through, go ahead and revert. If that editor (or anyone else) re-reverts, you will know it is more than that, and you should be more conservative in deciding whether to revert it again.

There are a number of things that sometimes motivate an editor to revert, but should not.

The first and foremost alternative to reverting when you find you disagree with an edit is to find a third version of the text that incorporates at least some of the elements of the prior text and the current text. Sometimes that's as easy as making the article state that there is controversy about something.

You could also discuss an edit directly with the editor who made it, on that editor's talk page, and request that the editor modify his own work. Or convince you that it's best as it stands.

High-frequency reversion wars make the page history less useful, make it hard for other people to contribute, and flood recent changes and watchlists. forbids anyone from reverting any single article more than three times within a period of 24 hours, with certain exceptions. This is a strict limit, not a given right; you should not revert any one article more than three times daily. Violation of this rule may lead to protection of the page on the version preferred by the non-violating party; blocking; or investigation by the Arbitration Committee. Usage of sock puppets attempting to circumvent this rule does not prevent a violation. See for details on this.
