Where we often see big controversies, though, is with editors who are unintentionally and often unknowingly disruptive while trying to help. This is where we sometimes see an unintended side effect of our (generally quite useful) notion of assuming good faith. Many editors have focused so much on this tenet that they have come to believe that good faith is all that is required to be a useful contributor. Sadly, this is not the case at all. Competence is required as well. A mess created in a sincere effort to help is still a mess.

Clearly, every editor is incompetent when doing some types of edits in certain subject areas, so it is important to know or discover your limitations.

Assuming that people are trying to help seems trivial—but if someone is unable to help or is sometimes helpful but at other times disruptive, their edits may cause a net loss to the project. The proverbial might have good intentions, but he's clearly bad for business. We always must value the project as a whole more than we value the contributions of any individual editor.

So, the next time someone posts on a noticeboard saying "Editor Example is causing problems—here are the diffs to demonstrate this", or "Disruptive editor Example is asking for an unblock", think twice before just "Assuming good faith". The person making the complaint is probably already assuming good faith, and they're concerned about a lack of competence, not a lack of good faith. Both competence and good faith are required to edit usefully. If an editor has already demonstrated incompetence that causes disruption, no amount of good faith can fix the problem resulting from the editor's lack of competence.

... is often criticized for being uncivil. The most sensible defense to such criticism is that the primary purpose of this essay is not to present it to competence-lacking editors to let them know they are incompetent. After all, as argued here, they are either incapable of recognizing their own incompetence (see Dunning–Kruger effect) or are incapable of changing their behavior. Rather, the purpose of this essay is to inform discussion amongst other editors of how to deal with issues arising from incompetence. So, if WP:COMPETENCE seems to apply to an editor, it is usually not appropriate to tell them so.
