Wikipedia:Common sense and decision making

While Wikipedia tries to make sure that every decision its admins make is backed up with policy, unfortunately there are times when decisions will be made based on an admin's perception of what appears to be the common sense thing to do even if it is not clearly backed up by a specific policy. This essay is designed to outline why this is sometimes necessary, but also to help draw a line between making necessary decisions based on common sense and abusing one's authority as an admin by making a controversial decision (e.g. issuing a block) without sufficient justification.
