Verifiability
Wikipedia does not have to be truthful, but it is important that the information must be confirmed by reliable sources.[1]. The phrase "the threshold for inclusion is verifiability, not truth" meant that verifiability is a necessary condition (a minimum requirement) for the inclusion of material, though it is not a sufficient condition (it may not be enough). Sources must also be appropriate, and must be used carefully, and must be balanced relative to other sources.
