As mentioned in several other reviews, all information on Wikipedia is user-created, internally reviewed, and moderator approved. As with a TON of internet information being passed off as "news" and "fact", there is no standard for these labels any more. Nowhere is there an authoritative source with which this information can be compared and proven. Yes, users generally cite sources, sometimes they're even required to have sources; however, those sources are often incestuous - circular references that feed off each other, rather than having any foundation outside of the echo chamber.
