How wikipedia defines truth
This means that the content of these articles really matters. Wikipedia's standards of inclusion--what's in and what's not--affect the work of journalists, who routinely read Wikipedia articles and then repeat the wikiclaims as "background" without bothering to cite them. These standards affect students, whose research on many topics starts (and often ends) with Wikipedia. And since I used Wikipedia to research large parts of this article, these standards are affecting you, dear reader, at this very moment. . . .
Unlike the laws of mathematics or science, wikitruth isn't based on principles such as consistency or observa bility. It's not even based on common sense or firsthand experience. Wikipedia has evolved a radically different set of epistemological standards--standards that aren't especially surprising given that the site is rooted in a Web-based community, but that should concern those of us who are interested in traditional notions of truth and accuracy. On Wikipedia, objective truth isn't all that important, actually. What makes a fact or statement fit for inclusion is that it appeared in some other publication--ideally, one that is in English and is available free online. "The threshold for inclusion in Wikipedia is verifiability, not truth," states Wikipedia's official policy on the subject. . . .
Just so long as someone someplace makes a claim about something it counts as being valid.
