Technology Review: Wikipedia and the Meaning of Truth

Many people, especially academic experts, have argued that Wikipedia's articles can't be trusted, because they are written and edited by volunteers who have never been vetted. Nevertheless, studies have found that the articles are remarkably accurate. The reason is that Wikipedia's community of more than seven million registered users has organically evolved a set of policies and procedures for removing untruths. This also explains Wikipedia's explosive growth: if the stuff in Wikipedia didn't seem "true enough" to most readers, they wouldn't keep coming back to the website.

These policies have become the social contract for Wikipedia's army of apparently insomniac volunteers. Thanks to them, incorrect information generally disappears quite quickly.

So how do the Wikipedians decide what's true and what's not? On what is their epistemology based?

Unlike the laws of mathematics or science, wikitruth isn't based on principles such as consistency or observa­bility. 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. --Simon L. Garfinkle, Technology Review
