I have long claimed that Wikipedia is strongly biased against knowledge that comes either from non-English-language sources and from cultures (and subcultures) where most of their practices are undocumented. This is cultural imperialism. And I have also long claimed that its now-standard requirement for references (that are not dictionaries and encyclopaedias) are also hindrances into knowledge dissemination. However, during today’s synchronous seminar a different picture of how exclusive Wikipedia has become emerged. It turns out that last year they also did a class project on Wikipedia. And it turned out that most of the stuff they wrote about were deleted. Not edited. Just deleted. On what amounts to bogus grounds. We are talking about a field that, even though can still be emerging already, already has tons of English-language literature published in English-speaking countries. This is a bias that is not even against non-white, non-English-speaking cultures. It is outright unfathomable. What of attitude, really, is this? This of course is rooted not only in the current focus of references, but also on the “principle” of “notability,” which I have always found to be incomprehensible. You can’t imagine when anything will become important. If there were no “notability” requirement, then the second the thing becomes “notable” (whatever notable means), Wikipedia will be the only encyclopaedia in the world to talk about that thing. That would be an unmatched advantage. Whoever is in control of Wikipedia certainly has no such vision. They only focus on short term measurable success, on duplicating the accomplishments of traditional encyclopaedias. They used to talk about knowledge contribution as their fundamental principle; but that is probably one of the biggest lies that ever came out of an entity that purports to belong to the free culture.
