I've just about given up with trying to get Gabriel to stick to any subject, so this post will be about one of his favorite distractions. Wikipedia is to Gabriel as shiny objects are to ferrets.
Since I won't shy away from melting Gabriel's brain by saying what I actually think about Wikipedia (though his functional illiteracy will prevent him from comprehending what I say), I'll say it quite simply: Standard research principles still apply.
Wikipedia deserves no special consideration, despite Gabe's protests to the contrary. Wikipedia articles should be approached in the same manner you would approach any piece of information. It's that simple. Wiki pages aren't magically correct or incorrect on their own. They're only as good as the sources they cite, the logic they employ, and so forth. The internet may get more people together from wider areas and speed up their exchange of ideas, but doing something faster doesn't and shouldn't change the underlying process. It doesn't matter if you're talking about a prestigious library or bathroom graffiti. Science remains science. The principles you learned in your writing classes are still relevant, despite the essentially trivial addition of how to cite websites to your style books.
Gabriel, it seems, believes otherwise: Wikipedia is Automatically Wrong, no matter how much good evidence an article cites. If someone were to conduct a scientific study on the sky on a clear, sunny day, taking snapshots with accurate digital cameras and objectively measuring the hue from the resulting image files, all that scientific rigor is for naught if someone posts an article about the study on Wikipedia: If Wikipedia cites that study and summarizes the results by saying the sky is blue, it magically transforms all those collected image data so that the sky is chartreuse or magenta. In short, Gabe is telling us to screw epistemology, Wikipedia has ushered in a newage (rhymes with sewage) of contra-revelation: Instead of having allegedly infallible fairy tale books to inform us of the world (revelation), he believes we now have the Automatically Wrong Wikipedia to tell us how the world isn't.
I say otherwise: Wikipedia is just another reference source. Like all reference sources, it has its own biases, its own flaws, and so forth. It's only unique in that it's continuously updated, sometimes for the better, sometimes for the worst. The presence or absence of Wikipedia has no impact on the core of epistemology. It does not overturn logic. It does not invalidate the scientific method. It does not magically transmute the data scientists so rigorously collect.
I simply fail to see why Gabriel is so pathologically obsessed with something that changes so little about the world.
