The Independent has a sort-of interesting article about PR firms altering Wikipedia entries. Does that surprise anyone?
Almost all of what we “know” in daily life is a consensus agreement between gatekeepers of one sort or another. I don’t necessarily have a problem with that. Much as I’d like to, I am not able to empirically verify all of the information I depend upon; I don’t have the math chops for physics or the memory for biology, so I rely on trusted sources to tell me the truth. If I doubt the information they’re giving me, I can dig in and research/test that information. Same with Wikipedia. Trust, but verify and don’t believe everything you think and be open to the possibility that your sources are wrong.
