> Even if you are sure something is true, it must have been previously published in a reliable source before you can add it. If reliable sources disagree with each other, then maintain a neutral point of view and present what the various sources say, giving each side its due weight.

Wikipedia cares that its contents are taken from reliable sources, which can be independently verified. Not all news media are reliable sources, and in fact academic papers and journals and published books are generally more reliable than news media.
