"Wikipedia relies on “consensus” as the final arbiter of content, rather than a ruling board of supposedly expert editors, as in, say, the Columbia Encyclopedia. Wikipedia’s continual give-and-take corrections work well for math and science, less well for history and literature where consensus is sometimes ill-informed. Dubious romantic or heroic stories about larger-than-life figures like W.B. Yeats or Ernest Hemingway cannot be dislodged because consensus favors familiar myths."
