Usage Note: Since the word fact means "a real occurrence, something demonstrated to exist or known to have existed," the phrases true facts and real facts, as in The true facts of the case may never be known, would seem to be redundant. But fact has a long history of use in the sense of "an allegation of fact" or "something that is believed to be true," as in this remark by union leader Albert Shanker: "This tract was distributed to thousands of American teachers, but the facts and the reasoning are wrong." This usage has led to the notion of "incorrect facts," which causes qualms among critics who insist that facts must be true. The usages, however, are often helpful in making distinctions or adding emphasis.
