"The task of empirical social science thus defined is demanding. The first challenge is getting the right facts: We always must decide whether something we know about social life is central and representative or is merely peripheral and unusual. We must also separate what the observer wants to believe (bias) from the real facts. A second challenge is to set forth knowledge of the facts sparingly; we must reduce the information we receive about empirical reality to a comprehensible and testable set of propositions."[David M. Trubek, "Where the Action Is: Critical Legal Studies and Empiricism," 36 Stan. L. Rev. 575, 580 (1984)]
