"The four conditions of Daubert are well known: general acceptability by the relevant scientific community, knowledge of the actual or potential rate of error for the practice, subjection of the practice to peer review, and actual or potential testability of the method's results. This final condition is an overt homage to Karl Popper's falsification model, which is referenced heavily in the Daubert court's decision. The Daubert decision is only one case law interpretation of Federal Rule 702 and not all philosophers of science agree that the Popperian approach is what defines science most accurately and, in fact, few adhere to this model today." from "The Cheapening of Forensic Science: How Philosophical, practical, and legal definitions of science shape our discipline", Max M.
