AND FALSIFIABILITY:
THE FIRST DA UBERT FACTOR
AND THE PHILOSOPHY OF SCIENCE*
D.H. Kaye**
ABSTRACT: In Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579, 593
(1993), the Supreme Court suggested that in evaluating the admissibility of scientific
evidence, federal courts should consider whether a theory or technique ... can be (and
has been) tested. Several commentators have thought that this suggestion represents an
adoption of the philosophy of science of Karl Popper, and several courts have treated the
abstract possibility of falsification as sufficient to satisfy this aspect of the screening of
scientific evidence called for in Daubert. This essay challenges these views. It first
explains the distinct meanings of falsification and falsifiability. It then argues that
while the Court did not embrace the views of any specific philosopher of science, inquiring
into the existence of meaningful attempts at falsification is an appropriate and crucial
consideration in admissibility determinations. Consequently, it concludes that courts that
are substituting mere falsifiability for actual empirical testing are misconstruing and
misapplying Daubert.
