title: Commentary on Meehl and Waller's (2002) path analysis and verisimilitude.
abstract: P. E. Meehl and N. G. Waller's (2002) proposed method may not yield unique solutions for model parameters nor unique solutions for model lack of fit. The author argues from a naturalistic-cognitive philosophy of science that science seeks objective knowledge and that hypothesis testing is central to achieving that goal. It is also argued that P. E. Meehl and N. G. Waller's proposal blurs the distinction between hypothesis testing and explorations of the data seeking an optimal model to serve as a prospective inductive generalization. But it is noted that inductive generalizations are never unique and must be tested to eliminate those that reflect subjective aspects of the researcher's methods and points of view.
