On the permissiveness of the abductive theory of method.

In this article, the author examines Romeijn's (2008) contention that the account of theory construction in the abductive theory of scientific method suffers from the problem of the underdetermination of theories by empirical evidence. Following Romeijn, the author focuses on the issue of underdetermination as it affects the method of exploratory factor analysis, the strategy of analogical modeling, and the theory of explanatory coherence. The author argues that in each case there are sufficient methodological resources available to researchers to use these methods to good effect. Additionally, he comments on the normative force of the abductive theory of method.
