We say that a statement is underdetermined by available facts when it and an alternative and different statement or theory are equally consistent with that body of facts. It may be that two physical theories have precisely the same empirical consequences -- perhaps wave theory and particle theory represent an example of this possibility. And …
The inexact science of economics
Image: social accounting matrix, Bolivia, 1997Economics is an "inexact" science; or so Daniel Hausman argues in The Inexact and Separate Science of Economics (Google Books link). As it implies, this description conveys that economic laws have only a loose fit with observed economic behavior. Here are the loosely related interpretations that Hausman offers for this …
Piecemeal empirical assessment of social theories
The philosophy of science devotes a large fraction of its wattage to this question: what is the logic of empirical confirmation for scientific beliefs? (A good short introduction is Samir Okasha, Philosophy of Science: A Very Short Introduction.) In the natural sciences this question became entangled with the parochial fact about the natural sciences, that …

And it implies some sort of theory of scientific rationality -- a theory …

On the methodological side there was the idea that the logic of explanation and confirmation should …

Empirical constraints on sociological theories
What makes sociology "scientific"? An important component of a reply is that assertions, hypotheses, and theories are subject to the test of empirical evidence. Hypotheses need to be evaluated in terms of observations of how the real world behaves. We should evaluate our assertions in terms of their fit with the empirical facts. This is …
