Political science is an intensely quantitative discipline, and models are central. Political scientists use models--formal and informal, statistical and qualitative--to investigate and illuminate causal mechanisms, generate comparative data, and understand the conditions under which certain outcomes are expected to occur. But even though the use of models has grown dramatically in the discipline, there is very little understanding among political scientists of the role or function that models play in the scientific enterprise more generally. Moreover, theoretical models and empirical models have traditionally been treated as separate (hence the division between theorists and empiricists). Today, however, the emphasis is on using models to generate testable predictions that serve as hypotheses for subsequent data analysis. But how do we justify and rationalize the method? Why test predictions from a deductive, and thus truth-preserving, system? David Primo and Kevin Clarke tackle these central questions in this novel work of methodology. They argue that the lack of a suitable justification for model testing is not the only reason to revisit the role of models in political science. Most importantly, they contend that models should be seen as 'objects' and thus neither true nor false. Rather, they should be evaluated in the same fashion as models are evaluated in the physical sciences--good models are useful for particular purposes. Nothing more, nothing less. Divided into two parts, the book first establishes that no social scientific endeavor is philosophy-free. The second part focuses on different types of models, and closes with a framework for integrating theoretical and statistical models.

Reviews
This is an outstanding book that should be read, thought about, and discussed by every political scientist. Professors Clarke and Primo provide a clear discussion of what models are, a persuasive critique of current practice in the discipline, and solid guidance for how to effectively assess models of all types. This is a must-read. * Andrew D. Martin, Professor of Law and Political Science, Washington University in St. Louis *
This is not a book for those who need the comforts of conventional wisdom. It mounts a powerful challenge to our prevailing orthodoxies, both theoretical and methodological. This is fresh, aggressive thinkin? * a joy to encounter.Christopher Achen, Princeton University *
This smart book proposes two things simultaneously for political scientists. First, we ought to have a consensus on what we should not do with our models, and that is we should not insist on testing them as models. But second, we also ought to allow for diversity in what our theoretical models can do, how they are judged, and how they are structured. They argue that models ought to be judged based on how useful they are. The same can be said for books-and this is a very useful book. * Ken Kollman, University of Michigan, Ann Arbor *
