Defining scientific progress in terms of the cumulation of knowledge, predictive power, and an “approach-to-consensus” regarding the best explanation when intellectual disputes arise, Fred Chernoff raises the critically important questions of why is there relatively little progress in the field of security studies as compared to the natural sciences, and why is there more progress in some areas of security studies than in others. He argues that one important answer to these questions is that scholars in security studies, unlike those in the natural sciences, use different philosophy of science criteria of evaluation and are rarely explicit about what those criteria are. Chernoff finds support for his argument in an empirical examination of how security studies scholars make judgments about the quality of competing explanations regarding three important research questions in the field—nuclear proliferation, balance of power and alliance formation, and the democratic peace. With respect to the latter, he argues that scholars have explicitly stated their criteria, reached agreement about the appropriate criteria, and moved towards consensus on the validity of a liberal explanation (though which particular liberal explanation is still contested). Chernoff includes a discussion of alternative explanations for the lack of scientific progress in security studies, including the fact that some scholars are answering different questions rather than providing different answers to the same question. He concludes with some useful reflections on the role of metatheory in international relations research programs.
I was surprised to be asked to write a review article of “Still notable: Reassessing theoretical ‘exceptions’ in Canadian foreign policy literature” by David R. Black and Heather A. Smith. This article that introduces the 2014 annual John W. Holmes issue of the leading Canadian journal International Journal is itself a review article on the field of Canadian foreign policy. It is conceived as an update of a similar article written by the two authors in 1993 and published by the Canadian Journal of Political Science. I was asked to write a review of a review article inspired by a review article. And yet, not only did I enjoy very much reading the piece – which is not surprising as it is written by two seasoned and prominent scholars in Canadian foreign policy – but writing that review proved itself to be a fascinating and exciting opportunity to discuss important issues facing the field.
The relations between the disciplines of history and political science have always been both close and, partly for that reason, contested. Political science grew in part out of history, which led its practitioners to be both deeply imbued with historical knowledge and to need to differentiate themselves from the study of history. Until about fifty years ago, the overlap between the disciplines was especially great in the international area, and the first issues of World Politics, the founding journal of international relations, had numerous articles by historians. For a variety of reasons, the gap widened, but in the sub-field of security studies contact never disappeared, in part because, as Stephen Schuker notes, scholars interested in this subject were marginalized in both disciplines. From my vantage point as a political scientist, it has seemed that the relationship has been less than fully balanced, with our interest in history not being fully reciprocated by our historian colleagues. I remember going to see Raymond Sontag (with whom, Schuker notes, Marc Trachtenberg studied) when I was a graduate student at Berkley to talk to him about my attempt to use history. He was too gracious to visibly wince at the idea of history being used in this way and did make clear that he was glad to see political scientists being interested in history, but it was also clear that he didn’t think we had much to contribute.
The U.S. intelligence failures associated with 9/11 and with Iraqi weapons of mass destruction generated renewed interest in the question of intelligence failure, the study of which had been disproportionately influenced by the study of the failures at Pearl Harbor, Barbarossa, and Yom Kipper. The Iraqi WMD case in particular focused more attention on the question of the politicization of intelligence, an age-old problem but one that had been neglected in studies of the classic cases. The subsequent scholarly literature has focused on the policy question of the proper relationship between intelligence and policy, and on the causal questions of where and when politicization is most likely to occur and the role it plays in the processes leading to intelligence failure.
