David Collier (political scientist)

David Collier (born February 17, 1942) is Chancellor's Professor Emeritus at the University of California, Berkeley. He works in the fields of comparative politics, Latin American politics, and methodology. His co-authored and co-edited methodological work includes "Rethinking Social Inquiry: Diverse Tools, Shared Standards", 2nd expanded edition; "Statistical Models and Causal Inference: A Dialogue with the Social Sciences"; and "The Oxford Handbook of Political Methodology". Collier is engaged in ongoing projects on the challenges of integrating quantitative and qualitative methods and of using this integrated perspective to gain new leverage in conceptualization, measurement, and causal inference.
Career.
At Berkeley, Collier has been Chair of the Political Science Department and of the Center for Latin American Studies, and he was founding Co-Director of the Berkeley-Stanford Program in Latin American Studies. He has served as President of the Comparative Politics Section, American Political Science Association; has been a Vice President of APSA; and was the founding President of the APSA Organized Section for Qualitative and Multi-Method Research. Collier has played an active role in building the Institute for Qualitative and Multi-Method Research, an international training program held annually at Syracuse University. At Berkeley he is centrally involved in training scholars in the fields of Latin American politics, comparative politics, and methodology, and he won Berkeley’s campus-wide Distinguished Faculty Mentor Award.
Collier received a Guggenheim Fellowship and was a Fellow at the Center for Advanced Study in the Behavioral Sciences. He is an elected Member of the American Academy of Arts and Sciences and an elected Fellow of the American Association for the Advancement of Science. In 2014 Collier was awarded the Johan Skytte Prize in Political Science.
Academic research.
Comparative politics and Latin America Politics.
Collier’s early work includes quantitative cross-national research on political regimes, corporatism, and social policy, as well as an exploration of the links between regime change and public policy toward squatter settlements in Peru, which was published as "Squatters and Oligarchs: Authoritarian Rule and Policy Change in Peru" (1976). In his edited volume "The New Authoritarianism in Latin America" (1979), Collier and several leading scholars in the field, such as Guillermo O'Donnell, Albert O. Hirschman, and Fernando Henrique Cardoso, explore alternative explanations for the rise of authoritarianism in Latin America in the 1960s and 1970s. This work brought the literature on Latin American politics in dialogue with the modernization theory dominant in comparative politics at the time. Focusing on the fact that the most industrialized Latin American countries were not the more democratic ones, it articulated several critiques of the prevailing view of Third World politics put forth by modernization theorists (e.g., Seymour Martin Lipset). Thus, at a time when comparative politics sought to provide a general theory of politics in a way that largely disregarded insights developed by regional experts, Collier’s "New Authoritarianism" provided an alternative, demonstrating that area studies could be a site of creative theorizing. Consequently, "The New Authoritarianism in Latin America" was a landmark study in the literature on national political regimes and in the study of politics in Latin America, and is one of the most cited political science texts on this region.
Collier's most sweeping work on Latin America, the fruit of over a decade of research, is "Shaping the Political Arena: Critical Junctures, the Labor Movement, and Regime Dynamics in Latin America" (1991), coauthored with Ruth Berins Collier. This major work makes two fundamental theoretical contributions. The first concerns the linked ideas of (a) critical junctures, periods of crucial change in the history of given countries or other political units that are hypothesized to leave distinctive legacies, and (b) path dependence, the trajectories of change stemming from and constrained by critical junctures. These were, in one sense, not new ideas. The distinctive contribution of "Shaping the Political Arena" was to turn these ideas into a carefully formulated model directly relevant to research in comparative politics; and to then offer a magisterial application of this model to Latin American cases. This book was the first, and still remains, one of the most systematic formulations and applications of critical junctures and path dependency. It convincingly dispelled whatever doubts may have existed about the potentially decisive effect historical events and turning points could have on key political outcomes, from political regimes to democracy to party systems. The lasting effect of Collier’s contribution is evident in many ways. Collier inspired other researchers in the field of comparative politics (e.g., Kathleen Thelen, Paul Pierson, Deborah Yashar, and James Mahoney) to fine-tune and further develop the model presented in "Shaping the Political Arena." Moreover, the applications that draw on Collier’s core ideas about critical junctures and path dependence go beyond political science to economics.
The second theoretical contribution of "Shaping the Political Arena" concerns Latin American politics. In this regard, "Shaping the Political Arena" showed how the way in which labor was incorporated into national political institutions had a major and enduring effect on the subsequent evolution of a country’s party system and political regimes. Counterintuitively, where the role of labor was greater and where it participated more, the resulting political regime was more stable. This argument was examined through an ambitious comparative historical analysis of eight countries over a period of five decades that relied on four paired comparisons. One of the most controversial pairings was Brazil and Chile; this pairing was questioned by many Latin Americanists and experts on labor in Latin America. In retrospect, however, this choice has been vindicated. Nowadays it has become commonplace to see Brazil and Chile as exemplifying a common trajectory with regard to political and economic development. In brief, "Shaping the Political Arena" makes a major theoretical contribution through its elaboration of a critical juncture and path dependency model and also stands as the most ambitious and systematic work on Latin America in the tradition of comparative-historical analysis.
Methodology.
A second strand of Collier’s work focuses on methodology, an area in which Collier has focused attention of setting standards for rigorous qualitative research, as well as multi-method work that combines qualitative and quantitative methods.
One major contribution concerns the centrality of concepts in political science research and the methodological issues of concept formation and conceptual change. Extending the tradition of Giovanni Sartori, Collier makes distinctive, original contributions. In his widely cited “Democracy with Adjectives” (coauthored, "World Politics" 1997), Collier shows how the analysis of concepts can help bring order to research characterized by great conceptual innovation, but perhaps not surprisingly also conceptual disorder. In particular, he shows how the explicit disaggregation of this concept and attention to its internal structure clarifies alternative meanings, and thereby contributes incisively to producing and accumulating knowledge
Collier has also made an important contribution to political science by refocusing attention on typologies. Collier shows that typologies, when used carefully and systematically, can help form the key concepts in substantive research and are also an essential tool for theorizing. Moreover, in various publications, Collier has shown how decisions regarding conceptualization affect measurement, and he has offered guidelines regarding such issues as the choice of indicators and decisions regarding levels of measurement (e.g., whether the concept is operationalized in dichotomous or graded terms). Together, Collier’s ideas add up to a forceful statement for seeing concept analysis as a central challenge in political science research and provide an indispensable guide regarding the methodological tools for tackling this challenge.
Another of Collier’s central contributions concerns qualitative tools for causal inference. Here, central thrusts of Collier’s work have been to put ideas about process tracing on a far more secure footing, and more broadly to codify procedures for qualitative causal inference. This work, published in "Rethinking Social Inquiry: Diverse Tools, Shared Standards" (1st. ed. 2004, 2nd. ed. 2010, coedited with Henry Brady), and in articles in leading journals, challenges the conventional view that statistical tools are always more powerful for causal inference. Most pointedly, Collier makes a strong case that qualitative researchers actually have an advantage over their quantitative counterparts. This advantage derives from the focus on “causal-process observations” in qualitative analysis. These may be defined as pieces of data that provide information about context and mechanisms, and that offer distinctive leverage in making causal inferences. In this work, as in his work on concepts, Collier has been keenly concerned with exploring how qualitative research can be improved by drawing attention to the multiple challenges faced by qualitative researchers. But Collier has also stressed that both quantitative and qualitative researchers face daunting methodological challenges, and this, in turn, requires a more evenhanded assessment of the strengths and weaknesses of both quantitative and qualitative methods.
Another direction of Collier’s work, which springs from the recognition of the shared challenges faced by quantitative and qualitative researchers, has been the exploration of multi-method strategies. Collier’s efforts to move beyond traditional methodological boundaries can be seen most vividly in "Rethinking Social Inquiry" and also in "The Oxford Handbook of Political Methodology" (2008, co-edited with Janet M. Box-Steffensmeier and Henry E. Brady).
