Social science research often yields conflicting results: Does juvenile delinquent rehabilitation work? Is teenage pregnancy prevention effective? In an effort to improve the value of research for shaping social policy, social scientists are increasingly employing a powerful technique called meta-analysis. By systematically pulling together findings of a particular research problem, meta-analysis allows researchers to synthesize the results of multiple studies and detect statistically significant patterns among them.

Meta-Analysis for Explanation brings exemplary illustrations of research synthesis together with expert discussion of the use of meta-analytic techniques. The emphasis throughout is on the explanatory applications of meta-analysis, a quality that makes this casebook distinct from other treatments of this methodology. The book features four detailed case studies by Betsy Jane Becker, Elizabeth C. Devine, Mark W. Lipsey, and William R. Shadish, Jr. These are offered as meta-analyses that seek both to answer the descriptive questions to which research synthesis is traditionally directed in the health and social sciences, and also to explore how a more systematic method of explanation might enhance the policy yield of research reviews.

To accompany these cases, a group of the field’s leading scholars has written several more general chapters that discuss the history of research synthesis, the use of meta-analysis and its value for scientific explanation, and the practical issues and challenges facing researchers who want to try this new technique. As a practical resource, Meta-Analysis for Explanation guides social scientists to greater levels of sophistication in their efforts to synthesize the results of social research.

Some theorists claim that democracy cannot work without trust. According to this argument, democracy fails unless citizens trust that their governing institutions are serving their best interests. Similarly, some assert that democracy works best when people trust one another and have confidence that politicians will look after citizen interests. Questioning such claims, Democracy and the Culture of Skepticism, by Matthew Cleary and Susan Stokes, suggests that skepticism, not trust, is the hallmark of political culture in well-functioning democracies.

Drawing on extensive research in two developing democracies, Argentina and Mexico, Democracy and the Culture of Skepticism shows that in regions of each country with healthy democracies, people do not trust one another more than those living in regions where democracy functions less well, nor do they display more personal trust in governments or politicians. Instead, the defining features of the healthiest democracies are skepticism of government and a belief that politicians act in their constituents' best interest only when it is personally advantageous for them to do so. In contrast to scholars who lament what they see as a breakdown in civic life, Cleary and Stokes find that people residing in healthy democracies do not participate more in civic organizations than others, but in fact, tend to retreat from civic life in favor of private pursuits. The authors conclude that governments are most efficient and responsive when they know that institutions such as the press or an independent judiciary will hold them accountable for their actions.

The question of how much citizens should trust politicians and governments has consumed political theorists since America's founding. In Democracy and the Culture of Skepticism, Matthew Cleary and Susan Stokes test the relationship between trust and the quality of governance, showing that it is not trust, but vigilance and skepticism that provide the foundation for well-functioning democracies.
