Praise for the Second Edition: The new edition of Rethinking Social Inquiry is, quite simply, the best treatise yet on the intersection of qualitative and quantitative methods. The book places causal-process tracing on a new foundation and provides a framework for skeptically evaluating natural experiments. The discussions are conceptually, statistically, and historically rigorous; the examples will have broad appeal.
