"[T]his is a well-written and enjoyable book that fills a clear need in the literature. It will make an excellent addition to any course on research design and will serve as a useful reference for anyone interested in this methodology. Quite frankly, given the strong case Mutz makes for population-based survey experiments, it is hard to imagine why any social scientist would not be interested in using this method."--Eric W. Groenendyk, Public Opinion Quarterly
