The twenty-first century has seen an exposition of interest in experimental methodology across a wide range of disciplines of scientific investigation. For example, political scientists have become greatly interested in conducting laboratory experiment and field experiments to gain clear insights into causal processes. Furthermore, fields such as psychology have had long-standing interest in and reliance on experimental methodology. However, as simple as the basic principles of experimental design are, the actual detailed design of any one experience can be very tricky business, requiring optimal design of the appropriate control condition(s), procedures to avoid experimental artifacts, measurement designs to identify mediating and moderating variables, and techniques for collecting and analyzing data properly to take into account issues of non-independence, clustering, confounds, and other such complications, and more.
Dr. Krosnick teaches workshops on experimental methodology, providing guidance to beginners and to established and experienced researchers in how to maximize the payoffs from their experiments.
