Rarely do they produce a work as carefully thought out as that which Morgan Marietta and David C. Barker present in One Nation, Two Realities...The book clearly contributes to multiple domains of research, including work on misperception, polarization, values, motivated reasoning, epistemology, and more. It is worth reading for students, researchers, and citizens concerned by divisions in American society and can provide much needed depth to public discussions of an ever-increasing problem.
