Understanding politics fully requires expertise in psychology

Evidence

Political psychology explores the border that runs between the intellectual nations of political science and psychology. It is a dynamic subfield that addresses the ways in which political institutions both affect and are affected by human behavior. Our understanding of the reciprocal relationship between politics and psychology (especially social psychology, which borders also on sociology) has been steadily evolving in recent years, making it a compelling and exciting area of study. To know everything there is to know about the world of politics in theory and in practice, one must be, among other things, an expert in psychology. — John T. Jost and Jim Sidanius, Political Psychology, 91
