Why We’re Polarized

Vox Media cofounder Klein explores political polarization in the U.S., from its psychological underpinnings to its impact on congressional lawmaking, in this timely, thought-provoking debut. Klein’s multifaceted approach draws on the work of political scientists, media critics, and social psychologists to address why individuals choose allegiance to party over policy, the pros and cons of identity politics, and the inherent instability of a presidential republic, among other topics. His pithy assessments (“The smarter the person is, the dumber politics can make them”) hit the mark more often than not, and political junkies as well as general readers will learn from his analysis of the U.S. media landscape. Klein provides unique insight into how journalists decide what stories to cover, and how that process contributes to a closed feedback loop in which efforts to persuade are less appealing to audiences than content that stokes partisan feelings. Klein’s modest set of principles for how the electoral system might “function amid polarization” may disappoint readers looking for more comprehensive solutions, but his thoughtful, evenhanded outlook fits the seriousness of the subject. This precise and persuasive guide helps to make sense of the current state of American politics. (Jan.)
