My favorite books explaining political polarization

Why am I passionate about this?

I’m a Penn State professor of sociology and demography who is interested in social inequality, demography, and public opinion. My family moved frequently when I was growing up—I lived in Colombia, Greece, and Mexico. I attended Brown University and worked at the U.S. Census Bureau as an analyst and Branch Chief for several years before returning to academia. My interest in inequality dates back to living in different countries with different cultures, politics, and standards of living. While I have long been interested in the demographics of poverty and inequality, in more recent years I’ve become interested in political polarization and why people disagree about a variety of social issues.

Why We Disagree about Inequality: Social Justice vs. Social Order

By John Iceland, Eric Silver, Ilana Redstone

Book cover of Why We Disagree about Inequality: Social Justice vs. Social Order

What is my book about?

We argue that people disagree about the best way to address inequality because they are guided by two competing moral and philosophical perspectives—one oriented toward Social Justice and another toward Social Order.

Those with a Social Justice orientation believe that social inequality arises from an unfair social system where those with power exploit others for their own gain. Only far-reaching and rapid change will do in the face of systemic injustice. In contrast, those with a Social Order orientation prioritize social stability and cohesion. Because they trust in the overall goodness of the American system, they prefer slow, incremental change over rapid, foundational change, which they fear can lead to unintended consequences. When it comes to addressing social inequality, neither is “right” or “wrong”—each contains a wisdom the other lacks.

The books I picked & why

Book cover of A Conflict of Visions: Ideological Origins of Political Struggles

John Iceland Why did I love this book?

Liberals and conservatives strongly disagree on the appropriate scope of government. No book has helped me understand why more than Thomas Sowell’s Conflict of Visions.

He describes how the ideological difference results from disagreements about the malleability of human nature. The unconstrained vision, typically associated with liberals, sees human nature as altruistic and perfectible. The government should be used expansively to promote social justice and equality to realize this vision. 

In contrast, the constrained vision, typically associated with conservatives, sees human nature as limited, selfish, and imperfectible. The government should play a limited role in society, as elites cannot hope to restructure society without unintended destructive consequences.

What is this book about?

In this classic work, Thomas Sowell analyzes the two competing visions that shape our debates about the nature of reason, justice, equality, and power: the constrained" vision, which sees human nature as unchanging and selfish, and the unconstrained" vision, in which human nature is malleable and perfectible. He describes how these two radically opposed views have manifested themselves in the political controversies of the past two centuries, including such contemporary issues as welfare reform, social justice, and crime. Updated to include sweeping political changes since its first publication in 1987, this revised edition of A Conflict of Visions offers a…


Book cover of The Righteous Mind: Why Good People Are Divided by Politics and Religion

John Iceland Why did I love this book?

Why do smart, well-meaning people disagree about politics and how do they justify their opinions?

Jonathan Haidt lucidly describes how people rationalize their judgments only after they intuit what is right or wrong. He shows that liberals place a lot of weight on care and fairness, while conservatives balance these concerns with loyalty, respect for authority, and sanctity.

This book made me more cognizant of my own moral reasoning, and how I, like everyone, weigh a variety of such concerns when staking a position on a social issue.

What is this book about?

'A landmark contribution to humanity's understanding of itself' The New York Times

Why can it sometimes feel as though half the population is living in a different moral universe? Why do ideas such as 'fairness' and 'freedom' mean such different things to different people? Why is it so hard to see things from another viewpoint? Why do we come to blows over politics and religion?

Jonathan Haidt reveals that we often find it hard to get along because our minds are hardwired to be moralistic, judgemental and self-righteous. He explores how morality evolved to enable us to form communities, and…


Book cover of The Three Languages of Politics: Talking Across the Political Divides

John Iceland Why did I love this book?

I am often struck by how differently people from across the political spectrum frame any given issue.

Arnold Kling systematically describes this phenomenon and highlights how progressives, conservatives, and libertarians use different language to highlight their concerns. Conservatives focus on threats to traditional values. Progressives highlight threats to the underprivileged. Libertarians worry about threats to freedom.

This book will change the way you consume the news in our polarized media landscape.

1 author picked The Three Languages of Politics as one of their favorite books, and they share why you should read it.

What is this book about?

When it was first released in 2013, Arnold Kling’s The Three Languages of Politics was a prescient exploration of political communication, detailing the “three tribal coalitions” that make up America’s political landscape. Progressives, conservatives, and libertarians, he argued, are “like tribes speaking different languages. As a result, political discussions do not lead to agreement. Instead, most political commentary serves to increase polarization.”

Now available as a newly revised and expanded edition, Kling’s book could not be any more timely, as Americans—whether as media pundits or conversing at a party—talk past one another with even greater volume, heat, and disinterest in…


Book cover of The Blank Slate: The Modern Denial of Human Nature

John Iceland Why did I love this book?

Pinker challenges the widely held belief that human beings are born as blank slates, shaped solely by their environment and experiences.

As a cognitive psychologist, he makes this case with a comprehensive review of the scientific evidence on evolutionary psychological adaptations. I especially appreciate how Pinker conveys a lot of complicated information so plainly. He argues that the belief in the “blank slate” has often led to misguided policies, such as in education and the criminal justice system.

What is this book about?

A brilliant inquiry into the origins of human nature from the author of Rationality, The Better Angels of Our Nature, and Enlightenment Now.

"Sweeping, erudite, sharply argued, and fun to read..also highly persuasive." --Time

Updated with a new afterword

One of the world's leading experts on language and the mind explores the idea of human nature and its moral, emotional, and political colorings. With characteristic wit, lucidity, and insight, Pinker argues that the dogma that the mind has no innate traits-a doctrine held by many intellectuals during the past century-denies our common humanity and our individual preferences, replaces objective analyses…


Book cover of The Revolt of The Public and the Crisis of Authority in the New Millenium

John Iceland Why did I love this book?

Have you wondered why there has been such a dramatic decline in trust in public institutions in recent years?

In The Revolt of the Public, Gurri argues that the rise of digital technology has allowed people to more easily share information and bypass traditional gatekeepers. Gone are the days from my own youth when most people relied on just a few established news sources. People today are more exposed to stories—either real or imagined—of corruption, incompetence, and misinformation from established institutions.

This has contributed to the rise of populism and political extremism, facilitated by social media where people can organize and coordinate their activities.

What is this book about?

How insurgencies-enabled by digital devices and a vast information sphere-have mobilized millions of ordinary people around the world.

In the words of economist and scholar Arnold Kling, Martin Gurri saw it coming. Technology has categorically reversed the information balance of power between the public and the elites who manage the great hierarchical institutions of the industrial age: government, political parties, the media. The Revolt of the Public tells the story of how insurgencies, enabled by digital devices and a vast information sphere, have mobilized millions of ordinary people around the world.

What is my book about?

The constellation we know as Taurus goes all the way back to cave paintings of aurochs at Lascaux. This book traces the story of the bull in the sky, a journey through the history of what has become known as the sacred bull.

Each of the sections is written from the perspective of the mythical Taurus, from the beginning at Lascaux to Mesopotamia, Ancient Egypt, and elsewhere. This is not just a history of the bull but also a view of ourselves through the eyes of the bull, illustrating our pre-literate use of myth, how the advent of writing and the urban revolution changed our view of ourselves, and how even bullfighting in Spain is a variation on the ancient sacrifice of the sacred bull.
