Predisposed: Liberals, Conservatives, and the Biology of Political Differences 1st Edition
Purchase options and add-ons
Buried in many people and operating largely outside the realm of conscious thought are forces inclining us toward liberal or conservative political convictions. Our biology predisposes us to see and understand the world in different ways, not always reason and the careful consideration of facts. These predispositions are in turn responsible for a significant portion of the political and ideological conflict that marks human history.
With verve and wit, renowned social scientists John Hibbing, Kevin Smith, and John Alford―pioneers in the field of biopolitics―present overwhelming evidence that people differ politically not just because they grew up in different cultures or were presented with different information. Despite the oft-heard longing for consensus, unity, and peace, the universal rift between conservatives and liberals endures because people have diverse psychological, physiological, and genetic traits. These biological differences influence much of what makes people who they are, including their orientations to politics.
Political disputes typically spring from the assumption that those who do not agree with us are shallow, misguided, uninformed, and ignorant. Predisposed suggests instead that political opponents simply experience, process, and respond to the world differently. It follows, then, that the key to getting along politically is not the ability of one side to persuade the other side to see the error of its ways but rather the ability of each side to see that the other is different, not just politically, but physically. Predisposed will change the way you think about politics and partisan conflict.
As a bonus, the book includes a "Left/Right 20 Questions" game to test whether your predispositions lean liberal or conservative.

Review
"Just fascinating."
―Taegan Goddard, Political Wire
"From beer-swilling fruit flies to defense-obsessed Republicans, Predisposed reveals why we differ politically and how we can bridge this chasm in an entertaining read by the leading bio-political scientists."
―Paul J. Zak, PhD, author of The Moral Molecule: The Source of Love and Prosperity"This is a must read book for anyone – general reader or scholar – interested in politics and concerned about contemporary political polarization. This work is non-partisan, deeply researched, well-written, and highly informative. It is a book to send to others you know who, like these authors, want democracy to actually work better, since that is not likely to happen until we truly appreciate the nature of our varying political views. Over time, issues will change but our biological predispositions will not, nor will our political differences. When you have completed this book you will appreciate why this is true, and that since this is the way it always has been, and will be, we should deal with it."
―John W. Dean, former Nixon White House counsel and author
"I don't know if John Hibbing, Kevin Smith, and John Alford are correct that understanding the psychological and physiological differences between liberals and conservatives will help to ameliorate ideological conflict, but I hope so. They have, in any case, written the most reasonable, accessible, fun, constructive, and down-to-earth account of scientific research on political orientation to date. Forget the sensationalistic blogs and read this book instead!"
―John T. Jost, Professor of Psychology and Politics, New York University"We should all be predisposed to like this book. These authors have offered a thoughtful, interesting, and intriguing argument about our political predispositions. My fondest hope is that this accessible book will spark a much needed debate about how to think about the origins and causes of political behavior. That debate would help us break out of the existing approaches that have shaped our thinking for far too long. Not everyone will appreciate what is said in these pages. But whether or not you like these ideas, the book is both enjoyable and thought-provoking."
―John Geer, Professor of Political Science and Public Policy, Vanderbilt University, andauthor of In Defense of Negativity
"Hibbing, Smith, and Alford have written a landmark book on our newfound understanding of the role biology plays in politics. It is both important and fun to read, with lovely stories and juicy tidbits from the latest research. I couldn't tear myself away! This is the kind of book that will change the way everyone thinks about both politics and what it means to be human."
―James H. Fowler, author of Connected: How Your Friends' Friends' Friends Affect Everything You Feel, Think, and Do"How do small biological differences map onto political postures? This stunning book takes into account the complexity of the world while teasing out the subtle patterns that make our truths so varied. An extraordinary work: balanced, nuanced, illuminating."
―David Eagleman, Professor of Neuroscience and Psychiatry, Baylor College of Medicine, bestselling author of Incognito and Sum"A wonderful example of theoretically informed experiments demonstrating the genetic, physiologic, and cognitive underpinnings of political predispositions. Biopolitics has come of age."
―Milton Lodge, Distinguished University Professor of Political Science, SUNY at Stony Brook"Destined to cause a stir, this book is by far the best source for what has emerged as an important new wave in the study of mass politics. In exploring how differences in people's biology, physiology, and cognitive makeup map onto politics, it provides a bracing sense of just how deeply our political differences run. Accessibly written and rigorously argued, it will provide a fascinating read for anyone interested in politics."
―Marc J. Hetherington, Professor of Political Science, Vanderbilt University"We have known that we are political animals for a couple thousand years, but Predisposed provides critical clarity about how our biology influences human politics. At the same time, the authors dispel unfounded misconceptions that biology is destiny. The mix of cutting-edge science with humorous writing makes this book a fantastic read!"
―Darren Schreiber, Professor of Politics, University of Exeter"This book will not make politics easier but it will make it easier to understand. The authors’ analysis will be especially valuable for those men and women who want to use our freedoms to make our union more perfect."
―U.S. Senator Bob Kerrey
"The reviews are clearly presented, making the nature of studies and results accessible to nonexperts. The book includes the "Left/Right 20 Questions Game" for readers to test their own predispositions." Summing Up: Recommended. Undergraduate collections. - J. M Stonecash, emeritus, Syracuse University, in CHOICE

The book’s takeoff point is the differences between liberals and conservatives. The authors contend that these people see the world in a fundamentally different way—and are unlikely to, through reason, change the views of the other. Using questionnaire items identifying “What works best” lays out the differences (see the survey items on page 53). Conservatives are more apt to respect tradition, to believe that external codes should guide behavior, to accept that leaders should stick with their values no matter what, understand that then world is a dangerous place and one always has to be ready to defend oneself, and accept that those who do bad things need to be punished. Moreover, society works best when leaders are obeyed, when leaders call the shots, and when leaders adhere to their principles no matter what. Liberals? Pretty much the opposite. In other words, liberals and conservatives see and live within different worlds. And—an important point—twin studies suggest that there is a genetic component to these differences.
In this book, unlike some others, the authors do not choose one worldview over the other; their aim is to demonstrate that Ls and Cs live in different worlds (unlike the ubercritical work “The Republican Brain”). Many more differences are put forward.
Also, biological aspects of these differences are discussed, including underlying genetics. What would be the reason for genetic differences here? The authors have a ready explanation for this. Whether or not readers will accept that is a separate story. But their hypothesis is certainly reasonable. There is also a lucid description of how the human brain might come into play here.
As noted at the outset, this is an important book. The authors take much data that they have access to and make a credible presentation as to the nature of differences between Liberals and Conservatives and some possible bases for these distinctions. If interested in the biology of political differences, this is a good starting point.
There is a discussion of the meaning of predisposition, but generally it can be “thought of as biologically and psychologically instantiated defaults that, absent new information or conscious overriding, govern response to given stimuli.” A brilliant definition, I think. In chapters two and three, the authors make the case that politics is universal and human nature is variable. In chapters four to seven, we are presented with “empirical evidence documenting the deep-seated psychological, cognitive, physiological, and genetic correlates of political variation.
We are introduced to a principle called bedrock social dilemmas, and the authors show us that differences regarding these have existed as long as humans have been living in social groups. One chapter is devoted to explaining individual differences and why they’re important. It seems that innate attitudes may exist in people and that people are just not dispositionally the same when it comes to work ethic, recreational or occupational pursuits, etc. Can it be that differences in attitudes are shaped by biological and cognitive dispositions? In other words, are predispositions biologically measurable and do they connect to generic psychological and cognitive patterns? In ensuing chapters, the authors explore how “politically relevant predispositions can be glimpsed on four separate but interlocking levels: psychological orientations and tastes, patterns of cognition, physiopsychological response, and genetics.” The authors ultimately conclude that people experience and process different worlds. They argue that biology (which is more than just genetics) predisposes people to certain tastes and preferences because individual differences (discussed in detail in the book) are a consequence of the biological machinery that differs from one person to the next. Simply put, “We have different personalities, moral foundations, and personal values – and we have different politics.” These conclusions are fortified by various tests performed on subjects such as, gaze cuing test, categorization tasks, the Stroop Task, Dot-Probe Task, and the Flanker Task. The authors do caution, however, that “exceptions are plentiful for all social science results, as well as most in the natural sciences, and the results we report are no different.”
In chapter six, we learn about the work by scientists in the field of psychophysiology. Unbelievably, components in the brains of individuals differ based on whether they are liberal or conservative in a statistically significant way. For example, the anterior cingulate cortex (ACC) and the amygdala differ based on ideology. In a subsequent chapter, we see the role of genetics in affecting ideological dispositions. Again, the authors caution “that none of these studies suggests that genes by themselves determine ideology, as they all leave plenty of room for socialization, culture, and unique life experiences.”
By chapter eight, the authors tackle the question of why these differences exist. In this chapter we see how evolutionary processes can lead to stable and heritable personality traits both in the animal world and in humans. Now we’re throwing around terms such as, heritability coefficients, homozygous, heterozygous, frequency dependence, genetic variation,and natural selection. Using what one can learn about evolutionary process, one can offer “plausible explanations of the origins of variations in political predispositions.” To be more precise, “downstream behavioral syndromes … might stem from modular genetic forces that are then amplified by (usually) supportive environmental experiences to create remarkable intraspecies variation in a range of behaviors, including those pertinent to human mass-scale politics; in other words, to create predispositions.” This premise is fully explored in the book.
The final task the authors set for themselves is an understanding of how politically relevant physiological and deep psychological differences could actually improve our lives in the twenty-first century. Can conservatives and liberals survive together? The authors try to show that the answer to that question is yes.
