“Surprising and remarkable… Toggling between big ideas, technical details, and his personal intellectual journey, Greene writes a thesis suitable to both airplane reading and PhD seminars.”


Our brains were designed for tribal life, for getting along with a select group of others (Us) and for fighting off everyone else (Them). But modern times have forced the world’s tribes into a shared space, resulting in epic clashes of values along with unprecedented opportunities. As the world shrinks, the moral lines that divide us become more salient and more puzzling. We fight over everything from tax codes to gay marriage to global warming, and we wonder where, if at all, we can find our common ground.

A grand synthesis of neuroscience, psychology, and philosophy,
Moral Tribes reveals the underlying causes of modern conflict and lights the way forward. Greene compares the human brain to a dual-mode camera, with point-and-shoot automatic settings (“portrait,” “landscape”) as well as a manual mode. Our point-and-shoot settings are our emotions—efficient, automated programs honed by evolution, culture, and personal experience. The brain’s manual mode is its capacity for deliberate reasoning, which makes our thinking flexible. Point-and-shoot emotions make us social animals, turning Me into Us. But they also make us tribal animals, turning Us against Them. Our tribal emotions make us fight—sometimes with bombs, sometimes with words—often with life-and-death stakes.

An award-winning teacher and scientist, Greene directs Harvard University’s Moral Cognition Lab, which uses cutting-edge neuroscience and cognitive techniques to understand how people really make moral decisions. Combining insights from the lab with lessons from decades of social science and centuries of philosophy, the great question of
Moral Tribes is this: How can we get along with Them when what they want feels so wrong to Us?

Ultimately, Greene offers a set of maxims for navigating the modern moral terrain, a practical road map for solving problems and living better lives.
Moral Tribes shows us when to trust our instincts, when to reason, and how the right kind of reasoning can move us forward.

A major achievement from a rising star in a new scientific field,
Moral Tribes will refashion your deepest beliefs about how moral thinking works and how it can work better.

Editorial Reviews

From Booklist

The human brain processes morality automatically, influenced by evolution, culture, and experience but with a capacity for deliberate reasoning that allows for nuance, much needed in our increasingly complex world. Greene, a philosopher and scientist, draws on research in psychology and neuroscience to explore the roots of morality, particularly the tragedy of commonsense morality, when people of different races, religions, ethnic groups, and nationalities share the same sense of morality but apply it from different perspectives in whose differences lie the roots of conflict. Us-versus-them conflicts date back to tribal life. Greene analyzes the structure of modern moral conflicts on a wide spectrum of issues, from global warming to Obamacare to economic policy, and also the structure of our “moral brains.” Conflicts stem from a lack of moral philosophy, a problem pondered by philosophers since the Enlightenment. Greene ends with a vision of universal moral philosophy, a “metamorality” that crosses, racial, religious, ethnic, and national boundaries. Greene’s strategies for examining moral reasoning are as applicable to day-to-day decisions as they are to public policy. This is a highly accessible look at the complexities of morality. --Vanessa Bush

Review

Robert Wright, The Atlantic:
“[Greene’s] concern is
emphatic, his diagnosis precise, and his plan of action very, very ambitious. The salvation of humankind is possible, but it’s going to take concerted effort… [a] rich, sprawling book."

The Boston Globe:
"
Surprising and remarkable… Toggling between big ideas, technical details, and his personal intellectual journey, Greene writes a thesis suitable to both airplane reading and PhD seminarsMoral Tribes offers a psychology far beyond the realm of self-help, instead probing the intricacy and complexity of morality in an attempt to help, and perhaps unite, entire communities."

Robert M. Sapolsky, The Wall Street Journal:
“Superb."

Christian Perring, Metapsychology:
“More interesting than its defense of Utilitarianism is the fact that
Moral Tribes is one of the first attempts to bring experimental philosophy to a wider audience. Making technical philosophy accessible to a wider group is something that academic philosophers have not done enough. Greene provides a fascinating glimpse of what it might be to do scientifically informed moral philosophy.”

Sasha Pfeiffer and Anthony Brooks, WBUR:
“Joshua Green has a fascinating new book about how we make moral decisions. With a deep knowledge of philosophy and using brain scan science, the Harvard psychologist probes some big questions. Questions like why is it we’re capable of putting the welfare of our communities above our own personal welfare?  In other words we’re pretty good at making tribal life work, but then why do groups of people: sports fans, political partisans, religious believers, Americans, have so much trouble getting along with other groups? The question is hugely important in this modern world when conflicts among political parties, religious faiths and nations have dramatic consequences. It’s at the core of Joshua Greene’s new book.”

Thomas Nagel, New Republic:
“Joshua Greene, who teaches psychology at Harvard, is a leading contributor to the recently salient field of empirical moral psychology. This very readable book presents his comprehensive view of the subject, and what we should make of it. Greene offers much more experimental detail and some ingenious psychological proposals about why our gut reactions have the particular subtle contours that they do.”

Publishers Weekly:
“With a humorous, relaxed tone, Greene stacks piles of evidence from well-researched studies onto his theory of modern-day morality. Having spent most of his academic career on the study of morality, Greene foresees the questions his readers have and systematically addresses every doubt and concern. As he mixes 20th-century philosophical moral treatises with neuroscience and psychological studies—many of which were undertaken by his colleagues in the field of moral psychology—Greene’s role as educator shines through; his writing is clear and his examples simple yet intriguing.”

Vanessa Bush, Booklist:
“Greene’s strategies for examining moral reasoning are as applicable to day-to-day decisions as they are to public policy. This is a highly accessible look at the complexities of morality.”

Kirkus Reviews:
"A
provocative, if Utopian, call for a new 'common currency of observable evidence…not to gain advantage over others, but simply because it’s good.'”

Daniel Gilbert, professor of psychology, Harvard University; author of the international bestseller Stumbling on Happiness:
“Joshua Greene is the rarest of birds—a brilliant scientist and equally brilliant philosopher who simultaneously takes on the deepest problems of both disciplines. More than a decade in the making,
Moral Tribes is a masterpiece—a landmark work brimming with originality and insight that also happens to be wickedly fun to read. The only disappointing thing about this book is that it ends.”

Robert Sapolsky, John A. and Cynthia Fry Gunn Professor of Biological Sciences, Stanford University:
“A decade ago, the wunderkind Joshua Greene helped start the field of moral neuroscience, producing dazzling research findings. In this equally dazzling book, Greene shows that he is also one of the field’s premier synthesists. Considerable progress has been made in solving the classic problem of how to get individuals within a group to start cooperating. Greene takes on an even bigger problem—how to foster cooperation between groups, groups with deeply felt morals and values, but with different morals and values. There are few more important issues to solve in our increasingly pluralistic world, and this beautifully written book is a step in that direction.”

Peter Singer, professor of bioethics, Princeton University:
“Over the past decade, Greene’s groundbreaking research has helped us understand how people judge right and wrong. Now, in this brilliant and enlightening book, he draws on his own research and that of many others to give a more complete picture of our differences over moral issues. But the significance of this book goes far beyond that. Greene suggests a common moral currency that can serve as a basis for cooperation between people who are otherwise deeply divided on matters of morality. If our planet is to have a peaceful and prosperous future such a common moral currency is urgently needed. This book should be widely read and discussed.”

Steven Pinker, Harvard College Professor of Psychology, Harvard University; author of How the Mind Works and The Better Angels of Our Nature:
“After two and a half millennia, it’s rare to come across a genuinely new idea on the nature of morality, but in this book Joshua Greene advances not one but several. Greene combines neuroscience with philosophy not as a dilettante but as an expert in both fields, and his synthesis is interdisciplinary in the best sense of using all available conceptual tools to understand a deep phenomenon. Moral Tribes is a landmark in our understanding of morality and the moral sense.”

    “Moral Tribes” by Joshua Greene is a brilliant, deeply insightful exploration of how humans think about right and wrong—and what we can do when our instincts fall short in an interconnected world.

    Greene, a Harvard neuroscientist and philosopher, takes readers on a sweeping journey through moral psychology, combining cutting-edge brain science with moral philosophy to address one of the most urgent questions of our time: How can groups with different moral values coexist peacefully in a global society? His core metaphor of the “tragedy of commonsense morality” is both elegant and haunting—it explains why morality works so well within tribes, yet so often fails between them.

    What I found particularly compelling is Greene’s dual-process theory of moral reasoning: our automatic, gut-based responses (like outrage) versus our slow, deliberate reasoning (like utilitarian calculus). Rather than dismiss one in favor of the other, he offers a framework to balance them, making a strong case for a metamorality based on utilitarian principles—not to erase differences, but to navigate them more wisely.

    Greene writes with clarity, humor, and humility. He doesn’t shy away from controversial topics, but he tackles them with nuance and compassion. Whether you’re a student of ethics, a policymaker, or just someone trying to make sense of today’s divided world, this book will challenge and enlighten you.

    Highly recommended for anyone ready to think more deeply about what it means to be good in a complex, pluralistic world.

    Neuroscieintist/philosopher Joshua Greene has a big thesis in this book that requires some quite involved steps. His concern is to argue for a "metamorality" of the kind that should help groups with differing moralities resolve differences. Greene starts out envisioning two prototypical "tribes. One has a morality of self-reliance and "just desserts," where people are responsible for their lot in life and get rewarded in proportion to their efforts. The other has a more altruistic view of the world, where things are shared and shared alike, and everyone feels responsibility for everyone. The question: how do we decide which of these groups - or more likely, which elements of each group's worldview - should win the day in cases of moral conflict? (More specifically: when we face moral dilemmas where we could respond via self-interest and "just desserts" or with altruism and egalitarian "desserts", how should we determine which to go with?)

    Greene's answer is basically a form of utilitarianism that he calls "deep pragmatism." And to see why requires some explanation, which could be really dull but isn't, owing to Greene's gifts as a good and clear writer. He argues that humans have what is called a "dual process morality" that is divided between intuitive gut instincts (dominated by the ventromedial prefrontal cortex) and a more calculating thought process (owing more to the dorsolateral prefrontal cortex). When it comes to questions of "me versus us," the intuition side of things is pretty reliable, making us feel guilty for taking more than "our fair share," breaking rules that we expect everyone else to follow, etc. Understandable, because our intuitions of empathy and the like almost certainly evolved to stimulate cooperation within groups among otherwise selfish individuals (which confers an overall survival advantage).

    But our instincts also don't do very well with "we versus them" problems, because the same mechanisms that evolved to stimulate cooperation evolved to do so only WITHIN GROUPS (not between them). So, instincts often make us feel guilty at not helping others who are close to us, but the guilt lessens the farther removed the others-in-need are from us. Here, though, the thinking part of our brains can step in, and the thinking part of our brains (Greene's and others' research suggests) tend to be "utilitarian" - preferring whatever option leads to the greatest overall happiness less discriminately.

    The most interesting (and original) parts of this book are those where Greene reviews his own and others' research on "the trolley problem" - a problem philosophers have concocted to illustrate the dilemma between the sanctity of individual rights and the imperative of maximizing overall happiness. The trolley problem - and there are many variations of it - is of a train going down a track where five people are trapped. One can avert the trolley from killing the five only if one pushes a particular person onto the track (fortunately, you are standing at an area of the track where any obstruction to the trolley will avert it to a side-track, and pushing the man in front of the track will create such an obstruction.)

    Yes, it is highly contrived, but philosophers have argued for many years over the 'correct' answer to the problem: is it better to maximize happiness by saving five even if it means you have to intentionally sacrifice one, or is it better to let the five die if it means not intentionally killing one innocent person? Greene's study has led him to see the "dual process theory" of morality at work here. Those who have damage to the "instinctual" part of the brain unhesitatingly kill the one to save the five, and those with damage to the "calculating" part of the brain do the opposite. The rest of us struggle because the two parts of our brain are telling us different things.

    But, far from saying that there is no good answer, Greene suggests that in the trolley case, the best answer is the utilitarian one, because he suspects that our compunctions about intentionally killing to save five lives is a relic of the intuitional module of our brain (as evidenced partly by the fact that those who choose to let the five die can''t generally give any good explanation for why, save that it feels wrong). And Greene also suggests that while intuitional thinking doe serve us well at times - in "me versus us" questions - it is often ill-equipped to deal with "us versus them" problems (problems the world is facing more and more of).

    This is where I start to find Greene unconvincing. Without getting into too much detail, Greene strikes me as a utilitarian only to the degree that it gets him to the answers he wants to get... and there is a lot of inconsistent reasoning Greene gives about why utilitarianism is the best actual theory, rather than the one that gets him the answers he likes best. Mostly, this comes from a mixture of explaining both how utilitarianism doesn't conflict with some of our most deeply held intuitions (disrespect for individual rights when they conflict with the greatest good, etc), AND explaining that when it does, it is because in those cases, our intuitions are wrong. In other words, when utilitarianism validates our intuitions, that shows how good utilitarianism is, but when it conflicts with our intuitions, that shows that our intuitions - not utilitarianism - is flawed. Something seems very post hoc and inconsistent about this.

    To be sure, I don't have a much better answer. I think that, in the end, Greene's work actually REDUCES our confidence that there are best and worst answers to moral questions, but that is because unlike Greene, I see no reason to think we can resolve the "dual process" competing answers by somehow stepping above our human moral thinking and saying that there is an objective criteria that can determine which "process" is the right one and which, the wrong one. Might it just be that our impulses toward intuition and calculation conflict and that is that? Yes, Greene (and many of us) do think that it is quite important to produce the greatest happiness for the greatest number, but if our instincts about what is morally right can be flawed in some cases, why can't our feeling that the greatest good is important be flawed too (and even though we reason to it, the value we put on the greatest good is still an instinct)? Not that Greene is wrong to put value on it, but I came away thinking that he wanted it both ways: intuitions can be trusted when they validate our calculations, but they're probably wrong when they don't.

    Anyway, aside from my general misgivings about Greene's conclusion (or at least his defense of it), I thoroughly enjoyed this book. Greene's research on the neural basis of moral thinking is intriguing, original, and does a service to moral philosophy. And here, he writes a clear and well-written explanation of those and a larger moral case he draws from it. Those who are interested in this book should also read Braintrust: What Neuroscience Tells Us about Morality, and The Righteous Mind: Why Good People Are Divided by Politics and Religion (Vintage).The Moral Landscape: How Science Can Determine Human Values

    I really enjoyed reading "Moral Tribes," but I am already a fan of Jonathan Haidt's work so I knew going in that I would most likely enjoy this book. I only want to make one comment about "Moral Tribes" and it is a criticism, but I still think this is an excellent work.

    Towards the end of his book, Greene spends several pages *in the footnotes* discussing the central argument in John Rawls' "A Theory of Justice." Greene criticizes Rawls for constructing unrealistically risk-averse hypothetical people behind The Veil of Ignorance because what Rawls *really* wants is "a society in which priority is given, as a matter of first principles, to people with the worst outcomes." In other words, Greene accuses Rawls (and Kant too in an early chapter) of twisting himself into pretzel shapes in order to arrive at a pre-ordained conclusion. In the case of Kant and the ridiculous prohibition on masturbation, it is the sentiments of 19th-century Lutherans, and in the case of Rawls it is a center-left welfare state favored by his fellow reasonable professors at Harvard in the mid-to-late twentieth century.

    I actually think that is a fairly valid criticism. And yet Greene himself spends that latter parts of the book doing exactly the same thing. He twists himself into pretzel shapes in order to convince us that his utilitarianism would not support slavery in any form (a fairly unconvincing part of the book), nor would it require us to become "happiness pumps" for the less fortunate. How convenient! Once again, an author points forth an elaborate argument that leads pretty much to the conclusion that the currently held beliefs of his audience (or in my case as a liberal, Bay-area, white, male, tech worker) are pretty much good-to-go. No need to worry about Greene's "deep pragmatism" leading to sex slavery or too many painful sacrifices to the poor and dispossessed of the earth. Lucky me! Say what you want about Peter Singer's utilitarianism, but that man challenges me. The same can't be said of Greene.

    I'm kinda being a snot about this, but I really enjoyed the book and if you've read this far into my review I would just say buy it and decide for yourself.

    5.0 out of 5 stars It‘s definitely worth reading this book
    Reviewed in Germany on March 12, 2018
    Everyone who is interested in questions concerning the modern life which is characterized by the co-living of people of various interests and beliefs should read this book.
    Greene has managed to convey complicated knowledge in easy-to-digest words to his readers, though it is still challenging to understand part of the content, especially the part which asks you to question your own emotions and instincts.
    But if you manage to look into your own emotions and instincts instead of just being lead by them, you’ve really achieved a lot and got the most out of this book.
    While I fully endorse Greene’s idea that it's essential for inter-group dispute to shift to the manual mode and to be aware of one’s desire to only use the manual mode for rationalizing one’s own emotion/feeling/belief, I do think that one should listen a little bit more carefully to the voice of one’s feeling than Greene suggested.
    Although I’m an economist and embrace utilitarianism from the beginning (Greene’s explanation of utilitarianism is the best one I’ve ever seen, in economics, we’ve actually only borrowed a small part of utilitarianism as a philosophy, so I don’t think I can explain it better), I don’t think that to push someone off bridge to rescue five on the rail in the trolley dilemma is a good idea. Even if I think about it without emotion, I still think that if someone goes on rail then he should take into account that a trolley may arrive even if he’s assured that it won’t happen. And when someone stands on bridge, he should not steadily fear that someone may push him off. Utilitarianism aims for the maximization of positive experiences of all people, then sacrificing one life for five lives is not necessarily the right choice if it alters the existing behavior rule and leads to a situation in which everyone ever passing a bridge would have to look around if someone is trying to kill him, maybe for a good purpose.
    I endorse Greene’s idea that the manual mode and its corresponding philosophy, the utilitarianism, is the best way to solve the commonsense morality problem, namely when co-living groups differ in their beliefs. But the manual mode is a complicated device, even if two think completed rationally and impartially, they may draw different conclusions, not only in the case of trolley dilemma. Given our limited capacity of rational thinking, the idea of right may still be useful when it’s about action recommendation on the common pasture, since as a rationalization of feelings, it already contains lessons learnt from the biological, cultural and personal history, in which not only individuals lived in groups but also groups merged and split. Of course, when two rights contradict each other, we have to switch to utilitarianism if we don’t want to fight forever.
    If it’s not about action recommendation, but about the research, I have somehow the instinct that researchers can find out more, if they manage to combine utilitarianism and the theory of rights. But I’m no philosopher, so it’s just a speculation.
    In point of mathematics I also differ with Greene. I thought mathematics is not used to derive the truth but to describe the relationships. The result of proof is always conditional, so the truth of a theorem always depends on the truth of theorems it’s based on. If there would be a parallel universe in which some of the axioms no longer hold, then all theorems derived from them would have to be reconsidered. But this is more a theoretical point than a practical one, and possibly results from our different academic background and the literature we survey.
    Taking all together: I highly recommend this book to you.

    5.0 out of 5 stars Fantastic - a book that was waiting to be written
    Reviewed in the United Kingdom on January 18, 2014
    A superb summary and fusion of 2,500 years of moral philosophizing and the scientific advances in evolutionary sciene of the past 150 years. Surely, this must represent the conclusions drawn by any thinking person regarding ethical questions in politics? Deep pragmatism as the ultimate philosophy of the Last Man. Steven Pinker has called this 'a landmark in our understanding of morality', and one cannot but agree!

    Greene carefully debunks all the false and superficial objections to utilitarianism (most of the time based on misinterpretations of 'extreme case scenarios, such as the so-called 'trolley problem'), as well as the fallacies of the rule worship of deontogical theories. (Eg those still clung to by Haidt and others.)

    There is also a nuanced and comprehensive discussion of the scientific advances in evolutionary psychology/ economic psychology of recent years. A must read for all utilitarians and those interested in economic psychology!

    Ótimo livro para compreender como nossa natureza pode produzir o conflito entre tribos que não se entendem e não querem se entender. Mas também como superar essa divisão. Altamente recomendado.

    5.0 out of 5 stars Quand la biologie rencontre la morale
    Reviewed in France on January 26, 2020
    En lisant Behave de Sapolsky, je me suis beaucoup intéressé a la question de la morale, d'un point de vue neuroscientifique. J'ai donc fait l’acquisition de Moral Tribes et de Us & Them, tous très consistants pour approfondir et comprendre le raisonnement de Sapolsky. Pendant longtemps les philosophes se sont questionnés sur la morale, ou l’idée d'une morale "absolue", sans pour autant avoir le savoir et les technologies nécessaires pour comprendre le cerveau humain d'aujourd'hui, et ce qui l'a façonné (il y a plusieurs dizaines d’années).

    L'auteur annonce que certaines parties sont plus complexes que d'autres, mais je pense qu'il faut juste s'accrocher et prendre le temps de se demander si on a compris chaque étape. L'anglais est relativement facile, si vous avez un niveau correct, il ne posera aucun problème, il n'y a pas de mots qui vous demanderont un traducteur a toutes les pages.

    5.0 out of 5 stars Philosophers and lawyers should read this!

    This book is one of the best books I've ever read on human morality based upon scientific findings. Without neuroscience and evolutionary theory, debating on morality is worthless.
    All lawyers and philosophers, including the majority of self-righteous grandiose philosophers, should read this eloquent defense of utilitarianism.
    "Our gut reactions were not designed to form a coherent moral philosophy. Thus, any truly coherent philosophy is bound to offend us, sometimes in the real world but especially in the world of philosophical thought experiments, in which one can artificially pit our strong feelings against the greater good." (p.349)
    "When we appeal to rights, we're not making an argument; we're declaring that the argument is over." (p.351)
    I wish the author talked more about cardinality of utility, interpersonal comparison of utility, and the ultimate function of "happiness."
