Philosopher, neuroscientist, and psychologist, Joshua Greene tells us how the brain generates morality and how his research may have solved the infamous trolley problem, and in so doing created a way to encourage people to contribute to charities that do the most good, and, in addition, play quiz games that can reduce polarization and possibly save democracy.

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 life has thrust the world’s tribes into a shared space, creating conflicts of interest and 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. Here the human brain is revealed to be like 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 human brain’s manual mode is its capacity for deliberate reasoning, which makes our thinking flexible. Our 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, and often with life-and-death stakes. Drawing inspiration from moral philosophy and cutting edge science, Moral Tribesshows us when to trust our instincts, when to reason, and how the right kind of reasoning can move us forward.
The great challenge of Moral Tribes is this: How can we get along with Them when what they want feels so wrong? Ultimately, Joshua Greene offers a surprisingly simple set of maxims for navigating the modern moral terrain, a practical road map for solving problems and living better lives.
Joshua Greene
Joshua D. Greene is Professor of Psychology and a member of the Center for Brain Science faculty at Harvard University.
Originally trained as a philosopher, Greene began his scientific career with behavioral and neuroscientific research on moral judgment, focusing on the interplay between emotion and reason in moral dilemmas (as in “trolley problems”) and social dilemmas involving cooperation.
His current social scientific research examines strategies for expanding our moral circles, with a focus on real-world impact. He is the co-founder of GivingMultiplier, a research-backed donation platform that increases the impact of charitable giving, and the co-creator of Tango, a cooperative online quiz game that reduces animosity and builds trust and respect across lines of division.
His current neuroscientific and computational research aims to understand the “language of thought”, how the brain combines concepts to form complex ideas.
Greene is the author of Moral Tribes: Emotion, Reason, and the Gap Between Us and Them. He teaches Harvard’s General Education course Evolving Morality: From Primordial Soup to Superintelligent Machines.
Greene studied philosophy at Harvard (A.B., 1997) and Princeton (Ph.D., 2002), where he worked with David Lewis and Gilbert Harman. From 2002 to 2006 he trained as a postdoctoral researcher with Jonathan Cohen in the Neuroscience of Cognitive Control Lab and at the Center for the Study of Brain, Mind, and Behavior, which is now the Princeton Neuroscience Institute.
