The Moral Molecule―The Source of Love and Prosperity

A Revolution in the Science of Good and Evil

Why do some people give freely while others are cold hearted?

Why do some people cheat and steal while others you can trust with your life?

Why are some husbands more faithful than others—and why do women tend to be more generous than men?

Could they key to moral behavior lie with a single molecule?

From the bucolic English countryside to the highlands of Papua New Guinea, from labs in Switzerland to his campus in Souther California, Dr. Paul Zak recounts his extraordinary stories and sets out, for the first time, his revolutionary theory of moral behavior. Accessible and electrifying, The Moral Molecule reveals nothing less than the origins of our most human qualities—empathy, happiness, and the kindness of strangers.

PAUL J. ZAK, Ph.D., is professor of economic psychology and management at Claremont Graduate University. As the founding director of Claremont's Center for Neuroeconomics Studies, he is at the vanguard of neuroeconomics, a new discipline that integrates neuroscience and economics. He has a popular Pyschology Today blog called The Moral Molecule. He makes numerous media appearances, and his research has been featured in The New York Times, The Wall Street Journal, USA Today, Scientific American, Fast Company, and many others.
