Praise for "Survival of the Nicest"

“This wonderful book could be read as a scientific explanation for a moral imperative to be kind to others. But it is so much more! Stefan Klein, an enticing storyteller, marshals the evidence for the value of altruism—not only to one’s family but, much more interestingly, to one’s self and one’s tribe. Altruism is truly contagious!”

—Roald Hoffmann, Nobel Laureate, poet, and Frank H. T. Rhodes Professor of Humane Letters Emeritus, Cornell University

“A scholarly tour de force about why generosity makes good sense, Survival of the Nicest is also compulsively readable. Klein argues con- vincingly that helping others is one of the best things we can do for ourselves.”

—Elizabeth Svoboda, author of What Makes a Hero?: The Surprising Science of Selflessness

“A thought-provoking and comprehensive review of the research on altruism, Survival of the Nicest validates humanistic principles and has far-reaching implications for today’s world—especially for US politics and culture. An inspiration!”

—Rebecca Hale, president,
American Humanist Association, and co-owner of

“An important contribution to the field of altruism and altruistic behav- ior and to a better and nicer world. I highly recommend this book.”

—Samuel P. Oliner, PhD, Emeritus Professor of Sociology, Humboldt State University, and founder and director, The Altruistic Personality and Prosocial Behavior Institute

“In Survival of the Nicest, Stefan Klein poses three questions central to social science and ethics: (1) How is unselfishness possible? (2) What moves us to help others? And (3) why are some people more helpful than others? His wide-ranging answers to these questions suggest that altruism is born into us and that selflessness actually both makes us happy and will transform the world.”
