“This book expanded my imagination about what is possible in groups of any form. This expansion came from the careful articulation of multidimensional, multi-evolutionary science and its union with functional behavioral science. The book provides a highly useful and operational approach for building and transforming groups to be more prosocial. This book is chock-full of clear steps on how to engage the prosocial process to increase prosociality in the world. The book is a welcome, practical, and well-documented guide for people interested in lifting up the capability and competence of a group to be more productive, equitable, and collaborative.”

“This groundbreaking book shows how evolutionary theory can be used to empower the success of small groups. It is a seamless integration of the processes of psychological flexibility, the science of organizational development and interpersonal trust, and Elinor Ostrom’s Nobel Prize-winning ‘Core Design Principles’ for group cooperation. What results is a method that is both principle-based and highly flexible, and that speaks directly and practically to the role of coaches and consultants. This book is essential reading for anyone who works with people in group settings, and who is committed to helping these groups to be their best.”

“What do you get when you combine contemporary evolutionary theory, insights from a winner of the Nobel Prize in Economics, and years of psychological research on behavior change? As it turns out, you get a practical and intuitively appealing set of steps for increasing care and cooperation amidst the twenty-first century’s soul-sapping and ecologically damaging selfishness. The approach developed by Atkins, Wilson, and Hayes shows real promise, and I hope many people adopt it.”
