It improves cooperation within the group, helping its members balance personal interests with the interests of the collective. The basic principles of group organization and behavior change techniques provided by the prosocial process help coordinate between groups, allowing for the creation of more effective systems of collaboration at regional, national, and global levels.

Whoever you are - a business owner, a head of an educational institution, a volunteer in your city, or a community activist - you surely understand the immense opportunities that groups have in bringing about grand changes in our world. But how exactly are effective and productive groups formed, and how is their sustainability ensured? Drawing on the work of Nobel Prize laureate economist Elinor Ostrom and utilizing the achievements of contextual behavioral science and evolutionary science, the authors of this groundbreaking book have essentially created a step-by-step guide to forming groups that possess qualities such as harmonious relationships among group members, low turnover, and longevity, i.e., all that is the key to sustained success. Prosocial represents a practical and comprehensive program for organizing effective and socially just groups of any size, as well as a program for managing newly formed groups, groups in conflict, or networks of groups. In this guide, you will find descriptions of strategies for strengthening relationships with other groups or business partners and recommendations for setting goals for groups. Most importantly, you will learn how to strengthen cooperation among group members, which is one of the most important conditions for forming an effective group.
