The joint effort society is a new political engagement model. One reviewer stated: 'JES! is more of a manifest or at least a book filled with ideas how to shape society. Fascinating, ambitious and worth reading.' This book shows how decisionmaking, behaviour and institutionalization / technology can contribute to a rising level of wellbeing for all people. It also describes how to create a joint effort society, where all individuals are equal and freely associate into the new political engagement model that is rooted in open and connected local communities, allowing individuals to engage, participate and learn. The approach that leads towards a joint effort society is called ecolution. It involves a transition towards a higher ecological, economic, social and psychological level that takes the wellbeing of 7 billion people into account each time we act. The theory of ecolution offers a new conceptual framework, toolbox and method in the form of a dynamic matrix. It supports growing awareness and inspires to different thinking and acting. JES! is the follow-up of the thesis Allemaal Winnen (Only Winners), 2012 Authors: Frank van Empel & Caro Sicking Bron: Flaptekst, uitgeversinformatie
