Wisdom in groups is earned by gathering useful data, exploring diverse perspectives, respecting different viewpoints, and then shaped through critical reflection on behalf of tangible outcomes.

Collective wisdom is about our capacity to recognize interdependence and to make decisions demonstrating that we have a stake in each other, that we can indeed care for each other and the physical planet we share.

Wisdom in groups emerges as a product of commitments we make with ourselves and to each other. These stances are not abstract rules but tangible practices that must be renewed each time we are in groups. They are essentially commitments and attitudes that foster collaboration and positive collective action.

Developing wisdom in community is to constantly learn and relearn that expedience in the short term - whether for efficiency or profitability - can lead to disasters in the long term in financial, ecological, political, social, and spiritual spheres.

Our characterization of collective folly is that sound judgment is not feasible when there is forced or false agreement in groups. We also show how group polarization sets the stage for risky and even dangerous decisions to be made. How we navigate between false agreement and polarization is the kind of mastery that collective wisdom represents.
