The Force which has to be called down from above must be pure and quiet because there are all kinds of forces - it will not do to call them all. And one must have sincerity.
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.
