Co-operatives become isomorphic to capital-based companies in aspects they do not notice. One of them is co-operative auditing and diagnosis. Although we know, they are personal and not capital partnerships we usually diagnose them and report to the board about the organizational results as venture capital companies do. If persons and not capital are main goals of co-operatives, we should diagnose persons and report to the persons how they are meeting their goals with the co-operative. After presenting a few slides of CoopIndex 1.0, I invite all interested to participate in the development of a new tool CoopIndex 2.0 which is sponsored by my EU research fellowship. According to me, such diagnosis is indispensable for the development of competency to solve many participation dilemmas of our century. I present nine of them and try to prove that they are deeply rooted in our human nature, and our culture and we really have to be highly competent in seeing their complexity. The historical evidence gathered by Eugeniusz Kwiatkowski proves that the common understanding of the world complexity leads to the development of nations. This law gives us not only hope but also the direction to our efforts.
