The objective of this research was to find the structure of adaptiveness in order to use it to organize institutions, whatever their size, from countries to human groups, to generate stable growth. Cultural adaptiveness is the central gravitational force that fosters expansion. It is homologous to institutional expansion processes. The core of the adaptive behavior is to make growth in an environment possible. The unicist ontological structure of adaptiveness includes counterintuitive elements that make it difficult to apprehend because of the pre-concepts people have. The final purpose of cultural adaptiveness is to achieve growth using influence on the environment to produce it. Over-adaptation works as a driver for cultural degradation but also as an energy conservation function in adaptive environments, a fact that can be considered counterintuitive. That is why over-adaptation can only be apprehended if it is experienced.
