Over-adaptation implies stagnation. The stagnation is a consequence and over-adaptive behaviors are the drivers that generate stagnation.
Cultural expansion requires being able to influence the environment and then use the over-adaptive behavior in order to save energy.
It requires being able to influence the environment in a way that generates growth.
When this influential attitude does not exist, whatever the reasons, the over-adaptive process has begun.
This necessarily generates stagnation in the environment. Standing still in an environment that is evolving produces involution measured in terms of the vital space that is being occupied in the context.
NOTE: The Unicist Research Institute was the pioneer in using the unicist logical approach in complexity science research and became a private global decentralized leading research organization in the field of human adaptive systems. It has an academic arm and a business arm.
