hierarchy and testosterone

Hierarchies select for testosterone heavy traits. In a world where only the high testosterone people can rise to the top, decisions will be testosterone driven. Hence, if you want to make the world a little less aggressive place, you should start by making the internal structure of the decision making entities less hierarchical. But how do you proceed?

• Keeping the size of the entities small is one option. But competition and scale effects favour consolidation. Hence this will not work out in any sensible economic regime.
• Trying out non-hierarchical organisational structures like holacracy is another option. But these flat fantasies never last too long. None of the large entities can even hope to give them a try.
• Waiting for artificial intelligence to mature seems to be the most feasible option at the moment. AI will dramatically decrease the need for human decision making so that even the largest entities can be run like a small entity.
