Paradigm shifters are the outsider that homogeneous societies fear. It is those unlike ourselves who will provide the source for new wealth and new solutions to societal problems. You can only access these people if you are open to diversity because, by definition, outsiders must be different from you. Seeking mutualism rather than self-similarity will provide long term success. Conclusion What we have is a loop, perhaps some would call a system of development.
Diversity provides long term robustness and the ability to survive major system trauma.
Diversity creates a larger universe of options through the results of mutualistic combinations. Diversity is the result of simple systems iterating over time and the nature of the universe to move forward to greater complexity. Diversity creates through growing complexity the need for new paradigms to understand and interact with that complexity. The source of new paradigms, outsiders, are the result of diversity, not similarity. The fear of outsiders by many societies, ironically, disconnects them from their own future.
