What does it mean that an integrated schema set is a worldview?

Your fully integrated collection of schemas is your functional worldview.

Example: A software architect who has integrated schemas about distributed systems, organizational behavior, economic incentives, and human cognition doesn't just make 'technical decisions.' They make decisions through a worldview — a coherent lens that connects how systems fail, how teams behave, why incentives misalign, and what cognitive biases distort planning. When asked 'should we adopt microservices?' they don't answer from one schema. They answer from a worldview that synthesizes all of them simultaneously.

Try this: Map your current worldview. Pick a decision you recently made and trace backward: what schemas did you draw on? Write each one down (e.g., 'people respond to incentives,' 'complex systems fail at boundaries,' 'first impressions are unreliable'). Now draw the connections — which schemas reinforce each other? Which ones are isolated, disconnected from the rest? The clusters you find are the load-bearing structure of your functional worldview. The isolated schemas are where integration work remains.
