Systems Thinking Before Systems Thinking Was a Job

People have been thinking in systems since before the vocabulary existed.

People have been thinking in systems since before the vocabulary existed. The irrigation engineer, the midwife, the cathedral mason — each of them held complex feedback loops in their head and reasoned about second-order effects without ever using the phrase.

What the formal discipline contributed was language, not perception. Diagrams, stocks and flows, leverage points. Useful scaffolding. But the underlying cognitive move — seeing a thing as part of a thing — is older than any of the books on the shelf.

When you teach systems thinking, do not start with the diagrams. Start by pointing at something in the room and asking what would change if it were removed. Most people already know how to think this way. They have just been told that what they were doing was not real work.
