Part Three — The Loop Tongue
Sketching a Loop
“A picture is worth a thousand words.”
Words alone still carry some of the linear bias baked into speech. A simple notation removes more of it — not a formal diagramming system requiring training, just four marks, learnable in under a minute, sketchable on a napkin mid-conversation.
An arrow (→) means “feeds into.” Anxiety → checking the phone.
A closed loop (↻) placed after a chain means the chain returns to its own start — a reinforcing Loop, where each lap makes the next lap more likely. Anxiety → checking the phone → brief relief → faster anxiety next time ↻
A half-loop (⤸) means a balancing Loop — one that dampens itself rather than reinforcing, returning toward a middle instead of accelerating away from it. Overwork → exhaustion → forced rest ⤸
A nested bracket [ ] around a chain means “this whole pattern is itself one Local Rule inside a larger version of the same Loop, one scale up.” [Anxiety → checking the phone ↻] → a culture of distraction, built the same way, one person at a time.
That’s the entire notation. It isn’t trying to replace a formal systems diagram — anyone who wants the fuller version has Thinking in Systems and its relatives waiting in Part Four’s further reading. It’s trying to be the version two people can actually use standing in a kitchen, mid-argument, when one of them says “wait, draw what you mean” and a napkin is the only tool available.
