INTRODUCTION

English translation pending.

CORE DEFINITION

From the I Ching, the principle holds that things alternate between waxing and waning: what reaches fullness declines and what reaches emptiness recovers. The core proposition is that states are phases in a cycle rather than fixed levels, so present conditions carry information about the direction of change. The qualification is that the cycle does not prescribe timing or amplitude, so it warns against linear extrapolation without predicting when the turn occurs. Its practical use is counter-cyclical positioning.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Cycle position: ask where the current state sits within its cycle rather than treating it as a level. - Counter-cyclical move: prepare an exit at the peak and accumulate capability at the trough. - Extrapolation check: test whether your forecast simply extends the present trend indefinitely.

Anchor fast decisions

Growth consumes the conditions that enabled it, such as available demand, slack resources, or attention, while decline creates the conditions for recovery by removing excess and lowering costs. Because the same process that produces the current state also erodes it, states tend to reverse rather than persist, which makes the observed level a poor basis for forecasting the next period.
