INTRODUCTION

English translation pending.

CORE DEFINITION

A concept from Liu Cixin's The Three-Body Problem, where a weapon collapses a region of three-dimensional space into two dimensions and destroys everything that cannot survive the change. As a competitive metaphor, it describes winning by introducing a new dimension rather than by outperforming the opponent on the existing one: free versus paid, high frequency versus low, platform versus standalone product. The opponent's excellence in the old dimension becomes worthless because the contest no longer takes place there. The strategy requires genuinely new capability, since a price cut alone changes a value on the axis rather than the axis itself.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Dimension inventory: list the axes on which the current competition is scored before choosing a move. - New axis: find a dimension the incumbent cannot follow, such as ecosystem, data, or frequency of use. - Capability check: confirm you actually hold the new dimension, since a price cut is not one.

Anchor fast decisions

Effort invested in a dimension produces returns only while that dimension is what buyers compare. Introducing a new axis resets the comparison, so accumulated advantage on the old axis no longer converts into preference. Incumbents cannot follow quickly because their assets, cost structure, and incentives are optimized for the existing axis. The mechanism therefore converts a losing position on one axis into a decisive position on another, at the cost of abandoning the ground you already hold.
