Three-Layer Explanation

CORE DEFINITION

A thinking framework, popularised in Chinese decision-making literature, that analyses a phenomenon at three nested levels. The surface level records what is directly observable and the simple cause-and-effect story most people tell. The technical level explains the skills, rules and background knowledge that make the observed result possible. The foundational level asks which general principle about human nature or systems makes the pattern recur. The claim is that problems treated only at the surface get patched rather than solved, and that moving down a level changes what counts as a solution. It is a diagnostic discipline, not an empirical theory: the layers are analytical distinctions, not separate physical realities.
