CORE DEFINITION

A relative hardness standard based on 'who can scratch whom'. Diamond (10) can scratch corundum (9), and corundum can scratch talc (1). Hardness is hierarchical.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

A hard-nosed test. In competition, the only test is 'who can scratch whom'. If your technical barrier can be easily scratched by an opponent, and you cannot scratch him, your 'hardness' is lower than his. Don't look at parameters; look at the actual scratch marks.

anchor

Anchor fast decisions

A ten-level relative hardness scale proposed by Friedrich Mohs (talc 1 to diamond 10), ordered by whether they can scratch each other, serving as an empirical identification scale for minerals.
