INTRODUCTION

English translation pending.

CORE DEFINITION

Like attracts like is a principle from the Chinese classical tradition, expressed in the Yijing as things responding to their own kind, and it parallels homophily in social network research. Its core proposition is that similarity in attributes, goals, or resonance produces aggregation, so understanding which dimension of similarity matters is what allows groups and matches to be designed rather than merely observed. The key qualification is that similarity is not always beneficial: homogeneous groups reinforce shared assumptions, which is why complementarity across other dimensions often carries more value than resemblance.

SCAFFOLDING EFFECT

Reduce cognitive load

- Use dimension scan: identify which shared property actually drives the clustering you see. - Use match design: pair people or systems on the dimension that determines their fit. - Use diversity check: add deliberate heterogeneity where shared assumptions would otherwise harden.

Anchor fast decisions

Interaction is cheaper between parties that already share vocabulary, expectations, and goals, so those pairs find each other and stay together more easily than dissimilar ones. Repeated interaction then strengthens the similarity, because shared context accumulates and each side adapts to the other. The same process explains matching in systems, where entities with compatible characteristics select each other and produce stable clusters. The risk is that the mechanism operates on whatever dimension is salient, so a group can converge on a shared assumption nobody has independently checked.
