homeostatic property cluster theory

Homeostatic Property Cluster (HPC) theory suggests that the concept of a category, like a scientific or everyday group, is based on a set of interconnected characteristics that tend to occur together and remain relatively stable over time. These characteristic features form a "cluster," although not all members have every trait. Think of it like a family image—most family members share some common features, but there can be variation. The "homeostatic" aspect means this cluster maintains its core features despite individual differences. This approach explains how categories are flexible yet cohesive, accommodating diversity within a shared framework.
