Social categories in the making: construction or recruitment?

Abstract Real kinds, both natural and social categories, are characterized by rich inductive potential. They have relatively stable sets of conceptually independent projectable properties. Somewhat surprisingly, even some purely categories (e.g., ethnicity, gender, political orientation) show such multiple projectability. The article explores the origin richness concepts. I argue that existing philosophical accounts provide only a partial explanation, mechanisms boundary formation stabilization must be brought into view for more comprehensive account inductively categories.
