categorization

Test: categorization IS a specific kind of classification (Law 9). Categorization is the practice of grouping items by shared features; classification is the broader system of organizing by criteria. Direction: specific → general. INSTANCE_OF is correct.

Categorization operates by matching inputs against stored patterns. Remove memory and there is no stored category to match — categorization stops operating entirely. This is constitutive: categorization requires a memory mechanism to store and retrieve category definitions. The removal test passes operationally, not just conceptually.

Taxonomy is the systematic practice of categorizing entities into hierarchical classes. Remove categorization as a cognitive practice and taxonomy ceases to operate — taxonomy IS formalized categorization. This is constitutive, not facilitative.

Classification IS structured categorization — the systematic application of categorization to organize entities into named groups. Without categorization (the cognitive act of grouping by shared features), classification cannot operate. Constitutive dependency.

Indexing is constitutively dependent on categorization: an index organizes items by grouping them into categories for retrieval. Remove categorization — the very operation of grouping — and indexing cannot function. This is present-tense necessity, not mere association.

Sensemaking operates by imposing categories on experience. Remove categorization and sensemaking has no mechanism to distinguish, classify, or structure information. Present-tense constitutive dependency.

Typology is a specific systematic classification scheme — a method of organizing things into types and categories. It is a particular kind of categorization, not a whole-part or dependency relation.

Indexing requires categorization as a constitutive substrate — you cannot create an organized index without first grouping items into categories. Remove categorization and indexing ceases to function; an un-categorized list is merely a list, not an index.

Stereotypes are cognitive shortcuts that operate on category membership judgments. They depend on categorization being active right now — without the capacity to sort entities into categories, stereotypes cannot function at all. This is present-tense necessity.

Direction tested by removal: remove categorization and ontology stops operating — ontology IS a system for organizing knowledge into categories. Without categorization capacity, ontology cannot function. This is constitutive, not meta-level.

Tagging IS a specific kind of categorization — organizing items by assigning discrete labels/tags to them. A competent speaker would call tagging 'a categorization method'. INSTANCE_OF test passes.

Representativeness-heuristic judges probability by how much an instance resembles a category prototype. The mechanism requires forming and comparing against category representatives — remove categorization and the prototype-matching process that constitutes the heuristic stops operating. This passes the removal test (Law 8): not merely sayable without categorization, it ceases to FUNCTION.

Removal test (Law 8): remove categorization — does prejudice stop OPERATING? Yes. Prejudice is a preconceived judgment applied to categorized targets — it cannot function without the capacity to categorize. Categorization is the mechanism prejudice exploits. Direct object-level dependency, not meta-level.

Label DEPENDS_ON categorization: the removal test passes — remove the capacity to categorize (group things by shared features) and labels cease to function. A label's entire operation is to mark and identify a category; without categorization as a cognitive and social capacity, labels are just arbitrary marks with no classificatory work. Not meta-level (Law 2b) — this is object-level: labels literally cannot operate without categorization.

To recognize variation you need a category or set as reference frame. Remove categorization (the practice of grouping items into kinds) and the concept of variation-within-a-set loses its operative meaning — you cannot identify what varies without something to vary within. The removal test passes: without categorization as a practice, variation ceases to operate as a distinguishable concept. Not meta-level — this is object-level: variation as a concept constitutionally requires a categorical frame.

Boundary work draws boundaries between domains of knowledge or practice. It requires categories to draw boundaries between — remove categorization and boundary work loses its mechanism. Per Law 8: remove-Y-now-does-X-stop-OPERATING.
