A structured inferential method in which conclusions are derived from one or more general premises such that, if the premises are true, the conclusions must necessarily follow. Parameters: (1) at least one universal premise, (2) a rule of inference (e.g. modus ponens, syllogism), and (3) a conclusion logically entailed by those premises. Persistence mechanism: sustained through teaching, formal notation systems, and disciplined practice in mathematics, philosophy, law, and computer science.

Definition
Why it is in scope
a human-made method of reasoning in which conclusions necessarily follow from general premises — a structured inferential practice built into formal logic, mathematics, and argumentation for deriving specific conclusions from universal statements

Test direction: specific→general (Law 9). Deductive-reasoning IS a specific kind of reasoning — it is the form of inference where conclusions necessarily follow from universal premises. A competent speaker would classify deductive reasoning as 'a type of reasoning.' Files against nearest kind 'reasoning' per Law 9. Direction correct.

Deductive reasoning needs logic to operate now: it is the application of logical principles to derive conclusions from premises. Remove logic and deductive reasoning cannot function — it has no working mechanism without logical rules. Object-level dependency, not meta-level.

Syllogism is a specific form of deductive reasoning: a structured argument where conclusions follow necessarily from premises. Direction: specific (syllogism) → general (deductive-reasoning). A competent speaker would call syllogism a deductive-reasoning pattern. Nearest kind: deductive-reasoning is more specific than logic (my previous DEPENDS_ON→logic error), and syllogism IS a kind of deductive-reasoning.
