Induction
noun /ɪnˈdʌkʃən/ — Reasoning from specific to general — building a principle from observed cases.
Definition
The inference of a general law from particular instances; the process of inducting someone into a role; the generation of an electric current by changing magnetic fields.
Beyond the definition
Induction is the scientist's core method — from many observations, a general principle. It is more tentative than deduction: the inductive conclusion is always provisional, waiting for the next observation that might overturn it. Science is inherently humble in this way.
Origin & history
From Latin inductio — a leading in (from inducere: to lead in, from in: in + ducere: to lead). Leading in — induction as the movement inward from particular cases to the general principle.

Induction vs deduction
Induction reasons *upward* from specific observations to a general principle — the scientific method, always provisional. Deduction applies a general rule *downward* to reach a specific conclusion — the logical method, certain if the premise holds. Sherlock Holmes claimed to use deduction but usually used induction: he observed particulars and built a theory. Science runs on induction; mathematics runs on deduction.

Fictional scene
Learning from Geological Specimens

A naturalist’s desk is arranged with varied rocks, a fossil, and quartz crystals, with a cutaway cliff showing strata in the background.
The study of these varied geological specimens represents induction, as the naturalist infers general laws about the earth's history from these specific, individual instances. By observing the patterns in each rock, they build a broader, general understanding of the geological environment.
