Definition
Why it is in scope
Presumption is a human-made epistemic and legal mechanism — a rule that treats an unproven fact as established unless rebutted. It is a convention of reasoning and evidence, not a statement about how the world actually is. Humans invented presumptions to manage uncertainty in legal, institutional, and everyday reasoning, and they persist through codification, teaching, and practice.
