• In mathematics and logic, as well as in theoretical physics, it refers to the proposition that a formal theory or a physical theory contains no contradictions. See consistency proof.
• In statistics, consistency refers to a property of estimators.
• In decision theory, a voting system is called "consistent" if and only if it guarantees that whenever option A is the winner both in district 1 and district 2 then option A must also be the winner in the combined district.

Consistency is also occasionally used as a synonym for density or viscosity.
