Definitionv1DF-153
Calibration instrument
a person or system that provides external data about systematic errors in one's perception or behavior that cannot be detected through introspection alone
Why This Is a Definition
This definition precisely establishes what a calibration instrument is by identifying its key characteristics: it provides data about systematic errors, it operates outside of introspection, and it serves as a corrective mechanism. The definition distinguishes it from mere mirrors or feedback sources by emphasizing the systematic error detection aspect.
