Abstract: Attention is brought to the existence of incongruity in the definition of reliability in the literature, and some unnecessary controversies and confusions which result. A conventionalization of the meaning of reliability at a conceptual, model-free level is proposed. Through the exploration of two paradoxes, this article attempts to address some potential misconceptions about reliability, validity, and psychometrics.
