Congruence principle

The term Congruence principle may refer to any undertaking that seeks to align apparently disparate things. Specifically, it may refer to:

• In Economics, the principle of fiscal equivalence, i.e., the false model in which the circle of buyers can be made to equate exactly with the circle of sellers.
• In Education, the notion that principles such as Bloom's Taxonomy assist in maintaining congruence among various educational undertakings.^[1]
• In Linguistics and Etymology, the more contributing languages a linguistic feature exists in, the more likely it is to persist in the emerging language.^[2] See Phono-semantic matching.
• In Mathematics, the application of principles associated with Cavalieri's principle.
• In Medicine, the corollary principle of metabolism that holds that "present-day metabolism holds traces of the primitive chemistry and could serve as a valuable source of inspiration in the elaboration of theories." ^[3]
• In Psychology, a corollary to the principle of cognitive dissonance, the notion that it is impossible for a person (or organization) to live too long where there is incongruence between a belief and a behavior.
