A term used in Howard Bloom
's book Global Brain
Conformity enforcers create a sense of identity in the forms of common languages and traditions. Studies have shown that human brains are so receptive of conformity that it actually changes the wiring of a baby's brain. Bloom goes into detail, giving an example of a society that made heavy use of conformity enforcers, ancient Sparta.
The desire to form a common language, go home for the holidays, and order "what he's having" are all due to conformity enforcers.
