Sociologist Robert K. Merton coined the term "unintended consequences" (amongst numerous others), and developed an existing notion of manifest vs. latent functions and dysfunctions.

In particular, Merton notes:

Discovery of latent functions represents significant increments in sociological knowledge .... It is precisely the latent functions of a practice or belief which are not common knowledge, for these are unintended and generally unrecognized social and psychological consequences.
