Manifest and latent functions and dysfunctions
Manifest and latent functions and dysfunctions are concepts introduced by Robert K. Merton.
Manifest functions are the consequences that people observe or expect, latent functions are those that are neither recognized nor intended. While Talcott Parsons tends to emphasize the manifest functions of social behavior, Merton sees attention to latent functions as increasing the understanding of society: the distinction between manifest and latent forces the sociologist to go beyond the reasons individuals give for their actions or for the existence of customs and institutions; it makes them look for other social consequences that allow these practices’ survival and illuminate the way society works.
Dysfunctions can also be manifest or latent. Manifest dysfunctions include traffic jams, closed streets, piles of garbage, and a shortage of clean public toilets. Latent dysfunctions might include people missing work after the event to recover.
