Latent function

Manifest and latent functions are social scientific concepts first clarified for sociology by Robert K. Merton. Merton appeared interested in sharpening the conceptual tools to be employed in a functional analysis.

Manifest functions are conscious, deliberate and beneficial, the latent ones the unconscious, unintended and beneficial, and dysfunctions are unconscious, unintended and harmful. While functions are intended (manifest) or unintended (latent), and have a positive effect on society, dysfunctions are unintended or unrecognized (latent) and have a negative effect on society.

Manifest functions are the consequences that people observe or expect. It is explicitly stated and understood by the participants in the relevant action. The manifest function of a rain dance, used as an example by Merton in his 1967 Social Theory and Social Structure, is to produce rain, and this outcome is intended and desired by people participating in the ritual.

Latent functions are those that are neither recognized nor intended. A latent function of a behavior is not explicitly stated, recognized, or intended by the people involved. Thus, they are identified observers. In the example of rain ceremony, the latent function reinforces the group identity by providing a regular opportunity for the members of a group to meet and engage in a common activity.

Peter L. Berger describes a series of examples illustrating the differences between manifest functions and latent dysfunctions:

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.
