Manifest Functions

Manifest functions refer to the intended and recognized consequences of a deliberately executed social behavior or action. Upward social mobility, for example, is a manifest function of international labor migration undertaken by populations seeking to improve their economic conditions. Robert K. Merton gave the original explication of manifest functions in Social Theory and Social Structure in 1957.

Merton contrasted manifest functions with latent functions, which are unintended and generally unrecognized consequences. For instance, the functioning of a university campus as a marketplace for finding marital partners can be considered to be a latent function of the manifest function of providing higher-level education. As Merton explained, other social theorists, such as Karl Marx, Emile Durkheim, and William I. Thomas and Florian Znaniecki, implicitly addressed manifest and latent functions in their writings.

Merton acknowledged borrowing the terms manifest and latent from Freud. This is insightful because it demonstrates how analysts working from a systems perspective could move easily between sociological and psychological perspectives. What brought these analysts together across the fields of human behavior, such as anthropology, sociology, and psychiatry, was that they conceptualized their scientific objectives in terms of the functioning of a system, whether of a culture, society, or of the mind. This theoretical convergence decreased in the late 20th century when interdisciplinary boundaries became more rigid.

The decline of social systems analysis in sociology in the late 20th century reduced the sociological interest in explicit analyses of manifest and latent functions. Social analysts used new perspectives to frame questions about sources and outcomes of social action. One perspective, human agency, gave almost total weight to conscious, willful human action, deemphasizing if not eliminating altogether the significance of impersonal social forces that underpin social change. Anthony Giddens (1995) has offered a partial compromise of sorts through his structuration theory. According to this theory, human agents are knowledgeable practitioners of social action, but their knowledgeability has bounds of unacknowledged conditions and unintended consequences. This theorizing moves manifest and latent outcomes closer to the sphere of human consciousness. In other worlds, manifest and latent functions are properties of a knowledgeable human world, but given the imperfections of knowledgeability, the outcomes of willful social action can reach beyond the bounds of human knowledge and intention.

Merton did not reduce manifest functions to an absolute condition. An “item,” he explained, can have more than one manifest function, and different manifest functions can have similar outcomes. Moreover, what constitutes a manifest function for one group can constitute a dysfunction for another group. An example of this case is the investment of U.S. companies in Chinese manufacturing. While this business strategy keeps prices down for U.S. consumers and provides some relief for unemployed and subemployed workers in China, it decreases employment opportunities for the U.S. manufacturing workforce.

Globalization is changing the landscape across which manifest functions take effect. Early studies observed the manifest and latent functions of tribal cultures, but research today must measure the impacts of manifest functions across highly populated and interconnected world regions.
