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.
