Sociofact is a term coined by Sir Julian Sorell Huxley, used together with the related terms "mentifact" (sometimes called a psychofact) and "artifact" to describe how cultural traits take on a life of their own, spanning over generations. This idea has been related to memetics. The idea of the sociofact was developed extensively by David Bidney in his textbook Theoretical Anthropology. Bidney used the term to refer to objects which consist of interactions between members of a social group. The concept has been used by philosophers and social scientists in their analyses of varying kinds of social groups. For instance, semiotician of music Charles Boilès, in a discussion of the semiotics of the tune "Taps", claims that although it is a single piece of music, it can be seen as three distinct musical sociofacts: as a "last call" signal in taverns frequented by soldiers, as an "end of day" signal on military bases, and hence symbolically as a component of military funerals. The claim has been made that sociofactual analysis can play a decisive role for the performance of, and collaboration within, organizations.
