In the social sciences, framing comprises a set of concepts and theoretical perspectives on how individuals, groups, and societies, organize, perceive, and communicate about reality. Framing involves social construction of a social phenomenon – by mass media sources, political or social movements, political leaders, or other actors and organizations. Participation in a language community necessarily influences an individual’s perception of the meanings attributed to words or phrases. Politically, the language communities of advertising, religion, and mass media are highly contested, whereas framing in less-sharply defended language communities might evolve imperceptibly and organically over culturaltime frames, with fewer overt modes of disputation.
