Erving Goffman was a highly influential Canadian-American sociologist known for his studies of everyday social interactions and symbolic meaning. His most famous work was Frame Analysis (1974) which introduced the concept of "framing" to describe how people interpret situations based on social expectations and cues. According to framing theory, people make sense of situations through mental frameworks or "frames" informed by past experiences and media messages. These frames can be resistant to change and arouse strong emotions. Framing theory provides insights into how social interactions and media representations reinforce societal norms and power structures through subtle cues.
