Erving Goffman, you may recall, was a mid-twentieth century sociologist, who, in The Presentation of the Self in Everyday Life, developed a dramaturgical model of human identity and social interactions. The basic idea is that we can understand social interactions by analogy to stage performance. When we’re “on stage,” we’re involved in the work of “impression management.” Which is to say that we carefully manage how we are perceived by controlling the impressions we’re giving off. (Incidentally, media theorist Joshua Meyrowitz usefully put Goffman’s work in conversation with McLuhan’s in No Sense of Place: The Impact of Electronic Media on Social Behavior, an underrated work of media theory published in 1986.)3
