QUOTE : In 1959, the sociologist Erving Goffman laid out a theory of identity that revolved around playacting. In every human interaction, he wrote in The Presentation of Self in Everyday Life, a person must put on a sort of performance, create an impression for an audience. The performance might be calculated, as with the man at a job interview who’s practiced every answer; it might be unconscious, as with the man who’s gone on so many interviews that he naturally performs as expected; it might be automatic, as with the man who creates the correct impression primarily because he is an upper-middle-class white man with an MBA. A performer might be fully taken in by his own performance—he might actually believe that his biggest flaw is “perfectionism”—or he might know that his act is a sham. But no matter what, he’s performing. Even if he stops trying to perform, he still has an audience, his actions still create an effect.
