Sociologist William Martineau (1972) proposed that humor functions as either a “lubricant” or as an “abrasive” for social interaction in both intra- and intergroup settings. What is meant by intragroup humor and what are some ways that humor is used as a social lubricant and as a social abrasive in intragroup settings? From the framework of Social Identity Theory, how does out-group disparagement humor affect cohesion among members of an in-group?
