Scholars from various disciplines have studied humor since antiquity. Yet, over the centuries, these researchers have also struggled to conceptualize a viable, well-accepted notion of humor. Beyond pleasure and amusement, people use humor for a variety of social functions. On the one hand, humor can cause others to like the humorous source more, attract regard, ease conversations, promote expression and the exchange of ideas, introduce new topics of discussion, or smooth interactions. On the other hand, in aggressive forms, humor can halt verbal interactions, modify the usual rules of conversation, communicate critiques, or contribute to the creation of subversive environments.
