The joint impact of humor and argument strength in a print advertising context: A case for weaker arguments

Humor is used extensively in advertising, but with mixed results. Drawing on the heuristic systematic model of persuasion, the authors explore a contingency underlying the impact of humorous executions on ad and brand attitudes for a convenience good. Results of a laboratory experiment with print ads show that the presence (vs. absence) of incidental humor can interact with message characteristics such that humorous ads engender more positive attitudes when they employ weaker arguments, and less positive attitudes when they use stronger arguments. © 1999 John Wiley & Sons, Inc.
