Humorous Threat Persuasion in Advertising: The Effects of Humor, Threat Intensity, and Issue Involvement

Abstract
Using humor to communicate threatening information in advertising can often be observed in practice, but scholars have seldom investigated its effects. Drawing from dual processing models, the current study proposed that response to humor in threat persuasion would depend on the individual's level of issue involvement. This proposition was tested in two experiments. In Study 1, a significant humor and issue involvement interaction effect emerged for threat persuasion ads; low-involvement individuals rated the humor ad more positively than the nonhumor ad, and the opposite was true for high-involvement individuals. With threat intensities varied in Study 2, the results indicated that the effectiveness of various threat intensity and humor combinations depended on the individual's issue involvement. Implications for both theory and practice are discussed.
