Effects of including humorous material in a persuasive sermon

Abstract
It was hypothesized that the inclusion of humor in a persuasive sermon would (1) increase the sermon's persuasiveness, and (2) increase the speaker's ethos ratings. Results failed to support either hypothesis, although the results regarding speaker ethos ratings were in the expected direction. The study suggests that the subjects exposed to the humorous sermon may have reacted to some aspects of the speaker's ethos more than to others.
