Dissing oneself versus dissing rivals: Effects of status, personality, and sex on the short-term and long-term attractiveness of self-deprecating and other-deprecating humor

From the book : Evolutionary Psychology 6 issue 3 : 393-408.
This study explores the adaptive functions and design features of self- and other- deprecating humor.
Sixty-four female and 32 male college students participated in a two- part study.
In the first part, we examined the relationships among participant demographics, personality traits, and preferences for producing different types of humor.
Men report using more other-deprecating humor than women do, and the use of other-deprecating humor decreases with age for both sexes.
In the second part of the study, each participant listened to tape recordings of opposite-sex people who were described as having different levels of status, and who produced different types of humor; then participants rated each person’s attractiveness as a potential short-term and long-term mate.
Humor type and presenter status had no effects on short-term attractiveness, but self-deprecating humor by high-status presenters (but not low-status presenters) increased long-term attractiveness for both sexes.
These results are discussed in the light of sexual selection theory and costly signaling theory.
