“Both sexes are likely to rank a good sense of humor next to the top of their lists. The trait is so sought after that it has its own acronym – GSOH – in dating ads. It was found that women want a man who is a humor generator while men seek a humor appreciator. The basic difference is that males tend to use humor to compete with other men while women tend to use it to bond with others. The allure of male humor is so strong that female laughter may have evolved as a signal of sexual interest. Indeed a German study found that when male or female strangers engaged in natural conversation the degree to which a woman laughed while talking to a man was indicative of her interest in dating him. How much the woman laughed also predicted the man’s desire to date her. The study indicates that humor likely developed through sexual selection because it is most desirable in romantic relationships. A woman would do well to find a man who enjoys her humor because that’s an indication of his own self-esteem and willingness to be supportive. Conclusion – a playful and humorous frame of mind is protective.”
