In his research, the UT psychologist discovered that jealousy also represented a form of ancestral wisdom that can have useful consequences. It can be an anticipatory response, a preemptive strike to head off an infidelity that might be lurking on the horizon. Properly used, jealousy can enrich relationships, spark passion and amplify commitment, according to Buss. The total absence of jealousy, rather than its presence, is a more ominous sign for romantic partners. It portends emotional bankruptcy.
Studies reveal that more women than men intentionally elicited jealousy.
More women than men apparently evoke jealousy to increase a partner's commitment and to test the strength of a relationship. By evoking jealousy, says the researcher, a woman gains valuable information about the depth and consistency of her partner's commitment. Buss also examined the triggers of jealousy. He points out that women tend to get more jealous concerning issues of emotional infidelity whereas men become more jealous when their partners are guilty of sexual infidelity. The Dangerous Passion also explores why women have affairs and how people cope with jealousy and infidelity.
