In an effort to better understand variation in jealous response cross-culturally, the researchers of this study surveyed 11 different populations, eight of which were small-scale societies on five different continents (Mayangna, Shuar, Tsimane, Himba, Hadza, Karo Batak, Mosuo, and Yasawa) and three of which were in urban settings (Los Angeles, CA, "urban India" (online), and Okinawa, Japan). Looking at the differences between sexual and emotional infidelity, researchers found that greater paternal investment and lower frequency of extramarital sex are associated with more severe jealous response.

Results suggest that men and women are equally concerned with the sexual activities of their spouses, however, tactics used in response to infidelity vary by gender.

This study relates female contributions to a variety of social variables. The author divides responses to high female contribution to subsistence into two categories: adaptive (i.e. increased exogamy, polygyny, and bridewealth) and attitudinal (i.e. increased valuation of girls and premarital permissiveness). It is proposed that where women contribute more, “they are perceived less as objects for male sexual and reproductive needs and more as a person in their own right” (149).
