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.

Using paternal investment theory, the authors examine the relationship between paternal confidence and paternal investment in humans.

This article explores the interrelated roles of male parental investment (males' infant/child care and resource provisioning) and male-male competition (variation in male status) on the degree of monogamy or polygyny in a society. Marlowe argues that Degree of parental investment affects females' interest in resource-shopping versus gene-shopping. Also discussed is the idea that male-male competition affects males' inclination toward harem-defense or coercive polygyny. Particular attention is paid to variation in parental investment and male stratification across subsistence types.
