The authors examine a world-wide sample of cultures to assess whether the romantic-sexual kiss is a human universal. They also test for an association between romantic-sexual kissing and social complexity.

This study documents the phenomenon of the 'femme fatale' (a dangerous woman) and 'status fatale' (a dangerous man) cross-culturally. The 'femme fatale' motif is practically universal. Data supports the idea that emotional involvement, rather than sexual gratification, was the primary motivation for seeking out a stranger of the opposite sex. A literature review is provided.

This paper presents research on the factors that promote romantic love as a basis for marriage in non-industrial societies. After a discussion of the previous literature on romantic love in ethnographic societies, the authors used the SCCS, EA, and data from eHRAF to create a data set of 109 cultures and then utilized multiple ordinal regression to test the relationship between different types of families and post-marital residence practices and the importance of romantic love in marriage. The findings show that monogamy is significantly correlated with romantic love, while nuclear family organization and neolocal post-marital residence are not significantly correlated. The presence of polygyny is found to lower the probability of romantic love being a basis for marriage. These findings contradict previous research, which found a relationship between non-neolocal post-marital residence and the presence of romantic love in marriage.

Results also show a relationship between social complexity and responses to infidelity.
