Wiki Version:
Both sexes choose mates based on qualities that will enhance offspring viability and quality. The Reproductive Compensation Hypothesis (RCH) predicts that parents who mate under constraint will increase their reproductive effort and investment in offspring to compensate for lowered offspring viability. One possible type of mate choice constraint in humans is arranged marriage in which parents or others choose mates. In order to test the RCH in humans, we examine whether there are differences in both partner traits, parental investment, and alloparental help between women in arranged marriages and those in self-choice marriages using data from the Indonesian Family Life Survey. The rate of arranged marriage has declined from approximately 34% of marriages in 1993 to only 11% in 2015. Except for education level and the personality trait of originality, no differences were found in mate characteristics between the husbands of women in self-choice compared to arranged marriages. Marriage type did not significantly correlate with parental investment except for number of live births where women in self-choice marriages had more offspring (controlling for marriage duration) than woman in arranged marriages, counter to predictions. It is possible that arranged marriage is not a true constraint on mate choice in humans. -- Associate Professor & Graduate Coordinator, Department of Anthropology Program Coordinator, Data Science for the Liberal Arts Boise State University *Pronouns: she/her/hers* personal website <https://www.kristinsnopkowski.com/>
