New publication by Annemarie Hasnain and Kristin Snopkowski in the journal, Evolution and Human Behavior. Their article, “Maternal investment in arranged and self-choice marriages: A test of the reproductive compensation and differential allocation hypothesis in humans” examines how mothers invest in their children depending on their marriage type: arranged marriage or self-choice using a longitudinal sample of Indonesian women. Results show no statistically significant differences for most measures, including birth weight, breastfeeding duration, and offspring height and weight. But, there is a small statistically significant difference in the number of children born and living children, where women in arranged marriages have slightly fewer children than those in self-choice marriages. This mirrors some research in other species that show that females have greater reproductive success when they are free to choose their own mating partners.
