Among humans, paternal investment has been shown to enhance both fertility and offspring survival. While psychological and ecological influences on human paternal investment are relatively well documented, cultural influences remain less well understood. It has been proposed that religion can be an important socio-cultural factor shaping paternal investment. First, religions often instill pro-family values in fathers, potentially increasing their investment. Second, if religions promote pro-family values in mothers, these values may be communicated through religious behaviours, encouraging greater paternal investment. Alternatively, fathers may use maternal religiosity as a strategic cue of maternal pro-family commitment to reduce their own investment, shifting responsibility to mothers. To evaluate these hypotheses, we analyse data from 1238 children under 17 years old across 822 households in India and Bangladesh. Our findings suggest that in India, paternal religiosity is positively associated with fathers’ housework assistance and emotional support to mothers. In Bangladesh, maternal religiosity is positively associated with paternal emotional support to mothers and child provisioning. In both countries, maternal religiosity positively associates with paternal investment among the most religious fathers. These findings indicate that religion plays a complex role in paternal investment, shaped by the interplay of parental religiosity and socio-ecological context.
