The Holy Father (and Mother)? Multiple Tests of the Hypothesis That Parenthood and Parental Care Motivation Lead to Greater Religiosity

Abstract

Parenting is a universal element of human life. However, the motivational and attitudinal implications of parenthood remain poorly understood. Given that many major religions prescribe parent-benefiting norms restricting sexual promiscuity and socially disruptive behavior, we hypothesized that both parenthood and parental care motivation would predict higher levels of religiosity. Studies 1 to 3 (N >2,100 U.S. MTurkers; two preregistered) revealed that parental status and motivation were robustly associated with religiosity in Americans, and that age-related increases in religiosity were mediated by parenthood. Study 4a (376 students) found a moderated experimental effect, such that emotionally engaged participants showed increases in religiosity in response to a childcare manipulation. Study 4b then replicated this effect in recoded data from Studies 1 and 2. Study 5 used data from the World Values Survey (N = 89,565) and found further evidence for a relationship between parenthood and religiosity. These findings support functional accounts of the relationship between parenthood and mainstream religiosity.
