Abstract: Sex differences in religiosity are cross-culturally common and robust, yet it is unclear why sex differences in some cultures are larger than in others. Although women are more religious than men in most countries, religions frequently provide asymmetrical benefits to men at the expense of women. Two global analyses (51 countries and 74 countries) found that country-level gender equality was consistently and negatively associated with religiousness (i.e. religious attendance, reported importance of God and frequency of prayer) for men, more than for women, leading to a larger sex difference in religiousness in more gender-equal countries. Results were especially robust for religious attendance, and hold accounting for country-level wealth, as well as individuals' religious affiliation, the moralization of sexuality, age and education level. We interpret results through a rational choice lens, which assumes that people are more drawn to religion when it is consistent with their reproductive goals.

4. Discussion

These data show that gender equality across cultures consistently and negatively predicts religious belief and behaviour among men, but the effect is small and inconsistent for women. This interaction between gender equality and participant sex holds in most of the models we ran, even when accounting for the clustering of countries within sub-regions, the religious denominations of participants, sociosexuality, age, education and country-level wealth.

The results were particularly strong with religious attendance as an outcome; in all such models there was a consistent negative relationship between gender equality and religious attendance for men, but no effect for women. We suggest that religious attendance (versus private religious behaviour or belief) is the outcome most relevant to our hypothesis. That is, it is attendance and overt participation that we would expect to be associated with the reproductive outcomes of interest. Overt religious participation may allow men to more easily monitor women, police sexual behaviour or to signal their value as a mate via religious commitment.

In addition, the focal results were driven by gender equality in education and economic participation, but not political power or health/survival. These results could be consistent with the view of religion as a ‘costly signal’ to indicate qualities such as trustworthiness, dedication to one's family or even simply dedication to one's group [7,37–39,62–64]; gender equality might also influence the payoffs of using religion as a costly signal. For instance, there is some evidence that women's economic dependence on men—which makes paternal certainty more critical—facilitates moralization of promiscuity [65]. It follows, then, that women who are dependent on men (i.e. when gender equality is low) may prioritize signals of paternal investment and long-term commitment; this could, in turn, incentivise men in these societies to use religion as a signal of their willingness to invest in their offspring [7,39].

One could also predict the same pattern by considering other functions of religion. For example, religion fosters cooperation and ingroup cohesion [66,67] and can help people manage their existential insecurities [41]. Indeed, religions are especially attractive to people after facing mortal threats, such as intergroup conflict [68]. One alternative explanation, then, could be that countries that have achieved greater gender equality face fewer threats that require male coalitional coordination (e.g. warfare); therefore, people (particularly men) in these countries are less likely to view religion as necessary. We reiterate, however, that our analyses are unable to reveal the mechanism behind the observed effects, or to adjudicate between alternative explanations.

Our hypothesis stems from a rational choice perspective on religion [9], suggesting that engagement in religious behaviours and beliefs might stem partly from the reproductive benefits people acquire from them [9,16,18]. Because religions often involve costly behaviour [69,70], one should expect religious engagement to be more likely when the benefits outweigh the costs. If indeed one of the functions of religion is reproductive support that often favours men over women, and if the manipulation of women in such ways (e.g. through modesty norms or proscribing sexual promiscuity) is less accepted in more gender-equal societies, the costs may outweigh the benefits for men in these societies, resulting in lower religiousness among men.
