对遗传和环境对宗教信仰影响程度的估计差异很大。这种差异可能部分是由于所研究样本的年龄差异。为了研究宗教性的遗传性和可能的年龄变化，在一对成年男性双胞胎（169对MZ和104对DZ，平均年龄33岁）中，通过自我报告评估了当前和回顾性宗教性。关于宗教信仰的回顾性报告显示，MZ（r= 0.69）和DZ（r= 0.59）双胞胎之间的相关性差异很小。然而，当前宗教信仰的报告确实显示MZ（r= 0.62）比DZ（r= 0.42）的相似性更大。对两种宗教信仰的生物统计学分析显示，与成年期相比，青春期的遗传因素明显较弱（12%对44%），共同的环境因素明显较强（56%对18%）。对总分的内部和外部宗教性分量表的分析显示了类似的结果。这些发现支持了宗教性的遗传性从青少年到成年增加的假设。
Estimates of the degree of genetic and environmental influences on religiousness have varied widely. This variation may, in part, be due to age differences in the samples under study. To investigate the heritability of religiousness and possible age changes in this estimate, both current and retrospective religiousness were assessed by self-report in a sample of adult male twins (169 MZ pairs and 104 DZ pairs, mean age of 33 years). Retrospective reports of religiousness showed little correlation difference between MZ (r=.69) and DZ (r=.59) twins. Reports of current religiousness, however, did show larger MZ (r=.62) than DZ (r=.42) similarity. Biometric analysis of the two religiousness ratings revealed that genetic factors were significantly weaker (12% vs. 44%) and shared environmental factors were significantly stronger (56% vs. 18%) in adolescence compared to adulthood. Analysis of internal and external religiousness subscales of the total score revealed similar results. These findings support the hypothesis that the heritability of religiousness increases from adolescence to adulthood.
