The ratio of index to ring finger length (2D:4D) is used as a proxy for prenatal sex hormone exposure. It has been hypothesised to correlate with religiosity, though no published research has explored this possibility. Here, we initially examined 2D:4D in relation to self-reported religious affiliation and questionnaire measures of general religiosity, spirituality, religious fundamentalism, and religious commitment in male ( = 106) and female ( = 105) university students (Study 1). Although no significant correlations were observed between 2D:4D and the questionnaire measures, females who affiliated with organised religions had higher digit ratios compared to agnostic or atheist females. Study 2 attempted to replicate these findings in an adult general population sample ( = 172 males, = 257 females), but did not observe significant effects in either sex. Overall, these findings suggest that high 2D:4D may be relatively-specifically associated with religious affiliation in young, highly-educated, females.
食指与无名指长度之比（2D:4D）被用作产前性激素暴露的一个指标。据推测，它与宗教虔诚度相关，不过尚未有已发表的研究探讨过这种可能性。在此，我们首先在106名男性和105名女性大学生中（研究1），研究了2D:4D与自我报告的宗教归属以及关于一般宗教虔诚度、灵性、宗教原教旨主义和宗教奉献的问卷调查指标之间的关系。尽管未观察到2D:4D与问卷调查指标之间存在显著相关性，但与不可知论或无神论女性相比，隶属于有组织宗教的女性的指长比更高。研究2试图在一个成年普通人群样本（172名男性，257名女性）中重复这些发现，但在任何一种性别中均未观察到显著影响。总体而言，这些发现表明，高2D:4D可能相对特定地与年轻、受过高等教育的女性的宗教归属相关。
