The digit ratio (2D:4D) is considered a proxy for testosterone exposure in utero, and there has been a recent surge of studies testing whether 2D:4D is associated with economic preferences. Although the results are not conclusive, previous studies have reported statistically significant correlations between 2D:4D and risk taking, altruism, positive reciprocity, negative reciprocity and trust. However, most previous studies have small sample sizes gathered from university students and there is also no consensus on the type of analysis (e.g., which hand to analyze or subgroup to focus on) or the preference elicitation method. We present results from a pre-registered large sample study testing if 2D:4D is associated with economic preferences. Data were collected in a representative sample of adults in the German Socioeconomic Panel-Innovation Sample (SOEP-IS), in a sample of about 3450 respondents (about 5 times larger than the previously largest study in this field). Using experimentally validated survey questions, we find no statistically significant association between 2D:4D and economic preferences in the largest study to this date on the topic.

数字比率（2D：4D）被认为是子宫内睾丸激素暴露的代表，最近有大量研究测试2D：4D是否与经济偏好相关。尽管结果不是结论性的，但先前的研究已经报告了2D：4D与冒险，利他主义，正向互惠，负向互惠和信任之间的统计学显着相关性。然而，大多数先前的研究从大学生那里收集的样本数量很少，并且在分析类型（例如，要分析的手或要关注的子组）或偏好激发方法上也没有共识。如果2D：4D与经济偏好相关，我们将提供预先注册的大样本研究测试的结果。数据是在德国社会经济专家组创新样本（SOEP-IS）中的代表性成年人样本中收集的，样本约有3450名受访者（比该领域以前的最大研究大5倍）。使用经过实验验证的调查问题，我们发现迄今为止，在有关该主题的最大规模研究中，二维：4D与经济偏好之间没有统计学上的显着关联。
