We study how the ratio between the length of the second and fourth digit (2D:4D) correlates with choices in social and risk preferences elicitation tasks by building a large dataset from five experimental projects with more than 800 subjects. Our results confirm the recent literature that downplays the link between 2D:4D and many domains of economic interest, such as social and risk preferences. As for the former, we find that social preferences are significantly lower when 2D:4D is above the median value only for subjects with low cognitive ability. As for the latter, we find that a high 2D:4D is not correlated with the frequency of subjects' risky choices.
我们通过构建一个来自五个实验项目、包含800多名受试者的大型数据集，研究第二和第四指长度之比（2D:4D）与社会及风险偏好诱导任务中的选择是如何关联的。我们的结果证实了近期文献中淡化2D:4D与许多经济相关领域（如社会和风险偏好）之间联系的观点。至于前者，我们发现仅对于认知能力较低的受试者，当2D:4D高于中位数时，社会偏好显著更低。至于后者，我们发现高2D:4D与受试者风险选择的频率并无关联。
