Prenatal androgens have organizational effects on brain and endocrine system development, which may have a partial impact on economic decisions. Numerous studies have investigated the relationship between prenatal testosterone and financial risk taking, yet results remain inconclusive. We suspect that this is due to difficulty in capturing risk preferences with expected utility based tasks. Prospect theory, on the other hand, suggests that risk preferences differ between gains, losses and mixed prospects, as well as for different probability levels. This study investigates the relationship between financial risk taking and 2D:4D, a putative marker of prenatal testosterone exposure, in the framework of prospect theory. We conducted our study with 350 participants of Caucasian and Asian ethnicities. We do not observe any significant relationship between 2D:4D and risk taking in either of these domains and ethnicities.

风险态度和数字比率（2D：4D）：来自前景理论的证据

产前雄激素对大脑和内分泌系统的发育具有组织作用，可能会对经济决策产生部分影响。许多研究调查了产前睾丸激素和财务风险承担之间的关系，但结果仍不确定。我们怀疑这是由于难以捕获预期的基于实用程序的任务的风险偏好。另一方面，前景理论表明，风险偏好在收益，损失和混合前景之间有所不同，并且对于不同的概率水平也有所不同。这项研究在前瞻性理论的框架内研究了财务风险承担与2D：4D之间的关系，2D：4D是产前睾丸激素暴露的公认标志。我们与350个白种人和亚洲种族的参与者进行了研究。
