我们系统地研究了指数比（2D：4D）（产前睾酮水平的生物标志物）与两种个人风险承担措施之间的联系：（i）对具有真实的货币激励的彩票的风险偏好（RP）和（ii）自我报告的风险态度（RA）。我们发现，右手和左手的数字比例与RP显着相关：数字比例较低的受试者倾向于选择风险较高的彩票。然而，这两个数字比率与自我报告的RA无关。
We systematically investigate the links between the digit ratio (2D:4D)a biomarker for prenatal testosterone exposureand two measures of individual risk taking: (i) risk preferences (RP) over lotteries with real monetary incentives and (ii) self-reported risk attitude (RA). We find that both the right-hand and the left-hand digit ratio are significantly associated with RP: Subjects with lower digit ratios tend to choose riskier lotteries. Neither digit ratio, however, is associated with self-reported RA.
