This study considers how to compare programs which are designed to save lives. "To estimate the discount rate for lives saved in the future a number of studies have been carried out on the trade-off between saving lives now and in the future. A telephone survey is administered to about 1,700 individuals [in Sweden] to test if the framing of the question affects the estimated trade-off. In one sample the question is framed as saving 100 lives today versus saving x future lives and in one sample the question is framed as saving 100 future lives versus saving y lives today. The result shows that the framing has a major impact on the trade-off."
本研究探讨了如何比较旨在拯救生命的项目。“为了估计未来拯救生命的贴现率，已经开展了一些关于现在和未来拯救生命之间权衡取舍的研究。对（瑞典的）约1700人进行了电话调查，以测试问题的框架是否会影响估计的权衡取舍。在一个样本中，问题的框架是今天拯救100条生命与未来拯救x条生命，而在另一个样本中，问题的框架是未来拯救100条生命与今天拯救y条生命。结果表明，框架对权衡取舍有重大影响。”
