前景理论预测了四倍的风险态度，这意味着人们会寻求低概率收益和高概率损失的风险，而会厌恶低概率损失和高概率收益的风险，因为他们在概率较低时过分看重概率。风险态度的四重模式得到了之前针对主流工业化人群的几项研究的支持，但之前从未在非工业化社会中进行过测试。在这项工作中，我们研究了中国独龙族的四重风险态度的稳健性，独龙族是一个与现代文明隔绝、只有 4000 名成员的小社会。我们采用简单的不同概率得失抽奖的方法来诱发37名独龙村民的风险态度。我们的结果支持了前景理论的预测，因为独龙族人追求低概率收益的风险，厌恶低概率损失的风险。然而，尽管他们表现出降低收益（损失）风险寻求（风险厌恶）程度的倾向，但当前景概率增加到50%时，他们的风险态度并没有发生逆转。总之，我们的结果表明在这个非工业化的小社会中存在右移的权重函数。这种偏差可能是由于独龙族特殊的生活状况、对金钱回报的敏感度以及诱导程序造成的。
Prospect theory predicts a four-fold risk attitude, which means that people are risk seeking for low-probability gain and high-probability loss and risk averse for low-probability loss and high-probability gain because they overweight probability when it is low. The four-fold pattern of risk attitude has been supported by several former studies with mainstream industrialized populations but has never previously been tested in a non-industrialized society. In this work, we examined the robustness of the four-fold risk attitude in the DuLong minority ethnicity in China, which is a small society with only 4,000 members that is isolated from modern civilization. We used simple lotteries for gain and loss with different probabilities to elicit the risk attitude of 37 DuLong villagers. Our results support prospect theory predictions in that DuLong people are risk seeking for low-probability gain and risk averse for low-probability loss. However, although they showed a tendency to decrease their degree of risk seeking (risk aversion) for gain (loss), their risk attitude did not reverse when the probability of the prospect increased to 50%. In summary, our results suggest a right-shifted weighting function in this non-industrialized small society. The deviation might be caused by the particular living situation of the DuLong people, their sensitivity to monetary payoffs, and the elicitation procedure.
