The Data of Levy and Levy (2002) “Prospect Theory: Much Ado About Nothing?” Actually Support Prospect Theory
指出Levy和Levy（2002）声称反驳前景理论的数据，在正确应用前景理论公式后完全符合其预测，他们的错误在于忽略了概率权重。
Levy and Levy (Management Science2002) present data that, according to their claims, violate prospect theory. They suggest that prospect theory's hypothesis of an S-shaped value function, concave for gains and convex for losses, is incorrect. However, all the data of Levy and Levy are perfectly consistent with the predictions of prospect theory, as can be verified by simply applying prospect theory formulas. The mistake of Levy and Levy is that they, incorrectly, thought that probability weighting could be ignored.
