So a standard economist, somebody who believes in rationality, would say, "You know what? The cost of lifting the pencil and marking a "V" is higher than the possible benefit of the decision, so that's why we get this effect."
所以一个典型的经济学家、一个相信人是理性的人会说， “你知道吗？提起铅笔打一个勾所付出的代价， 要比做这个决定 可能带来的利益大。" 这就是为什么我们得到这个结果。
