We should not conclude from this that everything depends on waves of irrational psychology. On the contrary, the state of long-term expectation is often steady, and, even when it is not, the other factors exert their compensating effects.
我们不应该由此得出结论,一切都取决于非理性心理的浪潮。相反,长期预期的状态往往是稳定的,即使不稳定,其他因素也会发挥补偿作用。
