We can measure the discrepancy between what we think we know and what we actually know by simply asking people, after they have given their initial ratings, to tell us how some things work in as much detail as they can and then to rate their knowledge again in light of their attempt to explain.
在人们给出他们的初始评级后，我们只要让他们尽可能详细地告诉我们某些事物的运作方式，然后再根据他们试图作的解释再次评定他们的知识，就可以衡量我们认为我们所知道的和我们所实际知道的差距了。
