but in fact by the time this semester ends

但实际上在这学期结束时
I will have tell you--told you everything I know.

我就将我所知道的东西全都告诉你们了
And if you stood up and started talking about everything you knew

而如果你们站在这里谈论你们所了解的东西
you'd look really smart too. The best study to show this is a quiz show study,

你们也会显得非常聪明这方面最好的研究是问答节目的研究
which is you take two people and you flip a coin.

找来两个被试抛硬币决定
And one of them is the quiz master and the quiz master gets to ask questions,

其中一个是提问者提问者可以向另一位被试
any question he or she wants. And the other person has to answer the questions.

问任何他想问的问题另一位被试必须作答
And if they play seriously, the quiz master's going to destroy the other person.

如果他们很认真地进行提问者很快会击败另一位被试
"What was my dog's name?" "Well, I don't know."

我的狗叫什么我不知道
"What's the capital of the city in which I was born?" "Well, I don't know."

我出生的城市的省会在哪我不知道
And then you'd expect a third person watching this to say,

你可能会想旁观者看到此情此景会想
"Who cares?It's just--They're just doing this because of the coin they flipped."

谁在乎谁问谁答只不过取决于那个硬币而已
